A very low emission hybrid electric vehicle incorporating an integrated propulsion system which includes a hydrogen powered internal combustion engine, a metal hydride hydrogen storage unit, an electric motor, high specific power, high energy density nickel-metal hydride batteries, and preferably a regenerative braking system. The first unit may copy a datum of the second frame stored at a particular location in the memory to the buffer. An illumination source is removably attachable to the first lamp retainer to selectively illuminate a document held by the document holder and attachable to the second lamp retainer for storage in the storage compartment. The feed platform is at least for the greater part free from separating elements between the feeding places, i. The cabinet door is pivotally connected to both the temperature control cabinet opening and the decoration cabinet opening to seal the temperature control cabinet opening and the decoration cabinet opening. This calibration method may be used to reduce errors in the signal sources which have a linear, Gaussian, or other error distributions.
