  • Patent number: 10656511
    Abstract: A light pattern projector with a pattern mask to spatially modulate an intensity of a wideband illumination source, such as an LED, and a projector lens to reimage the spatially modulated emission onto regions of a scene that is to be captured with an image sensor. The projector lens may comprise a microlens array (MLA) including a first lenslet to reimage the spatially modulated emission onto a first portion of a scene, and a second lenslet to reimage the spatially modulated emission onto a first portion of a scene. The MLA may have a fly's eye architecture with convex curvature over a diameter of the projector lens in addition to the lenslet curvature. The pattern mask may be an amplitude mask comprising a mask pattern of high and low amplitude transmittance regions. In the alternative, the pattern mask may be a phase mask, such as a refractive or diffractive mask.

  • Patent number: 10017135
    Abstract: A branching structure for connecting a branch harness to a main line harness, includes connection terminals configured to electrically connect branch lines of the branch harness to main lines of the main line harness respectively, a terminal block on which the connection terminals are supported, and fasteners that respectively fasten the connection terminals onto the terminal block. Each of the connection terminals has a belt-shaped wound portion to be wound around a corresponding one of the main lines. The wound portion is fastened by a corresponding one of the fasteners so that both ends of the wound portion come closer to each other and a center portion of the wound portion tightens around the main line so as to be brought into surface contact with a bar conductor of the main line.

  • Publication number: 20170285774
    Abstract: An active stylus enables an electronic device to provide a user-friendly user input. The active stylus uses various sensors and feedback mechanisms to characterize or simulate the audible and haptic feedback associated with various writing instruments. The sensors capture pressure, speed, vibration, sound, and other characteristics of using a specific writing instrument on a given surface. This enables the active stylus to simulate the writing instrument accurately while avoiding increased haze and optical distortions due to etching or engineered film.

  • Patent number: 9553352
    Abstract: A display, such as for a touch-sensitive communication device, can include a transparent cover glass, pixels that emit light through the cover glass, and multiple antennas positioned along respective paths in an inactive area between the pixels. The antennas do not obstruct the light produced by the pixels, and can therefore be composed of opaque materials, such as metallic thin films, without affecting the optical properties of the display. In some examples, several antennas can have the same size and shape but different orientations, so that a radio can switch between or among the antennas to optimize reception. In some examples, the antennas can have different sizes and/or shapes, so that the antennas can send and/or receive radio signals in different frequency ranges of the electromagnetic spectrum. In some examples, locating the antennas in the display can allow the device to include a metallic housing.
