Abstract: A spacer device includes an elongate spacing member extending a longitudinal axis for securing to electrical transmission lines, and has a minimum thickness dm. At least one thickened portion having a thickness Tt and length dt is positioned intermediate along the spacing member to form at least two column lengths Lc separated by the at least one thickened portion. Each column length Lc has a portion with the minimum thickness dm. The thickness Tt and length dt of the at least one thickened portion can be at least two times the minimum thickness dm to form at least one end support for the at least two column lengths Lc, such the at least two column lengths Lc behave as separate Euler type columns for producing increased Euler buckling strength with a minimal increase in weight.

The invention enables real-time controlling of the image quality and the image frame rate by means of a foot-switcher with the new function of being driven by a pressure-sensitive controller.

Abstract: A light-weight and ultrathin waveguide optical element having a large field of view includes two or more layers of waveguide plates provided to be overlapped with each other. Within each layer of the waveguide plate are included multiple reflective surfaces with different reflectivity, such that light transmitted through the waveguide plate has a substantially uniform distribution of intensity in a predetermined area when exiting from the waveguide plate. The waveguide optical element is ultrathin such that it can be directly mounted into a spectacle frame. Use of the waveguide optical element with a projection optical assembly can improve user experience as well as display effect with good contrast.

Abstract: A wearable augmented reality (AR) or virtual reality (VR) display apparatus includes an optical waveguide; an optical free-form surface; and a microdisplay; wherein optical free-form surface is optically coupled to the waveguide through an inclined optical path. A near-eye display apparatus includes two or more layers of waveguide plates arranged to overlap with each other, wherein within each layer of the waveguide plate includes multiple reflective surfaces different in reflectivity, so as to ensure that light transmitted through the waveguide plate has a substantially uniform distribution of intensity in a predetermined area when exiting outward from the waveguide plate. The waveguide optical element is ultrathin so as to be directly mounted into a spectacle frame. User experience and contrast level are also improved.

Abstract: An apparatus for viewing augmented reality images in a hands-free manner includes a tracker base in which various interchangeable trackers may be placed. The interchangeable trackers include an image specialized to an application framework running on a device with an image capture device in range of the image. An arm connects to and extends from the tracker base, and includes a clasp for holding the device. With the augmented reality application running, the device provides a display of the augmented reality images associated with the image on the interchangeable tracker in a hands-free manner. The tracker base spins, providing different viewpoints of the augmented reality images. The tracking element and the image capture device are held in a fixed spatial relationship with respect to one another, resulting in a stable image. The apparatus provides interactions in a multi-system environment by invoking commands between the device and an external multimedia component.
