Cady held more than 50 patents, and was the inventor of the crystal-controlled oscillator, the highly selective narrow-band crystal filter, one of the principal theorists of the ferroelectricity in crystals, and a historian of the science of piezoelectric crystals.

It was the work of the aforementioned Espenschied and Herman Affel of Bell Labs who patented their piezoelectric crystal " lattice " filters to provide sharp bandpass cutoff that made all single-sideband carrier work developed at Bell Labs possible.

The acceleration causes the three disks in the safety mechanism to rotate 90?in succession, ungrounding the circuit; the circuit from the nose to the base of the detonator is then completed when the piezoelectric crystal is crushed on impact.

Michelson interferometers have the largest field of view for a specified wavelength, and are relatively simple in operation, since tuning is via mechanical rotation of waveplates rather than via high voltage control of piezoelectric crystals or lithium niobate optical modulators as used in a Fabry P�rot system.

The company developed the Micro Piezo inkjet technology, which used a piezoelectric crystal in each nozzle and did not heat the ink at the print head while spraying the ink onto the page, and released Epson MJ-500 inkjet printer ( Epson Stylus 800 cartridge ) in March 1993.

An improvement over the 8080 is that the 8085 can itself drive a piezoelectric crystal directly connected to it, and a built-in clock generator generates the internal high amplitude two-phase clock signals at half the crystal frequency ( a 6.14 MHz crystal would yield a 3.07 MHz clock, for instance ).

Although that is no problem for the makers of airbag systems _ who are by far the biggest purchasers _ and far cheaper than a piezoelectric crystal device, Lemaire said that the cost is still about twice what home appliance makers are willing to pay to create washing machines that can sense when their loads are off balance and use the information to automatically adjust their spin cycles.
