International Classification:

G01N 2163

US Classification:

356318

Abstract:

A method and apparatus for determining an identity of at least one constituent on a soot that is deposited on a substrate is disclosed. The method includes the steps of sending a pulse of energy toward the substrate, focusing the energy to a predetermined point on the substrate to thereby generate a plasma on the substrate and to create at least one photon, detecting the photon using an analysis element, and identifying the constituent in the soot. The method may also include the step of determining the concentration of the constituent. Furthermore, the method may be used to determine the identity and concentration of at least one reactant in a flame of a burner or a reactant stream.

International Classification:

US Classification:

385 18, 385147

Abstract:

A micro-electro-mechanical system (MEMS) optical switch has a passive latching system. The switch includes a reflective element and a switch actuator for moving the reflective element to a first position based on a switching signal. The passive latching system is coupled to the switch actuator, where the passive latching system maintains the reflective element in the first position when the switching signal is discontinued. The latching system has a first magnet configuration coupled to a first portion of the switch actuator, and a second magnet configuration coupled to a second portion of the actuator. Thus, a magnetic force biases the magnetic configurations together when the reflective element is in the first position and the switching signal is discontinued. The latching is discontinued by using the switching signal to raise the temperature of one of the magnet configurations above its Curie point. The use of a passive latching system improves reliability, reduces cost, and enables the optical switch to serve as a viable alternative to conventional switching devices.

International Classification:

US Classification:

385 18, 385129

Abstract:

A micro-electro-mechanical system (MEMS) optical switch actuator and method for fabricating the actuator provide an anchor assembly that functions as a second electrode. The actuator has a reflective element assembly and a first electrode assembly for moving the reflective element assembly from a first position to a second position based on a switching signal. The actuator further includes an anchor assembly coupled to the reflective element assembly such that a spring force is generated in the reflective element assembly when the reflective element assembly is in the second position. The anchor assembly is electrically conductive such that the switching signal generates an electrostatic force between the anchor assembly and the first electrode assembly. The method for fabricating the actuator includes the step of coupling a multi-level reflection assembly to an optical circuit. The reflection assembly has an electrically conductive anchor assembly positioned at a first level with respect to the optical circuit and a mirror positioned at a second level with respect to the optical circuit.

International Classification:

US Classification:

359245, 359248, 359254, 359290

Abstract:

A moveable micromirror includes a supporting structure, a flexible post extending from the supporting structure, and a table extending radially from the end of the post along a plane generally perpendicular to the post, the table having a reflective surface facing away from the supporting structure. The post, preferably formed of single-crystal silicon, is dimensioned to be sufficiently flexible to allow the reflective surface to be selectively moveable and positionable, with at least two degrees of freedom, when urged by a suitable actuating force. A method of making an array of moveable micromirrors of this type includes deep etching a silicon substrate so as to form posts surrounded by trenches, etching back the surface of the substrate around the posts so as to allow the posts to protrude beyond the surface of the substrate, and affixing a table with a reflective surface thereon to the tops of a plurality of the posts.

Abstract:

A burner manifold apparatus ( ) for delivering reactants to a combustion site of a chemical vapor deposition process includes fluid inlets ( ), fluid outlets ( ), and a plurality of fluid passages ( ) extending therebetween. The fluid passages ( ) converge toward each other from the fluid inlets to the fluid outlets. One embodiment includes a manifold base ( ), a pressure plate ( ), and a manifold burner mount ( ) for mounting thereto a micromachined burner ( ). The fluid passages ( ) internal to the manifold base are configured to distribute symmetrically the fluid to the manifold burner mount. The fluid is then channeled through fluid passages in the manifold burner mount. The fluid passages converge, yet remain fluidly isolated from each other, and the fluid passages create a linear array for producing linear streams of fluid. Alternatively, the burner manifold apparatus may include a plurality of manifold elements in a stacked arrangement. In this alternative embodiment, the manifold elements are configured to produce a linear array of fluid passages at the top of the stack, increasing the number of fluid passages at each level of the stack closer to the top.

US Classification:

Abstract:

A fast light off flow-through ceramic substrate is provided that is particularly adapted for use as a catalytic converter. The substrate is formed from a body of ceramic material having axially opposing inlet and outlet ends for receiving and expelling the flow of automotive exhaust gas, respectively. The body contains a network of walls coated with a catalyst that define axially-oriented flow-through cell channels. The average thermal mass (ATM) of a first axial region of the walls adjacent to the inlet end is at least 20% less than the average thermal mass (ATM) of all of the walls. The lower average thermal mass of the walls in the first region advantageously shortens the light off time for the catalyst within the substrate to effectively neutralize automotive pollutants. The reduction of the average thermal mass in only the first axial region of the walls advantageously maintains the strength of the resulting body of ceramic material, and further increases the cool down time of the body.
