    Abstract: In one example, a drop detector includes a light source for illuminating drops passing through a drop zone, multiple light detectors near the light source for detecting light scattered off drops passing through the drop zone, and multiple lenses each configured to focus light from the drop zone on one of the light detectors. In one example, each light detector is arranged in the same plane with all of the other light detectors. In one example, the lenses are configured to focus light from two different spaces in the drop zone on different detectors or groups of detectors. In one example, the lenses are configured to focus light from a single space in the drop zone on multiple detectors.

    Abstract: An inkjet print head includes data signal lines configured to supply inkjet control voltages and non-volatile memory cell random access addresses. The inkjet print head includes an inkjet nozzle array wherein each nozzle in the array is configured to communicate with a data signal line. Also a non-volatile attribute memory cell array is included in the inkjet print head wherein each memory cell in the array is accessed through a data signal line shared with the nozzle array.

    Abstract: An integrated circuit (IC) erasable programmable read-only memory (EPROM) structure for a thermal inkjet printhead includes: a fire line to provide fire line data; a select line to provide selecting data; a firing cell coupled to the fire line; an EPROM cell coupled to the fire line; a selector cell coupled to the select line, the firing cell and the EPROM cell; and a data switching circuit to provide address data to the firing cell or the EPROM cell. The data switching circuit and the selector cell selectively enable transfer of the fire line data from the fire line to the firing cell or the EPROM cell as a function of state of the selecting data on the select line and the address data from the data switching circuit.
