Appl. No.:

13/338031

Inventors:

Paul M. Cruz - San Diego CA, US

Assignee:

International Safety & Development, LLC - El Cajon CA

International Classification:

H02J 4/00

US Classification:

307127

Abstract:

Embodiments disclosed herein relate generally to a device for correcting the polarity of electricity in a circuit. In direct current circuits, a positive voltage received from a power source will exit the device at a predetermined output regardless of which input of the device received the positive voltage. In alternating current circuits, one or more currents received from a hot output(s) of a power source will be connected to a predetermined output(s) of the device regardless of which input(s) received the current(s).

Appl. No.:

13/487970

Inventors:

Paul Cruz - San Diego CA, US

International Classification:

F17C 1/00
B65D 30/02

US Classification:

220581, 383 3, 22056001

Abstract:

The present invention is directed, in part, to an apparatus and methods related to an expandable storage tank for compressed gas, the storage tank prepared from a puncture resistant, flexible fabric material in which the storage tank is expandable to a desired volume when inflated and when deflated. During periods of non-use the storage tank is retracted in a compact and folded manner to save space compared to when the tank is inflated. The storage tank is utilized by employing its use in conjunction with a traditional air compressor and can be configured with or without a rigid outer shell that expands in relation to the amount of compressed air transferred into the expandable storage tank.

International Classification:

H02H 3/08

H02S 40/34

Abstract:

This disclosure provides systems, methods, and apparatuses for a power control system device housed in a subpanel, that allows for multiple alternative energy inputs as well as providing an islanding feature, which allows a homeowner to receive alternative energy power when the utility power is lost. For example, in a system that includes an electrical service panel main with a main circuit breaker that is connected directly to a utility electrical source, which may have one or more secondary circuit breakers that back-feeds current from an alternative energy source, there is provided an apparatus that: monitors current from both circuit breakers and prevents excess power from overheating the service panel and/or the wiring to the main circuit breaker; may have multiple spaces for circuit breakers that may be connected to multiple alternative energy sources; and may continue to feed specific loads to the home when utility power is lost and one or more alternative energy sources are available.
