  • Publication number: 20250038865
    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.

  • Publication number: 20240364314
    Abstract: In some embodiments, an apparatus includes an antenna; a radio-frequency (RF) tuning network configured to receive an input signal via the antenna; an RF energy harvester operatively coupled to the RF tuning network and configured to produce a direct current (DC) output based on the received output of the RF tuning network; and a load manipulator configured to be transitioned between a first configuration and a second configuration to manipulate one or more properties associated with the RF energy harvester such that an input impedance of the RF energy harvester changes from a first input impedance to a second input impedance. The first input impedance is associated with a first distribution of RF energy associated with the input signal relative to the RF energy harvester and the second input impedance is associated with a second distribution of RF energy associated with the input signal relative to the RF energy harvester.

  • Publication number: 20240364137
    Abstract: In some embodiments, an apparatus includes an antenna and a rectifier operatively coupled to the antenna and configured to receive an input power via the antenna. The rectifier can include a plurality of stages, each stage of the plurality of stages including a tuning network including one or more lumped elements. An initial stage can be configured to receive the input power and produce a power based on the input power. Each stage of the plurality of stages coupled to the antenna via at least one previous stage can be configured to receive a power from the previous stage and to produce a subsequent power associated with (e.g., based on) the power received from the previous stage. The rectifier can be configured to output a power associated with a direct current (DC) voltage having a voltage level based on a voltage level associated with the input power.
