Abstract: The invention provides a plurality of methods which may be employed as a single method or a plurality of sequential method steps in the isolation and purification of Cannabidiol from Hemp plants. It also provides methods for having a terpene-rich fraction as a byproduct of the method. Depending upon the ultimate objective, the individual method components may be used separately or combined with one or more method steps to accomplish the objectives.

Abstract: A system for tissue suturing guidance in a surgical site includes an imaging device configured to capture an image of a surgical needle within the surgical site and an imaging device control unit configured to control the imaging device. The imaging device control unit includes a processor and a memory.

Abstract: A surgical robotic system includes an image processing device configured to receive a stereoscopic video feed and output a depth map. The image processing device may process the stereoscopic video feed through two different depth mapping algorithms concurrently and to compare the output of each of the algorithms (i.e., two depth maps) to determine whether the output of one of the algorithms is accurate.

Abstract: Provided is a crude oil additive comprising a pyrolysis oil fraction. In some embodiments, the crude oil additive further comprises a dispersant. Also provided are methods of preparing the crude oil additive as well as methods for reducing the viscosity of crude oil and methods for increasing the API gravity of crude oil.

Abstract: A surgical robotic system includes an image processing device configured to receive an endoscopic video feed and generate a stereoscopic video feed with confidence shading overlays on display. The confidence shading is based on a level of confidence associated with uncertain regions within images making up the stereoscopic video feed.

Abstract: A robotic surgical system includes a robot system, a user interface, a hand detection system, and a processing unit. The robot system includes a tool coupled to an arm. The user interface includes a handle assembly including a body portion having a proximal end portion, and a first actuator movable between open and closed positions. The hand detection system includes a first sensor disposed within the first actuator for detecting finger presence on the first actuator, a second sensor disposed on the proximal end portion for detecting palm presence about the proximal end portion, and an encoder disposed within the body portion for detecting position of the first actuator relative to the body portion. The processing unit is electrically coupled to the first, second, and third sensors for receiving and processing data from the first, second, and third sensors.

Abstract: ( robotic surgical system with user engagement monitoring includes a surgeon console having a hand detection system and a tracking device including an image capture device configured to capture an image of a user position reference point, wherein information from the hand detection system and the tracking device are combined to control operation of the robotic surgical system.
