ARRANGEMENTS OF CIRCUIT ELEMENTS AND FLUIDIC ELEMENTS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18032534 titled 'ARRANGEMENTS OF CIRCUIT ELEMENTS AND FLUIDIC ELEMENTS

Simplified Explanation

The patent application describes a fluidic die that dispenses fluid using fluidic elements.

  • The fluidic die includes fluidic actuators and fluid chambers to dispense the fluid.
  • An array of fluid feed holes is arranged in multiple dimensions to supply the fluid to the fluidic elements.
  • The fluidic die includes first circuit elements that operate at a lower power supply voltage and are placed between the fluidic elements.
  • Second circuit elements, which include active devices and operate at a higher power supply voltage, are placed outside the boundary of the space occupied by the fluidic elements and first circuit elements.


Original Abstract Submitted

In some examples, a fluidic die includes an arrangement of fluidic elements to dispense a fluid, each fluidic element of the fluidic elements including a fluidic actuator and a fluid chamber. An array of fluid feed holes is arranged in a plurality of dimensions to communicate the fluid with the fluidic elements, where each of multiple fluid feed holes along a first dimension of the plurality of dimensions is distinct from multiple fluid feed holes along a second dimension of the plurality of dimensions. The fluidic die includes first circuit elements operable at a first power supply voltage, the first circuit elements interspersed in regions between the fluidic elements along different axes of the fluidic die. The fluidic die includes second circuit elements operable at a second power supply voltage greater than the first power supply voltage, the second circuit elements comprising active devices and placed in a region outside of a boundary defining a space in which the fluidic elements and the first circuit elements are placed.
