  • Publication number: 20220268673
    Abstract: At least some embodiments of the technology are directed to an automated slide processing apparatus configured to apply at least one reagent to a specimen carried by a microscope slide. The slide processing station can include a support element with a support surface, at least one vacuum port, and a sealing member having a non-round shape. In an uncompressed state, the scaling member can extend upwardly beyond the support surface. In a compressed state, the scaling member can be configured to maintain an airtight seal with a backside of the microscope slide as the microscope slide is pulled against the support surface by a vacuum drawn via the at least one vacuum port.

  • Publication number: 20210293672
    Abstract: The disclosure presents systems and methods for processing a specimen slide using a specimen processing system. Specimen slides may sequentially be ejected from a slide carrier towards a label reader to determine an appropriate processing protocol for the slides. A cracking element may be engaged with the slide carrier prior to ejecting the slide, in order to break or “crack” any residual adhesive bond between edges of a slide and walls of the carrier. The specimen slides may be horizontally aligned and resting on a corresponding plurality of flat shelves, enabling even spacing via gravitational forces. The slides are therefore evenly spaced, enabling damage-free ejection of slides, and proper positioning for additional operations including scanning, viewing, heating, washing, and other processing.

  • Publication number: 20210270857
    Abstract: Systems and methods that enable automated processing of specimens carried on microscope slides are described herein. In some embodiments, the system can include, for example, a slide ejector assembly having a slide staging device configured to receive a slide and an over-travel inhibitor that includes a first vacuum port positioned to draw a first vacuum between the slide and a standby platform as the slide is moved across at least a portion of the standby platform. The over-travel inhibitor includes a first sensor for detecting a presence of the slide on the standby platform. The system can also include a transfer assembly to transport slides away from the slide ejector assembly. The transfer assembly can include a floating transfer head having a vacuum port for drawing a partial vacuum for holding the slide.

  • Patent number: 7163170
    Abstract: An apparatus and method for controlling the movement of an elevator mechanism in a tape drive system. The mechanism of the present invention employs a tachometer to detect the magnetic decoupling of a cartridge from a cartridge reel motor. A holding torque is placed on the cartridge reel motor. A voltage or current ramp is supplied to the elevator mechanism, wherein the elevator mechanism raises and magnetically decouples the tape cartridge from the cartridge reel motor. As the coupling force is broken, the torque placed on the cartridge reel motor causes the motor to turn. The tachometer detects the magnetic decoupling of the cartridge from the cartridge reel motor by sensing the angular displacement of the motor. In response, the controller decreases the voltage or current ramp to adapt to the load reduction on the elevator mechanism, and thereby more smoothly continue the elevator motion.
