An AFM based technique has been demonstrated for performing highly localized IR spectroscopy on a sample surface. In a frequency environment where the incumbent system exists, a frequency resource management may be smoothly performed using a plurality of frequency sets classified based on a utilization state of each sub-frequency resource. When an ID is received from the second party at a money-transfer location; the verification criteria is retrieved from the host computer system; and the acceptability of the ID is determined in accordance with the verification criteria. The elastomer material is removed by peeling prior to adhesion bonding of the heat sink to the die. Therefore, speed control performance of the brushless motor is improved while avoiding the upsizing and const increase of the apparatus. The control system may include a converter circuit operatively coupled to the stator and including a plurality of switches in selective communication with each phase of the stator and a controller in communication with each of the stator and the converter circuit.
