Abstract: A frangible shunt link assembly includes a frangible link configured to conductively couple a current collector coupled with a vehicle and one or more components of the vehicle. The frangible link is configured to break responsive to the current collector being at least partially separated from the vehicle to interrupt a conductive connection between the current collector and the one or more components of the vehicle.

Abstract: A shunt apparatus includes a mounting bracket assembly configured for connection to a vehicle, an actuator connected to the mounting bracket assembly, and a shoe unit connected to the actuator. The actuator is controllable to move the shoe unit to an extended position where a conductive shoe of the shoe unit is positioned to contact a conductive first running surface on which the vehicle travels. The shoe unit includes a resilient biasing assembly that is configured to exert a force on the shoe, to press the shoe against the running surface during movement of the vehicle. Two of the shunt apparatuses may be attached to opposite sides of the vehicle. The shoes of the two shunt apparatuses are electrically connected to one another by an electrical cable. When the shoes are brought into contact with respective running surfaces, the running surfaces are electrically shunted for vehicle signaling purposes or otherwise.

Abstract: A charging system for an electric vehicle has an elongate enclosure having a plurality of sides and an at least partially open side. The enclosure defines a hollow interior. The charging system further includes a conductor rail disposed in the hollow interior and that is accessible through the at least partially open side of the enclosure. The conductor rail may be placed in electric communication with an electrical power source and thereby may be selectively placed in electrical communication with an electrical connector of an electric vehicle. The charging system may conduct electric current from the electrical power source to an electric power supply of the electric vehicle.

Abstract: A system and method for lowering a pantograph includes a frame that may be extended or retracted. The system and method may include various structure for retracting the frame and for increasing a rate at which the frame is retracted. In particular embodiments, an electric, pneumatic, or hydraulic motor may be used to retract the frame during normal operations, and a continuity circuit operably connected to the motor may accelerate the rate at which the motor retracts the frame.

Abstract: An interconnection device for connecting a plurality of LCD contacts with a plurality of base circuit contacts. The interconnection device includes a non-conductive body having a U-shaped notch located for self-aligning engagement with a LCD driver chip. In addition, the non-conductive body includes at least one conductive lead. The conductive lead includes a first contact and a second contact that emerge from the non-conductive body. The contacts of the non-conductive body engage corresponding contacts of the LCD and base circuit board when the non-conductive body is engaged in alignment with the LCD driver chip.

Abstract: An electromagnetic shield for a radiotelephone includes a frame and a shield insert that fits into the frame. The frame comprises a generally rectangular wall structure that forms a part of the housing for the radiotelephone. The shield insert is sized and shaped to fit into the frame and is retained in the frame by friction, interference fit, or snap features. A plurality of interchangeable shield inserts can be made to fit into a standard frame.

Abstract: A mounting assembly is used to mount a liquid crystal display (LCD) to a printed circuit board. The mounting assembly includes a display support which is mounted to the printed circuit board and supports the display in spaced relationship to the printed circuit board. A connector with integral spring contacts snaps into an opening into the display support to electrically connect the contacts on the LCD to the contacts on the printed circuit board. The connector extends over a top surface of the LCD display and functions as a mechanical retention element.

Abstract: Radiotelephones with electrically and acoustically shielded microphones which have a conductive elastomer grommet positioned intermediate of the housing and the printed circuit board is disclosed. The grommet is sized and configured to hold the microphone therein. The grommet provides a continuous shield along the receiving signal path defined by the length of the microphone, any associated signal connector, and the printed circuit board.

Abstract: A locking fastener for an enclosure cover includes base and cover components. The base includes a pair of L-shaped flanges disposed on an internal surface of the base and a notch formed in the internal surface of the base. The cover includes a plate beam having ends that engage the L-shaped flanges of the base when the cover is assembled with the base. The plate beam also includes a tab that forcibly engages the notch in the in base when the cover is assembled with the base. The locking cover arrangement provides an economical and effective arrangement for permanently securing a cover over an opening.
