BOW AIM SIGNAL CONVERTER
Patent Number: US 11566870 Grant Date: 2023-01-31 Filing Date: 2022-07-19
Overview
Filed on July 19, 2022 and granted on January 31, 2023, this U.S. patent captures a tightly integrated electromechanical and optical solution that brings automated ranging and ballistic compensation directly to traditional bow sights. Inventors based in Amarillo, TX and Niwot, CO developed a system that combines laser rangefinder hardware, embedded processors and a device application with an optical coupling assembly to route LED light into fiber-optic sight pin leads. The result is a compact module that interprets range and sensor data, computes a range-display signal with pin-specific tolerance logic, and drives selected sight pins as visible aiming cues without modifying the sight’s external pins. The specification addresses robust mechanical integration (watertight housing, neoprene LED surround and lead-receiver squeeze assemblies) and optical isolation to prevent cross-talk between channels while placing LEDs directly on a primary PCB for reliable alignment and serviceability.
Key Features
- Embedded device application with a pin-lighting algorithm that maps measured range to calibrated pin ranges and display actions (colors, blinking, intensity).
- Optical coupling assembly (LED surround, lead tunnels, optical line holders) that channels LED output into fiber-optic sight leads and prevents light pollution between pins.
- Integrated sensors (multi-axis gyroscope, pressure/temperature inputs) supporting ballistic adjustments and orientation-aware display.
This patent showcases precise, field-ready integration of optics, electronics and software for competitive and hunting archery. Its approach illustrates broader trends in sensor-driven aiming devices and embedded optical interfaces across sports and defense accessories.
Invention Details
Abstract: A range finder assembly comprising one or more sight pin leads having a light emitting end and a light receiver end, one or more PCBs, a range finder assembly, one or more LEDs, a power supply, a device application and an optical coupling assembly.
