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 20240036200 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 variation in time of the signal. Each binary digit is defined based on whether the signal is above or below a threshold at a specific time instance. The method then compares the received bitstream to a set of stored reference bitstreams, where each reference bitstream represents a distance to the target. The distance to the target is determined by selecting a reference bitstream from the set based on the comparison.

  • The method determines the distance to a target using a time-varying signal and binary digit representation.
  • The binary digits in the bitstream are defined based on the signal's position relative to a threshold.
  • The method compares the received bitstream to a set of stored reference bitstreams representing different distances.
  • The distance to the target is determined by selecting a reference bitstream that matches the received bitstream.

Potential applications of this technology:

  • Distance measurement in various fields such as robotics, autonomous vehicles, and industrial automation.
  • Object detection and tracking systems.
  • Augmented reality and virtual reality applications.
  • Proximity sensors for safety systems.

Problems solved by this technology:

  • Accurate and real-time distance measurement without the need for complex equipment.
  • Reliable detection and tracking of objects.
  • Improved safety in automated systems by providing accurate proximity information.

Benefits of this technology:

  • Cost-effective solution compared to traditional distance measurement methods.
  • High accuracy and precision in determining the distance to a target.
  • Real-time measurements enable quick decision-making in various applications.
  • Versatile and adaptable to different environments and target types.


Original Abstract Submitted

a method for determining a distance to a target comprises: receiving a bitstream of binary digits corresponding to a variation in time of 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 of binary digits to a set of stored reference bitstreams of binary digits, wherein each reference bitstream represents a distance to the target, and determining the distance to the target based on selection of a reference bitstream in the set of stored reference bitstreams based on said comparing.
