摘要： An electronic blood pressure meter determines, in an inflation process, pressure Ps correlated to systolic pressure, pressure Pd correlated to diastolic pressure and pulse wave period Pc, and then calculates deflation rate def−v in a deflation process based on a first formula (def−v=(Ps−Pd−mb1)×Pc/N, where N represents the number of required beats). Further, maximum inflation value Inf−max is calculated based on a second formula (Inf−max=def−v·(np×Pc+&agr;)+Ps+&bgr;1). The pressure is increased to reach the calculated maximum value and then deflation is started at the calculated deflation rate . The blood pressure meter can thus perform a precise measurement in a shortest time.

摘要： In a subband echo cancellation for a multichannel teleconference, received signals x1(k), x2(k), . . . , xI(k) of each channel are divided into N subband signals, an echo y(k) picked up by a microphone 16j after propagation over an echo path is divided into N subband signals y0(k), . . . ,yN−1(k), and vectors each composed of a time sequence of subband received signals x1(k), . . . , xI(k) are combined for each corresponding subband. The combined vector and an echo cancellation error signal in the corresponding subband are input into an estimation part 19n, wherein a cross-correlation variation component is extracted. The extracted component is used as an adjustment vector to iteratively adjust the impulse response of an estimated echo path. The combined vector is applied to an estimated echo path 18n formed by the adjusted value to obtain an echo replica. An echo cancellation error signal en(k) is calculated from the echo replica and a subband echo yn(k).

摘要： An apparatus and method for coding and decoding digital video images, capable of maintaining the quality of static regions, such as background images, in decoded pictures even when the resolution of pictures has been changed from high to low. The apparatus is equipped with two storage units, low-resolution and high-resolution picture storage units, to hold reference pictures in two different picture formats. When processing coded blocks (or blocks having at least one non-zero transform coefficient), a high-resolution picture updating unit converts corresponding blocks of a low-resolution reference picture retrieved from the low-resolution picture storage unit to obtain high-resolution block images. It then updates a high-resolution picture stored in the high-resolution picture storage unit with the obtained high-resolution block images. This updating operation is not applied on non-coded blocks. As a result, only active regions corresponding to the coded blocks are updated within the picture stored in the high-resolution picture storage unit, while the remaining part, which may possibly be static background images, is preserved without losing their high visual quality.
摘要翻译：数字视频图像的编码和解码装置和方法，即使当图像的分辨率从高变为低时，也能够在解码图像中保持诸如背景图像之类的静态区域的质量。该设备配备有两个存储单元，低分辨率和高分辨率图像存储单元，以保存两种不同图像格式的参考图像。当处理编码块（或具有至少一个非零变换系数的块）时，高分辨率图像更新单元将从低分辨率图像存储单元检索的低分辨率参考图像的相应块转换为高分辨率块图片。然后利用获得的高分辨率块图像来更新存储在高分辨率图像存储单元中的高分辨率图像。该更新操作不适用于非编码块。结果，只有与编码块相对应的有效区域在存储在高分辨率图像存储单元中的图像内被更新，而可能是静态背景图像的剩余部分被保存而不会失去其高的视觉质量。

摘要： A two-dimensional discrete cosine transform computing circuit has a transform block, formed by a multiplication unit and a Hadamard transform unit, which performs computations in a sequence of Hadamard transforms followed by multiplications in a two-dimensional discrete cosine transform, and in a sequence of multiplication followed by Hadamard transforms in an inverse two-dimensional discrete cosine transform. A memory block temporarily stores input/output data of the transform block; an input/output processing block performs pre-processing and post-processing such as cumulative addition and subtraction of input/output data of the transform block. A control block controls, when performing processing for either a two-dimensional discrete cosine transform or inverse two-dimensional discrete cosine transform, multiplications of coefficients in the transform block, read/write of the memory block, and the input/output processing block. This configuration achieves high-speed processing and a reduction in scale of the circuitry.

摘要： A disk recording device of the invention has a detector for detecting the position of an optical head with respect to the radial direction of a disk, using an optical scale, and a position signal processing circuit for generating a position signal from the output signal from the detector. An output signal from the circuit is converted by a D/A converter into a voltage signal, which is supplied to a voltage controlled oscillator. The oscillator generates a frequency signal. The frequency signal is supplied to a page buffer storing video data and one input of an AND circuit. The other input of the AND circuit is connected to receive a video data from the page buffer. The AND circuit generates a logic product of the frequency signal and the video data, or a recording timing signal having a frequency which is proportional to the position of the head with respect to the radial direction of the disk.
