  • Patent number: 6592528
    Abstract: A biological information evaluation apparatus includes a waveform parameter detection section, a corresponding relation storage section, and a blood vessel evaluation information deriving section. The waveform parameter detection section detects a waveform parameter such as an after-ejection pressure ratio or dicrotic wave height ratio based on a pulse waveform. The corresponding relation storage section stores the corresponding relation between the blood vessel evaluation information and the waveform parameter which is derived in advance. The blood vessel evaluation information deriving section derives the blood vessel evaluation information based on the waveform parameter detected by the waveform parameter detection section and the corresponding relation. The waveform parameter detection section includes a pulse wave sensor which detects the pulse waveform, and a waveform parameter calculation section which calculates the waveform parameter from the pulse waveform.

  • Patent number: 6584043
    Abstract: With respect to a generator (20), a storage device (22) for storing electrical energy output from the generator and a bypass circuit (31) are connected in parallel with each other. A bypass circuit switch (33) of this bypass circuit (31) is controlled on and off according to the voltage of the storage device (22). This makes it possible to reduce the input current into the storage device so as to implement a reduction in the voltage of the storage device, thereby preventing overcharging. Moreover, since a generated waveform corresponding to the rotation period of the generator can be obtained, the rotation period of the generator can be controlled highly precisely and reliably based on this generated waveform, thereby implementing the indication of the correct time.

  • Patent number: 6575618
    Abstract: An information processing device to which data can be input by the use of a rotary bezel. A pulse-count detection sensor unit 32 and a rotational-direction detection sensor unit 33 read an optical pattern which is formed on the rotary bezel to generate a series of pulse signals. The pulse-count detection sensor unit 32 and the rotational-direction detection sensor unit 33 are arranged such that a phase difference occurs between the signals of the sensor unit 32 and the signals of the sensor unit 33, so that it is possible to detect the rotational direction of the rotary bezel. A data-signal generating element 81 generates a data signal on the basis of the detected rotational angle and the pulse count generated by the pulse-count detection sensor unit 32.

  • Patent number: 6573901
    Abstract: A video display controller incorporates an improved half-frame buffer that can be implemented and operated at lower cost. In one implementation, the half-frame buffer incorporates a distribution circuit that receives three serial digital signals conveying bits representing red, green and blue (RGB) colors in an image. The distribution circuit multiplexes the RGB bits into a signal parallel register so that a complete set of RGB information can be written to or retrieved from memory during a single clock cycle. Preferably, the distribution circuit is implemented by simple signal-switching logic.

  • Patent number: 6563766
    Abstract: A voltage detection and a remaining battery voltage display for a secondary power source so as to notify the user of the remaining battery voltage of the secondary power source at the optimal timing and in an accurate manner. A voltage correlated to the power source capacity of the secondary power source is detected as a detection voltage. The detection voltage is directly output if a rapid charging is not being detected. If the rapid charging is being detected, the detection voltage is output after being corrected for an amount of the apparent voltage boost which occurs in the secondary power source due to the rapid charging. The detection voltage thus obtained is compared with a predetermined reference voltage so as to discriminate the remaining capacity of the secondary power source.

  • Patent number: 6557020
    Abstract: An information processing system that is configured in such a manner that computational processing is performed on input data in accordance with a processing sequence, for outputting data, comprises: a plurality of arithmetic units (7-1 to 7-x), each computing at an arithmetic precision 2m bits (where m is a natural number) based on the processing sequence; and a plurality of cascade connection terminals for cascading these arithmetic units each other. When the maximum arithmetic precision that is required during computational processing is 2n bits (where n is a natural number and is fixed), x numbers of (where x is a natural number) the arithmetic units are cascaded in a manner such that the inequality x≧2n/2m is satisfied. When an arithmetic precision of 2n1 bits (where n1≦n, and n1 is variable) is necessary during computational processing, x1 numbers of the arithmetic units are cascaded in a manner such that the inequality x1≧2n1/2m (where x1 is a natural number and is variable) is satisfied.

  • Patent number: 6546132
    Abstract: We improve text reproduction of a scanned and printed image by identifying text-contribution colors and also image-contribution colors that are in or near the text region of the color space. When input colors are encountered that contribute both to text and image we splice together text and image color transformations of the input color to produce a color in the printer color space. We improve background reproduction, i.e. reduce bleed-through artifacts, by identifying background-contribution colors and also image-contribution colors that are in or near the background region of the color space. When input colors are encountered that contribute both to background and image we splice together background and image color transformations of the input color to produce a color in the printer color space.

  • Patent number: 6541882
    Abstract: Inner notches (225A, 226A) for adjusting the cogging torque of a rotor (21) are formed on a stator (22) in a small-size power generator (20). Since the inner notches (225A, 226A) are formed on an inner periphery of a rotor accommodation hole (230) within an angular range of ±45° around a magnetic flux direction of a first magnetic circuit (100) having a smaller magnetic reluctance at a rotation center of the rotor (21), the cogging torque can be effectively reduced. Accordingly, even when the size of components such as an oscillating weight and a power spring is reduced for making a thin timepiece, rotation startability of the rotor can be improved, thus improving power generation efficiency of the small-size power generator.

  • Patent number: 6515864
    Abstract: An add-on cartridge structure for electronic devices having a housing formed from upper and lower case sections. The upper case is typically made from plastic and has a conductive layer formed on inside surfaces, while the lower case is made from a metallic material such as aluminum. A wall-like mating member is disposed on an outer edge of the lower case, and mates with the sides of the upper case to form a nearly rectangular cross section housing. The double conductive layer formed by the outside surface of the mating member and the inside surface of the upper case prevents leakage of electromagnetic radiation from the cartridge. Furthermore, high frequency noise is prevented by grounding both the signal ground of the printed circuit board and the frame ground at multiple locations. The conductive layer has a surface break caused by a through-hole through which the printed circuit board plug protrudes to the outside.

  • Patent number: RE38108
    Abstract: A computer system includes an operator input device, a central processing unit (CPU), and a display device, such as a liquid crystal display (LCD) or cathode ray tube (CRT) providing a visible image to the computer user as an output of computer activity. The computer system includes a video display controller (VDC) with a graphics generator. This VDC receives image information, such as text or graphics generated by the CPU, or retrieved by the CPU from another facility (such as a CD-ROM) of the computer system, and responsively provides image signals driving the CRT or LCD display. The VDC includes a power saving controller implementing one of several available power saving modes dependent upon one or more of several possible inputs. Each of the power saving modes includes the same list of VDC functions which may individually be enabled or disabled in each power saving mode dependent upon a bit value entered into a register of the power saving controller.
