Abstract: A portable radio communication device comprising a housing and a buzzer that rings on activation to alert a user of an event, the buzzer being disposed adjacent the inner surface of the housing and next to an audio outlet orifice for the buzzer provided in the body cover member, wherein the housing has a channelled recess provided in its outer surface in the area of the audio outlet orifice.

Abstract: A method (400) and a system (100) for providing video signals to video displays includes the steps of receiving at least one input video signal (150), dithering the non-uniformity color correction (445), applying the non-uniformity color correction to the input video signal to generate a color corrected video signal (450), and increasing a frame rate of the color corrected video signal (120). Gamma correction (125) can be applied to the color correction. Generating a dithered non-uniformity color correction can include selecting from a data storage (115) a plurality of RGB correction matrices (300), measuring at least one brightness level of the input video signal, selecting for the picture level correction a first RGB correction matrix if the brightness is within a first range of values (425), a second RGB correction matrix if the brightness is within a second range of values (435), and interpolating (440) the plurality of RGB correction matrices if the brightness is within a third range of values.

Abstract: A digital video system includes a sample rate converter and an inverse-sample rate converter. The sample rate converter converts video data from a non-orthogonal pixel domain to an orthogonal pixel domain. The inverse-sample rate converter converts the video data from the orthogonal pixel domain to the non-orthogonal pixel domain. The inverse sample rate converter utilizes a timing signal generated by the sample rate converter when converting the video data from the orthogonal pixel domain to the non-orthogonal pixel domain.

Abstract: Portable apparatus comprising a display 4 having an electrical interface 5 with at least one electrical contact 24; a circuit board 2 having an electrical interface with at least one electrical contact 12 for supplying current to the display 4; and a frame 7 for securing the display 4 to the portable apparatus and urging the display contact 24 and circuit board contact 12 together to allow current to flow from the circuit board contact 12 to the display contact 24.

Abstract: A keypad assembly is disclosed, which includes a keymat, a switch assembly, and an intermediate element positioned between the keymat and the switch assembly. The intermediate element is configured to provide an aperture associated with a key of the keymat, and a resilient member is attached to the intermediate element, and extends into the aperture. Pressure on a key of the keymat is transferred via the resilient member to a key dome of the switch assembly.

Abstract: An automatic choke assembly or starting aid is coupled with a small internal combustion engine. The choke assembly is responsive to a pressure differential in the internal combustion engine which causes movement of a mechanism to control the amount of combustion air entering into the internal combustion engine. The mechanism provides sufficient combustion air during start-up and during continuous running condition of the internal combustion engine.

Abstract: A vapor return primer for priming and regulating pressure in a carburetor is disclosed. The vapor return primer includes a housing having an inlet and an outlet. The inlet is coupled with the high pressure side of the carburetor. The outlet is coupled with a fuel tank. A resilient flexible membrane is coupled with the housing for moving fluid through the inlet and outlet to prime the carburetor. A pressure relief mechanism is coupled with the housing to provide one-way flow from the housing through the outlet to the fuel tank during priming. Also, the pressure refief mechanism regulates the carburetor pressure when the internal combustion engine is in a continuous running mode.
