Abstract:
Disclosed is a laminate of a polymer film and substrate wherein the polymer film has good heat seal and printing properties. The polymer film is prepared from an isotactic polypropylene or propylene-ethylene copolymer prepared using a metallocene copolymer.
Abstract:
An RFID tag that receives a calibration instruction from a reader can determine the basic backscatter period of the symbols to be backscattered. According to some embodiments, when the instruction includes a calibration feature that is to be divided by a divide ratio, the tag measures the duration of the feature in terms of numbers of internal pulses, resulting in a binary L-number. Then at least two versions of the L-number (PR1-number, PR2-number) are combined, so as to yield the effective result of the division alternately, even when the divide ratio is a non-integer. The backscatter period can then be determined from the BP-number and the period of the internal pulses.
Abstract:
RFID system components, such as readers and tags, communicate where the reader inventories a population of tags. The reader evaluates responses from tags by categorizing them in slots. As tags are inventoried, the number of slots based on a Q-parameter is reduced. The reader reduces the Q-parameter first in a first manner, then in a second manner where the second manner is different from the first manner. The first manner and the second manner may be different algorithms, different subroutines of an algorithm, or the same damping algorithm with different damping parameters.
Abstract:
RFID system components, such as readers and tags, communicate where the reader inventories a population of tags. The tags choose randomly one of a plurality of slots in response to each one of the values communicated by the reader and reply according to their chosen slot. The reader may initiate the inventorying by determining a Q-parameter value from a stored value and communicating the Q-parameter value to the tags. The reader may evaluate replies received from the tags in another plurality of tags, determine a second value from evaluating the second replies, and store the second value for future use.
Abstract:
A process is disclosed for communicating with individual tags in a population of tags having a binary tree organization, wherein each tag corresponds to a leaf node of the binary tree. The process includes singulating a predetermined leaf node and returning to a designated re-entry node associated with the predetermined leaf node after singulating.
Abstract:
A radio frequency identification tag is disclosed that is configured to transmit a signal modulated with one of more than two different subcarrier modulation frequencies such that the signal represents more than one binary bit as a single symbol.
Abstract:
Analog-valued floating-gate transistors are used as trimmable circuit components for modifying and/or controlling the gain, phase, offset, frequency response, current consumption, and/or transfer function of signal pathways in parallel and/or serial processing circuits in radio frequency, analog, or mixed-signal integrated circuits.
Abstract:
A thin film heater includes at least two open regions formed along each of two spaced-apart edges of the thin film material, which edges are parallel to two spaced-apart edges of the underlying substrate. The open regions expose areas of underlying substrate. When electrical power is coupled to the two spaced-apart edges of the thin film material, uniformity of the heat generated across the thin film material is enhanced. The substrate may be planar or curved, and the open regions in the thin film material may be removed from deposited thin film material, or may be formed by preventing deposition of thin film material in such regions.
Abstract:
A method and apparatus for producing increased protein chicken meal. Product is loaded into a cooking vat that is 40 feet long by 5 feet wide by 4 feet deep, with a system of moving chain conveyors and paddles. These conveyors move the product at a predetermined speed through oil maintained at a temperature of approximately 360.degree. to 380.degree. F. for the entire length of the vessel, and dumps the product at the opposite end of entry. Oil is circulated through the vat at a rate of approximately 680 to 860 gallons per minute (gpm) to allow for the rapid removal of fat and moisture from skin and meat in a continuous process. The volume of oil in the cooking vat is approximately 4,500 gallons.
Abstract:
A process for producing high impact polystyrene including feeding at least one vinyl aromatic monomer, an elastomer, and a free radical initiator to a first linear flow reactor to form a reaction mixture. Polymerizing the reaction mixture in the first linear flow reactor to a point below the point at which phase inversion occurs to produce a first polymerization mixture and feeding the first polymerization mixture from the first linear flow reactor to a second linear flow reactor. Polymerizing the reaction mixture in the second linear flow reactor to at least a phase inversion point of the mixture to produce a second polymerization mixture and feeding the second polymerization mixture from the second linear flow reactor to at least a third linear flow reactor for post-inversion polymerization of the second polymerization mixture. The product stream can have an ESCR value of at least 10% toughness retained with less than 10 wt % rubber content.
