Filed:

Aug 5, 2004

Appl. No.:

10/911655

Inventors:

Leslie A. Beckwith - La Mirada CA, US
Randy V. Cruz - La Habra CA, US

Assignee:

Polara Engineering, Inc. - Fullerton CA

International Classification:

G08B 1/095
H04B 3/36
G01S 15/00

US Classification:

340944, 3404071, 367116

Abstract:

A 2-wire control system which communicates with a plurality of pole mounted push button stations of the kind that are found at a traffic light controlled intersection via existing pairs of underground wires over which power and data signals are transmitted so as to enable a visually impaired pedestrian to receive both audible and tactile signals regarding the flow of vehicular traffic through the intersection. The 2-wire control system includes a central control unit that is located at a traffic light control cabinet and is connected to a standard traffic signal light controller. The control unit includes a plurality of 2-wire output ports that are connected to respective pairs of the plurality of push button stations. The central control unit also includes a corresponding plurality of on/off controls and data interfaces by which each of the 2-wire output ports thereof is provided with the power and data signals to be transmitted to respective pairs of push button stations depending upon the entry of a pedestrian request and the illumination of a WALK or DON'T WALK message.

Appl. No.:

11/029595

Inventors:

Randy Cruz - La Habra CA, US

Assignee:

Power Probe, Inc - Brea CA

International Classification:

G06F 3/02

US Classification:

702 57, 702 60, 702 64, 702 65

Abstract:

Provided is an electrical test device having multi-meter functionality and being adapted to provide current sourcing to an electrical system for selective measurement of a plurality of parameters. The electrical test device comprises a conductor probe element, a power supply, a processor and a display device. The power supply is interconnected between an external power source and a probe element. The processor is connected to the probe element and is configured to provide an input signal to the electrical system and receive an output signal in response thereto. The output signal is representative of at least one of the parameters of the electrical system. The display device is configured to display reading the output signal which is representative of the parameter. The electrical device is configured to allow for selective powering of the electrical system upon energization of the probe element during measurement of the parameters.

Appl. No.:

13/404644

Inventors:

Jeff Whisenand - Fullerton CA, US
Randy Cruz - La Habra CA, US

Assignee:

POWER PROBE, INC. - Brea CA

International Classification:

G01R 31/02

US Classification:

324501

Abstract:

An electrical test device may include a power supply, a conductive probe element, and a spectral analysis block. The conductive probe element may be energized by a power supply. The probe element may be placed in contact with an electrical system under test and apply an input signal containing current for measuring at least one parameter of the electrical system. The spectral analysis block may be connected to the probe element and may receive an output signal from the electrical system in response to the application of the current to the electrical system. The spectral analysis block may analyze frequency spectra of the output signal and detect a broadband increase in energy of the frequency spectra above a predetermined energy threshold. The broadband increase in energy may be representative of the occurrence of arcing in the electrical system.
