Abstract: Main cells that constitute a semiconductor element having a trench gate structure include first cells, and second cells having a structure in which gate insulating films are more easily broken by energization than those in the first cells, and the number of which is smaller than that of the first cells. At a time of driving the semiconductor element, a common gate drive voltage is applied to gate electrodes of the first cells and the second cells. An electrical characteristic is measured to detect failure of the second cells due to energization at the time of driving. The gate electrodes of the failed second cells are electrically isolated from the gate electrodes of the first cells so that the gate drive voltage is not applied to the failed second cells. The failure of the first cells is predicted based on the failure of the second cells.

Abstract: A drowsiness estimating apparatus is provided with: an imager configured to take a face image of a driver of a vehicle; a detector configured to detect a duration of a mouth movement of the driver and whether or not the mouth movement has periodicity, on the basis of the face image; a determinator configured to determine a type of the mouth movement on the basis of the duration and whether or not the mouth movement has the periodicity; and an estimator configured to estimate drowsiness of the driver on the basis of the type of the mouth movement.

Abstract: Teaching disclosed herein is an apparatus comprising a support layer. The support layer may be adapted for supporting a heat generator, wherein the support layer includes a flow passage. The flow passage may seal working fluid therein. The flow passage may extend along a thickness direction of the support layer.

Abstract: A MEMS device includes a substrate, a moving part including a magnetic material and configured to tilt relative to the substrate, a first magnetic pole and a second magnetic pole configured to apply a magnetic field to the magnetic material, and a magnetic field detector configured to detect the magnetic field of the magnetic material. In the MEMS device, the first magnetic pole and the second magnetic pole are disposed on one side of the moving part, the one side being a side on which the magnetic material is located. The magnetic field detector is disposed between the first magnetic pole and the second magnetic pole. A distance between the first magnetic pole and the second magnetic pole is shorter than a length of the moving part in a direction from the first magnetic pole toward the second magnetic pole.

Abstract: An alerting illumination device, which includes a detecting component, a danger degree estimating component, a danger assuming component, an illuminating component and a controlling component, is provided. The danger degree estimating component estimates a degree of danger, with respect to a subject vehicle, of the person detected by the detecting component. The danger assuming component, on the basis of the estimated degree of danger, assumes whether or not the person detected by the detecting component is a danger with respect to the subject vehicle. The illuminating component illuminates light. The controlling component, in a case in which the danger assuming component assumes that the person is a danger, controls the illuminating component such that light, which shows a direction of the person who is assumed to be a danger and a distance to the person, is illuminated onto a road surface.
