Abstract: 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.

Abstract: A housing for a subsurface object locator has a bubble level vial for leveling surfaces using the housing and a scribe tip for marking a surface being probed with the locator.

Abstract: Disclosed herein is a hand-held clamp-type multi-meter capable of measuring current and other electrical characteristics. The clamp includes a hinged jaw which is openable in the current detecting mode of the multi-meter, but not in other modes.

Abstract: A fish tape reel assembly includes a housing having a peripheral wall defining an outer wall of a cavity having a center. A housing handle is attached to the peripheral wall, and a fish tape cassette is rotatably mounted in the cavity. The cassette rotates in the cavity to wind and unwind fish tape thereon to retract or extend the tape to and from the housing in a feed direction which is perpendicular to the housing handle. A handle on the cassette pivots to lock the cassette into a locked position which prevents the cassette from rotating. A fish tape end piece is wedge shaped to create a path between surfaces requiring separation.

Abstract: 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.

Abstract: A voltage tester has an indicator housing and two separate probes connected to the housing by lead wires. One or more visual indicators are provided on the top surface of the indicator housing which wrap around to the sides and front of the indicator housing, and the bottom of the indicator housing has a clip into which the probe handles may be snapped from the sides of the clip so as to hold the probes beneath the indicator housing with the probe tips extending forward of the indicator housing and spaced a distance apart so as to fit into the blade openings of an ordinary wall outlet.

Abstract: A non-contact voltage tester has a self-test feature so that when a switch clip of the tester is actuated, light and sound indicator devices are energized to give a single blink and beep, respectively, following which the tester is ready for probing for a voltage. The light and sound indicator devices also indicate the presence of a voltage when the switch is actuated and a voltage is detected at the probe tip of the tester.

Abstract: A security light has a quartz-halogen lamp, a photocell, a passive infrared sensor for detecting motion external to the security light, and a circuit which causes the quartz-halogen lamp to operate at about 50% of full brightness in the absence of detection of motion at night, to operate at 95% of full brightness for a predetermined time interval in response to detection of motion at night, and to be off while the photocell is detecting daylight. A switch allows the user to select a different mode of operation which is similar except that the lamp is kept off in the absence of detection of motion at night. A user-initiated override mode is also provided, which causes the lamp to continuously operate at 95% of full brightness until the photocell detects daylight or until the user disables the override mode.
