Abstract:
The shape and orientation of rigid or nearly rigid moveable bodies are determined using a shape characterization. Sensors capture a plurality of representations of different perspectives of the body that are analyzed to determine a bounding volume of the body. The shape of the body is determined from the bounding volume. The position of the body is determined using tracking devices that sense the position of the body. The bounding volume and position information are combined to define the shape and orientation in space of the body, and in particular the position of a point of interest on the body.
Abstract:
A surgical tool system with a powered tool that includes a memory in which data describing the characteristics of the power signals that are to be sourced to the toll are stored. A control console based on the data in the tool memory sources the power signal to the tool. Both the data signals written out from the tool memory and the power signals from the console are exchanged over common console terminals and common tool terminals. An isolation circuit in the tool prevents the applied power signals from the console from adversely effecting the tool memory.
Abstract:
A method of registering an article having a surface to previously created scan data of the article includes the steps of providing a flexible substrate having multiple tracking points attached to the substrate, applying the substrate to the article to be registered, creating a model of the surface of the article from a location of each tracking point; and registering the model with the previously created scan data. A method of creating a model of a surface having a shape and an article to enable the creation of a model of a surface are also disclosed.
Abstract:
An article to enable the creation of a model of a surface includes a flexible substrate and multiple optical tracking points attached to the flexible substrate at predetermined location. The optical tracking points can be tracked by a tracking system, and a data link enables communication from the flexible substrate to a tracking system. Also disclosed is an article that enables the creation of a model of a surface including multiple light emitting diodes attached to the flexible substrate at predetermined locations. Finally, a method of registering an article and a method for creating a model of a surface having a shape are disclosed.
Abstract:
A marker for use with a surgical navigation system for tracking the tissue with which the marker is associated. The overall dimensions of the mark is such that it is shaped to be disposed below the skin of the patient in which the marker is implanted. The marker has a stem or a spike that allows the marker to be implanted in hard tissue such as bone. A head, containing navigation system components is located above the stem or spike. Once the procedure is completed the marker is removed from the patient by breaking the head free from the stem Alternatively the head may be rotated to cause the whole of the marker to break free from the bone in which the marker is implanted.

Abstract:
A system and method for locating cutting accessories such as saw blades that, when actuated by the complementary driver, move relative to the driver. The saw blade is provided with one or more geometric features. The location of these features is identified by a pointer. The pointer is part of a surgical navigation system used to monitor the position of the driver to which the saw blade is attached. Based on the location of the geometric features, data regarding the head of the saw blade are generated. Thus, the surgical navigation has data indicating the position and orientation of the driver and the position of the head of the cutting accessory relative to the driver. Based on these data, the surgical navigation system generates data indicating the position and orientation of the head of the saw blade or like cutting accessory.
Abstract:
A portable energy meter test system for testing energy meters and other related instrumentation on-site is disclosed. The test system utilizes waveform generating circuitry to generate and transmit electrical waveforms to an energy meter to be tested, and sensing circuitry for sensing electrical characteristics corresponding to the transmitted electrical waveform. The test system includes a processor for evaluation and control of the testing procedure. A graphic touch screen is coupled to the processor for displaying information about the energy meter and for displaying test options to the user and allowing the user to control the testing process by touching the screen.
