A rotary operating device includes an operation part that is rotatable according to an operation by an operator, a rotation angle sensor that detects a rotation angle of the operation part, a torque applier that applies application torque to the operation part along a rotation direction of the operation part, a frictional force applier that applies a frictional force to the operation part, and a processor programmed to change the application torque and the frictional force according to the rotation angle.

The operating device for a vehicle component, in particular a human machine interface (HMI) for vehicles, is provided with a housing, comprising a front wall having a front face in particular with a display surface and a rear face facing away from the front face, and an operating element unit which is positioned and/or can be positioned on and/or in front of the front wall of the housing for manually triggering operating functions and/or for manually adjusting parameters of operating functions for a vehicle component. The operating element unit comprises at least one operating element, a display element and/or a display device, an evaluating and control unit assigned to the at least one operating element and to the display element or the display device, and an energy supply unit. In order to supply electric energy to the energy supply unit of the operating element unit, at least one first coil is arranged so as to face the rear face of the front wall, wherein at least one second coil, which is inductively coupled to the at least one first coil and is connected to the energy supply unit, is arranged in and/or on the operating element unit.

A wearable hearing device operatively coupled to an information handling system comprising a housing for a speaker and a microphone, a magnetic slider switch moveable with respect to the housing between a closed position and an open position in response to a user's external force, a rolling magnet rotating within the magnetic slider switch during movement between the open and closed positions, a bar magnet fixed within the housing having a first pole attracting the rolling magnet in the closed position and a second pole attracting the rolling magnet in the open position to reduce the external force required to move the magnetic slider switch, a hall effect sensor to sense a change in distance to the rolling magnet during movement between the open and closed positions, and to associate the change in distance with a command instruction, and a microcontroller to execute or transmit the command instruction.

A target magnet mechanism for a proximity switch. The target magnet mechanism includes a plurality of magnets disposed in an alternating magnetic pole configuration forming a narrowed, polarity reversing magnetic field. A center magnet has a magnetic polarity opposite the magnetic polarity of a sensing magnet of the proximity switch. A flanking magnet includes a magnetic polarity opposite the magnetic polarity of the center magnet and the same as the sensing magnet. So configured, the plurality of magnets trigger the proximity switch to an activated state by pulling on a magnetic field of the proximity switch via the opposed polarity of the center magnet and the sensing magnet. In addition, the plurality of magnets release the proximity switch back to an unactivated state by pushing on the magnetic field of the proximity switch via the same polarity of the flanking magnet and the sensing magnet.

An interactive control unit is disclosed. The interactive control unit includes an interactive touchscreen display, an interface configured to couple the control unit to a surgical hub, a processor, and a memory coupled to the processor. The memory stores instructions executable by the processor to receive input commands from the interactive touchscreen display located inside a sterile field and transmit the input commands to the surgical hub to control devices coupled to the surgical hub located outside the sterile field.

A surgical instrument is disclosed. The surgical instrument includes a drive system and a control circuit. The drive system includes an electric motor. The control circuit includes an acoustic sensor, and is configured to utilize a parameter of the drive system measured by the acoustic sensor to control a speed of the electric motor.

A surgical instrument is disclosed. The surgical instrument includes a body, a shaft and a control circuit. The control circuit includes at least one sensing device and is to determine a presence of another surgical instrument proximate to the surgical instrument within an environment of a surgical procedure.

A surgical instrument is disclosed comprising a housing and a control circuit mounted to and/or embedded in the housing.

A surgical instrument is disclosed comprising an actuator and circuitry mounted on and/or embedded in the actuator.

A surgical instrument is disclosed comprising a control system and a strain gage circuit. The operation of the control system is modifiable by an input from the strain gage circuit.
