Patent number: 12148412Abstract: Provided is an information processing apparatus including a sensor, an actuator, a vibration control circuit, a transmission circuit, and a reception circuit. The sensor detects vibration of a control target. The actuator provides vibration control of the control target. The vibration control circuit generates a drive signal for the vibration control for the actuator according to an output signal of the sensor, and outputs the generated drive signal to the actuator. The transmission circuit modulates transmission data to produce a transmission signal, and synthesizes the modulated transmission signal to produce the drive signal for the vibration control that is to be outputted to the actuator. The reception circuit extracts a reception signal from the output signal of the sensor, and demodulates the extracted reception signal to produce reception data.Type: GrantFiled: May 25, 2021Date of Patent: November 19, 2024Assignee: SONY GROUP CORPORATIONInventors: Yoshiyuki Kuroda, Kohei Asada, Koya Sato, Masaki Kamata, Tetsunori Itabashi, Shigetoshi Hayashi
