U.S. Patent No. 4,887,262 Kvaser CAN Pages, CAN Introduction Single-channel bus system for multi-master use with bit cell synchronization, and master station comprising a bit cell synchronization element suitable for this purpose Inventors: van Veldhuizen; Evert D. (Eindhoven, NL). Assignee: U.S. Philips Corporation (New York, NY). Abstract Messages consisting of an arbitration field followed by a data field circulate in a single-channel bus system. The stations comprise a storage element for an intended delay time between a locally formed signal transition and a resultant detectable signal transition. The stations also comprise a continuous sequencer for the successive bit cells. When a signal transition is detected, the sequencers are loaded with the position of the storage element, so that they are synchronized. In the case of a transmission operation, the delay is measured, so as to update the contents of the storage element.
