Abstract

A battery pack (1), for use with a portable radio-receiving apparatus or radio-telephone such as a cellular telephone, comprising a plurality of rechargeable batteries (3) housed in a box (2) engageable with the apparatus or telephone and a call alert system (5) capable of detecting an incoming call signal and generating an alerting vibration. The call alert system (5) comprises an electronic circuit (6) generating a vibration by means of a micromotor (7) having an eccentric mass (7a). When the telephone replies to an incoming call, the electronic circuit (6) detects either an RF signal coming from the telephone or an electrical absorption signal through the batteries (3). Even if the portable telephone does not have a vibrating call alert system, the user does not need to change the telephone and buy a new one, but simply need to replace the existing battery pack.

Description

TITLE

BATTERY PACK FOR PORTABLE RADIO-PAGERS OR RADIO-TELEPHONES, IN PARTICUUR CELLULAR TELEPHONES.

DESCRIPTION

Field of the invention

The present invention relates to a battery pack for use with portable radio-receiving apparatuses or radio¬ telephones, in particular cellular telephones.

r-pg-r-T- pfion of the prior art Cellular telephones battery packs normally comprise a plurality of rechargeable batteries connected in series and housed in a slim box. On the edges of the box means for engaging with the body of the telephone set are provided for, as well as electric contacts are present for the power supply to the telephone. The latter comprises all the means for receiving and sending the calls and an incoming call alert system, which may be of various types.

A first and always present type of call alert system is a ringer, normally embodied in an alerting unit comprising a loudspeaker. Optionally, a flashing light, such as a LED, can be added with the possibility of excluding the ringer. Only in some cellular telephones a third type of call alert system is provided for, comprising a vibration generator. A call operation select button allows the user to choose the setting of the ringer, the LED and, where present, the vibrator.

The vibrating call alert system is particularly useful when the user wishes to receive the call without making noise, as well as when the user works in very noisy places and could not hear the ringer. However, most of existing cellular telephones are not provided with it and it is either not possible or convenient to modify them and add it.

Summary of the invention

Accordingly, the present invention has an object, among others, to overcome deficiencies in the prior art such as noted above.

The object of the present invention is to provide a battery pack for portable radio receiving apparatuses or radio-telephones capable of alerting of the incoming call the user of the apparatus on which it is mounted.

Another object of the invention is to provide a battery pack, capable of alerting of the incoming call the user of the apparatus on which it is mounted, without requiring any modifications or settings of the apparatus itself.

These and other objects are accomplished by the battery pack according to claim 1.

Brief description of the drawings

Further characteristics and advantages of the battery pack according to the present invention will be made more apparent in the description which follows of three of its possible embodiments, given as examples, but not limitative, with reference to the above-mentioned drawings, in which: - 3 -

— figure 1 shows a top plan view of a battery pack according to the invention;

— figure 2 shows a block diagram of the layout of the battery pack of figure 1; — figure 3 shows a block diagram of a first embodiment of the call alert system of a battery pack according to the invention;

— figure 4 shows a circuit diagram related to block diagram of figure 3. — figure 5 shows a circuit diagram of a second embodiment of the call alert system of a battery pack according to the invention.

Description of the preferred embodiments

With reference to figure 1 a battery pack 1 according to the invention comprises a slim box 2 housing a plurality of rechargeable batteries 3. These are wired to electric contacts 4 suitable to engaging with corresponding electric contacts present on the cellular telephone set (not shown) or other portable radio- receiving apparatus or telephone.

According to the invention, battery pack 1 comprises a call alert system 5 capable of detecting an incoming call signal and generating an alerting vibration. In this way, even if the portable telephone does not have a vibrating call alert system, the user does not need to change the telephone and buy a new one, but simply need to replace the existing battery pack with a battery pack as claimed in claim 1. In more detail, the call alerting system 5, as also shown in figure 2, comprises an electronic circuit 6 generating a vibration by means of a micromotor 7 having an eccentric mass 7a. Circuit 6 detects an RF signal via an LC circuit or antenna 8, provided a switch 9 is in a ON position. Antenna 8 is internal to box 2 so that other signals coming from telephones present in the nearby are prevented from activating circuit 6 and then operating micromotor 7. With reference to figures 3 and 4, a preferred Radio-Frequency detecting circuit 6 is illustrated comprising a RF detector block 10, a conditioning block 11, an ON/OFF control block 12, and a motor operating block 13. More precisely, RF detector block 10 comprises a Schottky diode, which detects the transmitting signal of the telephone when it replies to an incoming call. The transmitting signal is filtered by a condenser and is compared with a threshold value so that disturbing signals present in the environment do not cause the vibration to start. The conditioning block 11 has a first delay stage 11a of the present RF signal lib (for example about 50ms) and a second delay stage lib, four times slower than the first (for example about 200ms) at the stop of the RF signal. The ON-OFF control block allows to start or to stop the call alerting system 5 and shows the status thereof by means of a LED circuit block 14.

When the user wishes to be alerted by a vibration of the battery pack according to the invention, it is sufficient that switch 9 is set on ON position. LED 14 is lighted to show the user whether the call alerting system is ON. When there is an incoming call, motor 7 starts rotating until switch 9 is turned OFF.

According to a different embodiment of the invention, detecting circuit 6 may comprise, instead of RF detector block 10, an absorption detector block 15, as shown in figure 5. Therefore, when there is an incoming call, the telephone replies and the absorption block detects an electric absorption through batteries 3. A comparator block 16 and a delaying block 17 filter the absorption signal and, depending on the ON/OFF control block, operate motor 7 through block 13.

According to a further embodiment, not described in detail, the incoming call detector may be directly connected to the telephone ringer switch, by means of a direct electric contact like contacts 4 of figure 1. This solution, easier than the other solutions above described, needs that the telephone is modified, and therefore is to be preferred only when the battery pack is manufactured together with the telephone. In this case, however, it would be possible for the telephone set to be thinner and lighter than the existing others in which the vibrating unit is already provided for, thus exploiting the space inside the battery pack instead of the space inside the telephone set.

Notwithstanding reference has been made to a micromotor with an eccentric mass, it is obvious that whichever other vibrating device can be used instead, such as, for example, an oscillating electromagnet. The foregoing description of the specific embodiments will so fully reveal the general nature of the invention that others can, by applying current knowledge, readily modify and/or adapt for various applications such specific embodiments without undue experimentation and without departing from the generic concept, and, therefore, such adaptations and modifications should and are intended to be comprehended within the meaning and range of equivalents of the disclosed embodiments. The means and materials for carrying out various disclosed functions may take a variety of alternative forms without departing from the invention. It is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation.
