  • Patent number: 6300872
    Abstract: A security system incorporates a reasoning system and security rules and processes that are designed to be as unobtrusive as the situation permits. Two independent aspects of the system facilitate the enforcement of rules and processes in an unobtrusive manner. First, transponders that can be triggered and sensed from a distance are preferably used to identify both items and individuals. These remotely sensed identifiers are processed by the reasoning system to determine whether each identified item is authorized, or likely to be authorized, to be removed from, or brought into, a secured location by the identified individual. Second, the system continually modifies and optimizes its rules and processes based on assessments of security events. An initial set of rules is created for the security system that, generally, prohibit the removal of secured items from the secured location, except that certain individuals are authorized to remove specified items from the secured location.

  • Patent number: 6295647
    Abstract: In a digital television broadcast that contains executable code segments that are associated with specific video segments, a context duration time is defined for each executable component. The context duration time is determined so as to correspond to the context of the video segment that is associated with the executable component. In a preferred embodiment, the context duration time for the executable component is determined when the corresponding video segment is being prepared for encoding into the transport stream. The context duration time is subsequently included in the encoding of the executable component in the transport stream. When the executable component is decoded from the transport stream, the context duration time is used to effect a termination of the executable component after the context duration time has elapsed.

  • Patent number: 6285892
    Abstract: The system transmits data between terminals of a wireless network. In the system, a base station/central controller (“BS/CC”) controls transmission of data from a transmitting terminal to plural receiving terminals, where the data is ordered in slots of a control data frame (“CDF”), and where each slot is reserved for a data transmission between the transmitting terminal and a specific receiving terminal. Specifically, the BS/CC divides the plural receiving terminals into a set of power-saving terminals and a set of non-power-saving terminals, and then reserves a set of slots in the CDF for data transmission between the transmitting terminal and the power-saving terminals, and another set of slots in the CDF for data transmission between the transmitting terminal and the non-power-saving terminals.

  • Patent number: 6285127
    Abstract: A flat display device, preferably of the PALC type, in which the plasma channels are formed by etching laterally-spaced slots in a spacer plate, attaching a thin dielectric sheet over the etched spacer plate, and bonding the etched spacer plate to a transparent substrate such that each channel is formed by the portion of the substrate between flanking walls formed by the etched slots in the spacer plate, adjacent flanking walls in the spacer plate, and the overlying portion of the thin dielectric sheet. By positioning the flanking walls between channel electrode pairs, thus providing glass-to-glass interfaces, anodic bonding can be employed to assemble the three channel elements. Etching can be simplified by pre-attaching the unetched channel plate to the substrate or thin dielectric cover sheet with an intervening etch stop, and etching in situ using the etch stop to prevent etching of the substrate or thin dielectric cover sheet.

  • Patent number: 6282322
    Abstract: This invention relates to systems and methods for increasing image compression. The systems and methods are improvements applicable to encoder/decoders which compress images by, inter alia, transforming non-overlapping independent blocks of pixels into a frequency domain and then quantizing the resulting frequency domain coefficients. The invention achieves increased compression by predicting low frequency coefficients of a block from, preferably, the average intensities, or zero frequency coefficients, of the block and its adjacent blocks. In an encoder, the low frequency coefficients are predicted, are then subtracted from the actual transform coefficients, and the difference coefficients are transmitted to a decoder. In the decoder, the low frequency coefficients are again predicted, are added to the received difference coefficients, and the resulting actual transform coefficients are used to reconstruct an image.

  • Publication number: 20010015289
    Abstract: An air-wound, coil-type, passive inductor includes a surface which allows the coil to be picked-up using a vacuum probe of a head of a pick-an-place machine and the surface does not interfere with adjusting the spacing between the loops of the coil for tuning the coil after the coil is attached to a circuit board. Terminal ends of the coil are placed on solder paste on interconnection pads on the circuit board, then the board is heated to reflow the solder, and then washed to remove the flux contained in the solder paste. The surface may be adapted to be removed or at least degraded by the heating, or the washing, or afterwards by a mechanical method of removal without damaging the coil.

  • Patent number: 6271944
    Abstract: A method and apparatus for controlling and stabilizing laser wavelengths in a dense wavelength division multiplexer (DWDM) transmission system. The lasers in the transmission system are each modulated in a known manner by a data signal. In addition, the lasers are each modulated by a plurality of test signals each having a predetermined frequency. At the optical receiver, a frequency analyzer examiners the frequency test signals for distortions and/or changes in amplitude. Any distortions and/or changes in amplitude of the frequency test signals indicate a change in the wavelength of a corresponding laser. A control signal may be returned to the laser controller of each laser to regulate the laser wavelength. A fault signal may be generated indicating that the wavelength of a laser has changed, drifted, etc., more an acceptable amount.

  • Patent number: 6263022
    Abstract: There is disclosed an adaptive quantization controller for use in a video encoder comprising a base layer circuit for receiving an input stream of video frames and generating compressed base layer video frames suitable for transmission to a streaming video receiver and an enhancement layer circuit for receiving the input stream of video frames and a decoded version of the compressed base layer video frames and generating enhancement layer video data associated with, and allocated to, corresponding ones of the compressed base layer video frames. The adaptive quantization controller receives at least one quantization parameter from the base layer circuit and, in response thereto, determines a corresponding shifting factor for shifting a bit plane associated with the enhancement layer video data. The adaptive quantizaion controller also modifies a data field in the enhancement layer video data to cause the video streaming receiver to assign a higher decoding priority to the shifted bit plane.

  • Patent number: 6263113
    Abstract: In order to detect a face disposed within a digital image, the pixels of the image are grouped based on whether they are skin color. The edges of the skin colored areas are removed by eliminating pixels that have surrounding pixels with a high variance in the luminance component. The resulting connected components are classified to determine whether they could include a face. The classification includes examining: the area of the bounding box of the component, the aspect ratio, the ratio of detected skin to the area of the bounding box, the orientation of elongated objects, and the distance between the center of the bounding box and the center of mass of the component. Components which are still considered facial candidates are mapped on to a graph. The minimum spanning trees of the graphs are extracted and the corresponding components which remain are again classified for whether they could include a face.
