Abstract: A head-mounted display (HMD) device (100) includes one or more active shutters (128, 130), a first photodiode (132, 502, 504, 506, 612) configured to detect a synchronization signal, and a controller (412, 508) configured to control the one or more active shutters based on the synchronization signal. The one or more active shutters are configured to alternate between an open state to pass light and a closed state to block light for reducing a duty cycle of a display screen (122, 406, 506, 604) of a mobile device (120) positioned within the HMD device. The synchronization signal provides a timing to block light from the display screen for a display update duration corresponding to a subset of pixels of the display screen.

Title: Augmented reality spatial guidance and procedure control system
Inventor: MARCHAND STACEY LEIGHTON
IPC: G09G5/00
Filed: 2019-04-17
Abstract: A human system operator is guided through procedures relative to workpiece objects in real space by a machine-executable procedure program including procedure instructions related to the real-space operations. A spatial-positioning system tracks the locations and orientations within a defined physical space of workpiece objects and tools required to perform procedure steps relative to the workpiece objects. Machine-generated indicia related to sequential procedure steps are presented to the system operator through a mixed-reality headset. The machine generated indicia illustratively include graphical objects and textual instructions that convey to the system user information relative to a procedure step, such as which tool to use to act on which workpiece object, and the operation to be performed on each workpiece object. The system operator contemporaneously views both (i) the physical space and (ii) selected machine-generated indicia such that the machine-generated indicia, from the perspective of the system user, are superimposed over real space.

Title: Single-supply multi-level rf power amplifier supply modulation
Inventor: CAPPELLO TOMMASO
IPC: H03F1/02
Filed: 2019-05-07
Abstract: A multi-level supply modulator for RF power amplifiers requires only a single independent voltage supply along with one or more flying capacitors to achieve multiple output levels. The flying capacitor is used to store the intermediate voltage level between the DC supply level and ground. A switch network is connected between the DC voltage supply and the power amplifier and is configured to provide power at variable, discrete DC voltages, for example the DC voltage supply level, ground, and a level halfway between the DC voltage supply level and ground. The flying capacitor is connected to switches in the switch network, and a sensing circuit detects the voltage across the flying capacitor and generates a feedback signal. Control circuitry controls the switch network (and thus the power supplied to the amplifier) based on the feedback signal.

Title: Preparation of bimodal rubber, thermoplastic vulcanizates, and articles made therefrom
Inventor: TSOU ANDY
IPC: C08F4/6592
Filed: 2019-07-02
Abstract: Pellet-stable olefmic copolymer bimodal rubber is made using parallel reactors, with one reactor synthesizing higher molecular weight (MW) rubber with dual catalysts, with an improved molecular weight split ratio and an improved composition distribution of the moderate and ultra-high MW components, while another reactor synthesizes random isotactic polypropylene copolymer (RCP). The effluents are reactor-blended and result in pellet-stable bimodal rubber (P-SBR), which may be pelletized. When making thermoplastic vulcanizates (TP Vs) with P-SBR, the need to granulate rubber bales and subsequently use talc, clay, or other anti-agglomeration agents to prevent granulated rubber crumbs from agglomerating are eliminated. TPV s made with P-SBR have vulcanized rubber particles that are smaller and more uniform in size, resulting in TPVs with higher particle counts and more thermoplastic "ligaments" between the particles, with such ligaments being made stronger by the added RCP. Such thus-produced TPVs have a lower hysteresis and flexural modulus, and better elastic properties.

Abstract: A light detection and ranging (LIDAR) system 500 is provided that includes first and second optical scanning mirrors 506, 508 to steer a laser beam emitted from the tip of an optical fiber 504 to scan a scene 510, and collect light incident upon any objects in the scene that is returned to the fiber tip 504. The LIDAR system 500 further includes a re-imaging lens 512 located between the optical fiber and scanning mirror 506, and an optic 514 located between the scanning mirror and the scene. The re-imaging lens 512 focuses the laser beam emitted from the optical fiber 504 on or close to the first scanning mirror's center of rotation and thereby re-image the fiber tip at or close to the center of rotation, from which the laser beam is reflected as a divergent laser beam. And the optic is configured to collimate or focus the divergent laser beam from the first scanning mirror 506 that is launched toward the scene 510. The first and second scanning mirrors 506, 508 rotate along orthogonal axes to steer the laser beam across the scene 510 according to a scanning pattern. In some examples, the first scanning mirror 506 is rotatable with a faster angular velocity than the second scanning mirror 508 to scan the scene 510 according to a scanning pattern. In some examples, the optic is a collimator 514 which may alternatively be located between the second scanning mirror 508 and the scene 510. In other examples, the collimator 514 may be replaced with a focus lens configured to focus the divergent laser beam from the scanning mirror to produce a focused laser beam.
