20080215065 | Medical robotic arm that is attached to an operating table - A system for performing minimally invasive cardiac procedures includes a pair of surgical instruments coupled to a pair of robotic arms with end effectors that can be manipulated to hold and suture tissue. The robotic arms are coupled to a pair of master handles by a controller to produce a corresponding movement of the end effectors. The movement of the handles is scaled such that the end effectors movement corresponds differently, typically smaller, than the movement performed by the hands of the surgeon. The input button allows the surgeon to adjust the position of the handles without moving the end effector, so that the handles can be moved to a more comfortable position. The system may include a robotically controlled endoscope allowing the surgeon to remotely view a surgical site. The surgeon may manipulate handles and move end effectors to perform a cardiac procedure. | 09-04-2008 |
20080228196 | SURGICAL ROBOTIC SYSTEM FOR PERFORMING MINIMALLY INVASIVE SURGICAL PROCEDURES - The system includes a pair of surgical instruments that are coupled to a pair of robotic arms. The instruments have end effectors that can be manipulated to hold and suture tissue. The robotic arms are coupled to a pair of master handles by a controller. The handles can be moved by the surgeon to produce a corresponding movement of the end effectors. The movement of the handles is scaled so that the end effectors have a corresponding movement that is different, typically smaller, than the movement performed by the hands of the surgeon. The scale factor is adjustable so that the surgeon can control the resolution of the end effector movement. The movement of the end effector can be controlled by an input button, so that the end effector only moves when the button is depressed by the surgeon. The input button allows the surgeon to adjust the position of the handles without moving the end effector, so that the handles can be moved to a more comfortable position. The system may also have a robotically controlled endoscope which allows the surgeon to remotely view the surgical site. A cardiac procedure can be performed by making small incisions in the patient's skin and inserting the instruments and endoscope into the patient. The surgeon manipulates the handles and moves the end effectors to perform a cardiac procedure such as a coronary artery bypass graft. | 09-18-2008 |

20080278571 | STEREOSCOPIC THREE DIMENSIONAL VISUALIZATION SYSTEM AND METHOD OF USE - The present invention relates to a stereoscopic three dimensional visualization system, and particularly to a stereoscopic three dimensional visualization system for microdentistry, microsurgery, or industrial applications. In one exemplary embodiment, the present invention provides a plurality of cameras configured to provide a first stereoscopic image to a dentist or other professional and a second stereoscopic image to an assistant that has approximately the same focal point, but that is rotated by a predetermined angle from the first stereoscopic image. In one exemplary embodiment three cameras are utilized to create the stereoscopic images. | 11-13-2008 |
20090202107 | Object detection and recognition system - An object recognition system is provided including at least one image capturing device configured to capture at least one image, wherein the image includes a plurality of pixels and is represented in an image data set, an object detection device configured to identify a plurality of pixels corresponding to objects from the at least one image, wherein an object includes a plurality of pixels and is represented in an object data set, wherein the object data set includes a set of features corresponding to each pixel in the object, and an image recognition device configured to recognize objects of interest present in an object by image correlation against a set of template images to recognize an object as one of the templates. | 08-13-2009 |
20100014969 | WIND TURBINE WITH BLADE PITCH CONTROL TO COMPENSATE FOR WIND SHEAR AND WIND MISALIGNMENT - A wind turbine or rotor load control compensates for moment imbalance in a wind turbine that includes a rotor having at least two variable pitch blades. The apparatus includes a conventional pitch command logic developing a nominal rotor blade pitch command signal and a moment sensor. The moment sensor can be one or more of a nacelle overturning moment sensor, and a turning moment sensor. An output of this is used as a moment signal. Conversion logic is connected to the moment signal with an output of the conversion logic being calculated individual pitch modulation commands for each of the blades. A combining logic is connected to receive the calculated individual blade pitch modulation commands and to receive a nominal pitch command. An output of the combining logic is individual combined blade pitch commands for each of the blades. The individual combined blade pitch commands are generated by modulating the nominal command signal by a respective blade pitch modulation command which includes compensation for instantaneous moment deviations of the wind turbine. | 01-21-2010 |
20100111693 | WIND TURBINE DAMPING OF TOWER RESONANT MOTION AND SYMMETRIC BLADE MOTION USING ESTIMATION METHODS - A method for wind turbine tower load control includes controlling the pitch of the rotor blades in a conventional manner by a collective command component. An estimator estimates the tower resonant acceleration and the thrice-per-revolution blade imbalance acceleration. Combining logic, connected to the estimated resonant acceleration and to the estimated thrice-per-revolution (3P) acceleration provides a combined pitch modulation to damp the tower resonant motion and the thrice-per-revolution motion using collective modulation. The pitch modulation is combined with the collective command component to drive the pitch actuators. | 05-06-2010 |
20120123605 | Spatial information correlation for control of an energy park - A spatial correlation system and method is disclosed to infer and anticipate the environmental and other conditions of an energy park from individual energy collector information. Individual collector information is acquired and formatted into a pixelized image according to the spatial location of the collector. Image processing and other spatial correlating algorithms are applied to generate spatially correlated descriptions of the energy park. The descriptions are of the current and anticipated conditions. The collectors are made to respond to the descriptions in order to maximize energy collection, avoid disruptive conditions, and reduce stress loading. The system combines locally acquired collection information in a manner that replaces costly collector instrumentation. | 05-17-2012 |
20150078548 | Adaptive Stochastic Queueing - An Adaptive Stochastic Queueing device comprises a process that maintains a plurality of queues defined around the known and changing resource usage history of an ensemble of customers, customers seeking access to a resource. Applying a stochastic approach that reflects the history of each customer in reference to the ensemble history, the queues intercept and sort customers. A stochastic sequencer sequences customers from the queues to the resource in a manner that selectively promotes customers in a manner attuned to the application using the device. | 03-19-2015 |
