Provided is a method of manufacturing a wafer lens in which the surface configuration of the lens section can be transferred with high precision. Available situations are retrieved. Each tag assigned is added to a linked list associated with the corresponding virtual channel. Filtering the carrier signals of the multicarrier transmit signal is performed by the first set of bandpass filters while the decoupling of the second set of bandpass filters limits energy in the respective frequency band. The mixing of the aggregate, prepolymer, glycol and water is conducted under conditions which entrain air in the media and do not adversely affect the growth of seedlings or plants. In one embodiment, the stator plate is configured to rotate and apply a skew condition to each of the planet axles.
