Patent number: 8543240Abstract: In a minimally invasive surgical system, a hand tracking system tracks a location of a sensor element mounted on part of a human hand. A system control parameter is generated based on the location of the part of the human hand. Operation of the minimally invasive surgical system is controlled using the system control parameter. Thus, the minimally invasive surgical system includes a hand tracking system. The hand tracking system tracks a location of part of a human hand. A controller coupled to the hand tracking system converts the location to a system control parameter, and injects into the minimally invasive surgical system a command based on the system control parameter.Type: GrantFiled: September 21, 2010Date of Patent: September 24, 2013Assignee: Intuitive Surgical Operations, Inc.Inventors: Brandon D.

Patent number: 8271130Abstract: An input device includes a handle coupled to a base by a linkage. The handle is manually movable relative to the base to provide a position input. The linkage has a plurality of links including a redundant link that permits internal motion of the linkage such that the linkage can move without moving the handle relative to the base. When a distance between the handle and a handle stop position is less than a threshold distance, a handle stop applies a first load to the handle. A drive system applies a second load to the redundant link responsive to the first load to create internal motion of the linkage that increases a distance between the handle and a handle stop position. The second load may be proportional to a cosine of an angle between a handle axis of motion and a redundant link axis of motion.Type: GrantFiled: March 17, 2009Date of Patent: September 18, 2012Assignee: Intuitive Surgical Operations, Inc.Inventor: Arjang Hourtash

Patent number: 8251628Abstract: A joint tong apparatus for a radiation shielding facility. A spherical ball has a through-hole. An inner spherical socket and an outer spherical socket are installed in a hole formed in a partition between a radiation-shielded room and a control room so as to enclose the spherical ball on inner and outer sides. A bar is inserted and coupled into and to the through-hole of the spherical ball. An inner joint assembly has a first housing coupled to a shielded room-side end of the bar and a first pivot member pivotably mounted on a free end of the first housing. An outer joint assembly having a second housing coupled to a control room-side end of the bar and a second pivot member pivotably mounted on a free end of the second housing. The apparatus further includes a tong assembly, a handle assembly, a tong manipulation cable, and a pair of pivot manipulation cables.Type: GrantFiled: October 28, 2008Date of Patent: August 28, 2012Assignees: Korea Atomic Energy Research Institute, Korea Hydro & Nuclear Power Co., Ltd.Inventors: Eun Pyo Lee, Won Myung Choung, Dong Hee Hong, Jeong Hoe Ku, Won Kyung Lee, Il Je Cho, Dong Hak Kook, Kie Chan Kwon, Gil Sung You, Ji Sup Yoon

Patent number: 8066088Abstract: A biologically inspired climbing device with toes and spines is provided. The device has toes capable of moving independently from each other. Each toe distinguishes a compliant linkage, which has non-compliant parts and compliant parts. Spines are distributed over each of the toes. The spines have a diameter that is less than or equal to a diameter of an asperity of a surface. The toes with spines could be arranged into one or more feet. The feet could then be organized in legs enabling the device to climb a surface in a gait pattern. The device uses low power and is quiet, leaves no traces or tracks behind, works well on smooth, rough, uneven, porous and dirty surfaces, and is able to carry and support its own body weight.Type: GrantFiled: December 9, 2005Date of Patent: November 29, 2011Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Alan T. Asbeck, Sangbae Kim, Mark R. Cutkosky

Patent number: 8052185Abstract: A robotic hand with finger assemblies to better simulate human hand form factors and gestures. For each finger assembly, the robotic hand includes a finger drive assembly that is operable to selectively apply tension to four elongated and flexible tension elements (e.g., steel cable). Each of the finger assemblies includes a set of links or link members that are actuated or moved by the selective tensioning/movement of the tension elements by the drive assembly. The links are interconnected with pivotal joints such that they have three degrees-of-freedom, and the finger assembly includes a set of pulleys that are supported on the links and that are arranged to provide support and to guide the tension elements through the finger assembly. The tension elements preferably extend only partially about any one of the pulleys, whereby the finger assembly utilizes “n+1” actuation with non-helical wrapping of the tension elements.Type: GrantFiled: April 9, 2009Date of Patent: November 8, 2011Assignee: Disney Enterprises, Inc.Inventor: Akhil J.

Patent number: 7862522Abstract: A Sensor glove is an instrument, in the same way that a piano is an instrument. The Sensor glove is purchased and the owner then learns to use it and the sensors therein to develop the performance of a sound, character or model, or to “conduct” or “play” the sensor movements and experience the response of the model in real time. Several performers with a number of the Sensor glove can control over 200 motors or hundreds of control points on a character at one time, manipulate audio data, or computer images etc. The characteristics of the sensors on the gloves can be adjusted to the needs and demands of the wearer or the many performer and wearers in those venues where multiple performers are used with many gloves to control or produce the motions and sounds of many distinct characters in a screen play.Type: GrantFiled: August 8, 2006Date of Patent: January 4, 2011Inventors: David Barclay, Glenn Silver, Johan Versteegh, Bruce Lanoil
