I think I've seen slightly more practical ones before, but this one will do:

Umbrella lamp is a great idea but you don't see them very often.

I am having trouble recalling any device with a dual purpose that does either function particularly well:  Spork, Hair dryer/steam cleaner, lampshade/head gear :-)

They should put two motion-engines and an ink-jet printhead in the mouse, so that it prints on a sheet of paper like a air-brush.

It might be good for printing receipts for retail transactions, or somthing like the receipt our Motor Vehicle Administration prints out telling you what your number in line is. The PA will announce what station to go to when your number comes up. Our MVA, however, has a self-serve touch-screen and printer which prints out the receipt. I didn't look at it carefully enough to see if it was thermal or ribbon; I was just worried about getting through the line as quickly as possible.

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.
