Abstract: The present invention relates to a device for obtaining capacitance measurements for use in determining the relative permittivity and thickness of a pharmaceutical tablet. The invention further relates to a method of determining the relative permittivity and thickness of a pharmaceutical tablet using one or more capacitance sensors. The device and method may be part of a pharmaceutical tableting unit or a pharmaceutical tableting method.

Abstract: A method is set forth for encoding and decoding a video signal, including the following steps: encoding the signal, the encoding including separating the signal into a plurality of spatial frequency bands at different frame rates, and temporally pre-filtering at least one of the bands with a pre-filtering circuit; and decoding the encoded signal, the decoding preferably including temporally post-filtering the at least one band, and combining the bands. In a preferred embodiment temporal pre-filtering is low-pass temporal filtering with a filter cut-off in the range 1.25 to 1.75 times the temporal Nyquist limit for the frame rate of the at least one band. The temporal post-filtering is preferably low pass temporal filtering with a cut-off near the Nyquist limit.
