Abstract: An air conditioning system includes: an outdoor unit including a first refrigerant circuit that includes a compressor and a first heat exchanger; a first indoor unit disposed in a first indoor space and that includes a second heat exchanger; a second indoor unit including a third heat exchanger; an intermediate unit including an intermediate refrigerant circuit that causes the second heat exchanger and the third heat exchanger to individually function as an evaporator or a condenser; and a first auxiliary refrigerant circuit including a first auxiliary heat exchanger and a second auxiliary heat exchanger connected in series to the first auxiliary heat exchanger via a refrigerant pipe.

Abstract: An air conditioning system includes: an outdoor unit that includes a first refrigerant circuit including a compressor, and a first heat exchanger; an indoor unit in a first space and that includes a second refrigerant circuit including a second heat exchanger; a liquid side pipe and a gas side pipe each connecting the first refrigerant circuit to the second refrigerant circuit; an outdoor air treatment unit including a first auxiliary refrigerant circuit including a first auxiliary heat exchanger connected to a first branching pipe branching from the liquid side pipe, and a second branching pipe branching from the gas side pipe, and a supply fan that supplies outdoor air having passed through the first auxiliary heat exchanger to the first space; a first shutoff valve on the first branching pipe; and a second shutoff valve on the second branching pipe.

Abstract: An optical touch panel includes: a pair of retroreflective plates that are arranged inside at least a left and right pair of frame portions facing each other in a rectangular frame; a plurality of detectors that are arranged at four corners of the rectangular frame, the detectors being configured to irradiate infrared rays to, at least, the retroreflective plates, and to generate detection images based on reflection light from the retroreflective plates; and an operation determining unit configured to detect a touch position based on the detection images generated by the detectors.

Abstract: A sub-pixel disparity cost volume which contains initial cost values of dissimilarity calculated between the pixel values on a standard image of a plurality of parallax images and the interpolated sub-pixel values on the counterpart image or images other than said standard image is prepared for a plurality of parallax images of objects in a three-dimensional structure composed of horizontal, vertical and disparity axes. Noise signals on the calculated cost values in the sub-pixel disparity cost volume are eliminated by using an edge-preserving filter which allocates bigger weights between two cost values whose pixel coordinates have similar pixel values on the standard image, for preserving edges or boundaries of the objects. A sub-pixel disparity is selected, which gives the minimum cost value in the specific disparity range around a previously-given initial pixel-wise or sub-pixel disparity at each pixel coordinate on the standard image.
