Methods and apparatuses are provided that may be implemented in various electronic devices to possibly reduce a first-time-to-fix andor otherwise increase the performance or efficiency of a device by employing a positionvelocity estimation process using at least one estimated time relationship parameter. For each redundant element, a bypass circuit is provided and has in each case a reference bit transmitter for supplying K reference bits that are programmable by selective destruction or by selective introduction of conductive links in order to set a comparison device to the identification of a selected address. In some embodiments, the data sources may be able to perform local join operations. The automatic power adjusting apparatus suppresses the effective power on a transmission line to the value smaller than the prescribed value while the automatic voltage adjusting apparatus is performing an automatic control, thereby maintaining transmission-side system voltage within a tolerant system voltage range.
