Abstract: A scaffold rack may have a first side and a second side. An upright portion may be located between the two sides. The first side may have at least one pair of scaffold frame tubes adapted to selectively secure at least scaffold frame. The second side may have a first arm adapted to selectively support at least one walkboard thereon and a second arm adapted to selectively support at least one scaffold bracket thereon.

Abstract: A rack apparatus may have a plurality of uprights and stanchions coupled to a base, where the uprights and the stanchions may form areas configured to receive and support scaffolding and at least one working component. The base may be configured to be transported by a material handling device.

Abstract: AC powered logic circuits and systems including same are disclosed. According to one aspect, a system including a logic circuit powered using an alternating current (AC) power source includes at least one supply transistor connected to receive voltages of opposite phases from an AC power source such that the at least one supply transistor is strongly on during a first phase of the voltage of the AC power source and is strongly off during a second phase opposite the first phase of the voltage of the AC power source and at least one logic circuit connected to be powered by the AC power source through the at least one supply transistor and producing an output at an output terminal responsive to an input received at an input terminal.
