  • Publication number: 20250018176
    Abstract: In some examples, an endovascular medical device system includes an elongated body configured to be introduced in a blood vessel of a patient. The system includes an expandable structure at a distal portion of the elongated body. The expandable structure includes an expandable body portion including a plurality of interconnected struts. The expandable structure further includes a plurality of electrode attachment elements, where each electrode attachment element of the plurality of electrode attachment elements includes a first projection and a second projection branching off of at least one strut of the plurality of interconnected struts. In some examples, the system includes one or more electrodes coupled to the expandable structure via the plurality of electrode attachment elements. In some examples, each electrode of the one or more electrodes is configured to receive the first projection and the second projection to couple the respective electrode to the expandable structure.

  • Publication number: 20240331611
    Abstract: Embodiments herein provide various apparatuses and techniques to efficiently mitigate front-of-screen (FoS) artifacts that may occur due to voltage fluctuations due to alternating current (AC) or direct current (DC) mechanisms that may occur in a variety of pixel types. In one embodiment, emission profile awareness circuitry may be implemented to mitigate for FoS artifacts due to DC mechanisms. Two-dimensional (2D) digital compensation circuitry may address the DC portion of the voltage fluctuations by accounting for an emission profile applied to content displayed on an electronic display. In some embodiments, the 2D digital compensation circuitry may compensate for the AC portion of the voltage fluctuations by duplicating the AC voltage fluctuations via voltage error subtraction circuitry and voltage error accumulation circuitry.

  • Patent number: 11993836
    Abstract: Disclosed are an R—Fe—B-based sintered magnet with a low B content and a preparation method therefor. The sintered magnet comprises the following components: 28.5 wt %-31.5 wt % of R, 0.86 wt %-0.94 wt % of B, 0.2 wt %-1 wt % of Co, 0.2 wt %-0.45 wt % of Cu, 0.3 wt %-0.5 wt % of Ga, 0.02 wt %-0.2 wt % of Ti, and 61 wt %-69.5 wt % of Fe. The sintered magnet has an R6-T13??M1+? series phase accounting for 75% or more of the total volume of grain boundaries. The present invention selects optimal content ranges of R, B, Co, Cu, Ga, and Ti, and forms an R6-T13??M1+? series phase of a special composition and increases its volume fraction in grain boundary phases, so as to acquire higher Hcj and SQ values.

  • Patent number: 11810494
    Abstract: An electronic device may include an electronic display having multiple display pixels to display an image based on analog voltage signals. The electronic device may also include optical calibration circuitry to generate digital-to-analog converter (DAC) data based on image data associated with the image and dither circuitry to reduce a bit-depth of the DAC data, generating dithered DAC data. Additionally, the electronic device may include a gamma generator having one or more DACs to generate the analog voltage signals based on the dithered DAC data, which may instruct the gamma generator to generate the analog voltage signals indicative of the image data.

  • Patent number: 11756481
    Abstract: Systems, methods, and devices are provided for mitigating visual artifacts by dynamically tuning bias voltages applied to display pixels. An electronic display may include a display pixel and a bias voltage supply. The bias voltage supply may supply a first bias voltage to the display pixel for a first subframe of a frame of image data. The bias voltage supply may supply a different second bias voltage to the display pixel for a second subframe of the frame of image data. This may mitigate certain image artifacts, such as flicker or variable refresh rate luminance difference, that could arise due to display pixel hysteresis that varies across subframes of the image frame.

  • Publication number: 20230093094
    Abstract: Disclosed in the present invention are a heavy rare earth alloy, neodymium-iron-boron permanent magnet material, a raw material, and a preparation method. The heavy rare earth alloy comprises the following components: RH: 30-100 mas %, not including 100 mas %; X, 0-20 mas %, not including 0; B: 0-1.1 mas %; and Fe and/or Co: 15-69 mas %, RH comprising one or more heavy rare earth elements in Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, and Sc, and X being Ti and/or Zr. When the heavy rare earth alloy of the present invention is used as a sub-alloy to prepare the neodymium-iron-boron permanent magnet material, a high utilization rate of heavy rare earth is achieved, so that the coercivity can also be greatly improved while the neodymium-iron-boron permanent magnet material maintains high remanence.

  • Publication number: 20230021772
    Abstract: An R-T-B-based sintered magnet and a preparation method therefor. The R-T-B-based sintered magnet comprises: R, B, Ti, Ga, Al, Cu, and T. The contents thereof are as follows: R is 29.0-33%; the content of B is 0.86-0.93%; the content of Ti is 0.05-0.25%; the content of Ga is 0.3-0.5%, but not 0.5%; the content of Al is 0.6-1%, but not 0.6%; the content of Cu is 0.36-0.55%. The percentage is the mass percentage. Under the condition that no heavy rare earth is added or a small amount of heavy rare earth is added, by using a low B technology, not only the remanence performance of the R-T-B-based sintered magnet is improved, but also the coercivity and the squareness of the magnet are ensured.

  • Patent number: 10911078
    Abstract: A millimeter-scale Bluetooth low energy wireless transmitter is presented with a dual purpose loop antenna. The oscillator employs a high quality factor resonator formed by a printed 3.5×3.5 mm2 inductive loop antenna (simulated Q˜110) and an on-chip digitally-switched capacitor array (simulated Q˜283). The oscillator replaces the traditional voltage controlled oscillator plus power amplifier, achieving lower power consumption while maintaining phase noise of ?118.5 dBc/Hz at 1 MHz offset that results in low FSK modulation error (2.1%) and low frequency drift during BLE packet transmission.
