Apparatuses and methods may include receiving a power-down command at a first subsystem comprising a first processor, a first volatile memory, a first nonvolatile memory, a first compressordecompressor, and a first power control circuit, the first volatile memory being configured to store state data relating to operating conditions of the first subsystem. A connecting element connects the damping mass to the coupling body. 5 KHz to about 100 KHz may be applied to the patient’s spinal cord region to address pelvic pain without creating paresthesia in the patient. The address database may store the network address accessed by the first access device. Data management work for individually managing the noncircular part shape data and the other condition data is not necessary, those data can be collectively managed, and the relevant data can be collectively entered. The drain wire is disposed over one of the conductors and may be conductively coupled to the conductor via use of a single contact of an insulation displacement connector that engages both the drain wire and the respective conductor.
