Title: Foamed isocyanate-based polymer
Inventor: FARKAS PAUL
IPC: C08G18/64
Filed: 2008-03-03
Abstract: There is described a novoel isocyanate-based polymer foam. The isocyanate- based polymer foam is derived from a reaction mixture comprising: (a) an isocyanate; (b) a mixture of active hydrogen-containing compounds; and (c) a blowing agent. The mixture of active hydrogen-containing compounds comprises: (i) a bio-based polyol having an OH functionality of greater than about 2.0, an OH number in the range of from about 90 to about 200 and a molecular weight (Mn) of at least about 1100, and (ii) a petroleum-based active hydrogen-containg compound. It has been surprisingly and unexpectedly discovered that relatively high amounts (compared to the prior art) of such a bio-based polyol may be incorporated into an isocyanate-based polymer foam while maintaining a desirable balance of properties in the foam. Use of such a bio- based polyol (as a single bio-based polyol or a mixture of bio-based polyols) allows for displacement of at least a portion of petroleum-based polyols conventionally used in the production of isocyanate-based polymer foam while maintaining a desirable balance of properties in the foam, particularly molded foam. The addition benefit is that such displacement is of a component that this non-renewable and relatively more expensive than bio-based polyols.

Abstract: A three wheeled scooter comprises a chassis having forward and aft ends with a front wheel non-pivotally mounted to the forward end and a pair of rear wheels coaxially mounted to the aft end. The chassis defines a longitudinal axis and includes a support assembly and a handle assembly extending upwardly from the support assembly. The rear wheels are configured to be angularly yawable relative to the longitudinal axis between a neutral position and a yawed position. Steering of the scooter is thereby effectuated by angular yawing of the rear wheels relative to the longitudinal axis such as by asymmetric loading of one of opposing sides of the support assembly.

Title: A method for generating a clear frame from an image frame containing a subject disposed before a backing of nonuniform illumination
Inventor: VLAHOS PAUL ERNEST
IPC: G06K9/40
Filed: 2008-03-20
Abstract: A method for extracting a clear frame from an image frame containing at least one or more subjects disposed before a backing, whose color and luminance vary smoothly from one backing area to another. The method replaces a subject's pixel signal levels with backing pixel signal levels. The method selects a known backing pixel and compares the RGB signal levels of an adjacent pixel with the RGB signal levels of the known backing pixel and identifies the adjacent pixel as a backing pixel when its RGB signal levels are each within an assigned tolerance of the RGB signal levels of the known backing pixel. This comparison is performed on all known backing pixels with unidentified adjacent pixels until all pixels in the image frame have been examined and all backing pixels identified. The method then replaces the RGB signal levels of the at least one subject's pixels with the RGB signal levels of backing pixels located at opposite edges of said at least one subjects by at least one of interpolation and or extrapolation across the at least one subject thereby removing said at least one subject to leave a clear frame.

IPC: H04L7/04
Filed: 2008-11-03
Abstract: A system to distribute accurate time and/or frequency over a network utilizing signals of opportunity transmitted by one or more local transmitters with known loca tions, the system includes a base receiver with a clock synchronized to a reference time scale such as GNSS or UTC time that saves a series of samples of the signals of opportunity and time tags the series with a calculated time of broadcast. A  remote receiver saves samples of the signals of opportunity and correlates the series with the saved samples. The remote receiver calculates a time of transmission of saved sam ples that correspond to the series, determines a time offset as a difference in the time of broadcast calculated at the remote receiver and the time of broadcast calculated at the base receiver, and determines the time offset with respect to the base receiver. The base receiver further or instead phase locks to the signal opportunity and at prede termined intervals determines phase measurements of the integrated carrier frequency of the signal of opportunity and provides the phase information to the remote receiver. The remote receiver, which is also phase locked to the same signal of opportunity, uses the phase measurement information to frequency lock its clock to the base re ceiver clock by determining a frequency error based on the rate of change of phase measurements made at the base receiver and the remote receiver.
