Abstract: A cooling fan control device controls an operation of a cooling fan connected to a control microcomputer by communicating with the control microcomputer, and includes a control table reading unit to read a control table in which a control characteristic of the cooling fan is described, the control table being stored in the control microcomputer, a control table storage unit to store a content of the control table read by the control table reading unit, a control parameter acquisition unit to acquire an ambient temperature and a fan speed of the cooling fan that are in association with each other from the control microcomputer, and a control command unit to output a control command for controlling the cooling fan to the control microcomputer based on the ambient temperature and the fan speed acquired by the control parameter acquisition unit, and based on the control table.

Abstract: A contactless power feeding device for charging a battery disposed on a cart by contactless power feeding includes a plurality of first power feeding units in a row along a first direction. Each includes a power transmitter configured to transmit electric power to a power receiver attached to a cart. The device has plurality of tracks along which wheels of the cart move, and a housing connected to the one of the first power feeding units located at an end of the row. The housing includes a surface that serves as an end of each of the tracks. A first relay board is in the housing and configured to relay electric power from an external power supply to the plurality of first power feeding units.

Abstract: A cart POS control board according to an embodiment includes a storing unit and a control unit. The storing unit stores, in association with each other, identification information of a battery that may receive power supply and setting concerning control for the battery. If identification information of the battery acquired by an acquiring unit is stored in the storing unit, the control unit controls the battery according to setting associated with the identification information.

Abstract: Provided is a wireless communication module that is attached to peripheral equipment that is used together with an information processing apparatus and operates by electric power of which supply is different from supply of electric power to the information processing apparatus, the module including: a wireless communication unit configured to enable wireless communication between the information processing apparatus and the peripheral equipment; and a power source control processing unit configured to transmit a control signal that causes a circuit which receives electric power supply to be switched from one of an open state and a closed state to the other, to the peripheral equipment, according to a request that is received from the information processing apparatus.

Abstract: In accordance with an embodiment, a device connection unit capable of connecting the peripherals related to a commodity sales processing carries out a data transmission/reception with an information processing terminal if the information stored in the information processing terminal is consistent with that stored in a storage medium accessing the device connection unit.

Abstract: A commodity sales data processing apparatus includes a power supply unit configured to switch a power supply source for a control circuit to an auxiliary power supply when power supply from the outside is stopped and a movement detecting unit configured to detect the movement of a main body of the commodity sales data processing apparatus. The commodity sales data processing apparatus causes an alarming unit to generate an alarm according to the switch of the power supply source for the control circuit to the auxiliary power supply by the power supply unit and the detection of the movement of the main body by the movement detecting unit.
