A surgical instrument comprising an end effector is disclosed. The end effector comprises a surgical dissector. The surgical dissector can apply mechanical and/or electrosurgical energy to treated tissue.

A surgical instrument comprising a jaw assembly is disclosed. The surgical instrument further comprises a motor-driven drive system configured to open the jaw assembly. The surgical instrument also comprises a control system configured to control the drive system and, also, control a power supply system configured to supply electrical power to electrodes defined in the outer surface, or outer surfaces, of the jaw assembly. In use, the surgical instrument can be used to apply mechanical energy and electrical energy to the tissue of a patient at the same time, or at different times. In certain embodiments, the user controls when the mechanical and electrical energies are applied. In some embodiments, the control system controls when the mechanical and electrical energies are applied.

A drive assembly for a work vehicle has a drive housing including at least one housing element forming a reaction member, a drive shaft rotatable about a drive axis, and a planetary gear set coupled to the drive shaft and configured to selectively rotate an output element. The drive assembly also includes at least one clutch arrangement having at least one clutch ring configured to selectively interact with the planetary gear set to effect a rotation speed of the output element. At least one actuator is configured to axially drive the clutch ring along the drive axis. A retention mechanism is configured to retain the clutch ring at an axial position along the drive axis. The retention mechanism includes a detent ball, a detent groove and a resilient member configured to urge the detent ball into the detent groove to retain the clutch ring at the axial position.

A soft actuator, its working method and robot are provided. The soft actuator includes a power input shaft, and multiple electromagnetic clutches are coaxially installed in series on the power input shaft. A bending elastic part is arranged between the thrust plate of each electromagnetic clutch and the gear frame of the electromagnetic clutch. The bending elastic part is installed on the sleeve of the gear frame and in contact with the baffle of the gear frame. The bending elastic part is connected with the clutch output gear of the electromagnetic clutch through the gear frame. The gear frame is fixedly connected with the clutch output gear and rotates coaxially.

A surgical instrument system comprising a handle, a shaft, and a disposable power module is disclosed. The handle comprises a motor, a control switch, and a motor-control processor which is in communication with the control switch. In various instances, the disposable power module comprises a disposable battery and a display unit configured to indicate at least one function of the surgical instrument system.

A surgical clip applier is disclosed which is configured to automatically feed a clip from a clip cartridge once the surgical clip applier is positioned in the patient.

The present invention relates to a transportation system for transporting products in a transportation direction. The transportation system comprises a conveyor unit for transporting the products in the transportation direction from a first end of the conveyor unit towards a second end of the conveyor unit, and a drive unit for driving the conveyor unit. The drive unit comprises a drive means and a first magnetic clutch component for transmitting torque to the conveyor unit. The conveyor unit comprises a second magnetic clutch component for receiving torque from the drive unit. The transportation system further comprises supporting means which includes first and second supporting elements with the first supporting elements arranged at the drive unit and the second support elements arranged at the conveyor unit, for supporting the conveyor unit such that at least the first magnetic clutch component and the second magnetic clutch component are aligned to each other, and for supporting torque transmitted from the drive unit to the conveyor unit. The present invention further relates to a drive unit as well as a conveyor unit, both adapted for use in a transportation system.

A rotational coupling device drives an output synchronous with either of two inputs. The device includes a hub disposed about an axis and an output member supported on the hub for rotation about the axis. First and second input members disposed about the hub are configured to rotate in first and second rotational directions and at first and second speeds, respectively, with at least one of the directions and speeds differing. A clutch member is disposed axially between the input members and coupled to the output member. An electromagnet is on an opposite side of the second input member relative to the clutch member. When the electromagnet is deenergized, the clutch member engages the first input member and the output member rotates with the first input member. When the electromagnet is energized, the clutch member engages the second input member and the output member rotates with the second input member.

The invention relates to an aircraft flight control column device (1) comprising: a casing (2) for attaching to an aircraft structure; an output shaft (3) for connecting to a flight control column (56), the output shaft (3) being mounted such that it rotates in relation to the casing (2); a primary group (4) comprising a first torque-generating body (7, 8) for applying a first torque to the output shaft (3); a secondary group (5) comprising a second torque-generating body (7, 8) for applying a second torque to the output shaft (3); and a clutch for selectively connecting the primary group (4) and the secondary group (5) to the output shaft (3).
