Abstract: A method and apparatus for calibrating a halftone imaging system is described which automatically compensates for drifts in overall system performance as well as for any substantial change in the imaging parameters. Calibration is achieved by optimizing the exposure level of the imaging system and linearizing the exposure level of the imaging system based on the determined optimized exposure level. The method and apparatus of the present invention are capable of calibrating an imaging system automatically by generating lookup tables and transfer functions without substantial operator intervention. Once calibration is achieved, subsequent imaging commands are automatically mapped to appropriate commands that produce a calibrated output image.

Abstract: Temperature control apparatus for controlling the temperature of an electrically heated moveable object such as an electrically heated rotatable drum. A temperature control mechanism, rotatably mounted in conjunction with the cylindrical drum and electrically coupled to the electrical heater, controls the temperature by controlling the flow of electricity to the electrical heater in response to control signals. A temperature sensor mechanism, rotatably mounted in conjunction with the cylindrical drum and electrically coupled to the temperature sensor, senses the temperature of the surface of the cylindrical drum and produces temperature signals indicative thereof. A microprocessor, non-rotatably mounted with respect to the cylindrical drum, controls the temperature of the electrically heated drum by generating the control signals in response to the temperature signals.

Abstract: A two-part sensor includes a power source/signal receiver and a signal generator which are physically spaced and disconnected from one another. The power source/signal receiver is encased within transparent encapsulating material and includes an annular solenoid core with an aperture, a coil around the core and a photodiode mounted in the aperture. The photodiode detects a modulated light beam received from the signal generator and produces an output information signal.

The signal generator is encased within transparent encapsulating material and includes an annular relay coil with an aperture, a coil around the core, a transducer circuit and an LED mounted within the aperture. The relay coil provides a signal generator supply potential when positioned within the magnetic field produced by the power source/signal receiver. The supply potential powers the transducer circuit and the LED.
