Patent number: 11693035Abstract: A current sense system may include a relay, a load conductor, and an integrator sub-circuit. Current may be provided to an electrical load via the load conductor and a latch of the relay. The current carried via the load conductor may induce a sense voltage in a coil of the relay. Based on the sense voltage induced in the relay coil, the integrator sub-circuit may determine a load sense voltage that indicates a level of the current carried via the load conductor. In some implementations, a current indication module may provide an indicator signal based on the load sense voltage. In addition, the indicator signal may be provided to additional components or devices, such as a relay controller configured to activate the latch. In some implementations, the relay controller may be configured to open the latch based on the current level described by the indicator signal.Type: GrantFiled: August 10, 2020Date of Patent: July 4, 2023Assignee: ABL IP Holding LLCInventors: David J. Long, Miroslaw Grotkowski, Richard Lee Westrick, Jr.

Patent number: 8745017Abstract: Techniques are provided for performing transaction-aware caching of metadata in an electronic file system. A mechanism is described for providing transaction-aware caching that uses a cache hierarchy, where the cache hierarchy includes uncommitted caches associated with sessions in an application and a committed cache that is shared among the sessions in that application. Techniques are described for caching document metadata, access control metadata and folder path metadata. Also described is a technique for using negative cache entries to avoid unnecessary communications with a server when applications repeatedly request non-existent data.Type: GrantFiled: March 14, 2008Date of Patent: June 3, 2014Assignee: Oracle International CorporationInventors: David J. Long, David B. Pitfield

Patent number: 8529319Abstract: Embodiments of the present invention resolve the safety and product management issues associated with conventional abrasive wheel bushings by, for example, reducing the opportunity for improperly mounting an abrasive wheel without the appropriate reducing bushing, simplifying the purchasing process, and/or reserving valuable SKU space for primary products. The abrasive wheel itself can be tailored to any number of purposes, such as grinding, cutting, and polishing. The bushing described herein can be used with any such abrasive wheels. The techniques could readily be extended to any arbor-based products that use reduction bushings or similar schemes.Type: GrantFiled: February 8, 2008Date of Patent: September 10, 2013Assignees: Saint-Gobain Abrasives, Inc., Saint-Gobain AbrasifsInventors: Deborah Anne Gaspich, David J.

Patent number: 7725878Abstract: A method and apparatus for associating methods or attributes on a per-instance basis is provided. One technique for providing “per-instance attributes” involves properties and property bundles. A second technique for providing “per-instance attributes” involves categories wherein the instance can be thought of as being “placed” into one or more categories. A technique for providing “per-instance methods” involves policies. In any of these techniques, providing per-instance properties may be used in any of the following ways: (1) different instances of the same class are associated with different properties where the properties are not in the class; and (2) two instances of two different classes are associated with the same property where the property is not in either of the two classes.Type: GrantFiled: December 28, 2001Date of Patent: May 25, 2010Assignee: Oracle International CorporationInventors: David J.
