  • Patent number: 10830988
    Abstract: The subject of this invention is a laterally unconstrained magnetic joint and application of said joint in tip-tilt and piston-tip-tilt optical mounts. The laterally unconstrained magnetic joint in its basic embodiment comprises two interfacing parts: one having a flat surface interfacing a convex surface of the other, wherein one or both parts are made from permanent magnets that are magnetized along the axis of the joint, and the other of the said parts is made from a ferromagnetic material thus creating magnetic force attraction between the two parts. The resulting lack of lateral mechanical constraint between the two parts of the joint is utilized in tip-tilt mounts by decoupling an adjustor and/or actuator from the payload resulting in a simple, uniform design, while magnetic force provides retention sufficient for a wide variety of applications.

  • Patent number: 10809537
    Abstract: A waveguide display is used for presenting media to a user. The waveguide display, includes a light source, a projection assembly (PA), a source waveguide (SW), and an output waveguide (OW). The light source emits light, the PA reshapes the wavefront of the light and the SW receives the light from the PA, expands the light in a first dimension and outputs the expanded light. The SW has an adjustable curvature along the first dimension expanding the light with a curved wavefront. The OW receives the expanded light emitted from the SW, expands the expanded light in a second dimension orthogonal to the first dimension to form image light and outputs the image light. The wavefront curvature from the light source, the curvature of the OW along the second dimension and the curvature of the SW control a location of an image plane of the image light.

  • Patent number: 10795151
    Abstract: An encoder of a terahertz (THz)-based absolute positioning system used for decoding patterns from THz-band measurements. The encoder includes a scale with a multi-layer reflective/transmissive structure having a matrix with rows. Each row of the matrix corresponds to a plurality of patterns, such that each pattern is used to form a measurement. An emitter emits a THz waveform to the scale. A receiver is used to measure amplitudes of the THz waveform reflected from the scale. A memory stores data including predetermined positions of the emitter based on the patterns of the layers from the scale. Wherein one or more processors can determine a position of the emitter from the measurements of the amplitudes received by the receiver, based on the stored data. An output interface can be used to render the position of the emitter.
