Abstract: A circuit includes a first analog to digital converter configured to convert an analog voltage sample of a rechargeable power source into a digital voltage value, a second analog to digital converter configured to convert an analog current sample of the rechargeable power source into a digital current value, a charge state controller configured to determine a charge state of the rechargeable power source based on the digital voltage value and the digital current value, and a communication interface configured to output a computer-readable indication of the charge state. The charge state controller is further configured to receive pregenerated voltage values and pregenerated current values, and determine a simulated charge state of the rechargeable power source based on the pregenerated voltage values and the pregenerated current values. The communication interface is further configured to output a computer-readable indication of the simulated charge state.

Abstract: A multifunction printer includes: a printing apparatus; a scanning apparatus; a network connection; an embedded web server for monitoring or administering the multifunction printer through web pages that are accessible to a web browser on a client station through the network connection; and a read only memory that is configured to store computer game or educational software, wherein the embedded web server is configured to provide one or more computer games or learning activities to one or more client stations over the network

Abstract: A multifunction printer includes a printing apparatus; a scanning apparatus; a network connection; an embedded web server for monitoring or administering the multifunction printer through web pages that are accessible to a web browser on a client station through the network connection; a read only memory; and a photo editor application stored in the read only memory, wherein the photo editor application is configured to provide a browser-based user interface via the embedded web server for a user to view one or more images or perform editing tasks on the images.

Abstract: A method of operating a scanning apparatus including a transparent platen, a memory, a lid to cover the transparent platen, and a door in the lid, the method includes exposing a portion of the transparent platen through the door in the lid; placing a user identifier into the door in the lid; providing a user identification initiation signal; emitting light from a light source to illuminate the exposed portion of the transparent platen; moving a photosensor array to scan the user identifier through the exposed portion of the transparent platen; providing a digitized image of the user identifier from the scan by the photosensor array; comparing the digitized image to a stored pattern; and authorizing a function of the scanning apparatus if it is determined that the digitized image of the user identifier adequately matches the stored pattern.

Abstract: A scanning apparatus includes a transparent platen on which an item can be placed for scanning; a light source configured to emit light through the transparent platen to reflect off the item; a photosensor array that is movable to receive light reflected from successive portions of the item and convert the reflected light into electrical signals; a controller for providing digitized data from the electrical signals to form a digitized image of the item; and a lid including a first position such that the lid covers the transparent platen; a second position such that the lid does not cover the transparent platen; and a door that is configured to expose a portion of the transparent platen when the lid is in the first position.
