Abstract:
In an antenna, an antenna element interval is reduced without depending on an interval between converters, to widen the range of a phase folding angle to widen a detection angle range. The antenna includes a first antenna element including a feeder line extending from a first converter and a plurality of radiating elements. A second antenna element includes a feeder line extending from a second converter aligned together with the first converter and a plurality of radiating elements. The first and second antenna elements respectively include, at partial line portions of the feeder lines which extend from the converters to closest radiating elements, bend portions which are bent in directions which the bend portions come close to each other. The partial line portions of the first and second antenna elements are disposed so as to be linearly symmetrical about a virtual line.
Abstract:
A control device of a plasma ignition apparatus according to an embodiment includes a plug socket, an oscillation unit, and an amplification unit. The plug socket holds an ignition plug, and a high voltage generated by an ignition coil is transmitted to the ignition plug through the plug socket. The oscillation unit oscillates a high frequency. The amplification unit amplifies the high frequency oscillated by the oscillation unit. The oscillation unit is arranged outside of the plug socket and the amplification unit is arranged inside of the plug socket.
Abstract:
A drive recorder according to an embodiment includes a capture unit and an access controller. The capture unit captures an outside of a vehicle. The access controller sets access limitation, which limits an access from a person other than an occupant of the vehicle, for traveling images of the vehicle. The traveling images are captured by the capture unit and stored in a storage medium. When an event arising from the vehicle meets a predetermined condition that indicates at least level of urgency, the access controller removes the access limitation.
Abstract:
There is provided a radar device. A transmitting unit transmits a transmission signal in which an up period and a down period are repeated. A receiving unit receives reception signals from a target. A distance measuring unit computes the distance between the target and the radar device based on a reception signal corresponding to the up period, as an up-side distance, and computes the distance between the target and the radar device based on a reception signal corresponding to the down period, as a down-side distance. An aliasing determining unit determines whether velocity aliasing has occurred, based on the up-side distance and the down-side distance. A velocity measuring unit computes the relative velocity between the target and the radar device, based on the result of determination on velocity aliasing, and one of the reception signal of the up period and the reception signal of the down period.
Abstract:
An image processing apparatus determines a transparency percentage of each of plural portions of a cabin image of a vehicle, causes the plural portions to be semi-transparent or to be transparent at the determined transparency percentages and displays the cabin image. Thus, the user can intuitively understand a positional relationship between the vehicle and a surrounding region and does not miss an obstacle in a course of traveling of the vehicle.
Abstract:
A solenoid valve device according to an aspect of an embodiment includes a solenoid valve, a determination unit, a setting unit, and a correction setting unit. The solenoid valve is provided on a fluid channel with a fluid passing there through and adjusts a flow rate of the fluid. The determination unit determines a target degree of valve opening of the solenoid valve. The setting unit sets a driving signal for driving the solenoid valve in such a manner that a degree of valve opening of the solenoid valve is the target degree of valve opening. The correction setting unit sets a differential pressure correction signal for driving the solenoid valve in accordance with a differential pressure on the fluid channel between a front and a back of the solenoid valve.
Abstract:
In the case where the scheduled use start time has been acquired, the controller shortens the interval between the adjacent working time periods of the transceiver as the scheduled use start time approaches. Thus, in a case where there is a long time before the scheduled use start time, the power consumption is decreased. As the scheduled use start time approaches, the transceiver verifies the user immediately.
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:
A high frequency generating device used in a plasma ignition apparatus according to an embodiment includes a high frequency output unit, an output control unit, a current detecting unit, and an abnormality detecting unit. The high frequency output unit outputs a high frequency. The output control unit shifts a state of the high frequency output unit from a non-output state to an output-ready state of the high frequency. The current detecting unit detects a current that flows through a power-supply path to the high frequency output unit. The abnormality detecting unit detects output abnormality of the high frequency in the non-output state when a value of a current detected by the current detecting unit in the non-output state exceeds a non-output threshold.
Abstract:
An input device according to an embodiment includes an operation detection unit, at least one vibration element, a setting unit, and a vibration control unit. The operation detection unit detects a touch operation on an operation surface. The at least one vibration element vibrates the operation surface. The setting unit receives a setting where, at least, a content of the touch operation on the operation surface and a vibration parameter of the vibration element are associated with one another. The vibration control unit controls a vibration state of the vibration element based on the setting.
