  • Publication number: 20260186029
    Abstract: A non-contact voltage and current detector feature an elongated hollow housing containing a voltage-detecting circuit, a current-detecting circuit, a microprocessor, a software program, a key switch, and a battery source. Mounted on the housing is a flashlight and an audio source. When the key switch is pressed, a test program confirms the battery source has sufficiently charged, and the two detecting circuits are operating. When the key switch is pressed, the voltage-detecting circuit is energized and illuminates a voltage-detecting LED mounted on the detector's elongated body to indicate the presence of an AC voltage in a conductor when brought in proximity. The current-detecting circuit includes two or more current-detecting LEDs also mounted on the housing to display variations in the detected current signal. The microprocessor includes a timer function that turns off the detector at a selected interval.

  • Patent number: 10746811
    Abstract: A wireless receptacle tester system that includes an electrical tester with protruding terminal blades from a rigid housing. The tester includes an isolation circuit connected to an ACV/DCV converter and an Analog/Digital Converter. When a voltage is detected by, the tester, the voltage is automatically measured by the Analog/Digital Converter. Connected to the ACV/DCV converter is a DC Volt Regulator that regulates the 5 DC volts needed for the Analog/Digital converter, a microprocessor and a first Bluetooth module. The system also includes a Smartphone with a display and a second Bluetooth transceiver configured to pair with the first Bluetooth module. Loaded into the working memory of the Smartphone is a voltage display application. When the Smartphone is operated in the vicinity of the tester and the voltage display application is activated, voltage information is automatically transmitted from the tester to the second Bluetooth transceiver and displayed on the display.

  • Publication number: 20190094263
    Abstract: The invention disclosed herein is a tool movement recording system that includes a tool movement module either built into an existing hand tool or assembled inside an attachable ancillary housing. The tool includes a primary measurement sensor that measures or senses' the tool's primary function or purpose. The primary measurement sensor is coupled to a microcontroller and may be connected to one or more secondary sensors, said as an accelerometer or gyroscope. The microcontroller is connected to a first Bluetooth transceiver configured to pair with a second Bluetooth transceiver located in a nearby Smart phone. The Smart phone includes a microcontroller with working memory and a software application configured to present the information received by the second Bluetooth transceiver and display the information on the Smart phone's display or into a save file.

  • Publication number: 20180321298
    Abstract: An improved wall receptacle wiring tester system that includes a wiring tester with protruding terminal blades from one end of a rigid housing and with one or more lamps to indicate wiring conditions of a wall receptacle. The tester includes an isolation circuit connected to an ACV/DCV converter and an Analog/Digital Converter, a microprocessor, and a Bluetooth module. When a voltage is detected by the tester, the voltage is automatically measured by the Analog/Digital Converter. Connected to the Analog/Digital converter is a DC Volt Regulator that regulates the 5 DC volts needed for the Analog/Digital converter, the microprocessor and the Bluetooth module. The system also includes a Smartphone with a built-in display and a built-in Bluetooth transceiver configured to pair with the Bluetooth module in the tester. Loaded into the working memory of the Smartphone is a voltage display application.

  • Patent number: 8583167
    Abstract: A warning system for wireless mobile telephones that notifies designated users and broadcast an audible sound when suddenly de-acceleration. The telephone is coupled to a wireless telephone transmitter configured to operate with a nearby compatible wireless telephone network. The telephone includes a display, a speaker, an internal accelerometer and a programmable, impact-activated software program loaded into its working memory. The software program when executed continuously monitors for triggering signals from the internal accelerometer. When a triggering signal is produced, the software program is activated into an alarm state which then performs the notifications tasks designated by the user during the setup steps. The software program is configured to presents various input menus on the display that enables the user to turn the system ON and OFF, selective an alarm mode to be used, select a pre-alarm time period, an alarm duration period, and adjust the sensitivity of the accelerometer.
