  • Patent number: 7137299
    Abstract: A proof mass is suspended in a cavity in a housing. The proof mass moves along a sensing axis in response to linear acceleration. Elastic support members are connected between the proof mass and the housing and are arranged to exert a reaction force on the proof mass in response to displacement of the proof mass along the sensing axis. An optical fiber is connected between the proof mass and opposite sidewall portions of the housing such that displacement of the proof mass along the sensing axis elongates a first portion of the optical fiber and shortens another portion. An optical signal source provides a broadband optical signal input to the optical fiber. A fiber optic Bragg grating is formed in the optical fiber and arranged to reflect a portion of the optical signal. Acceleration of the proof mass modulates the wavelength of the reflected optical signal.

  • Publication number: 20060246234
    Abstract: A photomask assembly is disclosed having a photomask substrate and a composite pellicle frame that includes both a metallic frame component and a scavenger component. The metallic frame component has a cross-sectional thickness of at least 100 micrometers in all directions, and the volume percentage of the scavenger component relative to the overall volume of the composite frame is in the range of 0.1 to 95%. The scavenger component has a gas permeability to oxygen or nitrogen greater than about 10 ml·mm/cm2·min·MPa, an average pore size between 0.001 and 10 micrometers, and a pore surface area greater than 10 m2/g. This configuration enables the pellicle frame to have sufficient strength to withstand stresses encountered during normal use, yet also to have the capability of scavenging impurity molecules from the space adjacent to the photomask substrate.

  • Publication number: 20060219266
    Abstract: A method for the on-line cleaning of a heat exchanger used with petroleum process fluids which create coke deposits of asphaltenic origin on the exchanger tubes. The asphaltenes are removed by re-dissolution in a solvent oil of high solubility power for the asphaltenes. Certain asphaltenic crudes are useful as solvents in view of their chemical similarity to the asphaltene coke precursors; also useful are refined petroleum fractions such as gas oils which are also characterized by their solvency for asphaltenes. The solvent oil may be admitted to the heat exchanger following withdrawal of the process fluid and then allowed to soak and dissolve the asphaltene coke precursors after which the resulting solution may be withdrawn and the exchanger returned to use without being at any time disconnected from its associated process unit.

  • Publication number: 20060042661
    Abstract: A method for removing sludge from a petroleum storage tank is based on a two-step approach utilizing solvent extraction to dissolve organic components of the sludge followed by water wash to remove inorganic materials. Sludges contain both organic-based solids (e.g., waxes and asphaltenes) as well as inorganic-based solids (known to exist as salts such as chlorides, carbonates, and oxides). The organic components of the sludge are dissolved using petroleum-based solvent streams that have been identified to possess high solvent power. The dissolved material can then be processed and recovered in the refinery using conventional refining operations. A water wash following removal of the organic materials is effective to remove the inorganic materials that can then be disposed of without the complications of the having to treat the oily organics along with them. A beneficial part of the method includes mixing and heating to improve the dissolution of soluble materials in both steps of the process.

  • Publication number: 20060009699
    Abstract: A medical blood pressure transducer that provides an identifier to a monitor that conveys characteristics of the transducer. The monitor can use the information to decide whether to function, or in calibration of the system. The transducer may be part of a disposable blood pressure monitoring system, and may include two transducers closely-spaced to provide two separate but identical outputs. In this way, the transducer may be connected to both a patient monitor and a cardiac output monitor at the same time measurements from a single line can be simultaneously supplied to two separate monitoring devices (for example a patient monitor and a cardiac output monitor). The identifier for the transducer may be circuitry, specifically a resistance/capacitance (RC) combination that possesses a characteristic time constant.

  • Publication number: 20050211483
    Abstract: An engine air intake system including an engine air intake device and a plenum cooling compartment that is separate from the engine compartment by a baffle. The plenum cooling compartment is formed by the baffle, side doors, a fan door and a floor and contains a heat exchanger. A fan draws outside ambient air into the plenum cooling compartment, via perforations in the top and side doors, and out of the plenum cooling area via the heat exchanger. The cooling compartment is designed such that a distance between the heat exchanger and the baffle provides a gap from which the engine air intake device removes ambient air as a source for engine air. An option is provide for the system to withdraw outside ambient air from an area external to the plenum cooling compartment in high debris environments. The engine air intake system cleans the air before supplying it to the engine.

  • Publication number: 20050101699
    Abstract: An encapsulant for use with opto-electronic devices and optical components incorporates a filler made from a glass that has been processed into particle form and heated to a predetermined temperature for a predetermined time, along with an epoxy having an index of refraction matched to that of the glass and heated to a predetermined temperature for a predetermined time, to prevent settling of the filler particles after mixing the filler particles with the epoxy, and thereby obtaining uniform dispersion of the particles within the epoxy. The encapsulant provides for high light transmittance, and its coefficient of thermal expansion can be varied by varying the amount of filler without substantially altering the optical properties of the encapsulant. The coefficient of thermal expansion variation within the encapsulant preferably is less than 30%, due to uniform dispersion of the filler particles within the epoxy.

  • Patent number: 6826326
    Abstract: In tunable systems, during a tuning cycle, express channels or wavelengths are dropped as the system sweeps through its free spectral range (FSR) before stopping at the desired wavelength to be dropped. This is disadvantageous as the data information in the express wavelengths suffers a hit or momentary increase in bit error rate (BER). Techniques for eliminating or at least minimizing interference to those channels or wavelengths are disclosed. According to one aspect of the present invention, the wavelength selection to be dropped is done “off-line” and does not affect the express channels. An optical reference source is used to set up and tune a drop filter. Once the filter is set to the appropriate dropping wavelength, a secondary filter is scanned to cause the channels to be shunted to the drop filter. If the wavelength of a signal and the drop filter matches, the signal is dropped.

  • Patent number: 6795610
    Abstract: Techniques for adding and dropping a wavelength or band using two individual optical paths are disclosed. The two individual optical paths are configured to maintain one path active while the other is in stand-by setup or tuning mode. While one optical path is adding and dropping a wavelength, the other optical path can be calibrated for a new wavelength. When an optical switch switches from one path to another, a new wavelength to be added and dropped is effectuated.

  • Patent number: 6751375
    Abstract: Techniques for adding and dropping a desired band, channel or wavelength by calibrating optical tunable devices precisely for the desired wavelength are disclosed. An optical path is formed and includes two tunable devices and a circulator coupled between the two tunable devices so as to prevent possible interference to channels and wavelengths passing through the two tunable devices. A small portion of a dropped signal is used as a reference signal to be introduced into the optical path. A reflected signal of the reference signal is coupled out of the optical path for determination of control signals most suitably for the two tunable devices so as to achieve an accurate control over an absolute wavelength of the tunable devices.

  • Patent number: 6514454
    Abstract: A sol-gel process for producing dry porous gel monoliths, e.g., silica glass monoliths, in which the successive process steps of gelling, aging and drying all occur within a mold formed of a selected porous material, e.g., graphite. The mold is inert to the gel solution and it has sufficient strength to withstand the temperatures and pressures encountered during the process. The mold and gel thereby can remain within a sealed autoclave during these process steps, and mechanical handling of the mold and the gel are minimized. This substantially enhances the process' efficiency. Alternatively, the mold can have a non-porous inner skin to enhance ease of cleaning of the mold, and of removal of the gel.
