摘要： TV camera signals to be presented on a TV monitor are processed to remove undesirable shading components. The circuitry is adaptive in that for each input video signal a low frequency component is extracted to obtain a corrective waveform which is subtracted from that input signal or a subsequent input signal to reduce or eliminate the shading component. Further correction may also be made by utilizing the corrective waveform to govern the amplification of the video signal to be displayed.

摘要： A method and apparatus for recording on recording media, having a predetermined bandwidth, composite video signals including video, blanking and synchronizing portions and having a predetermined frequency spectrum wherein the composite video signals are frequency modulated on a carrier frequency which has a value near to the upper frequency limit of the predetermined frequency spectrum so that the blanking portion of the composite video signal produces the carrier frequency, modulated signals of frequencies lower than the carrier frequency extending into the predetermined frequency spectrum are produced in response to the synchronizing portion and modulated signals having frequencies higher than the carrier frequency are produced in response to the video portion, with the maximum deviation of the carrier frequency being greater than the predetermined frequency spectrum.

摘要： A magnetic domain bubble counter includes closed-end counting loops formed by domain propagating patterns having different numbers of pattern cells. Each cycle of rotation of a magnetic drive field is counted by advancing the magnetic domains to an adjacent cell position in each loop. Each encoded count of the counter is established, by the different domain positions within the loops. The maximum count of the counter is equal to the product of the sums of the pattern cells included in all of the loops. In one preferred form, the counted drive field rotations are produced by a rotatable meter movement to accumulate counts representing the consumption of a quantity to be measured.

摘要： A frequency demodulator for demodulating FM signals in direct and complementary form wherein a pair of switching devices, such as transistors ro similar devices are switched to opposite conductivity states in response to the FM signals and wherein a delay line is connected between output terminals of the devices so that when one of the devices is switched to its nonconductive state a voltage is propagated from the output terminal through the delay line and reflected out of phase by the substantially zero impedance of the conductive device back through the delay line, so that, after a time delay of substantially twice the delay of the delay line, the voltage at the output terminal of the nonconductive device is substantially zero. The output voltage generated at the output electrode of each of the devices is thus a series of pulses at the frequency of the FM signals and having a constant pulse width of substantially twice the time delay of the delay line.

摘要： Periodic signals, for example sonar returns, to be displayed on a conventional television monitor are sampled and put into storage registers at a first rate. The storage registers are emptied at a second rate and the information is placed onto a video magnetic disk. For each sonar transmission a number of samples of the return signal are placed into, and read out of, the storage registers, during each revolution of the disk, as the return is coming in, to build up a television display signal indicative of the sonar return.
