“…The ultrasonic frequencies used in these systems are useful for localizing changes, thanks to short wavelength and highly linear structural response. MassHog uses a similar technique, but at near-resonance frequency bands which are more sensitive to added mass [8].…”

“…Structural vibrations are an ideal modality for activity monitoring in the harsh farm environment. They have been used in many settings to provide occupant activity and health monitoring [5,6,8,11,13,20,21]. In the farm environment, this approach has shown sensitivity to pig activities and robustness against the present hazards [2,5].…”

“…MassHog uses the principle of induced vibrations, with near-resonance frequency bands instead of ultrasonic frequencies. These frequencies have been used for occupant detection in past work [8] and enable better sensitivity to mass changes through mode shape and frequency response analysis [3].…”

In the swine livestock industry, weight tracking is commonly used to track health and growth of pigs. This is especially crucial during the farrowing period, where mother sows and their newborn piglets are housed together to facilitate nursing. Existing weight measurement methods, however, either provide only sporadic snapshots or have scalability and reliability issues in the harsh environment of industrial farms. This paper presents MassHog, a multi-layered system for ubiquitous weight measurement in harsh environments, such as pig pens, using structural vibrations. MassHog combines an existing sensor concept with actuated vibrations to weigh both piglets and adult hogs together. We evaluate the components of this system through testing deployments, including at real-world operating pig farms. Preliminary results show less than 2 kg mean absolute error for adult hogs.

A Survey on Seismic Sensor based Target Detection, Localization, Identification, and Activity Recognition

Current sensor technologies facilitate device-free and non-invasive monitoring of target activities and infrastructures to ensure a safe and inhabitable environment. Device-free techniques for sensing the surrounding environment are an emerging area of research where a target does not need to carry or attach any device to provide information about its motion or the surrounding environment. Consequently, there has been an increasing interest in device-free sensing. Seismic sensors are extremely effective tools for gathering target motion information. In this paper, we provide a comprehensive overview of the seismic sensor-based device-free sensing process and highlight the key techniques within the research field. We classify the existing literature into three categories, viz., (i) target detection, (ii) target localization, and (iii) target identification, and activity recognition. The techniques in each category are divided into multiple subcategories in a structured manner to comprehensively discuss the details. We also discuss the challenges associated with contemporary cutting-edge research and suggest potential solutions.
