  • Patent number: 11761172
    Abstract: Systems and methods for compensating dipper swing control. One method includes, with at least one processor, determining a direction of compensation opposite a current swing direction of the dipper and applying the maximum available swing torque in the direction of compensation when an acceleration of the dipper is greater than a predetermined acceleration value. The method can also include determining a current state of the shovel and performing the above steps when the current state of the shovel is a swing-to-truck state or a return-to-tuck state. When the current state of the shovel is a dig-state, the method can include limiting the maximum available swing torque and allowing, with the at least one processor, swing torque to ramp up to the maximum available swing torque over a predetermined period of time when dipper is retracted to a predetermined crowd position.

  • Patent number: 11021851
    Abstract: A mining machine having a control system for operating the mining machine. The control system includes a vibration monitor. The mining machine further includes a sensor and a vibration control system. The sensor senses vibration of a component of the mining machine. The vibration control system determines when the mining machine is moving in a proper cycle, triggers acquisition of vibration sensor data from the sensor in response to determining that the mining machine is moving in the proper cycle, and outputs the vibration sensor data.

  • Patent number: 9754764
    Abstract: A method and apparatus for aligning a laser beam coincident with a charged particle beam. The invention described provides a method for aligning the laser beam through the center of an objective lens and ultimately targeting the eucentric point of a multi-beam system. The apparatus takes advantage of components of the laser beam alignment system being positioned within and outside of the vacuum chamber of the charged particle system.

  • Patent number: 9679741
    Abstract: An environmental cell for a charged particle beam system allows relative motion between the cell mounted on an X-Y stage and the optical axis of the focusing column, thereby eliminating the need for a sub-stage within the cell. A flexible cell configuration, such as a retractable lid, permits a variety of processes, including beam-induced and thermally-induced processes. Photoelectron yield spectroscopy performed in a charged particle beam system and using gas cascade amplification of the photoelectrons allows analysis of material in the cell and monitoring of processing in the cell. Luminescence analysis can be also performed using a retractable mirror.
