Abstract: The present invention is a mobile asset security system that enables remote tracking and monitoring of the asset. The security system is equipped with a control and intelligence unit, a position determining device and a number of intrusion detection devices. The control and intelligence unit processes information from the position determining device with the help of an in-built virtual mapping system to obtain geographic information of the vehicle in the form of name of place, street, coordinates, etc. The control unit may be remotely configured and controlled through a built in voice recognition and DTMF tone detector. The geographic information and information regarding any violation of intrusion detection devices is converted to synthesized speech using a text to speech system. The text to speech system converts the speech to a language desired by the user. The synthesized speech is transmitted to the user's communication device over an existing communication network.

Abstract: The non-overlap clock circuit of this invention is responsive to a variable input signal for producing a first and second output signal that vary respectively with phases opposite to and the same as the input signal. The circuit comprises a NOR-gate with its first input connected to the variable signal input and its second input to the second signal output of the circuit. The output of the NOR-gate is the first signal output of the circuit. The circuit includes a first means such as an enhancement type FET having a gate and a main current path. The gate is supplied with a first output signal of the circuit and the main current path is connected between ground and the second signal output of the circuit. A second means such as a depletion type FET is also employed with its main current path connected between the variable signal input and the second signal output of the circuit. The second signal output of the circuit is thus driven by the variable input signal through the main current path of the second means.
