Abstract: A wireless air tube headset that includes a wireless transceiver operating in a radio frequency band, which wireless receives audio signals. The headset includes an acoustic chamber with an acoustic port through to the exterior thereof, and an acoustic transducer that is electrically coupled to the transceiver, and that operates to generate acoustic signals. The acoustic transducer is aligned with the acoustic chamber to emit the acoustic signals through the acoustic port. There is an acoustic isolator disposed to attenuate extraneous acoustic signals emitted from the acoustic transducer and also to attenuate ambient noise entry into the acoustic chamber. An acoustic conduit is formed from an electrically non-conductive material, and has a first opening engaged with the acoustic port and a second opening engaged with an acoustic coupler, which has a first earpiece engagement means.

Abstract: An apparatus for communicating data, including facsimile data, via first wireless signals and second wireless signals. The apparatus includes a facsimile machine coupled to a switch, a first transceiver that converts the first wireless signals with the switch, and a second transceiver that converts the second wireless signals with the switch. The switch is selectable to a first state wherein the facsimile data is coupled between the first transceiver and the facsimile machine, and a second state wherein the facsimile data is coupled between the second transceiver and the facsimile machine, and a third state wherein the data is coupled between the first transceiver and the second transceiver.

Abstract: A digital audio file reproduction apparatus, system and method having wireless transfer capability with a remote device. The apparatus includes a memory and a controller coupled to store and recall digital audio files with the memory. A transceiver operates to transmit and receive digital audio files according to a radio protocol. An audio circuit receives audio files from the controller and outputs the audio files for analog audio reproduction. The controller responds to the receipt of an in-range radio signal by the transceiver, from the remote device, to exchange digital audio files with the remote device via the radio protocol. A memory card slot is adapted to accept plural user-replaceable memory cards. The apparatus compresses and decompresses the digital audio files, which may be according to the MP3 format. A microphone circuit provided to enable the recording and storing of voice messages.

Abstract: A cordless security system that communicates through a wireless telephone network. A wireless node, having a wireless transceiver adapted to communicate wireless signals with the wireless telephone network, and a cordless transceiver adapted to communicate cordless signals with plural cordless terminal devices enables a cordless local area network. The wireless node also includes a controller that operates to couple telephone calls between the wireless transceiver and the cordless transceiver. The controller routes cordless data packets in the cordless signals through the cordless transceiver and amongst the plural cordless terminal devices. The cordless security system includes plural cordless security sensor terminal devices that communicate cordless sensor signal encoded within a cordless data packet into the cordless local area network. A cordless security control panel terminal device communicates cordless alarm signals encoded within a cordless data packet into the cordless local area network.

Abstract: A wireless and cordless telephone node system. The system includes a node with a wireless transceiver that communicates wireless signals with a wireless network, a cordless transceiver that communicates cordless signals with multiple cordless terminal units, and one or more landline interfaces that couple metallically with the PSTN. A switch routes call between the landlines, wireless network and the multiple cordless terminals. A subscriber identity module and card interface is provided for control of wireless account user data. A variety of cordless terminals are provided that emulate conventional corded telephones, cordless telephones and wireless telephones. The wireless node is designed for both fixed and portable operation.
