Abstract: A hand tool and an accessory which provide an alarm signal to a user as the tool or accessory approaches a live electrical wire are disclosed. The hand tool or accessory include a non-contact voltage sensing circuit. As the tool or accessory approaches a live electrical wire, the non-contact voltage sensing circuit detects the voltage, triggering an alarm circuit. The alarm circuit provides a visual or audio signal to the user. The hand tool can be selectively coupled to the tool head.

Abstract: A pet repellent plastic cover is placed over cords to prevent pets from chewing the cords. This cover prevents injury to the pet and damage to the cord.

Abstract: A power hand drill has a 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 having a pair of attachment tabs. The locator has a locator housing with a flat base and a pair of key hole slots engaged with the tabs for detachably mounting the locator housing to the accessory mounting surface of the drill housing. The locator includes sensing circuitry contained within the locator housing for detecting subsurface objects and has an object indicator mounted to the locator housing and connected to the sensing circuitry for indicating the presence of a subsurface object. A contoured surface on the locator housing provides a handrest for gripping when operating the drill.

Abstract: 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.
