  • Patent number: 11871344
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) associated with a first subscription and a second subscription may establish a connection with a base station, the first subscription in a connected state. The UE may use the first subscription to perform a communication activity with the base station while the first subscription is in the connected state. Upon completion of the communication activity, the UE may transmit UE assistance information (UAI) to the base station indicating a preference of the UE to switch the first subscription to an inactive state in response to a release message from the base station.

  • Patent number: 11861279
    Abstract: A computer-aided design (CAD) tool is provided for logic optimization and synthesis. The CAD tool executes a process that involves optimizing power, performance, and area (PPA) of a logic circuit by minimizing a number of CMOS gates, and majority and/or minority gates in the circuit and its depth. The CAD tool implements a methodology of optimizing logic synthesis based on a mix of standard cell libraries (such as AND, OR, NAND, NOR, XOR, Multiplexer, full adder, half adder, etc.) and varying input majority and minority gates (where the number of inputs in the minority and majority gates could vary as odd numbers from 3 and above). The standard cell libraries cells may contain minority and/or majority gates.

  • Patent number: 11863183
    Abstract: A new class of multiplier cells (analog or digital) is derived from a 1-bit full adder and an AND gate. The 1-bit full adder is derived from first and second majority gates. The multiplier cell can also be implemented with a combination of two majority gates with majority and AND functions integrated in each of them. The two majority gates are coupled. Each of the first and second majority logic gates comprise a capacitor with non-linear polar material. The first and second majority gates receive the two inputs A and B that are to be multiplied. Other inputs received by the first and second majority gates are carry-in input, a sum-in input, and a bias voltage. The bias voltage is a negative voltage, which produces an integrated AND function in conjunction with a majority function. The second majority gate receives additional inputs, which are inverted output of the first majority gate.

  • Patent number: 11863184
    Abstract: Asynchronous circuit elements are described. Asynchronous circuit elements include a consensus element (c-element), completion tree, and validity tree. The c-element is implemented using adjustable threshold based multi-input capacitive circuitries. The completion tree comprises a plurality of c-elements organized in a tree formation. The validity tree comprises OR gates followed by c-elements. The multi-input capacitive circuitries include capacitive structures that may comprise linear dielectric, paraelectric dielectric, or ferroelectric dielectric. The capacitors can be planar or non-planar. The capacitors may be stacked vertically to reduce footprint of the various asynchronous circuitries.

  • Patent number: 11863521
    Abstract: Automated techniques for converting network devices from a Layer 2 (L2) network into a Layer 3 (L3) network in a hierarchical manner are described herein. The network devices may be configured to boot such that their ports are in an initialization mode in which the ports are unable to transmit locally generated DHCP packets. When a network device detects that a neighbor (or “peer”) device has acquired an IP address or has been configured by a network controller, then the port on which the neighbor device is detected can then be transitioned from the initialization mode into a forwarding mode. In the forwarding mode, the port can be used to transmit packets to obtain an IP address. Thus, the network devices are converted from an L2 device to an L3 device in a hierarchical order such that upstream devices are discovered and converted into L3 devices before downstream devices.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a message from a network entity indicating a set of machine learning models, a set of parameter sets, or both and one or more usage conditions associated with the machine learning models and parameter sets. Based on a usage condition being satisfied, the UE may select a machine learning model, a parameter set, or both for generating a machine learning inference. For example, the UE may select the machine learning model or the parameter set based on a priority, whether sufficient input data is provided, or based on other usage conditions. The UE may generate the machine learning inference using the selected machine learning model or the selected parameter set, and the UE may transmit a report indicating an output of the machine learning inference to the network entity.
