WIRELESS COMMUNICATION APPARATUS AND CONTROL METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18267316 titled 'WIRELESS COMMUNICATION APPARATUS AND CONTROL METHOD
Simplified Explanation
The communication device described in the patent application includes an antenna with a rod-shaped element, a support portion, an actuator, a floating body, a sensor, and a control device. The antenna can be rotated about a rotation axis orthogonal to the element's extending direction, with the actuator responsible for this rotation. The floating body supports the support portion and floats on water, while the sensor measures a physical quantity related to the support portion's inclination. The control device includes a measurement value acquisition unit and a rotation control unit, with the former acquiring the sensor's measurement value and the latter driving the actuator based on this value to align the antenna's direction with the smallest change in inclination.

Original Abstract Submitted
A communication device includes an antenna, a support portion, an actuator, a floating body, a sensor, and a control device. The antenna has a rod-shaped element. The instruction unit supports the antenna rotatably about a rotation axis orthogonal to an extending direction of the element. The actuator rotates the antenna about the rotation axis. The floating body supports the support portion and floats on water. The sensor measures a physical quantity related to inclination of the support portion. The control device includes a measurement value acquisition unit and a rotation control unit. The measurement value acquisition unit acquires a measurement value of the sensor. The rotation control unit drives the actuator on the basis of the measurement value to match a direction in which a change in the inclination is smallest with an extending direction of the antenna.
