Company patents

Sonitor Technologies AS

Sonitor Technologies AS's patent strategy is heavily concentrated in Radar / Sonar / Lidar, accounting for 90.2% of its portfolio, which saw a significant 53.3% YoY growth in 2024 before a sharp 65.2% decline in 2025. Despite this focus, the company also showed an emerging interest in Wireless Networks, with a 30.0% YoY growth in 2024, indicating a potential broadening of its core communication technologies, though this also saw a substantial decline in 2025.

Step-based positioning

Filed:2022-01-20Pub:2025-11-18
Applicant:Sonitor Technologies AS

In a positioning system ( 100 ) for estimating the position of a mobile device ( 7 ), a processing system ( 9 ) receives external-range data, representative of a range between the mobile device and an external unit ( 2, 3, 4, 5 ), and acceleration data representative of acceleration of the mobile device due to its movement as it is carried by a person ( 6 ). The acceleration data is processed in a step-detection algorithm to determine step-distance data representative of a time series of step-data-based distances travelled by the mobile device, and step-distance data is processed to determine a step-data-based position estimate for the mobile device. A position estimate for the mobile device is determined by solving an optimisation problem comprising a first cost term based on distance to positions located at said range from the external unit, and a second cost term based on distance to the step-data-based position estimate or to positions located at a step-data-based distance from said step-data-based position estimate.

Likelihood-based acoustic positioning

Filed:2021-01-20Pub:2025-01-14
Applicant:Sonitor Technologies AS

A positioning system comprising a processing system ( 7; 9 ) configured to receive a first position estimate for a mobile device ( 7 ), and to receive data representative of an acoustic signal received by the mobile device ( 7 ) from one of a plurality of acoustic transmitter units ( 2, 3, 4, 5 ). For each of the acoustic transmitter units ( 2, 3, 4, 5 ), the processing system ( 7; 9 ) determines spatial likelihood data representative of a likelihood of the received acoustic signal having been transmitted by the respective acoustic transmitter unit by comparing a time-of-flight range value with a geometric distance value, representative of a distance between the acoustic transmitter unit and the first position estimate. The processing system ( 7; 9 ) processes the spatial likelihood data to identify a subset of the acoustic transmitter units, and processes information relating to the positions of the acoustic transmitter units in the identified subset and/or relating to the acoustic signals transmitted by the acoustic transmitter units in the identified subset, to determine a second position estimate for the mobile device ( 7 ).
