20080246761 | Systems for hybrid geometric/volumetric representation of 3d objects - The invention provides a system for modeling three-dimensional objects using hybrid geometric/volumetric representation, wherein sharp edges are created by a geometric representation that is connected to the volumetric representation. The system creates, maintains, and updates the hybrid representation according to user input. The system also provides for conversion of the hybrid representation into either a wholly geometric representation or a wholly volumetric representation, as may be needed for output to a given device, such as a display device, a printer, and/or a fabricating device. | 10-09-2008 |
20080261165 | Systems for haptic design of dental restorations - The invention provides systems for integrated haptic design and fabrication of dental restorations that provide significant advantages over traditional practice and existing computer-based systems. The systems feature technical advances that result in significantly more streamlined, versatile, and efficient design and fabrication of dental restorations. Among these technical advances are the introduction of voxel-based models; the use of a combination of geometric representations such as voxels and NURBS representations; the automatic identification of an initial preparation (prep) line and an initial path of insertion; the ability of a user to intuitively, haptically adjust the initial prep line and/or the initial path of insertion; the automatic identification of occlusions and draft angle conflicts (e.g., undercuts); the haptic simulation and/or marking of occlusions and draft angle conflicts; and coordination between design output and rapid prototyping/milling and/or investment casting. | 10-23-2008 |
20090248184 | Haptically enabled dental modeling system - The invention provides a digital dentistry system that utilizes a haptic interface and features a computer-based design application configured to allow the intuitive construction of irregular, amorphous three-dimensional structures typically seen in dental restorations, utilizing, where appropriate, the design skills of a user. In certain embodiments, the system provides a comprehensive digital solution for dental labs in the business of creating dental restorations such as partial frameworks, crowns, copings, bridge frameworks, implants and the like, with a sense of touch provided by a haptic interface device. | 10-01-2009 |
20110118748 | PATIENT-SIDE SURGEON INTERFACE FOR A MINIMALLY INVASIVE, TELEOPERATED SURGICAL INSTRUMENT - A patient-side surgeon interface provides enhanced capabilities in using a minimally invasive, teleoperated surgical system. The patient-side surgeon interface has components within the sterile surgical field of the surgery. The components allow a surgeon to control teleoperated slave surgical instruments from within the sterile surgical field. The patient-side surgeon interface permits a surgeon to be in the sterile surgical field adjacent a patient undergoing surgery. Controlling minimally invasive slave surgical instruments from within the sterile surgical field permits minimally invasive surgery combined with direct visualization by the surgeon. The proximity to the patient allows the surgeon to control a teleoperated slave surgical instrument in tandem with controlling manually controlled instruments such as a laparoscopic instrument. Also, the surgeon, from within the sterile surgical field, can use the patient-side surgeon interface to control at least one proxy visual in proctoring another surgeon. | 05-19-2011 |
20110118752 | METHOD AND SYSTEM FOR HAND CONTROL OF A TELEOPERATED MINIMALLY INVASIVE SLAVE SURGICAL INSTRUMENT - In a minimally invasive surgical system, a hand tracking system tracks a location of a sensor element mounted on part of a human hand.
