Abstract: In driving an AC type PDP of a matrix formation formed of lines and rows, the PDP includes: plural first and second sustain electrodes arranged on a first substrate, each extending along the line direction, the first & second sustain electrodes being in parallel and adjacent to each other; plural address electrodes arranged on a second substrate opposing the first substrate via a discharge space, each extending along the row direction; and a dielectric layer for covering the first and second sustain electrodes, wherein the method comprises: in causing a writing discharge between the first & second sustain electrodes, the step of: causing supplementally a discharge between the address electrode and the second sustain electrode, wherein the address electrode is positive with respect to the second sustain electrode; and concurrently causing said writing discharge between the first and second electrodes, wherein the first sustain electrode is positive with respect to the second sustain electrode.

Abstract: A high-sensitivity capacitive oil deterioration and level sensor includes a conductive housing member with an inner surface defining a ground electrode and conductive inner member with an outer surface defining a measuring electrode. The housing member is adapted to provide a fluidic connection between an oil container and a gap between the ground electrode and the measuring electrode. The sensor also includes electronics adapted to employ this capacitor geometry to generate signals indicative of a degree of deterioration and a level of the oil within the gap.

Abstract: A sensor assembly for measuring characteristics of motor oil in a vehicle includes a housing adapted to be mechanically coupled to a vehicle for receiving motor oil of the vehicle and at least one capacitive sensor including sensing electrodes positioned relative to the housing to measure characteristics of motor oil between the sensing electrodes. The sensing electrodes are coated with a soot build-up inhibiting coating which, in a preferred embodiment, is a silicone coating. The at least one capacitive sensor include an oil level sensor and an oil deterioration sensor in a preferred embodiment.
