Abstract: A hitch assembly comprises a receiver body and a receiver tube. The receiver body includes a plurality of spaced-apart exterior walls defining an interior space therebetween. A first one of the wall defines an upper portion of the receiver body and a second one of the wall defines a lower portion of the receiver body. The receiver tube has a first end portion positioned within the interior space of the receiver body and a second end portion exposed at an opening in an edge portion of the receiver body. The first end portion of the receiver tube is pivotably attached to the receiver body for enabling the receiver tube to be pivoted laterally within the interior space.

Abstract: A system for communication on a chip. The system includes an on-chip communication bus including plural tracks, and a plurality of stations that couple a plurality of on-chip components to the on-chip communication bus, whereby the plurality of on-chip components use the tracks to communicate. Each station preferably includes an initiator that requests permission to transmit outgoing data over a track to another station and that transmits the outgoing data, an arbiter that evaluates requests from other stations and selects a track on which to receive incoming data, and a target that receives the incoming data. The initiator can be connected to a grant multiplexor for selecting a grant line, with the grant multiplexor further including plural smaller multiplexors distributed across the chip. Likewise, the arbiter can be connected to a track multiplexor for selecting a track, with the track multiplexor further including plural smaller multiplexors distributed across the chip.

Abstract: Propellant compositions are coated with an energetic deterrent coating which reduces the burning rate at the surface of the propellant grain and causes the propellant to burn progressively. The use of energetic materials, that are slightly soluble in the coating solvent, improve the burning properties of the propellant without decreasing the chemical energy.
