摘要： A computer-implemented method is provided for automatically guiding a first vehicle to maintain a position relative to a second vehicle traveling in a given area. The method includes the steps of: (a) receiving location data on the first and second vehicles; (b) determining a legal travel path in the given area from the first vehicle toward an expected position of the second vehicle; (c) automatically controlling the first vehicle to travel along the legal travel path; and (d) repeating steps (a) through (c) to automatically move the first vehicle to a relative position from the second vehicle and then to automatically maintain the relative position as the first and second vehicles travel through the given area.

摘要： A pointer representation includes a permission field to define capabilities of the system in processing the data to which an address in the pointer of representation points. Bounds of the memory segment to which the capabilities apply are defined by a block field, which defines a block size, and a length field, which defines a number of blocks of that size within the segment of memory. To permit computation of the full range of addresses to which the capability applies, a finger field is included to denote the block of the segment of memory to which the address points. An increment-only bit may cause the system to preclude any negative offsets from the address in the pointer representation. Subsegments within a segment may be further defined by additional block, length and finger fields.

摘要： Short-quasi-unique-identifiers (SQUIDs) are generated and assigned to the data objects stored in memory. Pointers to a particular data object contain the data object's assigned SQUID. If a data object is moved to a second allocated memory segment, a new pointer to the second allocated memory segment is placed at the original memory segment, so that any pointers to the original memory segment now point to the new pointer. The distribution of SQUIDs is uniform. SQUIDs can be generated by counting, generated randomly, generating through some hashing mechanism, or other means. In comparing two different pointers, it is determined that the two pointers do not reference the same data object if the SQUIDs are different. On the other hand, if the SQUIDs are identical and the address fields of the two pointers are identical, then the two pointers reference the same data object. In addition, a pointer is associated with a migration indicator field which indicates the number of migrations of the referenced data object prior to the pointer being created. The comparator determines that two pointers do not reference the same data object if their associated migration indicators indicate identical numbers of migrations and their corresponding addresses are different.
