A power line communications (PLC) network zoning device may include a housing, a power cord extending from the housing, and a plurality of power outlets mounted on the housing, the plurality of power outlets coupled to internal power lines within the housing. An isolation device disposed within the housing may transmit electrical power from the power cord to the internal power lines while isolating PLC communications traffic on the internal power lines from PLC communications traffic on the power cord. A bypass device internal to the housing may selectively transfer PLC communications traffic between the internal power lines and the power cord bypassing the isolation device.

A network device may include a processor executing higher layer processes including layers of a protocol stack higher than a media access layer, a first physical interface (PHY) coupled to a first communications medium, a second PHY coupled to a second communications medium, and a media access controller (MAC) to execute the media access layer of the protocol stack, the MAC coupled to the higher layer processes, the first PHY, and the second PHY. Media selection logic may select one of the first PHY and the second PHY for communication with a target device designated by a target MAC address provided by the higher layer processes.

A patellofemoral brace consisting of a sleeve adapted to be worn by a user in the knee area and having a patella interior opening is provided with a glide which is adjustably carried by the sleeve and which includes a patella engaging brace pad which may be silicon filled and which is generally U-shaped having one longer leg and one shorter leg. The brace is used to influence proper positioning of the patella by the generation of a force applied to the superolateral aspect of the patella to correct misalignment of the patella.

A method and system for adjusting the bandwidth allocated for isochronous data traffic on an interconnected data bus is disclosed. The present system uses an isochronous resource manager (IRM) to sense a bandwidth change request from a talker. The IRM instigates a bandwidth adjustment associated with the bandwidth change request to one or more bus bridge portals.

A method and system for using a new bus identifier in an interconnect, and the interconnect including a plurality of nodes and at least one bus bridge. A configuration change is determined on the first bus connected to the plurality of nodes. Each node has a corresponding bus identifier. A new bus identifier is assigned for each node having a changed state if a configuration change is determined on the first bus.

A method and system for ordering an interconnect topology to form a ring structure, the topology comprising a number of nodes, are described. In one embodiment, a self identifier for each of the nodes is determined. Further, the self identifier is mapped to a ring identifier for each node. In addition, each node computes the ring identifier of one of its port-connected nodes as its topologically adjacent neighbor identifier.

An electromagnetic starter with an overload relay having magnetic flux shielding is disclosed for use in industrial contactor applications. The starter includes a multi-pole DC controlled contactor which is interlockingly coupled to an overload relay. The overload relay has a simplified interlocking connection to the contactor, which when made, corresponds to an abutting electrical connection between the contactor and the overload relay also being made. The contactor further has a guiding pin that promotes even contact closure within the contactor.

A pair of pivoted links positioned at opposite sides of a movable armature and reversely oriented with respect to each other, have a pivotal connection at their opposite ends to a movable contact carrier and intermediate their ends to the armature whereby movement of the armature is amplified in movement of the contact carrier to permit reduction in the air gap between the armature and electromagnet core without incurring a corresponding reduction in contact carrier movement.

In a molded case circuit breaker with an interchangeable thermalmagnetic trip unit, the C-shaped heater transformer core is permanently held in place in the casing by a load bus strap with the gap in the core facing the trip unit. When the interchangeable trip unit is inserted into the molded casing, a magnetically permeable member mounted in the trip unit is aligned in the gap in the heater transformer core. The bimetal of the trip unit is fixed at one end to an electrically conductive sleeve surrounding the magnetically permeable member and forming the secondary of the heater transformer. The length of the magnetically permeable member is selected to establish the current conditions at which the bimetal trips the circuit breaker. The bus strap has an off-set section forming a first shoulder against which one wall of the housing of the interchangeable trip unit seats, and a second shoulder against which a pole piece backed by the heater transformer core seats to fix a gap between the pole piece and the armature in the interchangeable trip unit providing the instantaneous magnetic trip function.

A trailer hitch particularly for pick-up trucks and other relatively light towing vehicles having an improved hitch assembly including a retractable pin assembly in combination with guide members for limiting angular movement of a trailer behind the towing vehicle. An improved cylinder, pin and restrictor plate assembly provides a rebound or kick back to return or urge the jack-knifed trailer back to a position substantially trailing behind the truck. The cylinder improved in providing positive action in both retraction and extension of the pin.

Anti-jack-knife assembly

A subframe is coaxially pivotally mounted with a movable frame of the operating mechanism of a molded case circuit breaker and is locked to the frame by a bell crank pawl which is pivotally mounted on the subframe. A leaf spring assembly rigidly attached to the subframe overlies the movable contact finger to engage the same in the circuit ON condition of the circuit breaker to provide desired contact force. The bell crank pawl is released upon an incrementally small amount of initial movement of the movable contact arm in response to blow-open magnetic repulsion forces to release the movable contact finger for pivotal opening movement relative to the movable frame of the circuit breaker operating mechanism.

A molded insulator has a bottom wall, opposed sidewalls, and a transverse end wall extending between the sidewalls but spaced from the end of the bottom wall to define an opening in the bottom. A distribution lug is inserted from an open end of the insulator against the end wall, and under projections on inner surfaces of the sidewalls to trap the insulator against the end wall, and under projections on inner surfaces of the sidewalls to trap the insulator against up and down movement. The lug is attached to a circuit breaker terminal at the opening in the bottom to trap the end wall between the lug and the circuit breaker, blocking withdrawal of the insulator. A depending rib provides distal end support, while lateral ribs abut edges of barriers in the breaker housing to maintain the assembly properly aligned for electrical spacing.
