A digital rights management system operates on a computing device and requires a black box for performing decryption and encryption functions. The stationary member includes a circumferential surface that is resiliently deformable by the forces induced by the passage of the rolling bodies when the rotary member rotates. An output signal of the at least one matching circuit is connected to the electrical medium to produce a combined signal that is representative of characteristics of the subterranean structure and in which the noise is suppressed. Then, the measurement from the temperature sensor is processed in conjunction with the transformation to establish a programming time for a memory device as a function of a programming voltage and the temperature of the memory device. As such, a hexagonal tool having a neck portion and a driving head is thus quickly formed.
