Locating Objects Inside a Medium Using Code-Modulated Signals

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention relates to a method and device for determining the position of objects by employing materials with unique linear or nonlinear properties placed within a medium possessing different properties. Signals, either code-modulated or unmodulated, are sent and altered by the object, allowing for precise determination of its position in one, two, or three dimensions after removing signal noise.

Use CasesContent extracted from patent full text and abstract with AI.

• Tracking the position of medical instruments or implants inside the human body
• Locating items within industrial equipment for maintenance or safety purposes
• Monitoring the position of robots, drones, or autonomous vehicles in manufacturing processes
• Inventory tracking in warehouses by embedding tags within objects
• Non-invasive location tracking of objects inside opaque or layered materials

BenefitsContent extracted from patent full text and abstract with AI.

• Enables precise multi-dimensional positioning of objects, even in complex or enclosed environments
• Reduces signal noise to improve accuracy in position detection
• Adaptable to a wide range of materials and mediums due to compatibility with both linear and nonlinear material properties
• Supports real-time applications for dynamic monitoring and tracking
• Non-invasive, does not require direct visual contact with the object

Patent Abstract

Method for determining the position of objects, in which objects with at least one linear and/or nonlinear material and/or structural property are introduced into a medium with linear and/or nonlinear properties, wherein the nonlinear material and/or structural properties of the medium do not coincide with the nonlinear material and/or structural properties of the object, and- either a code-modulated signal is transmitted from a component to the object with at least one linear and/or nonlinear material and/or structural property and the signal is converted by the object into another code-modulated signal and transmitted from the object to at least one component,- or a non-code-modulated signal is transmitted from at least one component to the object with at least one nonlinear material and/or structural property and the signal is converted by the object into a code-modulated signal and transmitted from the object to at least one component, wherein the at least one component is arranged outside the medium, and from the code-modulated signals arriving at the at least one component the proportion of noise of the signal is removed and with the signal or signals thus corrected the position of the object in one-, two or three-dimensional direction is determined with a resolution of
