A power supply includes an input component that receives power from a source and an automatic load sense (ALS) component associated with the power supply that monitors and regulates at least two or more of current and power output from the power supply. An output component that provides power from the ALS component to one or more variable load components.

Smart power supply

The present invention is the designation of one of the processors in the system as the master processor with the roll of resetting the other processors after a software crash. When a system software crash occurs, the master processor provides a reset signal that is automatically conveyed to each of the other processors to synchronize the return of the other processors back to the normal state of operation.

Single point microprocessor reset

The present invention is a multiprocessor control system that allows full job recovery after a machine power down or after a malfunction or software crash or temporary power outage. In particular, essential variables such as the state and status of the machine and the programmed job at the time of the malfunction are maintained in nonvolatile memory. This information is continually updated in nonvolatile memory. Once the control system has reset and reinitialized all the control elements after a malfunction, the control restores or downloads all the relevant variables in the nonvolatile memory to the various control elements to maintain status. In another embodiment, the essential variables are maintained in RAM locations in a master processor and saved for downloading to the control elements.

Control system job recovery after a malfunction

A display for use in conjunction with a copier. The disclosed display comprises two microprocessors for controllably displaying information on a display panel of a xerographic copier. A first microprocessor is primarily responsible for energizing alphanumeric elements to either send messages to the copier user or to prompt the user to interact with the copier. A second display is a liquid crystal display wherein selectively energizable liquid crystal elements corresponding to copier components can be rendered visible under the control of the second microprocessor. An overlay pattern can be placed above the liquid crystal display to present to the user in outline form the copier architecture with which he is interacting. This overlay can be changed as the copier configuration is changed. The electronics for controlling the display of alphanumeric allows the utilization of different fonts and/or different languages. This flexibility allows the copier to prompt, and/or display information regarding copier status in various languages without a redesign of the display unit.
