Abstract: The image acquisition unit acquires a body image generated by capturing an image of a body of a target person when a target person is in a position away from an imaging unit by a first distance and acquires a code image generated by capturing an image of a code recording medium carried by the target person when the target person is in a position away from the imaging unit by a second distance shorter than the first distance. The authentication information generation unit starts processing for generating biometric information for authentication of the target person from the body image in accordance with the acquisition of the body image of the target person. The embedded information acquisition unit acquires embedded information from the code image. The authentication unit executes biometric authentication by collating biometric information for authentication with biometric information for registration included in the embedded information.

Abstract: A current sensor is configured to detect a current flowing through an electrical conductor. The current sensor includes a core and a coil wound around the core. The core has a hollow therein configured to allow the electrical conductor to pass through the hollow. The core substantially has a C-shape having a gap connected to the hollow. The core has a pair of end surfaces facing each other in a facing direction across the gap. The core includes plural split cores joined to one another. Each pair of split cores of the plural split cores adjacent to each other have respective joining surfaces joined to each other. The respective joining surfaces of the each pair of split cores being parallel to the facing direction. This current sensor has a desired sensitivity characteristic.

Abstract: A current sensor is configured to detect a current flowing through an electrical conductor. The current sensor includes a core and a coil wound around the core. The core has a hollow configure to allow the electrical conductor to pass through the hollow. The core substantially has a C-shape haying a gap connected to the hollow. At least a part of the gap of the core is located inside the coil. This current sensor suppresses the influence of external noise.

Abstract: Provided is an ATR prism, including a material having an internal transmittance of 90% or higher at a wavelength falling within a wavelength range of from 8 ?m to 10 ?m, when the material has a thickness of 2 mm. The ATR prism includes: a first surface including a first totally reflecting surface; a second surface including a second totally reflecting surface; and a recessed portion formed in one of the first surface or the second surface.

Abstract: A data communication device to provide can have stable communication quality. Data communication device according to the present disclosure includes a fitting surface and an outer surface opposite from the fitting surface. Data communication device also includes belt, buckle, a communication electrode, and a communication unit. Belt is joined to buckle. The communication electrode is formed at belt or buckle to be exposed at the fitting surface. The communication unit is electrically connected to the communication electrode. Buckle includes a buckle mechanism. Because of this structure, belt can be set to have a right length. Therefore, a reduced clearance can be achieved between the communication electrode and a human body when data communication device is put on.

Abstract: A massage apparatus includes a main frame and an air-bag for massage. The air-bag includes an air-bag front section and an air-bag main body fixed to the dorsal side of the air-bag front section. The air-bag is arranged that the dorsal side of the air-bag main body is disposed toward the main frame so that the front side of the air-bag front section makes up a contact side with a human body. The dorsal surface of the air-bag main body is configured to be able to expand and shrink, and the air-bag front section is configured so as to remain flat even when the air-bag main body is expanded or shrunken.
