Abstract: A standing-up assistance apparatus includes a first sensor that measures a muscle potential of a lower leg of a user, a second sensor that measures a knee angle of the user, a processor that determines whether starting to assist the user in a standing-up motion from a seated state is possible, based on, at least, the measured muscle potential and the measured knee angle, and outputs an instruction signal if the processor determines that starting to assist the user in the standing-up motion is possible, and an assistance mechanism. The assistance mechanism starts assisting the user in the standing-up motion when the assistance mechanism receives the instruction signal from the processor.

Abstract: An input apparatus for controlling an information terminal includes a gesture detecting unit that detects a rotational movement of a wrist of a user about a lower arm of the user and an output unit that outputs a control command for controlling a device to be controlled to the device to be controlled on the basis of a rotational direction of the detected rotational movement. If the gesture detecting unit detects a first rotational movement in a first rotational direction and thereafter detects a second rotational movement in a second rotational direction that is opposite to the first rotational direction, the output unit outputs a second control command corresponding to the second rotational direction without outputting a first control command corresponding to the first rotational direction.

Abstract: A standing motion assist device includes a support mechanism attached to a leg of a user to assist the user with motion, a sensor including first and/or second sensors that measure and output posture information and myoelectric potentials of the user, respectively, the sensor outputting measurement data including first measurement data measured after a sitting motion of the user sitting in a chair starts and second measurement data measured after the sitting motion ends, a memory that stores the measurement data, and a processor that controls the support mechanism. The processor detects the sitting motion and identifies the chair type based on the first measurement data, detects the start of a motion of the user standing from the chair based on the second measurement data, and outputs assist information corresponding to the identified chair type and used by the support mechanism to assist the user with standing.

Abstract: In an imaging device, a difference calculation unit calculates a differential signal between charge signals that have been accumulated and are held by first and charge holding units with different timings. A multiple sampling unit performs multiple sampling processing on the differential signal, and an analog digital conversion unit converts a signal that has undergone multiple sampling processing to a digital signal. That is, multiple sampling processing is performed on a differential signal with a higher sparsity than that of an image signal.
