The present invention discloses a temporal compressor and decompressor for sequences of images. The compressor includes an interface for receiving the sequence of images. A spatial compressor generates spatially compressed image fields from the sequence of images, a data compression decoder generates data decompressed image fields from the spatially compressed image fields, a temporal processor generates temporal processed image fields from the data decompressed image fields, a data compressor e...

Systems and methods are described to address the problem of maintaining only unique data values accessed through name-value tuple sets. A knowledgebase represents data in tuple sets where all the data across the tuples comprise unique instances for memory conservation and system performance purposes. The knowledgebase stores and maintains unique values in a data store structure and represents the values as tuples through the tuple store structure. Modules access tuples and their values through h...

An encoder for providing a conical array of temporally phased pulse beams. A pulse is inserted and continuously recirculated around an optical ring. The pulse is amplified during each circulation and a portion of the pulse is emitted at the end of each circulation. The encoder includes means for spatially separating each emitted pulse to provide a conical array of beams at a constant field angle relative to the optical axis of propagation.

A twisted nematic liquid crystal optical, temporal bandpass filter device for transmitting optical images only having the time response near a given frequency. The device is comprised of two linear dichroic polarizers with orthogonal polarities at the input and output of the device and two twisted nematic liquid crystal light valves and a relay lens between the light valves. Each of the two light valves has a different time response and has opposite rotary direction handedness of the twist withi...

A temporal spectral photometer for use in obtaining spectral and temporal information simultaneously of an ultrafast pulse of luminescent light emitted from a sample upon excitation thereof includes an excitation section and a detection section. The excitation section includes a picosecond laser for exciting the sample to emit luminescent light and imaging optics for imaging the emitted light. The detection section includes a pin hole slit through which light from the imaging optics is admitted,...

A sequence generator employing a neural network having its output coupled to at least one plurality of delay elements. The delayed outputs are fed back to an input interconnection network, wherein they contribute to the next state transition through an appropriate combination of interconnections.

A fuzzy control method of a controlled object uses control rules, having a condition part, each condition part having both a first proposition characterized by a membership function whose variable is a time and a second proposition with respect to the state of the controlled object. According to the method, inputting information with respect to the state of the controlled object is input to a fuzzy control execution circuit. The degree of confidence of the first proposition characterized by the ...

A temporal data control system that uses a hand held, mobile scrubwheel that includes two position indicators and an activation switch. As a user moves the scrubwheel about on a surface of a position sensing tablet a computer controls the movement of a cursor on a display. The computer also displays one or more temporal sequences, such as video sequences, on the display. Movement of the scrubwheel is detected by the computer allowing the user to position the cursor on a sequence to be controlled...

A method and system for providing cache memory management. The system comprises a main memory, a processor coupled to the main memory, and at least one cache memory coupled to the processor for caching of data. The at least one cache memory has at least two cache ways, each comprising a plurality of sets. Each of the plurality of sets has a bit which indicates whether one of the at least two cache ways contains non-temporal data. The processor accesses data from one of the main memory or the at ...

A video signal comprising a successive series of frames is sub-band coded to derive a plurality of groups of coefficients for each frame. Each group of coefficients comprises a spectral representation of the video content of a respective portion of the frame, which portions are spatially decorrelated relative to the corresponding portions of the immediately preceding and immediately following frames to reduce block artifacts in the reproduced image.
