Patent number: 6927394Abstract: 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.Type: GrantFiled: January 13, 2003Date of Patent: August 9, 2005Assignee: Fire Sentry CorporationInventors: Owen D. Parham, David A. Castleman

Publication number: 20030036761Abstract: 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.Type: ApplicationFiled: July 3, 2002Publication date: February 20, 2003Inventors: Crista Smothers, John Schneider, Ed Austin, Ajit Mishra, Mark Gosney, Anthony James, David Castleman, Mark Hamby, Julie Bearcroft, Jeff Holbrook, Jeff Schryver, Michael Cooper

Patent number: 6518574Abstract: 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.Type: GrantFiled: August 25, 2000Date of Patent: February 11, 2003Assignee: Fire Sentry CorporationInventor: David A.

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.Type: GrantFiled: August 25, 2000Date of Patent: February 4, 2003Assignee: Fire Sentry CorporationInventors: David A.
