Identify and describe a commercial vision system capable of reading a Unique Device Identifier (UDI) code printed on the end of cans containing food products such as green beans. The cans travel down a conveyor at speeds of 600 cans/minutes. The vision system must identify any and all rogue cans, and send an appropriate signal to a device which will eject the can from the conveyor stream.

Hospital personnel routinely examine patient records for error, such as incomplete insurance information, on incomplete patient history, or missing/incomplete medical records. On average, about 270 new patients are admitted each day. Historically, about 8% of these records have contained errors. If a random sample of 40 new patient records is checked each day, what is the probability that this sample will contain at least two patient record with missing information?

A car accident expert is assigned to a case where the insurance company suspects the car company to use lower quality steel (lower TS) than the standards in their bumpers. The expert is given a post-crash bumper to run his test on. Since the bumper is completely deformed, he cannot place it into the normal bumper tensile tester. He is thinking about running a hardness test on the deformed bumper to estimate the TS of the steel to test the insurance company's theory. Do you think his method is acceptable? why?
