Timer Device

FIELD OF INVENTION

The present invention relates to a timer device and to a method of manufacturing such a timer device.

BACKGROUND

Timing of competitions and games is normally performed using a stopwatch.

There are known conventional stopwatches that comprise a display on the top surfaces and buttons located next to the display, disposed on the stopwatches sidewalls. One of these buttons is used to start and/or stop the operation of the stopwatch thus changing the display contents accordingly.

To operate the start and/or stop ("start/stop button") button of one such conventional stopwatch, a user has to hold the stopwatch in one hand and depress the start/stop button as required. Further, as the size of the start/stop button is small compared to the conventional stopwatch sidewall area, the conventional stopwatch becomes more appropriate in scenarios where a person, who is not taking part in a game which is being timed, operates the stopwatch.

Consider the scenario where a user wants, by himself, to measure the time he takes to complete a game requiring two hands, such as cup stacking. A first time interval occurs when the user's hand is released after starting the conventional stopwatch to play the game and a second timer interval occurs when the user's hand returns to stop the conventional stopwatch. The first and second time intervals are not part of the time taken to complete the game and therefore the time measurement displayed on the conventional stopwatch is an inaccurate reflection of the actual time taken to complete the game.

The requirement of holding the conventional stopwatch to properly operate the start/stop button, along with the start/stop button typically being small, thus do not facilitate accurate game time measurement, especially when the user operates the conventional stopwatch by himself.

There is thus a need to have a timer device that addresses one or more of the above disadvantages.

DETAILED DESCRIPTION

Figures 1A to 1 D show several perspective views 102, 104, 106 and 108 of a timer device 100 built in accordance with one embodiment of the present invention.

The timer device 100 comprises a housing 110, the housing 110 having a top surface structure 112 connected to a bottom surface structure 116.

The top surface structure 112 is circular having a diameter of around 65mm. The top surface structure 112 further comprises one or more light emitting diodes (LED) 124, a display 122 and one or more buttons 126 and 128.

A start/stop button 118 is also disposed on the top surface structure 112 such that a touch surface of the start/stop button 118 extends substantially between two opposing edge portions 120 and 120' of the top surface structure 112. The start/stop button 118 has a truncated circular shape, where the edge of the circular portion of the start/stop button 118 lies along the majority of an inner perimeter of the top surface structure 112. The circular portion of the start/stop button 118 has a diameter of around 56mm. Thus, in this manner, the start/stop button 118 takes up a majority of the top surface structure 112 area. The start/stop button 118 is spring biased at one or more support elements 130, so that the start/stop button protrudes the rim 131 of the housing 110 when the start/stop button 118 is not depressed. When sufficient pressure is placed to depress the start/stop button 118, the start/stop button 118 will move towards the top surface structure 112, along the axes defined by the support elements 130. Upon release of the pressure, the start/stop button 118 will return to its original protruding position.

Having a large start/stop button 118 can produce the following advantages. When the timer device 100 is resting on a surface, only one activation motion in the direction towards the top surface structure 112, is required to depress the start/stop button 118. In this manner, there is no requirement for a user to hold any portion of the timer device 100 when the user operates the start/stop button 118 by tapping on the start/stop button 118 with one hand.

in contrast, conventional stopwatches need to be handheld to operate the start/stop buttons that are disposed on the sidewalls of the conventional stopwatches. Even if the conventional stopwatch rests on a surface, successful engagement of the start/stop button requires an additional force acting in a direction that is opposite to the direction of the force engaging the start/stop button.

Further, the start/stop button 118 provides for a touch surface that spans over at least more than half of the surface area of the top surface structure 112, giving ample area for engaging the start/stop button 118. For successful operation of the start/stop button 118, the force that is applied need not be directed at the center of the start/stop button 118 thus removing the requirement to pay special attention to the exact position the start/stop button 118 is engaged. In comparison, the surface area offered by start/stop buttons disposed on the sides of conventional stopwatches is not as large. In other conventional stopwatches which have start/stop buttons disposed on the top, the start/stop buttons are small and require special attention to ensure that they are successfully engaged.

The above advantages thus allow for the timer device 100 to be used by a person who for example, wants, by himself, to accurately measure the time he takes to complete a game like cup stacking.

