    Abstract: A system for evaluating a degree of brain dysfunction of a subject, such as a decline in cognitive function, calculates a difference in movement functions between both hands in a coordination movement. The system includes a storage device for storing time-series data on a finger movement task of each of both hands of a test subject acquired by a movement sensor; a data processing device for analyzing the time-series data stored in the storage device; and a display device for displaying an analysis result analyzed by the data processing device. The data processing device includes a movement waveform generation unit for generating a movement waveform corresponding to the time-series data stored in the storage device; and a difference-between-hands feature quantity generation unit for generating a difference-between-hands feature quantity which represents a difference in respective finger movement tasks between both hands, based on the respective movement waveforms of both hands.

    Abstract: An electrosurgical instrument includes a shaft assembly, an end effector, an input actuator, a biasing feature, an end of stroke feature, a first clamp closure sensor, a second clamp closure sensor, and a control unit. The end effector includes an energized feature, a first jaw, and a second jaw. The first clamp closure sensor is configured to produce first sensor information relating to movement of the input actuator. The second clamp closure sensor is configured to produce second sensor information relating to deflection of the biasing feature in response to a tissue load force between the first and second jaws. Based on each of the first and second sensor information, the control unit is configured to determine the tissue load force exerted on the end effector, and a position of one of the first and second jaws relative to the other of the first and second jaws.

    Abstract: An ophthalmic device comprises an ultrasonic transducer, an accommodation actuator, and a controller. When the ophthalmic device is mounted in or on an eye of a user, the ultrasonic transducer is positioned to direct ultrasonic signals towards ciliary processes in the eye and the accommodation actuator is positioned to focus light entering the eye. The controller is coupled to the ultrasonic transducer and the accommodation actuator. The controller includes logic that when executed by the controller causes the ophthalmic device to perform operations including emitting the ultrasonic signals from the ultrasonic transducer towards the ciliary processes, receiving reflected ultrasonic signals from the ciliary processes with the ultrasonic transducer, calculating a time of flight between emitting the ultrasonic signals and receiving the reflected ultrasonic signals, and adjusting an optical power of the accommodation actuator based on the time of flight.
