“…For this purpose, the system was created around a Programmable System on Chip (PSoC) 5LP [20], which requires a minimum of external circuitry, but for sensors and electrodes, to manage signal acquisition and processing. Moreover, the inherent reconfigurability of this device allows the implementation of different hardware configurations, enabling a number of applications in this and other fields [19,21,22,23]. In this particular case, the instrument simultaneously monitors ECG, oxygen saturation, and user activity, and can communicate through Bluetooth Low-Energy (BLE) to an external mobile device.…”

Wearable monitoring devices are now a usual commodity in the market, especially for the monitoring of sports and physical activity. However, specialized wearable devices remain an open field for high-risk professionals, such as military personnel, fire and rescue, law enforcement, etc. In this work, a prototype wearable instrument, based on reconfigurable technologies and capable of monitoring electrocardiogram, oxygen saturation, and motion, is presented. This reconfigurable device allows a wide range of applications in conjunction with mobile devices. As a proof-of-concept, the reconfigurable instrument was been integrated into ad hoc glasses, in order to illustrate the non-invasive monitoring of the user. The performance of the presented prototype was validated against a commercial pulse oximeter, while several alternatives for QRS-complex detection were tested. For this type of scenario, clustering-based classification was found to be a very robust option.

“…The use of in-flight reconfigurable devices in avionics is gaining the attention of companies and space agencies. First in-flight reconfiguration was reported by [20] in the context of the FedSat mission [21]. More recently, in the already mentioned Cibola flight experiment, reconfiguration was used for correcting Single Event Upsets (SEU), as well as to adapt the functionality in the FPGA to the requirements of different experiments.…”

This paper describes a reconfigurable architecture for an on-board processor to be used in space exploration critical systems. It relies on, a dynamically reconfigurable multi-accelerator hardware architecture that provides transparent reconfiguration and scalable performance, dependability, and power consumption, at run-time. The architecture is integrated under an RTEMS operating system, which manages reconfiguration and fault mitigation in a fully-compatible way with space requirements. In this work, the proposed processor is used to implement a vision-based navigation system, providing fully autonomous adaptation to different phases of a space mission timeline or events that the spacecraft may encounter during its lifespan. Results show that reconfigurability enables the practical usage of Commercial Off-The-Shelf (COTS) Multiprocessor Systems-on-Chips (MPSoCs) in real scenarios. INDEX TERMS Vision-based navigation, reconfigurable on-board processor, high performance embedded computing, real-time operating systems.

“…The configurability and availability of interconnected logic cells in an FPGA are particularly well suited for computationally and data intensive applications [33], [34]. Since most spacebased hardware systems have limited on-board resources reserved for data processing, FPGA devices provide attractive solutions for low cost, dedicated on-board capability for real-time computations [35]- [38]. With an embedded FPGA device on-board, each of the ACS, RGS, and CDSS subsystem provides significant processing capability that can be utilized to implement various signal analysis algorithms if needed.…”

This paper presents the development of an in situ measurement system known as the Debris Resistive Acoustic Grid Orbital Navy/NASA Sensor (DRAGONS). The DRAGONS system is designed to detect impacts caused by particles ranging from 50 micrometers to 1 mm at both low-earth and geostationary orbits. DRAGONS utilizes a combination of low-cost sensor technologies to facilitate accurate measurements and approximations of the size, velocity, and angle of impacting micrometeoroids and orbital debris (MMOD). Two thin layers of kapton sheets with resistive traces are used to detect the changes in resistance that are directly proportional to the impacting force caused by the fast traveling particles. Four polyvinylidene fluoride-based sensors are positioned in the back of each kapton sheet to measure acoustic strain caused by an impact. The electronic hardware module that controls all operations employs a low-power, modular, and compact design that enables it to be installed as a low-resource load on a host satellite. Laboratory results demonstrate that in addition to having the ability to detect an impact event, the DRAGONS system can determine impact location, speed, and angle of impact with a mean error of 1.4 cm, 0.2 km/s, and 5{\deg}. The DRAGONS system could be deployed as an add-on subsystem of a payload to enable a real-time, in-depth study of the properties of MMOD.Comment: 15 page
