Abstract: A skirt for photovoltaic arrays provides a screen portion, a groove portion, and a separate coupling adapted to couple the skirt to the skirt of an adjacent photovoltaic array and to a photovoltaic module. Another embodiment provides a screen portion comprising an angled louver and is adapted to partially obscure an area substantially beneath a PV module in a PV array. A further embodiment provides an edge blocking skirt for a PV array comprising a screen portion adapted for mounting a bottom of the screen portion substantially close to a roof.

Abstract: A Pendulum Valve having Independently and Rapidly Controllable Theta- and Z-axis Motion. The valve actuator used in the present invention provides the benefit of wide open unrestricted flow of a pendulum valve coupled with the high-resolution and wide dynamic range flow throttling of a ball or butterfly valve. The actuator mechanism will include motor drives and associated control system so that the drives are closely coupled to give highly controlled motion. The drive assembly introduces a concentric shaft arrangement that, when coupled with the highly controllable motor drives, exploits a cam-follower arrangement to make the relative rotation between the two concentric shafts result in highly controlled theta and z-axis motion. Finally, the plate to seal spacing afforded is greater than previously possible with prior valve actuator mechanisms, thereby substantially reducing flow turbulence through the valve as the valve plate eclipses the valve ports.

Abstract: A Pressure Sensing Apparatus is disclosed. Also disclosed is an apparatus that provides increased pressure sensitivity without added cost and complexity in the electronic detector circuitry. The apparatus further is less sensitive to gravity, vibrations or other external influences. It is a still further object that the apparatus be available with a curved bellow head, formed with either concave or convex reflective surfaces. Other versions of the apparatus may have a deflectable focusing diaphragm that permits pressure detection responsive to the curvature of a diaphragm in response to pressure differentials across the diaphragm.

Abstract: An improved optic system for measuring and/or controlling displacement, force, pressure, position, or chemistry is disclosed. This apparatus allows for more accurate, robust, and economical communication between the transducer (or control input element) and the reader device (or control output), allows the use of a single optic fiber and/or or a gap for the communication link, and produces substantial insensitivity to attenuation due to mechanical, chemical, thermal, and radiation effects acting on the optic fiber or open space in which the signal propagates. It is also significantly immune to interference from electromagnetic radiation, since the link can be easily produced as a non-conductor which will not propagate unwanted electrical energy or lightning, and is intrinsically safe from igniting fires or explosions. It also facilitates use on rotating machinery and remote location of the transducer by the ability to transmit the signal across a large gap or air space.

Abstract: A Pressure Sensing Apparatus is disclosed. Also disclosed is a diaphragm-type pressure sensor comprising a planar ring with a blister formed on said planar ring. The planar ring diaphragm-type pressure sensor is designed to function as an integral part of the overall larger pressure sensing apparatus, although it also has other uses. The planar ring diaphragm type pressure sensor may have a blister which is either larger or smaller than the width of the planar ring depending on the intended use. Furthermore, the blister on the planar ring may be light reflective.

Abstract: An improved device for the measuring of weight or force is disclosed. This is an apparatus that allows for measurement of weight or force using a cantilever beam that is substantially insensitive to location of the weight or force within certain limits on the beam and is capable of correction for off-level conditions.
