A lighting fixture utilizing light emitting diodes and easily reconfigurable lenses to provide customizable lighting patterns to more efficiently illuminate work or storage areas.

A method for limiting loads in a wind turbine by using measured loads or wind speed to increase the minimum pitch angle for extended periods. The minimum pitch angle will be allowed to relax down to the default when load excursions diminish. The method will allow turbines to capture more energy by operating in higher wind speeds and / or utilizing larger rotors without additional loss of fatigue life.

An energy service business system includes a database which stores past data about an energy consumption of a facility before taking energy-saving measures, a measurer which measures present data of the energy consumption after taking the energy-saving measures, and a calculator which calculates energy curtailment quantities facility before and after taking the energy-saving measures. The past data in the database are stored in a form correlated with data of a production quantity, and the measurer measures the present data of the energy consumption together with data of the production quantity after taking the energy-saving measures. The calculator retrieves the past data having production quantity data within a set allowable range corresponding to the measured present data having production quantity data, and calculates the energy curtailment quantities by comparing the retrieved past data having production quantity data and the measured present data having the production quantity data.

An oxygen-based biomass solid fuel combustion system and method has an air separator for separating oxygen from air providing a supply of oxygen for feeding oxygen to a solid fuel combustion chamber. An airlock feeds a metered amount of solid fuel to the solid fuel combustion chamber. A burner stage having a firetube for collecting fuel gases from the solid fuel combustion chamber combusts the collected fuel gases with further oxygen from the separator and heats a boiler to generate steam. A heat utilization device (e.g. an electrical generator) may be connected to the steam boiler. Nitrogen-free diluent gases (e.g. argon and carbon dioxide) are used to control combustion process temperatures. The usable heat energy and useful byproducts are extracted from the different stages of the process.

System for controlling a door enabling driving from an initial position of its travel in a first direction at a speed v1 as far as a final position, said control system comprising a safety function comprising means for keeping a door in operation despite its having suffered an impact against an obstacle situated on its travel and enabling it to continue its initial movement automatically as soon as said obstacle is removed, through a design reconciling a sufficiently high normal speed of movement v1 of the door with the intention to prevent damage both to the obstacle and to the door by reducing the speed to v3<v1 close to the stored position of the impact.

The transparent polycrystalline optoceramic has single grains with a symmetric cubic crystal structure and at least one optically active center. The optoceramic has the following formula: A2+xByDzE7, wherein 0≦x≦1.1, 0≦y≦3, 0≦z≦1.6, and 3x+4y+5z=8, and wherein A is at least one trivalent rare earth cation, B is at least one tetravalent cation, D is at least one pentavalent cation, and E is at least one divalent anion. The method of making the optoceramic includes preparing a powder mixture from starting materials, pre-sintering, sintering and then compressing to form the optoceramic. Scintillator media made from the optoceramic are also described.

The invention describes a method of preparing magnetic ferrites from layered precursors in which Fe2+ is first introduced into the layers of layered double hydroxides (LDHs) in order to prepare Me-Fe2+—Fe3+ LDHs, and then by utilizing the easily oxidized nature of Fe2+, binary or multi-component ferrite materials containing Fe3+ in a single crystalline phase can be prepared. Values of the saturation magnetization of ferrites prepared by the method are significantly increased compared with ferrites prepared by traditional methods. Because the metal elements in the layered precursor have the characteristics of a high degree of dispersion, high activity and small particle size (average particle size 40-200 nm), no milling is required before calcination, thus simplifying the production process, shortening the production period, reducing capital investment in equipment and economizing on energy costs. In addition, the method does not corrode production equipment and does not pollute the environment.

A high-intensity LED lighting system is presented whereby one or more LED lighting fixtures are affixed to an elevating structure, the elevating structure having a substantially continuous internal pathway. Said pathway can be used as a conduit or duct for pressurized air which is introduced at or near the bottom of the elevating structure and forced upwardly toward the lighting fixtures so to provide cooling of one or more components of the lighting fixtures so to, ultimately, improve the efficacy of the LEDs contained therein. A method of designing lighting systems, including analysis of whether or not to add air cooling to increase light source efficiency is also disclosed.

This disclosure relates to controlling unwanted traffic to a device (40) in a communication network (30). The idea is to provide a more fine-grained control of incoming packets or connection attempts, by using an inclusive firewall (10) i.e. a firewall operating on “white-listed” traffic to a device (40). The disclosure, relates to a method for controlling a data flow to a device in a communication network, using a firewall located in the path between said device and a source node. The method comprises receiving (210), in said firewall, at least one data packet of said data flow. The firewall then reads (220), a predefined selection of bits of said at least one data packet, wherein the selection of bits is contained in at least one field of said data packet. The at least field or fields, including the selection of bits, carry a first type information. The firewall then forwards (240) the at least one data packet to the device, if selection of bits fulfills a policy of said device. The policy is defining requirements by which packets to said device are solicited. Hence, the solicitation of packets is a second type of information carried by said selection of bits. The disclosure further relates to a methods controlling a data flow, as well as to a firewall (10), a source (20) and a device (40).
