Lawless, P. (2003). Portable air sampling apparatus including non-intrusive activity monitor and methods of using same. (U.S. Patent No. 6502469). http://patft.uspto.gov/netacgi/nph-Parser?patentnumber=6502469
Portable air sampling apparatus and methods are provided for passively and/or intermittently sampling air in the breathing zone of a person over extended periods of time. The presence of airborne contaminants can be monitored, as well. Air sampling system performance can be continuously measured and recorded within a data logger. In addition, physical activity levels of a person wearing a portable air sampling system can be continuously monitored and recorded within the data logger. An input device communicates with the data logger and allows a user to store information about his or her personal activities in the data logger. A receiver in communication with the data logger can receive data from remotely located communications devices, such as a Global Positioning System (GPS) signals. A transmitter in communication with the data logger can transmit data from the data logger to remotely located communications devices.
