A microwave ink drying apparatus for an ink jet printer includes a microwave applicator. The applicator may be attached to a movable print carriage. The applicator may further comprise a slot antenna. The slot antenna may be formed as a dual slot, with one portion of the slot coupled to a wave launching cavity, and the other portion of the slot coupled to an impedance matching cavity.

An apparatus for carrying a target object having a plurality of surfaces, within a pulsed light sterilization chamber including a treatment zone within which pulsed sterilizing light is emitted, comprises: a transmissive carrier within the treatment zone detachably coupled to the target object, the transmissive carrier having a transmissivity of at least about 10% to light within the 250 to 350 nm wavelength range; and moving means coupled to the transmissive carrier for moving the target object on the transmissive carrier through the treatment zone, the plurality of surfaces of the target object being sterilized by the pulsed sterilizing light in the treatment zone. A system for sterilizing a target object having a plurality of sides, comprises: a pulsed light sterilization chamber comprising a treatment zone and means for emitting pulsed sterilizing light within the treatment zone; a moving means; and a transmissive carrier within the treatment zone detachably coupled to the target object, and coupled to the moving means which moves the target object on the transmissive carrier through the treatment zone, the plurality of sides of the target object being sterilized by the pulsed sterilizing light through the treatment zone.

A vacuum-sealable hatch that is vacuum sealed to a surface of a passthrough light sterilization device, and related methods of use, consists of a hatch body having at least a portion adapted to fit within an opening of the treatment chamber and a flexible piece attached to the hatch body. The flexible piece extends peripherally from the hatch body and includes a seating portion which is adapted to be vacuum sealed to a seating region of an interior surface of the treatment chamber. The hatch body and the flexible piece seal the treatment chamber from the outside environment, thereby preventing the free flow of microorganisms to and from the treatment chamber and the outside environment. In some variations, at least the seating portion of the flexible piece is transmissive to the light treatment such that surfaces underneath the seating region are treated by the light treatment.

An inductor for high current applications includes a nonconductive, tubular form which defines a tube axis and has a cylindrical outer surface. The outer surface is formed with a groove that extends helically about the tube axis. The inductor further includes a coiled, conductive wire that is formed with a plurality of turns. The wire is wound around the outer surface of the form with at least a portion of the wire disposed in the groove. With this structure, the form maintains a predetermined separation between adjacent turns of the coil preventing deformation of the coiled wire by strong magnetic forces that are generated when relatively high electrical currents are passed through the wire.

A system for charging a capacitor with relatively high energy pulses at a relatively high pulse repetition rate includes a voltage transformer. A resonant circuit is established having an inductor connected to the transformer's low voltage side and a capacitor connected to the transformer's high voltage side. A power supply cooperates with a switch assembly to generate a train of pulses, alternating in polarity, in the circuit. With this arrangement, the transformer core is reset after each pulse. A rectifying circuit operates on the alternating polarity pulses to create a train of constant polarity pulses for charging the capacitor. For the system, the maximum charging voltage is regulated by a control circuit having a probe for measuring the voltage across the charging capacitor. This measured voltage is used by the control circuit to selectively operate the switch assembly and regulate the maximum voltage across the capacitor.

A method of deactivating microorganisms in food products, packaging material, water, air, and other products involves illuminating the microorganisms using at least one short-duration, high-intensity pulse of broad- spectrum polychromatic light. In variations of this embodiment, the light has an intensity of at least 0.1 J/cm, the pulse duration is from between about 10 nanoseconds and 10 milliseconds, and/or at least 50% of the at least one pulse's energy is transmitted in light having wavelength from between about 170 and 2600 nanometers. Advantageously, the microorganisms may be oocysts, spores or poliovirus.
