A sensor for detecting acoustic energy emitted by a target is disclosed. The sensor comprises a housing including a plurality of transducers for receiving acoustic energy. The transducers are randomly deployed within a predetermined area around the housing, forming an array and a self-survey technique is utilized to determine the positions of the sensors. Beamforming techniques are utilized to analyze the acoustic energy detected by the transducers to provide the azimuth of a target and a class estimate of the target. A plurality of sensors may be utilized to provide target location, course and velocity.

Compact deployable acoustic sensor

Methods and apparatus are provided for driving a vehicle from a remote control station achieving tele-operation of the vehicle. A television sensor mounted on the vehicle provides video image information which is reduced in bandwidth by a factor of approximately 1000:1 for transmission by narrow band RF data link to a remote control station. The large bandwidth reduction is accomplished by first sampling the video output of the sensor at a reduced frame rate and then compressing the data further by standard data compression techniques. Vehicle position and attitude data which may be derived from the vehicle's on board inertial reference unit are also transmitted via narrow band data link to the control station. At the control station, the data is first reconstructed by a technique which is the complement of the compression technique, and the instantaneous position and attitude data are used to compute transform coefficients that are used by a pipeline processor to extrapolate the frame data to generate a real time video display that enables an operator to drive the vehicle by transmitting appropriate control signals to the vehicle.

Human engineered remote driving system

A monolithic integrated circuit is provided in which signals from concurrently operating information sources are each provided to a corresponding signal processing cell in an array thereof. These cells can each communicate directly with surrounding nearest neighbor cells both to and from. Each such signal processing cell is capable of being directed in parallel to perform selected signal processing operations including operations involving data from many cells. Communications between cells can be effected using charge coupled devices, and the signal processing operations in a cell can be performed by a floating gate regenerator.

Integrated cellular array parallel processor

A local area contrast enhancement scheme for a video display includes a two dimensional recursive filter to obtain a moving average of the intensity variations in all areas of the display. This moving average is subtracted from the original signal to produce a signal which contains only local variations and this latter signal is expanded to increase the display contrast. The local area contrast enhancement scheme allows low contrast details to be perceived and permits hands-off operation of the display under varying scene conditions. The recursive filter approach results in a simple implementation of the enhancement scheme with both analog and digital circuitry.
