摘要： A capacitance detecting circuit includes a code generator for generating code having orthogonality in chronological order. A column-line driver drives the plurality of column lines based on the code by dividing the column lines into a first column line group and a second column line group. A capacitance detector, which is connected to the row line, converts the total of currents generated in capacitances at the intersections with the driven column lines into a voltage signal and outputs the converted voltage signal. A decoding computation unit determines the voltages corresponding to the capacitances at the intersections for each of the column line groups by performing product sum computation between the measured voltages and the code. The column-line driver drives the first column line group and the second column line group by complementary voltages according to the code or information indicating the inversion of the code.

摘要： A light-emitting diode device includes a light-emitting diode, a lens cap made of synthetic resin, for covering the light-emitting surface of the light-emitting diode means, and a refractive layer formed between the light-emitting surface and the lens cap, the refractive layer having a composition, such as an air layer, with a refractive index different from the refractive index of said synthetic resin. In this arrangement the relationship between the light intensity and directional angles is shown by characteristics in which the light intensity is maximum in the center of the directional angles, and is relatively flat in the form of a sinusoid in the wide range of the directional angles. Therefore, even when the characteristics of each light-emitting diode is not verified, a predetermined light-signal transmission range is readily obtained without being affected by a scatter in the characteristics.

摘要： According to the present invention there is provided a space coordinates detecting device wherein a detecting section for detecting light emitted from a light source is provided, thereby permitting detection of a relative angle between a light emitting sections and the detecting section and hence permitting application of the detecting device to an input apparatus. The detecting section is provided with a light sensing element 23 having quartered light sensing portions. In the light emitting section, distinguishable lights are emitted from two light sources. The lights thus emitted are throttled through apertures and applied as separate square light spots S16 and S17 to the light-sensitive surface of the light sensing element 23. By calculating a difference in the detected output among the quartered light sensing portions, it is possible to determine the center I1 of the square light spot S16 and the center I2 of the square light spot S17. A relative rotational angle of the light emitting section and the detecting section with respect to Z axis can be determined by calculating an inclination angle .alpha. on X-Y orthogonal coordinates of a line x connecting both centers I1 and I2.

摘要： A remote coordinate designating device has a remote control with a light emitting device for emitting light, and a controller for detecting a designated position by receiving light from the remote control at a distance from the remote control. One cycle of a light signal from the light emitting device is composed of switch data and a coordinate detection timing header at the head, and a coordinate detection carrier. The switch data and the coordinate detection timing header use the same frequency as the normal remote control frequency band, and the frequency of the coordinate detection carrier is lower than the frequency of the switch data and the coordinate detection timing header. The switch data contains on-off information about a switch for pointing, and coordinate detection is started when a predetermined time has passed from the rise of a burst portion in the switch data.

摘要： A pressure-sensitive capacitive sensor includes a sensing unit in which a plurality of column wires and a plurality of row wires are formed in a matrix, a detecting signal generator, and filters. Capacitances at intersections between the column wires and the row wires change in accordance with externally applied pressure. The detecting signal generator sequentially outputs pulse signals of a predetermined frequency to the column wires of the sensing unit. The filters are connected to the respective row wires of the sensing unit and extract amplitudes of signals of the predetermined frequency. The amplitude is proportional to the capacitance at the intersection.
