Patent GB-2341465-A (GB)
Title: Determining the actual class of an object at run time
Inventor: BALL MICHAEL S
IPC: G06F9/44
Filed: 1999-05-18
Abstract: A dynamic down cast or cross cast 700 is performed at run time within an object-oriented programming language such as C + +. The compiler generates data structures (200 Figure 4) during a compile; at run time a routine in the language support library accesses the generated data structures in order to perform the dynamic cast. Class structure information is provided in a size that varies linearly as the total number of classes in the class hierarchy. Cryptographic hashing of class names is used to provide uniqueness. The dynamic cast addresses complications in C + + due to "virtual" and "nonvirtual" inheritance. A run time type identification (RTTI) data structure (216) is created at compile time. An offset (218) within an object description (204) is calculated for each sub-object (206) of the object. Those virtual base classes that are duplicates are skipped producing a data structure that may be searched linearly as the number of classes in the hierarchy. An identifier (248) for each sub-object is stored in the data structure with its offset (250). Each virtual table (214) also stores the offset (218) of its corresponding sub-object. The static type object pointer is used to access the object (204) through a particular sub-object. The virtual table associated with the sub-object is used to access the data structure, which is searched for the target type (248), and its associated offset is combined with the offset (218) from the virtual table to adjust the object pointer to cast it to the target type.

Patent HU-T69607-A (HU)
Title: System for termite detection and control
Inventor: THORNE BARBARA L
IPC: A01M1/20
Filed: 1993-09-07
Abstract: A system for termite detection and control is provided by a subterranean bait station having a perforated outer housing permanently implanted in the terrain below ground level, and a perforated cartridge removably received within the housing. The openings in the housing and the cartridge are in alignment with each other when the cartridge is fully received within the housing in its operational position. The cartridge received within the housing will initially contain a non-toxic bait material for diagnosing or assessing the level of a termite infestation; the bait cartridge is periodically removed from the housing to inspect for termite activity. If termite activity is detected, the non-toxic bait cartridge is replaced in the housing with a correspondingly perforated pesticide-containing bait cartridge for extermination of termites. Removal, replacement and substitution of the non-toxic and pesticide containing cartridges does not disturb pre-existing termite foraging galleries as a result of the precise alignment of the openings of the housing and the removable, exchangeable cartridges. The system may also be used for above-ground termite detection and control by externally mounting an appropriately modified housing to an outer surface of any article to be monitored, such as a timber.

Title: Method and apparatus for propelling and retarding off-road haulers
IPC: B60L50/15
Filed: 1990-11-26
Abstract: An improved method and apparatus for powering and controlling the operation of large diesel-electric off-road haulers of the type in which hauler drive wheels are propelled and retarded by DC electric wheel motors powered from on-board generators, optionally supplemented by DC power, from external trolley lines. In the disclosed system, thyristor-type converters connected into the system AC power grid are used to receive supplemental external power from DC trolley lines and supply it into the AC power distribution grid in the propel mode. The use of such thyristor-type converters makes possible the use of supplemental trolley line power without provision of separate switching or control gear to operate the DC wheel motors when trolley line power is received. Thyristor-type converters also may be used to supply current generated by wheel motors in the retarding mode to retarding resistors, making possible the use of the initial electrical power generated by the wheel motors to replace load requirements of the diesel engine, resulting in substantial fuel savings.
