Abstract: An electronic organizer is provided that incorporates an internal electronic scanner and a touch sensitive display screen to enter text and image data. The internal electronic scanner permits both machine generated text and image data to be scanned and directly entered into the electronic organizer. Hand-printed text data is also entered directly via the touch sensitive display screen using a stylus or pen. The scanned machine generated text, the scanned image data and the hand-printed text can either be preserved as an image-oriented bit map, or optical character recognition routines can be applied to the data to identify characters and convert the identified characters to computer coded text data. Data entered into the electronic organizer is arranged in a relational database format, which permits the operator to quickly and easily enter and retrieve related information between a number of different databases with a minimal amount of effort.

Abstract: A scanner with high intensity source beam, a modulator for modulating the source beam to provide a zero order beam and first order writing beam in response to an image signal input, a polygon for scanning the writing beam across a moving recording member to write images thereon, a sensor in the path of the zero order beam providing a first black beam intensity signal while scanning between pages and a second white beam intensity signal while the writing beam scans an image background area, a circuit for differencing the first and second beam intensity signals from one another to provide a composite intensity signal representing the intensity of the source beam, and a second circuit for differencing the composite beam intensity signal from an intensity setpoint signal to provide a correction signal for adjusting the rf power to the modulator to maintain a substantially constant writing beam intensity.In a second embodiment, the correction signal is determined by a successive approximation register.
