  • Publication number: 20110235454
    Abstract: A high-voltage selecting circuit generates an output voltage with no voltage drop by means of an auxiliary NMOS transistor turning on the corresponding selecting PMOS transistor of the high-voltage selecting circuit when the voltage levels of a first input voltage and a second input voltage are equal. In addition, when one of the first input voltage and the second input voltage is higher than the other one, the high-voltage selecting circuit avoids the leakage current by means of an auxiliary PMOS transistor turning off the corresponding selecting PMOS transistor of the high-voltage selecting circuit. In this way, the high-voltage selecting circuit can correctly generate the output voltage according to the first input voltage and the second input voltage, and avoid the leakage current at the same time.

  • Patent number: 7958356
    Abstract: A system and method securely establishes a shared secret among nodes of a security appliance. The shared secret is established by distributing private keys among the nodes in accordance with a node ring protocol that uses a predetermined encryption algorithm to generate messages containing the keys. Briefly, each node is initially notified as to the number of nodes participating in the shared secret establishment. Each node generates a public-private key-pair, as well as a first message that includes the generated public key and an indication of the source of the generated public key (hereinafter “source generated public key”). The node then sends the first message to an adjacent node of the appliance. Upon receiving the first message, each node extracts the source generated public key from the message and stores the extracted information into a data structure of “partner” public keys.

  • Publication number: 20110038535
    Abstract: A foreground image separation method is disclosed to separate dynamic foreground and static background in a sequence of input images which have been processed either with automatic white balance or brightness control by the camera. First, an input image is received from the camera, and then a white balance or brightness compensation is performed to the input image according to a reference image to generate a compensated image with background color and background brightness which are approximately similar to that of the reference image. Finally, a background subtraction algorithm is performed to the compensated image to generate a background separation result. The background subtraction algorithm could be a Gaussian Mixture Model based algorithm. The method could process successive images received from the camera to continuously generate background separation results and update the reference image accordingly, such that video surveillance system could adapt to the change of illumination.
