Abstract: A 3D image pixel in a spatially multiplexed stereo 3D display includes a first left-eye subpixel and a second left-eye subpixel that are both driven when displaying the left-eye image. The 3D image pixel also includes a first right-eye subpixel and a second right-eye subpixel that are both driven when displaying the right-eye image. The subpixels may all have a square shape. Single color emitters in the subpixels of the same eye may be driven by the same electronics. A 3D image pixel in a second spatially multiplexed stereo 3D display includes a left-eye pixel driven when displaying the left-eye image and a right-eye pixel driven when displaying the right-eye image. The pixels may all have a rectangular shape, and the horizontal measurement of the pixels may be greater than the vertical measurement of the pixels.

Abstract: A method of mounting screen material may include a screen mounted to a frame at multiple mounting points. One embodiment may include mounting patches attached along the perimeter of the screen. These mounting patches may be strain relieved in order to enable rolling the screen without sacrificing the in-plane rigidity of the patches when the screen is mounted to a frame. Stated differently, the strain relieved patches may reduce the strain on the screen in the circumstance the screen is rolled onto a core. The mounting patches may be strain relieved by locating notches or slits in the mounting patch.

Abstract: An insertion mechanism for a wearable drug delivery device includes a needle hub, a needle coupled to the needle hub, a flexible boot removably coupled to the needle hub, and a cannula coupled to the flexible boot. The needle hub, the needle, the flexible boot, and the cannula are movable between a first position and a second position. Upon moving the needle hub, the needle, the flexible boot, and the cannula from the first position to the second position, the cannula engages a floor member to restrict movement of the cannula and the flexible movement towards the first position.

Abstract: An aspect of the present invention provides a circuit and arrangement for generating and amplifying an electric scalar potential field and a method for capturing the associated available electromagnetic energy into the system. The device is comprised of a transformer whose primary is powered periodically by short pulse durations; a resonant coupled transformer secondary circuit with synchronous parameter variation; and an extraction circuit of appropriate impedance and components to provide isolation and distribution to load.

Abstract: A polyphosphate-based glass scale inhibition composition comprising from about 45 to about 55 mole percent P2O5, from about 35 to about 45 mole percent of an oxide of an alkaline earth metal, and from about 8 to about 12 mole percent of an oxide of an alkali metal.

Abstract: Liquid crystal devices are described that maintain performance of polarization/amplitude modulation under high irradiance conditions. Configurations that isolate polarizing elements under high thermal load are discussed which allow other elements, such as glass, which may be sensitive to stress birefringence to remain near optimum thermal conditions.

Abstract: A stiffening strip at selected edges of a screen may enable the use and mounting of a high-elastic modulus substrate screen material. Such screen materials may be engineered to provide polarization-preserving characteristics, and be applied to or part of the high-elastic modulus substrate. Furthermore, the stiffening strip may enable the use of screen vibration techniques to reduce speckle in display applications that use projection screens, particularly those display applications using illumination sources prone to speckle such as laser-based projection. The screen vibration may be provided by a vibrating device attached to the stiffening strip.

Abstract: A fluid delivery system for a dental cleaning appliance includes a nozzle for delivering a burst of working fluid to the teeth of a user, and a fluid conduit for conveying working fluid to the nozzle. A body of the nozzle defines a fluid chamber and a channel for conveying working fluid from the fluid chamber to a fluid outlet from the nozzle. The fluid chamber has a tangential inlet for receiving working fluid from the fluid conduit.

Abstract: A dental cleaning appliance includes a nozzle having a fluid chamber, a fluid outlet and a channel extending between the fluid chamber and the fluid outlet. A water reservoir provides water to a pump for generating a burst of pressurized water, which is supplied to the nozzle by a fluid conduit. Following the delivery of the burst of water to the teeth of the user, a valve draws water back into the fluid chamber from the channel to prevent that water from dripping from the fluid outlet before the next water burst is generated by the pump. Simultaneously, air may be drawn into the fluid chamber, for example, through the fluid outlet, for mixing with the next water burst to generate a fluid burst for delivery to the user's teeth.

Abstract: Disclosed is an apparatus and method of tiling and stitching together multi-projector images. The projection system enhances brightness, enables polarization based stereoscopic imagery and matches brightness for all viewers that view the images from the projection system. The projection system includes two or more projectors and projects two dimension and three dimensional images onto projection screens, such as gain screens.

Abstract: A projection system includes first and second illumination sources and a homogenizer component. The first illumination source has a first numerical aperture value. The second illumination source has a second numerical aperture value lower than the first numerical aperture value. The homogenizer component on the illumination path is configured to receive light from both the first and second illumination sources. A projection lens in the imagining path is configured to receive an image data stream that includes a sequence of image frames having an image frame period. The first and second illumination sources are configured for modulation at a rate equivalent to the image frame period. One or more active irises may perform the modulation.

Abstract: A desktop application and supporting web site for capturing audio and video recordings or other digital content of differing modalities is introduced, wherein multiple participants in a collaborative session may be in separate remote locations. The application includes providing a high quality data format for transferring recordings, audiovisual data and the like to a remote network location or computer and a real-time data format for intercommunicating comments and instructions that are not recorded. Peer-to-peer and server-client implementations may be optimized regarding delivery time (latency) versus content quality. The desktop application also provides mechanisms for playing back sound, video or other data for participants' reference, along with synchronized presentations of textual, audio and visual material corresponding to the session.

Abstract: The present disclosure describes a manufacturing method for seaming materials. The process may be suitable for manufacturing high performance projection screens using a number of methods including, but not limited to, conventional (convert-before-coating) methods, or convert-after-coating methods. An objective of the present disclosure is to identify a process which may substantially minimize distortion of the local surface normal in the vicinity of the join.
