The present disclosure provides a method of modifying a user interface on a display relative to a user, comprising: detecting a position of a user's eyes relative to a user interface (UI) viewing surface, wherein the detecting includes sensors selected from the group consisting of proximity sensors, web cams, and face recognition scanners; wherein the detecting further includes detecting the position of the user's eyes relative to the user interface; adjusting the UI's viewing surface for altered viewing based on the position of the user's eyes; and, wherein the adjusting comprises a software algorithm for switching on and off semi-transparent pixels in the UI viewing surface for viewing the UI by the user at a viewing angle from about 20 degrees to about 90 degrees.

User interface panel

A device including a selectively positionable user interface that automatically repositions based on a user action, such as an office machine equipped with a user interface that is configured to tilt from a first position to a second position when a document handler is moved from an open position exposing the glass platen to a closed position, and then to return to the first position when the document handler is moved from the closed position to the open position.

Auto-positioning user interface based on user activity

A method of configuring a printing system includes providing a document key having an initial image and providing a printing system that includes a memory storing a first system setting. The method also includes scanning the document key and validating the initial image. The method can optionally include marking a first overlay image over at least a portion of the initial image, scanning the document key, and verifying the marking of the first overlay image thereon. The method also includes configuring or permitting the configuration of the printing system after the initial image has been validated or the marking of the first overlay image on the initial image has been verified. A printing system that is capable of being configured using the document key is also included.

Printing system configurable using a document key

A circuit and method for generating an electrical alternating current power signal in which the alternating current signal is dropped once at a non-zero crossing point in every 540 plus N degrees, where N is a non-negative number. This manner of controlling power to a device enables wide ranges of power control while generating acceptable levels of power line harmonics and while conforming to existing international regulations governing voltage variations.

Power control using at least 540 degrees of phase

A segment and heater fuser roll is disposed for a printing device including a plurality of heating elements in a preselected order relative to a voltage return. A plurality of voltage taps are disposed for applying selected power to ones of the plurality of heater elements. The heater elements vary in power density per unit length.

A roll useful in fusing marking material to a print sheet includes a coating disposed on at least a portion of the inner surface thereof. A lamp disposed inside the roll supplies radiant energy to the inner surface. The coating changes its absorptivity (such as color) as desired, to obtain specific desired temperatures at different portions of the roll. The coating can be thermochromic, changing its absorptivity in response to local temperature; or electrochromic, changing its absorptivity in response to an external electrical stimulus.

An apparatus for fusing print sheets, such as in xerographic printing, comprises a heating element, and a temperature-sensitive mounting for the heating element. The mounting changes a position of the heating element over the course of use of the apparatus, thereby enabling a more efficient use of the heating element and emitted heat within the fusing apparatus.
