Laser Level Signal Pairing via Rotation Speed Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In worksites with multiple laser levels, there is a challenge in ensuring that the laser light detector analyzes signals only from the intended laser level, preventing miscommunication and incorrect processing of laser signals from other levels.
Innovation Solution
The solution involves pairing rotary laser levels and detectors by managing their communications through adjusting the laser's rotation speed and emitting patterns, where the detector processes only laser beams received within an expected portion of the panel and analyzes intensity and rotation characteristics to confirm the laser's origin.

1Productivity
If multiple laser levels operate simultaneously in a worksite, then productivity increases through parallel operations, but signal interference and miscommunication between laser levels and detectors increase
Solution Approach 1:
The patent segments the communication spectrum by assigning different rotation speeds to different laser levels. Each laser level operates on a unique rotation speed (e.g., first laser level at speed V1, second laser level at speed V2), creating distinct communication channels. The detector identifies and processes signals based on their specific rotation speeds, allowing multiple laser levels to operate simultaneously without interference.
Solution Approach 2:
The patent changes the rotational speed parameter of the laser beams to encode identification information. By varying the rotation speed parameter (angular velocity ω), each laser level creates a unique signal characteristic. The detector measures the rotation speed of received laser signals and uses this parameter to identify the source laser level, enabling reliable communication in multi-laser environments.
2Reliability
If the detector processes all received laser signals, then no signal is lost, but processing time and computational load increase
Solution Approach 1:
The patent performs preliminary filtering of laser signals based on their rotation speeds. Before full processing, the detector first identifies the rotation speed of each received signal and compares it against the expected rotation speed of the paired laser level. Signals with matching rotation speeds proceed to full processing, while non-matching signals are quickly discarded. This preliminary speed-based filtering reduces processing time while ensuring no valid signals are lost.

AI summary
A laser level assembly is provided. Various methods of managing communications between laser levels and detectors are provided. In one or more methods, upon receiving a selection of a communication channel the laser level emits a laser with certain characteristics, such as by adjusting the rotation speed, rotational direction, and/or emitting the laser in a repeating on/off pattern.
