Title: Innovations by Johan Fredrik Näs

Introduction

Johan Fredrik Näs is a notable inventor based in Trondheim, Norway. He has made significant contributions to the field of seismic sensor technology, holding 2 patents that showcase his innovative approach to geological surveys.

Latest Patents

One of his latest patents is focused on the deployment of seismic sensors. This invention involves an arrangement for deploying seismic sensor units on the seabed, utilizing a frame structure designed to carry a container for data registration units and auxiliary equipment. The arrangement includes supports that rest against the seabed and an attachment means for a lifting hook, allowing for efficient raising and lowering by a crane. Additionally, there is a holder for the sensor node that can be positioned on the seabed, connected to the container through a signal cable. A releasable attachment means secures the sensor node in a downwardly extending position, with a latch mechanism designed to release it when necessary.

Another significant patent by Näs pertains to a sensor arrangement and method for the installation and movement of seismic sensors. This invention is intended for seismic surveys of geological formations on the seabed. It involves multiple arrangements equipped with sensor units that collect pressure and shear waves reflected from geological formations. Each sensor unit is held by a carrier connected to a skirt-shaped structure that penetrates the seabed. The carrier can be moved between positions to facilitate mechanical release from the skirt-shaped structure.
