[Object] To provide a navigation system, a client terminal device, a control method, and a storage medium capable of guiding people to a location with a high degree of security on the basis of information about feelings of people associated with the location.

[Solution] The navigation system includes: an acquisition unit that acquires position information indicating a position of a client terminal device and information related to a feeling of a user of the client terminal device; a generation unit that generates a degree of security of the position indicated by the position information on a basis of the position information and the information related to the feeling of the user, to generate a feeling map; an estimation unit that estimates a location with a high degree of security on a basis of the feeling map; a guidance generation unit that generates guidance for guiding the user of the client terminal device to the location with the high degree of security; and a provision unit that provides the guidance to the user of the client terminal device.

Described herein are techniques for receiving an alert associated with an entity and dynamically determining, based on the alert and on substantially real-time attributes for the entity, a geographically dispersed group in which each member of the geographically dispersed group either is a device associated with the entity or shares at least one attribute with the entity. The techniques further include requesting information about the entity from the geographically dispersed group, receiving information from at least a subset of the group, and taking action responsive to the alert based on the received information.

A portable alarm system is disclosed. The portable alarm system includes a portable base station, which has an outer housing that encloses a power supply and a secondary protective housing. The secondary protective housing encloses at least a controller and a cellular modem that are electrically connected to each other. An energy storage device, such as a super capacitor, is configured to maintain a store of energy and is electrically connected to the controller and the cellular modem to provide an alternative power source thereto.

A security and automation system comprising a controller, the controller comprising a device memory, a processor, a display and communication interfaces, a controller application installed in the device memory of the controller and modules in communication with the controller, each of the modules comprising a processing unit, a WLAN chipset, a power unit and peripherals. For discovery and enrollment the modules are configured to operate as access points and, after said enrollment of the modules to the controller, the controller is configured as an access point by instructions processed by the processor of the controller and the modules are configured as stations to form a wireless intranet.

Systems and methods present practical applications to directing emergency alerts from cellular-based message distribution systems to distributed desktop applications via a desktop application gateway. Logic in the desktop applications and their corresponding IP network gateways for the desktop application may direct alerts from the cellular-based system to distributed desktop applications having a connection to the gateway. A distributed application may determine a location of the user and include enhancements to display the alert at a user's computing device. The gateway for the distributed application may store the location information for each logged-in user or registered instance of the user. An interface between the cell broadcast center and the distributed application gateway may allow the gateway to receive the alert, including a region for distributing the alert, from the cell broadcast center, and send the alert to all registered users with a location matching the alert region.

The disclosure is related to adaptive transcoding of video streams from a camera. A camera system includes a camera and a base station connected to each other in a first communication network, which can be a wireless network. When a user requests to view a video from the camera, the base station obtains a video stream from the camera, transcodes the video stream, based on one or more input parameters, to generate a transcoded video stream, and transmits the transcoded video stream to a user device. The base station can transcode the video stream locally, e.g., within the base station, or in a cloud network based on transcoding location factors. Further, the camera system can also determine whether to stream the video to the user directly from the base station or from the cloud network based on streaming location factors.

Systems, devices, and techniques described herein are directed to a tactical wireless base station, and applications thereof. A tactical wireless base station may include a plurality of hardware or software radios configured to facilitate communication over any wireless protocol. The tactical wireless base station may be deployed on an unmanned aerial vehicle (UAV) to search for a wireless signal of a target user equipment (UE) corresponding to a lost hiker, for example, in an area out of range of traditional base stations, and/or to locate the target UE to convey the location to rescuers. In some instances, a tactical wireless base station can be deployed in a handheld device and may coordinate with other tactical wireless base stations in order to triangulate a location of user equipment. Further, the tactical wireless base stations may be deployed during network outages to provide indications of events, such as during emergencies.

A system and a method for receiving local emergency information on a mobile device in a system having a telecommunication network and at least one local communication network having one or more wireless access points. The mobile device receives a general emergency signal over a broadcast channel of the telecommunication network. In response to the general emergency signal, the mobile device connects to one of the wireless access points and transmits a request for transmitting the local emergency information to the mobile device. The mobile device then receives the local emergency information from one of the wireless access points.

The present invention provides the multimodality filtration surveillance comprising of a plurality of filtration stages executed at the backend server to confirm nature of anomaly in an event, the filtration stages comprising: a first filter of a video anomalies detection in the event for a specified time-place value, a second filter of a city soundscape adapted to provide a localized decibel maps of a city, a third filter of a geocoded social network adapted to semantically read and analyze data from one or more social media corresponding to the specified time-place value, and a fourth filter of an event triggered or proactive local participatory surveillance adapted to provide augmented information on the detected anomalies.

A server includes a server communication unit, a server control unit, and a server storage unit, and is connected in a communicable manner to a first vehicle and a second vehicle via the server communication unit. The server control unit transmits an imaging start command to the second vehicle, which runs within a predetermined range from an accident site, in response to the reception of an accident notification associated with positional information on the accident site from the first vehicle, receives an imaged image from the second vehicle, and stores the imaged image into the server storage unit.
