Patent number: 8907889Abstract: A method is described that involves identifying one or more images of respective one or more fixed markers. Each marker is positioned on or proximate to a display. The images appear on a pixilated sensor within a handheld device. The method also involves determining a location on, or proximate to, the display where the handheld device was pointed during the identifying. The method also involves sending from the handheld device information derived from the identifying of the one or more images of respective one or more fixed markers. The method also involves triggering action taken by electronic equipment circuitry in response to the handheld device's sending of a signal to indicate the action is desired.Type: GrantFiled: January 3, 2011Date of Patent: December 9, 2014Assignee: ThinkOptics, Inc.Inventors: John Sweetser, Anders Grunnet-Jepsen, Kenneth Salsman

Publication number: 20120275929Abstract: A fluid conveyance system includes a flow passage and a cavity adjacent a side of the flow passage. A wall of the passage includes a flexible section that separates the cavity from the flow passage. The cavity contains a ferrofluidic material. The system further includes at least one magnetic field source positioned adjacent the flow channel. The magnetic field source is operable to move the ferrofluidic material in the cavity to exert a pressure on the flexible section and displace the flexible section into the flow passage to alter the flow of material through the passage. A method of collecting components from a sample volume includes the steps of distributing magnetic particles into the sample volume, capturing the components from the sample volume, and applying a magnetic field to the sample volume to control directional flow of the sample volume.Type: ApplicationFiled: June 29, 2011Publication date: November 1, 2012Applicant: APTINA IMAGING CORPORATIONInventor: Kenneth Salsman
