Methods and apparatus for determining the extent of etching in material by locating a detector element adjacent to a portion of the material that is to be etched. The width of the element varies. The resistance of the element is measured upon etching the portion.

Measurement of etching

A modulator is controlled in accordance with each sub-frame of a frame of image data. An aiming mechanism is physically adjusted to differently aim each sub-frame. Acoustical noise in physically adjusting the aiming mechanism is reduced.

An optical component of a projector is driven with a signal that contains one or more components that act to substantially cancel one or more unwanted oscillatory displacements of the optical component resulting from one or more unwanted oscillatory forces.

Methods and apparatus for controlling projectors

A fuel cell apparatus including fuel cell blocks electrically re-configurable in at least two arrangements by a control module.

A light direction assembly comprises a tip-tilt platform having a light direction member and at least one current coil coupled to the tip-tilt platform. The light direction assembly also includes a plurality of magnetic producing devices that are positioned in close proximity to the current coil. The magnetic producing devices are configured to selectively tilt the tip-tilt platform in response to a current flowing through the current coil. At least one shorted turn is also included in light direction assembly and is positioned in close proximity to the current coil.
