Abstract: Response parameters for a population of RFID tags present in an inventory space are determined by (a) continuously scanning the inventory space to interrogate the population of RFID tags in the inventory space and receiving responses from multiple RFID tags within the population, (b) after multiple responses have been received from a specific RFID tag within the population, determining response times for the specific RFID tag corresponding to time periods between sequential ones of the multiple responses from the specific RFID tag, (c) calculating a maximum acceptable response time based at least in part on the response times determined in step (b), and (d) recording a response interval data set including one or more of the response times determined in step (b) and the maximum acceptable response time calculated in step (c).

Abstract: A decorator press for printing on metal cans has a pump unit, a distribution head, a sensing device and a processing circuit. The pump unit comprises a plurality of inlet ports, a first inlet port configured to receive an ink of a first color from a first ink source and a second inlet port configured to receive an ink of a second color darker than the first color. The distribution head is coupled to the pump unit and configured to spread fluid received from the pump unit across zones of a print roller. The sensing device is coupled to the press and configured to sense a characteristic of fluid flowing out of the distribution head. The processing circuit is configured to receive the sensed characteristic, compare the sensed characteristic to a predetermined threshold, and to provide an indication to a display based on the comparison.
