  • Patent number: 12521720
    Abstract: Infectious diseases have been sources of large-scale epidemics and pandemics resulting in millions of casualties worldwide. Detection of these biological agents normally involves several lab processes including sample preparation, nucleic acid separation and amplification, and diagnostic analysis. These steps, either performed manually or automated by high-throughput machinery, are tedious, expensive, and highly susceptible to cross-contamination. The present system is an integrated lab-on-a-device designed, developed, and tested in compatibility with a mechanical fixture for sample-to-answer biological analysis of infectious diseases.

  • Patent number: 10819709
    Abstract: An organization that wishes its messages to be secure (the “communicating organization”) uses services of a secure communications infrastructure to securely exchange communications among its users. The secure communications infrastructure allows granting to third-party applications the permission to act on behalf of the users when using the secure communications infrastructure. This delegation may be accomplished at a very granular level, specifying the particular applications that are authorized to act on behalf of a user, the particular operations that those applications are authorized to perform, and/or in which contexts the applications may perform the operations. An agent component acts as an intermediary between third-party applications and the core of the secure communications infrastructure. This permits the third-party application to take actions on behalf of the user, while also preventing the third-party applications from obtaining the security-specific data that could lead to a breach of security.

  • Patent number: 8572159
    Abstract: Machine-readable media, methods, apparatus and system are described. In some embodiments, a client platform may determine that an input/output operation related to a hardware device may happen in a virtual machine of the client platform and request a server platform via the network to handle the input/output operation related to the hardware. The server platform may receive the request from the client platform through the network; and identify a software device from a plurality of software devices in the server platform to handle the request, wherein the identified software device corresponds to the hardware device related to the input/output operation.

  • Publication number: 20090106754
    Abstract: Methods, system and machine-readable medium are described to handle a device related operation in a virtualization environment. In some embodiment, a kernel component of a virtual machine monitor may determine that a device related operation happens in a virtual machine through a operation transition from the virtual machine to the kernel component; and may determine whether the device related operation can be handled by a first virtual hardware device installed inside of the kernel component of the virtual machine monitor. In other embodiment, the kernel components may initiate an interrupt by the first virtual hardware device; and inject the interrupt from the first virtual hardware device to the virtual machine through another operation transition from the kernel component to the virtual machine.

  • Publication number: 20070242261
    Abstract: The present invention includes an apparatus for aerosol measurement having a high concentration of particles the apparatus comprising a diluter for diluting the concentration of particles in a sample aerosol stream to form a diluted aerosol stream, and a sensor for detecting the particles in the diluted aerosol stream by vapor condensation, droplet growth and optical detection. Such apparatus may be housed in a common housing along with the electronics for operating the apparatus and components such as pumps and filters that may be necessary. The diluter includes an input for an aerosol stream having an initial particle concentration, and a dilution stream. The aerosol stream and the dilution stream flow through a restriction which is sized such that turbulent flow is created so that the dilution stream and the aerosol stream are mixed to produce a diluted aerosol stream.

  • Publication number: 20070106984
    Abstract: An application suite installation framework comprises an application suite installer program, an installation configuration file, and the program files that comprise the software applications. The framework allows a user to specify the software applications that are to be installed on the user's computer system, and, based on the user's input, creates the installation configuration file. The installation configuration file contains an entry for each software application which was specified by the user. The application suite installer program reads the installation configuration file to determine the installation options (i.e., the software applications) to display, and displays to the user a list of the software applications that may be installed.
