A multi-color cavity ringdown based spectrometer system is housed in a light tight enclosure to detect the presence of trace quantities of gas phase molecules emanating from a subject, explosives, drugs, or hazardous materials. A method is also disclosed for simultaneous real time detection of gas phase molecules emanating from explosives, drugs, hazardous materials, a subject's breath skin or bodily fluid.

Multi-color cavity ringdown based detection method and apparatus

A body limb movement limiter restrains the movement of a person's arm so as to protect the person's shoulder or restrains the movement of a person's lower leg with respect to the upper leg so as to protect the person's knee. The device uses a housing having a reel disposed therein with a tether attached thereto and a shear thickening non-Newtonian fluid disposed within the housing so that the fluid acts on the reel during a payout procedure of the tether. The housing is attached to a strap secured about the torso of the person while the free end of the tether is secured about the person's arm. Alternately, a pair of arms are pivotally secured to each other within a housing having the non-Newtonian fluid therein for limiting movement of one arm with respect to the other.

A multi-color cavity ringdown based spectrometer is housed in a light tight enclosure to detect the presence of trace quantities of gas phase molecules emanating from explosives, drugs, or hazardous materials being transported through the enclosure or compounds contained in a patient's breath. A method is also disclosed for detecting gas phase molecules emanating from explosives, drugs, hazardous materials, or a patient's breath.

A method and apparatus for removing minute particles from a surface of a sample are provided that prevent redeposition of the particles onto the surface. By combining thermophoresis with laser assisted particle removal (LAPR), the methods and apparatus remove minute particles (for example, micrometer and nanometer sizes) and assure that they will not redeposit.

A detection coil for use in nuclear resonance magnetic (NMR) spectroscopy and a method of manufacture thereof. At least two film layers of material are deposited on an outer surface of a cylindrical tube of dielectric material. The layers are patterned to form a solenoid on the tube. At least one of the deposited materials is a conductor.

Laser-assisted fabrication of NMR resonators

A method for producing feedthroughs in a substrate having a front and back surface, wherein the substrate either has a hole or absorbs radiation at a given wavelength. The method includes selecting and intimately bonding a sheet to the back surface of the substrate with an adhesive which is absorptive at the given wavelength. If the substrate has a hole, an exposed area of the sheet is illuminated with laser radiation at the given wavelength and at a power level sufficient to ablate a portion of the sheet behind the exposed area, thereby creating the feedthrough in the substrate. If the substrate has no hole, an area on the front surface of the substrate is illuminated with laser radiation at the given wavelength and at a power level sufficient to ablate a portion of the substrate and a portion of the sheet behind the area, thereby creating the feedthrough in the substrate. The sheet can then be removed from the substrate. Alternatively, if the sheet is conductive, the sheet can remain bonded to the substrate and can serve as a ground plane for the substrate. If the sheet is an insulator, the feedthrough is an insulated feedthrough and if the sheet is conductive, the feedthrough is a conductive feedthrough. This procedure can be extended to produce a two conductor feedthrough.

Combined infant car-seat and stroller

Method and apparatus for removing minute particles (as small as submicron) from a surface to which they are adhered. An energy transfer medium is interposed between each particle to be removed and the surface to which the particles are adhered. The medium is an irradiated with laser energy at a wavelength which is strongly absorbed by the medium. The medium absorbs sufficient energy to cause explosive evaporation with sufficient force to dislodge the particles. Preferably means are provided to remove dislodged particles to prevent redeposit on the surface.
