  • Patent number: 8878718
    Abstract: A normalization processing circuit normalizes a position of a complex demodulation signal on a complex plane from an A/D converter, and outputs a normalized complex demodulation signal after the normalization to a multiple-dimensional feature extractor. The multiple-dimensional feature extractor calculates a feature quantity that changes when a person intrudes, a feature quantity that changes in wind and rain, and a feature quantity that changes when a spatially isolated intense electric field exists. A discriminator discriminates that a person has intruded based on the feature quantities of three dimensions.

  • Patent number: 7697106
    Abstract: A liquid crystal display device of the present invention has a structure in which vertically aligned liquid crystal is sealed between a TFT substrate and a CF substrate. Pixel electrodes in which slits are provided are formed on the TFT substrate, while cell gap holding spacers and domain defining projections are formed on the CF substrate. For example, positive type photoresist is coated on a common electrode. Then, first exposure is executed by using a mask for light-shielding spacer forming regions and projection forming regions, and then second exposure is executed by using a mask for light-shielding the spacer forming regions. Then, the photoresist is developed. Accordingly, the spacers and the projections, each having a different height, can be formed simultaneously.

  • Patent number: 7079669
    Abstract: An image processing apparatus detecting a wheelchair passenger for an elevator. This image processing apparatus includes a TV camera installed so that a hail where passengers are waiting is monitored through the camera, which is located in the vicinity of the elevator door, a face area extraction unit, a wheelchair area estimation unit, and a wheelchair existence judgment unit. The image processing apparatus is operated in the following manner, one or a several passengers' face area is identified by the face area extraction unit in the image picked-up by the TV camera, and the position of the face area in the image is detected. If the passenger is sitting in a wheelchair, the area where the wheelchair is likely to be in the image is estimated by the wheelchair area estimation unit from the position of the face area. The estimated area where the wheelchair is likely to be is checked by the wheelchair existence judgment unit, to determine whether the wheelchair is present.
