A mobile terminal that performs communication with an onboard device includes: a communication control unit configured to control reception of information instructing to switch a sound source which is transmitted from the onboard device, the information including information indicating an application program which is executed in the terminal serving as the sound source, and transmission of a sound, played by an application program operating in a foreground of the terminal, to the onboard device; a switching unit configured to switch an application program having been in operation in a foreground until immediately before, to a background, on the basis of the received information instructing to switch a sound source, and to switch an application program having been in operation in a background until immediately before, to a foreground; and a sound control unit configured to stop playing a sound of the application program having been in operation in a foreground until immediately before, and to start playing a sound of the application program having been in operation in a background until immediately before, subsequently to the stop.

Mobile terminal, onboard device, control method, and control program

A frequency control apparatus includes: an input operation unit which detects a presence/absence of an input of a predetermined operation by an operator; and a control unit which, when the input of the predetermined operation by the input operation unit is detected, calculates radio frequencies, each of the radio frequencies being where a minimum value of differences with respect to multiplied frequencies of a current drive frequency of a device is less than or equal to a predetermined value, and which changes the current drive frequency of the device so that minimum values of differences between the calculated radio frequencies and multiplied frequencies of the changed drive frequency are greater than or equal to a predetermined value. The control unit changes the drive frequency to lessen a change width before and after the change by either increasing the drive frequency or decreasing the drive frequency.

Frequency control apparatus

A contactless power transmission device which transmits electric power in a contactless way includes: a power transmission section which transmits electric power using a primary coil; a power receiving section which is provided in a radio communication device and receives electric power using a secondary coil that is electromagnetically coupled with the primary coil; a housing which shields an electromagnetic wave, in which the power transmission section is provided, and which forms a closed space where the radio communication device is housed; and a housing antenna section which is provided in the housing and transmits a first communication signal to the outside of the housing, or transmits a second communication signal to the inside of the housing, the first communication signal being emitted from the radio communication device housed inside the housing, the second communication signal being emitted from the radio communication device housed outside the housing.

Contactless power transmission device provided in a vehicle for charging an electronic device

In a communication network having a first electronic control unit, a second electronic control unit, a transmission path connecting them, and a third electronic control unit connected to a branch path and communicatable with the first and second electronic control units that are each terminated with a termination circuit designed in accordance with a characteristic impedance of the transmission path, it is configured to comprise a connector that is connected to a connection point mounted on a circuit board in which the third electronic control unit is installed so that the third control unit is connected to the branch path via the connector and a conducting wire for removing a waveform distortion connected to the branch path via the connector at one end.

Wave form distortion removing apparatus for a communication network

A vehicular power transmission device includes a power transmission unit which transmits electromagnetic waves to a mobile device to transmit power to a power reception unit of the mobile device, and a frequency changing unit which, when it is determined based on the transmission frequency of the electromagnetic waves to be transmitted from the power transmission unit to the mobile device and a reception frequency of a radio receiver that radio noise is generated by the power transmission unit, changes the transmission frequency of the electromagnetic waves of the power transmission unit, wherein the power transmission unit changes a transmission power of the electromagnetic waves based on an amount of change in the transmission frequency of the electromagnetic waves changed by the frequency changing unit.
