  • Patent number: 7887537
    Abstract: An external fixation system having a fixation component (20) comprising: a) a first capture member (24) adapted to capture a second element (26) of an orthopedic fixation system; and (b) a second capture member (22) adapted to capture a second element (28) of an orthopedic fixation system and coupled to the first capture member such that the coupling (86,94,110) allows the first capture member and the second capture member to rotate about three axes relative to each other element and move along that axis; wherein the coupling is adapted to secure the first and the second capture members from rotation with an activation (100); and wherein the second capture member is adapted to capture the second element by snapping onto the second element from substantially perpendicular to longitudinal axis of the second element

  • Patent number: 6927394
    Abstract: A process and system for flame detection includes a microprocessor-controlled detector with a first sensor for sensing temporal energy in a first optical frequency range, and a second sensor for sensing temporal energy in a second optical frequency range. The temporal energy sensed in the respective first and second optical frequency ranges are transformed into respective first and second spectra of frequency components. A compensated spectrum of frequency components is generated by performing a frequency bin subtraction of the first and second spectra of frequency components. The compensated spectrum represents the energy emitted from the environment with energy emitted from false alarm sources. An average amplitude and centroid of the compensated spectrum are obtained and used to determine if a monitored phenomenon represents an unwanted fire situation.

  • Publication number: 20030036761
    Abstract: This invention relates to methods, devices, and systems for preventing complications, including for example, infection associated with any percutaneous or external fixation of bones by placing a pharmacological sleeve over an external fixation element. The pharmacological sleeve may be comprised of a polymer sleeve having one or more internal splines along at least part of the inner surface of the sleeve. The sleeve may be suffused or coated on any or all surfaces with a pharmacological coating which allows accumulation of drugs in the tissue surrounding the external fixation element, thereby reducing potential complications.

  • Patent number: 6518574
    Abstract: A process and system for flame detection includes a microprocessor-controlled detector with an array of sensors for sensing radiant energy from a fire or other heat source. A wide band infrared sensor is used as the primary detector, with near band and visible band sensors serving to detect false-alarm energy from nonfire sources. A narrow band sensor, such as a 4.3-micron sensor, is also employed in the sensor array, and assists in the detection of hydrocarbon fires. Digital signal processing is used to analyze sensed data and discriminate against false alarms. A multistage alarm system can be provided, which is selectively triggered by the microprocessor. Spectral recording and analysis of prefire data is provided for. The detector can be housed in an enclosed, sealed, removable, plastic housing that may include an integral plastic window lens.

A narrow band sensor, such as a 4.3-micron sensor, may also be employed in the sensor array, and assists in the detection of hydrocarbon fires. Digital signal processing is used to analyze sensed data and discriminate against false alarms. A modulation index of one of the sensors (preferably the wideband IR sensor) is calculated by the microprocessor using measurements of the signal extremes (i.e., maxima and minima). A fire situation is not declared unless the modulation index falls within a prespecified range, such as between 5% and 85%. A multistage alarm system can be provided, which is selectively triggered by the microprocessor.
