Secure communication for autonomous vehicles can be increased by performing authentication steps before the nodes (e.g., vehicles, roadside equipment (RSE), base stations, etc.) are within communications range. For example, a digital certificate management system for mobile nodes, specifically for moving vehicles, can facilitate ultra fast communications between vehicles and other nodes. In some embodiments, the RSE can propagate vehicle node data (e.g., direction, speed, estimated time of arrival, etc.) to other vehicles and/or other RSEs. Consequently, this propagation of data prior to the communication between nodes can facilitate a for efficient authentication system.

Systems and methods for cell ID disambiguation are described. In one embodiment, a method may be disclosed for constructing a neighbor table, comprising: receiving, at a mobile base station, a physical cell identifier (PCI) of a detected neighbor base station from a user equipment (UE); receiving a global positioning system (GPS) position of the mobile base station; and associating the GPS position of the mobile base station with the PCI of the detected neighbor base station in a neighbor table.

This disclosure relates to, among other things, systems and methods for managing the communication of messages between devices using a service system operating as a trusted intermediary. Information indicative of device location and/or orientation may be communicated to the service system, which may use the information to determine whether a transmitting device is oriented and/or otherwise pointed in the direction of an intended receiving device. The trusted service may enforce policy articulated by the receiving device in connection with the communication of a message from the transmitting device to the intended receiving device.

Many embodiments can include a system. The system can comprise one or more processors; and one or more non-transitory computer readable mediums storing computing instructions. The computing instructions can be configured to run on the one or more processors and cause the one or more processors to perform: receiving, at a first sensor coupled in a fixed position relative to an automated door, a signal from a portable sensor associated with a user; in response to receiving the signal from the portable sensor, facilitating a customized opening actuation of the automated door or a customized closing actuation of the automated door, wherein at least one of the customized opening actuation or the customized closing actuation is customized for the user.

The portable device is provided with a photograph unit to acquire, at a first time interval, images with a super wide angle of which a maximum value reaches all peripheral directions around the portable device; a traveling direction calculation unit to calculate a traveling direction of the portable device at a second time interval; an image segmentation unit to segment, as a traveling direction image, an image of a predetermined range where the traveling direction is positioned at a center thereof, from a latest acquired image every time the traveling direction calculation unit calculates the traveling direction; and a display control unit to display the traveling direction image on a predetermined traveling direction display region of a display of the portable device. The display control unit displays a video image designated by a user on a first display region, which is different from the traveling direction display region.

A method and system for determining a heading of a vehicle. The method may include receiving, from a mobile computing device, a request for determining the heading of the vehicle. The method may also include retrieving, at least in response to the request, sensor data generated by a magnetometer of the mobile computing device within one or more first time slots, and obtaining a classifier trained to determine a predicted heading of the vehicle. The method may further include, for the sensor data of each of the one or more first time slots, obtaining a feature vector by extracting features from the sensor data, and determining, based on the obtained feature vector, a predicted heading by inputting the feature vector into the classifier. The method may also include determining the heading of the vehicle based on the obtained one or more predicted headings.

The relative position of a user equipment (UE) within a vehicle is determined using angular measurements, such as angle of arrival (AOA), and optionally ranging measurements, with respect to a number of wireless transceivers within the vehicle using wideband signals. The relative position of the UE with respect to a personal zone or the steering wheel may be determined based on known positions of the wireless transceivers. If the UE is determined to be within the personal zone, at least one functionality of the UE is restricted to avoid driver distraction and, optionally, the operation autonomous driving of the vehicle adjusted. If the UE is worn on the driver's wrist the relative position of the UE with respect to the steering wheel may be similarly determined and operation of the vehicle modified if the UE is determined to be outside a threshold distance from the steering wheel.

A computer-implemented method for detecting medical emergency events may include, via one or more processors, data sensors, and/or transceivers: (1) obtaining sensor data indicative of kinetic actions of a user; (2) analyzing the sensor data to associate the sensor data with a one or more kinetic actions of the user; (3) comparing the one or more kinetic actions of the user with a model of kinetic actions to determine whether the one or more kinetic actions correspond with the model of kinetic actions, with the model being indicative of a medical emergency event; and (4) upon determining that the one or more kinetic actions correspond with the model, contacting medical emergency responders to request medical emergency services for the user. As such, medical emergency events being experienced by a user can be detected, and medical emergency responders may be quickly contacted to provide essential emergency medical services to the individual.

Systems, methods, and computer-readable media for providing a signaling location beacon are provided. Specifically, a physical location for transferring a delivery from a delivery person to a customer can be determined. Also, a physical beacon associated with the physical location can be identified. Further, an interaction between the physical beacon and the delivery person can be detected. For example, the interaction can occur based on the physical beacon and the delivery person being in physical proximity to each other. As follows, in response to the interaction, transmission of a sensory signal to the delivery person can be facilitated to provide perceivable direction information associated with the physical location to the delivery person.

Users of a proximity-based messaging system may be added to one or more proximity-based messaging groups that include users of user devices within an active area for the proximity-based messaging group and/or users meeting other criteria for being added to the group. Proximity-based messaging groups may be associated with events, such as music festivals, concerts, sporting events, and other gatherings and events. The active area of a proximity-based messaging group may correspond to a location of an event, an area surrounding an event, an area within an event location, and the like.
