  • Patent number: 8080897
    Abstract: Optimal feedback sensing locations are determined based on minimizing the sum of the differences between actual voltages and nominal voltages at the devices being supplied by the voltage regulator. An optimal sense location may be determined to be a location (for example, on a PCB or PKG) where the sensed voltage is equal to the nominal voltage of the multiple devices when the voltage output of the power source(s) is equal to a level that minimizes the sum of the differences between the actual voltages and nominal voltages at the devices being supplied by the power source(s). An optimal sense location may also be determined to be a location where the sensed voltage is equal to the average of the voltages at the devices that are supplied by the power source(s). Visual data is generated, the visual data indicating an area or areas that comprise optimal sense locations and locations that are optimal within a preset tolerance range.

  • Publication number: 20110103641
    Abstract: A video recognition system detects the presence of fire based on video data provided by one or more video detectors, but suppresses the triggering of an alarm in situations based on the selection of acceptable regions and application of rules associated with each acceptable region. A user defines acceptable regions within the field of view of the video detector and associates with each acceptable region a rule. During processing of video data associated with the field of view, video metrics are calculated and analyzed to detect the presence of fire (e.g., flame or smoke). Prior to triggering an alarm, regions identified as indicative of fire are compared with the user-defined acceptable regions. If there is overlap between the two regions, the rule associated with the acceptable region is applied to determine whether the alarm should be suppressed or triggered.

  • Publication number: 20110064264
    Abstract: A video recognition system detects the presence of fire based on video data provided by one or more video detectors. The video recognition system divides each individual frame of video data into a plurality of frame elements and calculates with respect to each frame element a structural feature that the algorithm uses to identify a core region of potential fire. The video recognition system defines a region surrounding the core region and calculates with respect to each frame element within the surrounding region a temporal feature. Based on the calculated temporal feature, the video recognition system associates a representative temporal value with the core region. Based on the structural and temporal features associated with the core region, video recognition system determines whether the video data indicates the presence of fire.

  • Publication number: 20110058706
    Abstract: A video recognition system detects the presence of fire based on video data provided by one or more video detectors. The video recognition system is operable to calculate a first flicker feature with respect to a first set of frame data and a second flicker feature with respect to a second set of frame data. The video recognition system combines the first flicker feature and the second flicker feature to generate an accumulated flicker feature. The video recognition system defines, based on the accumulated flicker feature, a flicker mask that represents a dynamic region of the fire. Based on the defined flicker mask, the video recognition system determines whether the video data indicates the presence of fire.

  • Patent number: 7896253
    Abstract: A method for automatically rectifying business card presentation angle is described. The method is applicable to a mobile electronic device to automatically rectify a presentation angle of a shot business card image. Firstly, maintain character pixels of the shot business card image, and divide the character pixels into character groups by determining whether the pixel pitch is larger than a predetermined value. Next, obtain a first axis and a second axis of the character groups. After that, calculate an included angle formed between the first axis and the second axis, and adjust the oblique character groups through angles obtained for correction. Then, adjust aspect ratios of all the character groups after angle correction according to appropriate character aspect ratios, to make the displayed font seem normal. Finally, generate a corrected business card image according to the character groups after correction.

  • Publication number: 20110033087
    Abstract: A video content analysis (VCA) system generates an output regarding a detected condition that provides an indication of a confidence level regarding the detected condition. One example VCA system determines whether a first characteristic of a detected object in a field of vision of the video content analysis system satisfies a first criterion. If so, a first signal is generated under selected conditions. The VCA system also determines whether a second characteristic of the detected object satisfies a corresponding second criterion. If so, a second, different signal is generated if the first and second criteria are satisfied. The first and second signals indicate respective, different confidence levels that an event has occurred. A disclosed example includes a VCA as part of a security system.
