An image forming apparatus (1) includes an apparatus body, a first station (X4), second multiple stations (X1, X2, X3), a first image former (10K), second multiple image formers (10Y, 10M, 10C), a first air supply port (C4), second multiple air supply ports (C1, C2, C3), a first exhaust port (D4), second multiple exhaust ports (D1, D2, D3), an exhaust duct (42), and a sealer (51Y, 51M, 51C). The second multiple air supply ports (C1, C2, C3) supply air to the second multiple stations (X1, X2, X3), and the supplied air is exhausted from the second multiple stations (X1, X2, X3). The sealer (51Y, 51M, 51C) seals the second multiple exhaust ports (D1, D2, D3) when the second multiple image formers (10Y, 10M, 10C) are detached from respective stations. The sealer (51Y, 51M, 51C) includes a restrictor (51b) to restrict an attachment of the second multiple image formers (10Y, 10M, 10C).

An image forming apparatus includes a memory, a user interface, a network interface, and a controller. The image forming apparatus is connectable to the Internet via the network interface. The controller is configured to: perform communication via the network interface in accordance with a setting value stored in the memory; in response to receiving, via the user interface, an instruction to change the setting value stored in the memory, change the setting value in accordance with the instruction; perform communication via the network interface in accordance with the changed setting value stored in the memory; and control the user interface to display a warning regarding security degradation based on the received instruction.

A communication apparatus includes a processing circuit (21) and a storage apparatus (22). The processing circuit is configured to, when a state of a vehicle (40) is switched, apply a size of data set such that a first total amount of data becomes fixed regardless of the state of the vehicle (40) in a predetermined period, as a size of data to be transmitted by an own apparatus, when the size of the data to be transmitted is larger than the applied size, transmit the data after reducing the size of the data to the applied size, and when the size of the data to be transmitted is smaller than the applied size, transmit the data after providing data as padding to the data until the size of the data becomes the applied size.

A server 5 that can communicate with a vehicle 2 includes a transmission control unit 533 configured to control transmission of data acquired previously in the vehicle from the vehicle to the server, based on whether or not a user of the vehicle has given consent to providing data to outside at a time of acquiring the data in the vehicle, with reference to information received from the vehicle.

The temperature of a battery is raised by an electric heater. A planning unit of an ECU creates a temperature raising plan. A charge electric power amount fee unit price calculation unit calculates a charge electric power amount fee unit price. The temperature raising plan is created such that electric power of the battery is supplied to the electric heater in a time slot in which an electric power amount fee unit price of the external power supply is higher than the charge electric power amount fee unit price, and electric power of the external power supply is supplied to the electric heater in a time slot in which the electric power amount fee unit price is equal to or lower than the charge electric power amount fee unit price. A power controller supplies electric power to the electric heater based on the temperature raising plan.

A liquid discharge head (10) includes multiple nozzles (14a), a liquid channel (151), a supply tank (20), and a supply port (12). The liquid channel (151) communicates with the multiple nozzles (14a), to flow a liquid through the liquid channel (151). The supply tank (20) has a supply tank inlet (21) to supply the liquid from the liquid channel (151) into the supply tank (20) and a supply tank outlet (22) to discharge the liquid from the supply tank (20) to the liquid channel (151) toward the multiple nozzles (14a). The supply port (12) supplies the liquid to the supply tank inlet (21) through the liquid channel (151). The supply tank (20) is disposed between the supply port (12) and the multiple nozzles (14a) in the liquid channel (151). The supply tank inlet (21) is disposed below the supply tank outlet (22) in a gravity direction.

An information processing apparatus installed in a vehicle includes: a data storage control unit 334 configured to cause a vehicle storage unit 32 to store consent period information regarding a period in which a user of the vehicle consented to providing data acquired in the vehicle to outside; and a transmission control unit 335 configured to control transmission of data acquired previously in the vehicle to an external apparatus 5 based on whether or not the user consented to providing data to outside at a time of acquiring the data with reference to the consent period information.

A vehicle control apparatus (10) performs pre-collision control for reducing a collision probability that a vehicle (VA) collides with an object when the collision probability is high. The vehicle control apparatus prohibits performing the pre-collision control when an operation amount related to a steering operation of a steering wheel of the vehicle by a driver becomes greater than a first threshold value during the pre-collision control. The vehicle control apparatus continues to prohibit performing the pre-collision control when the steering operation satisfies a predetermined continuation condition, in a case where the operation amount is equal to or less than a second threshold value after prohibiting performing the pre-collision control.

Provided is a foldable projector. The foldable projector includes a projection module (1) and an auxiliary module (2). The projection module (1) and the auxiliary module (2) form a foldable structure that can be unfolded when used or folded when stored. With this arrangement, after the foldable projector is folded, the projection module (1) and the auxiliary module (2) can be attached and connected to each other to form a compact structure so that the foldable projector occupies a smaller volume, making it easier for a user to store and carry the foldable projector. Moreover, when the foldable projector is unfolded when used, the projection module (1) can rotate away from the auxiliary module (2) so that the auxiliary module (2) can avoid a heat dissipation route of the projection module (1), providing a sufficient space for the projection module (1) to dissipate heat.

A battery system includes a battery made of a lithium-ion secondary battery, a sensor group configured to detect a voltage, a current, and a temperature of the battery, and a control device configured to control a charging current of the battery based on detection values of the sensor group. The control device is configured to acquire a deterioration state of the battery from the detection values of the sensor group, and set a threshold voltage at which lithium metal is deposited on an electrode of the lithium-ion secondary battery with respect to the voltage of the battery, in accordance with the acquired deterioration state of the battery. The control device is configured to reduce, when the voltage of the battery exceeds the threshold voltage during charging of the battery, the charging current to a limit current.