The buttons 126 and 128 are disposed a small distance of approximately 2mm away from and on substantially the same plane as the start/stop button 118. The buttons 126 and 128 are spring biased so that the buttons 126 and 128 protrude from the rim 131 of the housing 110 when the buttons 126 and 128 are not depressed. When sufficient pressure is placed to depress the buttons 126 and 128, the buttons 126 and 128 will move in a direction that is substantially vertical to the top surface structure. Upon release of the pressure, the buttons 126 and 128 will return to their original protruding position. The buttons 126 and 128 serve different functions in the different operation modes of the timer device 100, which are further elaborated with reference to Figure 2.

The bottom surface structure 116 has a base portion 114 that is circular and having a diameter that is smaller than the diameter of the top surface structure 112, the base portion 114 diameter being around 60mm. The bottom surface structure 116 is a unitary piece with a sidewall running along the perimeter of the base portion 114, the sidewall having a thickness of around 3 mm and a height of around 14 mm. An electric port 140 is disposed within a groove 141 formed on a portion of the sidewall. An electronic timing circuit (not shown) that is coupled to the start/stop button 118, the buttons 126 and 128, the display 122 and the electric port 140 is disposed inside the housing 110.

The base portion 114 of the bottom surface structure 1 16 comprises one or more bores 132 that extend into the bottom surface structure 116, a pivotable stand 134 and a removable hatch 136.

The bores 132 facilitate the securing of the top surface structure 112 to the bottom surface structure 116 through screws that are introduced into the one or more bores 132. Similarly, the removable hatch 136 is fastened to the base portion 114 using another screw that engages a bore 138.

The pivotable stand 134 is a U-shaped element which engages the base portion 114 through a pair of pivots that are on each leg of the pivotable stand 134. The pivotable stand 134 has two extreme pivoting positions. In the first position, the pivotable stand 134 is depressed against the base portion 114 and thereafter lies resiliently engaged parallel to the base portion 114 (as shown in bottom perspective view 106), allowing the timer device 100 to rest on a flat horizontal surface with the top surface structure 112 being substantially parallel to the flat horizontal surface. In the second position, the pivotable stand 134 defines an angle with respect to the base portion 114 so that the pivotable stand 134 supports the timer device 100 as the portion of the bottom surface structure 116 sidewall adjacent to the buttons 128 and 126 rests on a flat horizontal surface. In the second position, the top surface structure 112 also defines an acute angle with respect to a vertical axis against the flat horizontal surface the timer device 100 is resting on.

The removable hatch 136 facilitates easy replacement of batteries that are used to power the electronic timing circuit 200 (Figure 2).

In the embodiment shown in Figure 1 , the display 122 and the one or more LEDs 124 are disposed underneath the start/stop button 118 and the start/stop button 118 is transparent such that the display 122 and the one or more LEDs 124 are visible through the start/stop button 118. The display 122 has a rectangular shape and has a length of around 30mm and a width of around 15mm.

The components 112, 116, 118, 126, 128, 134 and 136 are made of material such as plastic.

The operation of the timer device 100 will now be described with reference to Figure 2.

Figure 2 shows an electronic timing circuit 200 depicting the main electronic components present in the timer device 100 (Figure 1). The reference numerals 222, 228, 218, 226 and 240 are respectively electronic block representations of the display 122, the button 128, the start/stop button 118, the button 126 and the access electric port 140 shown in Figure 1. The start/stop button 218, button 228 and button 226 are respectively electronically activated when the start/stop button 118 (Figure 1), the button 128 (Figure 1) and the button 126 (Figure 1) are depressed.

In addition to the display 222, the button 228, the start/stop button 218 and the button 226, the electronic timing circuit 200 further comprises a microprocessor 202, a power supply 204, an LED driver circuit 206 and an alarm 232. The electronic timing circuit 200 is disposed in the housing 110 (Figure 1) of the timer device 100 (Figure 1). The button 228, the start/stop button 218, the button 226 communicate with the microprocessor 202 through the sending of electronic signals 208, 210 and 212 respectively. The microprocessor 202 then sends instructions to the display 222, the LED driver circuit 206 and the alarm 232 through signals 214, 216 and 230 respectively. The power supply 204 powers the display 222, the microprocessor 202 and the LED driver circuit 206.

The electronic timing circuit 200 provides five operation modes, namely a clock mode, a stopwatch mode, an alarm mode, a clock setting operation mode and an alarm setting operation mode. These five modes are displayed through the display 222. The buttons 228, 218 and 226 perform different functions in each of the electronic timing circuit 200 operation modes, but in general, the button 228 is used to scroll through the five operation modes of the electronic timing circuit 200.

