  • Patent number: 10003321
    Abstract: A resistor string outputs sixteen signals with a phase difference of 22.5° by dividing voltage between two adjacent phases of a four-phase input signal with a phase difference of 2?/M (where M is an integer equal to or greater than 2), and by generating four signals with a delayed phase for each phase of the four-phase input signal. A switch portion selects four signals with a phase difference of 90° from the sixteen signals. Amplifiers output each of the four signals, which are attenuated by dividing the voltage with the resistor string, as a four-phase output signal by amplifying each of the four signals such that an amplitude of the four signals matches the amplitude of the four-phase input signal.

  • Publication number: 20110147569
    Abstract: An optical control system is described, which employs a series of optical emitters and detectors arranged about a touch area. The emitters are driven by a series of orthogonal functions, and the system is operable to correlate the signals received at the detectors with the modulation functions to determine the amount of energy received by the detectors from each of the emitters. This system means that all or many emitters can be modulated simultaneously, so the scanning process is accelerated. Also, the energy estimates arrived at by correlation with the modulating functions are largely unaffected by external interference signals as well by each other. An additional benefit of the present invention is that the correlation processing makes use of many detector samples and tends to yield results which have higher resolution than the sample values themselves, due to the averaging of noise over the sample set.

At least some of the photosensitive elements are at least partially transparent so that they selectively pass a second portion of the component to continue along the light path.

  • Patent number: 7723665
    Abstract: A method for calibration and/or compensation in transference of digital and/or analogue motion pictures to a photosensitive material comprises exposing a section of a photosensitive material by modulating light from a light source and imaging the modulated light onto the photosensitive material, develop the section of the photosensitive material, measure the characteristics of the developed film while illuminated by the said light source, and adjusting the light source and/or light modulation according to the measurement. By using the same light source for exposing and measuring the film, good reproducibility can be achieved, as well as a reliable basis for the adjustments.

  • Publication number: 20100038521
    Abstract: The use of rare-earth (REO, N, P) based materials to covert long wavelength photons to shorter wavelength photons that can be absorbed in a photovoltaic device (up-conversion) and (REO, N, P) materials which can absorb a short wavelength photon and re-emit one (downshifting) or more longer wavelength photons is disclosed. The wide spectral range of sunlight overlaps with a multitude of energy transitions in rare-earth materials, thus offering multiple up-conversion pathways. The refractive index contrast of rare-earth materials with silicon enables a DBR with >90% peak reflectivity and a stop band greater than 150 nm.

    Abstract: The invention relates to the detection of the position of a projection of an electromagnetic beam on a surface such as a laser pointer projection on a display screen. It is suggested to measure intensities of the electromagnetic radiation from the beam projection at three or more different positions at the borders of the surface and to process the measured intensities for determining the centre position of the electromagnetic beam projection on the surface. The intensities may be measured applying only a few low cost receivers.

  • Publication number: 20080067328
    Abstract: A spectrophotometer, in which an emission spectrum of the light source is measured. Based on the measured emission spectrum, a threshold is set to allow only an outstanding spectral intensity in a specific wavelength region to be greater than the threshold. Then, a ratio between the setup threshold and a peak spectral intensity in the specific wavelength region greater than the threshold is calculated. Then, an electric-charge accumulation time for a light-receiving element corresponding to a wavelength region equal to or less than the threshold is set at an upper limit of electric-charge accumulation time causing no saturation in any light-receiving element. Based on the ratio between the threshold and the peak spectral intensity in the specific wavelength region greater than the threshold, an electric-charge accumulation time for the light-receiving element corresponding to the specific wavelength region greater than the threshold is set.

    Abstract: In a six-axis force sensor, each optical displacement sensor comprises an optical module to emit a light and a reflecting member to reflect the light back to the optical module, such that the optical axis of the light from the optical module is aligned to the axial direction of the six-axis force sensor, rather than to the radial direction. Consequently, the six-axis force sensor can be downsized in the radial direction.

  • Patent number: 7135672
    Abstract: A flash ladar system has a laser provided with beam focusing optics for directing a laser fan beam pulse to a scanning element that in turn directs the laser fan beam to a vertical region of space. Light reflected from an object in the vertical region of space is directed by a reflecting element to a sensor provided with a column of photosensitive pixels that connects to a charge storage matrix of non-photosensitive pixels. After an integration period electrical charges are shifted from the photosensitive region to an adjacent column in the charge storage region. The process of integrate and shift is repeated for multiple integration periods until the charge storage region is filled with charges whereupon a serial shift register removes the information to be processed by a data processor.
