Patent number: 9738918Abstract: A rapid one-pass liquid filtration system efficiently concentrates 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. 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. Additional concentration stages may be added in “cascade” fashion, in order to concentrate particles below the size cut of each preceding stage remaining in the separated fluid in a concentrated sample suspension. This process can also be used to create a “band-pass” concentration for concentration of a particular target size particle within a narrow range.Type: GrantFiled: June 24, 2014Date of Patent: August 22, 2017Assignee: InnovaPrep, LLCInventors: David S. Alburty, Andrew E. Page, Zachary A. Packingham, Daniel B. Marske

Publication number: 20160302776Abstract: Devices, systems and methods are disclosed which relate to using wet foam elution for removal of particles from swabs and wipes. This allow users to capture particles from surfaces and recover them by elution into small sample volumes for subsequent detection for human clinical, veterinary, food safety, pharmaceutical, outbreak investigations, forensics, biodefense and bioterrorism response, environmental monitoring, and other applications where collection of samples from surfaces and humans or animals is required. More specifically, the swabs or wipes are used to collect samples in the standard ways that commercially available swabs and wipes are in use today; from, for instance, food preparation surfaces in food plants, from production equipment in pharmaceutical facilities, for collection of dry powders during bioterrorism event response, and for collection of clinical samples such as nasal, throat, nasopharyngeal, and wounds.Type: ApplicationFiled: April 18, 2016Publication date: October 20, 2016Inventors: Alec D. Adolphson, Ann K. Packingham, Andrew E. Page, David S. Alburty, Zachary A. Packingham, John D. Birkenholz, Michael F. Fischer

Publication number: 20160172923Abstract: A motor for an electrohydraulic actuator (EHA). The motor comprises a rotary shaft for rotation about an axis (R), a rotor attached to the rotary shaft and rotatable therewith, a stator surrounding at least a portion of the rotor and a liner disposed between the rotor and the stator. The liner defines an axially extending chamber around the rotor for retaining a fluid between the rotor and the liner. The liner comprises a tubular body having an open end and a closed end. An EHA comprising the motor is also claimed.Type: ApplicationFiled: December 7, 2015Publication date: June 16, 2016Inventors: Chris H. A. Claycomb, Andrew E. Page

Publication number: 20070251386Abstract: A system and associated methods are disclosed for facilitating efficient collection of entrained material from an air/gas sample. In one arrangement, a method for collecting entrained material from a sample involves a dry collection cyclonic cycle combined with a period of fluid wash use. In particular, a sample is drawn into a chamber of a cyclone separator having a perimeter wall, and then a dry collection cyclonic separation cycle is performed on the sample for a period of time to separate a substantial amount of the entrained material from the sample. Subsequent to or temporally near an ending point of the dry collection cyclonic separation cycle, a fluid wash is injected into cyclone separator chamber so as to direct the fluid wash along the perimeter wall to capture material deposited on the walls and in the vortex break at the bottom of the cyclone separator.Type: ApplicationFiled: April 25, 2007Publication date: November 1, 2007Applicant: SCEPTOR INDUSTRIES INC.Inventors: FREEMAN J.

Patent number: 6666905Abstract: A thermoelectric particle precipitator for removing and collecting particles from a fluid stream. The thermoelectric particle precipitator utilizes one or more thermoelectric modules to create a temperature gradient which causes suspended particles in a fluid stream to undergo thermophoretic movement and precipitate on a surface on the cooled side of the temperature gradient. The collection surface may be a cooled surface of the thermoelectric module or a cooled surface of a thermal mass. The collected particles may be analyzed to determine their composition.Type: GrantFiled: April 27, 2001Date of Patent: December 23, 2003Assignee: Midwest Research InstituteInventors: Andrew E.
