Abstract
A method for preparing a deck for a process is disclosed. The deck can be prepared with any necessary components, and then an imaging device can capture an image of the deck. This image can be compared with a reference image and any differences identified. The differences can be indicated in the image and shown to an operator, such that the operator can correct any errors associated with the differences.
Claims21
A method of processing a sample using an automated liquid handler, the method comprising:
- a) receiving, using an input device of the liquid handler, a selection from a user of a protocol for processing the sample;
- b) displaying, on an output device of the liquid handler, a graphical depiction of an expected type of labware component to be loaded onto a deck of the liquid handler at a specified location according to the selected protocol;
- c) receiving, onto the deck of the liquid handler, a loaded labware component placed at the specified location by the user;
- d) imaging, using an imaging device, the deck of the liquid handler, to generate an image capturing the specified location;
- e) identifying in the image, by a processor of the liquid handler, the type of labware component loaded onto the deck at the specified location by the user;
- f) comparing the image to a reference image;
- g) displaying an indication, by the liquid handler, to the user, on a graphical user interface, if the identified type of labware component loaded onto the deck at the specified location is different than the expected type of labware component at the specified location based on the comparison of the image to the reference image according to the selected protocol;
- and
- h) processing, by the liquid handler, the sample according to the selected protocol.
6 more elements
An automated liquid handler for processing a sample, the automated liquid handler comprising:
- a) a computer apparatus configured to control the processes performed by the automated liquid handler, the computer apparatus including a processor, an input device coupled to the processor, and an output device coupled to the processor,
- wherein the processor is configured to receive, via the input device, a selection, from a user, of a protocol for processing the sample by the automated liquid handler,
- wherein the processor is further configured to display, on the output device, a virtual representation of an expected type of labware component to be loaded onto a deck of the liquid handler at a specified location according to the selected protocol;
- and
- b) an imaging device coupled to the processor, the imaging device configured to capture an image of a labware component loaded onto the deck, by a user, at the specified location, for processing the sample using the selected protocol,
- wherein the processor is further configured to identify, in the image, the type of labware component loaded onto the deck, by the user, at the specified location, and
- wherein the processor is further configured to display, on the output device, an indication that the deck may be incorrectly loaded if the identified type of labware component loaded onto the deck at the specified location is different than the expected type of labware component which is determined based on a comparison of the image to a reference image according to the selected protocol, wherein the output device is a graphical user interface.
4 more elements
A method of preparing a deck for a process, the method comprising:
- loading a protocol comprising at least one of:
- information about a processing step used to execute the process;
- and
- a component location layout on a deck in a state ready to execute the process according to the protocol;
- displaying a stored image of at least a portion of the deck in a state ready to execute the process according to the protocol;
- capturing an image of a placed component on the deck;
- identifying the placed component in the image;
- and
- indicating, using a graphical user interface, whether the placed component is at least one of a correct component and properly located on the deck based on a comparison of the image to a reference image in order to execute the process according to the protocol.
6 more elements
A method for initiating an instrument, the method comprising:
- receiving a protocol for executing a process;
- displaying a stored image of a deck with a component placed at a location, based on the protocol;
- capturing an image of the deck;
- and
- indicating, using a graphical user interface, a placed component on the deck based on a comparison of the image to a reference image.
