The present disclosure provides a surgical instrument including an end effector, a drive member movable to effectuate a motion in said end effector, a motor operable to move the drive member to effectuate the motion in the end effector and a bailout assembly operable to perform a mechanical bailout of the surgical instrument in response to a bailout error. The bailout assembly includes a bailout door, a bailout handle accessible through the bailout door. The bailout handle is operable to move the drive member to effectuate a bailout motion in the end effector. A controller includes a memory and a processor coupled to the memory. The processor is configured to detect the bailout error. The processor is programed to stop the motor in response to the detection of the bailout error.

A rotary connector device includes a fixed body, a rotation body, and a connector. The rotation body is rotatable about a rotation axis with respect to the fixed body. The rotation body is assembled to the fixed body in a manner to form a first space between the rotation body and the fixed body. The connector includes a second space. The connector includes a first opening and a second opening. One end of a first cable is connected to a first electrode provided in the second space. One end of a second cable is connected to a second electrode provided in the second space. The first cable passes through the first opening. The other end of the first cable is connected to the rotation body. The second cable passes through the second opening. The other end of the second cable is connected to the rotation body.

A steering roll connector configured to operatively engage a steering column. The steering roll connector may comprise a roll stator and a roll rotor telescoped in and rotatable with the roll stator. The roll rotor may have a wall and a surface, and the wall may define an opening for receiving the steering column. A slide may be supported by and movable on the surface from an unengaged position to an engaged position where the slide is positioned to engage and prevent the relative rotation between the roll rotor and roll stator. A spring may operatively engage the slide to causes it to be in the engaged position. When the steering column is received in the opening, a lever arm may operatively engage and pull the slide to the unengaged position.

Aspects of the technology relate to rotational electromechanical systems, in which data and or power are supplied to components while one part of the system is rotating relative to another part of the system. Repeated rotation may create strain on or otherwise cause the cables to intermittently or permanently fail. A helical cable management system is provided that enables full rotation to the extent permitted. One or more cables are wound in a helical shape around the axis of rotation, which distributes the deformation of the cable along the helical length. Rotation in one direction causes the helix diameter to increase, while rotation in the other direction causes the helix diameter to decrease. A structure is used to maintain the distance between helical turns, while permitting the increase and decrease of the helix diameter. This reduces the overall strain on the cables, which can significantly extend their useful lifetime.

An instrument drive unit includes a housing configured to be coupled to a surgical robotic arm, a motor assembly, and a flex spool assembly. The motor assembly is rotatably disposed within the housing. The flex spool assembly includes a first printed circuit board mounted to the housing, a second printed circuit board configured to be non-rotatably coupled to and electrically connected to the motor assembly, and a first flex circuit. The first flex circuit has a first end portion connected to the first printed circuit board, a second end portion connected to the second printed circuit board, and an intermediate portion coiled about the second printed circuit board such that rotation of the motor assembly relative to the housing effects movement of the second end portion of the first flex circuit along an annular path.

An electronic apparatus includes a movable cylinder, a support cylinder configured to support the movable cylinder rotatably around a panning rotation axis, a flexible wire connecting to a panning control circuit board in the support cylinder, and a storage area communicating with the movable cylinder and the support cylinder and containing the flexible wire. The flexile wire includes a first fixed part on the movable cylinder and a second fixed part on the support cylinder. In the storage area, the first fixed part is fixed to a first fixing part of the movable cylinder. In the storage area, the second fixed part is fixed to a second fixing part of the support cylinder.

A waterproof circular connector includes a male head, a female seat and a ring member. The male head provides a first circular body, a third circular body, a first electrode group and a third electrode group. The female seat provides a first base, a second circular body, a fourth circular body, a second base, a second electrode group and a fourth electrode group. The male header is combined with the female seat. The third circular body is inserted between the second and fourth circular bodies, so that the third electrode group is electrically connected to the second electrode group and the first electrode group is electrically connected to the fourth electrode group. The first, second, third and fourth electrode groups are combined with the third circular body by the ring member to prevent water and dust entering from the outside and realize non-directional electrical connections.

An electrically conductive, single-piece flat part (100) for a plug with first and second contact pins (112, 114) are arranged in two parallel rows, and with a connector region for a cable. The part has a connecting element (102). Conductors (108, 110) which open into the first and second contact pins (112, 114) extend from the first and from the second side of the connecting element, the conductors (108, 110) which lie on the opposite sides of the connecting element (102) being connected to the connecting element (102) in a manner which is offset with respect to one another in such a way that the imaginary straight extension of a conductor (108, 110) runs on the one side of the connecting element (102) next to one or between two conductors (108, 110) on the opposite side of the connecting element (102). The first contact pins (112) are connected via an offset region (132) to the first conductors (108) which extend from the first side of the connecting element (102), which offset region (132) compensates for the offset of the first and second conductors (108, 110) on the connecting element (102).

An apparatus for wearing a power cord includes an elongate power cord having a length that extends from a first end having a power connector to a second end having a device connector. The apparatus also includes an elastic component and a housing for holding the power connector and the device connector therein. The apparatus has a wearing configuration and a charging configuration. In the wearing configuration, the device connector and the power connector are disposed in the housing and the apparatus is secured to the user. In the charging configuration, the device connector extends out of the housing and connects to a portable electronic device, and the power connector extends out of the housing and connects to a power supply. In another embodiment, the power cord has a power bank on a first end of the cord rather than a power connector. The power bank is stored inside the housing.
