An apparatus includes a boundary module that determines if a mobile device is within a secure area. The mobile device includes a computing device capable of connecting to a wireless network. The apparatus includes a download module that downloads a latest version of a file from a secure server to the mobile device in response to the boundary module determining that the mobile device has entered the secure area. The apparatus includes a copy module that copies the file from the mobile device to the secure server in response to the boundary module determining that the mobile device has left the secure area and a deletion module that deletes the file from the mobile device in response to determining that the mobile device has left the secure area and in response to having completed copying the file from the mobile device to the secure server.

A method, medium and implementing processing system are provided in which the presence of workers in a long highway construction zone is monitored and the electronically-controlled posted speed limit is adjusted in accordance with the detected presence of workers in the immediate area. In an example, Radio Frequency Identification (RFID) scanners or readers are strategically placed in a construction or working area. Such RFID reading devices may be embedded, for example, in construction speed limit signs. The displayed speed limit is controlled by the detected proximity of construction workers wearing RFID-embedded clothing, for example, such as safety vests or helmets. The speed limit sign includes logic to display one of many possible speed limit displays based on the nearest, and/or the number of RFID signals detected in a given area. Vehicular traffic is thereby enabled to travel faster through construction zones where no workers are present and, when appropriate, traffic is slowed when workers are present within a given proximity of the RFID reading devices.

Dynamic speed limit system

A method, computer program product, and a data processing system for generating a single object file from which a plurality of per-processor architecture executables may be produced. Source code includes instructions that are associated with a plurality of processor architectures and a plurality of instruction sets each associated with one of the plurality of processor architectures. The source code is compiled into an object file that includes common text and data associated with the plurality of processor architectures and a plurality of processor-specific data and text sets. The object file may then be linked by a processor of one of the plurality of processor architectures to produce an executable that is optimized for a plurality of processor architectures.
