Solution Overview
Problem
Current methods for accessing data encoded in spatial codes, such as QR codes, are cumbersome, requiring users to unlock and manipulate their mobile devices to capture and decode the information, which is inefficient and time-consuming.
Innovation Solution
Implementing a system that uses optical beacons to continuously transmit encoded data as light signals, which can be received by an apparatus with a receiver, allowing for faster access to encoded data without the need to unlock or manipulate the client device, using a receiver diode and LED to capture and decode the light signal, and display the information on a connected device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user uses a mobile device to access data encoded in a spatial code, then the user can obtain the encoded information, but the user must unlock the device, locate and manipulate the camera application, focus and zoom the camera, and capture the picture or video, which is cumbersome and time-consuming
Solution Approach 1:
The patent replaces the mechanical camera capture system with an optical receiver system. Instead of using a camera to capture and process images of spatial codes, the system uses a receiver that passively receives optical signals transmitted by the spatial code carrier. This substitution eliminates the need for manual camera manipulation, focusing, and image processing, significantly reducing the time and effort required to access encoded data.
Solution Approach 2:
The spatial code carrier continuously transmits optical signals that automatically activate the receiver without requiring user intervention. The system performs data transmission and reception autonomously, eliminating the need for users to manually capture, process, and decode spatial codes. The receiver simply needs to be positioned within the field of view of the spatial code carrier to automatically receive and process the transmitted data.
2Productivity
If a user manually captures and decodes spatial codes using a camera application, then the user can access encoded information, but the process requires multiple steps including unlocking the device, locating the camera application, focusing, and capturing
Solution Approach 1:
The patent replaces the complex mechanical camera system with a simplified optical receiver system. The receiver uses optical components to detect and decode transmitted signals directly, eliminating the need for camera capture, image processing, and manual decoding operations. This substitution dramatically simplifies the data access process while improving productivity.
Solution Approach 2:
The spatial code carrier continuously transmits optical signals in advance, so that when the receiver is activated, the data is already being transmitted. This preliminary continuous transmission eliminates the need for the receiver to capture and process spatial codes in real-time, simplifying the reception process and improving data access speed.

Data Source
AI summary
An apparatus to perform fast data access comprises a receiver, a processor, and a memory. The processor receives using the receiver a light signal from a light source. The light signal can be structured to generate a temporal code. The light source is an optical beacon that includes a Light-Emitting Diode (LED). The processor then decodes the light signal to generate a network address, and causes a display of a client device coupled to the apparatus to display information based on the network address. The network address can be a Uniform Resource Locator (URL) address and the information based on the network address includes a webpage associated with the URL. Other embodiments are described herein.
