  • Publication number: 20230061762
    Abstract: A polar plate is fabricated. The polar plate is flexible and made of a plastic graphite composite. No matter a supporting member is used for calendering or not, a thin polar plate with controllable thickness is fabricated. The polar plate is excellent in blocking the through-transmission of vanadium ions and the limit of blending ratio of conductive carbon is broken through. The longitudinal through-transmission volume resistivity (proportional resistance to thickness) is greatly improved by adjusting the blending ratio of conductive carbon for meeting the demand of conductivity. In the mean time, the present invention strengthens the rigidity required for the thin polar plate while providing large-area polar plate fabrication for industrial use and convenience and provides a cooling and pressing method for patterning a composite polar plate. An integrated mold is thus obtained to replace the conventional polar plate which needs to be processed and prepared with runner.

  • Patent number: 11592912
    Abstract: Clickpad structures may be attached to surfaces of an information handling system using material stacks comprising an elastic material, such as a sponge, which can preload a force on the clickpad surface. The preloaded force reduces a gap between the clickpad switch and contact point, which reduces instability, rattling, and other negative experiences with the clickpad surface experienced by a user. According to an embodiment, an input device for an information handling system includes a clickpad surface having a first side configured to receive user input and a second side opposite the first side; a first coupling stack comprising a first elastic material with a first thickness; and a second coupling stack comprising a second elastic material with a second thickness, wherein each of the coupling stacks is attached to the clickpad surface and a surface of the information handling system by adhesives.

  • Patent number: 11592890
    Abstract: Embodiments of a system, method, and memory storage device for managing performance optimization of applications executed by an Information Handling System (IHS) are described. In an illustrative, non-limiting embodiment, an IHS may include computer-executable instructions to receive telemetry data associated with an operating behavior of the IHS. Using the telemetry data, the IHS generates a profile recommendation from the received telemetry data using a machine learning (ML) service, and adjusts a core stall management mechanism of a second processor to optimize a performance of the IHS. The second processor performs at least a portion of the operating behavior of the IHS.

  • Patent number: 11563966
    Abstract: Inferring an illumination compensation flag during encoding or decoding of a video image signal using frame rate up conversion can save one bit and eliminate complexity. The illumination compensation flag can be derived from the corresponding flags of at least one bi-predictive or bi-directional prediction candidates. The flag can also be derived from some function of the flags from those candidates. Alternatively, several flags can be used for respective coding or decoding of blocks if there are more than one prediction candidate using illumination compensation.

  • Publication number: 20230007257
    Abstract: Quantization matrix can be used to adjust quantization of transform coefficients at different frequencies. In one embodiment, a single fixed parametric model, such as a polynomial is used to represent a quantization matrix. Modulation of bit cost and complexity is achieved by specifying only the n first polynomial coefficients, the remaining ones being implicitly set to zero or other default values. One form of the single fixed polynomial is a fully developed polynomial in (x,y), where x,y indicate the coordinates of a given coefficient in a quantization matrix, with terms ordered by increasing exponent. Since higher exponents are the last ones, reducing the number of polynomial coefficients reduces the degree of the polynomial, hence its complexity. The polynomial coefficients can be symmetrical in x and y, and thus reducing the number of polynomial coefficients that need to be signaled in the bitstream.

  • Publication number: 20220353846
    Abstract: A receive (Rx) UE performs blind detection to decode a first-stage Sidelink Control Information (SCI) in a received signal. The first-stage SCI contains control information for the Rx UE to locate time-and-frequency resources used by a transmit (Tx) UE. The time-and-frequency resources are used to transmit the first-stage SCI and a second-stage SCI via a Physical Sidelink Control Channel (PSCCH) and to transmit data via a Physical Sidelink Shared Channel (PSSCH) associated with the PSCCH. The Rx UE locates the second-stage SCI in the time-and-frequency resources based on the first-stage SCI. The second-stage SCI contains additional control information from the Tx UE to the Rx UE for the sidelink V2X communication. The Rx UE decodes the second-stage SCI using at least in part an identifier which identifies the Rx UE as a destination of the received signal.

  • Publication number: 20220337983
    Abstract: For sidelink vehicle-to-everything (V2X) transmission, a first user equipment (UE) obtains time-and-frequency resources that are bounded by two subchannel boundaries and two slot boundaries. The first UE transmits encoded control information to a second UE in a Physical Sidelink Control Channel (PSCCH) that occupies a first portion of the time-and-frequency resources starting from a lowest resource block (RB) in a lowest subchannel and from an earliest symbol available for sidelink control and data transmission. The first UE further transmits encoded data to the second UE in a Physical Sidelink Shared Channel (PSSCH) that occupies a second portion of the time-frequency resources. The second portion includes (a) a first set of RBs in the same symbols as the PSCCH and not used by the PSCCH, and (b) a second set of RBs in symbols not used by the PSCCH.
