Abstract: Disclosed is a method and apparatus for providing a light emitting diode and driving circuitry integrated into a component module that will retrofit common incandescent lightbulb applications. The disclosed embodiments will perform with high efficiency at a wide operating voltage range with a very small size allowing for the incorporation within the envelope and form of existing lightbulb bases. Therefore, a single universal LED light bulb module can be used to replace the dozens of conventional LED and incandescent lights currently being used. The electronic circuitries used to drive the LEDs are extremely compact and consequently can be incorporated in nearly any standard bulb base.

The display is configured to display identification information associated with the telephone line. Related methods and systems are also provided.

Abstract: The present invention is to provide a power supply control apparatus which can connect a ground to a suitable electric potential when the ground is disconnected. The power supply control apparatus includes a control circuit having a switch element and a switch control unit, and a load. One terminal of load is connected to a direct-current power supply through the switch element, and the other terminal is connected to a ground electric potential. The switch control unit has a ground terminal connected to the ground electric potential and outputting a ground current flowing toward the ground electric potential. The control circuit includes a bypass device having a load side bypass system for passing the ground current to the ground electric potential through the load when connection between the ground terminal and the ground electric potential is disconnected.

Abstract: A timing light for measuring timing of spark ignition has separate displays of engine RPM and timing advance. Another aspect of the invention provides a flashlight function which triggers the flash tube of the timing light to produce a constant bright light source for locating timing marks within an engine compartment. The flashlight function can be incorporated into a dual display digital timing light, or other timing light designs. A dedicated control on the timing light functions to place the flash tube in a continuous flashlight mode.

Abstract: A conventional flashlight is adapted for use as a circuit continuity tester. The flashlight has the usual hollow body containing the batteries, a bulb having one contact in communication with the positive battery terminal and the other contact connected, through an on-off switch, to a conducting, exterior portion of the flashlight, and thence to a conducting spring which completes the circuit to the negative battery terminal. The flashlight is modified by providing a passageway through the end cap which threads to the lower end of the body, passing a wire through the passageway, and soldering one end of the wire to a metal washer having a plastic coating on one side and the other end to a metal pocket clip which detachably connects to the body. The washer is placed in contact with the negative battery terminal with the plastic layer insulating the washer from contact with the spring.

Abstract: An improved testing structure is provided in a flashlight (or lantern) provided with an electrical continuity tester. The flashlight or lantern has an insulated body and a flashlight (or lantern) bulb and batteries in primary series circuit. The testing structure, which is formed in the flashlight (or lantern) body, includes a testing series circuit, which is electrically-coupled to the primary series circuit, and a testing site. The testing site includes a pair of converging, sloping, facing walls, separated by a floor, the floor being provided with a pair of spaced-apart channels. Two electrically-conductive strips of specifically-defined structure and orientation are provided within the testing site to repose within the pair of spaced-apart channels. The strips may be resiliently urged into coincident relationship with the walls of the channels.

Abstract: An improvement is provided in a combination flashlight (or lantern)/continuity tester having an insulated body and a (flashlight) bulb and batteries in series circuit. The improved tester, which is formed in the flashlight (or lantern) body, includes an entry site of a particular configuration into the interior of the body. The testing means includes a pair of electrically-conductive strips, each strip having a contact portion, adjacent to the body entry site and penetrating into the interior of the body. Each strip is also in electrical contact with the series circuit. The shape of the entry site is such as to guide terminals of the circuit element being tested into contact with respective ones of the strips. The electrical continuity of a fuse or light bulb is determined by the lighting of the bulb being tested and/or by the lighting of the lamp bulb of the flashlight.

Abstract: A compound hand tool which can be attached to or include a flashlight in order to provide a single tool which performs the combined functions of a flashlight, an electrical continuity tester, a light to illuminate the work, and either a screwdriver, an awl, a nutdriver, or a socket holder. The tool eliminates the need to carry a number of separate hand tools and makes it easier to hold the required tools while performing a task such as troubleshooting an electrical panel in the dark or changing fuses under the dashboard of an automobile.

Abstract: A device for testing continuity of coaxial cables and tracing coaxial cables through junction boxes and the like includes a cylindrical housing formed in penlight fashion with an LED at the distal end and a battery disposed therein. The proximal end of the housing is provided with a female coaxial fitting having the conductor receiving portion connected in the LED-battery circuit. A cable terminator is provided, including a male coaxial fitting in which the conductor portion is shorted directly to the shield-engaging portion. The cable terminator is secured to a distant end of a coaxial cable, e.g., far removed from a cable junction box. The female coaxial fitting is secured to one of many near cable ends within or exiting from a junction box; if the coaxial circuit is completed and the LED is illuminated, it is determined that the distant and near cable ends are opposite ends of the same coaxial cable.

The pieces are provided with connector elements which allow each of the pieces to fit together and the pieces are small enough to conveniently fit in the shirt pocket of a cable television technician. In the flashlight configuration, a battery pack (10) and a flexible flashlight assembly (18) are interconnected. In the continuity checker or cable identifier configuration, the battery pack (10) is connected to one end of a cable (28) and the detector section (24) and shorting plug (26) are connected to the other end of the cable (28). In the bandit splitter detector configuration, the battery pack (10) is connected to the detector section (24) which is connected to the cable (28).
