  • Patent number: 5812206
    Abstract: A broadcast receiver is disclosed which separates 16-bit binary program labels from a transmitted television signal and applies the television signal to a recorder. The viewer enters, via a keyboard, short program labels which up to three decimal digits in length. These entered short labels are then converted into 16-bit binary program codes by a mapping function processor. Each of the 16-bit codes differs in at least two binary positions from any other 16-bit codes. These codes are stored and compared with received codes and when they agree the video recorder is controlled so as to record the TV signal. Thus, the viewer does not have to enter long codes but can use short labels to identify the programs. The short labels can be obtained by the viewer from a printed TV listing.

  • Patent number: 5678926
    Abstract: A thermocouple probe 10 suitable for use in a gas turbine engine comprises a thermocouple element 12 which is coaxially arranged inside a protective sheath 16. The thermocouple element 12 is resiliently supported by a helical member 18 which insulates the element 12 from deleterious vibrations induced in the sheath 16. In use, the thermocouple probe 10 projects through an aperture 30 in the casing 32 of a gas chamber 34. Vibrations in the probe 10 are further reduced by ensuring that the longitudinal axis AA of the probe is angularly offset from the central axis BB of the aperture 30, such that the outer periphery of the sheath 16 is in contact with the inner periphery of the aperture 30 in two diametrically opposite and axially offset locations.

  • Patent number: 5640210
    Abstract: High definition television coder/decoder a high definition coder or decoder includes a number of parallel sub-decoders or coders. The image to be coded or decoded is divided into a number of stripes, a given stripe being coded or decoded by a single sub-coder or sub-decoder. Every N.sup.th stripe is coded or decoded by the same sub-coder/sub-decoder, where N is the number of sub-coders or sub-decoders. The number of sub-coders is independent of the number of sub-decoders whereby a reduction in the number of sub-coders with increasing bit-rate capacity does not necessitate a change in decoder.

  • Patent number: 5495294
    Abstract: A synchronizing signal separator receives synchronizing signals from a remote source. A window generator opens a window for a period and a counter regenerates synchronizing signals detected when the window is open. Detection of an incoming synchronizing signal when the window is open causes a window counter to be stopped to reduce the window duration to approach a set minimum width. The window generator and the counter are controlled by a voltage controlled oscillator whose oscillation frequency varies according to a feedback signal derived from the sense of the phase error between an external counter of the window generator and the regeneration counter.

  • Patent number: 5452444
    Abstract: A method for handling data in a plurality of data storage disks having user data sectors and corresponding parity sectors, the method being used when the disks are being operated in a non-degraded or a degraded mode wherein a non-volatile RAM is used in an array control processor which controls the operation of such disks. When new data is to be written into the array, the non-volatile RAM stores information identifying the array, the starting sector into which data is to be written and the number of sectors to be used for writing the new data so that parity and data entries in corresponding sectors can be matched when a power failure occurs. Further, when opening a new array, the data and parity entries in corresponding sectors can be matched and verified, the operation for such matching being performed in between other operations that are being performed by the control processors (i.e., in the "background" thereof).

  • Patent number: 5431315
    Abstract: An apparatus for coating the surface of a substrate with a coating material, which apparatus includes a chamber into which the material is supplied in a pressurized molten state from a source thereof. The molten material is subjected to vibrations within the chamber and is forced out of the chamber through one or more orifices so that the vibration breaks up the molten material exiting from the orifices into uniform sized droplets. A charging plate places a charge on each of the droplets and supplies the charged droplets via one or more corresponding orifices in the charging plate for use in coating the substrate. The charging of the droplets maintains the uniform size of the droplets as they are applied to the substrate. The droplets are further maintained in an oxygen-free atmosphere as they pass from the chamber to and through the charging plate. Each of the components of the apparatus is made as a separate module so that the overall apparatus can be readily assembled and disassembled.

  • Patent number: 5418547
    Abstract: A matrix-type display device capable of effecting color-displaying is constructed such that the mode of sampling neighboring RGB data can be optionally selected from two modes, e.g., three-point successive sampling mode and three-point simultaneous sampling mode. In the case of the three-point successive sampling mode, since pulses are generated successively so that each pulse is shifted by one-dot term .tau. from one another, the pulse terms of sampling pulses are shifted by one-dot term .tau. from one another. Accordingly, pixel signals supplied to respective three neighboring RGB pixels are shifted by one-pixel equivalent. On the other hand, in the case of the three-point simultaneous sampling, generated pulses all stay at high level at any time. Therefore, the pulse terms of sampling pulses are made coincident, so that pixel signals supplied to respective three neighboring RGB pixels are of data on an identical point.

  • Patent number: 5414409
    Abstract: A processor, such as a microprocessor, responds to the detection of an input audio signal generated by glass breakage to cause an alarm to be indicated, such as at a remotely located alarm control panel. The system determines when the input power supply voltage supplied to the system falls below a selected low voltage level. The system is placed in a test mode of operation in response to a uniquely characterized, humanly generated input sound signal and then can be tested by any appropriate humanly generated input sound signal. The system continually monitors ambient background noise and determines when an absence thereof occurs so as to provide an indication of such absence to alert the user to the possibility that the system may have been purposely comprised. The system further uses a number of indicators arranged so that the meanings thereof are different depending on whether the system is in an alarm detection mode of operation or in a test mode of operation.
