  • Patent number: 7934945
    Abstract: An embodiment of an electrical connecting apparatus comprises a support board, a plate spring arranged on the support board, an attachment device attaching the plate spring to the support board, a block having an attachment surface directing downward, and a flexible circuit board in which a plurality of contactors are arranged. As for the block, the attachment surface for attaching the circuit board is protruded further to the lower side than the support board. The plate spring receives initial load to bring a state where at least a center area for attaching the block is biased toward the upper side. Thus, a good electrical contacting state can be obtained without increasing the overdriving amount.

  • Patent number: 7924824
    Abstract: A voice packet communications system which objectively evaluates the voice quality in real time. Voice packets received from a network are input into an adjustment circuit. The adjustment circuit evens out the periods of the voice packets, detects the drop-out of voice packets, and inserts substitute packets in the voice packet sequence. Furthermore, the adjustment circuit outputs the number of voice packets that have dropped out, the number of substitute packets that have been inserted, and the number of voice packets that have accumulated inside the circuit, as quality information in each monitoring period. A decoding circuit converts the voice packets adjusted by the adjustment circuit into voice information. A judgement circuit calculates an index that indicates the communications quality of the voice packets from the quality information using a specified calculation formula.

  • Patent number: 7899208
    Abstract: The present invention relates to image processing apparatus and method, a recording medium, and a program for providing reliable tracking of a tracking point. When a right eye 502 of a human face 504 serving as a tracking point is tracked in a frame n?1 and when a tracking point 501 appears as in a frame n, the tracking point 501 continues to be tracked. When, as in a frame n+1, the right eye 502 serving as the tracking point 501 disappears due to the rotation of the face 504 of an object to be tracked, the tracking point is transferred to a left eye 503, which is a different point of the face 504 serving as the object including the right eye 502. The present invention is applicable to a security camera system.
