A method of assistance in controlling the spread of a contagious disease, using networked devices, is disclosed. The method includes upon receiving data relating to infection by the disease of a first user of a first mobile terminal, obtaining a list including data of successive geographical positions of the first terminal over a predetermined period of time, and estimating a region at risk of infection by the first user, and for a second terminal available to a second user: obtaining a geographical position datum of the second terminal during the period of time, and comparing the geographical position of the second terminal to the region at risk by the datum of the second terminal, in the event of a coincidence between the geographical position of the second terminal and the region at risk, activating a human-machine interface connected to the second terminal to inform the second user of a risk

A method and a device for performing communication by using a virtual subscriber identity module are used to provide a mode in which the device can perform communication without a SIM card. The method includes: receiving, by a first device, a virtual subscriber identity module data package sent by a second device by using a short range communications protocol, where the virtual subscriber identity module data package carries a virtual subscriber identity, and the virtual subscriber identity is used to uniquely identify a user using the first device when the first device performs communication in a network provided by a mobile communications operator; obtaining, by the first device, the virtual subscriber identity by using the virtual subscriber identity module data package; and communicating, by the first device by using the virtual subscriber identity, with another device in the network provided by the mobile communications operator.

An exemplary virtual boundary system determines a refined geolocation of a tracking device based on a positioning signal and a correction signal that are accessed from distinct signal sources. The virtual boundary system compares the refined geolocation of the tracking device and a geographic boundary. Then, based on the comparing of the refined geolocation and the geographic boundary, the virtual boundary system provides an alert indicative of the refined geolocation with respect to the geographic boundary. Corresponding methods and systems are also disclosed.

A system, method and storage medium for providing an emergency vehicle alert includes first device transmitting EV data including a current location of an EV to a management server, management server receiving the EV data from the first device, the management server determining a geofence for the EV at least based on the received EV data and geographical map data near the EV, and management server transmitting the determined geofence to a second device. The first device is associated with the EV, and the second device is associated with the another vehicle.

This document is related to enhanced tracking and reporting. An example method may comprise receiving an electronic signal associated with an officer account. The example method may comprise receiving, by a processor, historical data associated with at least one parolee account that is associated with the officer account. The example method may comprise automatically displaying a second set of user interface elements comprising a plurality of sections. The example method may comprise displaying user check-in data in a first section of the second set of user interface elements. The example method may comprise displaying user location data in a second section of the second set of user interface elements. The example method may comprise displaying user interface elements to approve or deny pending check-ins in a third section of the second set of user interface elements.

Disclosed are systems, methods, and non-transitory media for sensing radio frequency signals. For instance, radio frequency data can be received by an apparatus and from at least one wireless device in an environment. Based on the radio frequency data received from the at least one wireless device, the apparatus can determine sensing coverage of the at least one wireless device. The apparatus can further provide the determined sensing coverage and a position of at least one device to a user device.

A system and method for using super geo-fences to improve efficiency of geo-fences is disclosed. A system determines a geo-fence density based on a number of geo-fences in an area around a client system. In response to determining the geo-fence density is greater than a predetermined density value, the system selects a number of geo-fences that is greater than a fixed number of geo-fences that the client system is capable of handling. The system groups the selected geo-fences into a first and second group of geo-fences and generates a super geo-fence that encompasses the first group. The system transmits the first and second group of geo-fences and the super geo-fence to an application stored at the client device. The application adds geo-fence data corresponding to the second group to the client system in response to detecting the client system crossing a boundary of the super geo-fence.

A first system (11) is configured to transmit an interest message, e.g. to a router (21). The interest message specifies criteria identifying data units from an area of interest, e.g. an intersection, which are to be aggregated and comprises at least one parameter specifying how the data units are requested to be aggregated. A second system (1) is configured to receive the interest message from a sender, e.g. a router (21), determine whether the system will return an aggregation of data units matching the criteria, and return a data message comprising an aggregation of data units matching the criteria to the sender (21) if the processing means have determined that the system will return an aggregation of data units matching the criteria. The data units are aggregated in the data message in dependence on how the data units were requested to be aggregated.

Methods and systems for power tool geofence tracking. One embodiment provides a method for power tool geofence tracking and dashboard display. The method includes determining, using an electronic processor with a transceiver, a location of one or more power tool devices and generating, using the electronic processor, a dashboard to simultaneously display a location-based inventory, indication of number of missing tool, and geofence setup of power tool devices within the inventory. The method also includes displaying, using the electronic processor, the dashboard on an electronic display.

A communication device includes: a display section; an AIS receiving section configured to receive automatic identification system (AIS) information; a list creating section configured to create, based on the AIS information about vessels existing in the vicinity of the communication device, a proximity order list in which pieces of specific information for identifying the vessels are arranged in increasing order of proximity to the communication device; and a display control section configured to, when the submersion of the communication device has been detected, control the display section so that the display section displays the proximity order list and so that any one of the pieces of specific information at the top of the proximity order list is in a selected state.
