Abstract: A surgical tool comprising a drive housing having first and second ends, a lead screw extending between the first and second ends and rotatably coupled to the first end at a drive input, a carriage mounted to the lead screw at a carriage nut and movable within the drive housing between the first and second ends, and an instrument driver arranged at an end of a robotic arm and matable with the first end. A drive output is matable with the drive input such that rotation of the drive output correspondingly rotates the drive input and the lead screw to thereby translate the carriage nut along the lead screw. A fin may be connected to the carriage and accessible by a user from an exterior of the drive housing to manually translate the carriage along the lead screw and thereby backdrive the drive output.

Abstract: A control device receives, from an engine load sensor device, a value of an engine load of an engine of an equipment operating in an operating environment. The control device compares the value of the engine load to a target engine load range defined by a minimum target engine load value and a maximum target engine load value. Responsive to determining that the value of the engine load is less than the minimum target engine load value, the control device lowers a cutting blade of the equipment to increase an engagement of the cutting blade with a surface or subsurface. Responsive to determining that the engine load is greater than the maximum target engine load value, the control device raises the cutting blade of the equipment to decrease the engagement of the cutting blade with the surface or subsurface.

Abstract: Described herein are systems, methods, and other techniques for controlling a velocity of a construction machine operating within a construction site. Sensor data is captured using one or more sensors of the construction machine while the construction machine is moving at the velocity in a forward or a backward direction. An actual surface of the construction site is estimated based on the sensor data. A deviation between a target surface and the actual surface is calculated. An actual performance metric is calculated based on the deviation. The actual performance metric is compared to a target performance metric to determine a velocity adjustment. The velocity of the construction machine is adjusted by the velocity adjustment.

Abstract: A system for treating an eye includes a laser light source providing photoactivating light. The system includes a scanning system to receive the photoactivating light as a laser beam and to move the laser beam over a cornea treated with a cross-linking agent. The system includes a controller that provides control signal(s) to programmatically control the laser light source and the scanning system. The control signal(s) cause the laser beam to visit region(s) of the cornea more than once according to a scan pattern and expose the region(s) to the photoactivating light. The photoactivating light causes the cross-linking agent in the exposed region(s) to react with oxygen to generate cross-linking activity in the exposed region(s). The scan pattern causes a predetermined period of time to pass between visits by the laser beam to the exposed region(s), the predetermined period of time allowing oxygen in the exposed region(s) to replenish.

Abstract: A lumen inspection device includes an elongate member and a sealing member at a distal end of the elongate member. The elongate member is inserted into a lumen of a medical instrument. The lumen inspection device is translated along the lumen. The sealing member resiliently bears against a sidewall of the lumen as the lumen inspection device is translated along the lumen of the medical instrument. A pressure source is activated to pressurize a region of the lumen adjacent to the sealing member. A fluid property of the lumen is monitored to detect whether the sealing member deforms in response to an obstruction in the lumen.

Abstract: A method of drawing aquatic or other animal life in a fish-style tank to a clear side of the tank by providing a shelter structure affixed to an interior wall of the tank that encourages that life to enter by offering protection. The shelter structure does not obstruct people from viewing the fish from outside the tank. Treatments to the walls of the shelter can alter the opacity, color, appearance, shape and other aspects to increase the attractiveness of the shelter to the fish (or other animal), affect the behavior of the fish and provide ornamentation.

Abstract: Described herein are systems, methods, and other techniques for controlling a velocity of an implement-equipped machine. An actual position of the implement-equipped machine is estimated based on sensor data captured using the machine's sensors. A cross track error between a target position and the actual position is calculated. An actual cross track error metric is calculated based on the cross track error. The actual cross track error metric is compared to a target cross track error metric to determine a velocity adjustment, where the velocity adjustment is determined so as to reduce a difference between the actual cross track error metric and the target cross track error metric. The velocity of the implement-equipped machine is adjusted by the velocity adjustment.
