Title: An electro-optical detection system for reflection free underwater images from aircraft
Inventor: SUTTON PHILIP
IPC: G01S17/89
Filed: 1992-07-09
Abstract: An etectro-optical detection system for detecting objects (12) em-bedded within a partially transmitting medium comprises means (20) to receive electromagnetic radiation in two close spectral channels (28, 212): a signal channel (212) where the wavelength and bandwith of the signal channel are optimised to correspond to the peak of transmission of the medium and a reference channel (28) where the wavelength and bandwidth are selected to correspond to a spectral region where attenua-tion in the medium is high. The signal and reference channels are then subtracted (213) so as to remove the effect of reflected radiation from the signal channel (212). The signal is processed digitally (218) to provide an enhanced image of the field of view. In a particular arrangement for de-testing objects underwater a CCD TV camera (20) is used with three sep-arate CCD detector arrays providing concurrent red (R); green (G), blue (B) output signals. The green and blue signals are combined in an adjus-table ratio to provide the image signal to match the prevailing conditions of the partially transmitting sea. A notch filter is employed to cut out light in a spectral band between the signal and reference channels.

Title: Video-signal transmitting and receiving apparatus and method thereof
Inventor: SAKAMOTO NORIYA
IPC: H04N19/33
Filed: 1994-03-16
Abstract: Abstract of the Disclosure This invention provides a system capable of per-forming compatible transmitting and receiving processes, regardless of whether a TV signal on the transmission side is a high-resolution signal or a low-resolution signal or of whether the reception side is a high-resolution display unit or a low-resolution display unit.  On the transmission side, a frequency division circuit divides a high-resolution TV signal into signals in a plurality of frequency bands.  The signals in each frequency band are converted into signals of a horizon-tal and vertical low band (a low-resolution TV signal band).  The converted signals are coded by coding units, which transmit the coded signals.  On the reception side, the coded signals multiplexed on the transmission side are separated and decoded at decoding units.  A frequency synthesizing circuit restores the frequency bands of the decoded signals to the original bands. Then, the resulting signals are displayed with a high resolution.  A low-resolution signal is coded and then transmitted.  The coded signal is decoded on the recep-tion side.  The decoded signal is interpolated at an interpolation circuit.  The interpolated signal is then displayed on a high-resolution display unit.

Title: Method and apparatus for supplying synchronization signals serving as clock signals with defined phase relationships
Inventor: PITIO WALTER M
IPC: H04L7/033
Filed: 1994-12-20
Abstract: The present invention relates to a method and apparatus for recovering the time base of signals which change at periodic intervals. The apparatus comprises gated voltage controlled oscillators (GVOC) that are alternated or exchanged, to reduce phase and frequency deviations in the recovered time base signal, such as the deviations induced by inherent GVCO differences. Each GVCO is stabilized by a respective phase locked loop. The respective GVCOs are gated only in response to a chosen polarity transition in the input signal, to make the circuit more tolerant of waveform distortions. More than two GVCOs may be used to provide improved frequency drift resistance. The circuit uses resynchronization control signals, such as the time slot signal in synchronous switching systems, to indicate resynchronization or reassignment the GVCOs in gaps in the data transmission. Automatic reassignment is insured when there are periods of non-transitioning data that last longer then the stability of the GVCOs to prevent frequency drift in the recovered clock.
