Abstract: Disclosed systems include a self-contained electroencephalogram (EEG) recording patch comprising a first electrode, a second electrode and wherein the first and second electrodes cooperate to measure a skin-electrode impedance, a substrate containing circuitry for generating an EEG signal from the measured skin-electrode impedance, amplifying the EEG signal, digitizing the EEG signal, and retrievably storing the EGG signal. The patch also comprises a power source and an enclosure that houses the substrate, the power source, and the first and second electrodes in a unitary package.

Abstract: A motorized ladder rack for loading or unloading a ladder on a vehicle is provided. The motorized ladder rack comprises a stationary front cradle, a pivotable and extendable rear cradle and a side rail. The rear cradle includes a motorized drive assembly which may be remotely controlled. The front and rear cradles are secured to the vehicle. The front cradle includes a support member, front and side guides removably secured to the support member and a side stop removably secured to the support member. The side rail is secured to the front and rear cradles and extends therebetween. The ladder rack is movable between a first position and a second position by activation of the motorized drive assembly.
