Abstract:
In CE4, a communication terminal transmits data including a latency_off value “1”. After receiving the data, an environment information measuring apparatus transmits data since a latency counter value is “0”. The latency counter value becomes “2” and a latency_off counter value becomes “1”. In CE5, the communication terminal transmits data including a latency_off value “0”. Since each of the latency counter value and the latency_off counter value is not “0”, the environment information measuring apparatus does not receive the data from the communication terminal. The latency counter value becomes “1” and the latency_off counter value becomes “0”. In CE6, since the latency_off counter value is “0”, the environment information measuring apparatus receives the data from the communication terminal.
Abstract:
A movement analysis device includes a sensor information acquisition unit and a swing identification processing unit. The sensor information acquisition unit acquires sensor information that is movement information from a sensor unit which is attached to a target person and which senses the movement of the target person. The swing identification processing unit individually identifies the time of the start of the movement and the time of the completion thereof with reference to a predetermined threshold value in a predetermined timing of the sensor information that is the movement information acquired from the sensor information acquisition unit. The swing identification processing unit identifies a movement within the range of the operation based on the time of the start of the movement and the time of the completion that are identified.
Abstract:
A radio communication apparatus performing radio communication based on either role, a master or a slave, includes: a role change receiver receiving a role change request from a master to a slave when the radio communication apparatus has a role of master and has established connection to another radio communication apparatus operating as a slave; and an identification information transmitter transmitting identification information to the other radio communication apparatus on a given channel at shorter time intervals when the role change receiver receives the change request than a given comparison criterion for when the role change receiver does not receive the change request.
Abstract:
When executing a predetermined application in which radio communication with a slave device is necessary, a master device scans an advertisement from the slave device by using previously-set one channel among three channels for advertising. When transmitting the advertisement to the master device executing the predetermined application, the slave device transmits the advertisement by using previously-set one channel among three channels for advertising.
Abstract:
When the first connection is established with a slave, the master determines one channel selected from three advertising channels, as a channel used for establishment of the subsequent connection with the slave, and notifies the slave of the one channel. When the first connection is established with the master, the slave transmits an advertise in the three advertising channels. Further, when the second or subsequent connection is established with the master, the slave transmits the advertise in the one channel notified of from the master.
Abstract:
A communication apparatus includes a communication unit and a controller. The controller determines, according to a first reference of received signal strength in one communication apparatus which is either an external communication apparatus or the communication apparatus, a transmitted signal strength for a transmission radio wave from the other communication apparatus as a first reference of transmitted signal strength. The controller determines a second reference of transmitted signal strength between the first reference of transmitted signal strength and a maximum strength of transmitted signal strength from the other communication apparatus. When a predetermined condition is satisfied, the controller obtains a received signal strength of the one communication apparatus for the transmission radio wave in the second reference of transmitted signal strength and determines a transmitted signal strength of a transmission radio wave from the other communication apparatus according to the received signal strength.
Abstract:
A peripheral transmits an advertisement including an order of connection priority of when a central is connected to the own apparatus. The central receives the advertisement. The central acquires the order of connection priority included in the received advertisement. The central controls transmission of a connection request signal to the peripheral based on the acquired order of connection priority. In response to the transmitted advertisement, the peripheral receives a connection request signal transmitted from the central. According to the connection request signal, the peripheral establishes connection with the central.
Abstract:
A radio communication apparatus performing radio communication based on either role, a master or a slave, includes a role change receiver receiving a role change request from a slave to a master when the radio communication apparatus has a role of slave and has established connection to another radio communication apparatus operating as a master, and a receiver awaiting identification information transmitted by the other radio communication apparatus by receiving multiple channels including a given channel in a given pattern when the role change receiver receives the change request. The receiver receives the multiple channels in the given pattern such that the time or number of times of awaiting the identification information on the given channel is longer or higher than a given comparison criterion for when the role change receiver does not receive the change request
Abstract:
An objective of the present disclosure is to provide a wireless communication device that is capable of efficiently searching another wireless communication device that is capable of providing a required service. A master device, when the master device receives an advertisement from a slave device, transmits, to the slave device, a scan request that includes information on a requested service that the master device requires. The slave device, which has received the scan request, decides whether or not the slave device itself is capable of providing the requested services, and transmits, to the master device, a scan response that includes a result of the decision. When the decision result included in the scan response indicates that the slave device is capable of providing the requested service, the master device establishes a connection to the slave device.

In CE4, a communication terminal transmits data including a latency_off value “1”. After receiving the data, an environment information measuring apparatus transmits data since a latency counter value is “0”. The latency counter value becomes “2” and a latency_off counter value becomes “1”. In CE5, the communication terminal transmits data including a latency_off value “0”. Since each of the latency counter value and the latency_off counter value is not “0”, the environment information measuring apparatus does not receive the data from the communication terminal. The latency counter value becomes “1” and the latency_off counter value becomes “0”. In CE6, since the latency_off counter value is “0”, the environment information measuring apparatus receives the data from the communication terminal.
