  • Publication number: 20230076071
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may filter leaked power from a signal to accurately perform antenna compensation operations (e.g., apply a transmit gain, perform cable loss measurements) using valid power. A switch at the UE may leak power to an antenna for a transmission, and the UE may use a dynamic filtering algorithm to determine whether a pulse power of a detected signal is leaked or valid. The dynamic filtering algorithm may be able to account for variations in leaked power values, as leaked power may increase or decrease proportionally to intended power (e.g., from which power was leaked). By determining whether pulse power is leaked or valid, the UE may be able to filter out the leaked power and accurately perform antenna compensation operations such as applying a transmit gain for a transmission, performing a cable loss measurement, or the like.

  • Publication number: 20220359758
    Abstract: Transistors with metal oxide channel material and a multi-composition gate dielectric. A surface of a metal oxide gate dielectric may be nitrided before deposition of a metal oxide channel material, for example to reduce gate capacitance of a TFT. Breakdown voltage and/or drive current of a TFT can be increased through the introduction of an additional metal oxide and/or nitride between the gate electrode and a metal oxide gate dielectric. The introduction of an intervening layer between two layers of a metal oxide gate dielectric can also increase breakdown voltage and/or drive current of a TFT.

  • Publication number: 20220147147
    Abstract: The present implementations relate to a support structure for an input device that supports deflection of an input surface responsive to input forces exerted thereon and vibration of the input surface responsive to haptic feedback generated by a haptic actuator. The support structure includes one or more fixed structures mounted to a housing and a dynamic surface mounted to a sensor layer of the input device. A number of first deformable segments cantilever from the one or more fixed surfaces and deflect in a vertical direction when an input force is exerted on the sensor layer, where the input force is orthogonal to the input surface. A number of second deformable segments connect the plurality of first deformable segments to the dynamic surface and deflect in a horizontal direction when shear forces are exerted on the dynamic surface, where the shear forces are parallel to the input surface.

  • Publication number: 20220006070
    Abstract: The present invention relates to a hydrogen storage alloy, an electrode for a Ni-MH battery, a secondary battery, and a method for preparing the hydrogen storage alloy. The chemical composition of the hydrogen storage alloy is expressed by the general formula La(3.0˜3.2)xCexZrySm(1?(4.11˜4.2)x?y)NizCouMnvAlw, where x, y, z, u, v, w are molar ratios, and 0.14?x?0.17, 0.02?y?0.03, 4.60?z+u+v+w?5.33, 0.10?u?0.20, 0.25?v?0.30, and 0.30?w?0.40. The atomic ratio of the metal lanthanum (La) to the metal cerium (Ce) is fixed at 3.0 to 3.2, which satisfies the requirements of the overcharge performance of the electrode material. A side elements are largely substituted by samarium (Sin) element, that is, the atomic ratio of Sin on the A side is 25.6% to 42%, so as to solve the problem of shortened cycle life caused by the small amount of cobalt (Co) atoms.

  • Publication number: 20210397809
    Abstract: A sensor assembly includes a cover layer and a first sensor apparatus. The cover layer is molded from a first material to have a planar surface and non-uniform thickness, where a thickness of the first material at a first region of the cover layer is less than a thickness of the first material surrounding the first region. The first sensor apparatus is disposed beneath the planar surface of the cover layer, within the first region. The first sensor apparatus is configured to transmit and receive first capacitive sensing signals through a portion of the planar surface coinciding with the first region. For example, the first sensor apparatus may be a fingerprint sensor configured to detect a fingerprint on the portion of the planar surface coinciding with the first region based on changes in the first capacitive sensing signals.

  • Patent number: 11140641
    Abstract: Aspects directed towards synchronizing out of coverage (OOC) vehicle-to-everything (V2X) communications are disclosed. In one example, a scheduled entity detects a loss of a synchronization signal associated with a V2X communication by detecting when a timing uncertainty value or error value is greater than a threshold value. Packet timing information is then received in response to the loss of the synchronization signal from at least one user equipment (UE) synchronized with the synchronization signal. The scheduled entity then maintains the V2X communication by performing a timing adjustment based on the packet timing information.
