Abstract: Systems and methods are provided for automatically classifying videos based on faces discovered in the videos, wherein the discovered faces are not known to be associated with a particular category of videos. The detected face is compared to a set of unknown faces to generate a cluster of unknown faces that each match with the detected face. A set of categorized videos is identified based on the cluster of unknown faces. One or more categories are assigned to the video based on categories from the set of categorized videos so that the video can be automatically classified based on the detected face even though the detected face is not associated with a known person.

Abstract: An identities collaboration system that comprises a Personal Service Provider (PSP) system for supplying specific user related personal service(s); means for assigning two different data files to each user opting-in to the PSP system, wherein one data file contains data representing the user identity at the PSP system and it assigned on a first domain, and the other data file(s) contains data representing the information regarding whether the user is opted-in, or another identity number that is related to the user identity at the PSP, and is assigned on a second domain.

Abstract: The inventive process converts cellulosic biomass into a gel-like state that is readily hydrolyzed by appropriate enzymes. First the biomass is mechanically reduced in size. The biomass is then mixed and kneaded with an aqueous solution of a hydrophilic polymer that acts as a conditioning agent or as a co-solvent. During mixing the cellulose (and hemicellulose) in the biomass swells and becomes hydrated forming a viscous gel-like material. The processed material can then be thinned through the addition of water whereupon hydrolytic enzymes are mixed into the material and rapid hydrolysis into free sugars takes place. Dextrins are effective hydrophilic polymers for conditioning biomass. Polyvinyl alcohol is a particularly effective conditioning agent for use with biomass when converted into a viscous gel by adding borate ions.

Abstract: Cellulosic biomass is reduced to a micropowder with particles having average diameters below 5-10 micrometers with a significant fraction of the particles have diameters below 1 micrometer. Biomass (e.g., wood, agricultural waste or other plant materials) is first processed into pieces having a maximum diameter of about 10 mm. This is then dried to reduce its water content to no more than about 15% by weight and introduced into a disruptor which reduces the particle size to about 1 mm. Next the biomass is processed with a disc mill where edges of rotating discs travel along a groove pressing and squeezing the biomass, thereby breaking the biomass pieces into smaller and smaller particles. The resulting micropowder is extremely susceptible to enzymatic or chemical hydrolysis into constituent sugars. In addition, the micropowder can be suspended in an air stream and burned directly to provide heat to boilers and similar devices.

Abstract: An aircraft-conversion method of converting a passenger aircraft to a cargo aircraft, includes selecting a passenger aircraft, and converting the aircraft to a cargo aircraft by changing a door of the aircraft to accommodate loading and unloading of cargo. The selecting step may involve an all-passenger aircraft, and the converting step may include removing all seats from the aircraft. A system for converting a passenger aircraft with a passenger door for passenger entry and exit to a cargo aircraft includes aircraft-door conversion structure constructed to replace the passenger door with a cargo door that allows loading and unloading of cargo on the aircraft via the cargo door. A converted cargo aircraft includes an aircraft body, and aircraft-door conversion structure constructed to replace the passenger door with a cargo door that allows loading and unloading of cargo on the aircraft via the cargo door.

Abstract: The present invention provides an improved control methodology for maximum power point tracking (MPPT), anti-islanding, and output current regulation for distributed generation sources connected to a utility grid. The control includes enhancements for MPPT and regulating the inverter output-current that is sourced into the utility grid. In addition, the functions associated with MPPT, anti-islanding detection and output current regulation are integrated together; the MPPT algorithm operates in conjunction with the anti-islanding detection, and the output current regulation operates in conjunction with the MPPT algorithm.

Abstract: A fluid pump integrated with a motor, a fluid pump/generator device, a rotor for a fluid pump/generator device, a stator for a fluid pump/generator device and a method for pumping fluid are disclosed. Specifically, a fluid pump includes a motor rotor having a plurality of magnetic vanes that electromagnetically interact with a plurality of magnetic poles of the motor stator such that the rotor functions simultaneously as the impeller for the pump and rotor for the motor, with fluid flowing through channels on the rotor. Pump and motor are tightly integrated into one single device so that the number of parts is reduced, total size is compressed, reliability of the device is improved, and cost efficiency is increased. In addition, the use of magnetic vanes for propelling fluid improves motor efficiency. Further, the fluid flow is used to directly cool the pump/generator device, which reduces energy consumption.

Abstract: A multi-roll segment package (101) for plastic tape comprises a plurality of roll segments made up of concentrically disposed spiral winding groups (119) separated and defined by helical winding portions of tape (121) connecting the spiral winding groups on adjacent roll segments. The spiral winding groups of the end roll segments (111A), (111B) comprise at least 2.5 times the number of windings as the center roll segments (115A), (115B), (115C). The roll package features high wind density and good resistance from telescoping.

Abstract: A multi-roll segment package provides a method of winding a single length of plastic tape on a plurality of closely spaced roll segments. The roll segments are wound on a core with the length of tape continuous from the inner diameter of the first roll segment to the segment outer diameter of the last roll segment. Tape protectors made of a stiff web material enclose a portion of the lengths of tape between segment outer diameters to the next sequential segment inner diameter. The tape protectors stabilize the tape as it is turned or folded to the core of the next sequential roll segment position.

Abstract: An uninterruptible power supply is disclosed in which the backup energy source is connected to the power supply of the protected computer by means of a bi-directional power converter. This converter operates without sensing circuitry, relays, or switches, operating continuously when a load is present in either charging or discharging the backup energy source. This uninterruptible power supply can be placed within the available space of a functioning standard computer power supply enclosure, and may be configured so that it may be replaced during normal computer operation (i.e. it is "hot swappable"). Methods are described to interface the uninterruptible power supply to the computer, providing mutual control and communication. The device may be also used to power devices requiring external DC power, which are commonly found in association with computer operations.
