    摘要： In accordance with the principles of the present invention, advantage is taken by the inventors of the fact that the speed of operation of the digital hardware in a digital beamformer having a plurality of parallel receiving channels can be reduced by providing multiple phases for the data signals supplied by each receiving channel and then processing the multi-phase data in N parallel summing paths. An interpolation-decimation filter receives the multi-phase data from the N parallel summing paths and provides at its output a signal having a reduced data rate (1/N). In accordance with this technique, the speed of operation of the individual digital circuits for forming the required beamforming delays are not increased as compared to conventional post-beamforming interpolation schemes, so that hereby the effective data rate is increased by a factor N and the delay quantization error is reduced by a factor N.

    摘要： In accordance with the principles of the present invention, advantage is taken by the inventors of the fact that the speed of operation of the digital hardware in a digital beamformer can be reduced by providing, for example, multiple phases of the data signals and then processing the multi-phase data in N parallel summing paths. An interpolation-decimation filter receives the multi-phase data from the N parallel summing paths and provides at its output a signal having a reduced data rate (1/N). In accordance with this technique, the speed of operation of the individual digital circuits for forming the required beamforming delays is not increased as compared to conventional post-beamforming interpolation schemes, so that hereby the effective data rate is increased by a factor N and results in a decrease of the delay quantization error by a factor N. In accordance with the principles of the invention, the interpolation-decimation filter is incorporated into the beamformer at a most advantageous place. That is, it is incorporated into the beamformer processing after partial beamforming of a group of receive channels and before formation of the final beam. This approach allows the final beamforming to be simple and performed at a relatively low data rate and allows the higher rate signal processing to be confined to circuitry which may advantageously be on a single type of integrated circuit which is repetitively used in the beamformer.

    摘要： An apparatus and method for removing noise from a signal S(x). The noise is removed by filtering S(x) through a low pass filter having an adjustable pass band. A control processor analyzes S(x) prior to S(x) being input to the low pass filter and adjusts the pass band in response to an estimate of the SNR or rate of change of S(x) such that the pass band is reduced when the estimated SNR decreases and the pass band is increased when the SNR increases. In embodiments in which the control processor utilizes the rate of change of S(x) to control the pass band, the pass band is reduced when the rate of change of S(x) increases and increased when the rate of change of S(x) decreases. In embodiments used in ultrasound applications, the estimate of the SNR can be obtained from x, the power in S(x), or the variance in the measured velocity. The estimate of the rate of change of S(x) may be computed from an estimate of the correlation distance in S(x).

    摘要： A light guide plate and a liquid crystal display device having the same. The light guide plate is disposed upstream of a liquid crystal panel to refract light supplied through an edge thereof, toward the liquid crystal panel. In the light guide plate, a plate body is disposed at a side of a light source for supplying light when a supply voltage is applied. A plurality of pyramidal diffusing elements are arrayed in a predetermined pattern on a surface of the plate body. Each of the diffusing elements is rotated clockwise or counterclockwise about an axis extending through a vertex of the diffusing element perpendicularly to the surface of the plate body so that an edge of the diffusing element facing a reference line connecting a central point of the light source to a central point of the plate body is angled 10° to 35° about the reference line.

    摘要： Conventional rechargeable battery packs for portable electronic products possess charging terminals for connecting the battery packs to charging devices. When a portable electronic product is in use, there is a potential for short circuiting the battery pack by connecting one or more objects to the exposed charging terminals. This invention provides a battery pack for a portable electronic product with a short circuit prevention function where the charging terminal is exposed only when plugged into a charging device. By protecting the charging terminals, the invention prevents a short circuit from occurring during normal operation of the portable electronic product. The battery pack with a short circuit prevention function comprises a spring-loaded cover that is adapted to travel over the main body of the battery pack to alternately cover and expose the charging terminal.
