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.
