Abstract: A computer system displays a first object that includes at least a first portion of the first object and a second portion of the first object and detects a first gaze input that meets first criteria, wherein the first criteria require that the first gaze input is directed to the first portion of the first object in order for the first criteria to be met. In response, the computer system displays a first control element that corresponds to a first operation associated with the first object, wherein the first control element was not displayed prior to detecting that the first gaze input met the first criteria, and detects a first user input directed to the first control element. In response to detecting the first user input directed to the first control element, the computer system performs the first operation with respect to the first object.

Abstract: A fluid delivery system includes a smart hose. The smart hose includes a fluid conduit configured to deliver a fluid. The smart hose further includes a first electrically conductive element configured to deliver electricity through a length of the smart hose. The fluid delivery system further includes master hub disposed on a fluid delivery device. The fluid delivery system also includes at least one slave hub disposed on the smart hose and communicatively coupled to the master hub.

Abstract: An ink replenishment system for supplying a working solution of an ink to an electrographic imaging device. A plurality of removable ink cartridges each have at least a first compartment containing ink concentrate and a second compartment. A fluid handling system couples the first compartment of each ink cartridge to a respective working solution reservoir. A controller controls the flow of ink concentrate from each ink cartridge and liquid carrier from a source of liquid carrier to maintain a working solution concentration of working solution in each of the working solution reservoirs. A return system fluidly couples each of the developer stations to the second compartment of the respective ink cartridges. Alternate embodiments include one compartment and three compartment cartridges, and locating the working solution reservoir in the removable cartridge.

Abstract: A system for substantially maintaining color density in liquid toners for electrographic printers is disclosed. The system includes means for substantially continuously supplying toner concentrate to a printer and means for substantially continuously withdrawing liquid toner from a printer into a waste flowstream. A method to achieve substantially consistent color density of liquid toner in an electrographic printing system is also disclosed.

Abstract: A receive magazine configured to be positioned in a generally upright, vertical orientation for passively collecting a plurality of flexible sheets of media. The top wall of the enclosure has a collection door in the top wall of a light-tight enclosure allows sheets of media to be passively received within the magazine. A contoured plate is hinged along a hinge line near the collection door on a non-stacked side of the enclosure. The plate is planar near the hinge line and is non-planar at an end of the plate opposite from the hinge line. A biasing mechanism is positioned near the collection door for resiliently biasing the plurality of flexible sheets of media laterally toward the non-stacking side of the enclosure biasing the plate away from the non-stacking side of the enclosure.
