Lassen Peak Unveils Terahertz Handheld Scanner for Weapon Detection

In a groundbreaking achievement for public safety technology, Lassen Peak, Inc. has announced the granting of two essential US patents for its innovative handheld scanner, AirFrisk™. This scanner is specifically designed to detect concealed weapons efficiently and non-invasively. After years of rigorous development, the company is now well-positioned to revolutionize security protocols, particularly for law enforcement agencies.

Patenting Milestones

The patents, numbered 12,332,342 and 12,405,367, signify a comprehensive protection of Lassen Peak's intellectual property. The first patent covers the physical apparatus, which includes the handheld scanner and its proprietary radar architecture, while the second focuses on the application methods for detecting concealed weapons from a safe distance. This dual-patent approach not only secures the hardware but also the underlying technology, enabling a robust foundation for commercialization.

Technology Overview

The AirFrisk scanner operates in the 304-311 GHz range, which falls within the submillimeter wave spectrum. This frequency range allows the device to differentiate concealed weapons from everyday items like phones or wallets, thanks to its advanced resolution capabilities. Lassen Peak received authorization in early 2023 from the FCC for testing within a range of 280 to 320 GHz, facilitating further development and deployment in real-world scenarios.

What sets the AirFrisk scanner apart from traditional, fixed-location detection systems is its mobility. Unlike stationary units that require electrical infrastructure, the AirFrisk can be easily transported and used in diverse environments, functioning similarly to personal equipment like body cameras or stun guns. This versatility enhances its practicality for police and security personnel.

Innovative Engineering

At the core of this handheld device lies a custom Radar System on Chip (RSOC), incorporating a phased array with 24 receivers and 8 transmitters on a single chip. This innovation permits programming for various transmitter-receiver combinations, resulting in a significant improvement in signal-to-noise ratio and operational efficiency.

Hatch Graham, co-founder and CEO of Lassen Peak, emphasized the critical importance of obtaining both types of patents: “Securing both device and method patents required a stringent, multi-year strategy, but it is essential for our mission. This multi-patent framework offers a commercial protective barrier that benefits both our investors and the law enforcement agencies that will rely on this technology.”

Furthermore, Dr. Ehsan Afshari, co-founder and Chief Scientist, highlighted the technological breakthroughs required to achieve submillimeter wave imaging in a battery-operated handheld device. He stated, “Our radar system operating above 300 GHz on a single chip necessitated advancements in antenna design, AI, semiconductor technology, and signal processing.” This architecture not only identifies concealed weapons but does so safely and efficiently, consuming a fraction of the power used by conventional mobile devices.

Commitment to Civil Rights

Beyond the technological innovations, Lassen Peak is determined to navigate the complex interface of public safety and civil liberties. To this end, they have welcomed Scott Greenwood, a nationally recognized constitutional rights attorney, to their board. Greenwood’s extensive experience with the ACLU positions him to ensure that the AirFrisk scanner is employed within strict constitutional boundaries, reducing liability risks for law enforcement and protecting the public's rights.

The Vision for the Future

Lassen Peak is based in the Seattle area and combines a unique mix of experts in fields such as ultra-fast wireless communication, imaging radar, AI, and public safety practices. Their mission is to integrate advanced technologies with an urgent need for transformative public safety solutions. As they move forward, Lassen Peak aims to provide law enforcement and community protections that minimize the potential for conflict while ensuring safety against hidden dangers.

In conclusion, the establishment of these patents marks a significant milestone for Lassen Peak and the broader field of public safety technology. The AirFrisk handheld scanner is set to alter the landscape of weapon detection and enhance safety for communities nationwide.
