Abstract: A frequency controlled oscillator (100) is manufactured using an array (200) of mechanically interconnected oscillator bases (110) having component cavities (130) and wiring patterns therein. A frequency control component (120) serves as a cover for a cavity within the array, and in addition is electrically connected to oscillator components (140, 150) mounted within the cavity to regulate the frequency of electrical oscillation. Both the oscillator bases and finished oscillators may be tested while still in the array, prior to being separated from each other. In a most preferred embodiment, the array of oscillator bases are manufactured from a polymeric sheet material laminated with electrically conductive traces. The polymeric sheet material is selectively punched or formed prior to lamination so that intermediate and upper layers (112, 113) have predetermined sections removed.

Abstract: A solar powered cutting, shaping, and polishing device is disclosed. In the preferred embodiment a large concave parabolic reflector is mounted on an X and Y axis rotatable (telescope type) mount and directed towards the sun. A smaller convex parabolic reflector is mounted on an adjustable support structure attached to the large concave reflector such that the two reflectors can be made to share, or nearly share, the same focal point. Mounted between the large and small parabolic reflectors on an additional rotatable mount is a flat reflector. The large and small parabolic reflectors are used to concentrate solar energy to a desired and adjustable focal point. The flat reflector can then be used to direct the concentrated energy across a material in an operator-determined pattern. Depending on certain factors associated with the material and the positioning of the focal point, the material can then be cut, shaped, or polished as the user desires.
