Abstract: Disclosed is a slip hitch system for coupling and uncoupling trailers from tractors having a three point lift. The slip hitch system comprises a tractor component mounted directly to the three point lift or in other embodiments to a standard 3 point hitch connected to the tractor's 3 point lift. A trailer component is configured for mating with one or more trailers to be moved. A tractor plate on the tractor component is configured for seating within a trailer component capture space or the inverse. Elevation of the tractor's 3 point lift consequently lifts the trailer component and trailer tongue for trailer relocation. Once relocated, the 3 point lift is lowered and the trailer and tractor components are separated while the operator remains in the tractor cab. Also disclosed are various locking mechanisms between the tractor and trailer components and methods of use and integration of power take-off.

Abstract: A system includes an optical device configured to emit light toward a build area, and an optical sensor configured to detect reflection of the light off the build area. The optical device operates at a first operating setting or at a second operating setting. The optical sensor receives reflection of the light emitted from the optical device operating at the first operating setting and reflected off the build area to determine one or more of a position, an orientation, or a shape of an object disposed on or within the build area. The optical device operates at the second operating setting to emit the light to additively form onto the object disposed on or within the build area.

Abstract: An interface module for coupling a VMEbus channel to a Universal Common Data Point channel and exchanging data signals in either direction. The module responds to protocol handshake signals from the originating channel, accepts a multi-word message-block, and provides handshake signals to notify the destination channel of message to be delivered. The module then transfers the message-block to the destination channel.
