Abstract: A signal processing device includes: a processor; and a memory having instructions. When executed by the processor, the instructions cause the signal processing device to perform operations including: converting a first signal that is a time domain signal into a second signal that is a frequency domain signal in response to reception of the first signal, the first signal containing noise superimposed on a broadcast electric signal derived from a broadcast electromagnetic wave, the noise having peaks of amplitude at regular frequency intervals in the frequency domain; calculating a frequency interval between the peaks of the noise in the frequency domain based on a correlation of the second signal; determining a frequency shift amount in the frequency domain based on the frequency interval; and shifting a frequency of the second signal by the frequency shift amount to create a frequency-shifted signal.

Abstract: A control apparatus to be mounted on a vehicle includes one or more processors, and one or more memories each storing a program to be executed by the one or more processors. The program includes one or more commands. The one or more commands are each configured to cause the one or more processors to: determine whether the vehicle is in an enclosed environment; and execute abnormality notification control to output an abnormality notification based on a result of a power-source-state determination and a result of a presence determination when the one or more processors determine that the vehicle is in the enclosed environment. The power-source-state determination is a determination regarding a state of a power source of the vehicle, and the presence determination is a determination as to whether there is a person inside or outside the vehicle.

Abstract: A vehicle battery pack for an electric vehicle includes a battery, a battery-cooling-air channel, a fume exhaust channel, a fume-ventilation restricting unit, a temperature sensor, a blower fan, and a controller. Cooling air that cools the battery flows through the battery-cooling-air channel. Fumes generated from the battery flow through the fume exhaust channel. The fume exhaust channel is coupled to the battery-cooling-air channel. The fume-ventilation restricting unit closes off the fume exhaust channel from the battery-cooling-air channel in a normal state, whereas causing the battery-cooling-air channel and the fume exhaust channel to communicate with each other in an abnormal state. The temperature sensor detects a temperature of the fumes. The controller controls the blower fan, and increase the air volume of the blower fan on the basis of the temperature detected by the temperature sensor.

Abstract: A method of controlling an electromagnetic relay includes supplying a first voltage to an exciting coil to bring a movable terminal into contact with a fixing terminal; causing a coupling state determination unit to determine that a coupling failure is detected in a case where the movable terminal is not brought into contact with the fixing terminal and the electromagnetic relay is not turned on despite the supplying the first voltage to the exciting coil; and supplying a second voltage higher than the first voltage from a booster circuit to the exciting coil in a case where the coupling state determination unit determines that the coupling failure is detected. The second voltage is generated by boosting the first voltage by the booster circuit.

Abstract: A noise suppression structure to be mounted on a cooling system for an electrical device of a vehicle includes a duct, a blower, and a sound absorber. The duct extends from inside a vehicle cabin of the vehicle to inside the vehicle cabin or outside the vehicle cabin through the electrical device. The blower is configured to draw air from the vehicle cabin into the duct and feed the air to the electrical device. The sound absorber is disposed in the duct. The duct has a curved portion where an extension direction of the duct changes. The curved portion is located on one of or each of an upstream side and a downstream side of the electrical device. The sound absorber is disposed in a fluid stagnation region where a flow of the air tends to stagnate in the curved portion.

Abstract: A cutter is described for cutting through an article, such as an envelope, at a given distance from its edge, approximately straight and parallel to the edge. An edge portion of the article to be cut, such as an envelope, is positioned on a floor, and then it is slid with its edge in contact with a sliding side surface perpendicular to the floor. The thing to be cut is pressed against the sliding surface with a press means when cut and slashed with a blade edge at a given distance from the envelope edge approximately straight and parallel to the edge.
