Carbon foam liberates lead-acid batteries for emerging military missions
The limitations of conventional lead-acid batteries lie in the electrodes, and a fundamental breakthrough replacing lead with carbon-graphite foam allows the true potential of this mature battery chemistry to be more fully harnessed while maintaining conventional form factors for military equipment....
Microwave/Millimeter-Wave Components
Micro-miniature connectors A micro-miniature connector family from Hypertronics, the HyperGrid series, targets high-reliability connections in high-density...
Characterizing phase-locked loops with waveform scans
Identifying frequency stability problems within a phase-locked loop design can be greatly simplified when using an automated method. When an oscilloscope detects the period of a waveform cycle, this value can be directly inverted to compute the instantaneous frequency of the specific waveform cycle. ...
