Appl. No.:

13/592775

International Classification:

B60W 20/00

US Classification:

701 19, 701 22, 180 65265, 903930

Abstract:

A power system housed in modules or containers may be located as a unitary structure for example secured to a locomotive platform, allowing easy retrofits. A control subsystem may maintain an RPM of a prime mover at minimum that still provides an expected level of power from an electric machine for any one of a finite number of throttle settings. The control subsystem may dynamically adjust loads between various combinations of series and/or parallel couplings. A set of processor executable instructions may be configured for specific platforms by selecting appropriate set of values based on number of loads (e.g., driven axles), rating (e.g., horse power), other criteria (e.g., manufacturer, model, year). Characteristics may be determined and verified, and operation based on the outcome of such. A telematics system method logs and provides remote access to operational data, engine data, power system data, anti-idling overrides, unauthorized changes, and/or location.

US Patent:

40699714, Jan 24, 1978

Filed:

Nov 10, 1975

Appl. No.:

5/630292

Inventors:

David A. Swanson - Tempe AZ

International Classification:

F24J 302

US Classification:

237 1A

Abstract:

A building structure is provided with a conventional air conditioning unit and a solar energized air heater unit. Heated air is drawn from the solar unit and discharged into the structure in response to a thermostat. Means are provided for supplying heated air from the air conditioning unit when the supply from the solar unit is inadequate to maintain a predetermined minimum temperature. Radioscope means disconnect the solar unit from the system when available solar energy falls below a predetermined value. The structure may include a wall having air storage capacity therein for receiving and holding heated air from the solar unit, which air is subsequently delivered to the interior of the structure.

US Patent:

49020544, Feb 20, 1990

Filed:

Mar 20, 1989

Appl. No.:

7/325369

Inventors:

David A. Swanson - Phoenix AZ

International Classification:

E05B 1500

US Classification:

292254

Abstract:

A safety device for screen and storm secondary doors in which a movable rod is horizontally mounted on the door jamb proximate to the latch receiving mechanism. The closure of the inner or primary door urges the rod into position so as to disable the latching mechanism of the screen door. The opening of the primary door enables the rod to be withdrawn thereby permitting the secondary door to be opened.
