Title: Hans Magnus Ewald - Innovator in Mobile Device Positioning

Introduction

Hans Magnus Ewald is an inventor based in Oslo, Norway. He is currently associated with Sonitor Technologies AS, where he focuses on innovations in mobile device positioning technologies. Although he has not yet been granted any patents, his work is significant in the field of wireless communication and location determination.

Latest Patent Applications

Ewald's latest patent applications include two notable innovations. The first application is titled "Determining Locations of Mobile Devices from Wireless Signals." This method involves receiving data that represents distances between pairs of devices in a network. The data is processed to determine coefficients for a system of linear equations, which are then solved to find the coordinates of each mobile device in either two-dimensional or three-dimensional space.

The second application is "Positioning Using Cost Terms." In this system, multiple transmitter units send locating signals to a mobile receiver unit. A processing system identifies the transmitter unit for each signal and determines range data that represents the distance between the transmitter and the receiver. The position estimate for the mobile receiver is calculated by solving an optimization problem that incorporates range data, transmitter positions, and surface data in the environment.

Conclusion

Hans Magnus Ewald is making strides in the field of mobile device positioning through his innovative patent applications. His contributions to wireless signal processing and location determination are paving the way for advancements in this technology.
