Title: Cooling system with active debris separation
Inventor: RADKE DANIEL DEAN
IPC: B60K11/00
Filed: 2006-03-15
Granted: 2010-08-10
Abstract: A powered precleaner separates debris from atmospheric air through the use of a blower and a separation chamber. The chamber includes at least one inlet orifice and at least two additional orifices, including an outlet orifice and an exit orifice containing at least one heat exchanger. The blower blows air and debris along an inner surface of the separation chamber and out of the outlet orifice. The outlet orifice is sized to allow large debris to exit the chamber. Sufficient backpressure is created to cause a predetermined amount of precleaned air to flow through the exit orifice containing the heat exchanger. A screen may be added to trap larger light debris and prevent it from flowing to and plugging the heat exchanger.

Title: Systems and methods for mobility management in overlaid mobile communications systems
Inventor: DUTTA SANTANU
IPC: H04B7/185
Filed: 2004-09-23
Granted: 2013-04-30
Abstract: Communications of a mobile station with a satellite mobile communications system and a terrestrial mobile communications system are coordinated. The mobile station is registered with the terrestrial mobile communications system and, responsive to the registration of the mobile station with the terrestrial mobile communications system, the mobile station is concurrently registered with the satellite mobile communications system. The concurrent registration may include implicitly registering the mobile station with the satellite mobile communications system, e.g., by storing information identifying the mobile station in a location register of the satellite mobile communications system responsive to the registration of the mobile station with the terrestrial mobile communications system, and maintaining synchronization between the two registrations. Authentication tokens may be pre-generated for quick re-registration with a satellite mobile communications system.

Abstract: In displaying a map on a wireless communications device, a method is provided that resolves labelling of sharp curves. The method entails a determination of whether a curvature of a map element associated with the map feature exceeds a predetermined threshold (e.g. whether a rate of change in slope of a path or the change in angular orientation of each successive character in the label exceeds a threshold that is a function of zoom level. If the curvature exceeds the threshold, the label is rendered on the map in a new map location that avoids the map location where the curvature exceeds the threshold.

Abstract: Poly(propylene fumarate) is copolymerized with poly(caprolactone) diol to produce a block copolymer of poly(propylene fumarate) and poly(caprolactone).  The biocompatible and bioresorbable block copolymer of poly(propylene fumarate) and poly(caprolactone) is useful in the fabrication of injectable and in~ situ hardening scaffolds for tissue and/or skeletal reconstruction.  The block copolymer can be crosslinked by redox or photo-initiation, with or without an additional crosslinker. Thus, the copolymer is both self-crosslinkable (without the use of any crosslinkers) and photocrosslinkable (in the presence of photons such as UV light).

Abstract: A leash assembly designed to attach at least one waste holding device, such as a plastic bag, in such a manner that the plastic bag is able to swivel about and not get tangled as the dog moves from side to side. This eliminates the need of the person walking the dog to constantly move the leash from one hand to the other hand in order to prevent the waste bag from getting tangled. In other words, as the dog move in different directions the waste bag holding device is able to adjust its' position by swiveling about the device attached to the leash allowing the walker to have their hands free. The swivel can also be adapted to hold other items such as keys, extra bags for dog cleanup and hand wipes. All of these items would also be able to swivel about the device. The present invention eliminates the need for the person walking the dog from carrying the waste bag and switching the bag from hand to hand as the dog moves from side to side until a waste receptacle is reached that the waste can be disposed of properly.
