A remote emissions sensing system is provided with NOdetection capability. First, a reading of the ambient NOconcentration is taken just prior to each vehicle passing through the system. This measurement accounts for any ambient NOconcentration that may be lingering from the exhaust of a previous vehicle. Next, the system takes a blocked reading when the vehicle is located in the path of the beam. This reading accounts for any ambient or system noise that may exist. Finally, the system takes a reading of the exhaust plume as the beam passes through the plume. A processor determines the portion of the reading due to the exhaust plume by subtracting the ambient and blocked readings from the exhaust plume reading. As a result, a more accurate exhaust concentration reading is provided. Additionally, the system may process exhaust plume readings only in a predetermined wavelength band associated with the known absorption spectrum of NOso that data points for which there is no significant absorption of NOmay be eliminated.

Apparatus for obtaining the speed and acceleration of a motor vehicle in which the speed and acceleration are used in combination with exhaust emissions data obtained from the motor vehicle to analyze information about the pollutants being dispersed into the air by the motor vehicle. The apparatus includes a first radiation source producing a visible laser beam received by a first detector and a second radiation source producing a visible laser beam received by a second detector. The first and second radiation sources are arranged along the roadway with a known spacing and at a height so that the visible laser beams are interrupted by the front and rear wheels of the motor vehicle as it passes along the roadway. The detectors provide output pulses indicating whether the visible laser beams are interrupted and the time of the occurrence of each of the pulses is measured and recorded. An analyzer then calculates the speed and acceleration from the known spacing distance and the stored time measurements.

An apparatus and method for measuring pollutants in a vehicle exhaust by remotely sensing hydrocarbons and nitric oxide using ultraviolet light, and measuring carbon dioxide and other pollutants using infrared light. A collimated beam of ultraviolet and a near-infrared light is propagated across the road through the exhaust plume of a vehicle. After the light beam has passed through the exhaust, a retroreflector reflects the light beam back. A beam splitter passes the infrared light to an infrared detector and deflects the ultraviolet light to an ultraviolet spectrometer. The ultraviolet spectrometer produces ultraviolet signals representative of the amount of hydrocarbons and nitric oxide in the vehicle exhaust. The infrared detector produces an infrared signal representative of the amount of carbon dioxide and other pollutants in the exhaust plume. The spectrometer and detector send the respective signals to a processor for calculation of the amounts of pollutants in the exhaust. A camera is used to take a picture of the license plate of a vehicle that emits too many pollutants.

A remote emissions sensing system and method for sensing exhaust emissions from motor vehicles is provided where the system determines the opacity of an exhaust plume. The system comprises a radiation source that emits radiation which is passed through the exhaust plume of a motor vehicle to one or more detectors arranged to receive the radiation. A processor calculates the difference between the intensity of source radiation and the intensity of the radiation received by the detectors in first and second detection bands. The intensity difference in the second detection band measures exhaust opacity. If the exhaust opacity exceeds a predetermined level, the emissions data from other detection bands may be flagged as suspect or discarded. Alternatively, for a diesel powered vehicle, the exhaust opacity determination can be validated by a measurement of carbon monoxide in the exhaust plume.

A data storage cartridge comprises data storage media configured to store data for read and/or write access, wherein the data may be arranged in a plurality of partitions; and a plurality of cartridge memories. A control system, for example of a data storage drive, is configured to allocate at least portions of capacity of the data storage media to cartridge memories of the data storage cartridge; and to provide information defining the allocated portions of capacity to the cartridge memories. Each of the cartridge memories may have a separate user and thus provide access for that user to separate partitions.

A rotary switch rotates about an axis which is at acute angles to a lower cartridge surface and a cartridge end so that a first display surface and a second display surface may be independently accessed by disparate components residing in disparate planes. The display surfaces are generally orthogonal to each other and can have multiple facets, with each facet containing a subset of information. To aid this optical interrogation, the display surfaces may be generally orthogonal to the disparate interrogating components.
