For use in cathodoluminescent field emission display devices, a cathode emitter can comprise an inverted field effect transistor having a diamond film or other low effective work function material deposited onto the channel layer of the transistor, such that the diamond film provides a source of primary electron emissions. A variable voltage source is applied to the gate of the transistor creating an electric field that controls the conductivity of the channel layer, thereby activating or deactivating electron emissions from this cathode emitter structure. In addition, electron blocking junctions can be incorporated into the emitter structure to inhibit current flow through the device during a deactivated state. In a variation, the transistor of the cathode emitter has the diamond film being deposited onto an electrically conductive pad that is electrically connected to, and extending outwardly from, the transistor. Alternatively, a sideways laterally gated transistor structure can be used with the emitter surface being applied to the transistor's drain.

For use in cathodoluminescent field emission display devices, a gated channel layer of an inverted field effect transistor functions as the electron emissive layer for a flat film surface conduction cathode emitter. In such emitters, electrons are emitted from the surface of a flat thin emissive film when an electric current is caused to flow through the film in parallel with the surface of the film. An electric field caused by a variable voltage source being applied to the gate of the transistor can control the conductivity of the channel layer, thereby controlling the level of electron emissions from the cathode emitter structure. In a variation, the field effect transistor is constructed with a two-tier structure that during operation is designed to keep conduction near the surface of the transistor. As a result, this device pushes electrons towards the exposed surface where they can then escape from the channel layer to bombard the cathodoluminescent phosphor anode. To ensure against unwanted anode currents, electron blocking junction elements can be incorporated on either side or both sides of the channel and positioned over a widened gate electrode, such that they are commonly gated along with the channel to respond to a single control voltage input to the gate electrode.

This is a spread spectrum radio frequency (RF) communication system whose rpose is to "spread" the information bandwidth such that when it is de-spread any atmospheric interference (including jamming is spread rather than de-spread. A "low probability of exploitation" is obtained through the use of multiple modulations each of which creates a distinct spread spectrum symbol at the transmitter, and the reception of which requires a "match" condition at the receiver to determine the data bit state. The symbol sequence is known by the appropriate receivers and the collection of data bits forms a message.

An unscrambler for unscrambling a bundle of elongated tubes comprises a plurality of forward belt-support columns, a plurality of aft support columns, a plurality of flexible belts suspended in parallel between the forward and aft support columns forming a belt magazine for retaining the bundle of tubing which extend longitudinally in a direction perpendicular to the belts, and a plurality of ramps positioned longitudinally between each pair of adjacent belts sloping upwardly towards the forward support columns and positioned such that they provide support for the bundle in the belt magazine. The ramps each have a wedge extending from their upper surfaces, and each wedge has a forward face which intersects the upper surface of the ramp to form a v-shaped groove on the ramp. Furthermore, each of the belts have a cleat attached to their upper surfaces. Tightening of the belts causes the bundle to be guided up the ramps and lifted above the wedges on the ramps such that the bundle expands outwardly.
