  • Patent number: 6581546
    Abstract: The present invention provides for animal containment through a system having a containment collar and GPS (Global Positioning System), RF (Radio Frequency), or INS (Inertial Navigation System) data, or a combination thereof, to define the perimeter of a containment area. A receiver is mounted to the containment collar, worn by an animal, which contains positioning electronics, memory and warning outputs. The user defines the perimeter by programming “waypoints” (positions on the perimeter) into the collar. The system provides an audible warning when the animal is within a user programmable distance of the perimeter, and then provides an adjustable correction, such as an electrical impulse to the animal when the perimeter boundaries are exceeded. Upon perimeter violation and initial correction of the animal, the system dynamically changes the position of the boundary encompassing the animal's current but prohibited position.

  • Patent number: 5430251
    Abstract: An electrical junction box has conductor sections in the form of contact rails inside the box. The box has sides with openings for passing power lines. Replaceable conducting strip holders hold the contact rails within recesses in the base of the box. Covers over the conducting strip holders have openings so that the contact rails are accessible from inside the box.

  • Patent number: 5383090
    Abstract: A modular electrical-energy distribution system has at least one conductor and a contacting device which makes it possible to establish, at essentially any point in the conductor system, a contact with the conductor. The tap or contacting devices essentially clamp onto or between conductor bars and therefore essentially permit all contacts to be made simply from one side of the conductor bars thereby reducing installation time.

  • Patent number: 5326933
    Abstract: An installation system for wiring of a building has at least one junction boxes connected together, with each junction box having a removable plug-in block disposed at the back thereof. The plug-in block has conductors therein with sockets for providing access to the conductors, so that essentially all of the necessary electrical connections needed for wiring the building can, by means of the sockets and corresponding plugs on the power lines and electrical accessories, be made by simply plugging together the plugs and the sockets.

  • Patent number: 4744098
    Abstract: A roulette calculator for recording and visually displaying the occurrence and number of winning numerals during the progress of play of a roulette game is disclosed. The calculator includes a keyboard having a key and visual display for each number of a roulette wheel. A power source and electronic circuit means are employed between the keys and visual display means to advance the count in the visual display means upon key stroke of a given key to thus visually display winning numerals and the number of times that numeral was a winning numeral. The layout of the keyboard and color of the keys correspond to the roulette table colors and layout. Additional keys and associated visual displays may be provided to record conditions such as the number of winnings of red vs. black or odd vs. even. The keys and visual displays are positioned within recesses to prevent miskeying.

  • Patent number: 4181395
    Abstract: A connector for a plurality of electrical devices, particularly switches and receptacles, to be installed adjacently or on top of one another in flush receptacle boxes. An insulated flat conductor has a required number of wires for at least two independently actuated installation devices. The flat conductor is connectable to a power supply line and to connecting lines. Contact blades are placed at predetermined intervals, required for the installation devices, on the wires. Tapping points are formed by the contact blades and are backed up by a support for the flush receptacle boxes and projecting beyond the flat conductor. The flush receptacle boxes are provided with a cut-out bottom area. The contact blades, moreover, have an easily detached insulation, and the wires have terminals for connecting to a power supply line and a connecting line. The support may be tub-shaped, and the wires may be fused in the support which may extend over the length of the connector.
