Patent number: 11663143Abstract: A server includes a data cache for storing data objects requested by mobile devices, desktop devices, and server devices, each of which may execute a different configuration of an application. When a cache miss occurs, the cache may begin loading portions of a requested data object from various data sources. The cache itself may be divided into multiple partitions, and each of the partitions may be assigned to a specific attribute, such as an application configuration. Portions of the data object may be loaded into corresponding cache partitions based on the attributes of each. Although part of a single cache, each of the partitions may be independently assigned different cache replacement policies. Performance metrics for each of the partitions may be monitored and used to update the cache replacement policy for each partition at runtime without interrupting response traffic.Type: GrantFiled: February 21, 2020Date of Patent: May 30, 2023Assignee: ORACLE INTERNATIONAL CORPORATIONInventors: Yuvaraj Chandrasekaran, Lawrence Lindsey, Mihir Kumar Das, Santosh Kumar Kotikalapudi

Patent number: 11625325Abstract: A server includes a data cache for storing data objects requested by users logged in under different user roles. Different user roles may have different permissions to access individual fields within a data object. When a cache miss occurs, the cache may begin loading portions of a requested data object from various data sources. Instead of waiting for the entire object to load to change the object state to “valid,” the cache may incrementally update the state through various levels of validity based on the user role of the request. When a portion of the data object used by a low-level user role is received, the object state can be upgraded to be valid for that user role while data for higher-level user roles continues to load. The portion of the data object can then be sent to the low-level user roles without waiting for the rest of the data object to load.Type: GrantFiled: June 1, 2020Date of Patent: April 11, 2023Assignee: ORACLE INTERNATIONAL CORPORATIONInventors: Yuvaraj Chandrasekaran, Mihir Kumar Das, Pushpander Singh, Lawrence Lindsey

Publication number: 20180294123Abstract: An electrical switching apparatus is for an electrical system. The electrical system has an enclosure and an electrical apparatus coupled to the enclosure. The electrical switching apparatus includes a pair of separable contacts electrically connected to the electrical apparatus, an operating handle for opening and closing the pair of separable contacts, and a support assembly having a cover and an elongated extension extending from proximate the cover to proximate the operating handle. The cover at least partially encloses the pair of separable contacts. The elongated extension is structured to be coupled to the enclosure.Type: ApplicationFiled: April 11, 2017Publication date: October 11, 2018Applicant: COOPER TECHNOLOGIES COMPANYInventors: RICHARD JAMES SMITH, MOHANESH MADHUKAR PATOLE, AMOL NIVRATIRAO JADHAV, RANDAL VERNON MALLIET, BRYAN JOSEPH LOEB, KURT LAWRENCE LINDSEY, ARTHUR THOMAS DAVIES

Patent number: 8153916Abstract: A transformer switch, such as a dual voltage switch or a tap changer. The switch includes a cover, a housing, and a rotor sandwiched between the cover and the housing. The cover and housing are molded from a non-conductive plastic. An interior space of the cover includes at least one pocket within which stationary contacts are disposed. Each stationary contact is electrically coupled to one or more windings of a transformer. The rotor extends within a channel of the housings from a top of the transformer switch to an interior surface of the cover. The interior surface includes a protrusion about which the rotor and at least one movable contact coupled thereto can rotate. The movable contact is configured to be selectively electrically coupled to at least one of the stationary contacts. For example, different stationary contact-movable contact pairs can correspond to different voltages of the transformer.Type: GrantFiled: August 14, 2008Date of Patent: April 10, 2012Assignee: Cooper Technologies CompanyInventors: Kurt Lawrence Lindsey, Randal Vernon Malliet, Rick Alan Rachwal, Patrick Harold Pride

Patent number: 8013263Abstract: A transformer switch, such as a multi-deck tap changer, includes an assembly with a first housing coupled to a first cover. The first cover holds at least a first stationary electric contact. A second housing is formed integrally with the first cover, and is coupled to a second cover, the second cover holding at least a second stationary electric contact. The first housing and first cover together define a first interior volume within which the first stationary electric contact is disposed. The second cover and the second housing together define a second interior volume within which the second stationary electric contact is disposed. Each housing-cover coupled pair includes an interior rotor rotatable relative to the stationary electric contact in the cover of the pair. At least one movable contact is coupled to each rotor. The covers and housings can be molded from a non-conductive plastic.Type: GrantFiled: June 3, 2009Date of Patent: September 6, 2011Assignee: Cooper Technologies CompanyInventor: Kurt Lawrence Lindsey

Patent number: 8004377Abstract: A fault interrupter and load break switch includes a trip assembly configured to automatically open a transformer circuit electrically coupled to stationary contacts of the switch upon the occurrence of a fault condition. The fault condition causes a Curie metal element electrically coupled to at least one of the stationary contacts to release a magnetic latch. The release causes a trip rotor of the trip assembly to rotate a rotor assembly. This rotation causes ends of a movable contact of the rotor assembly to electrically disengage the stationary contacts, thereby opening the circuit. The switch also includes a handle for manually opening and closing the electrical circuit in fault and non-fault conditions. Actuation of the handle coupled to the rotor assembly via a spring-loaded rotor causes the movable contact ends to selectively engage or disengage the stationary contacts.Type: GrantFiled: May 8, 2008Date of Patent: August 23, 2011Assignee: Cooper Technologies CompanyInventors: Nicholas Brusky, Kurt Lawrence Lindsey
