  • Publication number: 20230410947
    Abstract: Mass Spectrometry has been widely used to identify microbes present in a sample. However, rapid analysis (e.g. 1-5 minutes) of spectral data to identify microbes has proven to be very challenging due to the high level of processing required and complexity associated with identification from a large pool of candidate microbes. Disclosed herein are methods and systems for rapidly identifying microbes present in a sample through the application of conditional likelihoods that certain proteoforms are particularly indicative of a candidate microbe.

  • Patent number: 11395587
    Abstract: A vision testing apparatus has a frame including a face plate with at least one eye shield having a viewing slot positioned in a viewing direction perpendicular to the face plate, at least one variable lens element including an outer rail and multiple regions of varying diopter power having a width that is equal to or greater than the width of the viewing slot of the eye shield, and adjustable controls for moving the variable lens element in a direction perpendicularly to the viewing direction along a plane of the face plate. The testing apparatus is portable and can be used in developing nations where visual acuity is not corrected because of lack of access to optometric care.

  • Publication number: 20220112745
    Abstract: A sliding privacy door and lockset system for doors of the types generally known as “barn doors” and/or “pocket doors”, due to these doors being slidably mounted on a rail or rails positioned above a doorway or otherwise in or near a doorway. The present invention includes a lockset comprising a strike plate mounted to a door, and a lockset sub-assembly mounted to a door jamb. The lockset sub-assembly includes an actuating arm connected axially to a rotatable extension of a thumb turn. During operation, the distal end of the actuating arm rotates from an unlocked position to a locked position, that is, the distal end of the actuating arm rests within a slot in the strike plate. The strike plate may include a bump to limit the actuating arm's rotation, and a flush pull handle comprising an opening configured to provide a user's hand(s) with a place to grip.

  • Patent number: 10530193
    Abstract: A first apparatus for passive magnetic field attenuation comprises a wireless power transfer (“WPT”) pad comprising one or more windings and a ferrite structure adjacent to the one or more windings, and a passive magnetic flux cancellation (“PMFC”) structure located adjacent to the WPT pad. The PMFC structure includes one or more vertical shields oriented substantially perpendicular to the WPT pad, where each of the one or more vertical shields attenuates an electromagnetic field, and a vertical shield retention structure that retains each of the one or more vertical shields in position with respect to the WPT pad.

  • Patent number: 10257739
    Abstract: A monitoring and troubleshooting system to determine whether or not an antenna that is used for receiving wireless weak signals, like base station for cellular wireless communication, is operational. The antenna status condition is signaled over the Fiber Optic (FO) link without interfering the signal during normal operation. When a fault is detected the status at the FO receiver is determined. Then, an indication using special signaling allows a service technician to distinguish if the status fault is antenna failure or antenna disconnect. The present invention will also allow a service technician to determine if there is a FO link failure by use of light intensity monitoring. The present invention also includes a method of monitoring the status of a radio frequency antenna with the apparatus as discussed above.

  • Patent number: 9901702
    Abstract: A tracheal tube assembly includes a connector body, a cannula extending from the connector body, and an insert that provides rigidity to the connector body and retains the cannula in the connector body. The cannula has an upper end that fits between conforming tapered sections of the connector body inner surface and the insert. The insert may include features to mitigate stress on and around any secondary lumens in the cannula wall. Because the wall is thinner at the site of a secondary lumen, the connector body insert may include a recess into which the cannula wall may expand. The recess may be aligned with the secondary lumen.

  • Publication number: 20170212286
    Abstract: Color temperature actually emitted by a light emitting diode (LED) is perceived by a viewer of that LED to be altered because of the placement of a passive color temperature-shifting panel between the viewer and the LED. The panel is colored in a manner to cause a perception of a shift from one color temperature of the light emitting diode to another color temperature of the light emitting diode in the absence of any electrochromic, photochromic, or thermochromic material in the panel.

  • Patent number: 9474874
    Abstract: The present disclosure describes systems and methods that utilize a tracheal tube adaptor system. The tracheal tube adaptor system includes a tracheal tube adaptor and/or a flaring jig. A proximal end of a tracheal tube may be flared and the tracheal tube adaptor may be coupled to the proximal end of the tracheal tube. The tracheal tube adaptor may be configured to easily attach and detach an end connector. The end connector may be used to couple a variety of medical devices such as a ventilator, a manual respirator, a nebulizer, a vaporizer, suctioning equipment, and so forth, to the tracheal tube. The use of the tracheal tube adaptor system and methods enables the rapid detachment and attachment of various end connectors, thus allowing the coupling of the tracheal tube to a variety of medical devices.

  • Publication number: 20150097517
    Abstract: Portable electronic devices comprise a housing having one or more straps attached thereto. The straps include battery cells disposed therein that are operatively connected to the housing. The straps comprise a construction material accommodating a number of the battery cells therein, wherein the battery cells are separated from one another to enable bending of the strap to facilitate wearing the device. The battery cells are operatively connected together in the strap by circuits, cables, or conduits. The straps include an attachment element configured to facilitate mechanically connecting the strap to the housing, which attachment element may also facilitate electrical connection with the housing. The straps may be releasibly attached to the housing to permit removal for recharging, or for replacement with charged straps. The straps may also include one or more accessories otherwise disposed in the housing for further reducing device packaging size.
