摘要： The present disclosure concerns an electrical injury protection system for protecting individuals working on or near a power circuit. In one embodiment, the system comprises a controller that is electrically connected to a power circuit and a detector that is carried by a user working. The detector has three or more electrodes mounted on the user's body which detect the electric field induced on the body by the power circuit. The detector is operable to detect the voltage between each pair of electrodes and activate an alarm if the voltage between any electrode pair exceeds a predetermined proximity threshold. If the voltage between an electrode pair exceeds a predetermined electrical-contact threshold, the detector transmits a tripping signal to the controller to activate a tripping mechanism, which de-energizes the power circuit. In certain embodiments, the controller can be used to monitor the de-energized condition of a de-energized circuit.

摘要： A personal electrical injury protection system is provided which can be worn by electricians, construction workers, or other individuals working around or with low-voltage lines (i.e. generally less than about 600 volts). The personal electrical injury protection system has both a proximity warning component which provides a warning of potential electrical hazards upon close approach to the low-voltage power line and an electrical contact protection component which turns off the power upon actual electrical contact with the power line. The present personal electrical protection system relies on a radio frequency transmitter attached to the worker or person to be protected and a radio receiver/controller connected to the power line. The radio frequency transmitter has a low frequency generator which is used for electrical-contact protection and a high frequency generator which is used for proximity warning.

摘要： In the process of drilling a concrete in a building, many times contact and damage can accidentally be made with existing electrical conduit and the wires inside, or plumbing pipes. This damage can be avoided with a device which can indicate a grounded metal, such as a conduit, plumbing pipes, supporting frames or metal beam, all of which may be grounded to the existing electrical system. A safety protection circuit is incorporated into a power tool and includes at least one LED indicator connected to a low voltage power supply and to the body of the power tool to be illuminated when contact with grounded metal occurs.

摘要： Disclosed is an electrical receptacle which is safe for children yet easy for adults to use. This electrical receptacle provides power only to a properly inserted plug and makes use of one or more sensors which are able to detect blade insertion, ground plug insertion, presence of the plug face motion near the receptacle face or a combination thereof. The receptacle includes a contact assembly adapted and configured to conductively couple each blade of the plug to a conductor, one or more sensors, and a control circuit; wherein the control circuit determines whether or not to provide power to the properly inserted plug by determining if substantially simultaneous insertion has occurred.
