| 20110258996 | SYSTEM AND METHODS FOR OPTIMIZING EFFICIENCY OF A HYDRAULICALLY ACTUATED SYSTEM - Systems and methods for efficiently operating a hydraulically actuated device/system are described herein. For example, systems and methods for efficiently operating a gas compression and expansion energy storage system are disclosed herein. Systems and methods are provided for controlling and operating the hydraulic actuators used within a hydraulically actuated device/system, such as, for example, a gas compression and/or expansion energy system, within a desired efficiency range of the hydraulic pump(s)/motor(s) used to supply or receive pressurized hydraulic fluid to or from the hydraulic actuators. In such a system, a variety of different operating regimes can be used depending on the desired output gas pressure and the desired stored pressure of the compressed gas. Hydraulic cylinders used to drive working pistons within the system can be selectively actuated to achieve varying force outputs to incrementally increase the gas pressure within the system for a given cycle. | 10-27-2011 |
| 20110258999 | METHODS AND DEVICES FOR OPTIMIZING HEAT TRANSFER WITHIN A COMPRESSION AND/OR EXPANSION DEVICE - Systems, methods and devices for optimizing heat transfer within a device or system used to compress and/or expand a gas, such as air, are described herein. For example, systems, methods and devices for optimizing the heat transfer within an air compression and expansion energy storage system are described herein. A compressor and/or expander device can include one or more of various embodiments of a heat transfer element that can be disposed within an interior of a cylinder or pressure vessel used in the compression and/or expansion of a gas, such as air. Such devices can include hydraulic and/or pneumatic actuators to move a fluid (e.g., liquid or gas) within the cylinder or pressure vessel. The heat transfer element can be used to remove heat energy generated during a compression and/or expansion process. | 10-27-2011 |

| 20120055145 | SYSTEMS AND METHODS FOR OPTIMIZING THERMAL EFFICIENCEY OF A COMPRESSED AIR ENERGY STORAGE SYSTEM - Systems, methods and devices for optimizing thermal efficiency within a gas compression system are described herein. In some embodiments, a device can include a first hydraulic cylinder, a second hydraulic cylinder, and a hydraulic actuator. The first hydraulic cylinder has a first working piston disposed therein for reciprocating movement in the first hydraulic cylinder and which divides the first hydraulic cylinder into a first hydraulic chamber and a second hydraulic chamber. The second hydraulic cylinder has a second working piston disposed therein for reciprocating movement in the second hydraulic cylinder and which divides the second hydraulic cylinder into a third hydraulic chamber and a fourth hydraulic chamber. The hydraulic actuator can be coupled to the first or second working piston, and is operable to move the first and second working pistons in a first direction and a second direction such that volume in the hydraulic chambers are reduced accordingly. | 03-08-2012 |

| 20090266407 | TRANSPARENT GLASS PANE PROVIDED WITH A SURFACE STRUCTURE - A method of manufacturing a transparent pane, in particular a glass pane, which includes on at least one of its main surfaces a surface structure including an assembly of specified individual motifs in relief, in particular pyramids, cones, or truncated cones, created by embossing or by rolling. A structure is created on the surface of the pane constituted by individual motifs, based on one or more basic motifs but which are distinguished from each other by their depth, their height, and/or the perimeter of their base area, and/or by the position of their peak with respect to their base. With this variation, formation of intensity peaks of the reflected light is prevented and at the same time a high quality of light trapping is obtained by panes suitable, for example, for solar applications. | 10-29-2009 |
| 20090320899 | TEXTURED PLATE COMPRISING ASYMMETRICAL PATTERNS - A plate of transparent material including, on its surface, a texture including a plurality of a feature in relief, whether in a form of depressions or projections. The feature includes a first face and a second face that are not mutually parallel, lines at a base of the faces being parallel. The first face forms, with the general plane of the plate, a larger angle than the angle formed by the second face with the general plane of the plate, the angles being angles inside the material if the feature is a projection, or angles on the outside of the material if the feature is a depression. The plate improves light transmission toward a photovoltaic cell, in particular when the plate is in a vertical position, for example on the surface of a noise barrier. | 12-31-2009 |
| 20100051093 | GLASS PANE WITH LIGHT-CAPTURING SURFACE STRUCTURE - Transparent panes made of glass or of synthetic material, which simultaneously create good light trapping properties by linear structural elements and allow a thermal treatment and hardening of the glass without warping. Groups of parallel elements for which the orientation of the longitudinal extension of the elements alternates from one group to another are formed globally on the surface of the substrate. Moreover, the parallel elements can include a curvature superimposed on their longitudinal extension, which makes it possible to obtain a non-oriented reflected image with a weak screen effect. These panes can be used as covering for photovoltaic components designed to use solar energy, and can also serve a decorative purpose in the construction industry, for example for glazed doors or panes for furniture. | 03-04-2010 |
