Abstract:
Provided is a radio formed to be capable of performing wireless communication with sensors, and configured to be connected, through one communication port via wired communication, to a slave control apparatus configured to be communicably connected to a master control apparatus with a predetermined communication method. The radio generates one communication packet formed with the predetermined communication method and transmitted from the radio to the slave control apparatus, such that pieces of measured data measured by the sensors are included in the one communication packet in accordance with a predetermined order in which the slave control apparatus or the master control apparatus can determine which sensor measured which piece of the measured data of the sensors, and the radio transmits the generated one communication packet to the slave control apparatus via wired communication.
Abstract:
In an apparatus for measuring biological information using a radio wave, a technique for acquiring an index related to a setting position of the apparatus with respect to a measurement site is provided. A biological information measurement apparatus (1) according to an aspect of the present disclosure includes a transmitter (3) configured to transmit a radio wave toward a measurement. site of a living body; a receiver (4) configured to receive a reflected wave of the radio wave reflected by the measurement site and output a waveform signal of the reflected wave; a feature extraction unit (121) configured to extract information indicative of a feature of a waveform from the waveform signal; a determination unit (122) configured to determine whether a setting position of the biological information measurement apparatus with respect to the measurement site satisfies a condition corresponding to a preset reference position based on the extracted information indicative of the feature of the waveform; and an output unit (5) configured to output information indicative of a determination result determined by the determination unit.

Target driving directivity information corresponding to a target driving pattern acquired by an acquisition unit is selected from among pieces of driving directivity information relating to a directivity applied to the directional antenna in a state in which driving of the one or more driving devices is controlled by the control apparatus in accordance with the plurality of driving patterns, the selected target driving directivity information is applied to the directional antenna of the first radio, and wireless communication between the first radio and the second radio is executed.
Abstract:
A wireless communication control system includes a first radio having a directional antenna, a second radio, a directivity control unit controlling the directivity of the directional antenna, and a directivity information storage unit storing directivity information relating to a directivity, the directivity information being applied to the directional antenna in relation to wireless communication between the first and second radios in accordance with a plurality of change patterns indicating a temporal change in a received signal intensity. The directivity control unit acquires a temporal change in a received signal intensity during wireless communication between the first and second radios, selects, from among pieces of the directivity information stored in the directivity information storage unit, directivity information corresponding to the change pattern corresponding to the temporal change in the received signal intensity, applies the selected directivity information, and executes wireless communication between the first and second radios.
Abstract:
In a wireless control terminal configured to control a control target connected to a control apparatus by working in cooperation with a wireless assistant terminal capable of transmitting a predetermined control instruction for controlling the control target to the control apparatus by using a predetermined control wireless scheme with supply of power from a battery included in the wireless assistant terminal, a wireless control terminal-side battery is provided within the wireless control terminal so as to supply driving power required for control regarding emergency stop of the control target performed with a predetermined wireless scheme of the wireless control terminal. At least remaining storage power information regarding a remaining amount of storage power in the wireless control terminal-side battery is output to a notification apparatus provided in the wireless control terminal or the wireless assistant terminal.
Abstract:
A parent node in a wireless communication system includes a generation unit configured to generate a send request including response instruction data specifying child nodes required to respond, and a response timing for each of the child nodes required to respond. A child node in the wireless communication system according to the invention includes a receiving unit configured to receive the send request; a response determination unit configured to determine from the response instruction data whether or not the child node itself is required to respond to the send request; and a response transmission unit configured to transmit a response at a response timing based on the response instruction data, when the child node is required to respond to the send request.
