20100282894 | Antenna pointing bias estimation using radar imaging - A system for estimating an antenna boresight direction. The novel system includes a first circuit for receiving a Doppler measurement and a line-of-sight direction measurement corresponding with the Doppler measurement, and a processor adapted to search for an estimated boresight direction that minimizes a Doppler error between the Doppler measurement and a calculated Doppler calculated from the estimated boresight direction and the line-of-sight direction measurement. The line-of-sight direction measurement is measured relative to the true antenna boresight, and the calculated Doppler is the Doppler calculated for a direction found by applying the line-of-sight direction measurement to the estimated boresight direction. In a preferred embodiment, the first circuit receives a Doppler measurement and a line-of-sight direction measurement from each of a plurality of pixels, and the processor searches for an estimated boresight direction that minimizes a sum of squares of Doppler errors for each of the pixels. | 11-11-2010 |

20100249293 | POLYESTER BLENDS - Polyester blends comprising (1) polyesters prepared from terephthalic acid, 100 to 5 mol % of 2,2,4,4-tetramethyl-1,3-cyclobutanediol, and 0 to 95 mol % 1,4-cyclohexanedimethanol and (b) polyesters prepared from terephthalic acid and alkylene glycol. The blends may also contain an impact modifier and a phosphorous stabilizer. These blends can have a combination of thermal stability and toughness—making the materials useful in engineering molding plastics, packaging, films, and fibers. | 09-30-2010 |
20110086212 | POLYESTER COMPOSITIONS FOR MOLDING CLEAR PARTS - This invention relates to certain poly(1,4-cyclohexylenedimethylene terephthalate) copolyesters which are useful for the preparation of clear and tough thick wall molded parts, produced at good cycle times. The copolyesters can be molded into desired shapes such as cosmetic jars, fragrance caps, tool handles, and toothbrushes. These molded articles can have thick or thin walls and may be molded in a two shot molding process. The copolyesters also have good flow and reduced cycle times. | 04-14-2011 |

20090017168 | FOOD COMPOSITIONS WITH DOUGH BINDERS AND METHODS RELATED THERETO - The present invention provides food compositions useful as ready-to-eat cereals, snacks, and toppings, and processes for making them. Particularly, the present invention provides food compositions with crisp texture, reduced fat, and surprising bowl life when used as a ready-to-eat cereal. The present food compositions are also an improvement over previous toppings or snacks, in that the present compositions comprise fewer “fines” or individual grains. Moreover, since the present compositions comprise a dough binder rather than a sugar binder, nutritional supplementation is possible, such as the addition of fiber. Efficient processes are also provided for making the present food compositions. Superior intermediates and end products are therefore also provided. | 01-15-2009 |
20090081335 | CRISP, FILLED FOODS AND METHODS RELATED THERETO - The present invention provides crisp filled foods, intermediates, and processes for making them. Particularly, the present invention provides crisp crackers, pretzels, breadsticks, cookies and the like with creamy and lubricious filling. Efficient processes are also provided for making such crisp filled foods, wherein dough is baked, fried or similarly heated in the presence of a specially-formulated powder so as to ultimately result in a lubricious filling and a crisp exterior. Superior intermediates and end products are therefore also provided. The foods surprisingly retain their crisp exterior and lubricious interior for an extended time span when packaged and stored under commercial conditions. | 03-26-2009 |
20140287101 | Rotary Molded Shaped Crunchy Granola Food Products and Methods of Making Same - Disclosed are nonlimiting embodiments comprising a novel process for forming and shaping crunchy granola food products. The process comprises using rotary molding processes to form and shape a granola mass into a variety of desired shapes. The granola mass is able to be rotary molded as a result of use of a unique binder composition that comprises at least one pre-gelatinized starch in the binder composition. The pre-gelatinized starch enables the binder viscosity to increase and increases the tackiness of the granola mass such that it can be formed by a rotary molder and such that it releases from the mold as a unitary piece of shaped and formed granola food product. | 09-25-2014 |
