  • Patent number: 10775008
    Abstract: The invention proposes a lighting device, in particular an emergency lighting device. The lighting device includes a first housing (2), a lighting means (12), for example an LED arranged at the first housing (2) and an electronic circuitry accommodated in the first housing (2) for operating the lighting means (12). A second housing (3) of the lighting device accommodates an energy storage means (13) such as a rechargeable battery, wherein the first housing (2) and the second housing (3) are arranged spaced apart. An interconnecting means (4) mechanically connects the first housing (2) and the second housing (3) in an elastic manner and also connects electrically the electronic circuitry and the energy storage means (13). The interconnecting means (4) of the lighting device of a preferred embodiment comprises a cable which is overmoulded to provide compressive strength in an axial direction of the cable.

  • Patent number: 5982439
    Abstract: A system encodes video frames in accordance with the MPEG standard, in real-time. Motion vectors are calculated during the forward prediction of B frames and P frames using a telescoping procedure. Similarly, a telescoping procedure is used for calculating motion vectors for B frames during backwards predictive coding. The use of telescoping for the backward predictive coding results in B frames being coded in the wrong order. The correct order for B frames is re-established by writing the frames to a buffer in the order in which they are generated and then reading the frame data from the buffer in the order in which they are required for transmission or recording purposes. The use of the telescoping procedure reduces significantly the amounts of computation required for calculating motion vectors during predictive coding for frames which are displaced by more than one frame period.

  • Patent number: 5748248
    Abstract: Telescopic predictive coding of video frames reduces the number of pixels in a reference frame which are required to be processed. However, given that offsets for adjacent blocks may differ, it is difficult to parallel process for real-time coding. After first-frame motion vectors have been calculated, a region of the reference pixels is read which is large enough to accommodate the direct calculation of motion vectors for the second frame, thus allowing pixel values to be processed in parallel. However, although all of the read pixels are made available to each processor, the processors only latch the values which are actually required for the particular motion vector being calculated. This is achieved by supplying an enabling signal to the processors, which is determined by processing the first-frame motion vectors.

  • Patent number: 5349383
    Abstract: A method of coding a video signal for transmission includes the steps of coding data representing the video signal by a base layer coding operation which includes base layer quantizer having a base layer quantization step size to provide coded video data for transmission; deriving inverse-coded video data by carrying out an inverse base layer coding operation on the coded video data; deriving difference data from the data representing the video signal and the inverse coded video data; and coding the difference data by an enhancement layer coding operation only when the energy of the difference data exceeds a variable threshold, the threshold being inversely proportional to the base layer quantization step size.

  • Patent number: 5206723
    Abstract: A motion vector for motion-compensated prediction in an inter-frame differential video coder is derived by comparing each block in a row of a current frame with the corresponding region, and positionally shifted regions, of a previous frame. The blocks are processed row by row, and scanned in a vertical column-by-column scan with each of the shifted regions. Two or more rows may be processed at a time. For .+-.7 pixel search, two or four comparison processors are provided, one (or one pair) processing odd-numbered blocks and the other (or other pair) processing even-numbered blocks. For a .+-.15 pixel search, four or eight processors are provided. The vertical scan is provided using a serial FIFO store including eight 8 tap SIPO sections.

  • Patent number: 5083202
    Abstract: A motion vector suitable for motion-compensated prediction in an inter-frame differential video coder is derived by comparison of each block of a current frame and with shifted corresponding region of a previous frame with the regions of the previous frame. Rather than dealing with each block in turn, the apparatus carries out all comparisons involving a line n of the video signal before commencing comparisons involving n+p (where p is the number of lines encompassed by a block).
