  • Publication number: 20100289961
    Abstract: An image processing circuit and an image processing method thereof are disclosed. A difference value adaptor of the image processing circuit produces a weighing value and a flag value corresponding to the pixel according to the pixel difference value of each pixel of an input video signal. The image processing circuit judges which area among a first area, a second area and a third area the pixel difference value of each pixel falls in according to the flag value. The image processing circuit performs a low-pass filtering processing on the pixel having the pixel difference value falling in the first area, performs a high-pass filtering processing on the pixel having the pixel difference value falling in the second area and performs a luminance transient improvement processing (LTI processing) on the pixel having the pixel difference value falling in the third area.

  • Publication number: 20100277642
    Abstract: A text protection device for de-interlacing operation includes a pixel value difference calculation unit, a text detection unit and a vertical interpolation unit. The pixel value difference calculation unit is utilized for calculating pixel value differences of a plurality of pixels of a field according to a position of a target pixel being inserted into the field. The plurality of pixels forms a detection area corresponding to the target pixel. The text detection unit is utilized for determining whether the detection area includes a text stroke and determining whether the target pixel is located within a range of the text stroke to generate a text detection signal. The vertical interpolation unit performs a vertical interpolation operation to generate a pixel value of the target pixel according to the text detection signal.

  • Publication number: 20100150048
    Abstract: A multicast communication method for relaying a multicast packet from a first member node to a plurality of second member nodes in a wireless network is provided, wherein the first member node and the second member nodes belong to a same group and can communicate with each other via a plurality of non-member nodes. In the multicast communication method, a number and distances of the second member nodes are recorded. The multicast packet is received from the first member node, and a waiting time is determined according to the number and the distances of the second member nodes. Whether the multicast packet is broadcasted by any other relay node is monitored during the waiting time. If the multicast packet is already broadcasted to all the second member nodes by other relay node, the multicast packet is not broadcasted; otherwise, the multicast packet is broadcasted after the waiting time elapses.

  • Publication number: 20100141423
    Abstract: A wireless sensor network and data sensing method thereof are provided. A prediction model is established according to sensed data. When statistical value of the sensed data is within a user allowable range, the average value of the sensed data is returned to a user based on the prediction model. Alternatively, when the statistical value of the sensed data is beyond the user allowable range, actually sensed data is returned to the user based on the prediction model. In addition, the prediction model may further be dynamically updated according to subsequently received sensed data.

  • Publication number: 20100122091
    Abstract: Disclosed relates to an access control system and method based on hierarchical keys. The system comprises an access control server (ACS), a home gateway, and a plurality of sensor devices disposed on a home network. The ACS sets up user's access limits of authority and authorization verifier, and saves the related data of user's password and the user's access limits of authority. The gateway records the authority limits' level and the authority limits' key which are constructed based on a hierarchical key structure. When a user logs in the ACS to request access, an one-time communication key between the user and the home gateway is established by exchanging the ticket and the token that are issued by the ACS. This allows the user to access the information of the sensor devices.

  • Publication number: 20100118909
    Abstract: The present invention provides a miniature high-power laser diode device, which includes a base, a laser chip, an optical fiber guider, and an optical fiber. The base has a groove and a disposing area, and the groove connects to the disposing area. The laser chip is disposed on the disposing area, and the optical fiber guider is disposed at the groove. The optical fiber is disposed in and through the optical fiber guider. The optical fiber has a first end connected to the laser chip. As a result of the cooperation between the optical fiber guider and the groove, the orientation of the optical fiber is simple and precise. The conventional thermal deformation and residual welding stress can be reduced, and the soldering flux applied in a conventional soldering and packaging process of the optical fiber can be omitted, so that the coupling efficiency, the yield, the stability of high power laser output, and the lifetime of the laser diode device of the present invention can be improved.

  • Patent number: 7715106
    Abstract: A liquid-control optical element is provided herein. The optical element includes two liquids with different phases. The two liquids are immiscible and have different optical index. By applying a voltage through electrodes to form an electric field, the slope of an interface between the two liquids is changed. The purpose of changing the slope is to change the shape of the interface or the moving or rotating direction. Thus, according to the law of total internal reflection or the law of refraction, the liquid-control optical element can be used as a liquid shutter device, or a liquid scanner device if a scanning is performed after penetrating the element.
