The present invention relates to a method of fabricating a transparent gas barrier film by using plasma surface treatment and a transparent gas barrier film fabricated according to such method which has an organic/inorganic gradient interface structure at the interface between an organic/inorganic hybrid layer and an inorganic layer. Since the method of the present invention is capable of fabricating a gas barrier film by plasma surface treatment instead of deposition under high vacuum, it can mass-produce a transparent gas barrier film with excellent gas barrier properties in an economical and simple manner. Further, since the transparent gas barrier film fabricated according to the method of the present invention shows excellent gas barrier properties and is free of crack formation and layer-peeling phenomenon, it can be effectively used in the manufacture of a variety of display panels.

A birefringent interferometer system is described which uses nematic liquid crystal cells to produce variable optical path differences (OPD) between light of different polarization states that are interfered at a polarizing analyzer. Fixed retarders may also be incorporated to extend the range of OPD. The interferometer provides wide field-of-view, continuously variable path difference over a large range, and an on-board monitor of OPD for ensuring accurate settings of path difference, and hence, an accurate wavelength scale in the spectra produced by the apparatus. The system can further incorporate additional polarizing optics so it responds equally well to light of any incident polarization state without loss of efficiency.

A device for the aiming and the visual indication of a reading area of a coded information reader includes an emitter which emits a preferably collimated light beam towards a reading area of a coded information reader, as well as a refractive optical element. The refractive optical element deflects at least one first portion of the light beam so as to generate at least two different beam portions active on at least two different zones of the reading area along at least two different optical paths. The refractive optical element includes opposed first and second faces which respectively collect the light beam and project the at least two beam portions onto the reading area. The second face includes at least one (preferably more than one) first surface portion inclined by a predetermined angle α with respect to the first face and adapted to deflect the at least one first light beam portion by a predetermined deflection angle β with respect to the optical axis Z. The device is adapted to be mounted on a coded information reader to provide the operator with a visual indication of the reading area framed by the reader, before carrying out the reading of the information contained in the area.

Method and apparatus for monitoring and reporting hand washing at a sanitizing station employs a sensor for signaling the dispensation of a sanitizing agent from a dispenser and setting a clear signal to permit passage through a portal, such as an entrance to a room. The module in turn includes an input element, an output element, a processor, and memory. The module operates in person and administrator modes. In the person mode, the module responds to an input signaling that a person has dispensed sufficient sanitizer to mitigate the spread of germs from care giver/health care worker to patient. The person activates the sanitizer to dispense the sanitizer liquid or foam and that action signals that the cleaning agent has been dispensed and turns on the entrance permitted light. If the dispenser is not activated or the amount of sanitizer dispensed is not adequate to sanitize the person's hands, a sensor positioned at the entrance of the door alarms. The apparatus may be installed quickly and easily, at lower cost, in a wide variety of sanitization stations, and can be used with existing, preinstalled sanitization dispensers or with a new dispenser. When in administrator mode, the module allows for passage of beds, equipment and supplies to the room.

In a method for monitoring the condition of a mechanical seal in an apparatus provided with a rotating part, in particular in a pump which has a rotating shaft for the forwarding of a fluid, the sound emission of the seal is continually measured at discrete times in the operating state of the apparatus and at least one statistical characteristic value is won from the acoustic signals. The analog acoustic signals are converted prior to the determination of the statistical characteristic value into analog demodulated signals, the maximum frequency of which is less than about 50 kHz.

An aircraft capable of thrust-borne flight can be automatically retrieved, serviced, and launched using equipment suitable for a small vessel. For retrieval, the aircraft hovers over a base apparatus having one or more rails which bound a space into which the aircraft can safely descend. When the aircraft's measured position and velocity are appropriate, the aircraft descends promptly such that a spanwise component on the aircraft engages the rails. The teeth restrain the aircraft in position and orientation, while the rails bring the aircraft to rest. Articulation of the rails is used to park the aircraft in a servicing station. Connections for refueling, recharging, and/or functional checks are made in preparation for launch. Launch is effected by removing connections and restraints and articulating the rails to put the aircraft in an appropriate position and orientation. The aircraft uses its own thrust to climb out of the apparatus into free flight.

A process for imparting hydrophilic properties to a polymeric membrane by exposing the membrane to an acrylate monomer containing hydrophilic segments, such as ethylene oxide, and a hydrophilic functional group, a diacrylate monomer containing hydrophilic functional groups, and an initiator for facilitating crosslinking and polymerization reactions.

In accordance with one specific embodiment of the present invention, the ion assisted deposition source for thin films comprises an axially symmetric discharge region into which an ionizable gas is introduced, a sputter target at one end of that region, an axially symmetric magnetic field within and extending out the opposite and open end of that region, an anode around the circumference of that region, and an electron emitting cathode located near the open end of that region. Particles are sputtered from the sputter target, pass through the discharge region, and are deposited on a deposition substrate located exterior of both the discharge region and the deposition source. A beam of energetic ions from the discharge region bombards the film being deposited to improve the adhesion, density, and other properties of that film. The density of the plasma can be controlled with the emission from the cathode, the emission of sputtered particles from the sputter target can be controlled with the negative potential of that target, while the energy of the ions used to assist in the deposition can be controlled with the positive potential of the anode. The deposition source thus simultaneously generates a flux of sputtered material with which to deposit a film on a substrate and a beam of energetic ions to assist in that deposition, and does so with a simple and economical apparatus.
