Abstract: A surgical guide assembly having an attachment device configured to be coupled to a bone. A cut location indicator is coupled to the attachment device. The cut location indicator identifies a location where the bone is to be cut. An arm is coupled to the attachment device, the cut location indicator, or both. A support structure is coupled to the arm. The support structure is configured to have a trackable feature coupled thereto.

Abstract: A method for computer-assisted planning of a transplant surgery is provided.

Abstract: A work machine includes a frame; an engine supported by the frame; a plurality of ground engaging devices supporting the frame and driven by the engine; an operator cabin supported by the frame; a plurality of sensors and input devices configured to provide a plurality of signals; and a control module. The control module is configured to receive the plurality of signals from the plurality of sensors and input devices, determine if any of the plurality of signals is a positive signal, where a positive signal indicates that an operator is present in the machine, indicate an ‘operator present’ status if at least one of the plurality of signals remains positive for a debounce time, and indicate a ‘no operator present’ status if none of the plurality of signals remains positive for a threshold time.

Abstract: A computer-assisted surgical system can include a donor sub-system and a recipient sub-system. The donor sub-system includes a first reference unit having a first trackable element, a fragment reference unit having a second trackable element, and a first detector configured to provide at least one of a first signal corresponding to a detected location of one or more of the first trackable element and the second trackable element. The recipient sub-system includes a second reference unit having a third trackable element, and a second detector configured to provide at least one of a second signal corresponding to a detected location of at least the third trackable element.

Abstract: Disclosed is a method of simulating mastication. The method includes obtaining computer-readable three-dimensional representations of a first skeletal fragment including a portion of at least one of a mandible and a maxilla and of a recipient skeletal fragment including a portion of at least one of a mandible and a maxilla. The method also includes obtaining placement data and obtaining muscle insertion data. The method also includes simulating a contraction of a muscle positioned according to the muscle insertion data in a representation of a surgical hybrid comprising at least a portion of the first skeletal fragment positioned according to the placement data relative to at least a portion of the recipient skeletal fragment. The method also includes outputting a representation of mastication represented by the simulating.

Abstract: A rear frame for a motor grader includes a pair of arms that are disposed equidistantly from a mid-plane. Each arm has a front portion, a rear portion, and a mid-portion located between the front and rear portions. The front portion of each arm is configured to pivotally couple with a front frame of the motor grader. The rear frame also includes a ripper mounting arrangement, a bumper, and a torque resisting member. The ripper mounting arrangement is located at a rear end of the rear portion of each arm. The bumper is laterally disposed with respect to the mid-plane and rigidly attached to a position on the rear portion of each arm located adjacent the rear end of the rear portion of each arm. The torque resisting member is laterally disposed with respect to the mid-plane and rigidly attached to the mid-portion of each arm.

Abstract: Provided herein is a computer-implemented method, system, computer-readable medium operable to perform the method for cephalometry for orthognathic and craniomaxillofacial surgery. The method can include transforming a set of cephalometric landmarks from a donor or mobile skeletal fragment in a first reference frame to a second reference frame based on a registration process that maps coordinates from the first reference frame to coordinates in the second reference frame; tracking movement, based on one or more signals from one or more sensors, during surgery, of one or more of the cephalometric landmarks in the set of cephalometric landmarks associated with the donor or mobile skeletal fragment with respect to one or more of the cephalometric landmarks in the set of cephalometric landmarks associated with a recipient or second skeletal portion in the second reference frame; calculating one or more cephalometry metrics; and providing an update of the one or more cephalometry metrics.
