Solution Overview

Problem

Current methods for acquiring and tracking a target's location in 3D space, such as in a performance area, suffer from inaccuracies due to reliance on IR and wireless signals that are susceptible to interference and calibration issues, especially when operating in large geographic areas, and lack automated light sources that can operate at distances beyond 150 feet with controllable tracking.

Innovation Solution

A system and method that uses adaptive methodologies and technologies to track targets passively or actively, integrating lighting, audio, video, and projection systems, employing geo-fencing, reflective elements, and multi-point calibration to ensure accurate tracking and alignment in 2D and 3D spaces, utilizing cameras, GPS, and wireless signals for precise location acquisition.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If IR and wireless signals are used for target acquisition, then target location can be obtained, but the system is susceptible to signal loss, interference, and temperature fluctuations leading to inaccuracies

Engineering Contradiction:
Improvetarget location accuracyVSAvoidsignal stability
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The patent combines multiple target acquisition technologies (visual recognition, IR, wireless signals, RFID) into a hybrid system that cross-validates data from different sources. This multi-modal approach ensures that when one signal type fails or becomes inaccurate, other sensors can compensate, thereby improving both reliability and measurement precision simultaneously.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system implements continuous feedback loops where target acquisition data is constantly monitored and validated against expected parameters. When signal quality degrades or accuracy drops below thresholds, the system automatically adjusts sensor sensitivity, switches between active and passive modes, or triggers recalibration procedures to maintain reliable and accurate target tracking.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If visual acquisition is used for target tracking, then ease of operation is improved, but mechanical misalignment and non-flat surfaces prevent successful alignment to a single point

Engineering Contradiction:
Improvetarget acquisition simplicityVSAvoidalignment accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The system performs preliminary calibration and alignment procedures before actual target tracking begins. Mechanical fixtures and optical axes are pre-adjusted using reference targets and alignment tools, and software compensation parameters are pre-calculated for known surface irregularities. This preliminary preparation ensures that the simplified visual acquisition process maintains high precision without requiring complex real-time adjustments.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts acquisition parameters such as field of view, focal length, and sensor sensitivity based on detected target characteristics and environmental conditions. When operating on non-flat surfaces or with misaligned fixtures, the system modifies camera angles, adjusts focus distances, and applies geometric correction algorithms to maintain accurate single-point alignment while preserving ease of operation.

Inventive Principle:
Principle #35Parameter changes

3Length of stationary object

If current light sources are used for illumination, then operation is possible up to 150 feet, but automated tracking and controllable alignment beyond this distance cannot be achieved

Engineering Contradiction:
Improveoperational distanceVSAvoidautomated tracking capability
Core Design Contradiction:
Length of stationary objectVSExtent of automation

Solution Approach 1:

The illumination system is divided into multiple distributed light sources positioned at different locations rather than relying on a single powerful source. Each light source is equipped with its own sensor and control unit, enabling independent automated tracking. This segmentation allows the system to cover larger distances and areas while maintaining automated alignment capabilities, as each module operates autonomously within its range.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent replaces manual mechanical alignment systems with automated optical and electronic alignment mechanisms. Sensors detect target position and automatically adjust light source orientation and focus using motorized mounts and software control, eliminating the need for manual mechanical adjustment. This substitution enables automated tracking at extended distances where manual alignment would be impractical or impossible.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Measurement precision

If multiple acquisition technologies are used together, then target location can be obtained, but the complexity of integrating lighting, video, audio, laser, electronic, wireless and mechanical systems prevents reliable target acquisition

Engineering Contradiction:
Improvetarget location accuracyVSAvoidsystem integration complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent employs a universal control architecture and standardized communication protocols that allow different acquisition technologies (visual, IR, wireless, RFID) to interface through common standards. A central control system with unified software manages all sensors and actuators, providing a single point of integration that reduces complexity while maintaining the precision benefits of multi-technology fusion.

Inventive Principle:
Principle #6Universality (Multi-functionality)
