A female self-administrable topical therapy device is disclosed which can be self administered by women to collect specimens from the vaginal cavity andor apply topical treatment therapy therein. The modular stanchions are selectively positionable along x and y axes relative to a top surface of the pallet base. In one embodiment, the estimated measurement false alarm probabilities are combined to determine the reliability of the determined position solution or the reliability of the set of measurements as a collection. Such operational characteristics may include operating at increased temperatures or carrying additional electrical charge or other operational characteristics.
