  • Publication number: 20220381582
    Abstract: A method including receiving a request associated with one or more map views associated with a map, transmitting a first set of one or more map views, generating a display of at least one of the first set of one or more map views, receiving a user input associated with the display of the at least one of the first set of one or more map views, and receiving a message associated with the user input. The method may include deter mining a mapping context function based on the received message, the mapping context function being based on one or more user actions associated with one or more features on at least one previously accessed map, determining whether to modify a second set of one or more map views based on the mapping context function, and transmitting the second set of one or more map views.

  • Patent number: 11352124
    Abstract: Continuous skin leading edge slats are disclosed. A disclosed example leading edge slat for use with an aircraft includes a single-piece nose skin defining upper and lower external surfaces of the leading edge slat, where the single-piece nose skin is to extend between a fore end and an aft end of the leading edge slat, and a box spar coupled to an inner surface of the single-piece nose skin. The box spar includes lateral walls extending away from the inner surface of the single-piece nose skin. The lateral walls define at least one compartment of the box spar.

  • Patent number: 11285652
    Abstract: A no solid bed extruder screw for processing a material to a molten state has a body with a helical thread formed thereon, the thread having pushing and trailing surfaces. The body has an outer surface and extends longitudinally between feed and discharge ends. A channel for receiving the material to be processed is defined between the outer surface of the body and an outer diameter of the thread bounded by the pushing surface and the trailing surface of the thread. A volume of the channel decreases in a plurality of revolutions of the thread in a direction from the feed end to the discharge end. A channel depth between the pushing surface and the trailing surface decreases for a first portion of the channel toward the feed end and increases for a second portion of the channel toward the discharge end.

  • Publication number: 20190082769
    Abstract: A helmet for wearing by a sports player comprises: a bubble-shaped body having a hollow interior surrounded by a wall and an opening formed in the wall for inserting a head of the player, and a fastening device for releasably fastening the body to shoulder pads being worn by the player. At least a portion of the wall is formed of a transparent material. Alternate designs are also disclosed, including a helmet constructed of a plastic-coated wireframe, and a non-transparent plastic helmet with a face mask, where in all cases the helmet is rigidly but releasably attached to a chest pad or shoulder pad worn by the player, so that impact forces on the helmet are not transferred to the player's head.

  • Patent number: 9978395
    Abstract: A communication component modifies production of an audio waveform at determined modification segments to thereby mitigate the effects of a delay in processing and/or receiving a subsequent audio waveform. The audio waveform and/or data associated with the audio waveform are analyzed to identify the modification segments based on characteristics of the audio waveform and/or data associated therewith. The modification segments show where the production of the audio waveform may be modified without substantially affecting the clarity of the sound or audio. In one embodiment, the invention modifies the sound production at the identified modification segments to extend production time and thereby mitigate the effects of delay in receiving and/or processing a subsequent audio waveform for production.

  • Publication number: 20180079126
    Abstract: A plastic melt machine includes a feed screw rotatably mounted in a barrel and driven in rotation about a longitudinal screw axis of the feed screw by a screw drive to plasticize material, and an apparatus for driving a device independently of the feed screw. The device can be any rotatable device associated with the feed screw wherein the device is rotatable about a drive axis and is in fluid communication with the barrel to receive the plasticized material. The drive axis is coaxial with the screw axis. A drive shaft couples the device to the device drive, or to the screw drive through a speed changer, for rotating the device independently of the rotation of the feed screw by the screw drive.
