    摘要: A memory authentication technique for field maintenance tools is provided. A non-volatile electronic memory includes a unique software identifier. A non-reversible algorithm is applied to the unique software identifier to obtain a result. The result is then encrypted and compared with a stored encrypted result previously stored on the electronic memory. Based upon this comparison, the tool can be fully enabled, fully disabled, or selectively enabled.

    摘要: A handheld field maintenance tool is provided with a removable memory module. The module is preferably adapted to be removable in the presence of a hazardous environment. Further, the handheld field maintenance tool is adapted, via hardware, software, or both to automatically detect the presence of the removable memory module and to copy, or otherwise install, data from the module to the tool. Data can be placed on a removable memory module in any suitable manner including flashing flash memory within the removable memory module, or, in embodiments where the removable memory module includes both storage and input/output capability, transmitting software and/or data to the storage media through the input/output capability.

    摘要: Improved script generation and usage for handheld field maintenance tools is provided. In one aspect, the handheld field maintenance tool actually generates scripts for later playback. Preferably script generation and/or playback or features are provided to field maintenance technicians. Additionally, scripts can be played on the handheld field maintenance tool without modification to the tool itself.
