Abstract: A crystal-free radio includes an antenna; a receiver configured to communicate with the antenna; a local radio frequency (RF) oscillator configured to communicate with the receiver; and a clock circuit configured to communicate with the receiver and the local RF oscillator, the clock circuit having an electronic circuit oscillator. The local RF oscillator is a free-running oscillator. The clock circuit is configured to receive a calibration signal via a wireless network and calibrate the electronic circuit oscillator based on the received calibration signal, and the clock circuit is a crystal-free clock circuit.

Abstract: A containment and test system for extremely toxic substances includes a fume hood, a containment compartment such as glove bag or box, positioned within the fume hood, a source of a non-reactive gas to provide a stable environment within the containment compartment, an inline moisture trap coupled to the source of non-reactive gas to dry the non-reactive gas, an ion neutralizer coupled to the source of non-reactive gas to reduce static charges within the containment compartment, a staging area for preparing test samples, a balance positioned within the containment compartment, a stanchion positioned within the fume hood for holding a test animal, and decontaminating apparatus for safely disposing of any toxic substance residue.
