Abstract: A method and apparatus for ascertaining the depth of anesthesia of the patient. In one embodiment, the entropy of the patient's EEG signal data is determined as an indication of the depth of anesthesia. A frequency domain power spectrum quantity is obtained from the patient's EMG signal data. The latter quantity can be updated more frequently than the EEG entropy due to its higher frequency. The EEG entropy indication and the EMG power spectrum indication can be combined into a composite indicator that provides an immediate indication of changes in the state of the patient. In a further embodiment, the frequency range over which the entropy of the biopotential signal from the patient is determined is selected to encompass both EEG signal data and EMG signal data and the entropy so determined used as an indication of the patients state. In addition, entropy of the EEG range alone can be used together with the entropy of the broadened range to indicate separately contributions from EEG and EMG.

Abstract: A programmable mixer includes a 1st mixing stage, a 2nd mixing stage, a coupling element, and a compensation module. The 1st mixing stage is operably coupled to mix one leg of a differential input signal with a differential local oscillation. The 2nd mixing stage is operably coupled to mix the other leg of the differential input with the differential local oscillation. The coupling element couples the 1st and 2nd mixing stages together. The compensation module is operably coupled to the 1st mixing stage and/or the 2nd mixing stage to modify the operational characteristics (e.g., current, impedance, gain, et cetera) of the 1st and/or 2nd mixing stages based on a control signal.

Abstract: In a semiconductor memory device including a plurality of memory chips, the plurality of memory chips are divided into first and second groups that are operated in parallel with each other at the time of a data read. Timings of activating sense amplifiers belonging to the first and second groups are made different from each other. Accordingly, the maximum value of peak current generated when the sense amplifiers are activated at the time of a data read is reduced by half in the semiconductor memory device as a whole. As the peak current is suppressed, the data reading operation can be executed stably.

Abstract: An optical fiber cable structure including a tube comprised of inorganic fillers dispersed within a soft resin, the tube housing optical fibers or ribbons surrounded by a water blocking material. The use of the inorganic fillers in the soft resin provides a cable structure with superior blowing performance due to low surface friction and high flexibility, allowing more effective installation of the fiber optic cable via blowing techniques The use of the inorganic fillers in the soft resin also reduces the thermal expansion/contraction of the cable structure, and increases the compression resistance of the cable structure to axial loads, providing protection to the optical fibers.

Abstract: An object is to obtain a three-dimensional graphics system capable of color display with reduced operation time. A color data transform portion (2A) extracts the upper k (k<n) bits from n bits for each of R, G and B in RGB original color data (C1) in geometrically-processed three-dimensional data (D1) and transforms the RGB original color data (C1) into reduced color data (C2) in such a manner that the sets of k bits are assigned respectively to R, G and B, thus providing color data for three-dimensional data (D2) to be used in the drawing operation. A drawing operation portion (3A) applies drawing operations including color processing operation based on the reduced color data (C2) to the three-dimensional data for drawing operation (D2) obtained from the color data transform portion (2A) and outputs three-dimensional graphic drawing data to a drawing unit (4). The drawing unit (4) displays three-dimensional graphics in color on a display screen in a display unit.

Abstract: A method and system of TMAH concentration adjustment. Absorption values A1, Y1 to Ym of a recycled developer solution at wavelength 210 nm and m wavelengths between 220 nm and 250 nm are measured respectively, wherein m is equal to or greater than 2. Y1 to Ym are input to an nth-degree polynomial to generate a wavelength-absorption relationship Y=C1Xn+ . . . +Cn−1X+Cn, wherein X is wavelength, n is a positive integer and C1 to Cn are coefficients of the relationship. Wavelength 210 nm is input into the wavelength-absorption relationship to generate an absorption value Y210. A difference A3 between the A1 and Y210 is calculated as the absorption value of TMAH in the developer solution and A3 is then input to an absorption calibration curve of TMAH at 210 nm to generate a corresponding TMAH concentration. TMAH is then added to provide the corresponding TMAH concentration.

Abstract: A computer system having a sensing circuit for detecting a user status and switching a computer accordingly as well as an automatic networking capability. As a user walks into a sensing area, the computer starts up automatically so that some waiting time can be saved. Similarly, when the user walks away from the sensing area, the computer shut down automatically so that some power can be saved. The computer system includes a signal generator that sends out a transmission signal for determining if a user is within a detectable region. A signal receiver emits an appropriate status signal after picking up the transmission signal from the detection region. The status signal is processed by various devices including an analogue/digital converter, a delay unit, a logic circuit and a microprocessor before arriving at a power-triggering mechanism to switch on or off the computer accordingly.
