There is provided a computer implemented method of computing a location of an object, comprising: accessing a wide field of view (wFOV) image captured by a wFOV image sensor located relative to an object, analyzing the wFOV image to identify a predefined feature, wherein the predefined feature indicates a low accuracy location of the object, capturing a high resolution image by a high resolution image sensor located relative to the object, the high resolution image depicting the predefined feature, and computing a high accuracy of location of the object according to an analysis of the predefined feature and according to a correlation between a location and orientation of the wFOV image sensor and the high resolution image sensor.

A personal items network, comprising a plurality of items, each item having a wireless communications port for coupling in network with every other item, each item having a processor for determining if any other item in the network is no longer linked to the item, each item having an indicator for informing a user that an item has left the network, wherein a user may locate lost items. A method for locating lost personal items, comprising: linking at least two personal items together on a network; and depositing one or both of time and location information in an unlost item when one of the items is lost out of network.

Examples relate to digital context aware (DCA) data collection. In some examples, a DCA start location component is positioned at a first location along a travel route, and a DCA end location component is positioned at a second location along the travel route. In response to using a wireless interface to detect the DCA start location component, data collection of measurements by a sensor are initiated. In response to using the wireless interface to detect the DCA end location component, the data collection by the sensor is halted.

Devices, systems and methods wherein sequential signals are emitted from a plurality of signaling modules positioned in an array which demarcates a route or boundaries to be followed by a pedestrian or vehicle.

A system for drone coordination includes logic to detect an adverse weather condition and detect a plurality of drones operating in a region to be affected by the adverse weather condition. The logic can also transmit a request to the plurality of drones, wherein the request indicates that each of the plurality of drones is to return to an emergency landing site to be selected from a set of predetermined emergency landing sites. The emergency landing site for each drone can be based in part on the location of the drone at the time of transmittal of the request.
