Abstract: Safety around a vehicle can be improved when there is a disagreement between an operation state of the vehicle and the notification contents notified from the vehicle. Abnormality notifying apparatus includes a determiner that determines whether or not there is a disagreement in correspondence relationship between operation control and notification control based on a first signal related to the operation control of vehicle and a second signal related to the notification control for notifying notification information according to the operation control to outside vehicle. When there is a disagreement in correspondence relationship, abnormality notifying apparatus notifies information indicating that the vehicle is in an abnormal state to outside vehicle.

Abstract: During a dead time, a resonance current generated by a load current that flows in a resonance inductor and a resonance current generated by an excitation current of a transformer flow in a resonance circuit constituted by the resonance inductor and capacitors that exist in parallel to respective switching elements. A controller performs a turning off operation on the switching elements at a timing that the resonance current generated by the load current and the resonance current generated by the excitation current are cancelled each other during the dead time.

Abstract: Provided are an information processing apparatus, an information processing method, and a recording medium that allow a pedestrian or a bicycle to cross a crosswalk pattern projected by a vehicle more safely. The information processing apparatus includes: a controller that controls a notification to be made by a notification apparatus that prompts a notification target person to cross; and an intention discriminator that discriminates an intention of crossing of the notification target person with respect to the notification. The controller controls the notification apparatus to stop the notification in a case where the intention discriminator discriminates that the notification target person has no intention of crossing.

Abstract: A signal processing apparatus for a tool including a rotating body rotated by impacts delivered from a drive apparatus is provided with: a filter a calculation circuit and a control circuit. The filter receives a torque value signal indicating a torque applied to the rotating body, and filters the torque value signal. The calculation circuit sets a filter coefficient of the filter based on a number of impacts delivered to the rotating body. The control circuit controls the impacts delivered to the rotating body, based on the torque value signal filtered by the filter.

Abstract: A contactless power feeding system includes: a primary circuit for supplying primary power to a power feeding coil; and a primary control circuit for controlling the primary circuit. The primary control circuit acquires, from a secondary control circuit, a secondary measured value and a secondary target value of secondary power received by a power receiving coil. The primary control circuit performs control processing and update processing alternately and repeatedly. The control processing is processing of controlling the primary circuit to bring the primary measured value into conformity with a primary target value. The update processing is processing of updating the primary target value. The update processing includes processing of calculating the primary target value based on transfer efficiency to be determined by the primary measured value and the secondary measured value and on the secondary target value.

Abstract: A power conversion system includes a power conversion device, a connector, and a processing module. The power conversion device is connected to a power system. The attached state and the unattached state of the connector relative to a connecting port that is provided in an apparatus having a battery mounted therein can be selected. The processing module is configured to determine that a malfunction has occurred when a voltage is applied to a portion that electrically connects the connector and the connecting port in a period in which transmission of electric power with respect to the battery is stopped.

Abstract: A control circuit is configured to adjust a phase difference which is a delay of the phase of each of the second drive signals to the phase of each of the first drive signals to a set value within a prescribed range to adjust the magnitude of output power. The control circuit includes an estimator and a setter. The estimator estimates whether an initial mode which is an operation mode of an inverter circuit in the case of a variable capacitance circuit being disabled is a leading phase mode or a lagging phase mode while the variable capacitance circuit is operating. The setter sets the prescribed range in accordance with the initial mode estimated by the estimator.
