  • Patent number: 11139681
    Abstract: A smart switching panel for selectively connecting either a primary power supply or a secondary power supply to a plurality of electric loads. The switching panel includes a plurality of switching elements each connected to both the primary and secondary power supplies. A controller of the switching panel operates to cause the switching element to transition between a first position in which the primary power supply is connected to the electric load, a second position in which the secondary power supply is connected to the electric load and an open condition. A current sensor is positioned to monitor the amount of current drawn by the electric load and is connected to the controller such that the controller can monitor the amount of current drawn by each of the electric loads. The controller can transition each of the switching elements to the open condition when the current draw exceeds a current threshold.

  • Patent number: 11121582
    Abstract: The present technology is directed to a system and method for implementing passive power harvesting from ambient electromagnetic emissions with a smart rectenna that incorporates automatic frequency response tuning features. The disclosed system incorporates a tunable High Pass Filter and voltage multiplier rectifier with a front-end ultra wide band antenna unit. The frequency response of tunable components can be actively adjusted to match the frequency band containing most of the energy in the incident electromagnetic emission. A look up table is used for determining the appropriate biasing levels of the tunable components for each frequency in a frequency band of interest. By tuning a frequency response of impedance matching, filtering and rectifying components to correspond to a frequency region of maximum power spectral density in the incident energy signal, the system facilitates the scavenging of ambient electromagnetic energy from the spectral region with the highest power spectral density.

  • Patent number: 11101705
    Abstract: Timing Acquisition Module (TAM) configured for use in or associated with a WTPS and associated methods, apparatus, and systems. The TAM is configured to receive encoded beacons broadcast by wireless power receiver clients requesting power on demand. The TAM decodes the encoded beacons to identify which client broadcast the beacon and notifies the WPTS that a client is requesting power, along with an identifier of that client. In response, the WPTS transmits wireless power signals to the client to service the power request. The WPTS and client may use separate beacons or signals to command the client to broadcast its WPTS beacon, whereby phases of the beacon signal are detected by antennas in the WPTS antenna array and processed to direct the wireless power signals from the WPTS to the client. Multiple apparatus including a combination of a WPTS and TAM may be implemented in a wireless power environment in a cooperative manner, enabling a client to move within the environment while supporting power on demand.

  • Patent number: 11101686
    Abstract: In embodiments of the present invention improved capabilities are described for providing intelligent power control in response to an external power interruption, causing a processor is in an electrical fixture to interrogate an external power control switch to gain an understanding of the switch's state, where prior to the external power interruption the electrical fixture may be powered by external power and where external power may be connected and disconnected by a user of the switch. In the event that the switch's state is determined to be such that it would normally pass power to the electrical fixture, the processor causes the electrical fixture to operate using a backup power supply. In the event that the switch's state is determined to be such that it would normally not pass power to the electrical fixture, the processor causes the electrical fixture to act as if the user of the switch has intentionally removed power.
