Abstract: Existing automatic log on/log off systems in telephone systems determine whether or not a workstation is occupied and whether calls can be directed to that workstation by determining whether or not the amplifier that provides the interface between the telephone system and the occupant's headset is plugged into the workstation. Recent headsets have included a connector in the cord between the headset and the amplifier, enabling the occupant to leave the workstation without unplugging the amplifier. However, this defeats the sensing mechanism of the existing automatic log on/log off system. A wireless telephone headset system according to the present invention replaces the existing wired amplifier and headset assembly and includes a detector for determining whether a wireless communication link exists between the headset and the amplifier, and an activator for activating the existing automatic log on/log off system in the telephone system.

Abstract: A data transfer and communication system is disclosed including a central station and a plurality of remote, relay terminals. Each relay terminal includes a data entry device such as a keypad or bar code wand. A headset is associated with each relay terminal. Circuitry is provided to permit two-way wireless communication between the headset, relay terminal and central station. The relay terminal functions to transmit substantially unprocessed voice and data signals to the central station. The central station analyzes the signals and can retransmit a response which can be displayed on the relay terminal. The relay terminals are intended to be high volume, low cost items with the more expensive computational power being located at the central station.
