  • Publication number: 20240171170
    Abstract: A common gate resistor bypass arrangement for a stacked arrangement of FET switches, the arrangement including a series combination of an nMOS transistor and a pMOS transistor connected across a common gate resistor. During at least a transition portion of the transition state of the stacked arrangement of FET switches, the nMOS transistor and the pMOS transistor are both in an ON state and bypass the common gate resistor. On the other hand, during at least a steady state portion of the ON steady state and the OFF steady state of the stacked arrangement of FET switches, one of the nMOS transistor and the pMOS transistor is in an OFF state and the other of the nMOS transistor and the pMOS transistor is in an ON state, thus not bypassing the common gate resistor.

  • Publication number: 20240169253
    Abstract: Using a first dataset of labeled data, a model is trained by adjusting a feature extractor parameter, a classifier parameter, and a discriminator parameter of the model. Using the discriminator parameter and a parametric function of the feature extractor parameter, a plurality of samples of a dataset of unlabeled data is scored. A subset of the scored plurality of samples is selected for labeling. Responsive to receiving a label of each of the selected subset of the scored plurality of samples, the first dataset of labeled data is augmented with the selected subset of the scored plurality of samples and the label of each of the selected subset of the scored plurality of samples. Using the augmented dataset of labeled data, the model is retrained. The retraining comprises further adjusting the feature extractor parameter, the classifier parameter, and the discriminator parameter of the model.

  • Publication number: 20240170118
    Abstract: The present disclosure is for a system and a method for evaluating cognitive performance capabilities as a function of emotional intelligence. The present invention provides a way to more accurately and objectively assess an individual's true emotional intelligence by adjusting an individual's self-reported and often biased personality assessment by accounting for lifestyle factors and cognitive task performance factors indicative of an individual's true emotional intelligence. The adjusted emotional intelligence aids in better evaluating an individual's or team's productivity capacity allowing for better planning and allocation of tasks to improve overall productivity and may serve to reduce burnout.

  • Patent number: 11990195
    Abstract: Memory devices, systems including memory devices, and methods of operating memory devices are described, in which memory device are configured to add variable delays to a command. The variable delays may be provided by a host device (e.g., a test equipment) using a test mode of the memory devices. Alternatively, the variable delays may be stored in nonvolatile memory (NVM) components of the memory devices. Further, mode registers of the memory devices may be set to indicate that the command is associated with the variable delays stored in the NVM components. Further, the memory devices may include delay components configured to add the variable delays to the command. Such variable delays facilitate staggered execution of the command across multiple memory devices so as to avoid (or mitigate) issues related to an instantaneous, large amount of current drawn from a power supply connected to the memory devices.

  • Patent number: 11991401
    Abstract: A method for searching an AD insertion position includes following steps: S1. identifying a human body area in a video image; S2. identifying a blank wall area in the video image; and S3. determining the AD insertion position in the blank wall area in the video image, so that the AD insertion position intersects the human body area. A method for automatically inserting an advertisement AD in a video includes following steps: determining an AD insertion position in the video by searching a product AD insertion position based on deep learning, and inserting the AD on the position. Through the method, an appropriate position for an AD can be automatically searched on a blank wall part in the video. In addition, the inserted AD can be presented in the video in a natural way, and thereby avoiding or reducing the impact of AD insertion on impression of the video.
