  • Patent number: 12074652
    Abstract: In some embodiments, a transmitter has a first mode and a second mode. The transmitter is configured to repeatedly send discrete first wireless signals carrying transmitter identification information uniquely associated with the transmitter in the first mode and to send a second wireless signal carrying the transmitter identification information in the second mode. A receiver is configured to receive a wireless signal of the first wireless signals such that the receiver is activated by the wireless signal of the first wireless signal and, in response to receiving the wireless signal of the first wireless signals, to send a third wireless signal carrying the transmitter identification information to the transmitter. The transmitter is configured to transition from the first mode to the second mode in response to receiving the third wireless signal and determining that the third wireless signal includes the transmitter identification information uniquely associated with the transmitter.

  • Patent number: 11921527
    Abstract: An optocoupler circuit includes first and second resistors, an optocoupler, a reference circuit, and a comparator. The optocoupler includes a light source and a phototransistor. The light source is connected to form a first voltage divider with the first resistor. The phototransistor is connected to form a second voltage divider with the second resistor. The optocoupler transitions an output of the second voltage divider between first and second levels. Magnitudes of the first and second levels are greater than zero. The reference circuit is configured to output a reference voltage. The comparator includes a first input and a second input. The first input receives an output of the first voltage divider. The second input receives the reference voltage. An output of the comparator transitions between a third level and a fourth level based on a comparison between the output of the first voltage divider and the reference voltage.

  • Patent number: 11696211
    Abstract: In some embodiments, a method includes receiving, at a first wireless device of a plurality of wireless devices, a data packet including an indication of a source of the data packet. In response to the first wireless device being associated with the source of the data packet, whether the first wireless device is a local repeater can be determined based on at least one of a random number or a number of wireless devices of the plurality of wireless devices. In response to the first wireless device being determined to be a local repeater, the first wireless device can be caused to be configured as a local repeater such that the first wireless device sends the data packet to at least one remaining wireless device of the plurality of wireless devices.

  • Patent number: 11362582
    Abstract: A desired OFF period module is configured to determine a desired OFF period for a plurality of switches of a PFC circuit based on an input voltage and an output voltage. A blanking timer module is configured to output a blanking signal, set the blanking signal to a first state when a countdown timer is greater than zero, and set the blanking signal to a second state when the countdown timer reaches zero. A switching control module is configured to: transition a first switch of the plurality of switches from an ON state to an OFF state in response to (i) a measured current through an inductor of the PFC circuit being greater than a demanded current through the inductor and (ii) the blanking signal being in the second state; and maintain the first switch in the OFF state for the desired OFF period after the transition.
