Patent number: 11965356Abstract: In one form, a cylindrical lockset includes a chassis including a pair of hubs, a pair of drive tubes, a retractor, and a lock control assembly. The lock control assembly has a locked state and an unlocked state. The lock control assembly also has a plurality of movable elements, each having a locking position and an unlocking position. One of the hubs includes a guide channel, and a slider is movably seated in the guide channel. One of the movable elements is associated with the slider, and is configured to move the slider between a lock-indicating position and an unlock-indicating position.Type: GrantFiled: April 14, 2022Date of Patent: April 23, 2024Assignee: Schlage Lock Company LLCInventors: Smitha Basavaraju, Kenton H.

Patent number: 11920379Abstract: An exemplary product line system includes a common platform and a plurality of component families, each of which includes a plurality of interchangeable component species configured for use with the common platform. The common platform includes an inside drive assembly and a chassis assembly including a chassis and an outside drive assembly. A lockset assembled from the system includes the common platform and a plurality of modular components. Each of the modular components corresponds to a respective one of the component families, and is provided as a selected species of the corresponding component family. The lockset has a function defined by the set of component species installed to the lockset. The function of the lockset can be changed by altering the set of component species installed to the lockset without disassembling the chassis assembly.Type: GrantFiled: August 3, 2021Date of Patent: March 5, 2024Assignee: Schlage Lock Company LLCInventors: Kenton H. Barker, Subbiah Gopalakrishnan, David J. Hurlbert, Kasey Wachtendorf, Snehil Solanki, Dilip Bangaru, Austin M. Roup, Rakesh Murali

Patent number: 9367820Abstract: In one embodiment, an indication that a decision has been requested, selected, or applied with respect to one or more users may be obtained. After the indication that a decision that has been requested, selected, or applied is obtained, a value function may be updated, where the value function approximates an expected reward associated with the one or more users over time since the decision has been requested, selected, or applied with respect to the one or more users. The value function may be updated by performing or providing one or more updates to the value function, where a time at which each of the one or more updates is performed or provided is independent of activity of the one or more users.Type: GrantFiled: December 16, 2014Date of Patent: June 14, 2016Assignee: NICE SYSTEMS TECHNOLOGIES UK LIMITEDInventors: Leonard Michael Newnham, Jason Derek McFall, David J Barker, David Silver

Patent number: 8924318Abstract: In one embodiment, an indication of a Decision Request or an Update Request may be received, where the Update Request is activated independent of user activity. A user state pertaining to at least one user may be received, obtained, accessed or constructed. For the Decision Request, one or more actions may be scored according to one or more value functions associated with a computing device, a policy associated with the computing device may be applied to identify one of the scored actions as a decision, and an indication of the decision may be provided or applied. For the Update Request, the one or more value functions and/or the policy may be updated. An indication of updates to the one or more value functions and/or an indication of updates to the policy may be provided.Type: GrantFiled: September 28, 2012Date of Patent: December 30, 2014Assignee: Nice Systems Technologies UK LimitedInventors: Leonard Michael Newnham, Jason Derek McFall, David J Barker, David Silver

Patent number: 5198162Abstract: A microporous polymeric film of high porosity comprises a halopolymer in which the repeating units are --(C.sub.n H.sub.2n)-- and --(C.sub.m X.sub.2m)-- in which each X independently represents fluorine or chlorine and the values of n and m are greater than one and less than six. The film is the result of firstly melt processing a mixture of the halopolymer, more than 150 parts by weight of an extractable salt and not more than 80 parts by weight of an extractable polymer per 100 parts by weight of the halopolymer, the extractable polymer not being completely and homogeneously mixed with the halopolymer and being less viscous than the halopolymer when both are molten so that the surfaces of the film resulting from melt processing are rich in the extractible polymer, and secondly extracting at least some of the extractable salt to render the film porous and extracting at least some of said polymer to impart surface porosity to the film.Type: GrantFiled: June 13, 1989Date of Patent: March 30, 1993Assignee: Scimat LimitedInventors: George B. Park, John A. Cook, Mike G. L. Dorling, David J. Barker, Robert H. McLoughlin

Patent number: 4707388Abstract: A dimensionally recoverable article, preferably a heat-recoverable article, has on at least part of a surface thereof an adhesive composition that will cure by reaction of a plurality of mutually reactive components. The components are in the form of particles which are mixed together and which will fuse when heated. Preferred adhesives are based on combinations of an epoxy with a polyamide, carboxylic acid, phenolic resin or blocked isocyanate curing agent.The particulate adhesives show a synergistic increase in rate and/or level of cure when used in conjunction with a recoverable article.Type: GrantFiled: January 23, 1986Date of Patent: November 17, 1987Assignee: Raychem LimitedInventors: George B. Park, David J. Barker
