Provided is a mobile event-recording device contained within an airtight chassis with its internal temperature regulated according to pre-programmable operational thresholds via a controller using a temperature sensor and a solid-state heat pump attached to or proximate with the chassis. The perturbed new Normal vectors are then used to look up texels in an environment map. The low noise amplifier also includes an adjusting unit configured to adjust a time constant for reducing a third order intermodulation distortion of the superposed signal in response to a control signal. These tags are PCR-amplified, purified, concatenated into longer molecules, and then cloned and sequenced.
