    IPC: B41J2/045

    Abstract: A print component includes a plurality of data pads, a clock pad to receive an intermittent clock signal, and a plurality of actuator groups each corresponding to a different liquid type and to a different one of the data pads. Each actuator group includes a plurality of configuration functions, an array of fluid actuators, and an array of memory elements including a first portion corresponding to the plurality of configuration functions and a second portion corresponding to the array of fluid actuators. Each time the intermittent clock signal is present on the clock pad, the array of memory elements to serially load a segment of data bits from the corresponding data pad, including loading a first portion of data bits into the first portion of memory elements, and loading a second portion of data bits into the second portion of memory elements.

    IPC: B01L3/00

    Abstract: An apparatus includes a polymer base layer having a surface. A die has a surface that is substantially coplanar with the surface of the polymer base layer. The die includes a fluidic actuator to control fluid flow across the surface of the die. A fluidic channel is coupled to the polymer base layer to provide a fluidic interconnect between the die and a fluidic input/output port.
