Various embodiments provide systems and method for hybrid monitoring of individuals using both a combination of a user attached monitor device and a user detached monitor device.

A method and apparatus is provided for controlling the operation of an autonomous vehicle. According to one aspect, the autonomous vehicle may track the trajectories of other vehicles on a road. Based on the other vehicle's trajectories, the autonomous vehicle may generate a pool of combined trajectories. Subsequently, the autonomous vehicle may select one of the combined trajectories as a representative trajectory. The representative trajectory may be used to change at least one of the speed or direction of the autonomous vehicle.

An illustrative example embodiment of a location determining device includes a processor that is configured to determine an indicated distance between a first detector and a source based on a signal originating at the source and detected by the detector, determine a second distance between the source and a second detector that does not have a direct signal path to the source based on a signal originating at the source and detected by the second detector, and determine a reliability of the indicated distance for determining the location by determining whether the indicated distance corresponds to a direct signal path between the first detector and the source based on a difference between the indicated distance and the second distance.

An object is to enable a receiving side to estimate a position of a vehicle on a transmission side to be estimated with high accuracy. A vehicle-mounted communication device 1 loaded into a vehicle includes a vehicle-to-vehicle communication unit 15, a position estimation information acquisition unit 14 which periodically acquires a plurality of types of position estimation information, a storage unit 11 which stores the plurality of types of position estimation information with acquisition time information representing an acquisition time at which each of the position estimation information has been acquired associated with the position estimation information, and a control unit 10 which causes the vehicle-to-vehicle communication unit 15 to transmit vehicle information, in which among the transmitted plurality of types of position estimation information, the at least one type of position estimation information is the position estimation information with which the acquisition time information representing the latest acquisition time is associated among the one type of position estimation information, and the other type of position estimation information different from the one type of position estimation information is the position estimation information with which the acquisition time information representing the acquisition time closest to the acquisition time at which the one type of position estimation information has been acquired is associated.

An operation management device including: a setting information acquisition unit configured to acquire selected vehicle information set in a user terminal and indicating a selected vehicle selected from a plurality of vehicles; a vehicle information acquisition unit configured to acquire position information and time information at predetermined time intervals, the position information indicating positions of each of the plurality of vehicles, and the time information indicating time at which the position information is acquired, and a display control unit configured to display, on the user terminal, a map image and a position image that is overlapped on the map image, the position image indicating a plurality of positions indicated by the position information corresponding to the selected vehicle, and the position image being displayed in a mode that is determined based on the time indicated by time information.

A method and system for determining a separation distance between a first object and a second object comprises using a search module associated with a first object comprising a first transponder having a unique address. The method includes using a reply module associated with a second object comprising a second transponder having a different, unique address. The method includes the search module transmitting a search signal on a first frequency, said search signal including the address of the first transponder and the address of the second transponder. The reply module receives the search signal and locally validates the address included in said received search signal for the second transponder, whereby, if the validation is positive; the reply module transmits a reply signal on a second, different frequency.
