| 20090011379 | Combustion initiator - The combustion initiator of this invention preferably includes at least two separate combustible chemical constituents including a fuel cell and an ignition pellet. An igniter has a third combustible material thereon which can be manually caused to move and bring the combustible material into contact with the ignition pellet. The combustible material and ignition pellet are highly reactive with one another so that such contact therebetween causes the ignition pellet to commence combustion. The ignition pellet is adjacent the fuel cell and combusts with sufficient temperature to cause the fuel cell to commence combustion. The fuel cell and ignition pellet are preferably contained within an enclosure which protects the igniter from being manipulated unless the enclosure is first opened. The fuel cell material burns hot enough and long enough to cause combustion of surrounding fuels, such as wood. | 01-08-2009 |

| 20090099551 | Sensors and control for an interventional catheter - This invention provides small position sensors for applications where localized sensing in a small volume of space is needed but where measurement of large relative displacement is also necessary. The invention enables a surgeon to accurately position the tip of a catheter during minimally invasive therapy. The current invention further improves the quality of tactile feedback to a physician during catheter-based surgeries with an axial force sensor at the tip of the catheter that allows for the transmission of force information to the physician. One embodiment of this invention is a position sensor for active interventional catheters, where the sensor may be laser-machined shape memory alloy (SMA), and the catheter actuators may be heated SMA or wire-pulleys. Providing position feedback from a catheter during minimally invasive therapy allows for closed-loop control of the catheter tip position under computer-aided guidance and enable force feedback to the physician. | 04-16-2009 |
| 20100174228 | Hypoglycemia prediction and control - A system for predicting hypoglycemia based on continuous blood glucose monitor values is provided. The hypoglycemia detection algorithm is a set of individual alarms that are combined through a voting system into one combined alarm. The system could have five components and an overall voting algorithm that produces a binary alarm outcome depending on the number of constituent algorithms that report an alarm. A controller system automatically shuts off the insulin pump when pending or real hypoglycemia has been reached. The algorithms operate in a closed loop and automatically take action when the subject is asleep. | 07-08-2010 |

| 20110243537 | Motion control of impedance-type haptic devices - A control method for an haptic device is provided with particular attention to motor control amplifiers exploiting the inate motor dynamics of DC motors. The control method encompasses a digital and analog circuit. In the digital circuit, a command voltage is determined by a digital controller utilizing sensed motion information of the haptic device and a motion command signal. In the analog circuit, an amplifier applies a voltage to an electrical DC motor. The applied voltage incorporates the determined command voltage from the digital controller and a voltage to reduce the electrical dynamics of the electrical DC motor. | 10-06-2011 |

| 20120109377 | AUTOFOCUS AND/OR AUTOSCALING IN TELESURGERY - Robotic, telerobotic, and/or telesurgical devices, systems, and methods take advantage of robotic structures and data to calculate changes in the focus of an image capture device in response to movement of the image capture device, a robotic end effector, or the like. As the size of an image of an object shown in the display device varies with changes in a separation distance between that object and the image capture device used to capture the image, a scale factor between a movement command input may be changed in response to moving an input device or a corresponding master/slave robotic movement command of the system. This may enhance the perceived correlation between the input commands and the robotic movements as they appear in the image presented to the system operator. | 05-03-2012 |

| 20100332031 | RATCHETING FOR MASTER ALIGNMENT OF A TELEOPERATED MINIMALLY-INVASIVE SURGICAL INSTRUMENT - A minimally-invasive surgical system includes a slave surgical instrument having a slave surgical instrument tip and a master grip. The slave surgical instrument tip has an alignment in a common frame of reference and the master grip, which is coupled to the slave surgical instrument, has an alignment in the common frame of reference. An alignment error, in the common frame of reference, is a difference in alignment between the alignment of the slave surgical instrument tip and the alignment of the master grip. A ratcheting system (i) coupled to the master grip to receive the alignment of the master grip and (ii) coupled to the slave surgical instrument, to control motion of the slave by continuously reducing the alignment error, as the master grip moves, without autonomous motion of the slave surgical instrument tip and without autonomous motion of the master grip. | 12-30-2010 |
