| New wearable Sequential Wave Imprinting Machines (SWIMs) based on Steve Mann's invention, have been designed, built and used as augmediated reality oscilloscopes, to teach concepts of wavelength measurement in real-time and real-space in an immersive and convincing way, by means of phenomenological augmented reality.;Several new SWIM devices are reported on, which are made to meet objectives of wearability, high luminosity and high resolution. Presented are a wrist-worn SWIM device, as well as a ring-worn SWIM device.;A new modular wearable lock-in-amplifier is presented, which completes a wearable SWIM system allowing for visualization of soundwaves in nearly any setting desired.;A systems level analogy is realized between the concepts of the lock-in-amplifier, and of power measurement.;The idea of an electrical efficiency meter is explored and a combination efficiency meter/lock-in-amplifier has been designed and built which has several advantages over existing power analyzers which are reported on. |
