The plurality of control parameters includes a power-mode control parameter and a location-determination control parameter. The processing circuitry configures a power-mode of the device based on the power-mode control parameter, and determines a location characteristic of the device based on the received location-related data and the location-determination control parameter.

Methods and devices useful in performing precise indoor localization and tracking are provided. By way of example, a method includes locating and tracking, via a first wireless electronic device, a plurality of other wireless electronic devices within an indoor environment. Location ambiguity mitigation is performed using characteristics of signals received by a reference node used to generate a radio frequency map of electronic devices.

A method for determining the geographical position of at least one equipment unit using a device constrained to move with the equipment unit, the method including a first step of determination by the device, when the latter is fixed and has not been subjected to any movement for a first particular time, of network data including the identifiers of beacons of communication networks situated in the environment of the device and the Received Signal Strength Indication of the signals sent by each beacon, a second step of said device sending the network data to a data processing unit via a communication network if the communication network is available, the determination step and the sending step being repeated after each movement of the device to a new position.

A vehicle, a vehicle parking assist system, and a parking method, is provided. A powertrain and a steering system may be operated to guide the vehicle into a parking location to complete a drive cycle based on a default tire radius, a tire angular velocity acquired during a drive cycle in response to a steering angle of the steering system exceeding a threshold value, and wheel and GPS vehicle speeds for the drive cycle.

Methods and arrangements for tracking within a parking facility. A module of a mobile device is used to communicate, to a parking server which stores global data relative to parking places in a parking facility, the presence of a vehicle in the parking facility. There is received, via the module, an indication from the parking server of one or more occupied and/or unoccupied parking places in the parking facility. The module is used to detect a parking event of the vehicle relative to one of the one or more occupied and/or unoccupied parking places, and to report the parking event to the parking server. Other variants and embodiments are broadly contemplated herein.
