Patent number: 11943537Abstract: A digital pathology scanning apparatus is configured to initiate a rescan of a portion of a sample responsive to detecting a mechanical vibration during image acquisition that exceeds a predetermined threshold. The digital pathology scanning apparatus includes a plurality of sensors and a processor that analyzes sensor data received during movement of a scanning stage supporting a sample during image acquisition. The processor is configured to identify a mechanical vibration imparted on the scanning stage during image acquisition and determine if the mechanical vibration exceeds a predetermined threshold. If the predetermined threshold is exceeded, the processor is configured to initiate a rescan of the portion of the sample being scanned at the time of the mechanical vibration.Type: GrantFiled: November 30, 2018Date of Patent: March 26, 2024Assignee: Leica Biosystems Imaging, Inc.Inventors: Nicholas Newberg, Prentash Djelosevic

Patent number: 11668725Abstract: A digital slide scanning apparatus slide rack carousel allows continuous loading and unloading of slide racks into the carousel while the digital slide scanning apparatus is simultaneously digitizing glass slides. The slide rack carousel includes a base having an interior portion of its upper surface at an angle. The slide rack carousel also includes plural rack spacers extending upward from the base and adjacent rack spacers define a rack slot. Each rack spacer also includes a rack stopper on each side such that adjacent rack spacers have rack stoppers facing each other. The rack stoppers prevent a slide rack from moving further toward the center of the carousel than desired.Type: GrantFiled: February 16, 2021Date of Patent: June 6, 2023Assignee: Leica Biosystems Imaging, Inc.Inventors: Nicholas Newberg, Prentash Djelosevic

Publication number: 20220349909Abstract: A stall detection system is provided that determines if a glass slide in motion during an automated process is at risk for being damaged and stops motion in the event of an unacceptable risk of damage. The system includes one or more motors configured to move a glass slide (directly or indirectly). The motors are configured to generate a load resistance value. The system includes one or more processors that monitor the load resistance value of a motor during motion and compares the load resistance value to a predetermined threshold resistance value to determine the risk of a glass slide being damaged. The predetermined threshold resistance value may correspond to a risk of slide breakage in response to a force applied to any surface of the slide, or a risk of losing a controlling grip on a slide rack, or a risk of a motor skipping a motor step.Type: ApplicationFiled: August 6, 2020Publication date: November 3, 2022Inventors: Nicholas Newberg, Prentash Djelosevic, Aaron Alan Stearrett

Publication number: 20220326494Abstract: Control processes for a slide-scanning system comprising a carousel with a plurality of rack slots configured to receive slide racks via an exposed portion of the scanning system. In an embodiment, initializing the scanning system comprises automatically homing back-end and front-end components, wherein the front-end components comprise the carousel. An inventory of all slide racks in the carousel is automatically generated. If any slide rack was being processed by any back-end components, the slide rack is automatically unloaded into a corresponding rack slot. In addition, the carousel is automatically positioned to expose a starting subset of the rack slots within the exposed portion. This starting subset may comprise a maximum segment of adjacent empty rack slots.Type: ApplicationFiled: August 5, 2020Publication date: October 13, 2022Inventors: Peyman NAJMABADI, Nicholas NEWBERG, Prentash DJELOSEVIC, Aaron STEARRETT

Patent number: 11446670Abstract: A digital slide scanning apparatus slide stage is configured to hold 1×3 and 2×3 glass slides. The slide stage is configured to alter its position by lateral shift or rotation to present the 1×3 or 2×3 sized recess to a slide rack for loading of the slide onto the stage. Also, a removable insert may configure the stage to hold a 1×3 glass slide when present and to hold a 2×3 glass slide when removed. Alternatively, a gripper stage is described herein that includes a fixed arm and a movable arm, each with one or more contact points configured to engage a side surface of the glass slide. Once the glass slide is secured between the contact points of the movable arm and the contact points of the fixed arm, the slide is further processed for scanning.Type: GrantFiled: August 17, 2018Date of Patent: September 20, 2022Assignee: Leica Biosystems Imaging, Inc.Inventors: Nick Newberg, Prentash Djelosevic

Patent number: 11445081Abstract: A slide rack determination system for a digital slide scanning apparatus. In an embodiment, a motor drives a slide rack at a known rate toward an engagement surface. The elapsed time until engagement may be used to detect the presence or absence of the slide rack and/or the height of the slide rack. In addition, one or more sensors may detect one or more features of the slide rack, and these feature(s) may be used to determine the presence or absence of a slide rack, whether usage of the slide rack is supported or unsupported by the digital slide scanning apparatus, the orientation of the slide rack, and/or the manufacturer and/or model of the slide rack.Type: GrantFiled: July 20, 2020Date of Patent: September 13, 2022Assignee: Leica Biosystems Imaging, Inc.Inventors: Nicholas Newberg, Prentash Djelosevic

Patent number: 11434082Abstract: A stuck slide determination system is provided that determines if a slide (e.g., glass slide), positioned on a scanning stage at the start of the scanning process, gets stuck and does not move along with the scanning stage after the scanning process commences. In an embodiment, the system includes a sensor having a transmitter and receiver that are relatively positioned to detect the presence of the stage or a slide or the absence of the stage or a slide. When the scanning stage begins to move at the start of the scanning process, a processor monitors a signal from the sensor and determines if the slide is improperly positioned after the scanning process has commenced. If the slide is improperly positioned, the processor stops movement of the scanning stage in order to protect the slide from damage.Type: GrantFiled: May 18, 2020Date of Patent: September 6, 2022Assignee: Leica Biosystems Imaging, Inc.Inventors: Nicholas Newberg, Prentash Djelosevic, Aaron Stearrett, Peyman Najmabadi
