  • Patent number: 6678374
    Abstract: Activating a switch by a handset where the switch is manually activated when the user wishes to answer an incoming call. While the switch is in the deactivated state, the handset transmits to a sound card within a personal computer a multi-frequency tone which is detectable by the sound card. When the manual switch is activated, the handset ceases to transmit the multi-frequency tone to the sound card. The sound card detects the absence of the multi-frequency tone to determine if the handset is answering a call. In traditional telephony terms, when the manual switch is activated, this is the offhook condition. When the manual switch is deactivated, this is the onhook condition . When the user is done with the call and deactivates the manual switch, the handset again generates the multi-frequency tone that is subsequently detected by the software via the sound card. Then, the software knows to signal the other party on the call that the call has been terminated.

A sound card within a personal computer transmits a hook tone that is above the human hearing range to a transmitter section of the handset. When the switch is in the activated state, the handset re-transmits the hook tone back to the sound card which converts the hook tone to digital information so that the hook tone can be detected by software running in the personal computer. When the manual switch is deactivated, the handset ceases to re-transmit the hook tone back to the sound card. The software detects the absence of the hook tone to determine if the handset is answering the incoming call.

    Abstract: A communications station for use in a distributed audio system having two Hall-effect integrated circuits mounted on a printed circuit hook switch board, the hook switch board mounted within a handset cradle of the communications station. The Hall-effect integrated circuits place the communications station on-hook or off-hook, depending on the amount of ambient magnetic flux. The ambient magnetic flux varies with the presence or absence of a handset in the cradle. Thus, if a handset containing a magnet is in the cradle, and the applied magnetic flux is greater than the predetermined flux necessary to affect the Hall-effect integrated circuit, the communications station will go on-hook. When the handset and the resultant flux is removed from the cradle, the Hall-effect integrated circuit will change state and the communications station will go off-hook.

  • Patent number: 6052573
    Abstract: An off-hook/on-hook signal discriminating means 5a is provided in a control portion 5 of the FSU in order to make discrimination between a pulse dial signal and a hooking signal. When a telephone turns to an off-hook state after an on-hook state and turns to an on-hook state again and the on-hook state is continued for a predetermined time, the FSU performs a terminating process so as to be returned into a standby state. When an off-hook signal is detected again in a time smaller than a predetermined time, the FSU recognizes that the signal is either a dial pulse signal or a hooking signal, and the off-hook/on-hook signal discriminating means 5a monitors the time required for detecting an on-hook signal again. When the time required for detecting an on-hook signal again is smaller than the predetermined time, the FSU decides that the signal is a dial pulse signal, and controls a tone generating circuit 7f to stop the dial tone.

    Abstract: Hook conditions of a handset of a telephone apparatus which includes a telephone apparatus base having an inside and an outside are sensed by providing a beam of radiation outside of that telephone apparatus base. The handset is placed in that beam of radiation outside the telephone apparatus base in an on-hook condition of that handset on the telephone apparatus base. An off-hook condition of the handset is signaled by removing that handset from that beam of radiation while removing such handset from the telephone apparatus base. A method of preventing eavesdropping through microphone and earphone of a handset of a telephone apparatus opens a circuit of either the microphone or the earphone and short-circuits either the earphone or the microphone, respectively while the handset is on-hook on a base of that telephone.

  • Patent number: 5086452
    Abstract: A mobile unit is normally disposed in a predetermined positional relationship with a base unit connected to a wired line. For example, the mobile unit is mounted on the mobile-unit receiving part of the base unit. If the predetermined positional relationship is changed, it is detected by means of a detector such as a electrical, mechanical, or optical detector. In response to the detection of a change in the predetermined positional relationship, a radio link may be established between the base unit and the mobile unit or a communication link may be established between the mobile unit and a calling party. Furthermore, in response to the detection of the change, the mobile unit or the base unit may be partly or entirely powered so as to establish the radio link or the communication link. When the mobile unit is reset to a position in the predetermined positional relationship, it is detected by the detector.
