    摘要： A method and system that enhances a user's experience when using a near eye display device, such as a see-through display device or a head mounted display device is provided. An optimized image for display relative to the a field of view of a user in a scene is created. The user's head and eye position and movement are tracked to determine a focal region for the user. A portion of the optimized image is coupled to the user's focal region in the current position of the eyes, a next position of the head and eyes predicted, and a portion of the optimized image coupled to the user's focal region in the next position.

    摘要： Embodiments relate to scanning a plurality of light beams across a corresponding plurality of zones in a field of view and collecting scattered light to enable an image of the field of view to be formed that spans the plurality of zones. According to an embodiment, a scanning endoscope tip may include structures configured to launch the plurality of scanned beams toward respective zones and receive separate light scattered from the respective beams impinging upon the respective zones. According to an embodiment, an image processor is operable to receive detection signals from corresponding light detectors and reconstruct an image of the field of view spanning the plurality of zones.

    摘要： A MEMS oscillator, such as a MEMS scanner, has an improved and simplified drive scheme and structure. Drive impulses may be transmitted to an oscillating mass via torque through the support arms. For multi-axis oscillators drive signals for two or more axes may be superimposed by a driver circuit and transmitted to the MEMS oscillator. The oscillator responds in each axis according to its resonance frequency in that axis. The oscillator may be driven resonantly in some or all axes. Improved load distribution results in reduced deformation. A simplified structure offers multi-axis oscillation using a single moving body. Another structure directly drives a plurality of moving bodies. Another structure eliminates actuators from one or more moving bodies, those bodies being driven by their support arms.

    摘要： A device for image transmission includes a first scanner at a first location and a second scanner at a second location, with an optical fiber linking the scanners. The first scanner scans the first location and couples light from the first location to the optical fiber. The fiber transmits the light to the second location where the second scanner constructs an image of the second location from the light. The two scanners are synchronized so that the constructed image corresponds directly to the scanned scene. The second scanner may be part of a retinal scanner, so that the image is formed directly on the user's retina. In another embodiment, the each of the scanners acts as a transceiver so that imaging is bi-directional.

    摘要： A display apparatus includes a scanning assembly that scans about two or more axes, typically in a raster pattern. A plurality of light sources emit light from spaced apart locations toward the scanning assembly such that the scanning assembly simultaneously scans more than one of the beams. The light sources are positioned such that their beams each illuminate discrete regions of the image field that are substantially non-overlapping with respect to the other discrete regions. The image is thus formed from a set of “tiles”. By activating a first light source during a forward sweep of the mirror and activating a second light source during a reverse sweep of the mirror, two halves a common line can be written during a single sweep of the mirror. Shifting the position of the sources such that the two halves are aligned reduces raster pinch. In alternative embodiments, the same approach is used for imaging. Also, various approaches to controlling the frequency responses of the various scanners are described, including active control of MEMs scanners and passive frequency tuning.

    摘要： A display apparatus includes an image source, an eye position detector, and a combiner, that are aligned to a user's eye. The eye position detector monitors light reflected from the user's eye to identify the pupil position. If light from the image source becomes misaligned with respect to the pupil, a physical positioning mechanism adjusts the relative positions of the image source and the beam combiner so that light from the image source is translated relative to the pupil, thereby realigning the display to the pupil. In one embodiment, the positioner is a piezoelectric positioner and in other embodiments, the positioner is a servomechanism or a shape memory alloy.

    摘要： Embodiments described herein include a turkey gobbler vocalization detection apparatus that is designed to collect, analyze, and store a turkey gobble vocalization over a period of time. The apparatus contains a parabolic collector, microphone, amplifier, analog-to-digital converter, audio digital signal processor, internal light, and a display unit within a housing element which is configured to be deployed in one of a plurality of wildlife environments. If a vocalization is detected, it is received, filtered, and analyzed using a Fourier analysis. If a detected spectra signature is within a range of a pre-programmed spectral signature signal of a turkey gobble, then the detected spectra signature, and at least the time and recording of the detected spectra signature are stored within an on-board memory module. Simultaneously, an output signal is sent to an internal light source to notify a user that a detected spectra signature is stored within the on-board memory module, and allow the user to access a 1-15 second incremental recording of the detected spectra signature using a five push-button display unit while a notification is transmitted over a wireless network.

    摘要： Technology is disclosed for enhancing the experience of a user wearing a see-through, near eye mixed reality display device. Based on an arrangement of gaze detection elements on each display optical system for each eye of the display device, a respective gaze vector is determined and a current user focal region is determined based on the gaze vectors. Virtual objects are displayed at their respective focal regions in a user field of view for a natural sight view. Additionally, one or more objects of interest to a user may be identified. The identification may be based on a user intent to interact with the object. For example, the intent may be determined based on a gaze duration. Augmented content may be projected over or next to an object, real or virtual. Additionally, a real or virtual object intended for interaction may be zoomed in or out.
