  • Patent number: 11641269
    Abstract: A method for implementing a fast UBDM transform includes receiving a first, input vector via a processor, and partitioning the first vector to produce a magnitude vector and a sign vector. A second vector, including a modified magnitude vector and a modified sign vector, is generated by: applying a permutation to the magnitude vector to produce the modified magnitude vector, converting the sign vector, based on an algorithm, into an intermediate sign vector, and applying nonlinear layers to the intermediate sign vector. Each nonlinear layer includes a permutation, an S-box transformation, a diffusive linear operation and/or an Xor operation. Multiple linear layers are applied to the second vector to produce a third vector, the third vector being a transformed version of the first vector. A first signal representing the third vector is sent to at least one transmitter for transmission of a second signal representing the transformed data vector.

  • Patent number: 11611361
    Abstract: A feed line connects an RFIC and a radiating element. A baseband ground plane (BB ground) is connected to a ground terminal of a BBIC. A radio frequency ground plane (RF ground) is placed in such a manner as to overlap the BB ground. The RF ground serves as a return path of the feed line. A first inter-ground connection circuit connects the BB ground and the RF ground. Furthermore, a second inter-ground connection circuit connects the BB ground and the RF ground. Connecting parts between these grounds and the second inter-ground connection circuit are arranged closer to the edges of these grounds than connecting parts between these grounds and the first inter-ground connection circuit. The connecting part between the ground and the second inter-ground connection circuit is placed on one side of a certain imaginary straight line that passes substantially the geometric center of the ground.

The network element management system may receiving impaired operation reports from a cable modem termination system (CMTS), and send an un-alteration request to the configurable coaxial tap. The un-alteration request may cause the configurable coaxial tap to undo the alterations to the characteristics of the configurable coaxial tap or to undo the manipulated RF characteristics of the CPE. The network element management system may receive and use information the CMTS to determine modem-tap-port correlations and the physical location of the CPE.

  • Patent number: 11496341
    Abstract: Examples described herein include methods, devices, and systems which may compensate input data for I/Q imbalance or noise related thereto to generate compensated input data. In doing such the above compensation, during an uplink transmission time interval (TTI), a switch path is activated to provide converted input data to a receiver stage including a recurrent neural network (RNN). The RNN may calculate an error representative of the noise based partly on the input signal to be transmitted and a feedback signal to generate filter coefficient data associated with the I/Q imbalance. The feedback signal is provided, after processing through the receiver, to the RNN. During an uplink TTI, the converted input data may also be transmitted as the RF wireless transmission via an RF antenna. During a downlink TTI, the switch path may be deactivated and the receiver stage may receive an additional RF wireless transmission to be processed in the receiver stage.

  • Patent number: 11212394
    Abstract: The transmit power level of a transceiver coupled to a digital subscriber line (DSL) line is reduced from a first transmit power level sufficient for the transceiver to transmit data on the DSL line at a first bit rate to a second transmit power level below the first transmit power level sufficient for the transceiver to transmit data on the DSL line at a second bit rate that is lower than the first bit rate. The reduction in transmit power is limited so that the change does not induce time-varying crosstalk sufficient to destabilize a nearby DSL line. While the transmit power level of the transceiver is reduced to the second transmit power level, the transceiver is suspended from transmitting data on the DSL line for repeated periods of time. Suspending the data transmission is controlled to avoid further time-varying crosstalk sufficient to destabilize the nearby DSL line.

  • Patent number: 11193963
    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for monitoring energy consumption. In one aspect, a method includes sending, to a power monitor of a circuit board, requests for power consumption data. The requests are sent periodically based on a reference clock that is located external to the circuit board and that is more accurate than a clock of the power monitor. Each request is for an accumulated amount of power for components of the circuit board. In response to each request, power consumption data is received from the power monitor. The power consumption data specifies the accumulated amount of power for the components of the circuit board since a previous request sent to the circuit board. An amount of energy consumed by the components of the circuit board over a time period is determined based on the received power measurements and the time period.

  • Patent number: 11129248
    Abstract: A method and apparatus for an indoor horticultural system that utilizes both a wireless and a wired network to control lighting. The wireless interface is used in a primary mode of operation to control all aspects of lighting including intensity, spectrum and color temperature. The wired interface is used in a secondary mode of operation, whereby an analog signal is used to control the intensity of all LED arrays in each lighting fixture and a digital signal is used to control the intensity of each individual LED array in each lighting fixture. Both the analog and digital signals utilize the same physical interface.

  • Patent number: 11121545
    Abstract: A hot swapping protection device for Power over Ethernet which has a state setting switch group, an interface circuit, a power supply device, a packet switching controller, multiple isolation coil sets, and multiple connectors. The packet switching controller receives a digital state value P2 of the interface circuit and a digital signal P1 of the state setting switch group and bitwise compares P1 and P2 so as to output a command to control the DC voltage outputs of the power supply device. The power supply device has a digital power controller and an analog power controller having multiple voltage output terminals for providing DC voltages to the multiple connectors. Before removing a cable connected to a connector, all voltage output states of the voltage output terminals corresponding to the connector are set to a cutoff state, so that sparks generation can be avoided during subsequent cable plug-in and unplugging.
