A discrete digital transceiver includes a receiver sample and hold module, a discrete digital receiver conversion module, a transmitter sample and hold module, a discrete digital transmitter conversion module, clock generation module, and a processing module. The organic light emitting diode display device includes a first flexible substrate, a second flexible substrate, a first barrier layer, a second barrier layer, an organic light emitting diode element, and a metal enclosing wall. In other aspects of the invention, a device comprises bite-actuated tooth- and gum-brushing channels and other features facilitating the variable bite-actuated release and application of a dentifrice and scrubbing. The membrane may comprise a substrate of non-ion-conducting material that is penetrated by openings, each opening providing a corresponding one of the passageways. Image data of the first and the second area is extracted from the image data read in the two-page spread mode. A pipefile having at least the same number of entries as the number of execution pipeline stages is included in the processor A pointer register is associated with each execution pipeline stage.
