Carbon filters 89000-124, -126, and -128 are sold separately and keep concentrations of these chemicals below OSHA-recommended, time-weighted average levels.

Method:Using a computerized electric oculography to give a quantitative record of the TWAG(Time-weighted average gain)and SR(Saccade rate)in 67 schizophrenic patients and 37 controls.

A rolling multiple model weighted average estimation algorithm is presented for tracking the fast time varying model parameters.
