Abstract

The invention is directed to a biological scanner for scanning biological growth plates. A biological growth plate can be loaded into the biological scanner. Upon loading of a biological growth plate, the biological scanner generates an image of the plate and may perform an analysis of the image. Various embodiments are directed to loading features that facilitate automated loading and proper positioning of a plate within the biological scanner, and ejection features that facilitate the automated ejection of the plate from the scanner. Additional embodiments are directed to features that allow a scanner unit of the biological scanner to be attached to a mounting platform of the scanner in different possible configurations.

Claims

1. A biological scanner for scanning biological growth plates, the scanner comprising:

a scanner unit configured to receive a biological growth plate to be scanned, wherein the scanner unit houses an imaging device and a processor and is configured to scan the biological growth plate, the imaging device being configured to generate an image of the plate and the processor being configured to count biological agents in the plate based on the image; and

a mounting platform configured to eject the biological growth plate after the plate has been scanned, wherein the scanner unit is configured to be positioned on the mounting platform in a plurality of different possible positions.

4. The biological scanner of claim 1, wherein the scanner unit includes a drawer that opens to receive the plate and closes to move the plate into the scanner and wherein the mounting platform includes a conveyor configured to eject the plate from a slot in the mounting platform such that after the plate is received and scanned and the drawer is re-opened, the plate falls onto the conveyor, wherein when the scanner unit and the mounting platform are coupled to one another in a first position, the drawer and the slot are positioned along a common side of the scanner, and when the scanner unit and the mounting platform are coupled to one another in a second position, the drawer and the slot are not positioned along a common side of the scanner.

6. The biological scanner of claim 1, wherein the scanner unit defines a plurality of pins that mate with a plurality of sockets in the mounting platform, wherein a first pin mates with a first socket when the scanner unit and the mounting platform are coupled to one another in a first position and wherein the first pin mates with a second socket when the scanner unit and the mounting platform are coupled to one another in a second position.

7. The biological scanner of claim 1, wherein the mounting platform defines a plurality of pins that mate with a plurality of sockets in the scanner unit, wherein a first pin mates with a first socket when the scanner unit and the mounting platform are coupled to one another in a first position and wherein the first pin mates with a second socket when the scanner unit end the mounting platform are coupled to one another in a second position.

8. The biological scanner of claim 1, further comprising:

a drawer formed in the scanner unit that opens to receive the biological growth plate and closes to move the plate into the scanner;

a platen inside the scanner unit, wherein the plate is positioned adjacent the platen when the drawer is closed to move the plate into the scanner;

an apparatus inside the scanner unit that temporarily holds the plate adjacent the platen when the drawer is subsequently opened following movement of the plate into the scanner and releases the plate into the mounting platform following the subsequent opening of the drawer;

a conveyor inside the mounting platform that removes the plate from the mounting platform via a slot in the mounting platform following release of the plate by the apparatus when the drawer is subsequently opened.

2. A biological scanner for scanning biological growth plates, the scanner comprising:

a scanner unit configured to receive a biological growth plate to be scanned, wherein the scanner unit includes a drawer that opens to receive the plate and closes to move the plate into the scanner unit; and

a mounting platform configured to eject the biological growth plate after the plate has been scanned, wherein the scanner unit is configured to be positioned on the mounting platform in a plurality of different possible positions.

3. A biological scanner for scanning biological growth plates, the scanner comprising:

a scanner unit configured to receive a biological growth plate to be scanned; and

a mounting platform configured to eject the biological growth plate after the plate has been scanned, wherein the scanner unit is configured to be positioned on the mounting platform in a plurality of different possible positions, wherein the mounting platform includes a conveyor to eject the plate from a slot in the mounting platform.

5. A biological scanner for scanning biological growth plates, the scanner comprising:

a scanner unit configured to receive a biological growth plate to be scanned; and

a mounting platform configured to elect the biological growth plate after the plate has been scanned, wherein the scanner unit is configured to be positioned on the mounting platform in a plurality of different possible positions, and wherein at least one of the scanner unit and the mounting platform includes a plurality of electrical interfaces and the scanner unit and the mounting platform can be electrically coupled to one another via one or more of the electrical interfaces in the plurality of different possible positions relative to one another.

9. A method comprising:

attaching a scanner unit of a biological scanner to a mounting platform of the biological scanner, the scanner unit being configured to receive a biological growth plate and the mounting platform being configured to eject the biological growth plate removing the scanner unit from the mounting platform; and

reattaching the scanner unit to the mounting platform in a different position relative to the mounting platform.

10. The method of claim 9, further comprising counting a number of biological agents in the biological growth plate when the plate is positioned inside the scanner unit.

11. The method of claim 9, wherein counting a number of biological agents includes imaging the plate and counting biological agents based on an image of the plate.

12. The method of claim 9, wherein the biological growth plate is a thin film culture plate.
