Abstract: An apparatus includes an encoder, which receives image or video data, encodes the data and provides a bitstream representing the data. The encoder includes a CABAC encoder, which receives a binary valued syntax element associated with a block of the data to be encoded, and encodes, using a selected context model, the syntax element into coded bits for the bitstream. The syntax element includes a tool flag indicating whether or not certain coding tool, like linear weighted intra prediction, is employed when encoding a block of the data. For a block of the data which exhibits an aspect ratio larger than 2 and for a block of the data which exhibits an aspect ratio less than or equal to 2, and to which blocks the certain coding tool is applicable, first and second context models for encoding the tool flag are selected from a group of one or more first and second context models, respectively.

Abstract: Media, systems, and methods for reducing latency in a head-mounted display for the remote operation of machinery. A remote camera sends raw video to a graphics processing unit which processes the video and transmits the updated video to a head-mounted display with limited latency such that the control of remote devices may be improved. The image may be spherically rendered and projected onto the head-mounted display with a rectangular view. The graphics processing unit may determine a rotation matrix based on a pose of the remote camera and a pose of the head-mounted display, and the image may be projected based on the rotation matrix.

Abstract: A system described herein may provide a technique for maintaining and implementing a dynamic uplink grant policy for a User Equipment (“UE”) connected to a base station of a radio access network (“RAN”) of a wireless telecommunications network. The dynamic uplink grant policy may be based on historical utilization of radio frequency (“RF”) resources granted to the UE, which may be based on a historical amount of padding (e.g., versus user plane data) included in uplink transmissions from the UE to one or more base stations associated with the wireless telecommunications network. The dynamic uplink grant policy may indicate an amount by which resource grants for a UE should be reduced, compared to an amount of resources requested by the UE.

Abstract: A head-mounted device (HMD) can be configured to determine a request for recognizing at least one content item included within content framed within a display of the HMD. The HMD can be configured to initiate a head-tracking process that maintains a coordinate system with respect to the content, and a pointer-tracking process that tracks a pointer that is visible together with the content within the display. The HMD can be configured to capture a first image of the content and a second image of the content, the second image including the pointer. The HMD can be configured to map a location of the pointer within the second image to a corresponding image location within the first image, using the coordinate system, and provide the at least one content item from the corresponding image location.

Abstract: Disclosed are electrochemical reactors with electrodes that have variable porosity across the electrode. The electrodes are designed and micro-architected to have variable porosity and 3D flow. In one aspect, an electrochemical cell apparatus is disclosed. The apparatus includes an electrochemical vessel and an electrochemical fluid contained in the electrochemical vessel. The apparatus further includes a porous electrode submerged in the electrochemical fluid in the electrochemical vessel, the porous electrode having different porosities in different areas of the porous electrode. The different porosities inhibit electrochemical fluid flow and increase electrical conductivity in first areas of the porous electrode with decreased porosity compared to second areas, and enable increased electrochemical fluid flow and decrease electrical conductivity in the second areas of the porous electrode with increased porosity compared to the first areas.

Abstract: A speech recognition engine is provided voice data indicative of at least a brand of a target appliance. The speech recognition engine uses the voice data indicative of at least a brand of the target appliance to identify within a library of codesets at least one codeset that is cross-referenced to the brand of the target appliance. The at least one codeset so identified is then caused to be provisioned to the controlling device for use in commanding functional operations of the target appliance.

Abstract: Ablation probes and methods of their use. Example probes include probe circuits configured to provide identifying information for the probe itself. The probe circuits may sense probe usage and/or age to determine probe end of life (EOL). In response to EOL, the probe circuit generates an output indicating EOL. The probe electronic circuit may also be configured to monitor probe usage via impedance or other features, independent of such operation by an ablation pulse generator.

Abstract: In examples, the number of rays used to sample lighting conditions of a light source in a virtual environment with respect to particular locations in the virtual environment may be adapted to scene conditions. An additional ray(s) may be used for locations that tend to be associated with visual artifacts in rendered images. A determination may be made on whether to cast an additional ray(s) to a light source for a location and/or a quantity of rays to cast. To make the determination variables such as visibilities and/or hit distances of ray-traced samples of the light source may be analyzed for related locations in the virtual environment, such as those in a region around the location (e.g., within an N-by-N kernel centered at the location). Factors may include variability in visibilities and/or hit distances, differences between visibilities and/or hit distances relative to the location, and magnitudes of hit distances.

Abstract: A method of controlling a wrap system of a round baler includes determining a current characteristic of a supply roll of wrap material related to a current weight of the supply roll, and controlling rotation of a pair of spool rollers based on the current characteristic of the supply roll. As the current characteristic indicates a decrease in weight, the rotation of the pair of spool rollers is controlled to achieve a desired acceleration rate of the spool rollers, such that a leading edge of the wrap material is ejected from a nip formed between the pair of spool rollers at an ejection trajectory that is within an allowable angular range relative to a tangent of the nip, so that the leading edge of the wrap material passes through an access and into a baling chamber of the round baler.

Abstract: An end effector for use by a surgeon to staple an anatomical structure of a patient during a surgical procedure includes an anvil and a cartridge. The anvil has an anvil face and a first staple pocket defined by the anvil face, where the first staple pocket comprises a first cup and a second cup for staple formation. The cartridge has a first staple, the first staple having a first open leg with a first tip, a second open leg with a second tip, and a first crown coupling the first open leg and the second open leg, and a first driver. The first staple, once deployed by the first driver and deformed by the first staple pocket, comprises the first tip and the second tip crossing the first midline axis of the first crown in a formed configuration.

Abstract: A range limiter to secure or position a adjustable height, foldable table at a particular height. A two-way spring-loaded plunger is positioned at the end of a leg for engagement with a stop component. The stop component is affixed to the bottom of the table top. When the leg is in a storage position, the plunger is pushed outward preventing the table leg from opening too far. The two springs have different forces or strengths associated with them. An extension section of the leg pushes against a heavy spring when the table is collapsed, thereby pushing the plunger outward. A light spring keeps the plunger withdrawn when the leg is extended.
