Abstract: An integrated circuit having at least one micromechanical element thereon is described comprising a support substrate, a sensor element electrically connected to a logic circuit, and the logic circuit electrically connected to a semiconductor visual display element. The integrated circuit may be manufactured by a process which comprises providing a support substrate, forming at least two elements selected from a first group consisting of a micromechanical sensor element, a logic circuit and a semiconductor visual display element on said support, and manufacturing at third element on said support substrate, said third element selected from a second group consisting of a micromechanical sensor element, logic circuit and a semiconductor display element, which was not selected from the first group. In one embodiment of the process of manufacture, all three of at least three elements are constructed on the support itself, preferably by a microlithographic process.

Abstract: A nasal cannula for delivering air to a patient's nares. Two delivery tubes are provided to supply air to a pair of nasal inserts each of which conform to the shape of the nare. Properly placed bleed ports reduce noise and reduce carbon dioxide retained in the system. The cannula is positioned on the face with the aid of a strap system.

Abstract: 1+1 Mesh Protection provides 1+1 protection for connections across an automatically routed mesh network, where a connection is setup automatically by using an intelligent signaling and routing protocol. 1+1 Mesh Protection can set up, tear down, and reroute both the working path and protect path across the mesh network automatically based on a specified service profile. 1+1 Mesh Protection interoperates seamlessly with traditional 1+1 protection mechanisms such as APS 1+1 protection in SONET networks.

Abstract: A MEMS based thermoacoustic cryo-cooler for thermal management of cryogenic electronic devices. The cryogenic cooling system can be integrated directly into a cryogenic electronic device. A vertical comb-drive provides an acoustic source through a driving plate to a resonant tube. By exciting a standing wave within the resonant tube, a temperature difference develops across a stack in the tube, thereby enabling heat exchange between heat exchangers. A tapered resonant tube improves the efficiency of the cooling system, compared with a simple cylinder configuration, leading to reduced harmonics and strong standing waves.

Abstract: An optical device is formed of an array of micro-wedges where each micro-wedge is different in size and shape from adjacent micro-wedges. Each micro-wedge of the array directs light in a predetermined direction toward a particular sub-region of an angular pattern. The positions of the micro-wedges in the device may be essentially random with respect to the corresponding positions of the sub-regions. The device causes the output light to fill a large angular spread with homogenized light with clear boundaries and edges. The device employs refraction or reflection, and the device operates efficiently over a broad wavelength band.

Abstract: When a user wants to display application program status information or invoke a help function (either manually or automatically), a context-sensitive status or help display is provided that is either physically or virtually separate from the application program display. That is, the status or help display does not conceal or otherwise interfere with the main output of the application program. With this arrangement, the user is not inconvenienced by invoking a status request or help functions, nor is the user distracted by its display. The status or help information may be displayed in a portion of a single screen that does not overlap with the active window of the application program (a virtually separate display). Alternatively, a physically separate auxiliary display may be provided for display of the status or help information.

Abstract: A ventilation or CPAP interface system adapted to be inserted into a nares of a user to secure the interface. A cannula adapted to be connected to a source of ventilation gas forms a first portion of an input gas flow passage to supply the ventilation gas to the user. A nasal insert adapted to be inserted the nares of the user forms a second portion of the input gas flow passage from the cannula to a distal end of the nasal insert. A seal portion adapted to engage a portion of the first naris is provided adjacent the distal end of the nasal insert. Ventilation interface system may optionally include feed tubes, y-connector, tube holder, headgear and a headgear flange.

Abstract: The ventilation interface for sleep apnea therapy interfaces a ventilation device to the patient's airways. The ventilation interface includes a pair of nasal inserts made from flexible, resilient silicone which are oval shaped in cross-section and slightly tapered from a base proximal the ventilation supply to the distal tip end. A bead flange is disposed about the exterior of each insert at the distal end of the insert. In one embodiment, a valve is disposed between the nasal inserts and a source of positive airway pressure, the valve having a rim with a one-way diaphragm pivotally attached to the valve body with an inflatable bladder depending from the rim which seals against an exit port during inspiration and deflates to uncover the exit port on expiration. Another embodiment has nasal inserts without positive airway pressure but with a removable filter in the inserts for filtering inspired air.

Abstract: A nasal ventilation interface comprising a hollow body having at least one and preferably two nasal apertures, and at least one and preferably two inhale apertures, and at least one and preferably two nasal insert tubes each associated with one of the nasal apertures and having an annular sleeve that forms a seal with a nostril of the patient. The hollow body has at least one and preferably two exhale apertures and at least one valve assembly associated with the exhale apertures that are capable of preventing air from passing through the exhale aperture upon the patient inhaling and allowing air to pass through the exhale aperture upon exhaling. The hollow body may also have at least one and preferably two filters for retaining heat and moisture from the exhale air and transferring the retained heat and moisture into the inhale air.

Abstract: A lenslet array having lenslets where the lenslets are variously shaped, and/or rotated and/or tilted, reducing gap images in an image formed by pixels/subpixels, where the pixel/subpixels have gaps between each other forming the gap images.

Abstract: A diffractive element used in conjunction with a grating to move a desired order beam off-axis, thereby reducing interference by undesired orders. Use of the off-axis grating allows a more uniform beam in the presence of manufacturing defects, such as etch depth errors. The diffractive element used with the off-axis grating may include a beam shaper, a one-dimensional beam splitter, or a two-dimensional beam splitter.

Abstract: A multi-aperture beam integrator system/method for producing an polygon or other complex optical pattern on an image plane, which can be continuously varied in size, aspect ratio, or shape, is described. The integrator/method uses optical array elements having various phase functions, which can be combined to create optical patterns. Varying the location of the optical array elements with respect to each other and/or moving individual unit cells contained within the optical array elements can create continuously varying optical patterns at a desired location.

Abstract: An antenna formation device/method has been developed to create variable shaped antennas using predetermined interference patterns to expose and develop a photoresist layer that is etched on a substrate to form the structure corresponding to the desired variable shaped antenna.

Abstract: A beam integrator system, which integrates multiple beams into fewer beams of increased intensity by using a combination of optical elements and lenses.

Abstract: A master wafer is replicated by creating a mold by plating a nickel electroform on a surface of a silicon wafer. Thereafter, a child wafer is prepared with a layer of photoresist or similar material that is compatible with plasma-etching techniques. Thereafter, the mold shape is transferred to the photoresist through compression molding, thereafter the child wafer is etched.
