“…While the previous method with survey data was forward approaching (e.g., can ask the survey respondent about their location), this method with video data is backward (or forensic) approaching (e.g., using metadata provided via social media or identifying landmarks within the video itself, without contacting the individual). Video data from household surveillance cameras are increasingly used to check in on children and pets (e.g., Ur et al, 2014;Bernd et al, 2022), provide insurance claim information (e.g., Wong et al, 2009;Ahmad et al, 2019), and protect from theft (e.g., Pandya et al, 2018). As a society, we also are increasingly publicly surveilled waiting at a stoplight by state and local departments of transportation (e.g., Zhang et al, 2022), in a grocery store to better understand retail behavior and prevent theft (e.g., Alikhani and Renzetti, 2022), and even in school classrooms for safety-related and distance learning purposes (e.g., Johnson et al, 2018;King and Bracy, 2019;Fisher et al, 2020).…”

Geocoding is a spatial analysis method that uses address information (e.g., street address, intersection, census tract, zip code, etc.) to determine geographical coordinates (latitude and longitude). In recent decades, geocoding has gone beyond its primary use for census and demographic information to novel applications in disaster risk reduction, even to earthquake early warning. Here I demonstrate the usefulness of geocoding techniques to earthquake early warning systems as applied to case studies that relied on survey response data and crowd-sourced video footage. These datasets were initially collected to understand the efficacy of tests conducted on ShakeAlert®, the earthquake early warning system for the West Coast of the United States, and how people behave during earthquakes, respectively. Geocoding these data can improve our overall technical understanding of the system, demonstrate whether individuals take protective actions such as ‘Drop, Cover, and Hold On’, and spotlight community demographics that the system is reaching or unintentionally missing. The combination of these social science datasets with geocoding information deepens our knowledge of these fundamentally human-centered systems, including how to improve the distribution of alerts for people and individuals with access and functional needs. In the future, this work may help verify U.S. Geological Survey ‘Did You Feel It?’ responses and seismic intensity, especially in regions with sparse seismic networks.

This paper is principally intimate the updated technology of burglar alarm using sensor. Here magnetic field sensing element plays an important role in providing the range of the magnetic field. In recent days robbery in home and department stores are increasing more frequently. Due to this people feel less secure in their life. Burglar alarm is the technology that uses sensors to detect and measure the magnetic field strength. To avoid this type of scenario here comes burglar alarm system. This alarm indicates whether there is any theft in home, bank, office, jewelry shops, grocery stores and in many other places. This updated alarm system includes a sensing element which will detect magnetic field and translate them into commands for the alarm to initiate the move. This paper offers an updated system of burglar alarm using hall sensor. The sensor detects the magnetic field and passes the information about magnetic field strength and the output is displayed in the 16x2 LCD display.

“…Infrared (IR) sensors play a vital role across various fields, serving critical functions in applications such as sensing, night vision capabilities, and environmental monitoring for security, safety, and pollution detection. They are also employed in automotive safety enhancement, medical diagnostics, reliable communication, and remote sensing, among others [1][2][3][4][5][6]. Dual-band IR sensors operate simultaneously in two distinct infrared bands, providing an enhanced perspective of the monitored environment.…”

In this paper, we propose a dual-band and spectrally-selective infrared (IR) absorber based on a hybrid structure comprising a patterned graphene monolayer and cross-shaped gold resonators within a metasurface. Rooted in full-wave numerical simulations, our study shows that the fundamental absorption mode of the gold metasurface hybridizes with the graphene pattern, leading to a second absorptive mode whose properties depend on graphene’s electrical properties and physical geometry. Specifically, the central operation band of the absorber is defined by the gold resonators whereas the relative absorption level and spectral separation between the two modes can be controlled by graphene’s chemical potential and its pattern, respectively. We analyze this platform using coupled-mode theory to understand the coupling mechanism between these modes and to elucidate the emergence and tuning of the dual band response. The proposed dual-band device can operate at different bands across the IR spectrum and may open new possibilities for tailored sensing applications in spectroscopy, thermal imaging, and environmental monitoring.
