Abstract: Technologies directed to calibrating phased array antennas are described. A processing device of a communication device causes a first radio to send a first signal via a first antenna element. The first signal has a set of tones. Each tone of the set of tones has a frequency within a fixed frequency range. The processing device causes a second radio to receive a second signal via a second antenna element. The second signal is a response to the first signal. The processing device determines that there is a difference between the second signal and a reference signal. The processing device adjusts at least one of a phase parameter value, a gain parameter value, or a time-delay parameter value of a radio frequency component based on the difference.

Abstract: Apparatus and associated methods relate to a neutralization and circulation module (NCM) configured to generate a combustion suppressant stream from a flammable intake stream. In an illustrative example, the NCM includes an intake port and an output port, each in fluid communication with a chamber containing (electro)chemical energy storage units capable of emitting combustible gases. The NCM may, for example, include a reactor in fluid communication between the intake and output port. The reactor may, for example, selectively apply an oxygen-containing stream from an oxygen source to the intake stream to generate, from the stream containing combustible gases, a combustion suppressant gas stream that is discharged through the output port into the chamber such that an upper flammability limit approaches a lower flammability limit in the chamber. Various embodiments may advantageously eliminate a flammable regime in a chemical energy storage environment.
