  • Publication number: 20230278239
    Abstract: A ground simulation device and method for an on-orbit manipulation of a space manipulator is provided. The ground simulation device includes: a dual-arm robot, configured to simulate the space manipulator operating a target object; a suspension device, including a fixed post and passive rods, where the passive rods are movably connected with a top end of the fixed post, and the target object is suspended to the passive rods; and a simulation platform, configured to fix the dual-arm robot and the suspension device thereon. The ground simulation device provides the passive rods on the suspension device and suspends the target object to the passive rods, thus overcoming the gravity of the target object. In addition, the passive rods can drive the target object to move under an influence of an external force, achieving a similar suspension effect to that in space, and providing a desired, safe, and reliable implementation effect.

  • Patent number: 11662682
    Abstract: Various embodiments disclose a method of detecting a media jam in a printer. The method includes causing a sensor unit of the printer to generate a sensor signal indicative of a reflectance characteristic associated with a surface of a roller of the printer. Further, the method includes receiving the sensor signal from the sensor unit of the printer and comparing the reflectance characteristic to a threshold reflectance characteristic associated with the roller. Furthermore, in response to the comparison, the method includes generating an output signal to indicate whether the media jam has occurred. For example, a first output signal indicates unsuccessful passage of a media along a media path of the printer, when the reflectance characteristic exceeds the threshold reflectance characteristic and a second output signal indicates successful passage of the media along the media path, when the reflectance characteristic is equal to or below the threshold reflectance characteristic.
