Abstract: Systems and methods for identifying tooth keypoints are disclosed. A method includes receiving digital representations comprising patient teeth, and identifying a first tooth outline from a first digital representation and a second tooth outline from a second digital representation. The method includes retrieving a 3D mesh comprising model teeth. The method includes projecting a first mesh boundary onto a patient tooth and modifying the first mesh boundary to match the first tooth outline. The method includes identifying a first tooth point on the first tooth outline that corresponds with a first mesh point on the first mesh boundary. The method includes mapping the first tooth point to the 3D mesh. The method includes determining that the first and second tooth points correspond to a common 3D mesh point. The method includes designating the first tooth point as a keypoint. The method includes modifying a digital representation based on the keypoint.

Abstract: Systems and methods for identifying tooth correspondences are disclosed. A method includes receiving a digital representation including patient teeth, and identifying a tooth outline from the digital representation. The method includes retrieving a 3D mesh including model teeth. The method includes projecting a first mesh boundary onto a patient tooth and modifying the first projected mesh boundary to match the first tooth outline. The method includes identifying a first tooth point on the first tooth outline that corresponds with a first mesh point on the first projected mesh boundary. The method includes mapping the first tooth point to the 3D mesh. The method includes determining that the first and second tooth points correspond to a common 3D mesh point. The method includes modifying at least one of the digital representation or the 3D mesh based on determining the tooth points correspond to the common 3D mesh point.

Abstract: A prosthetic heart valve includes an inner frame having a longitudinal axis, a plurality of prosthetic leaflets coupled to the inner frame, the plurality of prosthetic leaflets configured to allow blood to flow through the inner frame in an antegrade direction along the longitudinal axis and to substantially block blood from flowing through the inner frame in a retrograde direction along the longitudinal axis, an outer frame connected to the inner frame, and a sealing feature coupled to the inner frame at a coupling point and extending partially, but not completely, between the coupling point and a point of the outer frame that is radially outward of the coupling point in a direction substantially orthogonal to the longitudinal axis, and wherein in an implanted condition, the sealing feature is positioned such that backpressure from ventricular systole acts on the sealing feature.

Abstract: A method of operating an exoskeleton system that includes obtaining a first set of sensor data from one or more sensors associated with one or more leg actuator units of an exoskeleton system during a user activity, the first set of sensor data indicating a first configuration state of the one or more actuator units; determining, based at least in part on the first set of obtained sensor data, to change configuration of the one or more leg actuator units to a second configuration state to support a user during the user activity; and introducing fluid to one or more fluidic actuators of the one or more leg actuator units to generate the second configuration state by causing the one or more fluidic actuators to apply force at the one or more actuator units.

Abstract: A method and apparatus of filing beverage combines pressurized beverage delivery (rather than gravity feed) with variable pressure control of the gas flow from the can during snift. By modulating beverage flow and especially pressure, it is possible to saturate a beverage, or optionally fill a can's widget with gas with a shorter set of fill steps. In addition, the speed of beverage filling can be dramatically increased compared to small scale systems normally used. Unlike known large scale pressure systems, the beverage bowl may be located beneath the rest of the apparatus and modulated pressure may be used, making for a smaller and more portable unit.

Abstract: A method and apparatus of filing beverage combines pressurized beverage delivery (rather than gravity feed) with variable pressure control of the beverage flow into the can. By modulating beverage flow and especially beverage pressure, it is possible to fill a can's widget (gas reservoir) with gas with a shorter set of fill steps. In addition, the speed of beverage filling can be dramatically increased compared to small scale systems normally used. Unlike known large scale pressure systems, the beverage bowl may be located beneath the rest of the apparatus and modulated pressure may be used, making for a smaller and more portable unit.

Abstract: An exoskeleton system having an actuator unit configured to be coupled to a leg of a user. The actuator unit includes an upper arm and a lower arm that are rotatably coupled via a joint, the joint positioned at a knee of the user with the upper arm coupled about an upper leg portion of the user above the knee and with the lower arm coupled about a lower leg portion of the user below the knee; a fluidic actuator that extends between the upper arm and lower arm; and one or more fluid lines coupled to the fluidic actuator to introduce fluid to the fluidic actuator that causes force to be applied to the upper arm and lower arm.

Abstract: The present concrete crack repair device (CCRD) can be comprised of two nodules connected by an elongated strip wherein the elongated strip can be narrower than the nodules in at least one plane. Both the elongated strip and the nodules can comprise carbon fibers wherein most of the carbon fibers are located within the same plane maximizing the tensile strength of the device. Installation of the CCRD can be performed by drilling holes into the surface of the concrete on either side of the crack and cutting a slot in the surface of the concrete between the two holes, or adding the holes after the slot has been cut, wherein the slot and holes are located in a line that is roughly perpendicular to the crack. The CCRD can then be installed by placing each nodule in a hole and the elongated strip within the slot.

Abstract: A continuous motion position controlled in-line linear seamer allows a manufacturer or brewery such as a microbrewery to have high speed can seaming (attachment of lids to full cans of beverage) with a single compact, inexpensive, independent and repositionable seaming machine. The seaming is carried out in-line with production, and is done using a linear can path with no need for a large carousel. The motion is continuous because a variable pitch worm drive is constantly operating, driving cans at different speeds for different portions of the can path, including one portion of the path at which the can may remain motionless while being seamed.

The first exoskeleton collects first data and transmits the first data to the central server or peripheral device. The central server or peripheral device generates second data using the first data and transmits the second data to the first exoskeleton or a second exoskeleton.
