Title: Video processing system for bandwidth reduction
IPC: H04N7/12
Filed: 1982-01-18
Abstract: In a video processing system for reducing data content requirements along a transmission path 15, a movement processor 12 which includes a framestore is capable of detecting both interfield and interframe movement and uses this to manipulate the data so as to inhibit or attenuate the movement content so that the available bandwidth is not exceeded. This manipulation can also be used to provide residual movement persistence between frames and to reduce picture noise content. A processor 17 at the remote end of the transmission path can reconstitute the data to make it available at normal video rates.   <IMAGE>
Patent GB-2119089-A (GB)
Title: An adaptive filter
Inventor: GLASGOW JOHN ARTHUR
IPC: G01S7/28
Filed: 1982-03-30
Abstract: A received signal which may exhibit certain frequency variations, e.g., caused by vibrations of the Doppler shift, is detected by correlating the signal with a number of reference waveforms of different frequencies. The illustrated filter is a digital filter. The signal to be filtered, from a digitizer 5, is sampled and successive blocks of samples are entered into a correlator at 6A. Each such block is correlated in turn with a number of reference waves generated at 7 and placed in turn in the reference channel 6B of the correlator. The output of the correlator, together with information from the reference wave generator 7 and a timer 1 is passed to a phase corrector 8 which calculates, for each correlation, the phase and rate of change of phase of that component of the signal block which correlates with the appropriate reference channel. These phase and rate of change of phase values are stored, together with values denoting the degree of correlation in a signal characteristic store 9. A combiner 10 searches the information in the store 9 for correlation results, from signal block to signal block, which display phase continuity thereby filtering off the remaining information which is attributed to noise. <IMAGE>

Title: Process and apparatus for determining the colour of an oxide coated glass-to-metal sealing wire
IPC: G01N27/42
Filed: 1982-05-25
Abstract: An apparatus for determining the colour of an oxide-coated alloy wire employed in glass-to-metal seals includes a chemical retort (7) including the wire sample (21) and a standard Calomel cell (29) in electrolyte 19 with energization of the wire sample from source 5 resulting in one potential output from the Calomel cell when oxide is present and another output level when the oxide has been reduced to metal. A timer (13) provides a recording of the time required to reduce the oxide to metal and in a process for determining the said colour of the wire this measurement is compared to a graph whereon time or thickness versus ASTM F-29 standard colours for the oxide are plotted. Thus, oxide colour determination is directly effected from mechanical time or thickness recordings. <IMAGE>

Filed: 1986-05-02
Abstract: A method of and apparatus for controlling the resultant velocity of a member (4) is provided, the resultant velocity being derived by driving the member in two component directions, simultaneously. First sensor means derive a signal indicative of the resultant velocity, the derived signal being compared with a preselected reference signal to derive an error signal constituting a resultant velocity demand signal which is integrated to obtain a resultant amount of movement demand signal. The resultant amount of movement demand signal is selected from 'look-up' reference table memory means and corresponding desired values derived for the amounts of movement of the member in the two component directions. The desired values are compared with signals derived from first and second sensor means sensing the movement of the member and error signals are obtained for controlling the driving of the member in the two component directions.
