Abstract: The disclosure is directed to a sensor device including processing circuitry, at least one sensor coupled to the processing circuitry, a serial data interface coupled to the processing circuitry and memory responsive to the processing circuitry. The memory includes a static unique identification number. The serial data interface provides access to retrieve the static unique identification number and sensed data measured with the at least one sensor from the memory.

Abstract: A microdeposition apparatus and method according to the invention includes an interchangeable microdeposition head for depositing fluid manufacturing material on a substrate to form microstructures. The apparatus includes at least one of a plurality of microdeposition heads mounted on a head support and held above a substrate, which is mounted on a stage in controlled alignment with the microdeposition head. The control system coordinates the relative movement of the stage and microdeposition head while the fluid manufacturing material is discharged from the microdeposition head. A mounting bracket and computer system enable various microdeposition heads to be interchangeably used with the microdeposition apparatus.

Abstract: An expandable system such as a computer system includes a plurality of stacked functional modules with each module engaging an abutting module in a physically locked relationship. Electric power for the modular system is provided to all modules through power lines within each module housing for EMI shielding with abutting modules having mating electric power connectors.
