  • Patent number: 6771823
    Abstract: A method of coding and transmitting moving pictures includes the steps of coding an extended background image, coding parameters indicative of an image area within the extended background image, coding a foreground picture that is to be composed with a background picture corresponding to the image area indicated by the parameters, coding a defocus value indicative of an extent to which the background picture should blur, and transmitting the coded extended background image, the coded parameters, the coded foreground picture, and the coded defocus value as a data stream to a decoder side. Coding and transmitting of the defocus value makes it possible to defocus the background picture at the decoder end, thereby producing a composed image of the background picture and the foreground picture having natural appearance.

  • Patent number: 6676437
    Abstract: Insulation displacement type contacts (3) each having a receptacle portion (9) are individually held in compartments (4) that are formed in an insulated housing (2). A stationary die (21) temporarily holds an electric connector (1) having such contacts (3). A punch (22) facing and cooperating with this die (21) will reciprocate vertically to press wire ends (15) into the receptacle portions (9) so as to establish electric connection between each wire end (15) and each portion (9). In order to protect these portions (9) from being forcibly widened when an insulation displacement operation is done, a pair of upright guards (31,32) formed integral with a supporting plate (33) are disposed in the die (21). These guards (31,32) are spaced from one another a distance equal to the sideways width of the insulated housing (2), so that its end walls (6,6) are propped up by these guards from the outside.
