  • Patent number: 11024017
    Abstract: A system and methods is provided for performing, by a processor, an initial tone mapping function on a first image to produce a second image. The first and second images are of different dynamic ranges. The method also includes applying, by the processor, a second tone mapping function to the second image when it contains any saturated portions. The second tone mapping function lowers luminance by a first fraction. The overall luminance of the second image is also determined and a fine tuning filter is applied when at least portions of said second image contain areas darker than an amount.

  • Patent number: 10942378
    Abstract: A pupil-replicating waveguide suitable for operation with a coherent light source is disclosed. A waveguide body has opposed surfaces for guiding a beam of image light. An out-coupling element is disposed in an optical path of the beam for out-coupling portions of the beam at a plurality of spaced apart locations along the optical path. Electrodes are coupled to at least a portion of the waveguide body for modulating an optical path length of the optical path of the beam to create time-varying phase delays between the portions of the beam out-coupled by the out-coupling element.

  • Patent number: 10913470
    Abstract: A railcar steering bogie includes a bogie frame, a wheelset, an axle box suspension, a steering mechanism configured to steer the wheelset, a brake unit, and a brake unit support link. The brake unit includes: a main body frame; a brake shoe supported by the main body frame and pressed against a wheel tread of the wheel during braking. The brake unit support link couples the axle box suspension and the brake unit and transmits displacement of the axle box in a car longitudinal direction to the brake unit at least during steering performed by the steering mechanism. The brake unit support link restricts the brake unit from being displaced outward in a car width direction by a predetermined distance or more during the braking. At least one of a side surface of the brake unit support link and a side surface of the brake unit includes a sliding surface.

  • Patent number: 10848613
    Abstract: Apparatuses and methods that generate and send interactive elements to a plurality of wearable electronic devices are discussed. One or more mobile applications and one or more remote backend servers may cooperate to send information in the interactive elements to the instances of the time synchronous application resident in their wearable electronic device in order to bring different types of content such as timely and relevant data, events, and notifications to a user of that wearable electronic device without the user's intervention to actively retrieve the different types of content. The interactive elements may be generated and sent from any of i) a public application programming interface hosted on a server, ii) one or more mobile applications resident on one or more mobile computing devices, and iii) one or more remote backend servers. In addition, these sources may merely send content and commands for the interactive elements to the public application programming interface.
