Abstract: An apparatus includes a support member having a proximal end securable to a substantially fixed surface and a distal end opposite the proximal end; a solar energy member mounted to the support member at a location between the proximal and distal ends of the support member, where the solar energy member includes a first portion and a second portion arranged such that the support member extends substantially vertically between the two portions and the two portions are rotatable about a first axis to adjust azimuth of the solar energy member and about a second axis to adjust elevation of the solar energy member; and a plurality of cables, where each cable includes a first end secured to the distal end of the support member and a second end secured to a substantially fixed position, where the cables are configured to resist a wind load acting on the apparatus.

Abstract: A solar energy system includes a support member secured to a substantially fixed location; a solar energy member mounted to the support member and including a surface operable to track in response to movement of the Sun; an actuator assembly coupled to the solar energy member and configured to periodically apply a torque at a first frequency to move the solar energy member in response to movement of the Sun; and a damper assembly including a spool, where the damper assembly is configured to reactively release and retract a cable about the spool in response to changes in the steady state load, and maintain the cable at a substantially fixed length released from the spool in response to a torque at a second frequency greater than the first frequency that is intermittently received by the solar energy member.

Abstract: By suitable use of screen-printed carbon ink patterning, combined with patterning of the solder-mask layer on the top (finger) surface, a compact capacitive touchpad pointing device has been realized using only a two-layer board as a substrate. The first layer, on the topside of the printed circuit board, combines both the horizontal and vertical sensor electrode traces. The second layer, located on the underside of the printed circuit board, is formed in the conventional manner by attaching the controller chip and/or related circuitry.
