Definitions

  • the present invention relates generally to wireless communication devices, and specifically to cellular telephones .
  • Portable cellular telephones have gained extremely wide acceptance.
  • One advantage of cellular telephones is that they enable a subscriber to place and receive calls at the same number, regardless of whether he cr she is at home, at the office or traveling.
  • the cradle has a connector that interfaces with a mating connector on the telephone, known in the art as a car-kit connector, so as to convey both electrical power to the telephone and two-way audio signals between the telephone and a speakerpnone system in the car.
  • desktop cradles for cellular telephones typically provide only electrical power, for the purpose of charging the telephone battery.
  • U.S. Patent 4,972,457 which is incorporated herein by reference, describes a portable hybrid communication system, which integrates a personal computer, cellular transmitter, modem, and speakerphone into a case with a facility for external connections.
  • the system has connectors for attaching a headset, cellular control unit, land telephone line, and additional speakers and microphones.
  • the system does not require or accept a user's ordinary, pocket-size cellular telephone, since the cellular transmitter is an integral part of the overall system.
  • Wireless telephones including both cellular teieohones and cordless phones, generally communicate using RF transmission and reception.
  • IR wireless phones are also known in the art, however, providing for two-way IR transmission between a wired telephone line and a telephone handset.
  • European patent application no. 558,812 which is incorporated herein by reference, describes a cordless telephone handset that is linked by a photodiode and LED to a fixed station having an IR transmitter and receiver, coupled to a conventional telephone line.
  • the fixed station is placed on a desk or mounted on a wall, while the handset can be moved around within the room.
  • IR communications in place of RF, reduces susceptibility to interference and interception of communications and also reduces the exposure of users of the telephone to potentially harmful radiation.
  • Sharp Corporation, of Japan offers the "PMC" line of cellular telephones having an IR communication port.
  • This port is designed for local, very short-range, line- of-sight communication, with a personal computer, for example. It enables the cellular telephone to be used for data communication, typically in order to download information from the computer to an organizer embedded in the telephone.
  • the telephone communicates with its cellular network exclusively by means of a conventional RF transmitter/receiver.

  • the docking station includes a cradle for the telephone, with a connector that mates with a suitable connector on the telephone, typically a car-kit connector.
  • the processing circuit of the docking station is coupled to a speakerpnone or to a headset or handset, enabling a user of the cellular telephone to use the telephone at arm's length or greater distance without having to hold or support it. The user's hands are thus freed for other activities, such as writing, and the dosage of electromagnetic radiation that the user receives is greatly reduced.

  • the cradle coupler includes an electrical connecter, which mates with a mating connector on the telephone, most preferably a car-kit connector.
  • the audio input/output device enables the user to carry on the conversation while located at a distance greater than arm' s length from the telephone.
