Patent WO-2018227161-A1 (WO)
Inventor: PENNIE PATRICK
IPC: A61M1/36
Filed: 2018-06-08
Abstract: A dual piston centrifuge tube includes an elongate tubular receptacle having upper and lower ends interconnected by a sidewall. First and second common inlet/outlet ports are formed respectively in the upper and lower ends of the tubular receptacle. First and second liquid impermeable pistons are mounted within an interior chamber of the tubular receptacle for sliding longitudinally therein. The first piston is interconnected to the first port by a flexible fluid-conducting pipe that extends through the first piston to communicate with a region of the chamber between the first and second pistons. Blood or other biological fluid is introduced through the first port and pipe into the tubular receptacle to drive the first piston upwardly. The tube is centrifuged to separate the fluid into a plurality of constituent component levels between the first and second pistons. One of the layers is aspirated through the pipe and first port and re-introduced into the receptacle through the second port. The tube is centrifuged a second time to separate the re-introduced fluid into constituent components, which are then aspirated through the second port.

Title: Fractionating and refining system for engineering fibers to improve paper production
Inventor: COWAN JOFFREY
IPC: D21G9/00
Filed: 2018-06-29
Abstract: A system for treating cellulosic fibers to improve paper, board and tissue quality; the system involves splitting fibers into an original portion having original fibers and a refinable portion. The refinable portion may further be fractionated by one or more fibers properties by a fiber fractionation system into a first fraction and a second fraction. The refinable portion as a whole, or a fractionated fraction thereof, is then refined to produce refined fibers. Varying amounts of the original unrefined fibers, refined fibers and possibly additionally fractionated unrefined fibers are blended together to form an optimized slurry that is processed by a paper machine into an optimized paper product. A master control system, fiber measurement system and optional fractionation maintenance system may be integrated with the overall system to regulate all processing.

Title: Method to increase the bandwidth of a usb-c connector
Inventor: BISSON LUC
IPC: G06F13/42
Filed: 2018-10-17
Abstract: This disclosure provides a method that allows connector pins of a USB-C connector to be dynamically repurposed between low bandwidth USB2 traffic and high bandwidth USB3 traffic. USB-C devices can negotiate the use of these pins for a dynamic transition to another function or functions. The pins can be the four center connector pins of a USB-C connection, pins A6, A7, B6, B7, that are originally designated as USB 2.0 differential pairs. Changing the function of the pins provides flexibility for communicating using USB-C connectors. For example, the disclosed method/device/system can be used to support high-resolution cameras and sensors in high-resolution virtual reality headsets via a single USB-C connection instead of a user having to connect multiple cables.

Title: Deblocking filter for video coding and processing
Inventor: DONG JIE
IPC: H04N19/14
Filed: 2019-04-02
Abstract: Deblocking is a step in video coding for removing distortions that may result from dividing a video frame into blocks, and encoding the video frame based on the blocks. Techniques described herein can include determining the activity in neighboring blocks along the boundary of the blocks, where the activity measures smoothness or complexity of pixels in the boundary area. An average of the activity can then be determined, as well a difference in the activity between the left block and the right block. The average activity and the difference in activity can then be used to determine a classification for the boundary area. The classification can further be used to select a filter to apply to the pixels in the boundary area. Once the filter have been applied, the blocks can be added to a reconstructed video frame.
