Invention performs an assay to determine presence or quantity of specific analyte in fluid sample. Representative device has two separate flow paths established sequentially in device with a single user activation step. First flow path delivers sample, and conjugate soluble binding reagents to solid phase. If analyte is present, an analyte:conjugate complex is formed and immobilized. Sample volume delivered by first path determined by absorbent capacity of solid phase, and not by amount of sample added to device. User need not measure sample volume. Sample/conjugate mixture is prevented from entering second flow path because capillary and surface energy of second flow path prevent it from being wetted by this mixture. Second flow path allows wash reagent to remove unbound conjugate and sample from solid phase to the absorbant, and optionally deliver detection reagents. Adaptable for many formats including, sandwich immunoassays, colloidal gold, sol particle, heterogeneous generic capture, and competitive assays.

A magnetic device is formed from a permanent magnet generating magnetic flux, an armature which can occupy two positions between four poles and an electromagnet winding to which current can be supplied to produce a magnetic flux in one direction or the other, the flux from the winding causing the armature to move into one position and continue to remain in that position after the current flow ceases. The device can be incorporated into a fluid valve to act as a drive for opening and closing the valve. It may also serve as the drive for opening and closing electrical contacts. Monostable operation can be achieved by locating a magnetic flux shunt at one end of the armature travel. A holding solenoid may be incorporated. A pivoting armature in a fluid tight chamber comprises a fluid flow controlling device. It can adopt either of two home positions in contact with two magnetic poles and is retained by magnetic flux from a permanent magnet. Fluid can flow into and out of the chamber via a first passage. A second passage extends through one of the poles to an opening in the pole face which is covered by the armature when the latter occupies one home position but is uncovered when the armature occupies its other home position. A third fluid passage extends through and leads to a second opening in another pole, which is covered when the armature occupies its said other home position. Passages in the poles house energy storing springs each of which is compressed as the armature approaches the pole. A push rod can extend through a passage in one of the poles for conveying armature movement externally of the device.

A system and process for thermolytic eradication of bacteria and biofilm in the root canal of a human tooth involve an elongated and flexible optical probe and a laser oscillator that provides the probe with low infrared energy. The optical probe is sufficiently long for insertion into substantially the entire length of the root canal of the tooth. The optical probe causes lateral dispersion of the radiation from the probe throughout the root canal. The radiation is provided at an energy density and for a period of time that are necessary to selectively target bacteria and live biofilm in the dentinal tubules of an entire root canal system, at once, thereby (1) inhibiting creation of a blackbody "hot tip", and (2) inducing laser interstitial thermotherapy (LITT) within the root-canal space.

An optical pulse source comprising a DPSS pump laser, a photonic crystal fiber (PCF), and acousto-optic modulator (AOM) gating device is disclosed. The pump pulses are coupled through lenses to the AOM gating device, which is synchronized to the pump laser and is operable to gate the pump pulses to a reduced repetition rate Rr=Rf/N, where Rf is the pump laser fundamental frequency. The pulses from the AOM are injected via optics into the PCF. Propagation through the PCF causes the pulses to broaden spectrally to produce optical supercontinuum pulses. An optical pulse source that further includes an acousto-optical tunable filter (AOTF) operable to convert the optical supercontinuum pulses into wavelength variable output pulses is also provided. A method of scaling the energy of the optical supercontinuum pulses is also disclosed.

A method for reducing the formation of deposits on the inner walls of a tubular heat exchanger through which a petroleum-based liquid is flowing comprises applying one of fluid pressure pulsations to the liquid flowing through the tubes of the exchanger and vibration to the heat exchanger to effect a reduction of the viscous boundary layer adjacent the inner walls of the tubular heat exchange surfaces. Reduction of the viscous boundary layer at the tube walls not only reduces the incidence of fouling with its consequential beneficial effect on equipment life but it also has the desirable effect of promoting heat transfer from the tube wall to the liquid in the tubes. Fouling and corrosion are further reduced by the use of a coating on the inner wall surfaces of the exchanger tubes.

Furthermore, the system is able to simulate anesthesia by generating block signals as a result of applying different anesthetic techniques by means of a dental syringe connected to the system.

The invention relates to methods of writing a light-guiding structure in a bulk glass substrate. The bulk glass substrate is preferably made from a soft silica-based material having an annealing point less than about 1380°K. A pulsed laser beam is focused within the substrate while the focus is translated relative to the substrate along a scan path at a scan speed effective to induce an increase in the refractive index of the material along the scan path. Substantially no laser-induced physical damage of the material is incurred along the scan path. Various optical devices can be made using this method.

A method of nanopatterning includes the steps of providing a resist film (12) and forming a pattern in the resist film (12). The resist film (12) includes a copolymer consisting of an organosilicone component and an organic component. An article (10) includes a substrate (14) and the resist film (12) disposed on the substrate (14). The copolymer of the organosilicone component and the organic component is sufficiently elastic, due to the presence of the organosilicone component, to be capable of resisting fracture and delamination during mold release. Furthermore, during pattern formation, the copolymer develops relatively low surface energy at an interface with the surface of a mold, as compared to conventional polymeric materials, and preferentially adheres to the substrate (14) rather than the mold, which provides for relatively easy mold release. The presence of the organosilicone component in the copolymer also allows the resist film (12) to exhibit excellent resistance to oxygen plasma etching.

The source/drain zones (140 and 142 or 160 and 162) of a p-channel IGFET (120 or 122) are provided with graded-junction characteristics to reduce junction capacitance, thereby increasing switching speed. Each source/drain zone contains a main portion (140M, 142M, 160M, or 162M) and a more lightly doped lower portion (140L, 142L, 160L, or 162L) underlying, and vertically continuous with, the main portion.

The dopant profile of a transistor may be obtained on the basis of an in situ doped strain-inducing semiconductor alloy wherein a graded dopant concentration may be established along the height direction. Consequently, the semiconductor alloy may be positioned in close proximity to the channel region, thereby enhancing the overall strain-inducing efficiency, while not unduly compromising the finally obtained dopant profile. Furthermore, additional implant species may be incorporated prior to selectively growing the semiconductor alloy, thereby avoiding implantation-induced relaxation of the internal strain.
