摘要:
Methods of making a microelectromechanical system (MEMS) device are described. In some embodiments, the method includes forming a sacrificial layer over a substrate, treating at least a portion of the sacrificial layer to form a treated sacrificial portion, forming an overlying layer over at least a part of the treated sacrificial portion, and at least partially removing the treated sacrificial portion to form a cavity situated between the substrate and the overlying layer, the overlying layer being exposed to the cavity.

A MEMS comprising a sacrificial structure, which comprises a faster etching portion and a slower etching portion, exhibits reduced damage to structural features when in forming a cavity in the MEMS by etching away the sacrificial structure. The differential etching rates mechanically decouple structural layers, thereby reducing stresses in the device during the etching process. Methods and systems are also provided.

A thin black mask is created using a single mask process. A dielectric layer is deposited over a substrate. An absorber layer is deposited over the dielectric layer and a reflector layer is deposited over the absorber layer. The absorber layer and the reflector layer are patterned using a single mask process.

Methods of making MEMS devices including interferometric modulators involve depositing various layers, including stationary layers, movable layers and sacrificial layers, on a substrate. Voids are formed in one or more of the various layers so as to form a non-planar surface on the movable and/or the stationary layers. The voids are formed to extend through less than the entire thickness of the layer where they are being formed. Other layers may be formed over the formed voids. Removal of the sacrificial layer from between the resulting non-planar movable and/or stationary layers results in a released MEMS device having reduced contact area between the movable and stationary layers when the MEMS device is actuated. The reduced contact area results in lower adhesion forces and reduced stiction during actuation of the MEMS device. These methods may be used to manufacture released and unreleased interferometric modulators.

Systems and methods consistent with disclosed embodiments provide for a method for redacting documents comprising associating at least one redaction template with a document, wherein the redaction template includes information identifying at least one section of a document to be redacted. The document can be printed using the redaction template, wherein information in the redaction template is used to redact sections of the document prior to printing the document on a print medium. In some embodiments, the redaction template, and the document associated with the redaction template may be separate files. The method can be invoked using document processing software, and/or a printer driver, and user interfaces associated with document processing software may be used to create the redaction template, which can be stored as a document layer. Redactions stored in the template may also be associated with a security level.

An anti-collision emergency braking system enables emergency information transferring from leading vehicle to trailing vehicle and enables emergency automatic braking. It comprises a central commanding element which takes input from a number of sensing elements and gives commands to other acting elements: a receiver which receives emergency signals from the leading vehicle, a transmitter which sends out emergency signals toward the trailing vehicle, an accelerometer which senses the acceleration extents of the present vehicle, an automatic braking element which applies certain amount of braking power after receiving the commands from the central commanding element, and one or more warning elements.
摘要:
A printing method that allows a user to initiate printing of files on a host computer from the printer side with one or more button touches. The user initiates printing from the printer using one or more buttons, such as a dedicated easy print button. The printer sends a data request to the host computer. A printer monitoring program on the host computer receives and responds to printer requests. Upon receiving the data request from the printer, the host computer finds the most active application window (the window on top of all other windows), calls the application's default printing setting, generates a printing task for the most active opened file, and sends it to the printer. The printer prints the file received from the host computer. Other printing modes are also possible, such as printing all opened files in the most active application, etc.

An interferometric spatial light modulator comprises of two cavities. One is the optical resonant cavity having a partially reflective film and a movable reflective membrane as two walls, and the other is the electromechanical actuation cavity having the movable reflective membrane and a bottom metal layer as electrodes. The spatial light modulator is built on silicon substrate and is actively addressed. A microdisplay apparatus of such spatial light modulators and a projection display system using such microdisplay are also disclosed.
