Abstract:
According to one embodiment, a structure evaluation system includes an impact imparting unit, a plurality of sensors, a position locator, and an evaluator. The impact imparting unit applies impacts to a second region different from a first region of a structure to which traveling sections of a vehicle, which travels on the structure, apply impacts. The plurality of sensors detect elastic waves generated in the structure. The position locator locates a position of a source of the elastic waves on the basis of the elastic waves detected by each of the plurality of sensors. The evaluator evaluates a deterioration state of the structure on the basis of a position location result of the position locator.

According to one embodiment, an electronic apparatus includes, for example, a casing having an opening with a perimeter, and a circuit board including a first surface facing away from the casing and a second surface facing the casing, a first conductor which extends over the opening in the casing and at least a portion of which is located over the first surface, a second conductor at least portion of which extends over the second surface and is exposed to the interior of the casing at the opening in the casing, and a third conductor extending through the first surface and the second surface and electrically connected to the first conductor and the second conductor at a location outward of the perimeter of the opening.
Abstract:
According to one embodiment, a structure evaluation system includes at least three or more sensors, a position locator, and an evaluator. The three or more sensors are arranged on surfaces different from a surface to which an impact is applied with respect to a structure at different intervals in a first direction of the structure and a second direction orthogonal to the first direction and detects elastic waves generated from the structure. The position locator locates a position of a source in which the elastic waves are generated on the basis of the elastic waves detected by each of the three or more sensors. The evaluator evaluates a deterioration state of the structure on the basis of information based on a position location process of the position locator and information indicating a position where the impact is applied.
Abstract:
According to one embodiment, a vibration detecting device includes a housing, a vibration sensor in the housing, a circuit board in the housing, a flexible wiring component, a first face, and a second face. The vibration sensor is housed in the housing. An electric component that processes a detection signal of the vibration sensor is provided on the circuit board. The wiring component electrically connects the vibration sensor and the circuit board. The first face is provided on the housing and is configured to be attached to an object. The second face is provided inside the housing and is inclined with respect to the first face, the vibration sensor being attached thereto.
Abstract:
A semiconductor device includes a housing, a substrate housed in and fixed to the housing, and a semiconductor module package disposed on a surface of the substrate. A protrusion is formed on the housing, protrudes towards the substrate, located adjacent to the semiconductor module package, and directly or indirectly urges the substrate in a direction away from the protrusion.
