Solution Overview
Problem
Existing methods for determining the velocity of an inertial frame are plagued by paradoxes related to relativity and require complex systems like GPS or gyroscopes, which are not suitable for continuous variation in velocity measurements.
Innovation Solution
A velocity-measuring device that emits a light beam from a substrate, reflects it off mirrors, and calculates velocity based on the time interval, using a method that reintroduces the concept of universal simultaneity and energy-time theory, allowing for orthogonal measurements without GPS or gyroscopes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS or gyroscope systems are used to determine velocity, then measurement capability is provided, but device complexity and cost increase
Solution Approach 1:
The patent replaces complex mechanical navigation systems (GPS receivers, gyroscopes, accelerometers) with an optical measurement system. A light source emits photons that reflect off mirrors mounted on the vehicle, and the round-trip time of flight is measured to calculate velocity. This substitutes mechanical/electronic navigation equipment with a simpler optical timing system that directly measures velocity without requiring complex sensor fusion algorithms.
Solution Approach 2:
The invention extracts the velocity measurement function from complex integrated navigation systems. By using only a light source, timer, and mirrors, it isolates the core velocity measurement capability from the surrounding complexity of GPS receivers, satellite communication systems, and multi-sensor integration required by conventional approaches.
2Reliability
If conventional velocity measurement systems are used, then velocity can be determined, but the systems cannot handle continuous velocity variation effectively
Solution Approach 1:
The patent enables continuous velocity measurement by repeatedly emitting light pulses and measuring round-trip times at continuous intervals. The system continuously tracks velocity changes by maintaining an ongoing measurement cycle, allowing it to adapt to continuously varying velocity conditions without requiring system reconfiguration or recalibration.
3Device complexity
If light beam round-trip time measurement is used, then velocity can be calculated without GPS, but measurement precision requires accurate timing
Solution Approach 1:
The patent replaces mechanical distance measurement methods with optical time-of-flight measurement. By using the known speed of light and measuring the round-trip time of light pulses, the system calculates distance and velocity with high precision through timing measurements rather than mechanical sensing, achieving accurate velocity measurement with a simpler system architecture.

Implementation Method 1
triggering at a first instant in time the emission of a light beam from a site on a substrate... A mirror is disposed on the substrate at one end of the substrate. The emitted light beam traverses a path towards the mirror, detecting a second instant in time at which the emitted light beam returns to the site after being reflected from the mirror

AI summary
Disclosed herein is a velocity measuring device to be used in a moving frame to determine the velocity of the moving frame. At least one beam of light is emitted from a site in the moving frame and travels to a mirror disposed in the moving frame and back to the site at which the emission occurred, after which the beam is detected by a light beam detector. By measuring the round trip time of the light beam from emission to detection, a factor gamma can be determined from which the velocity of the moving frame can be computed.
