Custom Aluminum Extrusion Profile Custom Aluminum Extrusion profile is a process of shaping aluminum profiles by forcing it through a die of the desired cross-section. This process involves heating the aluminum billet to a specific temperature and then extruding it through a die using a hydraulic press. The extruded Aluminum Profile can be cut to the desired length and then further processed to meet specific requirements such as drilling, punching, bending, and welding.Custom aluminum extrusion profiles are widely used in various industries such as construction, automotive, aerospace, and electronics. It is a cost-effective way to produce complex shapes and designs with high precision and accuracy. The extrusion process allows for the creation of profiles with different cross-sectional shapes, including round, square, rectangular, and hexagonal.Custom aluminum extrusion profiles offer several benefits, including high strength-to-weight ratio, corrosion resistance, and excellent thermal conductivity. The profiles can also be anodized or painted to provide additional protection against corrosion and to enhance their appearance.Custom aluminum extrusion profiles are highly customizable, and they can be tailored to meet specific design requirements. The profiles can be made in different sizes, lengths, and finishes to suit various applications. They can also be machined or fabricated to create more complex shapes and structures.

Underground drones for emergency response: investigating a sinkhole
# Emergency Response with Underground Drones: Investigating a Sinkhole in Lyon
## Introduction
The Elios 3 made headlines recently during an emergency in Lyon, where an underground drone was the only viable solution to investigate a mysterious sinkhole. This situation underscored the growing importance of advanced technology in managing urban emergencies.
## Benefits at a Glance
| **Access** | Without the Elios 3, it would have been impossible to visualize the extent of the underground space accurately. |
|------------|-------------------------------------------------------------------------------------------------------|
| **Speed** | A flight with the Elios 3 was completed in mere minutes, delivering critical data swiftly. |
| **Safety** | The sinkhole posed significant risks to emergency responders and local residents. The Elios 3 safely entered the area. |
| **Data Quality** | The Elios 3’s LiDAR scan helped determine if neighboring building foundations were threatened by the cavern. |
## Historical Context
Lyon, once known as Lugdunum, has a rich Roman history dating back to 43 BC. Today, modern Lyon continues to interact with its ancient past through attractions like the Roman theaters, archaeological gardens, and aqueducts. However, this connection to antiquity occasionally presents challenges, as the earth can unexpectedly open up, revealing hidden Roman structures beneath the surface. These events necessitate careful monitoring by local authorities to ensure public safety.
## Local Authorities Deploy Cutting-Edge Technology: Drone Emergency Response
In a residential neighborhood of Lyon, a sizable hole emerged adjacent to an apartment building. The Lyon Metropole immediately recognized the potential danger—Roman ruins might lie beneath the city, and the cavity could expand, threatening the building above. Such a collapse would endanger not only the current residents but also those in the surrounding area.
Xenodrone, a specialized inspection firm, was brought in by a contractor for the Lyon Metropole to conduct an urgent assessment. Julien Gay, Xenodrone’s leader and a former firefighter, understands the urgency of such situations and the need for adaptability. He believed the Elios 3, capable of operating as an underground drone, was the perfect tool to collect the crucial data the authorities required.
## Responding to Land Subsidence with an Underground Drone
Upon arriving at the site, Julien discovered a hole positioned just 2.5 meters from the building's wall. He recalled a similar incident a few kilometers away where Roman galleries were uncovered, suggesting the possibility of the same under this location.
Without a drone, obtaining information about a subsidence event safely is challenging. The cavity was pitch-black, its depth uncertain, and whether it was still active unclear. Sending the Elios 3 into the sinkhole was the sole method to acquire clear data in a secure manner. Although the site was unstable, the risks to the drone were far lower than the potential hazards to people in the building and nearby areas.
Julien was tasked with determining if there was an imminent risk of further land subsidence and whether the cavern extended toward the building. This meant he needed to capture LiDAR data within the space to construct a detailed 3D model for analysis. Thanks to the Elios 3’s rapid flight capabilities and the density of points its LiDAR scanner generates, the inspection flight was accomplished in just four minutes.
## Using an Underground Drone to Analyze Subsidence
Julien gathered the LiDAR scan as swiftly as possible. He piloted the drone vertically into the cavity and performed a 360-degree turn inside the void. Once the FlyAware point cloud displayed a full model, he guided the drone out of the space.
The initial findings revealed the cavity was extensive, descending six meters deep. The Elios 3’s precision allowed Julien to provide precise details about the cavern’s dimensions and layout.
Back at his office, Julien promptly prepared a report using Inspector 5 to deliver clear outcomes to the local authorities. The LiDAR scan could assess the risk to the building near the hole, while the visual data provided surveyors insights into the contents of the cavern—was it a geological feature or remnants of Roman architecture?
## The Flexibility of the Elios 3 Enhances Emergency Response
In missions like this, where circumstances can evolve rapidly, the Elios 3 is the ideal instrument for swift data acquisition. A four-minute flight was all it took to gather data unattainable by any other means. Moreover, the data was collected safely without anyone needing to approach or enter the hole. The guaranteed safety of the operator was a significant relief to the local emergency response team and minimized inspection-related risks.
Julien emphasized how this mission bolstered confidence in using drones among stakeholders. "We take pride in our quick response times, and during my firefighting days, I witnessed situations where speed was crucial. Now, with the Elios 3, we can handle routine building inspections efficiently. Clearly, our services are equally valuable in emergency responses to gather vital data for decision-making." Since this operation, Julien’s report helped response teams locate a spring beneath the hole, which was stabilized with 63 cubic meters of fill material.
Today, local authorities can strategize addressing the subsidence confidently, knowing the exact conditions they face. It will also be straightforward for Julien to revisit the site with the Elios 3 to gather additional data if the terrain shifts, allowing for overlays with existing data to monitor changes and predict future movements. The Elios 3 enabled Julien to distinguish himself among competitors and execute a mission where safety and speed were paramount.
