Patent number: 12145146Abstract: Embodiments of lab automation workstations are disclosed in which the pod that performs pipetting operations is integrated with pipette tip-loading functionality. To generate the necessary tip-loading force, a dual drive system is used that is symmetric about the Y-axis to allow for offset or partial tip box loads by dynamically centering the drive force (e.g., the tip-loading force) over the reaction load. This minimizes the need for oversized linear motion components while still allowing for the generation of high tip-loading forces needed to properly load a large number of pipette tips simultaneously.Type: GrantFiled: November 21, 2022Date of Patent: November 19, 2024Assignee: Beckman Coulter, Inc.Inventors: Matthew S. Davis, Ronald Douglas Johnson, Mark A. Nierzwick, Craig A. Hudson, Charles M. Neese, Mark F. Sauerburger, John S. Snider

Patent number: 12140497Abstract: Conformance testing of a rebuilt motor includes disposing a motor under test in a motor test stand, coupling a plurality of sensors to the motor under test including a first vibrational sensor to the motor under test; a first temperature sensor to the motor under test; a first rotational speed sensor to the motor under test. A set of test parameters are received comprising parameters for a conformance test, the test parameters including a vibrational sensor parameter, a temperature sensor parameter, and a rotational speed parameter. A motor under test is placed in an on-state and a processing device receives sensor data simultaneously from the sensors, determines that the rotational speed satisfies the rotational speed parameter, and stores time sampled sensor data received from the plurality of sensors relative to a time zero corresponding to a time when the rotational speed satisfies the rotational speed.Type: GrantFiled: October 26, 2022Date of Patent: November 12, 2024Assignee: AKTIEBOLAGET SKFInventors: Douglas Johnson, Michael Ingram, Greg Ziegler, Soenke Petersen
