A protective device for attaching to and protecting at least one article includes a cover having an attachment surface and a display surface opposing the attachment surface. An adhesive coating is applied to the attachment surface of the cover to facilitate adhesion of the cover to an article. A removable backing is releasably attached to the adhesive coating and at least one relief notch is formed in the cover through the attachment surface of the cover and terminates beneath the display surface of the cover.

A fluid ejection and scanning assembly includes a drop ejection element that causes fluid to be ejected from an associated nozzle chamber when activated. A first photosensor is coupled to the ejection element and is configured to cause the ejection element to be activated when the photosensor is illuminated by a light source. A second photosensor captures image data based on light reflected from media.

摘要:
A light-filtering element for a display device is provided. The element includes at least one filter having a chamber with a filtering fluid, the filtering fluid selectively disposed in an optical path, and a liquid motion actuator selectively configured to move the filtering fluid substantially into and out of the optical path.

A fluid ejection and scanning system includes a fluid ejection assembly. The assembly includes a first plurality of photosensors, and a first plurality of ejection elements. Each of the ejection elements is configured to cause fluid to be ejected when the ejection element is activated. Each one of the photosensors in the first plurality is coupled to a respective one of the ejection elements for activating the ejection element. A second plurality of photosensors captures image data to generate a digital image of a media. A first light source of the system emits a light beam. A control system scans the light beam across the printhead assembly and selectively illuminates the photosensors in the first plurality, thereby activating the ejection elements coupled to the illuminated photosensors.

A display system is provided, the system including an illumination source configured to produce light and direct light along an optical path, a plurality of color filters disposed in the optical path configured to generate a plurality of colored light beams, and a spatial light modulator disposed in the optical path adapted to receive and adjust the colored light beams to produce an image.
摘要:
A mixing apparatus having a channel for guiding an input gas stream, a drop on demand fluid drop emitting apparatus for emitting drops of a fluid into the input gas stream to produce a gas mixture that contains the fluids drops, and a pressure control system for controlling a pressure of the fluid in the drop on demand fluid drop emitting apparatus.
摘要:
A fluid ejector head, including a fluid ejector disposed on an ejector support, and a semiconductive junction photo sensor electrically coupled to the fluid ejector. The fluid ejector head also includes a photon source photonically coupled only to the semiconductive junction photo sensor. Photons emitted from the photon source interact with the semiconductive junction photo sensor and generate an activation signal. The activation signal in turn activates the fluid ejector ejecting a fluid away from the fluid ejector.
