Patent number: 8726744Abstract: The present disclosure provides devices, systems and methods for concentrating a fluid sample. A portable or hand-held concentrator is used to draw the fluid sample through a filter into an internal chamber, capturing target particles on the filter. An elution cartridge containing an elution fluid is used to recover the captured particles into a reduced fluid volume. The hand-held concentrator includes a tip, which, when opened, allows the hand-held concentrator to draw the fluid sample into the tip and through the filter wall into the internal chamber. The drawing occurs due to a vacuum or wicking source in the internal chamber of the hand-held concentrator. The target particles are captured on the filter. The elution fluid contains a foaming agent and is held under a head pressure of gas soluble in the elution fluid. The target particles are eluted from the filter into the reduced fluid volume using an elution foam that is formed when the elution fluid is released from the elution cartridge.Type: GrantFiled: February 16, 2011Date of Patent: May 20, 2014Assignee: InnovaPrep LLCInventors: David Scott Alburty, Andrew Edward Page, Alec D.

Publication number: 20140076071Abstract: Devices, systems and methods are disclosed which relate to using a wet foam elution method for removal of particles from a flat filter. Particles are captured from the atmosphere onto the flat filter. The flat filter is then placed into an extractor which passes a stream of wet foam through the flat filter. Expansion of the foam works to efficiently remove captured particles. The foam flows from the filter along with the captured particles into a sample container. Once in the sample container, the foam quickly breaks down leaving an analysis ready liquid sample.Type: ApplicationFiled: November 19, 2013Publication date: March 20, 2014Applicant: INNOVAPREP LLCInventors: Andrew Edward Page, David Scott Alburty, Alec D.

Publication number: 20140073034Abstract: 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. All conduits by which the disposable tip attaches to the instrument are combined into a single connection point on the upper end of the tip.Type: ApplicationFiled: November 19, 2013Publication date: March 13, 2014Applicant: INNOVAPREP LLCInventors: Andrew Edward Page, Zachary A.

Patent number: 8144021Abstract: A device for detecting the presence of bodily fluid, the device including a detector (1) means having two spaced apart electrodes (2, 3), each electrode is connected to a signal generating means via a lead (6, 7). The electrodes are encased in a flexible non-conductive material with each including at least one protruding conductive element (4). The protruding elements are separated by the same distance as the spacing between the two electrodes. The device also includes a signal processing means that detects a change of state across the electrodes produced by the introduction of a fluid and an alarm actuated by the change of state.Type: GrantFiled: May 12, 2005Date of Patent: March 27, 2012Assignees: Whalley, Robin as Trustee of the Olfarse Trust, Le Gros, Paul Donald as Trustee of the Olfarse TrustInventor: Anthony Edward Page

Patent number: 7804887Abstract: The present invention is a dramatically enhanced RF link for low-data-rate applications (1-100 bps), using one or more transmitters to communicate with one or more receivers, at dramatically enhanced ranges. The receiver of the present invention can rapidly search, detect, and lock in on narrow band signal transmissions, that may be present in a much larger frequency band and which may be changing frequency during the duration of the message. These receivers enable ultra-low noise floor detection of longer range, more highly attenuated, signal transmissions, by decreasing the receiver bandwidth.Type: GrantFiled: November 10, 2009Date of Patent: September 28, 2010Assignee: Applied Research Associates, Inc.Inventor: Edward A.
