Abstract: Terahertz wave detection equipment comprises: a terahertz wave transceiver including a transmitter for transmitting a terahertz wave and a receiver for receiving a reflected terahertz wave reflected by a background reflected object which exists behind an object to be analyzed; a display; and an information processing apparatus, wherein the transmitter irradiates a terahertz wave based on a transmission signal including a specific frequency toward a two-dimensional area including the object to be analyzed, and the information processing apparatus is configured to analyze concentration of the object to be analyzed based on the reflected terahertz wave and generate a composite image in which a concentration image of the object to be analyzed is combined with an image of the background reflected object.

Abstract: A modulator of a distance measuring sensor unit 102 has a photographing pattern that includes a plurality of patterns different from each other, and modulates intensity of light. A gesture detecting unit divides image data obtained by receiving light transmitted through the modulator by the image sensor; restores an image by calculation based on a developing pattern corresponding to the photographing pattern in a divided unit; and obtains an image for detecting gesture of a user. This makes it possible to obtain an image of an object in an outside world without using a lens for forming an image. Therefore, it is possible to reduce a load on a user when the user wears the apparatus.

Abstract: A contactless power receiving device includes a power receiving coil receiving power from a contactless power transfer device, a rectifier circuit rectifying the power to form a rectified output on a high potential side and a rectified output on a low potential side, a smoothing circuit receiving the rectified output on the high potential side and the rectified output on the low potential side, and a switching power supply converting a DC voltage from the smoothing circuit to a first voltage. The smoothing circuit includes a first inductor transmitting the rectified output on the high potential side, a second inductor transmitting the rectified output on the low potential side, and a smoothing capacitance element to which the rectified output on the high potential side and the rectified output on the low potential side are supplied, and the rectified output on the low potential side is connected to a ground potential.
