Abstract: According to examples, a system for determining a location using a plurality of geo-location techniques is described. The system may include a processor and a memory storing instructions. The processor, when executing the instructions, may cause the system to receive sensor data associated with the location, receive image information associated with the location, analyze the image information associated with the location, and provide a localization and mapping analysis for the location. The processor, when executing the instructions, may then determine an analyzed list of features and a primary landmark associated with the location, and determine location information for the location based on the analyzed list of features and the primary landmark.

Abstract: According to examples, a charging interface for a wearable device may include a receiver coil arranged inside the wearable device; a transmitter coil arranged outside the wearable device, where the transmitter coil is to generate a charging voltage for the wearable device via magnetic induction with the receiver coil. The charging interface may include a first pair of magnets having respective polarity axes and positioned at top and bottom portions of the transmitter coil, and a second pair of magnets having respective polarity axes and positioned at top and bottom portions of the receiver coil. The polarity axes to may be aligned with an attachment plane between the transmitter coil and the receiver coil. Furthermore, the polarity axes of the first pair of magnets may be reversed with respect to corresponding second pair of magnets.
