  • Patent number: 10780298
    Abstract: Apparatus and methods are provided for applying ultrasound pulses into tissue or a medium in which the peak negative pressure (P?) of one or more negative half cycle(s) of the ultrasound pulses exceed(s) an intrinsic threshold of the tissue or medium, to directly form a dense bubble cloud in the tissue or medium without shock-scattering. In one embodiment, a microtripsy method of Histotripsy therapy comprises delivering an ultrasound pulse from an ultrasound therapy transducer into tissue, the ultrasound pulse having at least a portion of a peak negative pressure half-cycle that exceeds an intrinsic threshold in the tissue to produce a bubble cloud of at least one bubble in the tissue, and generating a lesion in the tissue with the bubble cloud. The intrinsic threshold can vary depending on the type of tissue to be treated. In some embodiments, the intrinsic threshold in tissue can range from 15-30 MPa.

  • Publication number: 20200154457
    Abstract: Examples pertaining to improvement on user equipment (UE) uplink latency in wireless communications are described. When an apparatus is in a special mode, a processor of the apparatus transmits to a network a request for permission to perform an uplink (UL) transmission for a plurality of times. The processor then receives from the network a grant. In response to receiving the grant, the processor performs the UL transmission to the network. In transmitting the request for the plurality of times, the processor transmits the request for the plurality of times at a frequency higher than a frequency at which the request to perform UL transmissions is transmitted to the network when the apparatus is in a normal operational mode.

  • Publication number: 20200129542
    Abstract: The present invention discloses a branched polyethylene glycol epoxy derivative crosslinked sodium hyaluronate gel, preparation and application thereof. The crosslinking agent used in the crosslinked sodium hyaluronate gel prepared by the present invention is a polyethylene glycol epoxy derivative, due to the existence of multiple ether bonds in the molecule of the crosslinking agent, there are more hydrogen bonds in the gel system; meanwhile, due to the particularity of the space structure of the branched polyethylene glycol epoxy derivative, the gel prepared has a more complex winding structure in its space, thus achieving better stability. Moreover, the branched polyethylene glycol epoxy derivative involved in the present invention is a compound with single molecular weight, therefore, the gel prepared thereby has better batch stability.

  • Patent number: 10607646
    Abstract: A method includes moving a heat-assisted magnetic recording (HAMR) slider relative to a magnetic recording medium. The slider comprises a writer, a writer heater, and a near-field transducer (NFT). For each of a plurality of different head-to media spacings a test tone is written to a track of the medium, the test tone is read and a Discrete Fourier Transform (DFT) of an amplitude of the read test tone is captured. A first DFT curve is generated at a beginning of writing the test tones. A second DFT curve is generated at a saturated state of writing the test tones. An amount of horizontal shift between the first and second DFT curves is computed. The amount of horizontal shift corresponding to writer heater power required to compensate for NFT clearance offset due to laser induced writer protrusion.
