Abstract: An estimating unit 51 estimates the upper limit of possible temperatures in a predetermined position of ICT equipment when the quantity of intake air into the ICT equipment is appropriate, based on the result of detection by an operational status detecting unit that detects the operational status of the ICT equipment and the result of detection by an intake-air temperature sensor 62 that detects the temperature of intake air of the ICT equipment. A determining unit 52 determines that an abnormality is occurring when the result of detection by a temperature sensor 63 that detects the temperature in the predetermined position is beyond the upper limit estimated by the estimating unit.

Abstract: One or more mechanical parameters of a structure subjected to a force or condition are measured using distributed, optical fiber sensing technology. At least a curved portion an optical fiber having is attached to an object. A distributed, optically-based, strain sensing technique is used to determine strain information associated with multiple points along the curved portion of the fiber. The determined strain information is processed to generate one or more representations of one or more of the following: an expansion of the object, a thermal gradient associated with the object, or a stress-induced strain at multiple locations on the object corresponding to ones of the multiple points. An output is generated corresponding to the representation.

Abstract: The accuracy of a measurement value obtained by a tire pressure detection device is lowered by a centrifugal force and an inertial force during travel. A pressure sensor (30) displaces a diaphragm (20) in its vertical direction (32) according to the pressure. The pressure sensor (30) is arranged in a tire (2) with the vertical direction (32) directed to a direction parallel to a rotation axis (34) instead of the tire circumferential direction or radial direction. The pressure sensor (30) is mounted onto a substrate with the vertical direction (32) of its diaphragm (20) directed in parallel to the substrate surface and the substrate is bonded to a tread portion of the tire (2) and a wheel rim portion while adjusting the vertical direction (32) of the diaphragm (20) with the direction of the rotation axis (34).
