摘要: Indirect airflow measurement through breath-operated device is accomplished by incorporating an airflow sensor into the inhaler device along a low resistance channel disposed away from the exhaust chamber of the device and having an input port in airflow communication with a low resistance channel and output input port and low resistance channel are formed in the main housing body of the device, and further incorporating an output port formed near the exhaust changer near the mouthpiece assembly, the output port also in airflow communication with the low resistance channel. A method of measuring airflow in an inhalation device is also described that measures air flowing through the low resistance channel. Another aspect of the invention provides a method that allows for the closure of the devices' airflow ports, by allowing for the rotation of the mouthpiece assembly from open to closed positions relative to the inhaling device's main housing body and towards handle assembly.

摘要: A multi-gas/gas-mixture or liquid flow sensor apparatus utilizing a specific media calibration capability. The flow sensor can be coupled with an Application Specific Integrated Circuit (ASIC) that incorporates a signal conditioner and a memory module. The signal conditioner provides a high order calibration and signal processing of flow signals from the sensor to a processed signal output representative of the flow. The processed signal output can be stored in the memory module. A correction factor can be calculated and stored in the memory module in response to the stored values of the processed signal output, which tends to linearize the relationship between the flow rate and the processed signal output of a measuring system. The correction factor and/or the processed signal output provided by the signal conditioner can be utilized by the measuring system.

摘要: A vapor sensor is disclosed, which includes a substrate containing a sensing element, wherein the substrate is located proximate to a sleeve portion which covers and protects the sensing element. The vapor sensor also includes a vapor filter or permeable membrane affixed to an end of the sleeve portion, wherein the end of the sleeve portion is located opposite the sensing element. A housing and a cover are also provided, such that the housing retains the substrate and the cover snaps onto the housing. The housing itself includes walls from which a hole is formed through which vapors may pass. The vapor sensor can be mounted to a gas water heater in such a manner as to reduce air flow to the sensing element and prevent tampering of the vapor sensor unit itself.

摘要: A thermal liquid flow sensor and method of forming same. The sensor has a substrate and one or more sensing elements, disposed on the substrate, for sensing a property of a liquid. The liquid flow sensor, which can be for example a microsensor having a microbrick® structure, has a hydrophilic layer which is disposed on the substrate and covers the sensing element(s). The hydrophilic layer is preferably formed from a spin on glass material, such as for example a silicate or phosphosilicate. A silicon nitride layer can be disposed on the sensing element(s) and interpose the substrate and the hydrophilic layer. The silicon nitride layer can be oxidized, for example, by means of plasma oxidation or oxygen ion implantation so to form the hydrophilic layer thereon. A variety of other hydrophilic compounds can be utilized to form the hydrophilic layer such as, gold, palladium and diamond like carbon.
