Abstract: This disclosure provides methods, components, devices and systems for announcing opportunistic primary channel switching. Various aspects generally relate to a channel switch announcement (CSA) element that may announce an opportunistic primary (O-Primary) channel switch. Various aspects relate more specifically to an expanded channel switch mode field of a CSA element that may indicate whether a wireless station (STA) is permitted to transmit via the first O-Primary channel during the switch, whether a new operating class field is present in the CSA element, and an index associated with the switched O-Primary channel. In some aspects, the CSA element may be a separate information element, or an element defined within a non-primary channel access (NPCA) wrapper. The AP may transmit the CSA element via a beacon frame, a probe response frame, or a dedicated channel switch announcement frame.

Abstract: A non-dispersive near infrared light is used for detecting analyte gases in a testing zone. A sample obtained from the testing zone is irradiated with a reference light and with test lights. The test lights are emitted in sequence and modulated to be out of phase with the reference light. Frequencies of the test lights are in the absorption bands of particular analyte gases, with the reference light frequency being outside of the absorption bands. Analyte presence in the sample is identified by sensing changes in differences over time of test light and reference light intensity. Before irradiating the sample, the lights are optically conditioned by aligning them on the same path, and splitting the bandwidth of some lights for detecting analytes with overlapping absorption bands.

Abstract: Systems and methods for communicating information acoustically through a plug in a temporarily or permanently abandoned well. The disclosed embodiments use an acoustically transmissive well plug, where an acoustic transmitter coupled to a measurement tool below the plug is coupled to the plug In a manner that is intended to maximize the coupling of the generated acoustic signals to the plug. These signals are then transmitted through the acoustically transmissive plug to an acoustic receiver that is coupled to the upper end of the plug. The acoustic receiver converts the acoustic signals to another form if necessary and forwards the signals to equipment at the surface of the well, or to intermediate transceivers that can relay the signals to the surface.

Abstract: An apparatus and method for automatic splicing of rolls of sleeve material used in various packaging applications. The disclosed system will automatically splice the leading end of a new roll onto the trailing end of the old roll in an overlapped configuration. The apparatus performs an automatic cut and splice operation resulting in a splice of the two film rolls with tape applied to both sides of the splice joint where the new roll overlaps the cut end of the prior roll.

Abstract: Systems and methods for low-manganese welding alloys are disclosed. An example arc welding consumable may comprise: between 0.4 and 1.0 wt % manganese; strengthening agents selected from the group consisting of nickel, cobalt, copper, carbon, molybdenum, chromium, vanadium, silicon, and boron; and grain control agents selected from the group consisting of niobium, tantalum, titanium, zirconium, and boron. The grain control agents may comprise greater than 0.06 wt % and less than 0.6 wt % of the welding consumable. The resulting weld deposit may comprise a tensile strength greater than or equal to 70 ksi, a yield strength greater than or equal to 58 ksi, a ductility (as measured by percent elongation) of at least 22%, and a Charpy V-notch toughness greater than or equal to 20 ft-lbs at ?20° F. The welding consumable may provide a manganese fume generation rate less than 0.01 grams per minute during the arc welding operation.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device (e.g., station (STA), access point (AP)) may transmit to a second wireless device during a service period, an initiating frame using a transmit beam that is based on a first beam training procedure performed between the devices prior to the service period. The first wireless device may perform a second beam training procedure during the service period based on an absence of a response frame from the second wireless device, based on an indication within the response frame received from the second wireless device, or based on identification of a change in a wireless channel relative to a previous beam training interval or previous service period. The first wireless device may then communicate one or more messages with the second wireless device using one or more beams that are based on the second beam training procedure.

Abstract: A pool double safety cover with at least one protection protocol includes a first cover that is substantially impermeable to water, and a second cover that is substantially permeable to water. A track system having independent parallel tracks is provided for guiding the first cover and the second cover to open and close over a pool. At least one interlock switch is configured to generate a signal indicating whether the first cover and the second cover is in a fully open or fully closed state. A drive system is configured to open and close the first cover and the second cover over the pool according to a protection protection protocol based on feedback from the interlock switch and at least one sensor. In another example, the protection protocol is a freeze protection protocol. In another example, the protection protocol is a precipitation protection protocol.

Abstract: Provided herein are ready-to-use premixed pharmaceutical compositions of nicardipine or a pharmaceutically acceptable salt and methods for use in treating cardiovascular and cerebrovascular conditions.

Abstract: The subject invention pertains to a method for identifying G-quadruplexes (G4s) in a cell using a G4 fluorescent probe, 2-(2-hydroxy-6-methoxy-3-propionylphenyl)quinazolin-4(3H)-one (HMPQ), which exhibits specific binding affinity to G-quadruplexes (G4s), illuminating these non-canonical nucleic acid structures without altering their conformation. G4s are involved in chromatin organisation, gene regulation, genome stability, and appear to contribute to cancer growth and progression. By utilizing HMPQ's unique fluorescence mechanism through excited-state intramolecular proton transfer, the method allows label-free precise detection of G4 structures in the nucleus of a cell.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiver device may receive a management frame addressed to the receiver device; parse the management frame to identify a link identifier included in the management frame; associate the link identifier with link information included in the management frame; and update, based at least in part on the link information, a communication configuration for a link identified by the link identifier. Numerous other aspects are provided.

Abstract: A youth javelin having a tip, a shaft, a handle and a tail wherein the overall length of the youth javelin is in the range of 135 cm to 148 cm, the weight is in the range of 240 g and 265 g, has a balance point in the range of 57 cm and 60 cm measured from the forward end of the tip, and a weight-to-surface-area ratio in the range of 0.2000 g/cm2 to 0.2585 g/cm2.

Abstract: Aspects of the present disclosure provide for techniques enabling streamlined cross application content delivery by enabling a feature, along with a first application, to search, locate, and transmit data corresponding to a second application. For example, a user may utilize a smartphone, laptop, or some other device, to access the first application (e.g., email). The user may determine to transmit a document, which may be stored within a cloud-based database corresponding to a second application. Instead of switching from email to the second application, the first user may utilize the feature to search for, locate, and transmit the document within the first application. In some cases, the document may be transmitted as a uniform resource locator (URL), where the URL corresponds to a link to the document within the cloud-based database. Additionally or alternatively, the document may be transmitted as an attachment.
