Disclosed are methods and devices suitable for producing an electron beam.

Methods and devices for producing an electron beam

Disclosed are passive millimeter wave detection devices that in some embodiments are useful for detecting objects such as weapons obscured underneath clothing. Also disclosed are methods for detecting objects using millimeter waves, in some embodiments, objects such as weapons, obscured underneath clothing.

Passive millimeter-wave detector

Disclosed are methods and devices suitable for generating electron beams and pulses of radiation. Specifically, in some disclosed embodiments, multiple emitting electrodes of a ferroelectric emitter are sequentially activated, generating a relatively long electron beam pulse that is substantially a series of substantially consecutive short electron beam pulses generated by the sequentially-activated individual emitting electrodes.

Ferroelectric emitter for electron beam emission and radiation generation

An ink jet print head comprises a print head matrix having nozzles for drop&#x2225; formation and release opening onto a print side surface of said matrix and individual local micro-reservoirs, each associated with the local nozzles. The reservoirs open onto an ink supply surface of the matrix and are supplied with ink by capillary action from wiping or spraying of ink regularly refreshed onto the ink supply surface. The design allows for a print head that substantially covers the area of the print media and thus permits stationary printing. Printing is rapid and the ink supply arrangement allows for reliable ink supply at atmospheric pressure.
