Abstract: A system, method and computer program product for storing configuration data for use in configuring a device while a program utilizing the configuration data is undergoing a revision at the device. The method includes a first step of providing a data structure indicating a manner in which configuration data is to be stored, and storing the data structure and current configuration data according to the data structure. Then, a revised software program in the device may identify the data structure and access a particular configuration data, along with its format; and, apply a conversion function that translates the stored current configuration data to a format compatible for use by the revised software. This is accomplished in a manner such that no configuration data is corrupted. The data structure includes data self describing the stored current configuration data, such that a conversion function can easily access the self describing information and render the stored configuration data platform independent.

Abstract: A construction machine capable of increasing a frictional force and an acceleration performance without causing unwanted slip and an excessive load to a transmission by a driving force. The construction machine comprises a first mode to set the maximum output of an engine to a prescribed output, a second mode to limit the maximum output of the engine to an output lower than the prescribed output and a mode selector switch used for a operator to select from the plurality of modes. The construction machine also comprises control means that controls the machine to operate in the second mode regardless of the mode selected by the mode selector switch when a vehicle speed is equal to or less than a prescribed speed and the opening of an accelerator is equal to or more than a prescribed opening.
