A method and system for providing a network protocol for utility services are disclosed are disclosed. The anchoring element includes a shank to be anchored in a bone or a vertebra and a head, the head having an exterior surface with a spherical segment-shaped portion. For each pair of consecutive transitions of the specified transition type, a length between the consecutive transitions is determined. Further, the motor does not stop due to an increase in the temperature of the motor, thereby preventing an unnecessary increase in the time required to complete washing. A proximal end of the bilge surface engaging member is releasably connectable in a first use mode to the upright support member. Thus the master station and the slave station can conduct data transmission from and to each other with priority use of a communication network.
