Abstract: A radar apparatus derives (i) first target information of a first target existing in the transmission range of the transmission wave, the first target being a rear end portion of a vehicle and (ii) second target information of a second target existing in the transmission range of the transmission wave, the second target being a portion of the vehicle other than the rear end portion of the vehicle. The radar apparatus calculates a distance difference between the first target and the second target, and predicts, in a case where the first target information of the first target derived in a previous target information derivation process is not derived in a latest target information derivation process, a position of the first target, using the distance difference and the second target information of the second target derived in the latest target information derivation process.

Abstract: An information processing device according to an embodiment includes a memory and a mediation unit. The memory includes memory use areas that are allocated to respective tasks, and an identification-information area that identifies the tasks. The mediation unit mediates writing and reading, by one of the tasks, into and from one of the memory use areas. When accepting a request of the writing and reading from the one task, the mediation unit writes one of the identification informations corresponding to the one task into the identification-information area, further reads information memorized in the identification-information area at a predetermined timing, and detects an abnormality in the memory on the basis of the read information.

Abstract: A first roof extends over and covers an area above an aperture through which an input connector is accessible, so as to receive water drops flowing down along a side surface of a case. A first reinforcement reinforces a fixture by which the case is fixed to a fixed surface. The first roof and the first reinforcement are a single piece of material. Thus, since the first roof and the first reinforcement are the single piece of material, if the first roof is provided to the case, there is no need to form the first roof and the first reinforcement separately. Therefore, it is possible to prevent generation of additional mold production cost and material cost for the first roof.

Abstract: An image generation apparatus includes an image processor and a detector. The image processor generates a composite image viewed from at least one virtual viewpoint, and outputs the generated composite image to a display. The detector detects an indication of a driver intention to drive the host vehicle to a right or to a left relative to a travelling direction of the host vehicle. The image processor generates the composite image viewed from a virtual viewpoint located in front of the host vehicle in the travelling direction, the composite image showing a lateral surface of the host vehicle on a side corresponding to the detected indication of the driver intention. Thus, it is possible to make it easier to check a situation at a time of a right turn, a left turn, or a travelling direction change.

Abstract: A driving assistance system includes a history storage unit, a behavior detecting unit, a state determining unit, and a notifying unit. The history storage unit stores a behavior history which is a past behavior history of a driver. The behavior detecting unit detects a current behavior of the driver. The state determining unit determines an unsafe state by comparing the transition of the behavior detected by the behavior detecting unit with the behavior history of the driver corresponding to a current driving path. If the state determining unit determines the unsafe state, the notifying unit gives notification to the driver.

Abstract: A power-supply monitoring device includes a capacitor that is connected to an insulated electric power source to execute charging/discharging. A power-supply monitoring device including this capacitor forms a charging path for detecting deterioration in an insulation resistance of an electric power source, and detects a voltage of the capacitor when being charged through this charging path. A vehicle controller specifies an abnormal part based on whether or not the voltage of the capacitor detected by the power-supply monitoring device is within a predetermined range.

Abstract: A speaker includes a first vibrator, a first driving unit, a second vibrator, a second driving unit and a supporting unit. The first vibrator is connected to a diaphragm, which vibrates, thereby emitting sound. The first driving unit vibrates the first vibrator, thereby vibrating the diaphragm. The second vibrator is connected to a weight member. The second driving unit is connected to the opposite side of the first driving unit to the first vibrator, and vibrates the second vibrator on the same vibration axis as the vibration axis of the first vibrator, thereby vibrating the weight member. The supporting unit supports a coupled body, configured by joining the second vibrator and the weight member, at two or more portions in the direction of the vibration axis.

Abstract: An image processing apparatus includes a detector, an estimator and a determiner. The detector detects a candidate region of a captured image captured by a camera, the candidate region serving as a candidate for a water drop region affected by a water drop on the lens of the camera, based on an edge strength of each pixel in the captured image. The estimator estimates, based on the candidate region, a circle that includes the candidate region. The determiner determines whether or not the candidate region is part of the water drop region based on the edge strength of some of the pixels in the circle.

Abstract: An input apparatus according to the present embodiment includes a detector, a vibration element, and an element controller. The detector detects a touch on an operation surface. The vibration element vibrates the operation surface. The element controller reduces or stops a vibration of the vibration element based on a continuation time of the touch that is detected by the detector in a state where the operation surface is being vibrated.
