Sub stream auto sampling

A system, comprising:

• an inspection unit, comprising:
• a camera configured to capture an image of a sample;
• light configured to illuminate a sample;
• a processor configured to process the captured image;
• a memory configured to store the captured image;
• and
• a sorter unit that is configured to divert a sub stream of samples, from a main stream of samples, toward the inspection unit, wherein the inspection unit further comprises an output chute that directs the sub stream of samples toward the main stream of samples.

• an inspection unit, comprising:
• a camera configured to capture an image of a sample;
• light configured to illuminate a sample;
• a processor configured to process the captured image, and
• a memory configured to store the captured image;
• a sorter unit that is configured to divert a sub stream of samples, from a main stream of samples, toward the inspection unit, wherein the sorter unit comprises:
• a vacuum system comprising:
• a device that is capable generating a vacuum;
• a pressurized air inlet;
• and
• a valve, wherein the pressurized air inlet is connected to the valve, and wherein the valve controls a flow of pressurized air through the device.

A method, comprising:

• (a) diverting a sample from a main stream of samples toward an inspection unit using a vacuum system comprising:
• a device that is capable generating a vacuum;
• a pressurized air inlet;
• and
• a valve, wherein the pressurized air inlet is connected to the valve, and wherein the valve controls a flow of pressurized air through the device;
• (b) inspecting the sample by the inspection unit, wherein the inspecting includes illuminating the sample, capturing an image of the sample, and storing the captured image;
• and
• (c) after the inspecting of (b), directing the sample back to the main stream of samples.
