  • MEDIA DRIVE RESTRAINT AND METHOD FOR DETECTING A CLOSED MEDIA TRAY
    Publication number: 20160361932
    Abstract: In one embodiment, a device for a printer includes a movable tray for supporting a print media. The tray is movable between an open position in which media may be moved on to the tray and a closed position in which media is blocked from moving on to the tray. The device also includes a rotatable media drive component for moving print media on to the tray and a movable restraint operatively connected to the tray. The restraint is movable between: a first position, corresponding to the open position of the tray, in which the restraint does not restrain the media drive component; and a second position, corresponding to the closed position of the tray, in which the restraint restrains rotation of the media drive component.

  • CLEANING APPLIANCE
    Publication number: 20160331116
    Abstract: A dental cleaning appliance includes a handle, a fluid reservoir for storing a working fluid, and a fluid delivery system for receiving working fluid from the fluid reservoir, and for delivering the working fluid to the teeth of a user. The fluid reservoir is delimited by a wall and a movable member which is moveable relative to the wall to vary the volume of the fluid reservoir. An expansion chamber is located adjacent to the moveable member. The volume of the fluid reservoir decreases, and the volume of the expansion chamber increases, as fluid is supplied to the fluid delivery system during use of the appliance.

  • DETECTION OF STENOSIS IN A PROSTHESIS USING BREAK FREQUENCY
    Publication number: 20160256107
    Abstract: A method for detecting a stenosis in a prosthesis includes providing a tubular prosthesis having a sensor coupled to the prosthesis and implanting the tubular prosthesis in a native fluid conduit. The sensor senses the stenosis and captures data that characterizes the stenosis. A spectral analysis of the data may then be performed in order to provide a frequency spectrum of the data. The frequency spectrum may be examined in order to identify a break frequency value in the frequency spectrum. The break frequency may then be translated into a percentage of stenosis in the tubular prosthesis.
