Abstract: A system for treating a fluid comprising a treatment chamber; a light source for emitting light, such that at least a portion of the light travels within the treatment chamber; and a treatment area within the treatment chamber; wherein a flow profile of the fluid in the treatment area matches the fluence profile of the light that travels within the treatment area. An apparatus for providing a substantially uniform light treatment of a flowing fluid by providing a light source or sources and establishing (or controlling) the flow such that the combination of light intensity and flow velocity provides substantially uniform treatment (i.e. the faster moving fluid streams are treated at higher intensity and the slower moving fluid streams are treated at lower intensity).

Abstract: 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.

Abstract: Methods and apparatus for precisely monitoring and collecting data relating to the light treatment of a product in a treatment system. In one implementation, a method for use with a treatment system using light comprises the steps of: illuminating a product with a light treatment comprising light having a spectrum of wavelengths within a range of 170 to 2600 nm, the light treatment for treating the product; and measuring a fluence of a portion of the light treatment for each of a plurality of wavelengths of the spectrum of wavelengths simultaneously. In preferred implementations, the light treatment is a pulsed light treatment and the product is a biological fluid product flowed through a treatment chamber. Furthermore, in preferred implementations, the light treatment is for the deactivation of microorganisms, such as viruses, bacteria, fungus, and other pathogenic and non-pathogenic microorganisms.

Abstract: An ink jet printer having an inking system that includes an ink jet cartridge, a large ink reservoir mounted inside the housing of the ink jet printer at a location which is remote from the ink jet cartridge and tubing connecting the ink reservoir to the ink jet cartridge. The large ink reservoirs may be pancake shaped, and may be stacked in side by side horizontal manner within the housing. A portion of the reservoir is transparent, and is visible to the operator for operator monitoring of ink level through openings in the printer housing placed in juxtaposition with the transparent portion of the large ink reservoirs.

Abstract: A fluid treatment system consists of a light source for providing light and a flexible treatment chamber having an input port and an output port, at least a portion of the flexible treatment chamber positioned to receive the light. The at least the portion of the flexible treatment chamber is transmissive to at least 1% of the light having at least one wavelength within a range of 170 to 2600 nm and the flexible treatment chamber is adapted to allow a fluid to be treated to be flowed via the input port therethrough at a specified rate and out the output port. The light source illuminates the fluid as it flows through the flexible treatment chamber in order to deactivate pathogens within the fluid. In some embodiments, the light source is a pulsed light source for emitting short duration, pulses of polychromatic light.

Abstract: A fluid treatment system, and methods of use, the system includes a sealed fluid flow path including a treatment chamber portion and containing a fluid to be passed therethrough and treated with light. The treatment zone is transmissive to at least 1% of the light having at least one wavelength within a range of 170 to 2600 nm. In some variations, the sealed fluid flow path is removable from a light treatment system. In some variations, the flow path includes a first fluid container portion for containing the fluid to be treated and coupled to the treatment chamber portion and a second fluid container portion coupled to an output of the treatment chamber portion. The fluid flow path is designed to be disposable and easily replaceable.

Abstract: Methods and apparatus for precisely controlling a light treatment of a treatment system for treating a product. In one implementation, a method for use with a fluid treatment system using light comprises the steps of: estimating a particular velocity of moving particles within a fluid flowing through a treatment chamber of the fluid treatment system using pulses of light as a light treatment, the fluid flowing at a mass flow velocity, the treatment chamber and the fluid being transmissive to at least 1% of light having at least one wavelength within a range of 170 to 2600 nm; and setting a flash rate of the pulses of light based on the particular velocity in order to optimize the light treatment. Furthermore, in preferred implementations, the light treatment is for the deactivation of microorganisms, including viruses, bacteria, fungus and other pathogenic and non-pathogenic microorganisms.

Abstract: An ink jet printer having an inking system that includes an ink jet cartridge, a large ink reservoir mounted on the ink jet printer at a location which is remote from the ink jet cartridge and tubing connecting the ink reservoir to the ink jet cartridge. The tubing and the ink reservoir are permanently mounted within the ink jet printer. Only the ink jet cartridge needs to be replaced, because the jet plate has a finite life span during which the print quality from the jet plate is satisfactory. The ink jet cartridge includes a quick release fitting which enables the easy disconnection of an old ink jet cartridge and reconnection of a new ink jet cartridge with the tubing. Further, the size of the ink jet cartridge is reduced since almost all of the ink storage is moved to a location which is remote from the ink jet cartridge.

Abstract: A reflow solder head has its heater bar (30) mounted so as to cause the heater bar to contact a tilted reflow surface (50) and align itself with the tilted surface without tip skid. The heater bar is mounted to its movable drive ram (40) by two independent pivots (36,42), both nominally positioned on a line normal to and in the center of the heater bar itself. The first pivot (36) closer to the heater bar allows the heater bar to rotate about its first point of contact (54) with the tilted reflow surface. The second pivot (42) allows lateral movement of the first pivot (36) without tip skid during the rotation of the heater bar about its first point of contact. This double pivot mechanism eliminates the tendency of the heater bar to skid along the reflow surface.

Abstract: A parallel-gap welder applies a precisely controlled force to the weld head (40) by means of a solenoid (60) having a plunger (72) aligned with the axis of the welding electrodes (50,52). To precisely control the amount of force applied by the solenoid a load cell (80) is interposed between the weld head (40) and the solenoid plunger (72) to provide a feedback force signal (158) indicative of the force applied by the solenoid. The feedback force signal is used to control current through the solenoid coil (68) and thereby servo the applied force to a force command input. The solenoid plunger (72) and load cell (80) are axially aligned with the axis of the electrodes (50,52) and solenoid force is applied through a universal joint (76,78) connection to assure an in-line driving force on the electrodes.

Abstract: Two parallel elongated closely spaced electrodes for welding electronic circuit components are mounted for limited rotation about an axis extending generally longitudinally of the electrodes to allow the electrode pair to be oriented with respect to a workpiece without angularly moving the workpiece. The electrodes are mounted in a pair of mutually aligned and mutually insulated bobbins against which are firmly pressed a pair of contacts for conducting weld current between the electrodes. The bobbins and the electrodes mounted therein are free to rotate relative to the fixed contacts, but the latter are firmly pressed against the bobbins to provide increased contact pressure and decreased electrical resistance between the contacts and bobbins and to provide a relatively large surface area for such contact.
