Filed:

Feb 22, 2000

Appl. No.:

09/510367

Inventors:

Andrew A. Berlin - San Jose CA
Elmer S. Hung - Foster City CA
Feng Zhao - Campbell CA

Assignee:

Xerox Corporation - Stamford CT

International Classification:

G01M 700

US Classification:

73662

Abstract:

A micromechanical resonator including a motion arresting mechanism to rapidly damp the vibration of a resonator beginning at any given moment in time to remove vibration caused by previous events. An electrostatic clamp uses a bias voltage between an electrode and the resonator to damp the resonator and return it to its equilibrium position. A mechanical clamp includes an actuator that forces the mechanical clamp to contact the resonator. These micromechanical resonators facilitate condition based monitoring of complex electromechanical machines and components by allowing signature analysis in multiple temporal and frequency domains.

International Classification:

G01H 1108

US Classification:

7659, 73660

Abstract:

A MEMS-based system that enables low cost, low power, single chip realization of real-time signal detection and fault diagnosis. The system is suitable for analyzing the time-varying properties of a signal that are important for condition-based monitoring of electro-mechanical machines or structures. The system includes mechanical sensors that sense input signals such as vibration, signal templates of fault conditions, logic units that detect, store, and compare signal features to provide a diagnostic state, and an output readout mechanism to couple the diagnostic state to readout device that provides an external signal.

International Classification:

B41J 205

US Classification:

347 21

Abstract:

A method of marking is disclosed in which a propellant stream is passed through a channel and directed toward a substrate. Liquid marking material, such as ink, is controllably introduced into the propellant stream and imparted with sufficient kinetic energy thereby to be made incident upon a substrate. A multiplicity of channels for directing the propellant and marking material allow for high throughput, high resolution marking. Multiple marking materials may be introduced into the channel and mixed therein prior to being made incident on the substrate, or mixed or superimposed on the substrate without registration. One example is a single-pass, full-color printer.

International Classification:

H01J 4014

US Classification:

250221, 25022714

Abstract:

A microsensor including a VCSEL for use in a MEMS. By coupling the top mirror of the VCSEL to the micromechanical structure, either directly or indirectly, the motion of the micromechanical structure in response to a physical phenomenon can directly modulate the wavelength of the light emitted from the VCSEL. Also, a method for sensing and transmitting information about the configuration or motion of a mechanical structure. The method includes coupling the top mirror of a VCSEL to the mechanical structure that directly encodes information about the motion into the frequency of light emitted by the VCSEL.

International Classification:

G06F 1700

US Classification:

235381, 235375

Abstract:

Distributed market based analog control of a system of actuators and sensors. The system is comprised of one or more producing units having an output responsive to a market price and one or more input units having an input responsive to a market price. Market price information is communicated through an information channel that is encoded as measurable changes in non-electrical partitionable physical properties. Such partitionable physical properties include pressure, thermal, chemical or acoustic properties.

International Classification:

F15B 1108

US Classification:

91459, 91454

Abstract:

An actuator including a pneumatically distended elastomer membrane that is pressurized and depressurized using electrostatically actuated flap valves laminated onto a printed circuit board. The flap valves close only at zero pressure gradients and flows so that elevated closing and hold-off pressures are achieved. Fluid expelled from the elastomer membranes during collapse are vented through a wall of the actuator. An air jet object mover utilizes an array of the pneumatic actuators as valves to open and close air jet vents. A fiber optic micro-switch utilizes pneumatic actuators to position a mirror.

Abstract:

The methods, compositions and apparatus disclosed herein are of use for nucleic acid sequence determination. The methods involve isolation of one or more nucleic acid template molecules and polymerization of a nascent complementary strand of nucleic acid, using a DNA or RNA polymerase or similar synthetic reagent. As the nascent strand is extended one nucleotide at a time, the disappearance of nucleotide precursors from solution is monitored by Raman spectroscopy or FRET. The nucleic acid sequence of the nascent strand, and the complementary sequence of the template strand, may be determined by tracking the order of incorporation of nucleotide precursors during the polymerization reaction. Certain embodiments concern apparatus comprising a reaction chamber and detection unit, of use in practicing the claimed methods. The methods, compositions and apparatus are of use in sequencing very long nucleic acid templates in a single sequencing reaction.
