摘要： A hand tool which provides an alarm signal to a user as the tool approaches a live electrical wire is disclosed. The hand tool comprises a tool head and coupled to a handle. A non-contact voltage sensing circuit is provided in the handle of the tool. As the tool approaches a live electrical wire, the non-contact voltage sensing circuit detects the voltage across the air gap between the tool head and the electrical wire, triggering an alarm circuit. The alarm circuit provides a visual or audio signal to the user.

摘要： An electrical testing device has non-contact AC voltage sensing, single probe contact AC voltage testing and voltage metering functions. Non-contact voltage sensing is used to detect the vicinity of a live AC conductor and single probe contact sensing is used to determine which conductor of a number of conductors in the vicinity is live. More specific information about the magnitude of the voltage can then be determined using both contact probes. The electrical testing device automatically determines the type (AC or DC) and polarity (if DC) of a voltage applied to test terminals, and provides an indication of the voltage range (AC or DC), without the need to operate any switches or other electrical actuators.

摘要： A power hand drill or other power tool includes at least one of a detachable non-contact voltage sensing device and a detachable subsurface object locator for detecting the presence of an object beneath a surface being probed with the locator. The drill has a housing with a flat accessory mounting surface including coupling elements for coupling the sensing module to the drill. The accessory device includes a mating coupling element to engage with the coupling element in the drill housing. The non-contact voltage sensing circuitry includes sensing circuitry contained within a housing with an antenna that is positioned opposite a tool head of the power tool, and an indicator mounted to the module for indicating the presence of a voltage.

摘要： An electrical circuit finder has a transmitter which is plugged into one of the circuits of a building's electrical system and a receiver which is used to identify other elements of the circuit such as a circuit breaker, fuse, switch, electrical device or outlet. The transmitter induces in the circuit a high frequency current signal which is modulated at a lower frequency. The receiver, including a sensor wand and a receiver housing, is tuned to inductively detect the high frequency when placed in the magnetic field of the circuit and to produce visual and audible signals to the user which vary in intensity according to the detected signal. The user can thereby use his or her visual and/or audio senses to associate a circuit element proximate to the receiver with the circuit element connected to the transmitter.
