  • Publication number: 20160063272
    Abstract: Virtual file management is disclosed. Managed content from multiple separate storage domains is organized into a virtual file system that maintains with respect to each of at least a subset of said separate storage domains information of storage domain specific file system primitives to perform primitive operations with respect to content stored in that storage domain. Policies are determined that apply to the managed content. Each policy indicates primitive operations permitted to be performed with respect to the managed content. Information comprising the virtual file system and the policies is provided to a client application on a mobile device. The client application is configured to provide access to the managed content in the virtual file system in a manner at least in part indicated in the policies, including by allowing the permitted primitive operations to be performed using said storage domain specific file system primitives.

  • Patent number: 9171292
    Abstract: A method, system, and computer program product for electronic delivery of regulated shareholder communications to registered electronic mail client accounts. A signed regulated shareholder communication electronic mail is generated by a proxy platform server computer and the electronic mail is transmitted to an electronic mail address inbox of a client computer. An active content associated with the shareholder communication is delivered by the proxy platform server computer when the shareholder communication is opened by a user on the client computer. The user is authenticated by the proxy platform server computer. A voting ballot is delivered by the platform server computer to the authenticated user's opened shareholder communication. The ballot votes submitted from the opened shareholder communication by the user are recorded in a proxy platform server computer voting database.

  • Patent number: 9149544
    Abstract: Non-aggregating resorbable calcium phosphosilicate nanoparticles (CPNPs) are bioconjugated to targeting molecules that are specific for particular cells. The CPNPs are stable particles at normal physiological pH. Chemotherapy and imaging agents may be integrally formed with the CPNPs so that they are compartmentalized within the CPNPs. In this manner, the agents are protected from interaction with the environment at normal physiological pH. However, once the CPNPs have been taken up, at intracellular pH, the CPNPs dissolve releasing the agent. Thus, chemotherapeutic or imaging agents are delivered to specific cells and permit the treatment and/or imaging of those cells. Use of the bioconjugated CPNPs both limits the amount of systemic exposure to the agent and delivers a higher concentration of the agent to the cell. The methods and principals of bioconjugating CPNPs are taught by examples of bioconjugation of targeting molecules for breast cancer, pancreatic cancer, and leukemia.

  • Publication number: 20150256151
    Abstract: The disclosure provides a circuit that includes an integrator that generates an integrated signal in response to a current signal. A comparator is coupled to the integrator and receives the integrated signal and a primary reference voltage signal. The comparator generates a feedback signal. A switched capacitor network is coupled across the integrator. The feedback signal activates the switched capacitor network.
