  • Patent number: 9530006
    Abstract: A method for performing a memory safety check of a program coded in an unmanaged programming language includes receiving an intermediate representation (IR) of the program and performing a static analysis pass of the IR to generate annotations including a safe pointer and an unsafe pointer. The method further includes removing, during a static analysis pass of the IR, the safe pointer from the annotations, inserting, into the IR using the annotations, a sandbox function call at the unsafe pointer to generate a modified IR, compiling the modified IR to generate an executable version of the program, executing, inside a sandbox framework, the executable version of the program, generating, during runtime and upon reaching the sandbox function call, a metadata entry and an enhanced pointer for atomicity, and comparing, during runtime and upon reaching a use of the unsafe pointer, the metadata entry with the enhanced pointer.

  • Patent number: 8121718
    Abstract: Interactive, computer based orthodontist treatment planning, appliance design and appliance manufacturing is described. A scanner is described which acquires images of the dentition which are converted to three-dimensional frames of data. The data from the several frames are registered to each other to provide a complete three-dimensional virtual model of the dentition. Individual tooth objects are obtained from the virtual model. A computer-interactive software program provides for treatment planning, diagnosis and appliance from the virtual tooth models. A desired occlusion for the patient is obtained from the treatment planning software. The virtual model of the desired occlusion and the virtual model of the original dentition provide a base of information for custom manufacture of an orthodontic appliance.

  • Patent number: 7752028
    Abstract: Architecture for efficient translation and processing of PowerPC guest instructions on an x86 host machine. In an x86-based architecture, signed integer values are projected into the unsigned integer value space for processing by the host using the negation of the left-most (sign) bit. Compare operations are performed in the unsigned space and the compare results are written into the host flags register. Once the compare results are written into the host flags register, the flag values can be read out and used in a table lookup to retrieve the corresponding values for the guest register. The guest flag values are then passed into the guest flags register for processing by the guest application.

  • Patent number: 7585172
    Abstract: An interactive, software-based treatment planning method to correct a malocclusion is described. The method can be performed on an orthodontic workstation in a clinic or at a remote location such as a lab or precision appliance manufacturing center. The workstation stores a virtual three-dimensional model of the dentition of a patient and patient records. The virtual model is manipulated by the user to define a target situation for the patient, including a target archform and individual tooth positions in the archform. Parameters for an orthodontic appliance, such as the location of orthodontic brackets and resulting shape of an orthodontic archwire, are obtained from the simulation of tooth movement to the target situation and the placement position of virtual brackets. The treatment planning can also be executed remotely by a precision appliance service center having access to the virtual model of the dentition.
