20120068913OPACITY FILTER FOR SEE-THROUGH HEAD MOUNTED DISPLAY - An optical see-through head-mounted display device includes a see-through lens which combines an augmented reality image with light from a real-world scene, while an opacity filter is used to selectively block portions of the real-world scene so that the augmented reality image appears more distinctly. The opacity filter can be a see-through LCD panel, for instance, where each pixel of the LCD panel can be selectively controlled to be transmissive or opaque, based on a size, shape and position of the augmented reality image. Eye tracking can be used to adjust the position of the augmented reality image and the opaque pixels. Peripheral regions of the opacity filter, which are not behind the augmented reality image, can be activated to provide a peripheral cue or a representation of the augmented reality image. In another aspect, opaque pixels are provided at a time when an augmented reality image is not present.03-22-2012

20100120334AUTOMATED CHEMICAL POLISHING SYSTEM ADAPTED FOR SOFT SEMICONDUCTOR MATERIALS - At least one wafer is suspended on a respective jig shaft above a polishing platen. The degree of parallelism between the wafer and the polishing platen is controlled using a three-point suspension, which allows for planar pitch adjustments using vertical actuation algorithms. As the wafer is lowered into contact against the polishing platen, a load cell senses how much of the weight of the jig shaft, wafer mount and wafer continues to be supported by the jig. The vertical displacement of the wafer is controlled using a linear actuator responsive to a signal from the load cell. Vertical actuation of the wafer serves to increase or decrease this amount of supported weight, in turn decreasing or increasing the amount of applied down-force exerted between the wafer and the platen. A compression spring is used to increase the resolution of the pressure control. Finally, system components exposed to the work environment are encapsulated by chemically resistive components to prevent corrosion of system components.05-13-2010

20130050642ALIGNING INTER-PUPILLARY DISTANCE IN A NEAR-EYE DISPLAY SYSTEM - The technology provides for automatic alignment of a see-through near-eye, mixed reality device with an inter-pupillary distance (IPD). A determination is made as to whether a see-through, near-eye, mixed reality display device is aligned with an IPD of a user. If the display device is not aligned with the IPD, the display device is automatically adjusted. In some examples, the alignment determination is based on determinations of whether an optical axis of each display optical system positioned to be seen through by a respective eye is aligned with a pupil of the respective eye in accordance with an alignment criteria. The pupil alignment may be determined based on an arrangement of gaze detection elements for each display optical system including at least one sensor for capturing data of the respective eye and the captured data. The captured data may be image data, image and glint data, and glint data only.02-28-2013
20130050833ADJUSTMENT OF A MIXED REALITY DISPLAY FOR INTER-PUPILLARY DISTANCE ALIGNMENT - The technology provides for adjusting a see-through, near-eye, mixed reality display device for alignment with an inter-pupillary distance (IPD) of a user by different examples of display adjustment mechanisms. The see-through, near-eye, mixed reality system includes for each eye a display optical system having an optical axis. Each display optical system is positioned to be seen through by a respective eye, and is supported on a respective movable support structure. A display adjustment mechanism attached to the display device also connects with each movable support structure for moving the structure. A determination is automatically made as to whether the display device is aligned with an IPD of a user. If not aligned, one or more adjustment values for a position of at least one of the display optical systems is automatically determined. The display adjustment mechanism moves the at least one display optical system in accordance with the adjustment values.02-28-2013
20130114043SEE-THROUGH DISPLAY BRIGHTNESS CONTROL - The technology provides various embodiments for controlling brightness of a see-through, near-eye mixed display device based on light intensity of what the user is gazing at. The opacity of the display can be altered, such that external light is reduced if the wearer is looking at a bright object. The wearer's pupil size may be determined and used to adjust the brightness used to display images, as well as the opacity of the display. A suitable balance between opacity and brightness used to display images may be determined that allows real and virtual objects to be seen clearly, while not causing damage or discomfort to the wearer's eyes.05-09-2013
20130286178GAZE DETECTION IN A SEE-THROUGH, NEAR-EYE, MIXED REALITY DISPLAY - The technology provides various embodiments for gaze determination within a see-through, near-eye, mixed reality display device. In some embodiments, the boundaries of a gaze detection coordinate system can be determined from a spatial relationship between a user eye and gaze detection elements such as illuminators and at least one light sensor positioned on a support structure such as an eyeglasses frame. The gaze detection coordinate system allows for determination of a gaze vector from each eye based on data representing glints on the user eye, or a combination of image and glint data. A point of gaze may be determined in a three-dimensional user field of view including real and virtual objects. The spatial relationship between the gaze detection elements and the eye may be checked and may trigger a re-calibration of training data sets if the boundaries of the gaze detection coordinate system have changed.10-31-2013
