The invention provides organonitro thioether compounds, compositions containing such compounds, isolated organonitro thioether compounds and methods for using such compounds and compositions to treat cancer in a patient. In one embodiment, identical insert halves are supported in corresponding insert cavities in the bearing block sections, and a small thin clip is secured between the sections to prevent relative rotation between the insert halves and the bearing block. The monitoring module may gather and generate various identification information to be included in the registration protocol messages. The power transmitting device includes an RFID reader that reads out information from the ID tag in a contactless manner.
