摘要： A host unit in a wireless power transmission system transmits power to a secondary unit during a communication-directivity control period and a power transmission period that are temporally divided from each other. The host unit transmits power such that a transmission output power of a power transmission radio wave during the power transmission period is greater than a transmission output power of a communication signal during the communication-directivity control period.

摘要： Provide is a radio communication system suitable for use in a factory or the like. The radio communication system includes a receiver provided with a plurality of antennas, and a transmitter for periodically transmitting a radio signal for information transmission including information to be notified to the receiver, and the receiver is an information receiver. Based on the output of each antenna during a period in which the transmission radio signal is not transmitted, a weighting factor for each antenna is generated, and the generated weighting factor is used to process the radio signal for information transmission from the receiver.

摘要： A wireless communication apparatus is provided with: a signal receiving circuit configured to wirelessly receive a measurement value of a sensor from a slave apparatus; a position estimator configured to estimate a position of the slave apparatus; a storage device configured to store a history of the position of the slave apparatus; and a master control circuit configured to display the measurement value of the sensor and the position of the slave apparatus on a display device. When the master control circuit fails to receive the measurement value of the sensor from the slave apparatus, the master control circuit displays, on the display device, a latest position stored in the storage device, together with an error message indicating that communication between the wireless communication apparatus and the slave apparatus is interrupted.

摘要： A wireless communication device acquires, from a predetermined wireless slave device included in one or more wireless slave devices different from the wireless communication device, unrelated transmission information that is transmission information wirelessly transmitted to a master device, corresponding to the predetermined wireless slave device, in accordance with the predetermined time division multiple access scheme and that includes identification information identifying the predetermined wireless slave device, the unrelated transmission information being acquired at the time of the wireless transmission. On the basis of the identification information included in the unrelated transmission information, the acquisition time of the unrelated transmission information, and information relating to a transmission sequence, the wireless communication device determines a predetermined time slot for the wireless communication device to transmit the predetermined information to the master device corresponding thereto in accordance with the predetermined time division multiple access scheme; and transmits the predetermined information.

摘要： A power supply apparatus according to the present invention includes a power supply antenna, a directivity control unit, a position information acquisition unit, and a control unit. The power supply antenna emits, to a plurality of power reception apparatuses, a radio wave that is based on a power supply signal. The directivity control unit controls directivity of the power supply antenna. The position information acquisition unit acquires position information indicating a position of a moving obstruction. The control unit determines, based on the position information, a power reception apparatus, among the plurality of power reception apparatuses, to which power is supplied while avoiding the obstruction. The control unit controls the directivity control unit to steer the radio wave toward the determined power reception apparatus.

摘要： A wireless power transmitting apparatus is provided with: a power transmitting circuit for transmitting power for a load device to a wireless power receiving apparatus; a signal transmitting circuit for transmitting a control signal for the load device to the wireless power receiving apparatus; a signal receiving circuit for obtaining an estimated received power level indicating a level of the power transmitted from the wireless power transmitting apparatus and received by the wireless power receiving apparatus; and a control circuit. The control circuit periodically allocates time slots to wireless power receiving apparatuses for wireless power transmission. When the received power level is smaller than a threshold in a first time slot allocated to one wireless power receiving apparatus, the control circuit extends a second time slot allocated to the one wireless power receiving apparatus, the second time slot preceding or following the first time slot.

摘要： A sensor module that transmits at a predetermined transmission interval, via a network, data obtained by measurement to an externally installed information processing device sets, together with a nearby sensor module, a predetermined module group in which a plurality of sensor modules for transmitting measurement data according to data processing in the information processing device are put together. Then, together with the nearby sensor modules, one sensor module among the predetermined module group is set as a reference sensor module for which a transmission interval is maintained at a predetermined transmission interval, and transmission intervals of measurement data of sensor modules other than the reference sensor module are changed to a prolonged transmission interval that is longer than the predetermined transmission interval. With this, a reduction in power consumption is realized as much as possible in the sensor module that measures environmental parameters and transmits to the information processing device.