When the electronic timing circuit 200 is in the clock operation mode, the display 222 will show time in an hour, minute and second format, where the digits representing the three fields are respectively arranged from left to right. The display 222 also shows a date. In addition, the display 222 indicates, through the use of suitable icons, whether the alarm 232 has been activated. In the clock operation mode, activating the start/stop button 218 and the button 226 do not perform any function. When the button 228 is activated once, a signal 208 is sent to the microprocessor 202 to change the electronic timing circuit 200 into the stopwatch operation mode. The microprocessor 202 will then accordingly send a signal 214 to correspondingly change what the display 222 shows.

When the electronic timing circuit 200 is in the stopwatch operation mode, the display 222 will show the time that has lapsed since the stopwatch was last activated. In the scenario where the stopwatch has not yet been activated, the display 222 will show the digits "00:00:00". The display 222 is capable of displaying up to millisecond (ms) accuracy, where the lapsed time is shown in a minute, second and millisecond format, the digits representing the three fields being respectively arranged from left to right. If the stopwatch is deactivated, activating the start/stop button 218 sends a signal 210 to the microprocessor 202 to start the stopwatch. The display 222 will then receive a signal 214 from the microprocessor 202 so that the lapsed time shown on the display begins to increase as the stopwatch is running.

Starting the stopwatch also causes the microprocessor 202 to activate the LED driver circuit 206 through a signal 216. The LED driver circuit 206 will cause the LEDs 124 (Figure 1) to light up one at a time in a sequential clockwise manner beginning with the leftmost LED 124 (Figure 1), so that at any one instant only one

LED 124 (Figure 1) is emitting light. At the end of one LED 124 (Figure 1) operation sequence (i.e. after the rightmost LED 124 has emitted light), the LED 124 (Figure 1) operation sequence will repeat itself with the leftmost LED 124 (Figure 1) emitting light while the rightmost LED 124 (Figure 1) ceases light emission. The LEDs 124 (Figure 1) continue to operate as the stopwatch runs even when the electronic timing circuit 200 is switched to another operation mode, thus providing a mechanism to check whether the stopwatch is working regardless of the electronic timing circuit 200 operation mode.

Activating the start/stop button 218 again once while the stopwatch is activated causes another signal 210 to be sent to the microprocessor 202 to stop the stopwatch. The lapsed time shown on the display 222 will then accordingly stop increasing due to a signal 214 received from the microprocessor 202. The microprocessor 202 will also send a signal 214 to deactivate the LED driver circuit 206. The LEDs 124 (Figure 1) will then cease lighting.

In the stopwatch operation mode, activating the button 226 while the stopwatch is running sends a signal 212 to the microprocessor 202 that causes the display 222 to show the lap time. When the stopwatch is deactivated, activating the button 226 sends a signal 212 to the microprocessor 202 to reset the stopwatch and the display 222 will accordingly show the digits "00:00:00" due to a signal 214 received from the microprocessor 202.

Regardless of whether the stopwatch is operating, activating the button 228 once sends a signal 208 to the microprocessor 202 to switch the electronic timing circuit 200 to the alarm operation mode.

When the electronic timing circuit 200 is in the alarm operation mode, the display 222 will show a time the alarm 232 will sound and the alarm 232 activation status. The alarm time is shown in an hour and minute format, where the digits representing the two fields are respectively arranged from left to right. At the stipulated alarm time and assuming that the alarm 232 has been activated, the microprocessor 202 will send a signal 230 to cause the alarm 232 to emit a sound. While the alarm 232 is sounding, activating the start/stop button 218 once will cause

the microprocessor 202 to send another signal 230 to stop the alarm 232 from sounding but still leave the alarm 232 in its activated status. When the alarm 232 is not sounding, activating the start/stop button 218 once will change the alarm 232 activation status depending on the previous activation status of the alarm 232. If the alarm 232 was previously deactivated, activating the start/stop button 218 once activates the alarm 232. On the other hand, if the alarm 232 was previously activated, activating the start/stop button 218 once deactivates the alarm 232.

In the alarm operation mode, activating the button 228 once will send a signal 208 to the microprocessor 202 to change the electronic timing circuit 200 into the clock setting operation mode. The microprocessor 202 will then accordingly send a signal 214 to correspondingly change the display 222 to the clock setting operation mode, which is of a similar display format to the clock operation mode described earlier. Thus, in the clock setting operation mode the display 222 will show time in an hour, minute and second format, where the digits representing the three fields are respectively arranged from left to right.

