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.

摘要： One aspect is an aerosol detection arrangement including a light source for projecting a light beam. The arrangement includes a light collector configured to collect light scattered off liquid drops in an aerosol that enter the light beam and processing the scattered light into an output signal. The arrangement includes a controller for receiving the output signal from the light collector and uses the output signal to determine a predicted number of main liquid drops ejected.
