It's amazing how useful a micro-valve can be for the HVAC systems, but even if almost everyone has an air conditioning device installed in their homes, not many of them know how important a micro-valve is. Those interested in this topic can find more information from the Andy Lewis HVAC specialists about everything a HVAC system means.

Using a MEMS microvalve as a pilot for a traditional spool valve is analogous to using an accelerometer to trigger an airbag--the idea being that the MEMS element just senses conditions, then fires off a signal to the traditional "reaction" circuits to fire the airbag, in the case of accelerometers, or to turn up/down the flow in an HVAC in the case of a microvalve. The MEMS sensor just does a better job of sensing and responding, not actually performing the macro-sized action.

How about developing energy harvesting using the similar MEMS technology? By doing so, maybe we can really enjoy the nice fuel free system.

An interesting development - that a controller of a controller improves economy and saves space. Certainly there is a huge market for more cost effective and reliable HVAC and automotive systems. How is it "that switching to its micro-valves can increase the efficiency of existing HVAC systems by as much as 25 percent, making the technology good for retrofits"?

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
