Abstract: A system including a vessel having a wall defining a volume. The vessel may contain media. The system also includes a wireless sensing system having a plurality of sensor nodes dispersed within the media and that may measure one or more parameters or conditions within the vessel and wirelessly transmit a first data signal containing the one or more parameters/conditions, and one or more through-wall communications systems attached to the wall of the vessel and that may wirelessly communicate with the plurality of sensor nodes, to transmit a first communication signal, a first power signal, or both through the wall of the vessel, to receive the first data signal, and to transmit a second data signal through the wall of the vessel, and a control system communicatively coupled to the wireless sensing system and that may determine and profile the one or more parameters/conditions based on the second data signal.

Abstract: The present invention generally relates to carbophosphates and other compounds. Such compounds may be used in batteries and other electrochemical devices, or in other applications such as those described herein. One aspect of the invention is generally directed to carbophosphate compounds, i.e., compounds containing carbonate and phosphate ions. For example, according to one set of embodiments, the compound has a formula Ax(M)(PO4)a(CO3)b, where M comprises one or more cations. A may include one or more alkali metals, for example, lithium and/or sodium. In some cases, x is greater than about 0.1, a is between about 0.1 and about 5.1, and b is between about 0.1 and about 5.1. In certain embodiments, the compound may have a unit cell atomic arrangement that is isostructural to unit cells of the minerals sidorenkite, bonshtedtite, bradleyite, crawfordite, or ferrotychite.
