A wireless communication apparatus includes a wireless communicator configured to perform wireless communication with another wireless communication apparatus, and a processor. The processor controls the wireless communicator to transmit to the other wireless communication apparatus prescribed information while incrementally changing transmission power by a prescribed degree until a change occurs in a signal reception state of a connection request from the other wireless communication apparatus, and starts transmission of the prescribed information to the other wireless communication apparatus during a next communication onwards at a transmission power based on a transmission power occurring when the change occurs in the signal reception state of the connection request.

A communication system () comprises a central () and a peripheral (). The central () receives location information and time information from NTP servers () and a location server (). The central () creates first offset information of the time measured by its own device and the time information received from the NTP servers (). The central () acquires from map information a time difference corresponding to a location presented by the location information received from the location server (). The central () creates first updated time information based on the time measured by its own device, first offset information, and time difference corresponding to the location presented by the location information received from location server () and transmits the first updated time information to the peripheral (). The peripheral () changes the time displayed by its own device based on the received first updated time information.

A wireless communication apparatus includes (i) a wireless communicator capable of broadcasting an extended advertising packet having a large transmittable capacity and a compatible advertising packet having a transmittable capacity smaller than the extended advertising packet, and (ii) a processor. The wireless communicator periodically broadcasts the extended advertising packet based on a command from the processor. The processor sets offset information for acquiring of a time at which the extended advertising packet is receivable in an offset notification packet that is the compatible advertising packet, and broadcasts the offset notification packet via the wireless communicator. The offset information is set based on a transmission timing of the offset notification packet and a transmission timing of the extended advertising packet.

An electronic terminal capable of using a function of payment includes a wearing detector, a communicator, and a processor. The wearing detector detects whether the electronic terminal is worn by a user. The communicator communicates with a wireless communication apparatus via near field communication. The processor changes, based on information that is obtained by the wearing detector and the communicator, whether to enable or disable use of the function of payment.

A wireless communication device includes a wireless communicator and a processor. The wireless communicator wirelessly communicates with another wireless communication device. The processor controls the wireless communicator to broadcast connection information when reconnection to the other wireless communication device or wireless communication after reconnection with the other wireless communication device fails after termination of a connection with the other wireless communication device. The connection information is information related to the connection.

According to an aspect of the present invention, a device includes a transmitter and receiver that transmits and receives communication packets to and from other device, and a processor. The processor receives a packet containing first information indicating a structure type of data from the other device via the transmitter and receiver and communicates data corresponding to the first information with the other device via the transmitter and receiver.

Communication device, communication method, and storage medium

According to an aspect of the present invention, a device capable of wireless communication includes a communicator configured to transmit and receive communication packets to and from other device, a memory configured to store one or more kinds of setting information, and a processor configured to determine whether or not at least one of the one or more kinds of setting information has been changed after the last communication with the other device, generate discrimination information indicating whether or not each of the one or more kinds of setting information has been changed, and control communication with the other device based on the discrimination information.

According to an aspect of the present invention, a device capable of wireless communication includes a counter for counting current time, and a processor for setting a communication mode of the device to one of a notification mode in which the device sends a first notification signal for informing of its existence and a detection mode in which the device detects a second notification signal sent from other device. In the case that the processor changes the communication mode of the device from the notification mode to the detection mode and the second notification signal received in the detection mode includes first time information, the processor corrects time of the counter based on the first time information.

An optical biological information detecting apparatus includes a light emitting unit which emits observation light of a specific wavelength band to optically observe a desired portion of a tissue of a skin of a human body, and an annular light guide unit which guides the observation light to a desired area of a surface of the skin corresponding to the desired portion of the tissue of the skin, and which annularly irradiates the observation light onto the desired area of the surface of the skin. The apparatus further includes a light receiving unit which is disposed at a position surrounded by the annular light guide unit, and which receives scattered light scattered by the desired portion of the tissue of the skin after the observation light is annularly irradiated onto the desired area of the surface of the skin by the annular light guide unit.

Optical biological information detecting apparatus and optical biological information detecting method

The wearable heartbeat measuring device is accomplished by wearing a wrist-watch-like heart monitor device on the wrist. The heart monitor is worn on the top of the wrist with a strap around the wrist. The strap has an inflexible extending portion that extends from the heart monitor at a predetermined angle and a predetermined width with respect to the wrist so that a predetermined space is maintained between the top portion of the wrist and the strap for promoting the transfer efficiency of the pulsation force that is initially experienced at a part of the strap at the bottom of the wrist. The strap also has a flexible portion. A predetermined angle and a predetermined width of the extended portion also facilitate the flexible portion to form a flat area where the wrist contacts the strap. In the prefer embodiments, the width of the strap exceeds the width of the wrist when it is worn.
