Abstract: A gladhand device for automatically coupling the air brake hose of a railcar to a railcar mover is disclosed herein. The automated gladhand device may comprise a gladhand body that is attached to the end of a railcar mover and configured to receive the gladhand attached to an air brake hose of a railcar. In various embodiments, the gladhand device may comprise a piston housed within a lower portion of the gladhand body that is configured to extend vertically above a top edge of the lower portion of the gladhand body. When air pressure is allowed to enter the gladhand body via an electrically controlled solenoid, the piston presses against the gladhand of the air brake hose and pneumatically seals a coupling between the air brake hose of the railcar and the railcar mover.

Abstract: A claw system for mechanical coupling a railcar mover to a railcar is disclosed herein. The claw assembly may comprise a set of arms and a set of claws each mounted on the interior side of one of the set of arms. When a railcar adjacent to a railcar mover on a set of tracks is positioned within a proximity of the railcar mover, the claw assembly may be utilized to grasp the air hose of the adjacent railcar. For example, the set of arms may be attached to the railcar mover via a motorized rail upon which the set of arms may be configured to move axially toward each other in a direction perpendicular to the tracks, thereby causing the claws to move toward each other and close around the air hose of the adjacent railcar. The claws may include openings configured to grasp the air hose.

Abstract: Embodiments herein provide for reverse engineering of integrated circuits (ICs) for design verification. In example embodiments, an apparatus receives a gate-level netlist for an integrated circuit (IC), generates a list of equivalence classes related to signals included in the gate-level netlist, determines control signals of the gate-level netlist based at least in part on the list of equivalence classes, determines a logic flow of a finite state transducer (FST) based at least in part on the control signals, and generates register transfer level (RTL) source code for the IC based on the FST.

Abstract: An assembly for use in an electrical power distribution system includes a housing that includes an interior space; an electrical apparatus in the interior space, the electrical apparatus including an electrical connection mechanism that is configured to move between at least two positions; an observation port through the housing, the observation port being configured to allow visual observation of the electrical connection mechanism in the interior space from an exterior of the housing; and an optical guide between the interior space and a light source. The light source is outside of the interior space and the optical guide is configured to deliver light from the light source to the interior space when the light source emits light.

Abstract: An insulated switchgear module is disclosed. In one example, the module comprises a vacuum interrupter, current exchange assembly, and end conductors disposed within an insulated housing. The insulated housing further comprises a tank containing an actuator mechanism for actuating the current exchange assembly. An insulating tray within the housing separates the vacuum interrupter from the components in the tank. The insulated tray has a shape that corresponds with the shape of the vacuum interrupter and the shape of the housing.

Abstract: A civil defense air powered siren includes an air powered tone generator, a compressed air tank, an air compressor, an air line with a control valve connecting between the compressed air tank and the tone generator. A pressure switch communicates with the compressor and the compressed air tank. The pressure switch activates the compressor to charge the compressed air tank when air pressure in the tank falls below a pre-selected limit. The control valve is remotely controlled preferably by a radio signal to cause the control valve to open the air line and supply the tone generator with air in order to cause a civil defense warning tone to be generated when it is appropriate to do so.

Abstract: An audio buffer includes one or more audio effect resources that modify audio data received from an audio data source. A first audio effect resource in the audio buffer receives audio data from the audio data source and modifies the audio data to generate a stream of audio data. Subsequent audio effect resource(s) in the audio buffer receives the stream of audio data from the first audio effect and further modifies the audio data to generate a stream of modified audio data. The stream of modified audio data can then routed from the audio buffer to a second audio buffer, or communicated to an audio rendering component that produces an audio rendition corresponding to the modified audio data.
