Abstract: A sign clip for attaching a sign to a post may include a front piece and two side pieces forming a square with an open side. The side pieces may each have a hook piece on the back to prevent the clip from moving forward. Compressible bumpers on the inside of the sign clip may either be pressed up against the post by the spring force of the side pieces, or may slip inside holes in the sign post. Clip pieces extending down from the front piece may hold a sign to the post. The sign clip may enable convenient attachment of the sign to the post without the use of tape, string, glue, ties, or other materials that may be difficult to remove.

Abstract: Systems, apparatus and methods are presented for multiphase inverter control in which PWM switching control signals are generated for operating inverter switching devices according to current feedback values, and a given inverter phase is identified in a given PWM switching cycle having the lowest low side duty cycle on-time. A phase current feedback value is selectively computed for the identified phase at least partially according to the low side current shunt voltage values corresponding to other output phases, and the phase current feedback values are updated with the computed phase current feedback value and the low side current shunt voltage values of the remaining output phases to provide feedback for closed loop PWM switching control.

Abstract: A safety device (14) for an electrical outlet (16) including a back cover plate (32) having a pair of vertically aligned apertures (34), (36) therethrough. A pair of shields (40), (42) are sized to obstruct the apertures (34), (36) in the back cover plate (32), to prevent access to dual sockets (24), (26) of a receptacle (22). A structure (44) on a front face (46) of the back cover plate (32) is for guiding the upper shield (40) to move upwardly away from the upper aperture (34) and the lower shield (42) to move downwardly away from the lower aperture (36) in the back cover plate (32). Components (48) are for biasing the shields (40), (42) on the front face (46) of the back cover plate (32). A front cover plate (50) has a pair of vertically aligned apertures (52), (54) therethrough. Elements (58) are for mating the front cover plate (50) to the back cover plate (32) cover the shields (40), (42).
