Patent number: 11489479Abstract: Methods and apparatuses for detecting an open load condition for a load. The load is coupled to a power source at a high side and to a ground at a low side through at least one switch, the load has a first end and a second end, a first voltage at the first end is kept constant. A switch is controlled by a PWM signal. After the switch is turned off by the PWM signal, the voltage associated with the second end of the load is measured. In one embodiment, a change of the second voltage during a predefined delay is compared with a predefined voltage threshold. In another embodiment, the time it takes for the change of the second voltage to reach a predefined voltage threshold is compared with a predefined time threshold.Type: GrantFiled: August 3, 2017Date of Patent: November 1, 2022Assignee: Cummins Inc.Inventors: Subramanya Bhat, Santosh Shankar Koli, Shashi Kanth Belde, Abu Musa

Patent number: 10678832Abstract: The subject technology provides a search index that maps clusters of semantically similar phrases to documents that contain any one of the phrases of the respective cluster. The subject technology may identify the phrases from a set of documents, such as a document corpus, where each of the documents is associated with a document identifier. The subject technology may generate the clusters of semantically similar phrases from the identified phrases, where each of the generated clusters is assigned a cluster identifier. The subject technology generates an index that stores each respective cluster identifier of each respective cluster in association with each document identifier of each of the documents that includes at least one of the phrases contained in the respective cluster. Further, the subject technology stores the index in a memory such that the index may be subsequently utilized to identify documents that match a search query.Type: GrantFiled: September 29, 2017Date of Patent: June 9, 2020Assignee: Apple Inc.Inventors: Saravana Kumar Siva Kumaran, Jiayan Gan, Mohamed Temraz, Santosh Shankar

Patent number: 7734878Abstract: Systems, methods, apparatus and software can make use of separated I/O processors and strategy processors (implemented in hardware and/or software) to perform virtual device I/O operations. I/O processors operating on cluster nodes, storage appliance ports, or other devices can receive I/O operation requests directed to virtual devices, e.g., volumes or virtual logical units. Information about the request is forwarded to a strategy processor, operating independently or as part of larger volume management software where corresponding physical device I/O operations are determined. The physical device I/O operations can include additional information about the operations, e.g., tag information and summary information, for use in processing the virtual device I/O request. The physical device I/O operations are sent back to the I/O processor which executes the operations and/or passes the operation on to the appropriate storage device.Type: GrantFiled: April 10, 2007Date of Patent: June 8, 2010Assignee: Symantec Operating CorporationInventors: Gopal Sharma, Oleg Kiselev, Santosh Shankar Rao
