Abstract: Technologies for guided navigation include one or more mobile computing devices and one or more location servers. A requestor mobile computing device establishes a secure data connection with a location server and sends a location request to the location server via the secure data connection. The request identifies a target and includes a request for directions. The target may be a geographic location or a target mobile computing device. The location server determines a route from the requestor mobile computing device to the target. If the target is a target mobile computing device, the location server may perform a positioning procedure with the target mobile computing device. The location server sends a response to the requestor mobile computing device that is indicative of the route from the requestor mobile computing device to the target. The response may include an image indicative of the route. Other embodiments are described and claimed.

Abstract: In various implementations, a condition of one or more screens of a device may be determined. A user may select a return application that facilitates capturing image(s) of device screen(s). A user may capture images of a screen of using a camera of the same device or another device. In some implementations, the user may position the device proximate a mirror such that the device can capture an image of one or more screens of the device. The captured image(s) may be processed and/or analyzed to determine if the screen of the device is damaged. In some implementations, notifications based on the condition of the device screen(s) may be transmitted. A price for the device may be determined, in some implementations based on the condition of the screen.

Abstract: In one embodiment, a device in a network maintains a plurality of network paths for a media session. The device identifies a subset of data for the media session as requiring redundancy. The device sends a packet in the identified subset of data for the media session as redundant packets via two or more of the plurality of network paths for the media session. The device sends a particular packet outside of the identified subset of data for the media session non-redundantly via one of the plurality of network paths for the media session.

Abstract: An apparatus for supplying additives into a coker drum includes an inlet for supplying a hydrocarbon feed stream into the coker drum and conduits along the circumference of walls of the coker drum. Each conduit has an injection nozzle to supply additives inside the coker drum. An injection control system controls the operation of the injection nozzles such that 1) one or more of the injection nozzles placed within a first distance above a vapour liquid interphase of the hydrocarbon feed stream are configured to supply the additives; and 2) supply of the additive discontinues from a particular injection nozzle when a distance between the injection nozzle and the vapour liquid interphase is less than or equal to a second distance. The apparatus optionally includes a mechanical drive system moving at least one of the conduits based on the level of the vapour liquid interphase in the coker drum.
