Abstract:
An exhaust gas analyzing apparatus of a vehicle mounted type equipped with an analyzer that is configured to analyze components contained in exhaust gas includes a sampling line that is an exhaust gas flow path extending from an exhaust gas introduction terminal that is configured to introduce the exhaust gas from the outside to the analyzer; a pressure reduction source that is configured to reduce a pressure in the sampling line to a predetermined pressure; and a temperature-regulating mechanism that is configured to regulate a temperature of the exhaust gas flowing in the sampling line to be at least a first temperature. The first temperature is set to be a temperature equal to or higher than an evaporation temperature of moisture at the reduced predetermined pressure and lower than an evaporation temperature of moisture at one atmospheric pressure.
Abstract:
Systems for very early smoke detection are disclosed, including details of tube hangers that may be used to hang sampling tubes for very early smoke detection systems. The systems and components thereof may be temporarily installed in aerospace vehicles during manufacturing. The tube hangers are generally compact, allowing use in confined spaces and/or near obstructions. Tube hangers comprise a support coupling mechanism, a tube clamp, and one or more suspension arms that span between the support coupling mechanism and the tube clamp. Tube hangers may be a unitary body that defines a tube clamp, one or more suspension arms, and a support coupling mechanism. Tube clamps define a tube clamp opening generally facing away from the support coupling mechanism.
Abstract:
A system and method for in-field near infrared spectroscopy (NIRS) analysis of rubber and resin concentrations a guayule plant is provided. The system includes a wagon or other vehicle with the NIRS device mounted on the wagon. A computer or processor electrically coupled to the NIRS device is also housed within an area or extension of the wagon. During measurement of a guayule plant in the field, a guayule plant covering is placed over the guayule plant and a light shield coupled to the NIRS device is inserted into an opening on the guayule plant covering. The NIRS device is configured to perform a reading of the guayule plant within the plant covering and communicate results of the reading to the computer. A calibration equation is then preferably applied to the guayule plant readings to produce the rubber and resin concentrations of the guayule plant.
Abstract:
A method and a device for outputting a signal when there is a hazardous surface under a vehicle includes providing an optical surface sensor for determining one or more parameters of the underlying surface, a stationary-state-determining device for determining whether the vehicle is stationary or is to be brought to a standstill, and an output device that outputs a signal if the underlying surface has been determined to be hazardous on the basis of the parameter(s), and the vehicle is stationary or is to be brought to a standstill.
Abstract:
In one embodiment, a method and system is provided for detecting target materials using a combination of stroboscopic signal amplification and Raman spectroscopy techniques.
Abstract:
An optical detection system per motor-vehicles, suitable to detect the condition of the road surface on which the vehicle is travelling, comprising a photodetector unit composed of a camera having a matrix of pixels composed of photodetectors based on a photosensitive material suitable to detect both radiations in the visible and near infrared, i.e. having a wavelength comprised between 380 and 900 nanometres, and radiations in the short wavelength infrared, i.e. having a wavelength comprised between 900 and 1700 nanometres.
Abstract:
A system for sampling and analyzing a material located at a hazardous site. A laser located remote from the hazardous site is connected to an optical fiber, which directs laser radiation proximate the material at the hazardous site. The laser radiation abates a sample of the material. An inductively coupled plasma is located remotely from the material. An aerosol transport system carries the ablated particles to a plasma, where they are dissociated, atomized and excited to provide characteristic optical reduction of the elemental constituents of the sample. An optical spectrometer is located remotely from the site. A second optical fiber is connected to the optical spectrometer at one end and the plasma source at the other end to carry the optical radiation from the plasma source to the spectrometer.
Abstract:
A soil test apparatus for field use comprises structure adapting the apparatus for transport over a field for testing the soil thereof; an infrared radiation generator for producing infrared radiation at a plurality of predetermined wavelengths, an elongate light carrying member coupled to the infrared radiation generator and extending therefrom for directing infrared radiation onto the soil; and a light detector for detecting infrared radiation reflected from the soil and for producing corresponding electrical signals.
Abstract:
A deployable measurement system for analyzing a rail of a railroad track includes a housing, a reflecting assembly coupled to the housing, a movement assembly coupled to the housing, and an optical measurement system disposed within the housing. Both the housing and the reflecting assembly are moveable between a stored position and a deployed position. The movement assembly includes a deployment assembly that moves the reflecting assembly from the stored position to the deployed position, and a retraction assembly that moves the reflecting assembly from the deployed position to the stored position. The optical measurement system emits and receives light. The reflecting assembly reflects the emitted light toward the rail. The reflecting assembly reflects light reflected off of the rail toward the optical measurement system. The light received by the optical measurement system is used to measure parameters related to the rail.
