Systems, methods, and computer code products for monitoring the behavior, health, andor characteristics of an animal are disclosed herein. The rotor blade has a tag such as an RFID tag fixed on the rotor blade at a predetermined angular position about the longitudinal axis of the rotor blade; and a sensor is fixed on the hub for contactless sensing of the tag when the tag is in a predetermined angular position about the longitudinal axis of the rotor blade. The wavelength conversion device includes a first wavelength conversion area and a polarization conversion area. Also, the required mean time between failures for design, manufacturing, infant mortality, and service phase of product life cycle can be computed. The pins operatively engage with, and rise adjacent to, the elongated arm thus intersecting the swing path of the sulky about the connecting arm, limiting its arcuate movement. The single phase output voltage of the inverter is applied onto the inductive coil of the inductive heat generation mechanism provided inside the rotating roller as the exciting voltage.
