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:
The present invention provides systems, methods, computer program products, and combinations and subcombinations thereof for filtering received messages. The invention includes a client system having filtering logic, a statistical classifier module, and a classifier database. The classifier module is automatically trained, without manual intervention, when the score generated by the classifier for a received message is inconsistent with a user-defined authoritative status indication. In addition, the classifier module is initialized using user-identified messages in a ratio representative of the ratio of non-spam to spam messages received by the user.

Abstract:
A method of bonding an antimicrobial cationic polyelectrolyte to the surface of a substrate is described, wherein the antimicrobial thus attached to the substrate provides the substrate with antimicrobial properties, and at least a portion of the bonded antimicrobial is substantially non-leachable during normal conditions of use and storage. A method of manufacturing an antimicrobial material is described which comprises exposure of the substrate to a solution of antimicrobial cationic polyelectrolyte, followed by drying the exposed substrate thoroughly to impart a non-leaching property to at least a portion of the antimicrobial cationic polyelectrolytes.
Abstract:
The present invention provides a spring probe array for use in a semiconductor test fixture wherein the spring probes provide electrical continuity between a device under test and a test system. The array includes a spring probe retaining device with sockets for supporting spring probes. Fixed within the retaining device are a plurality of signal spring probes and a plurality of ground spring probes. A grounding board is fixed internal and captive to the spring probe retaining device and provides a common grounding connection between coaxial spring probes and adjacent non-coaxial spring probes in the spring probe retaining device.
Abstract:
Systems, devices and methods for treating internal tissue defects, such as septal defects, are provided. An exemplary method of treating an internal tissue defect, specifically a method of closing a patent foramen ovale (PFO), can include passing a closure element from a right atrium through a septal wall in a first location and into the left atrium. A capture device, which can be configured as a snare-like device, can be used to capture the closure element in the left atrium and pull the closure element back through the septal wall in a different, second location, such that the closure element is routed over the PFO. The closure element can then be anchored and/or locked against the septal wall such that the PFO is at least partially closed.
Abstract:
A sensor for measuring moisture content of a substrate, comprising: a coplanar waveguide; a directional coupler having a pair of generally parallel first and second strips defining a coupling gap therebetween; and a high frequency signal generator electrically coupled to said first strip and operable to couple power to said second strip with the substrate placed across said coupling gap to thereby generate a coupled power signal in said second strip having an amplitude related to moisture content of the substrate.
Abstract:
A ventilation system includes a ventilation tile. The ventilation tile has a substantially circular opening to allow air to flow through the ventilation tile and a collapsible damper operable to collapse and expand to alter the size of the substantially circular opening in the ventilation tile and thereby variably restrict air flow through the substantially circular opening.
Abstract:
A lighting system adapted to mount on a motorcycle or bicycle helmet. The lighting system includes a one or more accelerometers coupled to the helmet and a processor adapted to process the signals from the accelerometers. The accelerometers may be mounted to the helmet, or the motorcycle or bicycle. The lighting system further includes a light mounted on the helmet that is responsive to the processed signal such that the light illuminates as result of a deceleration force. The system may also include filtering software to remove helmet motion artifact and other noise from the signal. Remote wheel speed indicators may also be used in conjunction with or in place of the accelerometers. Mounting tabs may also be included to releasably attach the lighting unit to the helmet.
Abstract:
Various embodiments of a computer-implemented method, system and computer program product backup a dataset. An input image copy of the dataset is read, wherein the input image copy is prior to a start of dataset reorganization. A cursor value associated with reorganization of said dataset is determined. A backup copy is produced based on the input image copy, the changes from the log and the cursor value.
