METHOD AND A DEVICE FOR DETERMINING A DISTANCE TO A TARGET - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240036199 titled 'METHOD AND A DEVICE FOR DETERMINING A DISTANCE TO A TARGET
Simplified Explanation
The abstract describes a method for determining the distance to a target using a time-varying signal based on light transmitted by a light source and reflected by the target. The method involves receiving a bitstream of binary digits that represent the time-varying signal. Each binary digit in the bitstream is determined based on whether the signal is above or below a threshold at a specific time instance.
The method further includes comparing the bitstream to a set of stored reference bitstreams. This set consists of pairs of reference bitstreams that represent a common distance to the target. The first reference bitstream is phase-shifted in relation to the second reference bitstream. By comparing the bitstream to the reference bitstreams, the method determines the distance to the target by selecting a pair of reference bitstreams that closely match the received bitstream.
- The method determines the distance to a target by analyzing a time-varying signal based on light reflection.
- It uses a bitstream of binary digits to represent the signal, with each digit determined by the signal's position relative to a threshold.
- The method compares the received bitstream to a set of stored reference bitstreams.
- The reference bitstreams represent a common distance to the target and are phase-shifted in relation to each other.
- By selecting a pair of reference bitstreams that closely match the received bitstream, the method determines the distance to the target.
Potential applications of this technology:
- Distance measurement in various fields such as robotics, autonomous vehicles, and industrial automation.
- Object detection and tracking systems.
- Proximity sensors for safety applications.
- Augmented reality and virtual reality systems for accurate depth perception.
Problems solved by this technology:
- Accurate and reliable distance measurement without the need for complex equipment or sensors.
- Overcoming limitations of traditional distance measurement methods that may be affected by environmental factors or require direct contact with the target.
- Providing a cost-effective solution for distance measurement in various applications.
Benefits of this technology:
- Improved accuracy and precision in distance measurement.
- Non-contact measurement, eliminating the need for physical contact with the target.
- Real-time distance measurement capability.
- Cost-effective implementation using simple binary digit analysis and comparison techniques.
Original Abstract Submitted
a method for determining a distance to a target comprises: receiving a bitstream of binary digits corresponding to a time-varying signal based on light transmitted by a light source being reflected by the target, wherein each binary digit in the bitstream is defined based on the time-varying signal at a time instance represented by the binary digit being above or below a threshold; comparing the bitstream to a set of stored reference bitstreams, wherein the set comprises pairs comprising a first reference bitstream and a second reference bitstream representing a common distance to the target, wherein the first reference bitstream is phase-shifted in relation to the second reference bitstream; and determining the distance to the target based on selection of a pair of reference bitstreams based on said comparing.