The clock setting operation mode allows a user to adjust the time and date fields shown on the display 222. Each activation of the button 226 will send a signal 208 to the microprocessor 208 to select a field for adjustment from a sequence beginning with the hour field, the minute field, the second field, the day field, the month field and finally the morning (am) or afternoon (pm) field. At the point where the am or pm field is selected, activating the button 226 one more time will repeat the entire sequence. The field that has been selected will blink at a particular frequency. Activating the start/stop button 218 at each selected field will cause the microprocessor 202 to send a signal 214 to the display 222 and increment the field value shown. For example, when the hour field has been selected, each activation of the start/stop button 218 will increment the digit representing the hour field by one. On the other hand, activating the button 228 will return the electronic timing circuit 200 to the clock operation mode.

Returning to the alarm operation mode, activating the button 226 once will send a signal 208 to the microprocessor 202 to change the electronic timing circuit 200 into the alarm setting operation mode. The microprocessor 202 will then accordingly send a signal 214 to correspondingly change the display 222 to the alarm setting

operation mode, which is of a similar display format to the alarm operation mode described earlier. Thus, in the alarm setting operation mode, the display 222 will show the alarm time in an hour and minute format, where the digits representing the two fields are respectively arranged from left to right.

The alarm setting operation mode allows a user to adjust the hour and minute fields shown on the display 222. The first activation of the button 226 will send a signal 208 to the microprocessor 208 to select the hour field, while the second activation of the button 226 will send a signal 208 to the microprocessor 208 to select the minute field. The third activation of the button 226 will send a signal 208 to the microprocessor 208 to return the electronic timing circuit 200 to the alarm operation mode. The field that has been selected will blink at a particular frequency. Activating the start/stop button 218 at each selected field will cause the microprocessor 202 to send a signal 214 to the display 222 and increment the field value shown. For example, when the hour field has been selected, each activation of the start/stop button 218 will increment the digit representing the hour field by one. On the other hand, activating the button 228 will switch the electronic timing circuit 200 to the clock operation mode.

Turning to the electric port 240 connected to the display 222, the electric port 240 allows for an external display unit (not shown) to be coupled to the electronic timing circuit 200. In this manner, the contents of the display 222 can be shown on the external display unit.

Figure 3 shows one electrical schematic 300 of the LED driver circuit 206 of Figure 2.

The electrical schematic 300 comprises a driver integrated circuit (IC) chip 302, 5 LEDs 304, a power source 204 and a switch 310. The reference numeral 304 is an electronic block representation of the LED 124 shown in Figure 1.

The IC chip 302 used is model no. "SC 188-66 E/F/G/H/l" from "Rui Da". The IC chip 302 comprises 6 output ports L1 - L6, oscillator input ports OSCO and OSC1 , voltage input ports VSS and VDD ₁ input ports OFFB, OS, RD/SQ and ON/OFF. A 3V

power supply is required to power the IC chip 302. The IC chip 302 has a standby current of around 5μA and an operating current of around 400μA.

Each of the output ports L1 - L5 is connected to one LED 304, while the remaining output port L6 is not used. The LED 304 connected to the output port L1 corresponds to the leftmost LED 124 (Figure 1) while the LED 304 connected to the output port L5 corresponds to the rightmost LED 124 (Figure 1). The oscillator input ports OSCO and OSC1 , which provide a mechanism to modulate the operating frequency of the IC chip 302, are not used, thus leaving the IC chip 302 to operate at a built in frequency of 1 Hz. The input ports OFFB and OS are not used, while the remaining input port RD/SQ is electrically grounded 308 and input port ON/OFF is electrically grounded 308 through the switch 310.

The switch 310 acts as control to activate or deactivate the LEDs 304. The operation of the switch is controlled via the signal 216 (Figure 2) from the microprocessor 202 (Figure 2) and has already been described with reference to Figure 2.

Connecting the input port RD/SQ to the ground has the effect of causing the IC chip 302 to activate the LEDs 304 in a sequential manner beginning with the LED 304 connected to output port L1 and ending with the LED 304 connected to output port L5, so that at any one instant only one LED 304 is emitting light. At the end of the LED 304 operation sequence (i.e. after the LED 304 connected to output port L5 has emitted light), the LED 304 operation sequence will repeat itself with the LED 304 connected to the output port L1 reemitting light while the LED 304 connected to the output port L5 ceases light emission. Thus, a user will observe that each LED 124 (Figure 1) operating cycle of the timer device 100 (Figure 1) begins with the leftmost LED 124 (Figure 1) and ends with the rightmost LED 124 (Figure 1) wherein at any one instance, only one LED 124 (Figure 1) is emitting light.

