Abstract: An electrical connector, such as a bushing insert, includes a housing with an inner bore, opposite ends. One end has an opening providing access to the inner bore. A piston-contact element is movable between first and second axially spaced positions within the inner bore. During fault closure or short circuit conditions, the piston-contact element accelerates connection with a male contact of an electrical connector, such as a cable connector, thereby inhibiting the formation of flashover or electrical arc.

Abstract: A multi-lane link that automatically detects if the lanes in the link have been reordered and corrects the order of the lanes. In one embodiment, the link includes a transmitter and a receiver. The receiver is configured to receive a plurality of lanes and includes a receiver logic circuit configured to receive signals from each of the plurality of lanes. Lane misordering is corrected during a training sequence in which a first training sequence and a second training sequence are bilaterally transmitted between the transmitter and receiver. The receiver monitors the training sequence for symbols that are unique to each lane and if an unexpected symbol is detected in the lane, the receiver logic circuit will correct the order of the lanes. The link further comprises a transmitter logic circuit configured to transmit signals to the lanes. The transmitter logic circuit is configured to reorder the sequence of the signals transmitted to the lanes if the transmitter does not detect a response from the receiver.

Abstract: An adapter configured to automatically detect and compensate for differential signal inversion is herein disclosed. In one embodiment, the adapter is part of a computer network having differential conductor pairs conveying differential signals between network devices. The network devices include adapters coupled to transmit and receive signals via the differential conductor pairs. The adapter preferably includes a lane receiver, a decoder, and a synchronization circuit. The lane receiver is configured to receive a single differential signal and to convert the differential signal into a sequence of code symbols. The decoder decodes the code symbols to produce a sequence of received symbols. The synchronization circuit examines the sequence of received symbols to determine if it is incorrect due to inversion of the differential signal, and if so, it causes the lane receiver to correct for the differential signal inversion.

Abstract: A method and apparatus for performing minimally invasive hip replacement surgery using a T-handle ruler to make measurements inside the surgical site to assist in implanting a prosthetic femoral hip into the intramedullary canal of the natural femur. The ruler has an elongated central body and two measuring ends that are angled with respect to the central body.

Abstract: A mounting bracket for mounting a high voltage surge arrester to a power distribution system including a main body with a first end securable to the high voltage surge arrester and an opposite second end securable to a power distribution system bracket and a plurality of laterally extending weathersheds located between the first and second ends, the second end including a fastening hole that receives a fastener for attaching the second end to the power distribution system bracket, and the main body being formed of polymer plastic blend.

Abstract: An adapter that buffers received symbols and automatically determines and corrects for skew between lanes is disclosed herein. In one embodiment, the adapter is a part of a network that includes a first and second devices coupled together by a communications link having multiple independent serial lanes. The first device initiates communication by repeatedly transmitting a training sequence that includes a start symbol for each lane. An adapter in the second device includes a set of buffers each configured to receive the symbols conveyed by a corresponding serial lane. The buffers are coupled to a reconstruction circuit that removes one “symbol group” at a time from the buffers. A symbol group is made up of one symbol from each buffer. The reconstruction circuit removes symbol groups until a start symbol is detected. If the start symbol is not detected in all buffers, output from the buffers having start symbols is temporarily suspended.

Abstract: A disconnector assembly connects and then isolates and disconnects an arrestor between a power line and ground. The disconnector assembly has a bracket that has a base and a wall. The wall extends substantially perpendicularly from the base and defines a cavity. An isolator assembly is disposed within the cavity. A cap is connected to the wall remote from the base to close the cavity. A blind bore extends into the cap from a surface thereof remote from the cavity. A stud is partially disposed in the bore. An adhesive between the cap and the wall secures the cap to the wall.

Absolute position sensing is used in a feedback loop to control both an alternating current (ac) drive and a direct current (dc) drive to the electromechanical drive. Improved performance and stability results.
