摘要： A method for operating a sensing device. The method comprising: a sensor film having an electrical resistance that is adapted to change in response to the presence of a predetermined condition; detecting the presence of the predetermined condition; measuring the electrical resistance of the sensor film at a first time; measuring the electrical resistance of the sensor film at a second time; determining a rate of change of the electrical resistance between the first time and the second time; and comparing the rate of change of the electrical resistance against a threshold value.

摘要： A thermo-anemometer-type fluid flow rate sensor design and a method for its operation that overcome the response time limitations of prior known fluid flow rate sensors is disclosed. The fluid flow rate sensor includes a probe having a detection module adapted to change condition in response to the presence of the flow of the fluid, a control module that is electrically connected to the probe that monitors the condition of the detection module over time (e.g., a temperature), determines a rate of change of that condition over time, and generates an output that is indicative of the rate of flow of the fluid, and a I/O module connected to the control module to provide a means for communicating the output of the control module to another device or a user.
