LED display voltmeters

Half-inch-high bright red LEDs are used on the display panel of the DMS-30PC-RL series of digital-panel voltmeters. The display draws 50 mW of power, and the meter gives 3.5-digit resolution. Models are available in either 𫐰-mV, ۬-, or 䔸-V models. The 12-pin DI¥packages measure 2.2 ¥ 0.92 ¥ 0.5 in.

A diagram shows NIST’s ion trap used for reversible “quantum squeezing” to amplify and measure ion motion. The ion (white ball) is confined 30 microns above the trap surface by voltages applied to the eight gold electrodes and the two red electrodes. Squeezing--that reduces the uncertainty of motion measurements--is achieved by applying a specific signal to the red electrodes. The ion is moved by applying another type of signal to one of the gold electrodes. Then the squeezing is reversed, and the blue electrodes generate magnetic fields used to decode the amplified motion measurements.
