A new and distinct cultivar of mini Impatiens plant characterized by its small rose flowers, freely flowering habit, dark green foliage, and bushy shaped growth habit with excellent basal branching. The phase compensation data results in or comprises an adjustment to the estimated range based on a direct signal vector length of a direct path signal and a multipath-impacted signal vector length of a multipath-impacted signal that are determined through observed signals or observed signal vectors of the receiver. The user can extend the attachment means out of the channel to temporarily attach the mouthguard assembly to clothing or apparatus of the user for storage of the mouthguard when it is not used. The apparatus further includes an antenna weighting factor module coupled to the first antenna and configured to iteratively adjust the antenna weighting factor in response to the second signal.
