Filed:

Oct 29, 2004

Appl. No.:

10/976459

Inventors:

Michael E. Greene - Opelika AL, US
Victor S. Trent - Auburn AL, US

Assignee:

Archangel Systems, Inc. - Auburn AL

International Classification:

G01C 19/00

US Classification:

7350402

Abstract:

A motion sensor may detect linear and/or angular acceleration and/or angular velocity of a body relative to one axis, two orthogonal axes or three orthogonal axes. Movement of the body or reference structure may be detected relative to one or more spinning rotors. The rotor(s) may be suspended for rotation and/or other movement relative to the reference structure without physical contacting the reference structure. In one embodiment, the rotor(s) may be electrostatically suspended in such a way that movement of the rotor(s) relative to the reference structure may be detected.

Michael E. Greene - Birmingham AL

Assignee:

Solar Works, Inc. - Birmingham AL

International Classification:

F24J 302

US Classification:

126271

Abstract:

An improved, portable, inexpensive solar heater for water and similar liquids. The heater comprises a tank triangular in transverse cross section, the hypotenuse of the triangular shape being closed by a wall effective to pass solar heat energy into the contents of the tank. A pivoted cover is provided for the hypotenuse wall and the inner surface of the cover is reflective, thus to augment the heat received by the contents of the tank. Preferably the tank and cover are made of shells filled with heat insulating material.
