Patent number: 11880303Abstract: One or more computing devices, systems, and/or methods for content cache invalidation using cache tags are provided. A first proxy hop may receive a request from a client device for a content object originating from a content source. A cache tagging script is executed to add a query parameter to the request to create a modified request. The query parameter specifies a cache tag version for the content object. The modified request is transmitted through one or more subsequent proxy hops to the content source to retrieve the content object. The content object, tagged with a cache tag specifying the cache tag version, is cached as a cached content object within a cache. The cache tag is associated with an expiration timestamp after which the cached content object is designated to be invalid.Type: GrantFiled: December 30, 2021Date of Patent: January 23, 2024Assignee: Yahoo Ad Tech LLCInventors: Peter Cheung, Shu Kit Chan

Patent number: 9989564Abstract: A circuit including over-current protection includes a voltage input, first and second switching transistors that are complementarily switched and that receive current from the voltage input, a first resistor, a first diode including a first anode and a first cathode, and a second diode including a second anode and a second cathode. The first anode and the second anode are connected to each other and are connected to the voltage input via the first resistor. The first cathode is connected to the first switching transistor and the second cathode is connected to the second switching transistor such that the connection of the first and second anodes provides an over-current signal that is related to the current in the first and second switching transistors.Type: GrantFiled: October 9, 2013Date of Patent: June 5, 2018Assignee: MURATA MANUFACTURING CO., LTD.Inventors: Atul Abhyankar, Peter Cheung

Patent number: 6541723Abstract: A rotary switch for an electrical appliance includes a housing adapted to receive a plurality of conductive wires, a plurality of conductive terminals fixedly mounted onto the housing, an actuation shaft rotatably mounted onto the housing, and a movable contact mounted onto the actuation shaft for selectively connecting two of the conductive terminals. The housing includes a base and a cover mounted onto the base. The cover includes a top surface, a bottom surface and a plurality of inwardly tapered guide walls. Each guide wall is shaped to define a slot into which an associated conductive wire can be securely retained in electrical isolation from the remainder of conductive wires. Each guide wall has a funnel-type configuration and includes a closed end and an open end, the slot being narrower at the closed end than at the open end.Type: GrantFiled: August 27, 2001Date of Patent: April 1, 2003Assignee: Tower Manufacturing CorporationInventors: Chepur P.

Patent number: 6003017Abstract: A PCI to SCSI host adapter circuit is provided for use with different types of host platforms. The host adapter includes logic and controller circuits, and a memory having multiple drivers and a bank switching instruction set stored therein. During initialization, the first driver is loaded into the host's memory if the host's processor is of a compatible type. Otherwise, the bank switching instruction set is loaded into the host's memory and interpreted by the host's processor. During interpretation, the bank switching instruction set causes the host's processor to signal the logic circuit to request that the controller circuit re-map another driver to the location of the first driver in the memory. After this bank switching has occurred, the selected driver is loaded into the host's memory, provided of course that the host's processor is of a compatible type. This process may be repeated until the appropriate code type is found or the host processor is not supported.Type: GrantFiled: May 30, 1997Date of Patent: December 14, 1999Assignee: Adaptec, Inc.Inventors: Anton B. Rang, Kin C. Doe, Gordon A. Minami, Daniel Olin Skeen, Tonghan Tee, James Lindeman, Peter Cheung
