  • Publication number: 20190385466
    Abstract: Systems, computer-implemented methods and/or computer program products that facilitate generating aircraft performance volume based on collision avoidance are provided. In one embodiment, a system utilizes a processor that executes computer implemented components stored in a memory. A graph component uses flight management data to plot course of flight for a determined period of time. A deviation component calculates a volume of space of aircraft performance that is capable of deviating from the course of flight based on current aircraft configuration and capability. A search component searches for intersections between the volume of space of the aircraft with broadcasted volume of space of other aircrafts to identify potential collisions.

  • Patent number: 10509155
    Abstract: Systems, devices, and methods that implement waveguides in curved transparent combiners that are well-suited for use in wearable heads-up displays (WHUDs) are described. Waveguide structures with in-couplers and out-couplers are integrated with curved eyeglass lenses to provide transparent combiners that substantially match the shape, size, and geometry of conventional eyeglass lenses and can, in some implementations, embody prescription curvatures to serve as prescription eyeglass lenses. The waveguides and in-/out-couplers are planar or curved depending on the implementation. WHUDs that employ such curved transparent combiners are also described.

  • Publication number: 20190372975
    Abstract: Systems and methods for authenticating data transmissions are provided, such as e.g., analog radio streams received at a vehicle. In one aspect, the vehicle includes features that allow for detection and decryption of an encrypted source identifier embedded or introduced into a data transmission transmitted to the vehicle. The source identifier may be used to determine whether the source is authorized to transmit data transmissions to the vehicle and the data transmission may be authenticated accordingly. In another aspect, the vehicle includes features that determine the location of the transmitting device used to transmit the data transmission to the vehicle. The location is then used to determine whether the data transmission should be authenticated.

  • Patent number: 10459222
    Abstract: Systems, devices, and methods for laser projectors with variable luminance that are well-suited for use in a wearable heads-up display (“WHUD”) are described. Such laser projectors include a laser light source(s) and a scan mirror(s) to generate an image in the field of view of a user, and a liquid crystal element between the light source(s) and the scan mirror(s) to adjust the luminance of the image. The liquid crystal element is on an optical path between the laser light source(s) and the scan mirror and is communicatively coupled to a controller that modulates an opacity of the liquid crystal element. The opacity of the liquid crystal element determines the luminance of the image and may be altered in response to different factors, such as ambient light.

  • Patent number: 10429655
    Abstract: Systems, devices, and methods that integrate eye tracking capability into scanning laser projector (“SLP”)-based wearable heads-up displays are described. At least one narrow waveband laser diode is used in an SLP to define one or more portion(s) of a visible image. At least one corresponding narrow waveband photodetector is aligned to detect reflections of the portion(s) of the image from features of the eye. A holographic optical element (“HOE”) may be used to combine the image and environmental light into the user's “field of view.” Three narrow waveband photodetectors each responsive to a respective one of three narrow wavebands output by the RGB laser diodes of an RGB SLP are aligned to detect reflections of a projected RGB image from features of the eye.

  • Publication number: 20190237026
    Abstract: A voltage-programmed display system allows measurement of effects on pixels in a panel that includes both active pixels and reference pixels coupled to a supply line and a programming line. The reference pixels are controlled so that they are not subject to substantial changes due to aging and operating conditions over time. A readout circuit is coupled to the active pixels and the reference pixels for reading at least one of current, voltage or charge from the pixels when they are supplied with known input signals. The readout circuit is subject to changes due to aging and operating conditions over time, but the readout values from the reference pixels are used to adjust the readout values from the active pixels to compensate for the unwanted effects.

  • Patent number: 10310271
    Abstract: Systems, devices, and methods that implement waveguides in curved transparent combiners that are well-suited for use in wearable heads-up displays (WHUDs) are described. Curved transparent combiners employ an optical lens or optical lens blank with a waveguide or light guide embedded therein and with low refractive index materials interposed between one or more major surfaces of the waveguide and the optical lens or blank to facilitate total internal reflection while the waveguide is embedded in the lens. The curved transparent combiners may optionally include in-couplers and/or out-couplers to provide transparent combiners that substantially match a shape, size, and geometry of conventional eyeglass lenses and can, in some implementations, embody prescription curvatures to serve as prescription eyeglass lenses. The waveguides and in-/out-couplers are planar or curved depending on the implementation. WHUDs that employ such curved transparent combiners are also described.

  • Publication number: 20190129676
    Abstract: Systems, devices, and methods for wearable computer systems are described. A wearable heads-up display (“WHUD”) is implemented as a peripheral to a wearable electronic band worn on a limb of the user. The majority (or all) of the application storage and processing is performed on the band instead of on the WHUD, and therefore the WHUD does not include all of the hardware infrastructure necessary for application storage and processing. This significantly reduces the bulk of the WHUD and enables more aesthetically pleasing WHUD designs. Graphics processing is also performed on the band instead of on the WHUD. In some implementations, rasterized display data is wirelessly transmitted from the band to the WHUD using an ultra-wideband wireless communication scheme. Gesture-based control of content displayed by the WHUD is enabled by sensors on-board the band itself or by a third wearable component in communication with the band.
