Abstract: Systems and methods of the present disclosure provide techniques to locate target devices. An electronic message is sent to a set of landmark devices, signaling each landmark device to transmit echo-request packets to a target device and to other landmark devices and measure network-communication delays. Indications of the network-communication delays are received from the set landmark devices. A first sequence is formed by sorting the set of landmark devices relative to the network-communication delays between the target device and each landmark device. For each respective landmark device, an additional sequence is formed by sorting other landmark devices relative to the network-communication delays between the respective landmark device and the other landmark devices. A sequence-matching operation is applied to the first sequence and the additional sequences to form a ranking of the set of landmark devices relative to the target device.

Abstract: Systems and methods of the present disclosure provide a way to pinpoint where a target device associated with an IP address is physically located within a geographical region. Network-communication delays between landmark devices and the target device are determined and used to generate sequences capturing relative delay relationships between the landmark devices and the target device. The sequences are used to determine a ranking via a sequence-matching approach. For each pair of landmark devices, a geographical boundary that divides the geographical region into a target partition and a second partition is determined. The target partition includes a first landmark device of the pair and the second partition includes a second landmark device of the pair. The target device is located where the target partitions for the pairs overlap. Network tomography can be applied to increase accuracy.

Abstract: Disclosed embodiments provide techniques for intelligent media sharing with visualized positioning layout in real time. A floor plan is retrieved corresponding to the physical location of a sender electronic device. A zone boundary corresponding to the physical location of the sender electronic device is determined. A list of potential recipient electronic devices within the zone boundary is generated. A floor plan view is rendered on the sender electronic device. A graphical representation of the potential recipient electronic devices on the floor plan view is rendered, overlaid in a semi-transparent manner with a media selection interface on the sender electronic device. A selection is received for one or more media items using the media selection interface. A send request is received for one or more potential recipients, resulting in sending the one or more media items to at least one potential recipient in response to receiving a user interface request action.

Abstract: The disclosure involves wireless electric power sharing between vehicles. A first vehicle sends a charging request, wherein the first vehicle is at least partially powered by a first on-board rechargeable electricity storage. The first vehicle receives a response to the charging request from a second vehicle which is at least partially powered by a second on-board rechargeable electricity storage, and a communication channel is established between the first and second vehicles. The first on-board rechargeable electricity storage is charged using energy stored in the second on-board rechargeable electricity storage and wirelessly transferred from the second vehicle to the first vehicle. The charging is controlled with information exchanged between the first and second vehicles over the communication channel.

Abstract: Systems, methods, and computer-readable media are described for implementing an active-active transaction protocol according to which multiple sites can each provide active services such as executing update transactions that insert, modify, or delete data records. An active-active transaction protocol utilizes affinity records corresponding to both transactions that have been received as well as the data records those transactions are updating to determine which site should handle execution of an incoming update transaction. An affinity record defines a relationship between a data record and a site that determines whether and where a transaction seeking to update that data record will be routed for processing. Conflict handling mechanisms are also provided by the active-active transaction protocol to ensure data consistency between the multiple sites.

Abstract: Automated devices send messages of a first batch sequence individually to a target queue of a receiving node of a cluster of server nodes, the messages having a different sequence number indicative of their relative positions within the batch sequence, and each is associated with a first logic unit of work identifier. In response to determining that a message counter meets a threshold, a force commit packet is generated to include the sequence number of the last batch message sent to the target queue. If the force commit packet sequence number is not the last position number within the batch sequence, a second logic unit of work identifier is associated with a subset sequence of the batch of messages having sequence numbers spanning from the first number to the force commit packet sequence number, and the subset sequence messages are committed to the receiving node target queue.
