RELATED PRODUCTS EQUIPPED WITH SENSOR TO WARN

ON DISTANCE FROM USER".

TECHNICAL FIELD

This invention refers to the improvement in a

cellular telephone set and related products equipped with sensor to

warn on distance from user, more specifically it relates to a

electronic means able to automatically warn the user that he/she is

away from the cellular phone set or other related equipment, which

limit of distance is set by the user or by installation encompassing a

performance area, thus preventing inconveniences caused by losing

the telephone.

BASE OF THE TECHNIQUE

In general, the use of individual and portable

equipment, such as cellular telephones, palm-tops, notebooks and

others with high market value and often containing several important

private and even confidential pieces of information is more and more

frequent.

Nowadays one single user usually owns

several of such devices, carrying them inside a bag or suitcase, and

thus making that the industry launches smaller models.

With technology in constant evolution,

although such sets are very small they have state-of-the-art

technology, such as voice operation, GPS locating chip, cellular sets

equipped with cameras, Internet access, and several other features

that turn them into real consumer dreams.

Recently we were presented with some cell

phones in which users may register data about themselves and obtain

monitored heart-beating results by means of movement sensors

(accelerometer), or even incorporated with heat flow sensors that

measure the heat produced by the user's body and skin galvanic

response sensors, and such sensors are stored in a soft and stretch

armlet connected to the phone set by wireless connection; such

location system may be incorporated of a GPS (global positioning

system) which determines the location of the user.

However, even with such evolution, which

represents added value to the device, the user still may forget his set

in several places, such as airports, hotels, taxis and even home,

business meetings and several other places, thus causing several

personal problems, because, as explained above, when one loses one

of such devices, one loses not only money, but also several data

contained therein.

BRIEF DESCRIPTION OF THE INVENTION

In view of the above, the applicant developed

this improvement for a cellular phone set and related equipment,

which may now be equipped with a sensor that warns the user when

he is away from the set, and for such the original printed circuit of

the set includes a microchip that acts as a presence sensor which

functions as an antenna receiving a number of waves that may be

radiofrequency, infrared or other means of reading performed by an

external element, preferably held by the user of the improved device,

and both the sensor and the external element recognize or "reflect"

pre-set information in their manufacture.

Such microchip or presence sensor may be of

the transponder type, which may operate with pre-set parameters that

make a constant check of the distance in meters, for instance, five

meters or an optional variation of the time away from the set, for

instance thirty seconds.

For such, the users will carry with themselves

a transmitter/receiving element that may be placed in any permanent

use object, such as a keypads, pens, watches, magnetic cards, or any

other object that allows to create constant reading/checking between

the issuing/receiving devices, that is, for instance, cellular phone

equipped with issuer (sensor) and watch equipped with receiver

(sensor).

So, each time the user exceeds the pre-set

distance or time, one of such two elements (issuer/receiver) or even

both elements simultaneously make a sound or vibration to warn the

user of such exceeded distance, making that the user quickly notices

and returns to get back his device (cellular phone, palm-top,

notebook, etc.).

Obviously, this sensor may be associated to

already existing devices, such as GPS or even associated to

automatic dialers for pre-registered phones, which may warn on the

distance from the device and even show its location by GPS tracking.

The main purpose of this invention is to avoid

that the user leaves his set in public or private places, and such

distance from the set is quickly warned, thus allowing that the user

may return to the place where he/she left the set, thus avoiding losses

and/or thefts.

DESCRIPTION OF THE DRA WINGS

To complement this description and in order

to obtain a better understanding of the characteristics of this

invention, according to a preferential practical use thereof, a set of

drawing is attached hereto in an exemplified but not limited manner,

the following is represented:

Figure 1 represents an illustrative view of a

cellular phone equipped with the distance sensor and its relation with

any object equipped with the permanent checking element;

Figure 2 shows a diagram of blocks in which

such sensors involved have their communication interrupted, thus

activating the variables of distance warning.

DETAILED DESCRIPTION OF THE INVENTION

This invention refers to a "IMPROVEMENT

IN CELLULAR TELEPHONE SET AND RELATED PRODUCTS

EQUIPPED WITH SENSOR TO WARN ON DISTANCE FROM

USER", in particular it refers to a cellular phone device (AP), or

even palm-tops, notebooks and others, the integrated circuit of which

(CI) is equipped with a sensor (1) or microchip that operates as a

presence sensor, functioning as an antenna (A) that issues or receives

radiofrequency, infrared signals (S) or any other waves that may be

permanently checked by a complementary component (P) stored

within an external element (E) which, on its turn, is permanently held

by the user (U) of the device (AP) equipped with the sensor (1); both

the sensor (1) and the external elements (E) recognize or "reflect"

pre-set information of variants entered in their programming, meter

variants (M) or time variants (T); such sensors (1) and (P) are

associated to a communications means (C) that may be a "buzzer", a

led, a vibrator or any other proper device.

The external element (E) may be, for instance,

a keypad, pen, watch, magnetic card or any other object that may

store the complementary component (P) that constantly reads/checks

with the sensor (1) of the device (AP) ₅ acting as an issuer and

receiver, that is, for instance, (figure 1) a cellular telephone (AP)

equipped with the issuer (sensor) (1) and a watch (E) equipped with

the receiver (sensor) (P).

So, each time the user gets away (X) from the

set (AP) exceeding the pre-set distance in meters or exceeding some

pre-set period of time, one of the two elements (issuer/receiver) or

even both simultaneously make sounds or vibrations to warn on such

distance, making that the user quickly notices the loss and return to

get back his device (cellular phone, palm- top, notebook, etc.).

Obviously, this sensor may be associated to

already existing GPS devices (G) or even associated to automatic

dialers (D) for pre-registered phones, thus warning the distance and

further showing its location by GPS tracking.

It is important to understand that this

invention does not limit its application to details or steps described

herein. It may be applied to other classes and be used or executed in

several modes, being understood that the words used herein have as

purpose to describe not to limit.
