  • Patent number: 8638317
    Abstract: Disclosed herein is a display apparatus including: a display panel having a display function and a light-receiving/imaging function; a first image processing section configured to generate a detection signal that indicates whether a to-be-detected object has been detected based on a result of first image processing performed on an image taken by the light-receiving/imaging function; a second image processing section configured to perform second image processing on the image processed by the first image processing section, the second image processing having a heavier processing load than the first image processing; and a control section configured to control an operation of the second image processing section in accordance with the detection signal generated by the first image processing section, and, when it is determined that the processing by the second image processing section is not necessary, control the second image processing section to enter a sleep state.

  • Patent number: 8319749
    Abstract: An image pickup apparatus capable of easily improving the detection accuracy of a touching or proximity object is provided. An offset noise (a reset image R) is obtained by an image pickup process in a state (a reset state) in which an image pickup device is initialized. Moreover, a fingertip extraction process is performed in consideration of the offset noise on the basis of a picked-up image (a shadow image A or a display light-using image B) which is obtained by picking up an image of a proximity object to obtain object information about the proximity object. While an offset noise in the apparatus is easily reduced, object information about the proximity object can be obtained.

  • Patent number: 4366196
    Abstract: A plastic molding strip for automotive vehicles including a core member formed of a hard resin plastic material and a molding member formed of a relatively soft plastic material adhered to the core member. Preferably the core member has a C-shaped cross section and is formed of hard vinyl chloride, and the molding member is formed of soft vinyl chloride bonded at least to the outer surface of the C-shaped core member. The material of the core member may include glass fibers as a reinforcement.

  • Patent number: 4349994
    Abstract: A weather strip assembly for a vehicle window including a weather strip or moulding and a holder. The weather strip is inserted into a gap between a window glass to which the holder is attached and the body of the vehicle. The weather strip has a hat-shaped head portion to partly cover the window glass and the body of the vehicle and a leg portion adapted to be urged against the vehicle body and to be embedded in a bonding agent. The holder has a resiliently reformable elongation which functions to force the leg portion toward the body. The weather strip assembly further may include a member for determining a proper position of the weather strip with respect to the window glass and the vehicle body.

  • Patent number: 3953282
    Abstract: A polyolefin micro-flake aggregation which is easily micro-flakable from the aggregation into a plurality of irregularly shaped micro-flakes suitable for producing synthetic paper, is manufactured from a solution of 5 - 40% by weight of polyolefin such as polyethylene and polypropylene in a solvent such as hydrocarbons and chlorinated hydrocarbons in the presence of a surface active compound of at least 0.01% based on the weight of the polyolefin by spraying the solution which is at a temperature of at least 100.degree.C from a closed container into atmosphere through an orifice.A polyolefin synthetic paper is formed from a suspension of the micro-flakes in an organic liquid such as hydrocarbons and chlorinated hydrocarbons which can swell or partially dissolve the polyolefin.
