Abstract: A medical system that allows a mentor to teach a pupil how to use a robotically controlled medical instrument. The system may include a first handle that can be controlled by a mentor to move the medical instrument. The system may further have a second handle that can be moved by a pupil to control the same instrument. Deviations between movement of the handles by the mentor and the pupil can be provided as force feedback to the pupil and mentor handles. The force feedback pushes the pupil's hand to correspond with the mentor's handle movement. The force feedback will also push the mentor's hand to provide information to the mentor on pupil's movements. The mentor is thus able to guide the pupil's hands through force feedback of the pupil handles to teach the pupil how to use the system.

Abstract: A medical robotic system with a handle assembly that is used to control a medical instrument. The handle assembly and medical instrument have five degrees of freedom. Five degrees of freedom may provide greater dexterity than medical robotic systems of the prior art with four or less degrees of freedom. Five degrees of freedom reduces the size and complexity of the instrument.

Abstract: A medical system that allows a medical device to be controlled by one of two input devices. The input devices may be consoles that contain handles and a screen. The medical devices may include robotic arms and instruments used to perform a medical procedure. The system may include an arbitrator that determines which console has priority to control one or more of the robotic arms/instruments.

Abstract: A system for performing minimally invasive cardiac 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.

Abstract: An anchoring device adapted to be partially buried in a concrete member during forming thereof for cooperation with a pick-up unit, the anchoring device comprising an integrally formed lifting pin and a void former.

Abstract: A system and method for communicating with an integrated circuit is provided that allows an integrated circuit to communicate debugging information and system bus transaction information with an external system. The system may include an interface protocol that provides flow control between the integrated circuit and the external system. The system may include a high-speed link and/or a JTAG link for communicating information. A link may be automatically selected by a debug circuit, or selected by an on-chip device or external system. The high-speed link enables real-time collection of trace information. Links may be memory-mapped, such that on-chip devices and other devices attached to the system bus may access the external system. The high-speed link may also operate at a rate which is integrally coupled with a rate of the processor or system bus. Further, the high-speed link may be adapted to change speeds in response to a change in operating speed of the system bus or processor.

Abstract: Methods and systems in accordance with the present invention provide a peer-to-peer replicated hierarchical data store that allows the synchronization of the contents of multiple data stores on a computer network without the use of a master data store. The synchronization of a replicated data store stored on multiple locations is provided even when there is constantly evolving set of communications partitions in the network. Each computer in the network may have its own representation of the replicated data store and may make changes to the data store independently without consulting a master authoritative date store or requiring a consensus among other computers with representations of the data store. Changes to the data store may be communicated to the other computers by broadcasting messages in a specified protocol to the computers having a representation of the replicated data store.

Abstract: Methods, systems, and articles of manufacture consistent with the present invention provide a system and method for sharing and recording information on a wired or wireless computer network during synchronous and asynchronous sessions. A software program uses computers to enhance the collaboration, teaching, learning, presentation, and sharing of information and to record multi-media events for later playback and interaction with these events. Collaboration is enhanced by using features that allow broadcasting presentations, sharing, editing and replying to documents, taking notes, viewing participant information, creating and responding to polling questions, asking and answering questions and providing feedback on the pace and difficulty of the session.

Abstract: Product information is provided. An indicator that directs the customer to a web-page for the product information. The indicator may be disposed on a label affixed to the product. The indicator may be an URL to the web page. The label may be affixed in a prominent location on the product. The product information may be product specific. In another aspect, the indicator is stored in a memory. The indicator may be programmed into a programmable memory. The product may include a processor for accessing the indicator in memory and automatically establishing the interface between the customer and the web page. In yet another aspect, there is provided a place where the product information is stored that is easily accessed. The place where the product information is stored is easily updatable such as a web page.

Abstract: An instrument guide that can compensate for surgical instruments that have different outer diameters. The instrument guide includes a shaft that has an inner channel adapted to receive a surgical instrument. The guide also has a leaf that can be deflected relative to the shaft to exert a spring force onto the instrument. The amount of leaf deflection is dependent upon the outer diameter of the surgical instrument.

Abstract: A method and apparatus for estimating the orbits of spacecraft or other objects relative to primary celestial bodies, given applicable measurements. The present invention uses the variation of parameters in universal variables for spacecraft trajectory propagation during operation of its optimal sequential orbit estimation. This method provides a universal capability for all three conics: elliptic, parabolic, and hyperbolic, forward-time and backward-time numerical integration for filtering and smoothing, respectively. A method for determining local and global estimates of atmospheric density is also provided. A method for realistic orbit simulation provides a means for validating an orbit estimate.
