Three-dimensional (3D) maps may be generated for different areas based on scans of the areas using sensor(s) of a mobile computing device. During each scan, locations of the mobile computing device can be measured relative to a fixed-positioned smart device using ultra-wideband communication (UWB). The 3D maps for the areas may be registered to the fixed position (i.e., anchor position) of the smart device based on the location measurements acquired during the scan so that the 3D maps can be merged into a combined 3D map. The combined (i.e., merged) 3D map may then be used to facilitate location-specific operation of the mobile computing device or other smart device.

A tire management apparatus includes a remaining tread amount acquisition unit configured to acquire a remaining tread amount of tires, a traveling information acquisition unit configured to acquire traveling information of moving objects to which the tires are attached, a replacement time calculation unit configured to calculate a replacement time of the tires in accordance with the remaining tread amount and the traveling information, and a notification unit configured to notify a particular notification target of information on the number of the tires to be replaced at the replacement time when the number exceeds a threshold.

Disclosed herein, in one aspect, is a system for determining depth within a borehole. The system can comprise a downhole device comprising at least one inertial sensor, at least one processor, and a memory in communication with the at least one processor. The memory can comprise instructions thereon that, when executed, cause the processor to: receive data from the at least one inertial sensor and store the data from the at least one inertial sensor in the memory with respective correlated time values. The system can further comprise a drill rig comprising at least one depth measurement device. The at least one depth measurement device can comprises a drill string position sensor that is configured to produce a measurement indicative of a length of a portion of a drill string removed from a borehole or a wireline sensor that is configured to determine a length of deployed wireline cable.

Disclosed herein are vehicle mounted grinding machines adaptable to ground contours. Embodiments relate to a grinding machine with a vehicle mount configured to attach a housing body, including a grinding drum to a vehicle. One embodiment of the disclosure relates a pair of guides on opposing sides of a blade set of a grinding drum, where each of the pair of guides is horizontally aligned with the grinding drum. In another embodiment, the housing body is configured to roll about a travel direction relative to the vehicle mount. In another embodiment, the grinding machine includes an alignment motor configured to laterally translate the housing body relative to the vehicle mount and perpendicular to a travel direction.
