A method of generating a representation of a structure includes providing an ad hoc mesh network having at least two nodes associated with the structure, obtaining time of flight data for each node in the network, and using the time of flight data to generate the representation of the structure. A method of generating a three-dimensional representation of a structure includes providing an ad hoc mesh network having at least three nodes associated with the structure, wherein at least one node is a mobile node that moves around the structure, obtaining time of flight data for each pair of nodes in the network, and using the time of flight data to generate the three-dimensional representation of the structure.

A method of building a room list in a structure having at least two rooms includes forming a mesh network in the structure with at least two nodes, each node having a room-limited communication module, analyzing signals from the room-limited communication modules between nodes, segmenting the nodes into rooms based upon the signals, and associating each node of the plurality of nodes with one of the rooms. A method of making a room list includes providing at least two nodes, measuring signals between nodes, analyzing the signals, and associating a grouping of nodes to a room based on the analyzing.

A method and system for masking a surface to be etched is described. A droplet source ejects droplets of a masking material for deposit on a thin-film or other substrate surface to be etched. The temperature of the thin-film or substrate surface is controlled such that the droplets rapidly freeze upon contact with the thin-film or substrate surface. The thin-film or substrate is then etched. After etching the masking material is removed.

A method for treating a substrate is disclosed in which a propellant stream is passed through a channel and directed toward a substrate. Substrate pre-marking or post-marking treatment material is controllably introduced into the propellant stream and imparted with sufficient kinetic energy thereby to be made incident upon a substrate. A multiplicity of channels for directing the propellant and treatment material allow for high throughput, high resolution in-situ treatment. Marking materials and treatment materials may be introduced into the channel and mixed therein prior to being made incident on the substrate, or mixed or superimposed on the substrate without registration. One example is a single-pass, full-color printer.

A pixelized scintillation layer is taught in which high aspect ratio columns of scintillation material are formed. The columns may be sized and spaced to correspond to the sizing and spacing of an underlying sensor array, or they may be sized such that there is plurality of columns for each pixel. A method for forming the pixelized scintillation layer includes the step of forming openings such as wells, vias, or channels in a body, for example by etching a thick photoresist, ion beam etching, anodic etching, etc., and the step of filling the openings with scintillation material. A completed image sensing apparatus is also taught.

A micro-machined movable light emitting assembly is formed on or from an undoped or pure III-V substrate or formed on or from a doped III-V substrate. The movable light emitting assemblies are to be actuated using force generators, to generate the various mechanical degrees of freedom depending on the type of stage suspension and actuation.

A full-color, tunable organic light emitting diode (RCOLED) includes a high-reflection tunable membrane and a high-reflection dielectric mirror that form a resonant cavity. A white light OLED is located in the resonant cavity. The high-reflection tunable membrane is moved to alter the resonant cavity length, and/or tilted/bowed to change the finesse of the resonant cavity. In this way, color, brightness and color saturation of the emitted light from the RCOLED can be tuned. The RCOLED may also include a microlens structure to improve off-axis viewing.

A bistable valve useful for paper handling applications is disclosed. The valve can be batch fabricated in two dimensional valve arrays, with each valve in the array being controlled by passive matrix addressing. Typically, each valve includes a valve housing having an aperture plate defining an aperture therethrough, and an opposing plate positioned in spaced apart relationship to the aperture plate. A flexible film or strip is attached at its first end to the aperture plate and at its second end to the opposing plate. Valve action is provided by use of at least two switching electrodes for moving the flexible film between an aperture blocking position and an aperture open position, with at least one of the switching electrodes positioned adjacent to the aperture plate and at least one of the switching electrodes positioned adjacent to the opposing plate. To reduce unswitched movement when the switching electrode bias is reduced or not present, at least two electrostatic or mechanical catches are used.

A modulator for modulating incident rays of light, the modulator comprising a plurality of equally spaced apart beam elements, each of which includes a light reflective planar surface. The elements are arranged parallel to each other with their light reflective surfaces parallel to each other. The modulator includes means for supporting the beam elements in relation to one another and means for moving the beam elements relative to one another so that the beams move between a first configuration wherein the modulator acts to reflect the incident rays of light as a plane mirror, and a second configuration wherein the modulator diffracts the incident rays of light as they are reflected therefrom. At least one of the facing surfaces of the beam elements and underlying substrate is configured to reduce any tendency to stick as they are pulled together. In operation, the light reflective surfaces of the beam elements remain parallel to each other in both the first and the second configurations and the perpendicular spacing between the reflective surfaces of adjacent beam elements is equal to m/4 times the wavelength of the incident rays of light, wherein m=an even whole number or zero when the beam elements are in the first configuration and m=an odd number when the beam elements are in the second configuration.

An embodiment is a method and apparatus for ultrasonic contact imaging. A thin-film transistor (TFT) array is deposited on a substrate. A receiver having a plurality of receiver elements is deposited on the TFT array to receive a received signal. A transmitter adjacent to the receiver generates a transmit signal at an ultrasonic frequency. The transmit signal is reflected from a surface to produce a reflected signal. The received signal is a superposition of the transmit signal and the reflected signal as result of interference. The received signal is representative of differences in acoustic impedances across the surface.
