Publication number: 20140035306Abstract: Robotic hands and finger modules include an under-actuated finger with multiple joints including a distal joint, an intermediate joint, and a proximal joint. A brake subsystem in communication with each of the joints selectively locks and unlocks the joints individually. A robotic hand can selectively lock the joints of a finger individually such that one or more joints are locked while one or more joints are unlocked. In addition, the finger module can drive a tendon coupled to the joints to flex the underactuated finger in a manner determined by which of the joints is locked and which of the joints is unlocked. A robotic hand can move an underactuated finger with its distal and proximal joints unlocked until the finger makes contact with an object, and lock the proximal joint, in response to contact made with the object, while the distal joint remains unlocked.Type: ApplicationFiled: March 21, 2012Publication date: February 6, 2014Applicant: SRI InternationalInventors: Pablo E. Garcia, Thomas P. Low, Harsha Prahlad, Daniel Aukes, Susan Kim, Roy D. Kombluh

Publication number: 20140031983Abstract: A robotic manipulator has a body and a stereoscopic video system movably coupled to the body. The stereoscopic vision system produces a stereoscopic video of an environment of the robotic manipulator. The robotic manipulator also includes two independently remotely controlled arms coupled to opposite sides of the body. Each arm moves in proprioceptive alignment with the stereoscopic video produced by the stereoscopic video system in response to commands received from a remote control station based on movements performed by an operator at the remote control station.Type: ApplicationFiled: March 21, 2012Publication date: January 30, 2014Applicant: SRI INTERNATIONALInventors: Thomas P.

Publication number: 20130294875Abstract: An electroadhesive gripping platform includes one or more electrodes. A power supply is configured to apply voltage to the one or more electrodes in the electroadhesive platform via one or more terminals. A controller is configured to operate the electroadhesive gripping platform to selectively adhere to items loaded thereon and thereby enhance traction control over such items. The controller can control the power supply to apply a voltage to the one or more electrodes in the electroadhesive platform to thereby cause the electroadhesive platform to adhere to an item disposed on the electroadhesive platform such that the item resists moving with respect to the electroadhesive platform. The controller can also control the voltage supply to reduce the voltage applied to the one or more terminals such that the item moves with respect to the electroadhesive platform.Type: ApplicationFiled: May 2, 2013Publication date: November 7, 2013Applicant: SRI InternationalInventors: Harsha Prahlad, Ronald E. Pelrine, Brian K. McCoy, Thomas P. Low

Publication number: 20100213928Abstract: A piston rod position sensing system includes a cylinder and a piston rod arranged in the cylinder for movement with respect thereto. A magnetically hard layer is formed on the piston rod to provide a recording medium. A magnetic pattern is recorded in the magnetically hard layer. The magnetic pattern includes tracks recorded in the magnetically hard layer lengthwise of the piston rod. Each track comprises magnetically written regions used to identify a current position of the piston rod. The sensing system also includes a plurality of magnetic field sensors in greater number than the plurality of tracks. Each magnetic field sensor senses the magnetically written regions of one or more of the tracks while the piston rod is moving with respect to the cylinder and generates signals used for detecting rotation of the piston rod in response to the sensed magnetically written regions.Type: ApplicationFiled: May 5, 2010Publication date: August 26, 2010Applicant: SRI INTERNATIONALInventors: Thomas P.

Publication number: 20090032468Abstract: This invention is directed to systems and methods for removing lipids from a fluid, such as plasma, or from lipid-containing organisms. These systems contact a fluid with an extraction solvent, which causes the lipids in the fluid to separate from the fluid or causes lipids in the lipid-containing organisms to separate from the lipid-containing organism, using at least one hollow fiber contactor. The separated lipids are removed from the fluid. The extraction solvent is removed from the fluid or at least reduced to a level below a particular threshold enabling the 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 be stored.Type: ApplicationFiled: October 8, 2007Publication date: February 5, 2009Applicant: Lipid Sciences, Inc.Inventors: David C.
