  • Publication number: 20190320998
    Abstract: Apparatus and methods of use are provided for complex flow imaging and analysis that is non-invasive, accurate, and time-resolved. It is particularly useful in imaging of vascular flow with spatiotemporal fluctuations. This apparatus is an ultrasound-based framework called vector projectile imaging (VPI) that can dynamically render complex flow patterns over an imaging view at millisecond time resolution. The VPI apparatus and methods comprise: (i) high-frame-rate broad-view data acquisition (based on steered plane wave firings); (ii) flow vector estimation derived from multi-angle Doppler analysis (coupled with data regularization and least-squares fitting); and (iii) dynamic visualization of color-encoded vector projectiles (with flow speckles displayed as adjunct).

  • Patent number: 10455608
    Abstract: Disclosed embodiments include methods for control channel design in many-antenna multi-user (MU) multiple-input multiple-output (MIMO) wireless systems. A beacon comprising an identifier of a many-antenna base station is encoded into a base sequence. A plurality of synchronization sequences is generated based on the encoded base sequence and a set of orthogonal beam sequences. The many-antenna base-station transmits, using a plurality of antennas, the plurality of synchronization sequences in a plurality of beam directions associated with the set of orthogonal beam sequences for synchronization and associated with users without knowledge of channel state information (CSI).

  • Publication number: 20190157077
    Abstract: Embodiments described herein relate to methods of forming silicon nitride films. In one embodiment, a first process gas set including a silicon-containing gas and a first nitrogen-containing gas is flowed into the process chamber. An initiation layer is deposited by applying a first radio frequency power to the first process gas set at a first frequency and a first power level. The first flow of the first nitrogen-containing gas of the first process gas set is discontinued and a second process gas set including the silicon-containing gas, a second nitrogen-containing gas, and a hydrogen-containing gas is flowed into the process chamber. A bulk silicon nitride layer is deposited on the initiation layer by applying a second RF power to the second process gas set at a second frequency higher than the first frequency and a second power level higher than the first power level.

  • Publication number: 20190153592
    Abstract: Embodiments of the invention contemplate a shadow ring that provides increased or decreased and more uniform deposition on the edge of a wafer. By removing material from the top and/or bottom surfaces of the shadow ring, increased edge deposition and bevel coverage can be realized. In one embodiment, the material on the bottom surface is reduced by providing a recessed slot on the bottom surface. By increasing the amount of material of the shadow ring, the edge deposition and bevel coverage is reduced. Another approach to adjusting the deposition at the edge of the wafer includes increasing or decreasing the inner diameter of the shadow ring. The material forming the shadow ring may also be varied to change the amount of deposition at the edge of the wafer.

  • Patent number: 10268941
    Abstract: The present disclosure provides a smart card information querying method, including: sending a terminal configuration request to a server, so that the server determines, according to the terminal configuration request, whether a terminal configuration file cached in a terminal needs to be updated, wherein the terminal configuration file is configured based on a geographical area indicated by a smart card and is used for querying smart card information; receiving an update file delivered by the server, when the server determines that the terminal configuration file cached in the terminal needs to be updated; updating the terminal configuration file cached locally according to the update file delivered by the server; and when a connection is established to the smart card in a short-distance communications mode, querying card information of the smart card according to the updated terminal configuration file.

  • Patent number: 10207183
    Abstract: Example apparatus and methods concern establishing, maintaining, managing, or terminating communications between an access point and a client in a wireless network used by a shared, wireless gaming system. An example apparatus may include a first logic configured to control timing for the protocol and a second logic configured to control message exchange for the protocol. Controlling timing and message exchange facilitates reducing contention in the wireless gaming environment. Contention may lead to latency. A user gaming experience may depend on reducing latency. Therefore, reducing latency may produce an improved gaming experience. Controlling timing and message exchange also facilitates reducing power consumption by clients (e.g., accessories, controllers), which in turn facilitates improving battery life for clients.

  • Patent number: 10018623
    Abstract: Described are metal complexes for the selective detection of ascorbic acid or ascorbate. The metal complexes act as molecular sensors, and are useful in detecting ascorbate in live biological samples, commercial samples, or both. The selective ascorbate sensing involves an ascorbate-selective bond cleavage reaction. The bond cleavage is not limited to the construction of molecular sensors, but also includes other stimuli-responsive materials, i.e., materials that adopt a physical state, such as gel formation, upon ascorbate-selective bond cleavage of the metal complexes.
