  • Patent number: 7639513
    Abstract: An enclosure is formed by folding an FPC board having, on the top face thereof, electronic components and, on the back face thereof, a ground conductor pattern in such a way that the electronic components mounted thereon are housed inside the enclosure. The electronic components housed inside the enclosure are covered with the ground conductor pattern. This means that the enclosure serves as a shield enclosure that electromagnetically shields at least part of the electronic components from the outside. In this way, the shield enclosure is formed by folding the FPC board. This makes it possible to realize an electromagnetic shield structure without using an extra shield case as used in the conventional modules.

  • Publication number: 20090315920
    Abstract: In a display control circuit of this invention, a write gray scale level determining part outputs write gray scale level data for performing overshoot drive on a liquid crystal display device. Moreover, an achievable gray scale level determining part outputs achievable gray scale level data indicating a gray scale level which achieves after a lapse of one frame. Further, an error noise predicting part compares, with a predetermined threshold value, predicted values as differences between gray scale level values of plural pieces of input image data and a mean gray scale level value of these gray scale level values to control a data selecting part such that when at least one of the predicted values exceeds the threshold value, the data selecting part gives, to an image compressing part, the input image data rather than the achievable gray scale level data predicted that a decoding error becomes large. This configuration allows suppression or elimination of after-image noise.

  • Patent number: 7636132
    Abstract: A central wireless microcomputer of a central wireless unit (transmitter) constituting a wireless AV system identifies a content type of video and audio data to be transmitted, according to EPG, and sets a transmission rate of the video and audio data to be transmitted, according to a detected communication condition. According to the content type thus identified, the central wireless microcomputer executes transmission rate modification control by modifying the transmission rate thus set, with reference to an MPEG rate. Thus, even when the communication condition deteriorates, it is possible to minimize deterioration of the video and audio data and maintain data transmission as much as possible.

  • Patent number: 7635852
    Abstract: A device unit 46 is constituted by including a lead frame 50 on which a light-emitting mold portion 48 and a light-receiving mold portion 49 are mounted. Moreover, an exterior casing for housing the device unit 46 is constituted of two parts dividable into an upper casing 45 and a lower casing 47. Thus, by holding the device unit 46 by the upper casing 45 and the lower casing 47, external connection terminals 43 constructed of one end portion of the lead frame 50 can be fixed to the exterior casing and positioned in a connector portion 42. Therefore, by reducing the parts count to three and allowing the device unit 46 to be fixed to the exterior casing by a fixed fitting mechanism of the upper casing 45 and the lower casing 47 without performing welding, soldering, thermal caulking or the like, the assembling becomes easy.
