摘要： 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.

摘要： A fluid ejection assembly includes a fluid slot formed in a first substrate and a channel formed in a chamber layer disposed on top of a second substrate. The bottom surface of the second substrate is adhered to the top surface of the first substrate and fluid feed holes are formed between the fluid slot and the channel. A fluid ejection element is at a first end of the channel and a pump element is at a second end of the channel to circulate fluid horizontally through the channel and vertically through the fluid feed holes.

摘要： One aspect is a light source assembly in a drop detection arrangement. The light source assembly includes a light source and a gradient-index lens array to at least partially collimate light from the light source and to project a collimated light beam into the drop detection arrangement in a direction transverse to a drop direction of droplets in the drop detection arrangement. The light source assembly produces the light beam such that it has a beam width in a direction transverse to the drop direction that is larger than a beam height in the drop direction.
