A surgical instrument including a handle assembly, a first endoscopic portion, a motor, and a first end effector is disclosed. The first endoscopic portion is selectively connectable to a distal portion of the handle assembly and defines a longitudinal axis. The first endoscopic portion includes a housing adjacent its proximal portion and includes an actuation member. The motor is disposed in mechanical cooperation with the housing of the first endoscopic portion and is operatively connected to the actuation member for moving the actuation member substantially along the longitudinal axis. The first end effector is selectively connectable to a distal portion of the first endoscopic portion and is configured to perform a first stapling function.

An interchangeable transducer for use with an ultrasound medical system having a keyless adaptor and capable of operating in a wet environment. The interchangeable transducer has an adaptor for engaging a medical system, an ultrasound transducer and additional electronics to provide a self-contained insert for easy replacement and usage in a variety of medical applications. A slip ring spacer is also disclosed, the slip ring spacer for use with a pancake slip ring having a base and flange configuration to form one or more channels around each contact ring of the pancake slip ring. The channels provide fluid isolation around each connector to help reduce electronic cross talk and contact corrosion between the connector pads of the slip ring while the slip ring is immersed in a wet environment.

An illuminated vehicle wheel assembly having arrays of illuminated electrical elements such as light emitting diodes, which are powered by the vehicle power systems by way of a slip ring assembly associated with the bearing or bearing seal of the vehicle wheel.

A power plug with a freely rotatable delivery point is disclosed, wherein a relative orientation between a delivery point element (e.g. an electric wire) and insertion terminals of the plug can change freely on a plane. A plug seat includes an armature which displaces axially. An open end of the seat is loosely connected with a turntable which is coaxial with the armature. The turntable is assembled with the insertion terminals which loosely contact with the armature by relative rotation. Between the seat and the armature, an elastic arch element is axially provided and parts of the insertion terminals relative to the armature are indirectly provided with plate-shaped conducting probes with an elastic shear. By the elastic arch element and the conducting probes, a mechanical vibration wave occurring during rotation of the turntable is absorbed, such that the armature can actually contact with the terminals to avoid jump sparks.

A process of fabricating a slip ring component, a slip ring component, and a slip ring assembly are disclosed. The process includes forming a first shot, forming a second shot, and immersion bathing the first shot and the second shot. The immersion bathing applies an electrically conductive plating to exposed surfaces of the second shot.

The invention relates to a connection device associated with an arm of an articulated three-dimensional measuring appliance, the device comprising a moving assembly and a fixed assembly, together with connection means for providing an electrical link between said two assemblies. In accordance with the invention, the moving assembly comprises first and second adjacent components on a common axis, the first component being constrained to rotate with the jointed end of the arm and being connected to the second component by a coupling system having successive dogs so that said second component is entrained in rotation only after said first component has turned through significantly more than one revolution in the same direction, and the connection means comprise facing contact members carried respectively by the fixed assembly and by the second component, arranged to provide a continuous electrical link in normal operation and a link that is restricted to a short angular range of rotation once the second component is entrained in rotation by the first component.

A power pick-up for an Inductively Coupled Power Transfer (ICPT) system is provided having a resonant pick up circuit. The natural frequency of the pick-up circuit may be varied by controlling the conductance or capacitance of a variable reactive in the resonant circuit. The load being supplied by the pick-up circuit is sensed, and the effective capacitance or inductance of the variable reactive component is controlled to vary the natural resonant frequency of the pick-up circuit to thereby control the power flow into the pick-up to satisfy the power required by the load.

A magnetic attachment mechanism and method is described. The magnetic attachment mechanism can be used to releasably attach at least two objects together in a preferred configuration without fasteners and without external intervention. The magnetic attachment mechanism can be used to releasably attach an accessory device to an electronic device. The accessory device can be used to augment the functionality of usefulness of the electronic device.

An entirely wearable electrical connector for power / data connectivity. The principal element of a modular network is the wearable electrical connector, which is integrated into a personal area network with USB compatibility. An embodiment comprises a non-conductive elastomeric environmental seal.

The present invention is directed to a weatherproof electrical outlet box assembly for shielding and protecting electrical components from moisture comprising a faceplate for attaching to an outlet box, the faceplate being substantially planar, and perimetrically bounded by a substantially rectangular side edge, the faceplate having at least one aperture for receiving an electrical component and; the faceplate including a first hinge socket and a second hinge socket extending respectively from the side edge in substantially orthogonal orientation. The weatherproof electrical outlet box assembly further including a cover having a front wall, an opposed open end and a substantially rectangular perimetrical side wall therebetween defining a cover interior, the side wall having a rim bounding the open end, the cover including at least one access port through the side wall adjacent the open end for providing separate passageways into the interior of the cover; the cover including a first hinge pin and a second hinge pin extending respectively from the side wall adjacent the open end in substantially orthogonal orientation; and the cover being pivotally affixed to the faceplate by operative engagement of the hinge socket with the hinge pin of corresponding orientation and movable between an open and a closed position and wherein the hinge pin and the hinge socket that are not in operative engagement are not aligned.

A non-contacting rotary interface has a first core with a first pair of balanced transmission lines coupled to the first core and a second core moveable in relation to the first core with a second pair of balanced transmission lines coupled to the second core and configured to receive signals from the first pair of balanced transmission lines. The first pair of balanced transmission lines has a first transmit wire coupled to a first transceiver at a first end of the first transmit wire, a second transceiver coupled to the first transmit wire at a second end of the first transmit wire, a second transmit wire coupled to a third transceiver at a first end of the second transmit wire, and a fourth transceiver coupled to the second transmit wire at a second end of the second transmit wire. The balanced transmission lines may be electrical traces on a circuit board.

An electronic device includes a hollow pivot member interconnecting a main housing and a connector housing of an electrical connector such that the pivot member is rotatable relative to the electrical connector about a first axis and relative to main housing about a second axis perpendicular to the first axis, and a wire unit extending from the connector housing through the pivot member and into the main housing and interconnecting electrically a conductive terminal unit of the electrical connector and a circuit unit in the main housing. Relative rotation between the pivot member and the connector housing about the first axis is prevented by a first positioning unit. Relative rotation between the pivot member and the main housing about the second axis is prevented by a second positioning unit.
