  • Patent number: 11908452
    Abstract: Techniques for presenting an alternative input representation to a user for testing and collecting processing data are described. A system may determine that a received spoken input triggers an alternative input representation for presenting. The system may output data corresponding to the alternative input representation in response to the received spoken input, and the system may receive user feedback from the user. The system may store the user feedback and processing data corresponding to processing of the alternative input representation, which may be later used to update an alternative input component configured to determine alternative input representations for spoken inputs.

  • Patent number: 11830701
    Abstract: Systems and methods are provided for evacuating a chamber 101. The evacuation system comprises a cooler 320 coupled with the chamber and a controller 350. The controller is configured to determine whether a property of the cooler or the chamber satisfies one or more conditions. Based on the determination that the property satisfies the one or more conditions, the controller is configured to isolate the cooler from the chamber or control the temperature of the cooler to increase at one or more rates. The controller is further configured to control one or more pumps 330,340 to pump the chamber to a base pressure value.

  • Patent number: 11127618
    Abstract: Systems and methods are provided for dynamically compensating position errors of a sample. The system can comprise one or more sensing units configured to generate a signal based on a position of a sample and a controller. The controller can be configured to determine the position of the sample based on the signal and in response to the determined position, provide information associated with the determined position for control of one of a first handling unit in a first chamber, a second handling unit in a second chamber, and a beam location unit in the second chamber.
