Patent CA-2919650-A1 (CA)
Inventor: CHARLESWORTH OLIVER
IPC: G01V1/28
Filed: 2014-04-23
Abstract: A finite difference wavefield modeling framework decouples the tasks of physical modeling and hardware-software optimization through the use of a platform-agnostic intermediate representation in the form of a dataflow graph. In at least some embodiments a wavefield simulation method includes specifying a kernel of operations to be applied at each point in a space and representing the kernel as a platform-agnostic dataflow graph. For each of multiple implementation platforms, the method further includes: deriving from the platform-agnostic graph a customized graph for the implementation platform; translating the customized graph into configuration information for the implementation platform; supplying the configuration information to the implementation platform to obtain a wavefield simulator; and employing the wavefield simulator to repeatedly apply said kernel of operations to each point in the space with specified input or output signals.

Patent CA-2921945-A1 (CA)
Inventor: HOLMER MATTIAS
IPC: A61B5/021
Filed: 2014-09-08
Abstract: A filtering device receives a signal from a pressure sensor in an extracorporeal fluid circuit connected to a subject and processes the signal to separate physiological pulses, e.g. from the subject's heart, from interference pulses, e.g. from a pump in the fluid circuit. The device repeatedly (iteratively) processes a signal segment by alternately subtracting (S3) a template signal from the signal segment, and applying a refinement processing (S6) to the resulting difference signal to generate a new template signal. By proper selection (S2) of the initial template signal, consecutive difference signals will alternately approximate the sequence of interference pulses in the signal segment and the sequence of physiological pulses in the signal segment. The refinement processing (S6) aims at alternately cleaning up unwanted residuals from interference pulses and physiological pulses, respectively, in the respective difference signal, so as to improve the accuracy of the template signal between the subtractions.

Title: Liquid to liquid biological particle concentrator with disposable fluid path
Inventor: PAGE ANDREW EDWARD
IPC: G01N1/40
Filed: 2014-02-26
Abstract: Highly efficient and rapid filtration-based concentration devices, systems and methods are disclosed with sample fluidic lines and a filter packaged in a disposable tip which concentrate biological particles that are suspended in liquid from a dilute feed suspension. A sample concentrate or retentate suspension is retained while eliminating the separated fluid in a separate flow stream. The concentrate is then dispensed from the disposable tip in a set volume of elution fluid. Suspended biological particles include such materials as proteins/toxins, viruses, DNA, and/or bacteria in the size range of approximately 0.001 micron to 20 microns diameter. Concentration of these particles is advantageous for detection of target particles in a dilute suspension, because concentrating them into a small volume makes them easier to detect. A single-use pipette tip includes fluid ports for aspirating the sample and connecting to a concentrating unit.
