Novel haloaluminoxane compositions have been formed. The system includes an injector, a reference laser beam source, an amplifier and phase conjugater, and a combiner. A mating end of the second contact may be offset in a second direction relative to a mating end of the first contact. The control unit interrupts the erase operation of the memory cells and holds an erase condition before the interrupt in accordance with a first command during the erase operation, and resumes the erase operation based on the held erase condition in accordance with a second command. The electronic control module may control a machine based on the virtual output value responsive to determining that the trust level of the physical sensor is below the first threshold trust value.
