Title: A filter and system incorporating the filter for processing discrete samples of composite signals
IPC: H04N9/888
Filed: 1980-11-10
Abstract: A system for processing discrete digitized samples (at a frequency nfc, eg 3fc) representing composite signals utilizing a comb filter which eliminates a periodic signal component (at a frequency fc) from the composite signal. The filter receives and stores (eg by means of sample period delays 50,52,54) consecutive samples and, for each received sample provides (eg by summing the delayed samples and then division 51,53,57) a digital average representation of the values of such a number (eg 3) of the received samples that gives a zero average value of the periodic signal component. In one embodiment of the signal processing system, the filter is arranged in circuit with digital delays and digital signal combining and differencing circuits to form a digital color television signal dropout compensator, which is adaptable for use in NTSC, PAL, PAL-M, or other television standard systems. In a dropout compensator adapted for NTSC color television signals, the filter receives the digital composite television signal and eliminates the chrominance component therefrom, leaving only the luminance component at its output. A following digital subtractor is coupled to subtract the luminance component provided by the filter from the received digital composite television signal and provide the chrominance component at its output. The separated chrominance component is phase adjusted on consecutive television lines and recombined with the separated luminance component provided by the filter for substitution in the television signal in place of the dropout affected portion thereof. The dropout compensator also includes a digital delay of one horizontal line period through which the television signal components are passed to provide the delay necessary for substituting television signal information from a prior horizontal line. <IMAGE>

Title: Range finder
IPC: G01S17/14
Filed: 1981-11-02
Abstract: An electronic range finder for ascertaining the distance of a target, wherein a transmitter (2, 2') radiates an optical or acoustic transmission impulse sequence which, after reflection at the target, arrives at a reception amplifier (8) the amplification factor of which is raised in a time-dependent manner during the transmission impulse interval. Each transmission impulse switches a further impulse sequence onto an impulse counter (5) the impulse frequency of which sequence is higher than the frequency of the transmission impulse sequence. The counter state is conducted to an evaluation circuit, e.g. a display unit (11) A control circuit (6, 7) forms, from the counter state, a control quantity which embraces the square of the counter state and possibly a correction for the input voltage dependency of the amplification factor of the amplifier (8). The control quantity controls the amplification of the amplifier (8). The amplifier (8) stops, upon the receipt of an impulse, the counter (5), and upon the occurrence of a transmission impulse, the counter (5) is reset. An impulse transit-time measurement for a wide range of target distances is possible even if short transmission impulses and long transmission impulse intervals are employed. Application to proximity fuses is mentioned. <IMAGE>

Title: Automotive ignition systems
Inventor: LEHNING HEINZ
IPC: F02P3/055
Filed: 1983-03-26
Abstract: A periodic signal provided by a magnetic sensor 3 is compared with two reference potentials by means of two comparators 13 and 15. An output signal provided by one comparator 13 is used to enable the supply of current to an ignition coil 39 whilst an output signal provided by the second comparator 15 is used to switch off the current in the ignition coil. In this way the switching on and off of the flow of current through the ignition coil are made independent of one another enabling more accurate ignition timing to be obtained at all engine speeds. The coil current is regulated by a circuit including an operational amplifier 58 and the reference potential supplied to the comparator 13 is increased as the speed of the engine decreases so that the time period for which the coil current is at its maximum value is a constant proportion of the period of the sensor waveform despite changes in engine speed. To prevent malfunction of the system at low engine speeds and low supply voltage, a switch 69 controlled by a speed detector 70 and a voltage detector 75 are provided to step down the waveform Vsc supplied to the comparator 13. An over voltage protection circuit 84-90 is provided for Darlington transistors 28, 29. <IMAGE>

Title: Tuned amplifier system
Inventor: LEITCH CLIFFORD DANA
IPC: H03F1/32
Filed: 1983-03-28
Abstract: A signal processing circuit amplifies low level modulated radio frequency signals in an efficient manner which minimizes the amount of undesired splatter components generated. The envelope of the signal is derived from envelope detector 120 and clipped (130) when below a set threshold (Fig. 4c). During this dipped interval, the other channel (150,160, 170) amplifies the input signal linearly: during the non-clipped interval the channel (150,160,170) operates in e.g. class C mode. The output signal is obtained from modulating one channel with the other in modulator 180. <IMAGE>

Title: Gravity oriented perforating gun for use in slanted boreholes
Inventor: GEORGE FLINT R
IPC: E21B43/117
Filed: 1983-10-07
Abstract: The disclosure relates to a gravity oriented perforating gun (10) for use downhole in a slanted borehole (12). The center of gravity of the gun is located relative to the charge carrier (24 to 30) and to a journal means (52) to cause the charge carrier to rotate by gravity about the longitudinal axis of the gun into a predetermined relative position. A plurality of the spaced journal means (52) support the charge carrier (24 to 30) in low friction relationship relative to the wellbore. The individual shaped charges 56 gravitate into a position which orients the direction of penetration to occur in a downward direction. Accordingly, production must occur in an upward direction through the perforations and into the slanted borehole, thereby reducing flow of formation particles into the borehole. <IMAGE>

Title: Electrical heating circuits

Abstract: A heating element 29 for an electric blanket comprises a heating conductor 14 wound concentrically with a sensing conductor 22 but separated from it by a temperature- sensitive insulating layer 28, current flowing through resistor 20 in the event of overheating tripping a thermal switch 16. In the event of local overheat, however, the magnitude of the current through resistor 20 will depend on the position of the local overheat, and will be insufficient to trip switch 16 if the overheat occurs in a first portion AC of the element 29. To overcome this, the element 29 is physically arranged in doubled formation (Fig. 4) so that the unprotected length AC of conductor 14 is physically adjacent and alongside the protected length CB thereof. <IMAGE>
