  • Patent number: 7462019
    Abstract: A pump for pumping sensitive fluids, such as blood, having no mechanical contact between the impeller and any other structure. The pump comprises a pump housing, an impeller disposed within the pump housing, a magnetic bearing system for supporting and stabilizing the impeller in five degrees of freedom, and a conformally shaped magnetically linked motor for rotating the impeller. The magnetic bearing system and motor advantageously comprise electromagnets and permanent magnets for stability and control of the impeller, and to reduce size, weight, and pump power consumption. Permanent and electromagnets are disposed on the pump housing and permanent magnets are disposed on the impeller such that by controlling electric current through the electromagnets on the housing, the magnetically suspended impeller functions as the rotor, and the housing as the stator of a D.C. motor.

  • 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.

  • Publication number: 20080244427
    Abstract: Control techniques support low latency display operations on thin client devices. In response to a request to render a page in a user interface, the control may distinguish fields that likely have immediately displayable content from fields that are unlikely to have immediately displayable content. The control may retrieve data for those fields that are likely to have immediately displayable content and render them in an initial page. Content for the fields that are unlikely to have immediately displayable content may be generated as a background process and may be rendered in supplemental page(s) as they become available. The control permits quick rendering of basic pages, which may include navigation functionality, and therefore promote early navigation operations or quick review of data which can be made immediately available.

  • Patent number: 7221764
    Abstract: Security key distribution techniques using key rollover strategies for wireless networks are described. A number of keys are generated, usually by an access point. The present invention allows a standard mode and a mixed mode. In standard mode, each device on the network supports automatic key updates. In mixed mode, one or more devices on the wireless network require fixed keys. In both modes, a predetermined number of keys are determined and communicated to client devices that are accessing the wireless network. The predetermined number is determined so that a client device can miss a certain number of authentication periods without losing communication with the wireless network. Preferably, transmit keys used by an access point are different than the transmit keys used by the client devices that support automatic key updates.
