A foreign object removal device removes a foreign object on a vehicle-body undersurface of a vehicle traveling a road surface in wireless power transfer from a power transmission unit of a power transmission device installed on the road surface to a power reception unit of a power reception device mounted on the vehicle-body undersurface, and comprises a foreign object removal unit installed on the road surface around the power transmission unit and removing the foreign object on the vehicle-body undersurface.

Foreign object removal device and power transmission device

A communication control device comprises: an antenna; and a control unit that controls wireless communication related to wireless power transfer to a power receiver device through a power transmitter device. The control unit acquires via the antenna a radio wave status of each of a plurality of channels related to the wireless communication. The control unit acquires a power transmission status of the wireless power transfer. The control unit sets, based on the acquired power transmission status, switching conditions for switching the channel according to the radio wave status. The control unit causes the channel to be switched based on the radio wave status and the switching conditions. The control unit causes the wireless communication to continue on the switched channel.

Communication control device

A wireless power feeding apparatus () is configured to perform wireless communication with a power reception side apparatus () and to perform wireless power transmission to the power reception side apparatus. The wireless power feeding apparatus is provided with: a communicating device () configured to switch between a first communication method that allows one-to-many communication and a second communication method that has less communication delay than the first communication method, thereby performing the wireless communication; and a communication controlling device () configured to control the communicating device to switch from the first communication method to the second communication method and to perform the wireless communication in the second communication method, on condition that the wireless power feeding apparatus becomes in a state in which the power transmission can be performed, when the communicating device performs the wireless communication in the first communication method.

Wireless power feeding apparatus, communication method, and computer program

An image processing apparatus receives an input image signal and performs an enhancement process on a high frequency component included in the input image signal based on a low frequency component of the input image signal. The apparatus extracts a low frequency component from the input image signal and combines a step variation component of the input image signal with the low frequency component to generate a combined wave component. The apparatus performs an enhancement process on the high frequency component obtained by removing the combined wave component from the input image signal.
