Abstract: A solar panel comprises a cell mounting surface and a cell array having a photon absorbent surface. Moreover, the cell array is coupled to the cell mounting surface such that the photon absorbent surface of the cell array is at an angular position different than the cell mounting surface. Furthermore, the cell array is a part of a system comprising a solar panel, a foundational base, and a tracking system. The system is enclosed within the foundational based and further coupled to a tracking system. The tracking system controls an angle of the panel and re-orients the position of the photon absorbent surface of the cell array to a position of the sun.

Abstract: The idea is to provide more output per footprint area of a solar cell array. This is accomplished by the arrangement of the individual solar cells and their orientation to the source or the sun is disclosed. The invention gives the optimum output per footprint area by two concepts; maintaining solar alignment to the array and cell arrangement in the array. Essentially cell output decreases as its alignment approaches parallel to the sun but there is a point where the angle is optimal like 75 degrees and the cells would be arranged at 15 degrees from normal to the sun.

Abstract: A resistive two sheet touchscreen that provides discrimination between objects touching the surface thereof. This is achieved by subdividing at least one sheet into a selected number of separated portions of selected configuration. Each of these portions is connected through a switch apparatus to circuitry for evaluating a signal on the separated portions corresponding to the position of touch. This switch can be utilized to deactivate any selected portion so that an object contacting this portion provides no signal to the circuitry. Any active portion that remains connected to the circuitry provides position information as with any touchscreen. Accordingly, for example, the touchscreen can be made insensitive to portions of a hand, while being sensitive to a stylus held by that hand. An embodiment utilizing a single resistive layer coupled with a conductive layer is described together with an embodiment utilizing two resistive layers, are described.
