  • Voltage supply circuitry and integrated circuit therefor
    Patent number: 8750533
    Abstract: A voltage supply circuitry is capable of coupling to wired audio headset circuitry and configurable to operate in a first mode, wherein the voltage supply circuitry provides a voltage supply to the wired audio headset functionality circuitry. The voltage supply circuitry is further capable of coupling to visual indication circuitry and further configurable to operate in a second mode, wherein the voltage supply circuitry provides a voltage supply to the visual indication circuitry.

  • Radiotelephone controller configured for coresident secure and nonsecure modes
    Patent number: 5060264
    Abstract: A controller for a radiotelephone having the capability of operation in both a secure mode for call authorization and a nonsecure mode for user interface is disclosed. The nonsecure mode and secure mode of operation are both resident in a single microcontroller which runs the nonsecure operations until a requirement for the secure operation is requested during call placement. The nonsecure mode is disabled during the period of time the secure mode is operational and is reenabled upon completion of the secure mode operation. The secure mode cannot be accessed externally to the microcontroller.
