  • Patent number: 8194381
    Abstract: An electrical ground transient eliminator assembly for attenuating high frequency transients and protecting a continuous attenuator circuit of the assembly from overheating due to excessive transients generated on an electrical load is provided. The electrical ground transient eliminator assembly includes a continuous attenuator circuit, which is electrically coupled in parallel to a relay. The assembly includes three lead wires, which are interconnectable to an earth ground line, a neutral line and a load ground of a system that has an electrical load coupled to external AC power lines.

  • Patent number: 8054191
    Abstract: A signaling device for electrical monitoring devices, in particular for short circuit and/or ground fault indicators, and for optical, visually perceptible signaling with at least one luminous element is provided. The signaling device has a housing having a housing wall and a region formed in the housing wall so as to cover the luminous element. A printed circuit board is disposed in the housing. The luminous element is arranged within the housing and directly on the printed circuit board. The housing wall is formed such that it is at least light-transmissive in the region.

  • Patent number: 8007555
    Abstract: A panel air filter assembly, for use in heating, ventilating and air conditioning (HVAC) systems, which has a single filter element with multiple portions. The single filter element is sectioned into substantially equally-dimensioned and separate filter portions. Each of the filter portions includes a specific type of medium and is distinct from one another, so as to remove different types of contaminants from the outdoor supply air before entering heating, ventilating and air conditioning systems. A waterproof paperboard frame securely supports the filter element at the filter element's marginal edges.

  • Patent number: 7956763
    Abstract: A faulted circuit indicator device for mounting on an overhead conductor cable for electrical power distribution systems to detect an abnormally high electric current therein includes a housing having an enclosure formed therein and current sensing circuitry for detecting the presence of the abnormally high electric current in the cable. An indication unit is responsive to the current sensing circuitry to produce a visual indication in the presence of the abnormally high electrical current. A clamping mechanism formed of a yoke and a pair of opposed pressure plates is disposed above the housing for securely mounting the cable therein to detect the abnormally high electric current. Compression springs are provided for resiliently urging the pair of opposed pressure plates upwardly for automatically trapping the cable in a fixed central position between the yoke and the pair of opposed pressure plates.

  • Patent number: 7878585
    Abstract: A foldable chair, which includes a forced air cooling system. The foldable chair includes a frame member. A flexible seat, which includes a meshed back rest suspends from the frame member. A fan bag, which has a pocket, is attached to the meshed back rest of the flexible seat. A fan is located at the bottom of the fan bag and is electrically disconnectable to a re-chargeable power source that is housed in a housing, which has an ON/OFF toggle switch so as to supply power to the fan.

  • Patent number: 7818824
    Abstract: A portable baby sanitizer with air pump device is provided which allows a user to activate a pressurizable chamber, that will dispense a multiplicity of liquid streams onto, and in order to cleanse, a baby's bottom. The sanitizer device includes the pressurizable chamber which has an air pump and an air release valve. The chamber is in direct fluid flow communication with a seat. The seat contains a liquid holding reservoir which dispenses a liquid spray, when the air release valve is engaged, through a plurality of discharge holes that are disposed along the inner rim of the seat. The sanitizer device can be used in conjunction with an independently transportable stand or in conjunction with a standard toilet.

  • Patent number: 7579783
    Abstract: An insertable flashlight adapter device for use in an ordinary flashlight having a lamp includes a disc-like shaped housing unit. Electronic circuitry is disposed within the housing unit for selectively operating the flashlight in at least three different modes. The electronic circuitry has a voltage comparator for determining which one of the at least three different modes the flashlight is being operated. The electronic circuitry also has logic and control means for selectively interrupting current to the flashlight lamp so as to cause the at least three different modes of operation. The logic and control means includes a first timer for monitoring a first time interval between mode changes in the voltage comparator and a second timer for monitoring a second time interval between a power-ON and power-OFF state of the flashlight lamp.
