This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,857.

Summary of the Inventive Concept

The inventive concept expands the core technology of portable markers from ice hockey to various industries, including precision farming, search and rescue, environmental pollution tracking, and disaster response, offering adaptable and versatile solutions for diverse terrain surfaces and use cases.

Background and Problem Solved

The original patent for portable markers in ice hockey had limitations in its design and functionality, restricting its applicability to other surfaces and industries. The new inventive concept addresses this limitation by adapting the core technology to cater to different terrain surfaces, such as soil, water, and rubble, and various use cases, thereby solving the problem of restricted applicability.

Detailed Description of the Inventive Concept

The new inventive concept comprises a portable marker with a stepped peripheral wall, an inner wall defining an inner hollow, and a bottom wall with a friction surface. The marker is designed to be adaptable to various terrain surfaces and use cases, including precision farming, search and rescue, environmental pollution tracking, and disaster response. The marker can receive different tools or sensors, such as farming tools, sensors for detecting pollutants, or visibility aids for low-light conditions, to enable customized functionality. The stepped peripheral wall and friction surface ensure stability and grip on diverse surfaces, while the inner hollow allows for the integration of various components.

Novelty and Inventive Step

The new claims introduce novel applications and use cases for the portable marker technology, which were not anticipated by the original patent. The inventive step lies in the adaptation of the core technology to cater to diverse terrain surfaces and industries, thereby expanding its applicability and versatility.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include variations in the marker's shape, size, and material to suit specific industries or use cases. For instance, a smaller, lighter marker could be designed for search and rescue operations, while a larger, heavier marker could be used for precision farming. The integration of different sensors or tools could also enable customized functionality for various applications.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in various industries, including precision farming, search and rescue, environmental pollution tracking, and disaster response. The adaptable and versatile design of the portable marker enables it to cater to diverse terrain surfaces and use cases, making it an attractive solution for industries seeking customized and effective solutions.
