A movable structure includes: a moving part pivoting about a predetermined axis; a sensor module provided at the moving part or at a site interlocked with the moving part; and a control device controlling the moving part and the sensor module. The control device controls the moving part in such a way that the sensor module takes a first attitude, and gives a calibration instruction to the sensor module. The sensor module includes: an inertial sensor; a calibration unit calculating an attitude of the sensor module based on an output signal from the inertial sensor in response to the calibration instruction and generating correction information based on a difference between the calculated attitude and the first attitude; and a correction unit correcting the output signal from the inertial sensor, based on the correction information.

A sensor unit includes a first sidewall, a second sidewall, a third sidewall connected to one end of the first sidewall and one end of the second sidewall, and a fourth sidewall opposed to the third sidewall of a container including a lid, a first connector, and a second connector. The first connector is attached to the first sidewall further on the side of the fourth sidewall than the side of the third sidewall. The second connector is attached to the second sidewall further on the side of the third sidewall than the side of the fourth sidewall.

Sensor unit, construction machine, and structure monitoring device

A sensor unit includes a substrate, an inertial sensor module mounted at the substrate, a container including a storage space for storing the substrate and the inertial sensor module, and a coupling member that couples the container and the substrate in a state in which the substrate and the container are in non-contact with each other. The coupling member has elasticity, and an elastic modulus of the coupling member is smaller than an elastic modulus of the container.

There is provided a power transmission control device included in a power transmission device in a contactless power transmission system that transmits power from the power transmission device to a power receiving device by electromagnetically coupling a primary coil to a secondary coil to supply the power to a load of the power receiving device. The power transmission control device includes a controller controlling the power transmission control device, a host interface communicating with a power transmission-side host, and a register section accessible from the power transmission-side host via the host interface. The controller shifts into a communication mode that executes communication between the power transmission-side host and a power receiving-side host, when the power transmission-side host writes, via the host interface, a communication request command that requests the communication between the hosts in the register section. Then, the controller transmits the communication request command to the power receiving device.

A contactless power transferring coil unit is provided. The contactless power transferring coil unit includes a flat coil, a magnetic film, and a leaking flux detecting coil. The flat coil is formed by winding a conductive wire into a spiral on a substantially flat plane. The magnetic film is disposed so as to cover one entire flat surface of the flat coil. The leaking flux detecting coil is disposed in a periphery outside an outer edge of the flat coil and the magnetic film and detects leaking magnetic flux from the flat coil.

A power reception device utilizing non-contact power transmission causes a PMOS transistor as a switch circuit to be turned ON when a secondary battery is in a heavy-load state to form a path which bypasses a series regulator (LDO) as a power supply circuit, and supplies a charging current to the secondary battery through the bypass path. An offset may be provided between ON/OFF control threshold values of the PMOS transistor. The series regulator (LDO) may be entirely or partially set in a non-operating state when forming the bypass path.

A power receiving control device provided to a power receiving device in a contactless power transmission system that transmits power from a power transmission device by electromagnetically coupling primary and secondary coils to feed electric power to a load. The power receiving control device includes a power receiving side control circuit. The power receiving side control circuit turns on a switch circuit provided between input and output nodes of a regulator in the power receiving device based on detecting lowering power feeding capability. The power receiving side control circuit turns off the switch circuit when power feeding is temporarily stopped in a period when the regulator is bypassed when voltage of a power supply control signal output terminal switches levels or before the power feeding is temporarily stopped. The power receiving side control circuit turns on the switch circuit after releasing the temporary stop of power feeding.
