Abstract: Systems and devices for collecting time and space resolved air samples are disclosed. In some embodiments, the systems and devices include the following: a housing including an air inlet; a pump positioned to draw air from outside the sampler and into the housing; electronically controllable valves positioned within the housing for receiving air from the pump; air sampling filters for receiving air from the valves; a printed circuit board including a microcomputer, a global positioning satellite tracking device, and programmable memory, the microcomputer being configured to control the valves to allow air to flow to particular air sampling filters to collect an air sample, the microcomputer being configured to record time data and positioning data from the global positioning satellite tracking device simultaneous to collecting the air sample, the data being stored in the programmable memory; and a power source to provide power for the sampler.

Abstract: The invention includes a device for collecting travel-related data for a motor vehicle. The usage data includes such data as a start time and date of a trip, a beginning odometer reading, a category code indicating the purpose of the trip, a sub-category code further indicating the purpose of a trip, and maintenance information for the vehicle. Data collection begins when the ignition system of the vehicle is activated. The invention includes means for downloading the collected data to an external device, such as a microcomputer.
