Abstract: A device for checking the consistency of a positioning includes: a transmitter, a receiver, a time measuring unit, a distance determining module and a check module. The transmitter emits at least one signal, and the receiver receives at least four response signals from at least four different response elements. A response element receives the at least one signal and, upon receipt, emits a response signal. The time measuring unit determines, for each response signal, a total delay time from a transmission time of the signal and a reception time of the respective signal. The distance determination module determines a distance to the respective response element based on each total delay time, and the check module performs a consistency check of a determination of a position based on distances to the different response elements. With the device, erroneous distance values may be detected in ground-based positioning systems.

Abstract: Systems and methods are disclosed for receiving, from a client device, a first input that provides a current address associated with a user; receiving, from the client device, a second user input that identifies a target location; and searching a real-estate database to identify a real-estate property associated with the current address. The systems and methods further provide for estimating equity associated with the real-estate property, updating parameters of a loan model based on the target location and the estimated equity, and providing an output of the model for presentation to the user based on the updated parameters.

Abstract: A system for calibrating a transmitting unit includes an arrangement of at least four transmitting units. A first transmitting unit has stored position data with respect to a setpoint position of the first transmitting unit. The first transmitting unit is designed to emit a first transmission signal to each of the three remaining transmitting units, each of which is designed to receive the first transmission signal and, thereafter, to return a first response signal to the first transmitting unit. The first transmitting unit is designed to determine its relative position data with respect to the three remaining transmitting units on the basis of the first response signals returned and to detect a deviation between the stored position data and the relative position data determined and to carry out a calibration of a transmission parameter of the first transmitting unit on the basis of the detected deviation.

A first transmitting unit is designed to emit a first transmission signal to each of the three remaining units, each of which is designed to receive the first transmission signal and, thereafter, to return a first response signal to the first unit. The three remaining units each have stored position data relating to desired positions of the arrangement. The first unit is designed to: determine its relative position data relative to the three remaining units based on the returned first response signals, obtain the stored position data relating to the desired positions from the three remaining units, and assign the determined relative position data to the obtained position data relating to a single desired position to determine the position of the first unit within the arrangement based on the assignment.
