  • Publication number: 20190238854
    Abstract: Examples described herein generally relate to performing frame extrapolation in image frame rendering. A vertex mesh as a set of vertices is generated, and each vertex is mapped to a screen space position for defining a texture. One or more motion vectors for one or more regions in a first image frame of a stream of image frames can be determined. The screen space positions associated with at least a portion of the set of vertices within the texture can be modified based at least in part on the one or more motion vectors. A graphics processing unit (GPU) can render the first image frame into the texture. The extrapolated image frame is displayed after the first image frame and before a next image frame in the stream of image frames.

  • Publication number: 20190203596
    Abstract: A method of moving waste material from a mining site using at least one excavator and a plurality of dozers, including excavating material with the at least one excavator from a dig area, said at least one excavator moving along an excavator path that is parallel with the dig area, transferring the excavated material to a plurality of slots, each of said slots are positioned at an angle to the excavator path, and pushing the transferred material by one of said plurality of dozers along the slot and away from the excavator path; wherein each slot allows each of the plurality of dozers to move between a proximal position and a distal position relative to the excavator path.

  • Publication number: 20170148341
    Abstract: A system for visual encoding of words to assist learning to read including systematic variations in the appearance of letters which may look like morphic analogs of the sound variations they suggest (for example, barely visible grey for silent letters). By improving how letters cue sounds (like the alphabet originally did), visual encoding reduces the cognitive processing work that most impedes and endangers the progress of beginning and struggling readers (disambiguating letter-sound relationship confusion).

  • Patent number: 6640489
    Abstract: A device is provided for the collection and disposal of insects and similarly sized detrital objects. The device includes an air inlet end through which air can be entrained, and an air outlet from which said entrained air is expelled. The device also includes a hollow duct portion through which entrained air passes and a filter means provided between the inlet and the outlet which prevent insects from being expelled through the outlet. Means are provided to create a pressure differential between the air inlet and air outlet of the device, such that air is entrained in the inlet and drawn through the duct portion of the device towards the outlet, additionally passing through the filter.

  • Patent number: 6500390
    Abstract: A microplate assembly comprising a multi-well microplate, a plurality of vent caps and a porous vent film. The microplate includes a frame that houses a plurality of open wells in a rectangular array. Vent caps mount on the microplate to seal and vent the wells. When the vent caps are coupled to the wells, an interior volume is formed in each well. The wells function as a vessel for liquid samples that occupy predetermined spaces within the interior volumes. Each liquid sample remains within its predetermined space for all orientations of the microplate assembly. The vent cap comprises an array of well inserts. Each well insert comprises a sealing plug and a vent tube. A flexible perforated web interconnects the well inserts to each other. The vent tubes are fixed to the sealing plugs and terminate in a vent. A barrier formed from a plurality of nested flaps resiliently mounts on the vent tube to partially cover the vent and help inhibit the evaporation and loss of the liquid samples.

  • Patent number: 5566291
    Abstract: A method and apparatus for implementing user feedback. A user may activate an enter feedback mode command in a computer environment to provide feedback in a feedback interface. A feedback record is created and the user's context within a product, process, service, or issue to which the feedback refers is recorded in the feedback record. Attribute icons that the user may select to identify the nature of the feedback are displayed in the feedback interface. Selected attributes, the time at which the feedback is made, the physical location and identity of the user, and comments by the user are recorded in the feedback record. A feedback visualizer for a reviewer for organizing and presenting user feedback receives feedback from users, the feedback being collected and stored in a database. The visualizer identifies a reviewer's visualization preferences, which include indications of feedback attributes that the reviewer desires to review.

  • Patent number: 5264355
    Abstract: Described is a new enzyme, 31-O-desmethyl-FK-506 O-methyltransferase (FKMT) and its N-terminal amino acid sequence. This enzyme can specifically and preferentially methylate the C-31 hydroxy group in 31-O-desmethyl FK-506/FR-900506 and other 31-O-desmethyl analogs of FK-506/FR-900506 and related compounds such as 31-O-desmethyl immunomycin type molecules, also designated FK-520 and FR-900520 by Fujisawa. The enzyme can be isolated from a FK-506 producing microorganism Streptomyces sp. (Merck Culture Collection No. MA 6858) ATCC No. 55098. Employing the enzyme in its active form, supplemented with Mg.sup.+2 ion, in the presence of the methyl donor, S-adenosyl methionine (SAM), derivatives of 31-O-desmethyl FK-506, 31-O-desmethyl FK-520 and related 31-O-desmethyl compounds may be prepared.

  • Patent number: 4985697
    Abstract: A method for compiling and presenting educational material on an electronic book is disclosed. A set of information requiring a first level of comprehension is created at a terminal or provided from a pre-existing data base. The set of information is examined for words which require a higher level of comprehension. Different types of explanatory information are created for such words and are tagged to the words so that they can be immediately called up when the word is later presented. The compiled first set of information at a first level of comprehension is a first modality. Additional modalities at different levels of comprehension or simply adjusted for different learning styles are also prepared. Each modality is cross-indexed to the other modality at a conceptual meaning level. The conceptual meaning level can be roughly a paragraph long block. The electronic book uses analog storage on a magnetic tape.

  • Patent number: 4937821
    Abstract: An information delivery system which continuously provides sets of information which can be selected by a user. Digital data is encoded as analog signals which are used to amplitude modulate a carrier signal. A plurality of such modulated carrier signals, each constituting a subchannel, are mixed together to form a single channel which can be delivered to a user over a cable or otherwise. The data provided on each carrier in the channel constantly repeats itself so that the entire set of data on a particular carrier wll be available to a user in a relatively short time regardless of the time of access by the user. A first subchannel contains an index to the remaining subchannels to allow user selection of a particular set of information.
