Time synchronization of multi-modality measurements
First Claim
1. A method comprising:
- providing a reference signal to a translation circuit;
generating, by the translation circuit based on the reference signal, (i) a first synchronization signal capable of exciting a first emitter to produce a first wave in a first modality and (ii) a second synchronization signal capable of exciting a second emitter to produce a second wave in a second modality, wherein a modality is a domain within a form of energy, and wherein the first modality is different from the second modality; and
producing, by the first emitter, the first wave in the first modality and, by the second emitter, the second wave in the second modality, wherein the first wave is substantially directed toward a first physiological sensor configured to receive the first wave and to associate a first sensed physiological parameter with a received portion of the first wave, and wherein the second wave is substantially directed toward a second physiological sensor configured to receive the second wave and to associate a second sensed physiological parameter with a received portion of the second wave.

Abstract
The present disclosure is directed to waveform synchronization in multi-modal sensor networks. An example method includes providing a reference signal to a translation circuit. The method also includes generating, by the translation circuit, (i) a first synchronization signal capable of exciting a first emitter to produce a first wave in a first modality and (ii) a second synchronization signal capable of exciting a second emitter to produce a second wave in a second modality, wherein a modality is a domain within a form of energy. The method further includes producing, by the first emitter, first wave in the first modality and, by the second emitter, the second wave in the second modality, wherein the first wave is substantially directed toward a first sensor capable of interacting with the first wave, and wherein the second wave substantially directed toward a second sensor capable of interacting with the second wave.
