  Cornell News: reciprocating cantilever atomic battery
The cantilever is pulled down toward the positively charged film until it is near enough for a current to flow and equalize the charge.
Lal also has built versions of the device in which the cantilever is made of a piezoelectric material that generates electricity when deformed, releasing a pulse of current as the rod snaps up.
But the sensors might be developed to detect the presence or absence of particular gases, since introducing a gas to the device changes the flow of current between the rod and the base, in turn changing the period or amplitude of the oscillation.

 Cantilever plate connecting assembly - Patent 4959940
A cantilever plate connecting assembly according to claim 1, further including at least one transverse force bar (10) of corrison-resistant material that provides for the absorption of transverse forces and the transverse force bar being held by the face plates (6).
The present invention relates to a cantilever plate connecting assembly for the insulated, close-linkage joining of a floor-ceiling plate to a cantilever plate, with a slab-form insulation body, and reinforcing bars extending therethrough.
This problem is solved by a cantilever plate connecting assembly that is distinguished in that at least two reinforcing bars, in vertical arrangement one over the other, are held on both sides of the insulation body in face plates of corrosion-resistant material.

 Cantilever Geometry
With most cantilevers, the mechanic has considerable latitude in setting up this cable system, and it makes a real difference in the performance of the brakes what he or she does, especially with the newer "low-profile" cantilevers.
Traditional cantilever brakes, however, allow the mechanic to adjust the mechanical advantage to a considerable extent, mainly by adjusting the length of the transverse cable and the height of the cable yoke.
The small cantilever angle of narrow-profile brakes causes the anchor arm (PA) to be nearly vertical, especially on mountain bikes that have wide-set pivot bosses and narrow rims.

Cantilever is a clumsy word, reflecting a basic problem for designers - how to achieve a satisfactory appearance from a bridge which includes two types of structure, cantilever and suspended span.
But of course this is not an efficient way of making a cantilever, and it does not allow of building without a lot of falsework, which is one advantage of a proper cantilever.
The problem with appearance is that the cantilevers need to taper from the supports to the ends, whereas the suspended span ideally needs to be narrow at the ends and thicker in the middle.
