Abstract

A wrist-carried radiotelephone, operable without removing from a user'"'"'s wrist, includes a housing including a display and a battery, and a wristband having a plurality of rigid and flexing portions. The flexing portions mechanically connect the rigid portions. The wristband is electrically and mechanically coupled to the housing. The radiotelephone circuitry is distributed within the rigid portions of the wristband and is interconnected through the flexing portions of the wristband. The circuitry is coupled to the display and the battery through the wristband.

Claims

1. A wrist-carried radiotelephone operable without removing from a user'"'"'s wrist, comprising:

a detachable housing including a display and a battery, the housing, display and battery being detachable without removing the wrist-carried radiotelephone from the user'"'"'s wrist;

a wristband having rigid and flexing portions, the flexing portions mechanically connecting the rigid portions, the wristband being mechanically coupled to the housing;

radiotelephone circuitry distributed within the wristband, the radiotelephone circuitry including circuit boards electrically interconnected by flexible interconnects contained within the rigid portions of the wristband, the circuitry being coupled to the display and the battery through the detachable housing; and

a deployable antenna assembly that is mechanically coupled to the wristband on both sides of the detachable housing such that the antenna deploys in proximity to the detachable housing, the antenna is stowed in at least one rigid portion of the wristband on either side of the housing when not in use, and wherein when operating the radiotelephone the antenna is deployed out of the at least one rigid portion of the wristband such that the antenna assembly extends over the detachable housing.

2. The wrist-carried radiotelephone according to claim 1, further comprising a speaker, a microphone, and a clasp to mechanically connect ends of the wristband together, wherein the clasp also contains electrical user interface circuits coupled to the radiotelephone circuitry, the user interface circuits including at least one of a microphone, an interface jack, a battery charging jack, and a subscriber identification module (SIM) chip.

3. The wrist-carried radiotelephone according to claim 1, further comprising an extendable earpiece containing an electromechanical transducer disposed therein, the earpiece being electrically and mechanically coupled to the wrist-carried radiotelephone via a retractable electrical cord, the extendable earpiece is configured to be positioned between two fingers of the user such that the earpiece is located on a palm side of the user'"'"'s hand and can be held up to the users ear.

4. The wrist-carried radiotelephone according to claim 1, further comprising an extendable earpiece containing an electromechanical transducer disposed therein, the earpiece being electrically coupled to the wrist-carried radiotelephone, wherein the earpiece is operable in a position from one of the group of:

being held via a retractable electrical cord at an end of the fingers and in proximity to an ear of the user, and being worn as a wireless ring adapted to be held in proximity to the ear of the user.

5. The wrist-carried radiotelephone according to claim 1, further comprising a remote earpiece, wherein the remote earpiece is electrically coupled to the radiotelephone via one of an infrared and radio frequency wireless link.

6. The wrist-carried radiotelephone according to claim 5, wherein the remote earpiece includes a separate battery and the radiotelephone includes a charging cradle to electrically and mechanically couple to the remote earpiece when not in use so as to charge the secondary battery from the radiotelephone battery so as to allow charging of the separate battery while the radiotelephone is still in use.

7. The wrist-carried radiotelephone according to claim 1, wherein the rigid portions of the wristband are of metal so as to shield the circuitry, and the circuitry on the printed circuit boards are insulated with standoffs from the rigid portions.

8. The wrist-carried radiotelephone according to claim 1, wherein the antenna includes a configuration including one of the group of an extended loop, a collapsed loop, an extended monopole, a collapsed monopole, an extended dipole, and a collapsed dipole.

9. The wrist-carried radiotelephone according to claim 1, wherein the radiotelephone is actuated to answer an incoming call when the earpiece is removed from its cradle on the wristband.

10. A wrist-carried radiotelephone operable without removing from a user'"'"'s wrist, comprising:

a detachable housing including a display and a removable battery, the housing, display and battery being detachable without removing the wrist-carried radiotelephone from the user'"'"'s wrist;

a wristband having rigid and flexing portions, the rigid portions of the wristband are of metal so as to provide a shield for electronic circuitry the wristband being mechanically coupled to the housing;

a wired earpiece containing an electromechanical transducer disposed therein, wherein upon removal of the earpiece from a cradle on the radiotelephone causes the radiotelephone to answer an incoming call and replacing the earpiece in the cradle serves to disconnect the call;

a clasp for mechanically connecting ends of the wristband together, the clasp containing a microphone; and

radiotelephone circuitry distributed within the rigid portions of the wristband and electrically insulated therefrom, the radiotelephone circuitry including circuit boards electrically interconnected by flexible interconnects contained within the rigid portions of the wristband, the circuitry being coupled to the display and the battery through the detachable housing and to the microphone through the clasp.

11. The wrist-carried radiotelephone according to claim 10, wherein the clasp also contains electrical user interface circuits coupled to the radiotelephone circuitry, the user interface circuits including at least one of an interface jack, a battery charging jack, and a subscriber identification module (SIM) chip.

12. The wrist-carried radiotelephone according to claim 10, further comprising a deployable antenna assembly that is mechanically coupled to the wristband on both sides of the detachable housing such that the antenna deploys in proximity to the detachable housing, the antenna is stowed in at least one rigid portion of the wristband on either side of the housing when not in use, and wherein when operating the radiotelephone the antenna is deployed out of the at least one rigid portion of the wristband such that the antenna assembly extends over the detachable housing.

13. The wrist-carried radiotelephone according to claim 12, wherein the antenna includes a configuration including one of the group of an extended loop, a collapsed loop, an extended monopole, a collapsed monopole, an extended dipole, and a collapsed dipole.

14. A wrist-carried radiotelephone operable without removing from a user'"'"'s wrist, comprising:

a detachable housing including a display and a removable battery, the housing, display and battery being detachable without removing the wrist-carried radiotelephone from the user'"'"'s wrist;

a wristband having rigid and flexing portions, the rigid portions of the wristband are of metal so as to provide a shield for electronic circuitry the wristband being mechanically coupled to the housing;

an earpiece containing an electromechanical transducer disposed therein, wherein upon removal of the earpiece from a cradle on the radiotelephone causes the radiotelephone to answer an incoming call and replacing the earpiece in the cradle serves to disconnect the call;

a charging cradle on radiotelephone, the charging cradle for electrically and mechanically coupling to the remote earpiece when not in use so as to charge the secondary battery from the battery so as to allow charging of the separate battery while the radiotelephone is still in use;

a clasp for mechanically connecting ends of the wristband together, the clasp containing electrical user interface circuits coupled to the radiotelephone circuitry, the user interface circuits including at least one of a microphone, an interface jack, a battery charging jack, and a subscriber identification module (SIM) chip;
