Filed:

Aug 3, 2007

Appl. No.:

11/833635

Inventors:

Karl A. Burkett - Austin TX, US

International Classification:

H02G 3/04

US Classification:

174 681, 174 72 A, 174 731, 70 571, 70 58

Abstract:

A locking conduit lid and method of use that can lock or secure wires inside a conduit such that is would be almost impossible for a would be thief to pull the wires out of the conduit. The locking conduit lid contains a conduit sleeve that is designed to be fixedly attached to the inside of a polyvinylchloride (PVC) pipe, rigid metal pipe, or any other existing pipe or conduit that contains electrical wires. The electrical wires are secured to the conduit sleeve such that they cannot be pulled out of the conduit sleeve. A locking conduit lid prevents access to the wires inside the conduit sleeve thereby preventing theft of the wires.

International Classification:

B60Q 1/00
B60Q 3/00
H05B 37/02

US Classification:

362459, 362147, 3621531, 362231, 362464, 362506, 315 77, 315 80, 315 82, 315153, 3151693, 3409081, 340958, 340985, 3408154, 340332

Abstract:

A variable lighting system (“VLS”) for optimizing object visibility at night by setting a base level of lighting, adding a variable light to that base level of lighting, and a synchronizing the timing and sequence of the base level of lighting and the variable lighting. The VLS varies the illumination by intensity, color, direction, or a combination thereof and optionally includes a detector for detecting motion, noise, and other occurrences. The VLS can be implemented as a fixed lighting source, a movable lighting source, or a vehicle mounted lighting source. The VLS improves visibility at night for viewers or motorists thereby reducing accidents and damage costs, saves energy, and improves the environment and enhances quality of life by reducing light pollution and light trespass.

Filed:

Sep 4, 2007

Appl. No.:

11/849743

Inventors:

Karl A. Burkett - Austin TX, US

International Classification:

H01H 9/02
H01R 13/46

US Classification:

2003321, 174520

Abstract:

A device and method that contains an electromechanical break away sensor that de-energizes power or stops the flow of electricity to a pole upon a vehicle colliding with the pole or otherwise activation of the sensor. The sensor is omni directional and operates regardless of direction of impact from the vehicle or activation and has the ability to disconnect power when the pole falls due to a shear impact such as when there is a collision or the pole falls due to tension created by wind or weight failure. The sensor may also be activated by an authorized user such as one that is performing maintenance on the pole.

Appl. No.:

15/452682

Inventors:

Karl A. Burkett - Austin TX, US

International Classification:

H01H 3/02
H01R 13/66
H01R 13/713

Abstract:

A physical barrier breach sensor is disclosed that contains a frangible material that, upon displacement, opens a microswitch that de-energizes power or stops the flow of electricity to an electrical device. Displacement of the frangible material causes activation of the sensor, such as due to a vehicle colliding with a streetlight pole containing the sensor. The device is omnidirectional, operating regardless of direction of impact from the vehicle or activation, and has the ability to disconnect power when, for example, a streetlight pole or other structure (e.g., a parking gate) falls or breaks due to a shearing impact (such as a vehicle collision) or due to tension created by wind or weight failure.
