Abstract: The present disclosure provides a radio and method for automatically adjusting, in response to ambient noise, the volume setting of a radio. The radio comprises a microphone for receiving ambient audio and generating a microphone signal; a codec for receiving the microphone signal and generating a processor signal representative of the ambient audio; and processor circuitry operable to receive the processor signal, determine an ambient audio level in response to the processor signal, and determine an adjusted radio volume to generate a radio volume control signal, wherein the adjusted radio volume is determined by calculating a difference between a baseline volume level and ambient audio level and adding a current volume level setting, wherein the codec is also operable to receive the radio volume control signal and generate an output signal to adjust the radio volume setting to maintain a net difference between the adjusted radio volume and ambient audio.

Abstract: An air sampler includes a stand adapted to support sample enclosures at spaced-apart locations. A multiposition valve is mounted to the stand. The multiposition valve has a plurality of inlet ports and an outlet port selectively fluidly coupled to any of the plurality of inlet ports. A plurality of inlet lines connects the sample enclosures to the inlet ports. A concentrator trap mounted on the stand and coupled to the outlet port concentrates selected constituents from one of the sample enclosures.

Abstract: An air sampler includes a stand for supporting a plurality of sample enclosures from which samples can be randomly and selectively obtained. In a first embodiment, a bracket adjustably fixed to the stand supports each of the sample enclosures. In a second embodiment, an inlet line fluidly couples each of the sample enclosures to a valve carried by the stand. The inlet line has a flexible portion adjacent the end coupleable to the sample enclosure to allow limited misalignment between the sample enclosure and the stand.
