A bearing device to hold a rotor in an opening formed in a frame is provided. The method and apparatus is provided for identifying selected inputs of a device by a user of the device before the selected input is accepted as input for further processing in the device. A terminal monitors the control channel based on the blind decoding area information. An inference engine applies the semantic constraints to the semantic representations to determine inconsistencies between one CBM map and another and between a CBM map and the component business model meta-model. Preferably, rotating and oscillating light signals are produced by sequentially illuminating columns of LED’s on a stationary light support.
