Many industrial and commercial plants, government and private research facilities, and industrial facilities perform potentially dangerous processes. Automated warning and alarm systems alert personnel to dangerous or abnormal conditions inside or near a plant so the personnel may take prompt protective action such as evacuation, co-location, or shelter in place. Such automated systems include simple fire and smoke detectors that detect the presence of fire or smoke and immediately activate a connected, audible alarm confined to a specific area of a plant. Many systems include a central hub for receiving detection signals from detectors located throughout a plant. In some systems, the central hub also is connected to a network of alarms including audible alarms — both siren-like and information-based — and visual alarms, including flashing emergency lights and textual-based information screens.

Traditional smoke opacity measurement, performed on diesel engines during regular emissions inspections, sensitive primarily to larger particles of elemental carbon, is very little sensitive to nanoparticles and to semi-volatile “organic carbon” particles. For this reason, it no longer suffices as a high emitter detection tool for modern vehicles with a particle filter or for advanced low-emissions technology where semi-volatile organic particles are the dominant fraction of particulate matter. This paper investigates the potential of common low-cost ionization type smoke detectors, produced in mass quantities for fire detection in buildings, as a tool to measure particle emissions in vehicular exhaust. Two ionization chambers were used to measure both raw and diluted exhaust of various engines powered by diesel fuel and biofuels under laboratory conditions as well as on the road. Laboratory results suggest that the ionization chamber signal correlates best to total particle length, with correlation to number and mass dependent on particle size distribution. Particle filter regeneration events were clearly discerned from the ionization chamber readings. With detection limits on the order of 0.1 mg/m3 and 106 particles/cm3 in raw exhaust, the method appears to be sufficiently sensitive for inspection of vehicles equipped with particle filters and for preliminary measurements of particle emissions from modern engines.

Smoke Particle Sizes in Low-Gravity and Implications for Spacecraft Smoke Detector Design2009-01-24687/12/2009
This paper presents results from a smoke detection experiment entitled Smoke Aerosol Measurement Experiment (SAME) which was conducted in the Microgravity Science Glovebox on the International Space Station (ISS) during Expedition 15. Five different materials representative of those found in spacecraft were pyrolyzed at temperatures below the ignition point with conditions controlled to provide repeatable sample surface temperatures and air flow conditions. The sample materials were Teflon®, Kapton®, cellulose, silicone rubber and dibutylphthalate. The transport time from the smoke source to the detector was simulated by holding the smoke in an aging chamber for times ranging from 10 to1800 seconds. Smoke particle samples were collected on Transmission Electron Microscope (TEM) grids for post-flight analysis. The smoke particle size distributions were measured using three particulate aerosol diagnostics that measure different moments of the size distribution and smoke detectors from the ISS and the space shuttle, These diagnostics were used to estimate the particle number concentration (zeroth moment), the diameter concentration (first moment) and the mass concentration (third moment), These values were combined to estimate the diameter of average mass, the count mean diameter, the geometric mean diameter and the geometric standard deviation. Even though the analysis of these data is ongoing, information from the various instruments and the calculated mean particle sizes has important implications for the design of spacecraft smoke detectors. These implications are reviewed in this paper relative to the operating principles of existing smoke detection technology, These results can be used to establish design requirements for smoke detectors for future spacecraft.

The Application of Piezoceramic Actuation to Direct Fuel Injection2003-32-00019/16/2003
With increasing demands to reduce emissions from internal combustion engines, engine manufacturers are forced to seek out new technology. One such technology employed primarily in the diesel and two-stroke engine community is direct-injection (DI). Direct injection has shown promising results in reduction of CO and NOx for both two- and four-stroke engines. While having been used for several years in the diesel industry, direct injection has been scrutinized for an inability to meet future requirements to reduce particulate matter emissions. Direct injection has also came under fire for complicating fuel delivery systems, thus making it cost prohibitive for small utility engine manufacturers. Recent research shows that the application of piezo-driven actuators has a positive effect on soot formation reduction for diesel engines and as this paper will distinguish, has the ability to simplify direct injection fuel delivery systems in general. The potential for emissions reduction and improved engine performance by use of direct injection is well documented in the literature. The current debate centers around the most efficient way to produce direct injection without having a negative effect on system complexity, cost, and performance. This work investigates the use of the newly emerging piezoceramic actuation technology to accomplish such goals. Piezoceramic actuation has become an area of increased interest in the past ten years. Having been used for many years as sensors in such applications as pressure transducers and smoke detectors, piezoceramics are now being investigated as prime movers in fuel injectors. In an effort to aid the engineering community, this paper will conduct a comprehensive review of several piezoceramic actuators and discuss the current state of the art. An existing direct-injector used on an outboard two-stroke engine is used as the benchmark in this study. The system parameters are determined experimentally and used to select the appropriate piezoceramic actuator architecture. A proof of concept device will be constructed to determine the feasibility of designing direct-injectors using piezoceramics. The experimental results will show that the piezoceramic actuator can successfully deliver the force and stroke required. The results will also show the limitations imposed on the actuation system when use of mechanical advantage is incorporated into the design.

