Abstract: A tamper proof transdermal alcohol content monitoring device is made up of analog and digital sides which are securely attached to the human subject to be monitored. The analog side has a sampling circuit which draws a measured insensible skin perspiration sample from the skin of the subject and measured with an electrochemical fuel cell. A distance measurement of the device from the skin of the subject and temperature of the sample are monitored along with the transdermal alcohol content, and converted to digital signals which are transmitted to a modem when the monitor is in proximity to the modem. The signals are stored in the modem and uploaded to a central monitoring station. Automatic alerts may be sent from the central monitoring station to a supervising agency. The supervising agency may also access the information through secured dedicated websites via the Internet.

Abstract: Air sampler with integrated airflow sensing. The air sampler according to at least some embodiments includes an air mover that is operable to move air over a sampling media. An integrated airflow sensor is in fluid communication with the air mover. The air mover operating speed can be adjusted, in example embodiments, by either a feedback control mechanism that is connected to the air mover and the integrated airflow sensor, by user input, or by a combination of the two. The feedback control mechanism adjusts the operating speed of the air mover in response to signaling from the integrated airflow sensor in order to maintain an actual airflow in accordance with a stored, target value. The feedback can, in at least some embodiments, compensate for obstructions, environmental variables, variations in the power supplied to the air mover, and the like.

The measurements are converted to digital signals which are transmitted from the bio-information unit to a modem when the bio-information unit is in proximity to the modem. The signals are stored in the modem and uploaded to a central monitoring network. Automatic alerts may be sent from the central monitoring network to a treatment provider. The treatment provider may also access the information through secured dedicated websites via the Internet.

Abstract: A particle collector comprises a housing defining an enclosed chamber. An inlet opening in the housing provides fluid communication between a source of gas and particles and the chamber and an outlet opening provides fluid communication between the chamber and the exterior of the housing. The outlet opening is connected to a pump for drawing gas and particles through the housing from the inlet opening to the outlet opening. A collecting member having an adhesive on at least a portion of the surface is disposed in the chamber between the inlet opening and the outlet opening. The adhesive surface of the collecting member is positioned adjacent to the inlet opening. When gas and particles are drawn through the housing, the inlet opening directs a stream of gas and particles at the surface of the collecting member.

Abstract: A fault distance indicator (FDI), locates a fault in a power line by modeling pulses of reflected travelling wave signals which are generated from electrical arcs that occur as a result of the fault. Open loop power distribution circuits are arranged in two halves, each half comprising a circuit length from the overhead feed point to an open point with transformers and cable sections located along the circuit length. An FDI is inserted in each half of the loop. The FDI device monitors the circuit using an antenna which receives radio-frequency signals emitted by line faults and records the signatures of these faults. When the “trouble crew” arrives at the scene the recorded signature is downloaded to a portable PC via a radio, infra-red or other telemetry link. The downloaded data is analyzed first to generate a model of the reflected travelling wave signal and then parameters of the model are adjusted to minimize differences between the model and the actual data.
