摘要： A drive system includes a linear actuator with a drive shaft and having an actuation axis extending along a length of the linear actuator. A motor assembly of the drive system couples to drive shaft and is configured to rotate the drive shaft about the actuation axis of the linear actuator. The drive system further includes a nut attached to the drive shaft and a carrier housing the nut. A linkage system of the drive system extends from a proximal end away from the motor assembly to a distal end. The proximal end of the linkage system rotatably attaches to the carrier at a first proximal attachment location where the first proximal attachment location offset is from the actuation axis. The drive system also includes an output link rotatably coupled to the distal end of the linkage system where the output link is offset from the actuation axis.

摘要： A method and apparatus to create water vapor supersaturation and particulate counts from an air sample. The method and apparatus include introducing an air sample into a chamber connected to an optical detector and an outlet by pumping at the outlet. The method further includes passing air through the chamber and optical detector in a steady flow, and subsequently closing the inlet while continuing the pumping to expand the air sample and exhaust a portion of the air sample through the optical detector. The walls of the particle chamber are wetted with a fluid such as water, and one portion of the wall is warmer than the other portions such that there is some condensational growth prior to the expansion, and yet more condensational growth during the expansion. The cycles are repeated by continuously repeating the introducing, passing and closing.

摘要： A dynamic planning controller receives a maneuver for a robot and a current state of the robot and transforms the maneuver and the current state of the robot into a nonlinear optimization problem. The nonlinear optimization problem is configured to optimize an unknown force and an unknown position vector. At a first time instance, the controller linearizes the nonlinear optimization problem into a first linear optimization problem and determines a first solution to the first linear optimization problem using quadratic programming. At a second time instance, the controller linearizes the nonlinear optimization problem into a second linear optimization problem based on the first solution at the first time instance and determines a second solution to the second linear optimization problem based on the first solution using the quadratic programming. The controller also generates a joint command to control motion of the robot during the maneuver based on the second solution.

摘要： Provided herein are methods of producing an RPE cell population from a starting cell suspension, such as a single cell suspension, of pluripotent stem cells (PSCs). Such a method may comprise culturing the starting single cell suspension of PSCs in differentiation media to produce human RPE cells.

摘要： A method of modeling a turbine mounted behind an aircraft wing for providing a specified proportion of a propulsive force in the aircraft flight direction to an amount of power generated by the turbine when driven by the airflow trailing the wings. The turbine converts a portion of the otherwise wasted energy in the rotational vortices trailing the aircraft wings into thrust that reduces aircraft drag while also providing electricity to power electrical systems on the aircraft. The method is also capable of modeling a turbine construction that will use the energy in the wake solely to generate electricity without increasing drag on the aircraft or solely to reduce drag without generating electricity. In one embodiment, the method saves computation time by using a recursive routine to define a preliminary turbine configuration based on an idealized vortex model and then matches it to the flow trailing an actual aircraft wing.

摘要： A method includes receiving sensor data for an environment about the robot. The sensor data is captured by one or more sensors of the robot. The method includes detecting one or more objects in the environment using the received sensor data. For each detected object, the method includes authoring an interaction behavior indicating a behavior that the robot is capable of performing with respect to the corresponding detected object. The method also includes augmenting a localization map of the environment to reflect the respective interaction behavior of each detected object.

摘要： A connecting mechanism includes a first section and a second section engageable with the first section. The second section includes a locking assembly configured to engage a stud with a roller bearing in the first section. That is, the locking assembly is actuatable between a locked state configured to lock the first section to the second section when the first and second sections are engaged and an unlocked state configured to allow the second section to engage with or disengage from the first section. The locking assembly includes a linkage arm engaging a handle and a wedge having a tapered section. The handle is actuatable between a locked position configured to place the locking assembly in the locked state by advancing the tapered section of the wedge and an unlocked position configured to place the locking assembly in the unlocked state by retracting the tapered section of the wedge.
