  • Patent number: 10107840
    Abstract: The Signal Analyzer Generator is comprised of a small form-factor electronic device used for measuring and generating electrical signals. The electrical signal interface is comprised of a two-pin connector in which the two pins are spaced 0.1 inches apart such that they connect to prototyping breadboards using two-pin male or female header pins. The purpose of the specific spacing design is to take advantage of the existing hardware owned by potential users of this technology and completely eliminate the need for electrical test leads that would otherwise clutter the workspace. The Signal Analyzer Generator can measure AC and DC voltages, temperature, humidity and current; and it can also generate both sine- and square-wave electrical signals—all of which are commonly used by technicians, engineers and hobbyists.

  • Patent number: 9618538
    Abstract: For decades, a mainstay of electrical and electronic testing has been the conventional use of the multi-meter that used a pair of probes to connect the Device Under Test to the meter. This often proves inadequate for present-day testing because more than one simultaneous or alternate reading or the connection of another testing tool and the reading of its effect on the DUT is often required. The Dual-Function Switch and Lead set (DFSL) of the present invention provides a switch and lead set interfacing two multi-meters, or one multi-meter and one test device or instrument with the DUT, while using the traditional and convenient pair of probes and a simple finger movement on the DFSL. The DFSL facilitates these tests, their safety and integrity, and reduces the time of many test procedures.

The method includes the steps of during the OFF-phase of a vehicle signal lamp to be probed inducing a probing current by connecting an electric current generator to said vehicle signal lamp circuit, where the probing current is lower than the nominal current for the lamp in question. The next step is to detect the electric voltage level over the lamp circuit and determining vehicle signal lamp characteristics such as type and condition based on said electric voltage level detection. The result of the determination is that the signal lamp is a LED lamp being connected, when the detected voltage level is within a predetermined interval between a first voltage level and a second voltage level.

The leads may be attached to alarm sensor wires, and one voltage meter module displays the voltage across the sensor wires. The output voltage of the variable DC to DC converter may be displayed on the second voltage meter module. The variable resistor may be adjusted to vary the output voltage of the DC to DC converter to match the voltage across the sensor wires. Once the voltages are matched, the switch may be closed to place the output voltage of the DC to DC converter onto the leads and in parallel with the sensor wires.

  • Publication number: 20080129315
    Abstract: A detecting apparatus for checking a detected item of an electrically conductive fastener attached to a workpiece includes a lower checking member for supporting the workpiece, an upper checking member movably set above the lower checking member, an electrical source, a processor, and an indicator. At least one of the two members includes a checking unit, which touches with the fastener and together with the fastener forms a detecting circuit when the upper checking member abuts against the workpiece. The detecting circuit is connected to the electrical source. A closed or open state of the detecting circuit indicates whether the detected item is eligible or ineligible. The processor controls the indicator to show the checking result according to the closed or open state of the detecting circuit. The detecting apparatus can greatly improve the checking efficiency and reliability, and suits mass production.

  • Patent number: 6979787
    Abstract: A device for de-energizing an energized branch electrical circuit is described, as well as related processes. The device includes a circuit breaker, which itself includes a breaker switch, an input terminal for receiving current, and an output terminal for directing current out of the breaker. A plug is also incorporated into the device, so that the device can be inserted into an electrical receptacle in the branch electric circuit. One or more power indicators, such as an LED light or voltmeter, are also incorporated into the device. When the device is plugged into a receptacle of the branch circuit, the breaker switch can then be turned on, resulting in a short-circuit, which de-energizes the branch electrical circuit.

  • Patent number: 6940416
    Abstract: This invention relates to a limited range low voltage testing, regulating, and indicating device comprising a detector and low voltage measurer of magnitude in a switch-regulated power supply circuit wherein indicator LEDs are operated directly from a power supply wherein continually increasing current draw provided by shunt switching operates to cause the first display LEDs to “fade” in an overlapping pattern of activation, in and out with slight voltage changes. Increased voltage causes a second LED to turn on. Further increased voltage causes the second LED to turn off and a third LED to turn on. Shunt and series connected voltage regulators selectively exert control over the LEDs.