The LEDs 304 are connected to the power source 306. The LED 304 has a sink current of around 20 mA and requires a 3V power supply to operate. A typical LED that can be used is model number no. "5003R1 C-BSA-A" from "HuiYuan Optoelectronic Co., LTD"

The power supply 204 is two portable button cell type batteries that each have a voltage supply rating of 1.5V connected in series so as to produce a total voltage supply rating of 3V. A typical power supply 204 is model no. "LR41 (192)" from "Sony".

Figure 4 shows an exploded perspective view 400 of components that comprise the timer device 100 of Figure 1. The same reference numerals used in Figures 1 and 4 indicate the same components being used in both the figures.

The display 122 is elevated a small distance from a printed circuit board (PCB) 406 through spacers 408 and 410. The printed circuit board (PCB) 406 comprises electrical access points for the start/stop button 1 18, the LEDs 124, the display 122, the buttons 126 and 128 so that the electronic timing circuit 200 (Figure 2) is formed on the PCB 406. A space 402 within the bottom surface structure 116 is provided to contain the PCB 406 when the timer device 100 is assembled.

The timer device 100 can be placed in a holder 404 after the timer device 100 is assembled, the holder 404 being made of a flexibly resilient material such as rubber. The holder 404 has a recess 416 with a side wall 412 that snugly engages the outer wall of the bottom surface structure 116. The holder 404 also has a flange that extends around the top of the side wall 412 so that the flange engages the top surface structure 112 when the timer device 100 is placed into the holder 404. The holder 404 has a suction type base 414 that frictionally attaches to a flat surface so that the timer device 100 does not readily shift when the start/stop button 118 or the buttons 126 and 128 are depressed. This frictionally attachment is advantageous especially in games, such as cup stacking, where precision timing from the commencement to the end of the game is required and the shifting of a timer during the timer operation may result in an inaccurate game time measurement. Further the frictional attachment makes it easier for a user to operate the timer device 100 without assistance and therefore measure the time taken to complete a game such as cup stacking.

The suction type base 414 has a diameter of around 60mm, while the holder 404 has a top diameter of around 70mm. The height of the holder is around

30.5mm and with the timer device 100 placed in the holder, the height of the resulting product 500 shown in Figure 5 becomes around 31.7mm.

Figure 6 shows a top view of a timer device 600 built in accordance to an alternative embodiment of the present invention.

The timer device 600 is structurally similar to the timer device 100 of Figure 1A. For the timer device 600, buttons 628 and 626 have the same respective functionality as the buttons 128 and 126 of the timer device 100 of Figure 1A.

Importantly, in the timer device 600, a display 622 is disposed in a start/stop button 618. The start/stop button 618 extends substantially between two opposing edge portions 620 and 620' of the top surface structure of the timer device 600. The start/stop button 618 has a truncated circular shape, where the edge of the circular portion of the start/stop button 618 lies along the majority of an inner perimeter of the top surface of the timer device 600.

One or more LEDs 624 are disposed on the start/stop button 618. The one or more LEDs 624 are located along a portion of the perimeter of the start/stop button 618.

The start/stop button 618 is spring biased at one or more support elements 630 at the bottom of the start/stop button 618, so that the start/stop button protrudes the rim 631 of the housing 610 when the start/stop button 618 is not depressed. In addition, the one or more support elements 618 have a hollow centre (not shown) that allows wires from the display 622 and the LEDs 124 to pass through and connect to an electronic timing circuit within the housing 610.

It will be appreciated by a person skilled in the art that numerous variations and/or modifications may be made to the present invention as shown in the specific embodiments without departing from the spirit or scope of the invention as broadly described. The present embodiments are, therefore, to be considered in all respects to be illustrative and not restrictive.

While the shape of the timer devices 100, 600 have been described as being circular and having the dimensions outlined above, it will be appreciated that the timer device can be of other shapes, including, but not limited to, rectangular, square, ellipsoid, and triangular and having other dimensions.

Similarly, while the shape of the start/stop buttons 118, 618 have been described as being similar to a truncated circle and having the dimensions outlined above, it will be appreciated that the start/stop buttons 118, 618 can be of other shapes, including, but not limited to, rectangular, square, ellipsoid, and triangular and having other dimensions.
