    • Chemical and biological detector systems, devices and apparatus. Such devices may be portable and wearable, such as badges, that are analyte-general, rather than analyte-specific, and which provide an optimal way to notify and protect personnel against known and unknown airborne chemical and biological hazards. The devices of the present invention are advantageously low-cost, have low-power requirements, may be wearable and are designed to detect and alarm to a general chemical and biological threat. A sensor device of the present invention in one embodiment includes two or more sensor devices, a processing module coupled to each of the sensor devices and configured to process signals received from each of the two or more sensor devices to determine an environmental state; and a communication module that communicates information about the environmental state to a user.

    • A vapor sensing device that is sufficiently small and lightweight to be handheld, and also modular so as to allow the device to be conveniently adapted for use in sensing the presence and concentration of a wide variety of specified vapors. The device provides these benefits using a sensor module that incorporates a sample chamber and a plurality of sensors located on a chip releasably carried within or adjacent to the sample chamber. Optionally, the sensor module can be configured to be releasably plugged into a receptacle formed in the device. Vapors are directed to pass through the sample chamber, whereupon the sensors provide a distinct combination of electrical signals in response to each. The sensors of the sensor module can take the form of chemically sensitive resistors having resistances that vary according to the identity and concentration of an adjacent vapor. These chemically sensitive resistors can each be connected in series with a reference resistor, between a reference voltage and ground, such that an analog signal is established for each chemically sensitive resistor. The resulting analog signals are supplied to an analog-to-digital converter, to produce corresponding digital signals. These digital signals are appropriately analyzed for vapor identification.
    • 一种气体感测装置,其足够小且重量轻以便手持式,并且也是模块化的,以便允许装置方便地适用于感测多种特定蒸气的存在和集中。 该装置使用包含样品室的传感器模块和位于可拆卸地承载在样品室内或附近的芯片上的多个传感器来提供这些益处。 可选地,传感器模块可以被配置为可释放地插入形成在设备中的容器中。 蒸气被引导通过样品室,于是传感器响应于每个传感器提供电信号的明显组合。 传感器模块的传感器可以具有化学敏感电阻器的形式,其具有根据相邻蒸汽的特性和浓度而变化的电阻。 这些化学敏感电阻可以分别与参考电阻串联在一个参考电压和地之间,从而为每个化学敏感电阻建立一个模拟信号。 所得到的模拟信号被提供给模数转换器,以产生相应的数字信号。 适当地分析这些数字信号以进行蒸气识别。
