Abstract: A swiveling, tilting mobile telephone mounting pedestal is disclosed. This improved mounting pedestal allows a mobile telephone to be mounted conveniently and easily in a vehicle and includes a removable telephone mounting adapter plate so that one of a number of adapter plates may be used if desired. These adapter plates allow for easy mounting and removal of the telephone instrument of any mobile telephone manufacturer. The telephone pedestal provides a pivoting articulated telephone mounting arm quickly adjustable to suit the individual preferences of a number of users within a given vehicle. The pedestal includes a base portion which is typically secured to the vehicle within easy reach of the users. Locking devices on the base and the articulated arm permit adjustment of the telephone instrument to an infinite number of positions.

Abstract: The detector circuit disclosed comprises a semiconductor diode bridge providing full wave output through an operational amplifier. The amplifier is enclosed within a feedback loop in which is interposed at least one diode matched to the detector diodes so as to enhance the linearity of operation of the detector-amplifier combination over a range of operating temperature and input signal levels.

Abstract: This disclosure is directed to an Automatic Gain Control (AGC) circuit wherein the AGC loop which generates the gain control signal is separate from and not closed through the amplifier whose gain is controlled. Such arrangement permits design of the AGC loop to follow a sampled data reference signal and yet have a response time much shorter than the period between samples.
