Patent number: 8488295Abstract: A selectively rigidizable and actively steerable device is described. In one aspect, an articulatable device is described that includes a flexible inner tube having a first lumen, a flexible outer tube that receives the inner tube, and a multiplicity of overlapping, rigidizable scale-like strips. Each scale-like strip is coupled with the inner tube and positioned between the inner and outer tubes. Of particular note, the overlapping strips are actuatable between a non-rigidized state in which overlapping strips are slideable relative to one another and a rigidized state in which overlapping strips are not slideable relative to one another.Type: GrantFiled: February 17, 2012Date of Patent: July 16, 2013Assignee: SRI InternationalInventors: Pablo Garcia, Thomas Low, Bryan Chavez, Harsha Prahlad

Patent number: 8321075Abstract: Biodynamic feedthrough in a master control system can be mitigated. An accelerometer is used to measure the acceleration of an environment. In one embodiment, mitigation damping forces can then be determined based on the velocity of an effector of a haptic manipulator and the measured accelerations. The haptic manipulator applies the mitigation damping forces as force feedback. In another embodiment, biodynamic feedthrough can be filtered from the input signal. Parameters for a model can be accessed based on the position of the effector, and the model can be used to predict biodynamic feedthrough from the measured accelerations.Type: GrantFiled: February 24, 2009Date of Patent: November 27, 2012Assignee: SRI InternationalInventors: Thomas Low, Kevin Hufford

Publication number: 20080156320Abstract: A nebulizer and a method for atomizing liquid are provided. The method includes directing liquid from a first chamber to a second chamber in a housing. The second chamber is configured to form standing pressure waves therein when the liquid therein is vibrated. The method further includes vibrating the liquid in the second chamber utilizing a piezo-electric device such that standing pressure waves are formed in the second chamber. The method further includes atomizing liquid in the second chamber as the liquid propagates through a meshed screen wherein the meshed screen is disposed a predetermined distance from the piezo-electric device at a high amplitude region of the standing pressure waves and within a focal region of the piezo-electric device.Type: ApplicationFiled: January 3, 2007Publication date: July 3, 2008Inventors: Thomas Low, Pablo Garcia, Jeff Shimon, Paul T.

Publication number: 20080083671Abstract: Systems and methods for removing lipids from a fluid, such as plasma, or from lipid-containing organisms. A fluid is combined with at least one extraction solvent, which causes the lipids to separate from the fluid or from lipid-containing organisms. The separated lipids are removed from the fluid. The extraction solvent is removed from the fluid or at least reduced to an acceptable concentration enabling the delipidated fluid to be administered to a patient without the patient experiencing undesirable consequences. Once the fluid has been processed, the fluid may be administered to a patient who donated the fluid, to a different patient, or stored for later use.Type: ApplicationFiled: October 8, 2007Publication date: April 10, 2008Applicant: Lipid Sciences, Inc.Inventors: David Bomberger, Bryan Chavez, Pablo Garcia, Eric Hegwer, Thomas Low, Ripudaman Malhotra, Jeffrey Shimon

Publication number: 20070281347Abstract: A device is disclosed for transferring an organism from a donor container to a recipient container. The device comprises a transfer plate assembly comprising a first subassembly and a second subassembly. The transfer plate assembly positions donor containers and recipient containers in an inverted relationship so that the organism pass from the donor container to the recipient container. In addition, a method is presented for transferring a small organism from a donor container to a recipient container. The method includes engaging a donor container to a transfer plate assembly. The method discloses engaging a recipient container to the transfer plate assembly wherein the recipient container is in an inverted orientation to the donor container and rotating the transfer plate assembly so that the recipient container is positioned below the donor container which allows the small organism to be transferred.Type: ApplicationFiled: August 25, 2006Publication date: December 6, 2007Inventors: Matthew Boeckeler, Bryan Chavez, Christopher Cummings, Carol Singh, Thomas Low, Max Crittenden
