Abstract: An AM/FM radio receiver is integrated with a wireless phone unit. Preferably, a wireless headset communicates with the integrated unit to selectively provide both commercial radio audio and wireless telephony. A microphone unit allows the user to conduct a wireless telephone call from the headset.

Abstract: A headset for wireless communicating with a personal electronic device, such as a wireless phone, provides audio output based on an audio signal from the personal electronic device. A secondary battery in the headset provides power for the headset and is rechargeable from a primary battery in the personal electronic device, thereby allowing the user to recharge the headset in the field. Alternatively two secondary batteries may be provided. One of the secondary batteries can be used to power the headset, while the other is connected to the personal electronic device for recharging from the primary battery. When the battery in the headset becomes depleted, the batteries are exchanged.

Abstract: A personal electronic device, such as a wireless phone or personal digital assistant is separable from its primary battery when it is to be used. A smaller secondary battery within the device provides power during individual uses of the device. The secondary battery is recharged by the primary battery when the device is reconnected to the primary battery. Consequently, the device is lighter and less bulky when in use due to the absence of the primary battery unit. A belt clip is disposed on the primary battery unit so as to retain the primary battery unit on the user's belt or elsewhere when the device is separated. The separable portion of the device is releasably latched to the primary battery unit so as to be secured in place when not in use.

Abstract: A headset can be used to listen to music or other audio programming and can also be used conduct a telephone conversation. A microphone on a biased arm pivots between an extended position and a retracted position so as to be in place for conducting a telephone call, but out of the way when not in use. Extension of the microphone arm may signal the acceptance of an incoming call or may initiate a call being placed by the user.

Abstract: A headset case for a wireless headset allows the headset to be coiled for safe storage and convenient transport. A circuitry cabinet of the headset is secured to a rotating spool that is then rotated to wind up wired connections between the cabinet and the headphones of the headset. Finally, the headphones are secured on the case. Preferably, the case is integrated into an audio or telephone unit with which the headset is used.

Abstract: A portable radio transceiver selectively transmits and/or receives RF signals in two frequency bands and in two modes of operation. The radio transceiver selectively switches between two antennas for operating in either of the two modes, such as a handheld mode of operation using the transceiver's on-board antenna and battery, or a car mode of operation using an external antenna and battery. Either antenna can transmit and/or receive RF signals in the two frequency bands, such as PCS and cellular, for example.

Abstract: A remote receiving system and apparatus for alerting a mobile communications device user of an incoming call. The remote receiving apparatus is portable and receives a coded radiofrequency signal, including a first preselected identification code, transmitted from the mobile communications device, such transmission occurring upon receipt of the incoming call in the mobile communications device.
