  • Publication number: 20020070858
    Abstract: A security system including: a camera mounted to a door for capturing image data of an individual approaching the door; and a processor for further processing the image data. Preferably, the system includes: a database for storing the image data; and a recognition system for analyzing the stored image data. The stored image data in the database are preferably face images and the recognition system is preferably a face recognition system. The database can contain image data for each authorized individual of the structure where the recognition system compares images of the individual from the camera with the stored image data to determine if the individual is one of the authorized individuals. The system includes a sensor, operatively connected to the door knob of the door, for detecting the arrival of the individual approaching the door and signaling the camera to capture the image data of the individual upon operation of the door knob.

  • Publication number: 20020071230
    Abstract: The invention provides a way of protecting a differential pair of bipolar transistors by diverting the current into an n-channel MOSFET which is driven into conduction during an ESD event and allows a larger swing of input voltage than the anti-parallel diode pair. No extra processing steps are required and the MOSFET is driven on, rather than relying on parasitic bipolar npn transistor triggering into snap-back as in the grounded gate NMOS transistor that is commonly used for ESD protection in CMOS integrated circuits. According to the present invention, an ESD protection circuit is provided for protecting a differential pair of transistors having two input terminals.

  • Publication number: 20020067209
    Abstract: A power amplifier circuit includes an amplifying transistor and a dc bias circuit for biasing the amplifier transistor to obtain a conduction angle of at least about 180°. The dc bias circuit includes a self-bias boosting circuit for initially decreasing and then increasing the dc bias voltage provided to a control terminal of the amplifying transistor by the dc bias circuit as the input signal provided to the power amplifier increases. The self-bias boosting circuit is extremely simple and compact in design, and permits the power amplifier circuits to operate in Class B or Class AB with improved power output characteristics.

  • Publication number: 20020067780
    Abstract: In a method of demodulating and decoding an encoded interleaved signal, a received encoded interleaved signal is demodulated, thereby producing soft-decision demodulated output words. Thereafter, the soft-decision demodulated output words are de-interleaved and scaled, thereby producing de-interleaved and scaled words. The scaling is performed for a plurality of successively demodulated output words at a time, thereby applying a scale factor that is substantially constant over the entire span of an interleaving frame. The de-interleaved and scaled words are word-length-reduced words. Finally, the de-interleaved and scaled words are decoded.

  • Publication number: 20020067253
    Abstract: An alarm system having an alarm portion and a portable device. The portable device has a form-factor of a key. The key wirelessly receives alarm status information from the alarm portion and displays an alarm status indication in response to the received alarm status information. The key utilizes a processor connected to a memory, a display, and a status inquiry actuator. The memory stores control/display data. The processor queries the memory to retrieve corresponding control/display data in response to the received alarm status information. The processor utilizes the retrieved control/display data to produce the alarm status indication. The status inquiry actuator enables a user to make an alarm status inquiry. The processor displays the alarm status indication in response to the alarm status inquiry. The portable device utilizes a transmitter to transmit the alarm status inquiry to the alarm portion.

  • Publication number: 20020068445
    Abstract: A method for depositing an adhesion layer in a contact region on a semiconductor substrate provides for sufficient coverage on the bottom and sidewalls of the contact region. In an example embodiment, a contact region having a bottom and sidewalls has a first coat of the adhesion layer deposited thereon at a thickness greater than the thickness on the sidewall. To compensate for the narrower adhesion layer thickness on the sidewalls, a second coat of the adhesion layer is deposited so that the second coat on the sidewalls is at a thickness greater than the second coat thickness on the bottom. The adhesion layer is titanium nitride although other materials may be used as well.

  • Patent number: 6400100
    Abstract: In a power source system, a method for providing color mixing in a high intensity discharge (HID) lamp comprises the steps of providing a swept frequency signal having a sweeping frequency ranging between a first lower frequency value and a second higher frequency value, within a specified period. An amplitude modulation signal is also provided having an adjustable frequency value and an adjustable modulation index. As a result the sweeping frequency signal is modulated by said amplitude modulation signal. The frequency of the amplitude modulation signal is adjusted until a maximum lamp voltage is detected. Thereafter, the system operates with a modulating frequency that yields the maximum lamp voltage so as to substantially eliminate color segregation in the lamp.

  • Publication number: 20020064227
    Abstract: A method and system for producing decoding the transmission of high-resolution images transmitted as a low resolution spatially scalable FGS encoded base layer and at least one enhancement layer is presented. The low resolution received base layer is representative of a downscaled image of the original image. In this manner, a minimum resolution base layer is transmitted and higher resolutions may be obtained and utilized depending on the available bandwidth and the receiving system resolution capability. In one aspect of the invention, the base layer is decoded and a quality enhancement is next applied to the base layer. The combined base layer and quality layer video frames are then upscaled and the upscaled image is combined with a decoded spatial enhancement layer information. The spatial enhancement layer information fills in resolution lacking in the upscaled base layer/quality layer image. Thus, a high resolution image is formed.

  • Patent number: 6393572
    Abstract: In a master-slave configuration wherein a sleepmode activation is effected by the cessation of a clocking signal, the need for an analog device or auxiliary clock for detecting the cessation of the clocking signal is obviated by anticipating the cessation of the clock signal. Upon anticipating the cessation of the clock signal, the remaining clock signaling before cessation is used as required to effect a controlled power-down of the slave device. By eliminating the need for an analog clock cessation detector, the process tolerance constraints associated with analog circuitry can be avoided, the reliability and robustness of the design is improved, and the required testing is simplified, thereby reducing the cost of the device. In like manner, the elimination of an auxiliary clock generator reduces the cost and complexity of the device and system, and improves the device and system's overall reliability and testability.
