  • Patent number: 10736188
    Abstract: A power supply is electrically connected between a pair of input terminals and is configured to be supplied with electric power from an AC power supply to generate control electric power. A voltage detector is configured to detect a voltage of the control electric power. A controller is configured to be supplied with the control electric power from the power supply to operate. The controller is configured to control a bidirectional switch based on a detection signal from a phase detector so as to switch the bidirectional switch from an ON state to an OFF state at a switching time point when a variable time corresponding to a dimming level elapses from a starting point of a half period of an AC voltage. A stopper is configured to halt generation of the control electric power by the power supply when the voltage detected by the voltage detector is higher than or equal to a prescribed threshold during an OFF time period from the switching time point to an end time point of the half period.

The encoding includes selectively reducing a power of the unmodulated sinusoidal waveform at the selected phase angles in accordance with bit values of the input digital data so as to respectively define first, second, third and fourth data notches in the modulated sinusoidal waveform. An encoded analog waveform is then generated from a digital representation of the modulated sinusoidal waveform. The encoding is performed so that energies associated with the first and third data notches are balanced and energies associated with second and fourth data notches are also balanced. Each of the energies corresponds to a cumulative power difference between a power of the unmodulated sinusoidal waveform and a power of the modulated sinusoidal waveform over a phase angle range subtended by one of the data notches.

  • Patent number: 10568082
    Abstract: Various embodiments disclosed herein provide for reduced overhead signaling when a user equipment device is being configured with multiple bandwidth parts for downlink transmission. When a user equipment device is being configured with multiple bandwidth parts (channels on an aggregate carrier), the signaling that indicates the codebook subset restriction bit map, rank restriction bit map, and beam restriction bit map needs to be repeated for each bandwidth part. Often however, the restriction bit maps are repeated in the bandwidth parts, and so overhead can be reduced by encoding a confirmation bit in each bandwidth part, such that if the confirmation bit is set to “1”, the user equipment device can know to apply the restriction bit map from the primary bandwidth part to the secondary bandwidth part, without having to encode the secondary bandwidth part restriction bit map.

  • Patent number: 10511356
    Abstract: A multi-antenna network system has a reduced operational complexity for matrix inversion by referring to the variations of the status of a plurality of communication channels at a first time duration and a second time duration. Therefore, the speed for calculating matrix inversion is improved. Accordingly, the amount of servo antennas and/or user antennas operating in the same multi-antenna network system can be increased.

  • Patent number: 10491365
    Abstract: Apparatus(es) and method(s) for CDR are described. In a CDR circuit, there is a bang-bang phase detector (“BBPD”), a baud-rate phase detector (“BRPD”), a multiplexer, and a control circuit. The BBPD, configured to receive data and crossing samples, generates a first result indicating a first phase difference between data and crossing samples. The BRPD, configured to receive data and peak samples, generates a second result indicating a second phase difference between data and peak samples. The multiplexer is configured to select either such result as a phase-detect output for a mode of operation. A control circuit is configured to clear a metastable state: for receipt of the first detect result, check for dithering, determine a direction for phase adjustment responsive to detection of the dithering, and provide a phase adjustment in the direction; and for receipt of the second detect result, operate to use the second phase difference generated.

    Abstract: Novel tools and techniques are provided for implementing network timing functionality. In some embodiments, a grand master clock(s) might receive a first timing signal from a global positioning system (“GPS”) source via a GPS antenna(s), and might send a second timing signal (which might be based at least in part on the first timing signal) to a slave clock(s), in some cases, via one or more network elements or the like. A computing system might calculate various transmission times for the second timing signal to be transmitted between the grand master clock(s) and the slave clock(s), and might calculate any time delay differences in the transmission times, might generate a third timing signal based at least in part on the calculated time delay differences (if any), and might send the third timing signal to one or more network elements, thereby providing Accurate Synchronization as a Service (“ASaaS”) functionality.
