Abstract: An exemplary liquid crystal display (2) has a liquid crystal panel (50) and a backlight module (20) being disposed under the liquid crystal panel, the backlight module has a light guide plate (21), and a light source having at least one point light source (23), at least one light guide bar (22) transmitting light beams from the at least one point light source, and a reflector (24) reflecting light beams from the at least one light guide bar into the light guide plate.

Abstract: An exemplary light guide plate (2) includes a light output surface (21) on one side of the light guide plate; a bottom surface (22) on an opposite side of the light guide plate; and a plurality of V-shaped refraction interfaces (24) disposed between the light output surface and the bottom surface. The V-shaped refraction interfaces are formed in the light guide plate, which prevents the V-shaped refraction interfaces being pressed by other optical elements. That is, the V-shaped refraction interfaces are secure during assembly and transportation of a backlight module employing the light guide plate. Moreover, the V-shaped refraction interfaces do not occupy a large amount of space, which means that the backlight module can be made thinner.

Abstract: Power selection circuitry that may be employed in redundant power supplies. The power selection circuitry includes a comparator, a symmetric resistor array coupled between the comparator inputs and multiple input voltage sources, a plurality of first switching elements, and control logic/drive circuitry coupled between the comparator output and the first switching elements. The first switching elements connect a selected input voltage source to a load. The comparator compares the voltage levels of the respective voltage sources, and provides a voltage indicating which one of the voltage sources is operational to the control logic/drive circuitry, which applies control signals to the first switching elements to connect the operational voltage source to the load. The symmetric resistor array and a plurality of second switching elements assure that symmetric trip voltages with hysteresis are provided to the comparator.

Abstract: A micromachined hot-wire anemometer having fast response times and higher sensitivities than conventional hot-wire anemometers is provided by micromachining doped polysilicon wires carried on silicon supports cantilevered from a substrate including one or more insulating layers disposed between said substrate and supports. The micromachined polysilicon hot-wire anemometer is fabricated using surface micromachining techniques.A shear stress sensor is micromachined to define a thin diaphragm over a cavity defined in a substrate underlying the diaphragm. The cavity is evacuated, sealed, and a thermistor disposed over the diaphragm. The thermistor is thus thermally insulated from the substrate and provides a low profile shear stress sensor for measuring flow rates in boundary layers above a flow surface.
