  • Patent number: 12334207
    Abstract: Methods and systems for establishing dental occlusion are described herein. These systems and methods can be used for 1-, 2-, or 3-piece maxillary orthognathic surgeries. An example computer-implemented method includes receiving a maxillary dental model and a mandibular dental model, identifying a plurality of dental landmarks in each of the maxillary and mandibular dental models, and extracting a plurality of points-of-interest from each of the maxillary and mandibular dental models. The dental landmarks include a plurality of maxillary dental landmarks and a plurality of mandibular dental landmarks. The method further includes aligning the maxillary and mandibular points-of-interest, and fine tuning the alignment of the maxillary and mandibular dental models to achieve maximum contact with a collision constraint.

  • Patent number: 11963832
    Abstract: Systems and methods for orthognathic surgical planning are described herein. An example computer-implemented method can include generating a composite three-dimensional (3D) model of a subject's skull, defining a primal reference frame for the composite 3D model, performing a cephalometric analysis on the composite 3D model to quantify at least one geometric property of the subject's skull, performing a virtual osteotomy to separate the composite 3D model into a plurality of segments, performing a surgical simulation using the osteotomized segments, and designing a surgical splint or template for the subject.

  • Patent number: 11474581
    Abstract: A hot-swap controller regulates the supply of power from an input node to a load coupled to an output node. The controller includes at least one limiting circuit configured to control a first switch connected between the input node and the load to limit an output current of the first switch for application to the load. A control logic circuit determines a state of the first switch and outputs a local state signal, and a communication circuit responsive to the local state signal establishes a voltage or current level corresponding to the local state at a communication circuit output. A communication terminal is also provided that is responsive to the communication output and that is adapted to connect to a second communication terminal of a second hot-swap controller to communicate the local state to the second hot-swap controller.

  • Publication number: 20220215625
    Abstract: Systems and methods for estimating a patient-specific reference bone shape model for a patient with craniomaxillofacial (CMF) defects are described herein. An example method includes receiving a twodimensional (ā€œ2Dā€) pre-trauma image of a subject, and generating a three-dimensional (ā€œ3Dā€) facial surface model for the subject from the 2D pre-trauma image. The method also includes providing a correlation model between 3D facial and bone surfaces, and estimating a reference bone model for the subject using the 3D facial surface model and the correlation model.

  • Patent number: 8306623
    Abstract: An implantable system acquires intracardiac impedance with an implantable lead system. In one implementation, the system generates frequency-rich, low energy, multi-phasic waveforms that provide a net-zero charge and a net-zero voltage. When applied to bodily tissues, current pulses or voltage pulses having the multi-phasic waveform provide increased specificity and sensitivity in probing tissue. The effects of the applied pulses are sensed as a corresponding waveform. The waveforms of the applied and sensed pulses can be integrated to obtain corresponding area values that represent the current and voltage across a spectrum of frequencies. These areas can be compared to obtain a reliable impedance value for the tissue. Frequency response, phase delay, and response to modulated pulse width can also be measured to determine a relative capacitance of the tissue, indicative of infarcted tissue, blood to tissue ratio, degree of edema, and other physiological parameters.
