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 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： A wireless communication device, a wireless information collection system, and a wireless communication method are provided. The wireless communication device is configured to wirelessly transmit predetermined information provided therein to its master device in a predetermined transmission cycle and executes the wireless transmission in a time slot of itself according to a predetermined time division multiple access scheme together with one or more wireless slave devices including at least a reference wireless slave device. First unrelated transmission information including reference transmission time information wirelessly transmitted from the reference wireless slave device to its master device in the predetermined time division multiple access scheme is acquired during the wireless transmission and a time counted by an internal timer unit is corrected based on an amount of correction calculated from an acquisition time of the first unrelated transmission information and the reference transmission time information included in the first unrelated transmission information.

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 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 power estimator calculates first estimated power values based on levels of test signals received from power receiver apparatuses, each first estimated power value indicating estimated received power of a corresponding power receiver apparatus when a power transmitter apparatus transmits power to the power receiver apparatuses. A signal transmitting circuit transmits each first estimated power value to a corresponding power receiver apparatus. A signal receiving circuit receives second estimated power values from the power receiver apparatuses, each second estimated power value indicating estimated received power of a corresponding power receiver apparatus when other power transmitter apparatuses transmit power to the power receiver apparatuses. A power transmitter control circuit determines pairing of the power transmitter apparatuses and the power receiver apparatuses for power transmission, based on the first and second estimated power values, so that estimated received power of each power receiver apparatus is equal to or higher than a threshold.
