  • Publication number: 20200293015
    Abstract: Systems, methods, and apparatus are disclosed for machining a part. Methods include generating a first spatial representation identifying a first orientation of a machining tool, and mechanically coupling an end effector to the part at a first position, the end effector including the machining tool and a coupling tool. Methods include generating a second spatial representation identifying a second orientation of the machining tool relative to the part, the first and second spatial representations being generated based on images captured by at least one imaging device and measurements from a plurality of sensors. Methods include identifying a plurality of differences that result from the coupling and that include a rotational distance and translational distance, the identifying being based on a comparison of a first image and a second image. Methods include adjusting the machining tool to return the machining tool to the first orientation at the first position.

  • Publication number: 20200198701
    Abstract: A vehicle system includes a steering wheel configured to output an output based on an input from a user, and a controller configured to: determine a target orientation of front wheels of a vehicle based on vehicle environment information, determine whether an orientation of the front wheels of the vehicle based on the output from the steering wheel deviates from the target orientation, disengage the steering wheel from the front wheels in response to determination that the orientation of the front wheels deviates from the target orientation, adjust the orientation of the front wheels to the target orientation and provide a feedback in response to adjusting the orientation of the front wheels to the target orientation.

  • Patent number: 10691097
    Abstract: Systems, methods, and apparatus are disclosed for machining a part. The methods may include generating a plurality of spatial representations associated with a plurality of positions identified by a machining pattern associated with the part. The plurality of spatial representations may include a first spatial representation identifying a first orientation of a machining tool relative to the part at a first position. The methods may include moving an end effector to the first position. The methods may include mechanically coupling, using a coupling tool, the end effector to the part at the first position. The methods may include generating a second spatial representation identifying a second orientation of the machining tool relative to the part at the first position. The methods may include adjusting the machining tool in response to determining that the second spatial representation is different than the first spatial representation.

  • Patent number: 10646930
    Abstract: A system and method is disclosed for performing matched drilling operations on mating first and second workpieces. A microscopic camera is mounted on a movable spindle holding a tool. A micro-adjustment mechanism on the spindle controllable moves the tool. A template is provided that is mounted to the first workpiece and to the second workpiece. A controller receives images of the template from the microscopic camera at each of the predetermined positions on the first workpiece and identifies microscopic features on the template associated with each of the predetermined positions on the first workpiece. The controller compares microscopic features within received images of the template at each of the predetermined positions on the second workpiece associated with microscopic features of a corresponding image of the first workpiece to calculate a necessary offset adjustment that is applied to the micro-adjustment mechanism before each operation on the second workpiece.

  • Patent number: 10633025
    Abstract: A vehicle system for operating a vehicle is provided. The vehicle system includes a first output device configured to output a first output, and a second output device configured to output a second output. The vehicle system operates the vehicle based on the first output from the first output device while obtaining vehicle environment information, determines whether an autonomous take-over event occurs based on the vehicle environment information, operates the vehicle in an autonomous driving mode in response to determining that the autonomous takeover event occurred, determines whether the vehicle system receives a take-over signal from the second output device, and operates the vehicle based on the second output from the second output device in response to determining that the vehicle system received the take-over signal from the second output device.

  • Patent number: 10207787
    Abstract: A method for drawing a flexible sleeve over an elongated mandrel includes placing a ring within a lumen of the sleeve. A first end of the sleeve is fixed against movement relative to a first end of the mandrel. A first end portion of the sleeve is inverted over a first end portion of the mandrel so as to define a circumferential cuff in the sleeve, and the ring is positioned concentrically within the circumferential cuff. Using, e.g., a magnet, the ring is then urged longitudinally along the mandrel and toward an opposite, second end thereof, such that the sleeve is inverted over at least an outer surface of the mandrel.

  • Patent number: 8247319
    Abstract: Techniques for silicide, germanide or germanosilicide formation in extremely small structures are provided. In one aspect, a method for forming a silicide, germanide or germanosilicide in a three-dimensional silicon, germanium or silicon germanium structure having extremely small dimensions is provided.
