Abstract
Techniques are described for accumulating data regarding the charging environment and power delivery efficiency at various regions in the environment under various transmission conditions. In some embodiments, this data may be utilized to generate efficient and sophisticated power transmission schedules; however, this data may also be leveraged for the manipulation of the standing waves within the environment. This allows for two discrete and powerful applications: creation of null zones and conversely the generation of high power regions. These regions may also be referred to as ‘power nulls’ and ‘energy balls’ respectively.
