  • Patent number: 11617104
    Abstract: A node in a wireless mesh network determines that a threshold level of duplicate network protocol data units (PDUs) are received. Further, the node receives one or more network PDUs comprising respective segments of transport data in a transport PDU. The node relays a subset of the received one or more network PDUs comprising respective segments to one or more neighboring nodes. The subset is relayed based on determination that the node has received a threshold level of duplicate network PDUs.

The first nitride layer is on a silicon layer. The gate stack is separated from a substrate by a first oxide layer. The gate stack is oxidized to form a polysilicon layer from the silicon layer, and to form a second oxide layer on a sidewall of the polysilicon layer. A drain region of the LDMOS transistor is implanted with a first implant aligned to a first edge formed by the second oxide layer. A second nitride layer is formed conformingly covering the second oxide layer. A nitride etch-stop layer is formed conformingly covering the second nitride layer.

  • Patent number: 11611417
    Abstract: A data unit comprising bits to transmit over one or more frequency segments in a frequency range is obtained. An effective bandwidth in each frequency segment of the frequency range is determined, where the effective bandwidth excludes bandwidth of one or more punctured subchannels in a respective frequency segment. Bits are encoded based on the effective bandwidth of each frequency segment followed by parsing the encoded bits to one or more streams and parsing the encoded bits of a stream to the one or more frequency segments. The parsing of the encoded bits of the stream comprises allocating a first number of consecutive encoded bits to a first frequency segment and allocating a second number of consecutive encoded bits to a second frequency segment, wherein the first number and the second number are based on the effective bandwidth of the first frequency segment and the second frequency segment. The encoded bits are modulated and mapped to subcarriers for transmission.

  • Patent number: 11609821
    Abstract: A fault recovery system including a fault controller is disclosed. The fault controller is coupled between a processor and an interconnect, and configured to receive a time-out signal that is indicative of a failure of the processor to execute a transaction after a fault is detected in the processor. The failure in the execution of the transaction results in queuing of the interconnect. Based on the time-out signal, the fault controller is further configured to generate and transmit a control signal to the processor to disconnect the processor from the interconnect. Further, the fault controller is configured to execute the transaction, and in turn, dequeue the interconnect. When the transaction is successfully executed, the fault controller is further configured to generate a status signal to reset the processor, thereby managing a fault recovery of the processor.

  • Patent number: 11609833
    Abstract: A self-test mechanism within an integrated circuit to test for faulty operation of a clock monitor unit implemented within the integrated circuit for monitoring a clock signal. The mechanism intentionally injects faults into the clock monitor unit to evaluate if the clock monitor unit is operating in accordance with its specified operating parameters. The injected faults are intended to cause the clock monitor unit to determine that the clock signal is operating outside of an artificially generated, imaginary specified frequency range. If the injected faults do not cause the clock monitor unit to determine that the clock signal is operating both above and below the artificially generated, imaginary specified frequency range, then the clock monitor unit is not functioning according to specified operating parameters.

  • Patent number: 11606053
    Abstract: A method for initial position detection of an electric motor includes determining a delta voltage for each of three pairs of stator windings by sequentially energizing and deenergizing each pair. The delta voltage is measured through a non-energized stator winding connected to a center tap of each respective pair. A minimum delta voltage is determined from an absolute value of a minimum of the three delta voltages. The minimum delta voltage is associated with a remaining stator winding not included in the respective pair. The two delta voltages not associated with the minimum delta voltage are compared to determine the proximity of the remaining stator winding to one of a D-axis of a rotor of the electric motor and a Q-axis of the rotor.

  • Patent number: 11604223
    Abstract: A clock control system for a scan chain generates two clock signals. During a shift phase of a testing mode of the scan chain, one clock signal is an inverted version of the other clock signal. The clock control system provides the clock signal and the inverted clock signal to two different scan flip-flops of the scan chain, respectively. Each of the two scan flip-flops performs a flip-flop operation when the received clock signal transitions from a de-asserted state to an asserted state. Thus, the two flip-flop operations are mutually exclusive during the shift phase. As a result, a dynamic voltage drop across the scan chain during the shift phase is reduced.

  • Patent number: 11605228
    Abstract: An early fusion network is provided that reduces network load and enables easier design of specialized ASIC edge processors through performing a portion of convolutional neural network layers at distributed edge and data-network processors prior to transmitting data to a centralized processor for fully-connected/deconvolutional neural networking processing. Embodiments can provide convolution and downsampling layer processing in association with the digital signal processors associated with edge sensors. Once the raw data is reduced to smaller feature maps through the convolution-downsampling process, this reduced data is transmitted to a central processor for further processing such as regression, classification, and segmentation, along with feature combination of the data from the sensors.
