Abstract: A cover assembly is provided for preventing water infiltration into an in-floor receptacle fitting, such as a poke-thru fitting. The cover assembly includes a trim flange which overlies the fitting and is adapted to support at least one receptacle within the fitting. A cover plate is mounted on the trim flange includes access doors for selectively covering and exposing the receptacles. A first seal member is interposed between the cover plate and the trim flange for sealing against water infiltration therebetween. The first seal may be in the form of a planar gasket or O-ring. A second seal, in the form of at least one compressible gasket, extends around the perimeter of the floor opening and is adapted to be compressed between the trim flange and the surface of the floor. The cover plate may also include top and bottom portions and a third seal member interposed between the top and bottom portions.

Abstract: A wire protection grommet is constructed for installation in a wire pull opening in the cell of a cellular raceway. The grommet is sized for insertion through the wire pull opening and defines central passages extending through the opening. The central passage has a radiused portion defining a wire pull strain relief to prevent wires that pass through the grommet from being bent beyond a predetermined bend radius. The grommet is constructed to lockingly engage into the wire pull opening so that it is not displaced during use. The distal end of the grommet may be weighted so that the grommet correctly orients itself in the opening during installation. The grommet may also include a wire storage section around which excess wiring can be wrapped. Hooks may be provided for retaining the excess wire on the wire storage section. The grommet may include an opening or slot which extends to the central passage and which is sized to permit wires to be slid into the passage.

Abstract: An access cover for an in-floor receptacle fitting includes a door mounting member connectable to the fitting at a location that overlies the receptacles carried by the fitting. A pair of access doors are slidably connected to the door mounting member for movement between closed positions at which the doors abut one another and overlie the at least one receptacle, and open positions at which the doors are laterally spaced from one another and the at least one receptacle is exposed. A seal member is adapted to seal against moisture infiltration between the access doors when the access doors are at their closed positions. The seal member may include a compressible seal carried by at least one of the access doors. Preferably the compressible seal members are carried by each of the access doors and are positioned to abut one another when the doors are at their closed positions. The compressible seals may be formed from a compressible polymer that is co-molded with the access doors.

Abstract: An access cover for a receptacle fitting includes a cover plate connectable to the fitting at a location overlying a receptacle carried by the fitting. An access door includes a first portion slidably connected to the cover plate for movement between open and closed positions. The access door also includes a second portion having a first end pivotally connected to the access door first portion. The second end of the door second portion pivots to a first position overlying the receptacle in response to movement of the access door first portion towards its closed position, and pivots to a second position at which the receptacle is exposed and accessible through the cover plate in response to movement of the access door first portion towards its open position. Pivot features are formed on the cover plate and/or the access door for imparting rotational forces on the door second portion as the door first portion is slid between its open and closed positions.

Abstract: An apparatus and method for protecting integrated circuits from electrical overstress and eletrostatic discharge is provided. The apparatus includes a primary EOS/ESD protection device and a feedback circuit. The feedback circuit maintain the primary EOS/ESD protection device in an off state during normal operation of the integrated circuit and switches the primary protection device to an state when an EOS/ESD event occurs at a first input pad with respect to a second input pad of the integrated circuit.

Abstract: An apparatus and method for protecting semiconductor switching devices from damage due to electrostatic discharge is provided. The apparatus detects the occurrence of an ESD event, and turns the switching circuit to an operating state in which electrostatic charge is dissipated through the switching circuit. In embodiments of the invention, the switching circuit is a CMOS inverter circuit and the apparatus includes a PMOS transistor that upon occurrence of an ESD event couples an output of the inverter circuit to ground to discharge the electrostatic charge.
