A tactile presentation device includes a panel including a region touchable by a user, vibrators disposed outside the touchable region, and a driving controller to supply driving signals to the vibrators. At least a part of the entire outer end of the panel is an absorber end region. Each point closest to one of the vibrators on the entire outer end of the panel is included in the absorber end region. The driving controller supplies driving signals to the vibrators to generate a standing wave on the touchable region. Each of the driving signals is a synthetic wave of a carrier and a modulating wave at a frequency lower than a frequency of the carrier. The driving controller is configured to control location of a node of the standing wave in the touchable region with phase differences among carriers of the driving signals for the vibrators.

Tactile presentation device

An ultrasonic sensor device includes a plurality of pixels each including an ultrasonic transducer, and a control circuit configured to control the plurality of pixels. Each of the plurality of pixels is configured to hold a signal received by the ultrasonic transducer therein and send the signal to the control circuit as a response signal. The control circuit is configured to acquire an excitation response signal, which is a response signal sent from a pixel after the ultrasonic transducer therein is excited, acquire a non-excitation response signal, which is a response signal sent from a pixel when the ultrasonic transducer therein is not excited, and correct the excitation response signal based on the non-excitation response signal.

Ultrasonic sensor device and method of controlling the same

A tactile presentation device includes a panel, a first supporting member that secures and supports a first end of the panel, a vibration generator disposed at a position facing the first supporting member across a target area to be touched by a user on the panel, and a driving control device that provides the vibration generator with a driving signal. The driving control device makes only the vibration generator vibrate to form a standing wave in an area including the target area between the vibration generator and the first end. A first vibration reflection rate at the first end for a carrier wave from the vibration generator is negative. A second vibration reflection rate for the carrier wave from the vibration generator at a second end of the panel that is opposing to the first end across the vibration generator is greater than the first vibration reflection rate.

An installation system has a laser range finder set at a reference position to measure a distance to a target, an installation cart which performs operation for laying a magnetic marker in a road, and an arithmetic unit which identifies a position relation of a laying position where the magnetic marker is laid with respect to the reference position. When operation for laying the magnetic marker in a road is performed, by taking the installation cart during performing the operation of laying the magnetic marker in the road as a target, based on a distance to the installation cart measured by the laser range finder, the position relation of the laying position with respect to the reference position is identified by the arithmetic unit.
