A method includes receiving a differential voltage signal at first and second inputs of a comparator and selectively providing the differential voltage signal to one of a first conversion path and a second conversion path of the comparator during a conversion phase to determine a digital value corresponding to the differential voltage signal. The first conductive lead is insulated from the substrate by an insulating film. The correlation information is transferred from a monitored thread to threads that are activated by the monitored thread and allows to reconstruct parent-child relations between different threads. The bicycle rack includes elements that assist in the raising of the pivotal portion from the vehicle receiving position into a stowed position and for lowering the pivotal portion from the stowed position to the bicycle receiving portion. In some implementation, the encoding indicator symbol is a multi-level signal where each level of the multi-level signal represents at least two bits of information indicative of, for a corresponding bus partition, whether encoding is applied to the data to be transmitted over the bus partition.
