Title:
HYBRID ANALOG WATCH
Document Type and Number:
WIPO Patent Application WO/2017/088612
Kind Code:
A1
Abstract:
An analog watch (10) has a casing (30) and a watch dial (42) supported by the casing (30). The casing (30) has indicia thereon comprising numerals and index hour markers (43) arranged in consecutive order so as to represent time in hours and minutes. The analog watch (10) has a concentric shaft device comprising a plurality of concentrically arranged shafts (80, 81, 82). The analog watch (10) includes an hour hand (38) connected to one of the shafts (80, 81, 82) such that the hour hand (38) can rotate over the watch dial (42), a first stepper motor (102) to drive the shaft (80) to which the hour hand (38) is connected, a minute hand (39) connected to one of the shafts (80, 81, 82) such that the minute hand (39) can rotate over the watch dial (42), a second stepper motor (104) to drive the shaft (81) to which the minute hand (39) is connected, a multi-function hand (40) connected to one of the shafts (80, 81, 82) such that the multi-function hand (40) can rotate over the watch dial (42), and a third stepper motor (106) to drive the shaft (82) to which the multi-function hand (40) is connected. The analog watch (10) has a microcontroller (100) having a plurality inputs and outputs, a Real Time Clock, a memory, a digital signal processor and CPU. The microcontroller (100) outputs separate control signals to control the first, second and third stepper motors (102, 104, 106) so as to control movement of the hour hand (38), minute hand (39) and multi-function hand (40). The analog watch (10) includes a Bluetooth circuit (16) in electronic signal communication with the microcontroller (100). The Bluetooth circuit (16) is configured to be discovered by and paired with a Bluetooth communication device (12) so as to create a Bluetooth communication link that enables the Bluetooth circuit (16) to receive RF signals (20) from the Bluetooth communication device (12). The Bluetooth circuit (16) converts the received RF signals (20) into digital signals for input to the microcontroller (100). The digital signals define the date and time in a present time zone and a desired mode of operation of the analog watch (10) that defines the function of the multi-function hand (40). The microcontroller (100) processes the digital signals to adjust or set the Real Time Clock to the current date and time and to control the movement of the hour and minute hands (38, 39) in accordance with the Real Time Clock and to control the movement of the multi-function hand (40) in accordance with the desired mode of operation.
