Patent number: 9483367Abstract: Various systems and methods for determining whether a distributed storage cluster is operating with a last failure domain are disclosed. The last failure domain is the only node with access to a latest copy of configuration data and an up-to-date copy of application data. In response to a determination that the distributed storage cluster is operating with the last failure domain, the method causes the last failure domain to copy one or more changed blocks of the up-to-date copy of the application data from one or more mirrored volumes to a recovery server for storage.Type: GrantFiled: June 27, 2014Date of Patent: November 1, 2016Assignee: Veritas Technologies LLCInventor: Ram Chandra Patil

Patent number: 7435877Abstract: Indian basil, Ocimum basilicum, belongs to the family of Lamiaceae. The essential oil of Indian basil extracted via hydro or steam distillation from the leaves or whole plants is used to flavor foods, dental and oral products, in fragrances, and in traditional rituals and medicines. Extracted essential oil has also been shown to contain biologically active constituents that are insecticidal, nematicidal, fungistatic or which have antimicrobial properties. The present invention relates to the development of an early, short duration, dwarf, high essential oil, methy chavicol and linalool yielding variety of Indian basil (Ocimum basilicum). Family—Lamiaceae) named as ‘CIM-SAUMYA’. This new variety of Indian basil was developed through open pollination in the germplasm followed by half-sib progeny selection and evaluation for the yield characters of selected population for 3 years in field conditions.Type: GrantFiled: August 6, 2004Date of Patent: October 14, 2008Assignee: Council of Scientific & Industrial ResearchInventors: Suman Preet Singh Khanuja, Raj Kishori Lal, Arun Kumar Agnihotri, Ajit Kumar Shasany, Ali Arif Naqvi, Samresh Dwivedi, Hari Om Misra, Om Prakesh Dhawan, Alok Kalra, Aparbal Singh, Janak Raj Bahl, Saudan Singh, Dharani Dhar Patra, Shilpi Agarwal, Mahendra Pandurang Darokar, Anil Kumar Gupta, Moti Lal Gupta, Ram Chandra
