  • Patent number: 11791734
    Abstract: A bidirectional power converter includes flyback converter units connected in parallel, each having a controller and adapted to accumulate power from a primary side during an ON time and to deliver the accumulated power to a secondary side during an OFF time, the primary and secondary sides being interchangeable as to the direction of power conversion, the controller operating at a boundary between discontinuous and continuous conduction modes and performing valley switching when switching from OFF to ON, one converter unit operating as a master wherein the controller is adapted to control the length of ON time in order to feedback-control an overall current output of the converter, and each other converter unit operating as a slave wherein the controller controls the length of ON time in order to feedback-control a phase delay of ON time of the slave relative to ON time of another converter unit.

  • Patent number: 9483367
    Abstract: 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.

  • Patent number: 7435877
    Abstract: 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.
