    摘要: The loudspeaker has a first pair of drivers arranged in a line, a center point along the line, wherein the pair of drivers are substantially centered about the center point with a center to center distance, d0, between the drivers in the first pair of drivers, whereby the maximum frequency with out high amplitude side lobes is equal to c/2d0, and at least a subsequent pair of drivers arranged in the line array with the first pair of drivers and substantially centered about the center point, wherein the subsequent pair of drivers are spaced such that the center to center distance between each driver in the subsequent pair, dn, is equal to 4nd0, where n=0 at the innermost pair of drivers and n increases by 1 with each pair of drivers sequentially added. Each pair of drivers for n>0 has a first order low pass filter with a frequency equal to 2c/dn.

    摘要: A speaker system utilizes dipole speaker drivers in conjunction with monopole speaker drivers in a listening area to disperse a surround sound effect to a listener. The dipole speaker drivers are physically mounted on top of the front left and right speakers and are angled in a way that the surround information is delivered to the listener via wall/room reflections. By reflecting the sound off the walls, the system provides a delayed diffuse audio signal from the dipole speakers, enhancing the surround effect.

    摘要: Various techniques for controlling the flow of a test sample through an electrochemical-based assay device are provided. The assay device contains a porous membrane provided with certain properties to selectively control the flow of a test sample to a detection working electrode. The detection working electrode communicates with affinity reagents, such as redox mediators and capture ligands. For instance, capture ligands that are specific binding members for the analyte of interest are applied to the detection electrode to serve as the primary location for detection of the analyte.

    摘要: The present invention relates to a mobile boom-mounted shop light, particularly adapted to use in connection with the maintenance and repair of all types of motor vehicles. The present invention provides for four separate degrees of freedom in positioning the light fixture by employing an articulated boom arrangement. The present invention comprises a mobile base, a vertical stand and a boom assembly comprising an arm, a light fixture and a counter weight. The boom assembly allows the light fixture to be rotated transversely about the upright longitudinal axis of the stand, to be rotated vertically, to be rotated about the axis of the boom assembly and to be pivoted from its position on the end of the boom assembly. The position of the light and boom assembly are fixed by a brake and friction plate mechanism.
