A cellular wireless internet access system which operates in the 2.5 to 2.68 GHz band and which must comply with complex government regulations on power levels, subscriber equipment and interference levels yet which provides high data rates to users and cell sizes of 1½ miles radius or more from base stations with subscriber equipment and antennas mounted indoors. Such base stations are mounted low and use spread-spectrum transmission to comply with interference rules with respect to adjacent license areas. An unidirectional tear-drop coverage pattern is used at multiple cells to further reduce interference when required. Time division duplex is used to allow the system to operate on any single channel of varying bandwidth within the 2.5 to 2.68 GHz band. Backhaul transmission from base stations to the Internet is provided using base station radio equipment, operating either on a different frequency in the band or on the same frequency using a time-division peer-to-peer technique. Different effective data-rates are provided by a prioritization tiering technique.

Cooling systems for providing cooled air to electronic devices are described. The systems can include large storage tanks or waste treatment systems to improve the efficiency of the plant and reduce impact on the environment.

A passively stable personal hydrofoil watercraft that has a floation device, wherein a user can ride in a prone, kneeling, or standing position. The watercraft includes a strut having an upper end interconnected with the flotation device and lower end connected with a hydrofoil. The hydrofoil greatly reduces the power required to travel at higher speed. The watercraft also includes a propulsion system connected to the hydrofoil. Both longitudinal and directional control of the watercraft is via weight shift, eliminating the need of any movable surfaces. The floation device, strut, and hydrofoil may be permanently interconnected or may be detachable.

A collapsible insulated bag designed to allow items retained within an inner pouch thereof to remain within predetermined temperature ranges for predetermined periods of time and wherein the bags are designed to be easily compressed or compacted for storage or shipment to end users. The bags include at least an outer reflective or paper/Kraft based film layer, an intermediate open foam or insulating batt layer, and the inner pouch layer.

The invention relates to biological compositions comprising yeast cells that can be added to animal feed which upon ingestion by an animal can reduce the odor of manure produced by the animal. The invention also relates to methods for manufacturing the biological compositions, and methods of using the biological compositions as animal feed additives.

A phosphor-based multi-coloured display is provided which includes a spatial light modulator comprising an addressable array of apertures each corresponding to a respective sub-pixel in the display; an array of phosphor regions each indexed to a corresponding aperture of the spatial light modulator; and a backlight which provides quasi-monochromatic light to phosphor within each of the phosphor regions. The phosphor within each of the phosphor regions, upon being excited by the quasi-monochromatic light of the backlight, emits light having a colour different from a colour of the quasi-monochromatic light, through the corresponding aperture of the spatial light modulator.

A system for regulating the temperature of multiple areas within a facility using multiple energy savings devices (ESD) that each regulate the temperature of individual rooms or areas within a facility having a central heating and cooling plant. The device includes a fan and thermostats to control the temperature in each room. A first thermostat is located within the energy savings device to activate a fan only when a baseboard-heating element, cooling element or conduit provides a pre-selected sufficient temperature level range to activate a fan. Another thermostat is located remotely in each room and communicates to each ESD to deactivate the fan when the temperature in any room exceeds or is less than the desired temperature level. The desired temperature level may be higher or lower than a main thermostat setting that controls the central heating and cooling plant, in accordance with a heating or cooling mode, respectively.

The present invention relates to a process and apparatus for processing agricultural waste to make alcohol and/or biodiesel. The agricultural wastes are subjected to anaerobic digestion which produces a biogas stream containing methane, which is subsequently reformed to a syngas containing carbon monoxide and hydrogen. The syngas is converted to an alcohol which may be stored, sold, used, or fed directly to a reactor for production of biodiesel. The solids effluent from the anaerobic digester can be further utilized as slow release, organic certified fertilizer. Additionally, the wastewater from the process is acceptable for immediate reuse in agricultural operations.

In accordance with particular embodiments, a method for managing power consumption includes receiving from a plurality of electricity relays an indication of a current state associated with each of the plurality of electricity relays. The method also includes receiving a power rate associated with a cost of power. The method further includes determining a threshold state based on the power rate and the current state associated with each of the plurality of electricity relays. The method additionally includes transmitting one or more control requests to one or more of the plurality of electricity relays. A first control request transmitted to a first electricity relay is based on the threshold state and a first current state associated with the first electricity relay.

Compositions, methods, and systems for manufacturing articles, particularly containers and packaging materials, having a fiber-reinforced, starch-bound cellular matrix. Suitable mixtures used to form the articles are prepared by first preparing a viscous preblended mixture comprising water, a gelatinized starch-based binder, and fibers having an average length greater than about 2 mm. The highly viscous preblended mixture effectively transfers the shearing forces of the mixer to the fibers. The final moldable mixture is then prepared by mixing into the preblended mixture the remaining starch-based binder, water, and other desired admixtures, e.g., mold-releasing agents, inorganic filler rheology-modifying agents, plasticizers, coating materials, and dispersants, in the correct proportions to form an article which has the desired performance criteria. The moldable mixtures are heated between molds at an elevated temperature and pressure to produce form-stable articles having a desired shape and a selectively controlled foamed structural matrix. The articles may be manufactured to have properties substantially similar to articles presently made from conventional materials like paper, paperboard, polystyrene, plastic, or other organic-based materials and have especial utility in the mass-production of containers, particularly food and beverage containers.

A process for the recovery of nitrogen from anaerobically digested liquid waste and for the collection of the nitrogen as nitrate compounds that can be used to produce fertilizer and compost, includes stripping ammonia from anaerobically digested liquid waste, and converting the ammonia into nitrates via nitrification. The stripping gas is heated above ambient atmospheric temperature to improve nitrogen recovery. The heat can be reclaimed by burning gases generated during the anaerobic digestion process.

A variety of compositions that are particularly applicable for removing one or more of resist, etching residue, planarization residue, and copper oxide from a substrate comprising copper and a low-k dielectric material are described.
