Patent number: 11962876Abstract: A plastic item, such as a beverage bottle, conveys two distinct digital watermarks, encoded using two distinct signaling protocols. A first, printed label watermark conveys a retailing payload, including a Global Trade Item Number (GTIN) used by a point-of-sale scanner in a retail store to identify and price the item when presented for checkout. A second, plastic texture watermark conveys a recycling payload, including data identifying the composition of the plastic. The use of two different signaling protocols assures that a point-of-sale scanner will not spend its limited time and computational resources working to decode the recycling watermark, which lacks the data needed for retail checkout. In some embodiments, a recycling apparatus makes advantageous use of both types of watermarks to identify the plastic composition of the item (e.g., relating GTIN to plastic type using an associated database), thereby increasing the fraction of items that are correctly identified for sorting and recycling.Type: GrantFiled: August 3, 2021Date of Patent: April 16, 2024Assignee: Digimarc CorporationInventors: Ravi K. Sharma, Tomas Filler, Vojtech Holub, Osama M. Alattar, Hugh L. Brunk, John D. Lord, Matthew M. Weaver, William Y. Conwell

Publication number: 20180248062Abstract: Disclosed are polyolefin copolymer films comprising alkoxysilane groups and a catalyst for crosslinking the alkoxysilane groups; wherein the crosslinking catalyst is a Lewis or Bronsted acid or base compound that has a relatively high melting point and therefore initiates the crosslinking essentially only at the lamination temperature, preferably at or above at least 50° C. Also disclosed are films wherein (i) the layer or layers comprising the alkoxysilane groups, including surface layer(s), comprise the crosslinking catalyst; or (ii) layer or layers comprising alkoxysilane groups do not contain crosslinking catalyst and have a facial surface in adhering contact with a layer of a thermoplastic polyolefin copolymer comprising the crosslinking catalyst; or (iii) there is a combination of layers (i) and (ii). Also disclosed are laminated glass structures and processes for their preparation that employ such films. The disclosed laminate structures include safety glass and photovoltaic modules.Type: ApplicationFiled: May 2, 2018Publication date: August 30, 2018Inventors: John D.

Publication number: 20090264584Abstract: An improved process for crosslinking a polyolefin polymer is described. The process involves grafting a silane material onto the polyolefin based polymer in the presence of a free radical generating initiator material and then hydrolyzing the silane material to form crosslinks. By using an effective molar ratio of silane material to free radical of 40 or greater in the grafting reaction, premature crosslinking is controlled and the grafted polymer can be shaped first and then crosslinked. In another aspect of the invention, the crosslinking process is improved by adding a catalyst for the hydrolysis catalyst to the surface of a shaped article made from the grafted polymer. Grafted polymer and articles made from the grafted polymer, particularly fibers, are also disclosed.Type: ApplicationFiled: June 10, 2009Publication date: October 22, 2009Applicant: Dow Global Technologies Inc.Inventors: Parvinder Walia, Rajen Patel, John Klier, John D.

Patent number: 6550771Abstract: A method of playing an object selection game (20), includes providing a set of objects containing a plurality of different individual objects, wherein each individual object has an order value in accordance with an ordering rule. A subset of the set of objects is dealt to a player in accordance with a dealing rule. A portion of the subset of objects is revealed to the player in accordance with a revealing rule. The player then selects any previously unselected object from the subset of objects in accordance with a selecting rule. After each selection, a terminating rule is used to test whether play shall stop, or whether additional objects are selected. The terminating rule stops play if objects are not selected in proper sequential order in accordance with the ordering rule. After play is stopped, a score is computed in accordance with a scoring rule. In preferred embodiments, the set of objects are playing cards, and a wager is placed on the outcome of the game.Type: GrantFiled: April 23, 2001Date of Patent: April 22, 2003Inventors: John D. Weaver, Janice L. Weaver, Gary A. Ramos

Patent number: 6324680Abstract: A method for synthesizing aggregate data types, in accordance with the present invention, includes representing aggregate data types in a control data flow graph, by representing aggregate objects as operand nodes, and operations on the aggregate objects as operation nodes. One-dimensional bit vectors are formed for the operand nodes, by recursively traversing through fields of the aggregate data type associated with the aggregate objects. Read and write operation nodes are formed in the control data flow graph for representing language constructs for accessing the aggregate objects. The control data flow graph is mapped onto hardware.Type: GrantFiled: August 30, 1999Date of Patent: November 27, 2001Assignee: International Business Machines CorporationInventors: Stephen Barnfield, Reinaldo A.
