Abstract: Techniques that provide source metadata associated with code recommendations generated by an automation controller are described. A training data set comprising queries, code recommendations and source metadata associated with each of the code recommendations may be stripped of the source metadata and encoded by an NLP model to generate vector representations of each code recommendation. Each vector representation is stored in an index in association with the source metadata corresponding to the underlying code recommendation. In response to receiving a query, the query is processed using an inference model to generate a second code recommendation, which is encoded using the NLP model to generate a second vector representing the second code recommendation. The second vector is compared to the index to identify the source metadata corresponding to the second code recommendation. The second code recommendation and corresponding source metadata are provided via an interface of the automation controller.

Abstract: Surgical systems and methods involving a reamer tool and a surgical robotic arm. The reamer tool has a shaft, a tool engagement surface coupled to the shaft, and a reamer head attached to the shaft. The surgical robotic arm supports a guide that can receive the reamer tool. The guide has a pair of arms, each arm extending to an arm end and the arm ends being spaced apart from one another to provide an opening between the arm ends. A channel is formed between the arms. The guide enables a portion of the shaft to move through the opening between the arm ends such that the shaft portion can enter and exit the channel. The arms define a guide engagement surface that is arc-shaped and that enables contact with the tool engagement surface to facilitate alignment of the reamer tool and the guide.

Abstract: Surgical systems and methods involve a robotic manipulator with a force sensor and a surgical tool that holds a screw. The screw has a known thread geometry. A navigation system tracks a pose of a target anatomy. Controller(s) store the known thread geometry and control the robotic manipulator to maintain the rotational axis on a planned trajectory with respect to the target anatomy based on the tracked pose of the target anatomy. The controller(s) detect, with the force sensor, a force applied by a user. The controller(s) control a rotational rate of the surgical tool to rotate the screw about a rotational axis and an advancement rate of the surgical tool to linearly advance the screw along the planned trajectory. The rotational rate and the advancement rate are based on the force applied by the user and are proportional to the known thread geometry.

Abstract: A robotic system and methods for performing spine surgery are disclosed. The system comprises a robotic manipulator with a tool to hold a screw and to rotate the screw about a rotational axis. The screw is self-tapping and has a known thread geometry that is stored by one or more controllers. A navigation system tracks a position of a target anatomy. Movement of the robotic manipulator is controlled to maintain the rotational axis of the surgical tool along a planned trajectory with respect to the target anatomy based on the tracked position of the target anatomy. In autonomous or manual modes of operation, the rotational rate of the screw about the rotational axis and/or an advancement rate of the screw linearly along the planned trajectory is controlled to be proportional to the known thread geometry stored in the memory.

Abstract: The presently disclosed subject matter is directed to an anti-theft device for use with a motorized vehicle, such as a riding lawn mower. The device comprises a main body defined by first and second ends. Each end of the device comprises a pair of arms, each with a distal end and a proximal end. The distal end of each arm includes an aperture sized and shaped to allow a lock or other securing element to pass therethrough. For example, with riding lawn mowers, the disclosed device can be used to lock the mower handles in an “off” position, so that the mower cannot be started until the device is removed.
