  • Patent number: 12368459
    Abstract: One or more aspects of the techniques and models described herein provide for bidirectional recurrent neural network (BiRNN)-based digital pre-distortion techniques for radio frequency (RF) power amplifiers (PAs). As an example, a digital pre-distorter (DPD) system may implement residual learning and long short-term memory (LSTM) projection layer features to reduce computational complexity and memory requirements. Implementing the described unconventional techniques of applying residual learning in RNN (e.g., in BiLSTM), using LSTM projection to develop a DPD structure, or both, may provide several advantages over preexisting techniques. For instance, the complexity in training and pre-distortion may be reduced and significantly less memory may be required to store the DPD neural network coefficients (e.g., while achieving similar or better linearization performance compared to other LSTM models). Further, faster training convergence speed may be achieved (e.g., compared to other LSTM models).

  • Patent number: 12365743
    Abstract: Provided herein are novel anti-CD28× anti-PSMA antibodies and methods of using such antibodies for the treatment of PSMA-associated cancers. Subject anti-CD28× anti-PSMA antibodies are capable of agonistically binding to CD28 costimulatory molecules on T cells and PSMA on tumor cells. Thus, such antibodies selectively enhance anti-tumor activity at tumor sites while minimizing peripheral toxicity. The subject antibodies provided herein are particularly useful in combination with other anti-cancer therapies (e.g., anti-CD3× anti-PSMA antibodies) for the treatment of prostate cancers.

  • Patent number: 12369206
    Abstract: This application discloses a Bluetooth connection method, and relates to the field of short-range wireless communications technologies. The method includes: A terminal sends a service inquiry request to a Bluetooth device after the terminal and the Bluetooth device establish an asynchronous connectionless ACL link. The service inquiry request includes information about a service supported by the terminal. The Bluetooth device sends a service inquiry response to the terminal in response to the service inquiry request. The service inquiry response includes information about a service supported by the Bluetooth device. The terminal performs pairing with the Bluetooth device after the terminal receives the service inquiry response sent by the Bluetooth device. The terminal establishes a connection based on a first service to the Bluetooth device when both the terminal and the Bluetooth device support the first service. This reduces a period of time for establishing a Bluetooth service connection.

  • Publication number: 20250232014
    Abstract: Methods and systems are presented for bot detection. A movement of a pointing device is tracked via a graphical user interface (GUI) of an application executable at a user device. Movement data associated with different locations of the pointing device within the GUI is obtained. The movement data is mapped to functional areas corresponding to a range of the different locations of the pointing device within the GUI over consecutive time intervals. At least one vector representing a sequence of movements for at least one trajectory of the pointing device through one or more of the functional areas and a duration the pointing device stays within each functional area is generated. At least one trained machine learning model is used to determine whether the sequence of movements of the pointing device was produced through human interaction with the pointing device by an actual user of the user device.
