A plurality of substantially simultaneous inputs are associated with one or more applications, wherein it is determined if the plurality of inputs includes unacceptable inputs and wherein unacceptable inputs are ignored.

Input association

Embodiments of reflecting light off surfaces are disclosed.

Reflecting light

In accordance with one embodiment of the present disclosure, a difference is detected between a first image and a second image. The second image can include at least a portion of the first image reflected from a display panel and light from an object passing through the display panel.

Display panel

A display system includes a display, and a projection device configured to project, substantially simultaneously, image pixels onto the display and an optical signal encoding data onto the display.

Display system

A system including a projection screen having a surface, a projector configured to project images onto the surface of the projection screen and a camera configured to capture one or more images of the surface of the projection screen. An object can be configured to rest upon the surface, wherein the object and at least one of the projector and the camera are configured to cooperate with one another to communicate audio data through the surface of the projection screen while the object is resting upon the surface.

Communicating audio data

A method and apparatus senses light reflected off of a surface of an object at angles with respect to incident light.

Sensing light

A rejuvenation station has a housing with a first area adapted to hold a fluid supply, and a second area adapted to hold a printer cartridge. In the first area is a first fluidic interconnect that is adapted to couple with the fluid supply. In the second area is a second fluidic interconnect that is adapted to couple with the printer cartridge. A fluid path in the housing couples the fluidic interconnects. An actuator extracts fluid from at least one of the fluid supply and the printer cartridge, and inserts fluid into the printer cartridge through the fluid path.

Rejuvenation station and printer cartridge therefore

A marking fluid valve for a marking fluid delivery system of a media marking device. The marking fluid valve includes a resilient body having first and second opposite ends in fluid communication with one another, with the first end having a pair of opposed lips. The pair of opposed lips define a normally closed slit extending therebetween. Compressing the first end of the resilient body along axes of the lips deforms the resilient body from a closed position, in which the lips are in contact with one another to close the slit and prevent marking fluid from passing through the slit, to an open position, in which the lips are spread at least partially apart from one another to enable marking fluid to pass through the slit.
