  • Patent number: 10913158
    Abstract: A robotic system includes a robotic arm, a base couple coupled to the robotic arm, and a controller. The robotic supports a work implement and is configured to move the work implement to perform an operation on a workpiece. The base is configured to be removably coupled to a mounting surface. The controller is in communication with the robotic arm, the work implement, and the base. Further, the controller is configured to disable the operation of at least one of the robotic arm and the work implement if a coupling parameter between the base and the mounting surface is below a threshold value.

  • Publication number: 20190120013
    Abstract: A valve for limiting differential pressure applied to a downhole tool includes a housing and a movable piston/mandrel assembly therein. In a closed position, drilling mud or other fluid may be communicated through a central bore of the valve to the tool. When the differential pressure between the central bore and the wellbore exceeds a first predetermined value, the piston/mandrel assembly moves from a first position obstructing one or more relief ports to a second position not obstructing them, thereby providing a fluid path from the central bore of the valve to the wellbore bypassing the tool and relieving the differential pressure thereacross. When the differential pressure decreases to less than another preselected value, the piston/mandrel assembly returns to its original position again obstructing the relief ports. A trigger mechanism is provided to allow more precise control and separation of the preselected differential pressure values.

  • Publication number: 20180373143
    Abstract: The present disclosure relates to novel positive and negative photoresist compositions containing components that are based on one or more specific metals, metal salts, and/or metal complexes and methods of using them. The photoresist compositions and the methods are ideal for high speed, fine pattern processing using, for example, ultraviolet radiation, extreme ultraviolet radiation, beyond extreme ultraviolet radiation, X-rays, electron beam and other charged particle rays. The metals are characterized by high absorption cross sections and selected elastic and inelastic electron cross section.

  • Patent number: 10095112
    Abstract: The present disclosure relates to novel multiple trigger negative working photoresist compositions and processes. The processes involve removing acid-labile protecting groups from crosslinking functionalities in a first step and crosslinking the crosslinking functionality with an acid sensitive crosslinker in a second step. The incorporation of a multiple trigger pathway in the resist catalytic chain increases the chemical gradient in areas receiving a low dose of irradiation, effectively acting as a built in dose depend quencher-analog and thus enhancing chemical gradient and thus resolution, resolution blur and exposure latitude. The photoresist compositions and the methods are ideal for fine pattern processing using, for example, ultraviolet radiation, beyond extreme ultraviolet radiation, extreme ultraviolet radiation, X-rays and charged particle rays.

  • Publication number: 20160165843
    Abstract: An impact action cat toy with a rigid tube, an elastic cord, an elastic cord retainer, an elastic and non elastic cord retainer and a cat toy play member. The elastic cord is retained inside the rigid tube. The elastic cord terminates on one side in the elastic cord retaining member and on the opposite side in the elastic and non-elastic cord retaining member. The non elastic cord terminates on one side in the elastic and non elastic cord retaining member and on the opposite side in the cat toy play member. The cat toy play member is caused to quickly and erratically fly into the air while tethered on the non elastic cord when a user holds onto the rigid tube with one hand and stretches the elastic cord member from the elastic and non elastic cord retaining member with the other hand and releases the retaining member causing it to snap back and impact the end of the rigid tube.
