20080319313 | COMPUTER-ASSISTED SURGERY SYSTEM WITH USER INTERFACE - A method for establishing an interaction between an operator and a monitor of a computer-assisted surgery system comprises tracking a tool manipulated by the operator for providing surgical data calculated from the position/orientation of the tool. A desired interaction is identified from the operator by tracking the tool reaching a specific position and/or a specific orientation. An interactive action is activated on a monitor as a function of the desired interaction, the interactive action being unrelated to said surgical data. A motion of the tool is converted to additional interactions related to said interactive action. A computer-assisted surgery system is also provided. | 12-25-2008 |
20090125117 | LEG ALIGNMENT AND LENGTH MEASUREMENT IN HIP REPLACEMENT SURGERY - A CAS system for measuring surgical parameters during hip replacement surgery comprises a first tracking reference in fixed relation with the pelvis to form a frame of reference. A registration tool is trackable. A sensor apparatus tracks the first tracking reference and the registration tool. A controller unit receives tracking data for the first trackable reference and the registration tool. The controller unit has a position and orientation calculator for calculating from the tracking data a position and orientation of the pelvic tracking reference to track the frame of reference, and of the registration tool to produce femoral models at a first and a second sequential operative steps. An alignment adjustor aligns the femoral models with the frame of reference. A surgical parameter calculator calculates surgical parameters as a function of the femoral models as aligned by the alignment adjustor. | 05-14-2009 |
20110218458 | MEMS-BASED METHOD AND SYSTEM FOR TRACKING A FEMORAL FRAME OF REFERENCE - A system for tracking a femoral frame of reference in computer-assisted surgery comprises a sensor unit. The sensor unit is adapted to be secured to the femur. The sensor unit comprises accelerometer and gyroscope sensors that produce orientation data. A processing unit receives gyroscope and accelerometer data. The processing unit comprises a gyroscope-data calculator to provide calculated acceleration data resulting from movements of the femur, an accelerometer-data calculator to calculate measured acceleration data resulting from movements of the femur, and an acceleration comparator to relate an orientation of the sensor unit to the femur to define a femoral frame of reference. The femoral frame of reference is defined from the comparison between the calculated and the measured acceleration data. A sensor orientation interface provides orientation data for the femur from a tracking of the femoral frame of reference. A method for tracking a femoral frame of reference is also provided. | 09-08-2011 |
20120277634 | TRACKING SYSTEM AND METHOD - A tracking system is provided for tracking objects. A first and a second trackable member each have an inertial sensor unit producing at least orientation-based data. A processing unit receives the orientation-based data from the trackable members. The processing unit has an orientation calculator calculating an orientation of the second trackable member with respect to the first trackable member from the orientation-based data of the trackable members, whereby the processing unit calculates an orientation of the objects. A method for tracking objects is also provided. | 11-01-2012 |
20140364858 | ACETABULAR CUP PROSTHESIS POSITIONING INSTRUMENT AND METHOD - A method for assisting in positioning the acetabular cup comprises orienting a cup positioning instrument with a cup thereon in an initial reference orientation relative to an acetabulum of a pelvis with the cup forming a joint with the acetabulum, the cup positioning instrument comprising an inertial sensor unit with pre-planned orientation data for a desired cup orientation based on at least one landmark of the pelvis, The cup positioning instrument is rotated to a desired abduction angle as guided by an interface of the cup positioning instrument, based on movements relative to at least one landmark. The cup positioning instrument is rotated to a desired anteversion angle as guided by the interface of the cup positioning instrument, based on movements relative to the at least one landmark. Upon reaching the desired cup orientation as indicated by the interface, the cup is impacted into the acetabulum. | 12-11-2014 |

The system includes a usage processing engine configure to identify direct and indirect usage data elements for the target data element within the data element structure and a user interface configured to display the direct and indirect usage data elements for the target element in a hierarchical structure. | 01-29-2009 |
20090030928 | System and method for embedded expression assignment - A system for generating embedded expressions configured to generate a result. The system includes an embedded expression generation engine configured to generate a root expression, including at least one parameter. The parameter includes an assigned embedded expression configured to generate a result based on one or more input parameters. The system further includes an embedded expression user interface configured to display the root expression and associated parameters and embedded expressions and provide expression generation tools allowing the user to modify the root expression. | 01-29-2009 |
20090030929 | System and method for providing a virtual item context - A virtual item set representing a subset of items stored within an original data structure. The system includes a virtual item set processor configured to generate a plurality of virtual items that are a subset of items in the original data structure, and a virtual item set including the plurality of virtual items. Each virtual item includes a data field containing a data item from the original data structure and a metadata field, the meta field data including position information representing the position of the data field within an original data structure. | 01-29-2009 |
20150112896 | Cross-Channel Content Translation Engine - An embodiment according to the present invention addresses reusability and alignment of content across channels in a multi-channel virtual assistant, by allowing users to define content on one channel and then have the content fully or partially translated for the other channels using a mix of pre-defined static rules, dynamic rules or machine learning. Content translation is provided based on communications channels, and content translation is performed from one to many formats, optionally in real time. Performing content translation using machine learning provides an advantage that as users work, content translation becomes more precise and covers more elements. | 04-23-2015 |