Columbus APM Environmental Control System Overview: Space Station and APM Restructuring Consequences9413056/1/1994
This paper describes the main changes affecting the APM Environmental Control System (ECS) as a consequence of the Space Station Freedom (SSF) restructuring and Columbus APM overall reconfiguration. The main purposes of this reconfiguration are: minimize the number and complexity of the interfaces with Space Station Freedom (SSF) centralize avionics command and monitoring tasks revisit the failure tolerance concept of some ECS functions unify/standardize similar functions in the two subsystem adjust lifetime requirements and simplify maintenance concept of equipment. The APM ECS consists of the following functions: active thermal control (ATCS) passive thermal control (PTCS) atmosphere pressure and composition control air revitalization and cabin ventilation temperature and humidity control vacuum and venting nitrogen supply fire detection and suppression. The new ATCS configuration provides a cooling capability for a reduced number of P/L racks by means of its moderate loop. No modification is envisaged on the low temperature loop. Failure cases on both SSF thermal buses and APM ATCS have been considered and assessed, resulting in an optimization of the ATCS operation in off-nominal modes. Due to the adoption of a new APM launcher (ARIANE 5) instead of NSTS, the Negative Pressure Relief function is no longer required. A new cabin loop architecture is considered based on the use of three fans for air distribution in the APM thermal conditioning and air exchange with the adjacent SSF node (Intermodule Ventilation). As far as the Vacuum and Venting system is concerned, the only changes are the reduction of the connected lateral P/L racks and the deletion of the venting interface with the SSF. The same lateral P/L racks are also connected to the Nitrogen Supply system with the deletion of the relevant interface valves. The main change in the Fire Detection system concerns the new location of smoke detectors within the cabin loop. The Fire Suppression system is impacted due to the reduction of the number of enclosures requiring a fire suppression capability. Optimization in heater control has been achieved, while the decentralized valve control concept has been deleted in favour of a centralized one via Power Distribution Unit (PDU).

Development of the Flame Detector for Space Station Freedom9321067/1/1993
One of the primary safety concerns for Space Station Freedom pressurized modules is fire. Some Freedom modules are unattended for long periods of time. In other cases, enclosed, pressurized volumes are not open to crew monitoring. As a result, a fire detection system is required to continuously monitor all modules for combustion. This paper briefly reviews the overall design for the Freedom fire detection system, and the design of the two basic types of detectors: smoke and flame. The smoke detectors monitor particulates in small open areas, stand-offs, end-cones, and racks. The flame detectors survey open areas for radiation at wavelengths and intensities characteristic of combustion. Responses from detectors are evaluated by Freedom's data management system to determine the presence of combustion and to recommend appropriate action. The combination of discrete detectors and centralized processing produces a flexible fire detection system which can adapt to an evolving Space Station Freedom design or to other enclosed environments. This paper then focuses on the design, development, and testing of the flame detector. The flame detector monitors for radiation in three specific ranges of the spectrum: in a narrow band in the ultraviolet, in the visible, and in a broad band in the infrared. The ultraviolet and infrared ranges are characteristic of combustion. The visible range provides a measure of the background and is used as a discriminator to minimize false alarms. The detector provides analog outputs which are functions of the total energy received in each of these ranges. The detector also monitors for flicker, another characteristic of combustion. The design and development of the flame detector are discussed in detail. Final data from the flame detector development test are presented and discussed.
