摘要： Filter coefficients of matched filters are set equivalent to those of a circuit for multiplying spread spectrum code signals of different frequencies, and a correlation value between each of the spread spectrum code signals and spread spectrum signal data. Such correlation values are averaged by their corresponding square circuits and adders. In a maximum-value selection circuit, the averaged correlation values are monitored for a plurality of samples, thus obtaining both an amount of correction of frequency deviation of carrier wave from the frequency of a pass having the largest one of the correlation values (the most matching frequency) and an amount of phase correction of the spread spectrum signal from positional information (phase information) of a sample of the pass having the largest correlation value.

摘要： For the purpose of detecting a geometric distortion of an image on a screen of a CRT display device, i.e., the deviation of the positional coordinates at a high speed and with a high accuracy, the positions of window images having about 10 rows and 10 columns which are arranged in a matrix on the screen of the display device, including a screen frame, are photographed through a predetermined low-pass filter by a monochromatic CCD camera, and further, both the low-light field picture and the high-light field picture are photographed, whereby the positions of the window images can be detected with a high accuracy within 0.1 CCD pixel by the elimination of a dark current, the normalization of detection sensitivity and the interpolation calculation. Therefore, the detection of the geometric distortion can be performed at a high speed and with a high accuracy by an inexpensive monochromatic CCD camera which has the number of pixels less than the total number of pixels of the display device.

摘要： A magnetic resonance measuring equipment capable of detecting a nuclear magnetic resonance signal with a higher sensitivity and a higher resolution in comparison with related magnetic resonance measuring equipment. The magnetic resonance measuring equipment modulates a nuclear magnetic resonance signal by applying a vibration (sonic wave) of a known frequency, which is higher than the frequency of the nuclear magnetic resonance signal, to an examination object, and detects the modulated signal by performing lock-in detection, which makes it possible that the magnetic resonance measuring equipment detects the nuclear magnetic resonance signal with a high sensitivity. In addition, after irradiating a local area of the object with an ultrasonic wave, and modulating the nuclear magnetic resonance signal derived from the irradiated local area, the magnetic resonance measuring equipment can detect the nuclear magnetic resonance signal with a high resolution.

摘要： A weight value used for a beamforming process performed on received signals in an ultrasound imaging apparatus is obtained with a small amount of computations and with a high degree of precision, even when a method of adaptive signal processing is employed.Multiple elements 401 receive ultrasound signals from a test subject, and the similarity operator 404 obtains the similarity between the received signals x(n). By using the similarity C(n) between the received signals obtained by the similarity operator 404, the adaptive weight operator 407 computes the adaptive weight w(n) in association with the similarity. The beamforming operator 408 uses the adaptive weight w(n) and the received signal x(n) to generate a beamforming output. The imaging processor 108 uses the beamforming output to generate image data. By way of example, the similarity operator 404 performs computations of the similarity in the time direction.

摘要： It possible to provide an ultrasonogram having a preferable spatial resolution and signal/noise ratio. A signal dynamic range is measured so that selection between a linear interpolation or sinc function interpolation is adaptively performed for the signal or weighted averaging of the both is performed. It is possible to set in advance a depth position for switching between the linear interpolation and the sinc function interpolation in a storage unit (21) so that the two interpolation methods are switched from one to the other at the boundary of the depth position.
