摘要： A fluid ejection controller interface includes input logic to receive control data packets and a first clock signal, each control data packet including a set of primitive data bits and a set of random bits, wherein the input logic identifies the random bits in the received control data packets to facilitate the creation of modified control data packets. The fluid ejection controller interface includes a clock signal generator to generate a second clock signal that is different than the first clock signal, and output logic to receive the modified control data packets, and output the modified control data packets to a fluid ejection controller of a fluid ejection device based on the second clock signal.

摘要： A print component includes an array of fluidic actuation structures including a first column of fluidic actuating structures addressable by a set of actuation addresses, each fluidic actuating structure having a different one of the actuation addresses and having a fluidic architecture type, and a second column of fluidic actuating structures addressable by the set of actuation addresses. Each fluidic actuating structure of the second column has a different one of the actuation addresses and has a same fluidic architecture type as the fluidic actuating structure of the first column having the same address. An address bus communicates the set of addresses to the array of fluidic actuating structures, and a fire signal line communicates a plurality of fire pulse signal types to the array of fluidic actuating structures, the fire pulse signal type depending on the actuation address on the address bus.

摘要： An integrated circuit to drive a plurality of fluid actuation devices includes a strain gauge sensor, an amplifier, and a voltage bias generator. The strain gauge sensor generates a strain gauge signal. The amplifier amplifies the strain gauge signal. The voltage bias generator offsets the amplified strain gauge signal.

摘要： A communicating print component a print head comprising a number of memory bits and a single lane analog bus conductively coupling the number of memory bits to a pad located on the exterior of the print head. The pad is to transmit an electrical signal from the number of memory bits, wherein the electrical signal indicates a combination of all selected bits of the number of memory bits.

摘要： An integrated circuit includes thermal tracking logic, control logic, and an output interface. The thermal tracking logic determines a temperature of a fluid ejection die. The control logic defines an emulated parameter of the fluid ejection die as a function of the temperature of the fluid ejection die. The output interface outputs the emulated parameter to a printer system based on the function and the temperature of the fluid ejection die.
