Drones and the Fourth Amendment: Redefining Expectations of Privacy

Drones have gained notoriety as a weapon against foreign terrorist targets; yet, they have also recently made headlines as an instrument for domestic surveillance. With their sophisticated capabilities and continuously decreasing costs, it is not surprising that drones have attracted numerous consumers—most notably, law enforcement. Courts will likely soon have to decipher the limits on the government’s use of drones under the Fourth Amendment. But it is unclear where, or even whether, drones would fall under the current jurisprudence. Because of their diverse and sophisticated designs and capabilities, drones might be able to maneuver through the Fourth Amendment’s doctrinal loopholes. This Note advocates analyzing drones under an adapted approach to the reasonable-expectation-of-privacy test in Katz v. United States. Courts should focus more on the test’s oft-neglected first prong—whether a person exhibited a subjective expectation of privacy—and analyze what information falls within the scope of that expectation, excluding information knowingly exposed to the plain view of the public. This analysis also considers instances when, although a subjective expectation exists, it may be impossible or implausible to reasonably exhibit that expectation, a dilemma especially relevant to an analysis of drones. Courts that adopt the recommended analysis would have a coherent and comprehensible approach to factually dynamic cases challenging the constitutionality of drone surveillance. Until then, the constitutional uncertainties of these cases will likely linger

Thermal Drone Technology Used to Capture Thermoregulation in Wild Sumatran Elephants

Drone technology plays a critical role in supporting conservation efforts for endangered species, not only in terms of species monitoring within various landscapes, but also potentially when applied to behavioral studies to investigate interaction patterns and response to environmental change. We tested a thermal drone to investigate thermoregulation and surface temperature of wild Sumatran elephants in the lowland tropical forest of Jambi, Indonesia. Thermoregulation data was obtained using RGB images and videos, while temperature values were measured from thermal images (R-JPEG) extracted into TIFF equipped with pixel temperature. We detected a visual thermoregulation mechanism known as mud bathing. Our study demonstrated that the trunk functions to draw mud and throw it onto the head, back, and stomach, the tail functions to distribute the mud to all parts of the back of the body, while the ears flapped to keep head temperature cool. Our measurements showed that the surface temperature of Sumatran elephants is between 28.9-30.3°C. The head had a relatively lower temperature than other body parts. This study also revealed that the environmental humidity variable significantly affects the elephant's temperature rise. The use of drone technology for future behavioral studies is recommended as it accurately provides high quality data and can be widely used in any type of terrain

Cities and Drones: What Cities Need to Know about Unmanned Aerial Vehicles (UAVs)

NLC's municipal guide, Cities and Drones, is designed to serve as a primer on drones for local officials, providing insight into the recently released federal rules relating to drone operation, as well as offering suggestions for how local governments can craft their own drone ordinances to encourage innovation while also protecting their cities.Drones have the potential to revolutionize many industries and city services, particularly as their technology advances. There are many applications for drones within the public sector at the local and state level. Drones can be used for law enforcement and firefighting, as rural ambulances, and for inspections, environmental monitoring, and disaster management. Any commercial arena that involves outdoor photography or visual inspection will likely be experimenting with drones in the near future, as will retailers who want to speed up package delivery.However, drones also present challenges. There are some safety issues, for instance, when operators fly their drones over people or near planes. City residents often have privacy concerns when any small device hovering nearby could potentially be taking photos or video. The FAA's final rule on drones left some opportunity for city governments to legislate on this issue. Rather than ban them outright, city officials should consider how this new technology might serve residents or enhance city services

Terrestrial Megafauna Response to Drone Noise Levels in Ex Situ Areas

Drone use has significantly grown in recent years, and there is a knowledge gap on how the noise produced by these systems may affect animals. We investigated how 18 species of megafauna reacted to drone sound pressure levels at different frequencies. The sound pressure level on the low frequency generated by the drone did not change the studied species’ behavior, except for the Asian elephant. All other studied species showed higher noise sensitivity at medium and high frequencies. The Asian elephant was the most sensitive species to drone noise, mainly at low frequencies. Felines supported the highest sound pressure level before showing behavioral reactions. Our results suggest that drone sound pressure levels in different frequencies cause behavioral changes that differ among species, which is relevant to assessing drone disturbances in ex situ environments. The findings presented here can help to reduce drone impact for target species and serve as an experimental study for future drone use guidelines.M.M.P. contract is funded by the European Union “NextGenerationEU” Programa María Zambrano, Ministerio de Universidades, Spain.

The Modern Face of Battle

New technology is entering the battlefield at a rapid pace, changing the way modern battle is conducted. This paper surveys the state of robotic systems, and identifies new technologies of war and the evolving military doctrine of the U.S. military. Our analysis is drawn from historical parallels and current publications. We conclude that the Department of Defense has adopted a high tempo, flexible doctrine that is capable of taking advantage of the evolving mission payloads of unmanned military systems

An embedded multichannel sound acquisition system for drone audition

Microphone array techniques can improve the acoustic sensing performance on drones, compared to the use of a single microphone. However, multichannel sound acquisition systems are not available in current commercial drone platforms. We present an embedded multichannel sound acquisition and recording system with eight microphones mounted on a quadcopter. The system is developed based on Bela, an embedded computing system for audio processing. The system can record the sound from multiple microphones simultaneously; can store the data locally for on-device processing; and can transmit the multichannel audio via wireless communication to a ground terminal for remote processing. We disclose the technical details of the hardware, software design and development of the system. We implement two setups that place the microphone array at different locations on the drone body. We present experimental results obtained by state-of-the-art drone audition algorithms applied to the sound recorded by the embedded system flying with a drone. It is shown that the ego-noise reduction performance achieved by the microphone array varies depending on the array placement and the location of the target sound. This observation provides valuable insights to hardware development for drone audition
