Abstract: A payload stabilizer and methods for stabilizing a payload suitable for use with video camera payloads. The support and stabilizing apparatus has a gimbal having two or more mutually perpendicular axes about which motion is generated by at least two of a pan motor, a tilt motor and a roll motor wherein the pan motor is integral to the gimbal handle and surrounds the main post. The stabilizer has a feedback system providing supplemental torques to the payload through a gimbal.

Abstract: A method and apparatus for data storage and retrieval including first and second banks of refreshable memory, such as DRAMs. The user application provides a write clock and a read clock, the read clock being independent of the write clock. FIFO buffers are provided between the user application and the memory, with the buffers providing for read data with associated addresses and write data with associated addresses. A DRAM controller system is provided including a timing generator for the DRAM controlled by an external clock. The controller system controls the buffers to enable the continuous writing of user data to one of the first and second banks at a given address, with the user address and data synchronized to the write clock, while enabling simultaneous reading of data at a user provided address from the other of the first and second banks, with the loading of read addresses and outputting of read data occurring continuously and synchronously to the read clock.

Abstract: A color television signal, digitized by a sampling clock asynchronous with respect to the television signal's horizontal synchronizing pulses, is applied to a dynamically programmable digital filter which upsamples or downsamples the received digitized television signal over short time periods in response to time-base disturbances in the signal. The user may also select a higher or lower long-term clock frequency. Resampled digital samples are applied to a FIFO memory for readout at a clock rate which follows the time-averaged horizontal frequency of the received digitized television signal, or, alternatively, at a substantially fixed clock rate, asynchronous with respect to the horizontal line frequency of the received digitized color television signal.

In one embodiment of the invention the solution also comprises buffer, corrosion inhibitor, dispersant, detackifier, thickener, and flow modifier. In another embodiment of the invention the solution also comprises corrosion inhibitor and detackifier. There is also disclosed a method for removing paint from a surface using the barrier coating of this invention.

Abstract: At the input to a video signal time base corrector, the phase error is sampled during each burst interval and is used to control the operation of an analog-to-digital convertor to compensate for phase errors at the start of each line. Progressive phase errors are predicted during each line and compensated. Any residual phase error at the start of a line is detected and applied to a phase error compensator for eliminating the residual phase error. The residual phase error and the video signal are processed through separate signal paths, and the frequency and phase characteristics of the residual phase error path are adjusted to those of the video signal path.

Abstract: Velocity errors in a video signal are sampled at scan line rate and are averaged over a selected plurality of frames to enhance the repetitive velocity errors while cancelling the random velocity errors. The resulting separated repetitive velocity errors then are subtracted from the initial combined velocity errors to provide separated random velocity errors. A repetitive error interlace technique is used to generate an improved repetitive error frequency control signal, while a second order correction technique provides a corresponding random error frequency control signal. The two frequency control signals are combined and the combined signal is used to provide compensation for the initial velocity errors.

Abstract: A digital time base corrector for correcting time base errors of the digital samples of a video signal for all the various speed modes of a reproducing apparatus. The time base corrector is configured having a small capacity memory and a large capacity memory wherein the small capacity memory is divided into a first section and a second section. The first section of the small capacity memory retimes data samples for subcarrier phase errors without losing or repeating data, while the second section of the small capacity memory retimes data for horizontal frequency error without losing or repeating data in all reproducing modes except shuttle. Further, the second section of the small capacity memory in reverse and forward shuttle retimes the data for horizontal frequency and phase errors while equalizing the data rate through the time base corrector by selectively discarding or repeating horizontal lines based on line type.

Abstract: An adaptive dropout compensator is fully digital and employs an adaptive logic circuit to detect dropout characteristics such as the extent thereof and the best available replacement data, and generates an adaptive logic decision for supplying the optimum replacement data. The circuit configuration lends itself to a switchable implementation for accommodating the various color television standards.

Abstract: A noise immunity circuit incorporates a first channel for tracking a train of periodic sync pulses and for locking a window to said pulses for rejecting spurious noise signals. A second channel senses when the sync pulses are displaced in phase and establishes a new rephased window that is in phase with the displaced sync pulses.
