Where a mobile computer device having a position sensor, such as a GPS sensor, and an accelerometer is configured to estimate a geographic position of the mobile computer device using the position sensor, the accuracy of such positions may be enhanced by correlating accelerations of the mobile computer device, as determined by the accelerometer, against the positions of known surface features within a vicinity of the estimated positions. If the observed accelerations are consistent with one of the known surface features, the location of the mobile computer device may be correlated with the location of the one of the known surface features.

Enhancing geocoding accuracy

This disclosure is directed to controlling operation of a deployed device to selectively initiate different operational modes, which may include an employee mode, a customer mode, and/or a secure mode. While operating in the employee mode and/or customer mode, the deployed device may enable some access to information specified for the respective user while restricting some nonessential information. While operating in the secure mode, the device may restrict access to at least some information, at least temporarily. In some embodiments, the secure mode may require credentials, a decryption key, and/or other security information to enable continued use of the deployed device by the employee or possibly by the customer. The selection of the operational mode may be based at least in part on a deviation of the device's location from a predetermined route.
