Abstract: A memory module is interposed between a host and a disk drive. The memory module includes a solid-state nonvolatile memory used for caching data sent by the host for storage in the disk drive. Caching takes place under the control of a memory controller in the memory module and may be transparent to the host. The disk drive may remain spun-down when data is cached, saving power. The destination for host data may be determined based on desired speed, power consumption and expected need for that data. A host may send specific commands to the memory module to enable additional functions.

Abstract: A digitized video system having a processor and a video memory.

Abstract: A method for calibrating a printing system using a spatial light modulator. The spatial light modulator is an array of individually activated elements, all of which are set in a predetermined state, such as the ON state. Light is then directed onto the array and the resultant light passed into the printing system from the modulator is monitored by a sensor. Discrepancies between the light expected and received at the sensor are used to adjust the operation of the modulator to compensate for stuck or non-responsive pixels.

Abstract: An electrophotographic subsystem (130) with on-board monitoring and adjusting capabilities. The subsystem contains a photoreceptor, at least one toner dispenser, a light sensor and a processor. The processor monitors either light received from a light-imaging subsystem which is in the system into which the EP subsystem is inserted, the wear on the photoreceptor, or the toner's composition and amount, or all of the above processes. The processor then sends information either via controllers or directly to various subcomponents as operating parameter settings or instructions.

Abstract: A toner dispenser with on-board intelligence. The toner dispenser includes a reservoir of toner material and memory that stores the characteristics and amount of that toner material contained within. A coil resides inside the reservoir to allow the system into which the dispenser is inserted to vibrate the coil. This accomplishes both a churning of the toner, and the back-EMF of the coil can be measured to calculate the amount of toner remaining. The toner dispenser has communications capability that allows it to send the information contained therein to a system processor of the system into which it is inserted.

Abstract: An intelligent printing system (110). The overall system has a light-imaging subsystem (120), an electrophotography subsystem (130) and a printing substrate subsystem (140). The system processor (126) monitors all of the characteristics of the system, including toner content and quantity, photoreceptor wear and usage, heat of the fuser, quantity of printing substrates remaining, power of the light source, and profile of a spatial light modulator. The monitored processes are used to adjust the printing process so that the maximum print quality is achieved. Additionally, the information received assists in maintaining the highest level of quality functioning of the system through the maintenance cycle.

Abstract: A digital video system including a light source and a spatial light modulator system. Varying intensities of light to achieve gray shades either with a monochrome system or within each color can be accomplished in several ways. The intensity of the light source itself can be modulated to provide variation, the spatial light modulator elements can have their states in which light is directed to a surface to form a pixel modulated, or both.
