  • DETECTION OF ANTIBIOTIC-RESISTANT MICROORGANISMS
    Publication number: 20150232920
    Abstract: Method of detecting methicillin-resistant S. aureus (MRSA) and methicillin-sensitive S. aureus (MSSA) in a nucleic acid coamplification assay. The invention advantageously reduces the incidence of false-positive MRSA determinations in real-time assays by requiring satisfaction of a threshold criterion that excludes certain co-infections from the MRSA determination. The invention further provides for determination of MSSA, even when the MSSA is present in combination with methicillin-resistant coagulase-negative (MR-CoNS) bacteria at high or low levels.

  • Magnetically guided catheter with concentric needle port
    Patent number: 9017283
    Abstract: A catheter adapted for ablation, mapping, injection, and directional control by an external magnetic system has a catheter body, an intermediate section, and a tip section having a tip electrode configured with an omnidirectional distal end and a concentric needle port. The tip electrode houses a magnetic device and a position sensor arranged in an integrated configuration, wherein the configuration facilitates a path in the tip section for a component, including an injection needle, to extend through the tip section for extension and retraction with reduced stress and friction. The integrated configuration is an efficient use of space in the tip electrode that allows the tip section to carry both the position sensor for determining location and orientation of the tip section and the necessary volume of magnetic or magnetizable material to accomplish magnetic navigation.

  • VIDEO RECORDING FAILOVER
    Publication number: 20150037007
    Abstract: Embodiments disclosed herein provide systems and methods for performing video recorder failover. In a particular embodiment, a system includes a first Network Video Recorder (NVR) configured to receive a video stream and record the video stream to a first long-term storage. The system further includes a second NVR configured to receive the video stream and temporarily stores an amount of the video stream in temporary storage. In response to a detection of a failure of the first NVR, the second NVR is configured to record the video stream to the second long-term storage and transfer at least a portion of the video stream stored in the temporary storage corresponding to the amount of time between detection of the failure and when the second NVR began recording the video stream to the second long-term storage.

  • RELEASABLE MOUNT APPARATUS AND SYSTEM
    Publication number: 20140265765
    Abstract: A mounting system can be used to releasably attach a first item to a second item. In one example, the first item can be a protective encasement for a mobile electronic device, and the second item can be a bicycle mount, suction cup mount, vehicle surface, office surface, or home surface. The mount assembly can include a first housing portion connected to a second housing portion, and can include a cam and torsion spring disposed within a housing volume defined by the first and second housing portions. A recess in the mount assembly can receive and retain a mounting cleat associated with the first item. One or more clasp mechanisms of the mount assembly can be configured to clasp the mounting cleat when it is inserted into the recess and to release the mounting cleat when the first housing portion is rotated relative to the second housing portion.

  • Bandwidth management in a powerline network
    Patent number: 8737420
    Abstract: There is provided a powerline network that includes a number of stations including a central coordinator for coordinating transmissions of each of the stations. Each of the stations is configurable to generate one or more tone maps for communicating with each of the other stations in the powerline network. Each tone map includes a set of tones to be used on a communication link between two of the stations. Each tone map further includes a unique set of modulation methods for each tone. Each of the stations is further configurable to generate a default tone map for communicating with each of the other stations, where the default tone map is valid for all portions of a powerline cycle. Each of the stations is further configurable to monitor its bandwidth needs and to request additional bandwidth from the central coordinator.
