  • Publication number: 20250007600
    Abstract: Techniques are disclosed to address issues related to the computation of channel state information (CSI) and angular spectrum (AS) to perform beamforming. The CSI and AS, as well as various statistical channel parameters of a wireless channel, may be computed using different techniques, which include the use of domain knowledge enhanced neural networks (DKE-NNs). The CSI and AS may be further utilized to perform beamforming using various techniques. One of these techniques may include the implementation of eigen beamforming, which provides artificially generated power at locations within the AS that are identified with estimated eigenvector beam locations. As a result of the artificially-generated power, the resulting vector decomposition used to provide the beamforming weights results in widened eigenvector beams.

  • Patent number: 12176745
    Abstract: A forced discharge test apparatus includes a heating circuit; a discharge circuit; a temperature sensor; and a controller. When the controller receives a test command indicating a test resistance and a test temperature, the controller outputs a first control signal to the heating circuit to increase the temperature of a battery cell. The controller outputs a second control signal to the discharge circuit to discharge the battery cell when the temperature of the battery cell reaches the set test temperature. The controller determines that the test temperature is valid with respect to the test resistance when the temperature of the battery cell is equal to or lower than the upper temperature limit at a time point at which a predetermined heating time has passed from a time point when the first control signal is outputted.
