Abstract: Methods and systems are provided for personalizing foreign language instruction. In particular, the systems and methods provided apply artificial intelligence to novel tasks related to teaching foreign languages such as detecting skill levels of users, generating personalized course curriculums for individual users based on the learning goals and initial skill level of a user, generating custom assignment assets for those goals based on current strengths, weakness, generating content for custom questions for those assignment assets, and dynamically tracking and updating the skill level of the user during the course.

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.

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.

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.

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.
