摘要： A solar concentrator including a substantially-transparent optical element, a reflective material disposed on a convex surface of the optical element, an insulator layer on the reflective material, a conductive material that is thermal sprayed onto the insulator layer, and a solar cell mounted in a central region of the convex surface and electrically coupled to the conductive material. The optical element includes a flat surface disposed opposite to the convex surface and a concave surface defined in the flat surface. The convex surface and concave surface are arranged and the reflective material is deposited such that light passing through the flat surface is reflected by the reflective material toward the concave surface, and is re-reflected by the reflective material disposed on the concave surface onto an active surface of the solar cell. Thermal spraying the conductive material may include spraying a molten metal powder onto the insulator layer.

摘要： An electricity generation system (EGS) is provided that can be deployed at a point-of-use site (e.g. residence, business, etc.). In one implementation, the EGS includes a generator for generating electricity (where the generator includes a Stirling engine that uses gaseous fuel for a combustion fuel source), an interface for interfacing with an electrical infrastructure of the site as well as a power grid, and a controller for controlling the operation of the EGS. The EGS may be used in conjunction with the power grid, and may selectively provide electricity to the electrical infrastructure based upon instructions from a utility provider that manages the power grid, based upon an electrical load imposed on the electrical infrastructure, based upon the electrical capacity provided by the power grid, based upon cost considerations, etc. By taking some or all of these considerations into account, the EGS can adapt its behavior to fit changing conditions.

摘要： Embodiments generally relate to methods and apparatuses for generating ice. In one embodiment, a material is introduced to water, and the temperature of the combination of the water and the material is lowered until ice forms, the formed ice having a higher albedo than it would have had if the step of lowering the temperature had been carried out on the water without first carrying out the step of introducing the material. In one embodiment, the material is selected such that an aqueous solution of the material is alkaline. In another embodiment, a material is introduced to water, and the temperature of the combination of the water and the material is lowered until ice forms, the ice forming at a faster rate than the rate at which it would have formed if the material had not been introduced to the water.

摘要： A transport system for cut sheet media has a first and second cylinder to form a nip, a support subsystem to transport edges of cut sheets having at least one image into and out of the nip, and an array of contact points on each cylinder to make contact with the cut sheets without marking the image. A wheel for a print medium transport system has an outer rim having a series of contact points, an inner hub supporting a means to accommodate a drive shaft, and an internal spring connecting the outer rim to the inner hub. A method of transporting cut sheets in a printing system forms a nip between at least one pair of cylinders, each cylinder having an array of contact points, guides a first edge of a cut sheet into the nip, and uses the arrays of contact points to transport the cut sheets through one of either a fusing or drying process.

摘要： An improved fuel cell is described. The invention addresses the problem of mechanical failure in thin electrolytes. One embodiment varies the thickness of the electrolyte and positions at least either the anode or cathode in the recessed region to provide a short travel distance for ions traveling from the anode to the cathode or from the cathode to the anode. A second embodiment uses a uniquely shaped manifold cover to allow close positioning of the anode to the cathode. Using the described structures results in a substantial improvement in fuel cell reliability and performance.

摘要： A media path jam clearance apparatus installable in a supporting structure includes media drive mechanisms for moving flexible media through media paths and a rotatable, removable jam clearance element. Within the jam clearance element facing surfaces of guide elements define guide surfaces for media paths, with the guide elements having external surfaces capable of supporting the flexible media as it is wrapped around the external surfaces. A pivotal support element supports and enables rotational movement of the jam clearance element within the supporting structure. The jam clearance element may be partially or entirely extracted from the supporting structure.
