Abstract: The present invention relates to medical devices and particularly to a medication delivery device for self-injection of a medication, or for healthcare professionals to administer a medication. In one embodiment, a medication delivery device utilizes a source of gas pressure to deploy a needle, deliver a desired amount of medication through the needle, and retract the needle for disposal. Fluid flow paths from the source of gas pressure communicate the gas pressure to the needle and to the medication in order to accomplish these steps. In one embodiment, a valve is positioned to open and close the flow of the pressurized gas to the needle and the flow of the medication to the needle, so that the valve can be operated to deploy the needle and deliver the medication through the needle when the user is ready for the injection. The valve can also be operated to retract the needle when the dose is complete.

Abstract: A method, system and apparatus for efficient storage of small files in a segment-based deduplication scheme by allocating multiple small files to a single data segment is provided. A mechanism for distinguishing between large files (e.g., files that are on the order of the size of a segment or larger) and smaller files, and starting a new segment at the beginning of a large file is also provided. A file attribute-based system for determining an identity of a small file at which to begin a new segment and then allocating subsequent small files to that segment and contiguous segments until a next small file having an appropriate attribute subsequently is encountered to begin a new segment is further provided. In one aspect of the present invention a filename hash is used for file attribute analysis to determine when a new segment should begin.

Abstract: A collapsible inhalation device for use with a metered dose inhaler (MDI) dispenser includes an outlet end member, an inlet end member and a tubular, pliable, collapsible sleeve member attached at either end to the inlet and outlet members. The outlet end member includes a mouthpiece. The inlet end member includes an inlet port and an MDI dispenser mount structure configured to receive and engage the MDI dispenser. The inhalation device is positionable in each of an open position, wherein the sleeve member defines a chamber, and a closed position, wherein the sleeve member is collapsed and enveloped by the outlet end member and the inlet end member.

Abstract: The present invention provides a sample collection device for determining that an adequate amount of sample is collected, the sample collection device including a sample collection member for collecting a fluid sample and at least one electrode, the at least one electrode being in liquid communication with the sample collection member and including a processor. In one embodiment, the sample collection member includes a groove structure, wherein at least one electrode is located on each side of the groove.

Abstract: Detection and proper deduplication of a re-started data stream in a segmentation analysis-based deduplication system are provided by retaining information about a previous data stream and using that information when performing segmentation of the re-started data stream. Information such as a segment size associated with a last data object received in the previous data stream and a record of how much data was present in the last segment associated with the previous data stream is retained. The retained segment size information is used to set a first data object segment size of the re-started data stream, and the size of last segment information is used to determine how much information should be put in the first segment associated with the re-started data stream in order to maintain proper alignment of the remainder of the segments for the first data object in the re-started data stream for deduplication.

Abstract: The present invention is directed to methods and apparatus for detection of one or more analytes. Analytes include agents or components of infectious agents such as pathogenic virus, as well as enzymes, proteins and biomarkers.

Abstract: A transducer assembly may include a first transducer having a first front volume, a first back volume and a first port acoustically coupled to the first front volume; and a second transducer having a second front volume, a second back volume and second port acoustically coupled to the second front volume. The first front volume and the second front volume are acoustically coupled to increase the effective back volume of both the first transducer and the second transducer. An optional signal processing circuit may be used to control the output of the first transducer based upon a signal received from the second transducer.
