Abstract: A social networking system allows users to upload information about themselves to a remote database, preferably over the Internet. Users are able to connect to other users thus establishing links. These links may be categorized based on the relationship between the users, e.g., family, friends, co-workers, etc. The uploaded information may also be categorized using the same categories of relationships. The information of each user may then only be sent to users having a connection category that matches the information category.

Abstract: A system and method for transmitting data on a power transmission line transmits power in the form of time-varying voltage and current. Data is transmitted by using micro electromagnetic pulses to modulate the electric field, which is present around the power transmission line as a result of the time-varying current.

Abstract: Electrical receptacles configured to eliminate arc faults rather than merely detect such faults with attendant circuit disconnection, the invention contemplates low-cost, child-safe electrical receptacles useful in residential situations and which can be fitted within the confines of single gang enclosures. The safety receptacles of the invention can be used in all use situations including both residential and industrial applications to increase safe use of electrical receptacles in residential applications in particular and to decrease industrial liabilities. In essence, the safety receptacles of the invention prevent arcing during insertion of a plug into the receptacle, during residence of the plug in the receptacle and during removal of the plug from the receptacle with a substantial load to the receptacle.

Abstract: Detection apparatus for sensing the operational state of an electric fence and thus an electric fence charger intended to maintain an electric charge on the fence, the invention and the several embodiments thereof find compatibility with known fence chargers whether pulse or continuous in appropriate supply voltage ranges. The detection apparatus of the invention includes a power supply such as a battery to drive a light source such as a light emitting diode which is caused to flash by circuitry carried by the apparatus, the apparatus being clipped to the fence at any location thereof to connect the circuitry to the electrical load on the fence. The light source operates in the event of a failure of the fence charger to perform properly including conditions ranging from complete failure to voltage drops of a predetermined degree or in the event of an open circuit such as can be caused by a separated fence conductor such as a fence wire.

Abstract: A method for making a paintball grenade includes adding a thickening agent, a coloring agent, and a mixing agent to an enclosure, such as a balloon. Water is added to the enclosure and combines with the thickening agent and the coloring agent to form a colored, gelatinous liquid. The mixing agent facilitates the mixing of the thickening agent and the coloring agent with the water. The enclosure can be thrown or launched during a game of paintball to eliminate players on an opposing team from the game.

Abstract: Power line installation wires which carry electricity to energize devices connected to the wires can also be used simultaneously to carry other electrical signals that convey information or control between devices connected to the wires. With regard to the disclosed power line communication system and method and related components and processes, each device to be connected to an electric power line installation can be uniquely identified (referred to as the device's electronic genetics) in such a manner that practical applications are not limited as to the number of devices connected to, or as to complexity of information or control effected by communications over, the wires of the power line installation. With its unique identity, any such device can be connected to any power line installation to communicate with any other such device connected to that installation so long as the identity information and linked operational files are within the system of devices connected to the particular installation.
