Abstract: A heated cabinet including door assembly having a door positioned between opposing jambs of a door frame, wherein the door is pivotable, about a pivot axis, between an open position and a closed position. The door assembly includes a motor assembly operably connected to the door to pivot the door about the pivot axis and a control board operatively coupled to the motor assembly. The door assembly further has a first break beam emitter mounted to one of the opposing jambs and a first break beam receiver mounted to another of the opposing jambs and operatively connected to the control board. The first break beam emitter and first break beam receiver are disposed along a beam axis extending parallel to the pivot axis and proximate to an edge of the door adjacent to the pivot axis. The door assembly is configured such that interruption of a beam projected between the first break beam emitter and the first break beam receiver alters operation of the motor assembly.

Abstract: Motorized door assemblies having a door pivoting about a pivot axis extending across opposing jambs. In one aspect, the assembly includes a motor assembly having a motor, drive gears, slip clutch, and driven shaft connected to the door to pivot it about the pivot axis. The slip clutch includes a clutch plate slideable along the driven shaft, a drive plate driven by the motor via the drive gears, and a clutch spring urging the clutch plate into engagement with the drive plate, where the clutch and drive plates have profiled and counter-profiled faces. In another aspect, a break beam emitter and receiver are mounted to respective ones of the opposing jambs along a beam axis extending parallel to the pivot axis and proximate to an edge of the door opposite the pivot axis. Interruption of a light beam projected therebetween alters operation of a motor assembly.

Abstract: Methods, systems, devices and apparatuses for a heads up display (HUD) unit assembly. The HUD unit assembly includes a HUD guard device. The HUD guard device has a first elongated member. The first elongated member is position on one or more surfaces of the HUD unit and along an edge of the HUD unit and is configured to protect the one or more surfaces of the HUD unit and the edge of the HUD unit during installation of an instrument panel. The HUD guard device has a first leg member and a second leg member. The first leg member and the second leg member each have a first end and a second end. The first ends are coupled to the first elongated member and the second ends are configured to couple and interface with the HUD unit to support the first elongated member.

Abstract: A duplex transmission circuit using electronic components in place of either the multiple winding polar relays or combinations of differential amplifiers currently being used. In the circuit, algebraic additions and subtractions of voltage are performed and the results compared within an operational amplifier to produce the known outputs for E and M signaling in telecommunications systems. An additional operational amplifier is provided to produce a delayed response to signals of longer than a predetermined duration.

Abstract: An elongate rod is formed with an "S" shaped terminal portion at one end for providing an inner, or first, downwardly-open loop-adapted to be engaged by a member to be supported, and an outer, or second, upwardly-open loop adapted to restrain a member bearing thereagainst. The other end of the rod terminates in means for either securely, though releasably, anchoring the rod to a portable support base which is adapted to be affixed to a support surface, or means for securely, though releasably, anchoring the rod to a support surface, per se.
