The measurement arm includes: measurement arm joints, each of which has a measurement arm joint axis, which extends coaxially to the joint axis of an associated joint of the articulated arm; rotary encoders, each encoder being associated with one of the measurement arm joints; and measurement arm link elements, which connect the measurement arm joints in a serial measurement arm arrangement.

A two-phase liquid immersion cooling system is described in which heat generating computer components cause a dielectric fluid in its liquid phase to vaporize. The dielectric vapor is then condensed back into a liquid phase and used to cool the computer components. Using a pressure controlled vessel and pressure controller, the disclosed system may be operated at less than ambient pressure. By controlling the pressure at which the system operates, the user may influence the temperature at which the dielectric fluid vaporizes and thereby achieve increased performance from a given computer component. Utilizing robotic arms and slot-in computing components, a self-healing computing system may be created.

A system and method are provided for fabricating 3D structures from biomaterial. The system includes a printer assembly having a dual-arm assembly including an upper arm, and a lower arm connected by an elbow joint to the upper arm. A disposable barrier encloses a printing surface from an external environment and from components of the printer assembly. The upper arm and lower arm are inserted into an inlet of the barrier, so as to be isolated from the print surface. The lower arm is provided with an extruding system, and the extruding system includes an actuator-driven syringe configured to deposit biomaterial on the print surface. The biomaterial is deposited on the print surface to carry out 3D fabrication in an aseptic environment.
