Filed:

Jul 10, 2003

Appl. No.:

10/616542

Inventors:

William D. Buchanan - Azusa CA, US
Joseph F. Mohos - Burbank CA, US
Wally E. Rippel - Altadena CA, US

Assignee:

Aerovironment Inc. - Monrovia CA

International Classification:

H02J 7/04

US Classification:

307 62, 307 82, 320109

Abstract:

A charging system for simultaneously charging the batteries of a plurality of battery powered vehicles. The charging includes one or more DC-DC power converters having one or more charging ports configured to plug into the batteries. The DC-DC power converters are each configured to selectively connect to more than one charging port to selectively provide for higher port power levels. The DC-DC power converters connect to an AC rectifier through a DC bus. The AC rectifier connects to an AC power source having a limited power rating. The AC charging system also has a controller that controls the operation of the DC-DC power converters such that the total power draw on the AC rectifier does not exceed the power rating. The system is further configured such that the DC-DC power converters can drain selected batteries to obtain power for charging other batteries, thus allowing for batteries to be cycled.

International Classification:

H02J007/00

US Classification:

320112000

Abstract:

A watering connection is integrated with a battery charging connector to form an integrated charging and watering connector. The integrated charging and watering connector selectively couples fluid from a fluid supply and a charging voltage from a battery charger to one or more batteries of a battery pack. At an appropriate time, such as after charging or equalization of the batteries of the battery pack, the charger transmits a control signal to a fluid supply control valve. The control signal opens the control valve, thereby allowing cells of the batteries of the battery pack to be replenished. Check valves coupled to the cells of the batteries of the battery pack can be used to halt the filling of cells. Alternatively, a fluid level detector monitors the fluid level in the cells. If not adequately filled, the fluid level detector transmits a sense signal back to the charger. The charger then issues a control signal to open the fluid supply control valve. Fluid is then allowed to fill the cells until the fluid level detector determines that the cells are adequately filled.

Appl. No.:

7/660128

Inventors:

William R. Buchanan - Long Beach CA

Assignee:

Sevenstrand Tackle Corporation - Long Beach CA

International Classification:

A01K 8500

US Classification:

43 4228

Abstract:

A fishing lure, the combination comprising a lure head and a lure tail spaced apart longitudinally, the tail being longitudinally elongated; the head having a front edge, and two laterally spaced, elongated edges tapering rearwardly and toward the tail, the head having opposed faces with spacing therebetween substantially less than the length dimension of each the elongated edges, the head having weight substantially greater than the weight of the lure tail; and there being means to connect a fishing line to the fishing lure so that the line approaches a mid-portion of one of the head faces.

Appl. No.:

7/069048

Inventors:

William J. Buchanan - Playa del Rey CA

International Classification:

A61F 504

US Classification:

128 92Z

Abstract:

A method and apparatus to percutaneously reduce a bone fracture and to maintain reduction during percutaneous, limited open, or open fixation of the fracture. The apparatus comprises a movable part threadably engaged with a fixed part. The fixed part of the apparatus attaches to a rigid frame surrounding the site of the fracture. A surgical pin is threaded into a bone fragment and secured to the moveable part of the apparatus. Additional pins are threaded into the bone and rigidly secured to the frame. The apparatus allows controlled axial movement of the pin relative to the frame. A medical procedure employs this apparatus to accurately reduce a fracture percutaneously while percutaneous or limited open fixation is performed.
