An object sensing device has a radiation part that radiates an exploring wave forward, a sensing part having a first sensing element and a second sensing element, wherein the first sensing element and the second sensing element sense a reflected wave of the exploring wave radiated by the radiation part; and a determination part. Further, each computing unit is equipped, such that if its integrity is determined to have been compromised, the computing unit automatically takes itself out of service. This bridging is preferably done using an inter-NI link that is dedicated for communication between two or more NIs in the multi-Ni platform. The old I-MRU members are evicted, such that all the members of a congruence class may be used for data.
