Light detection and ranging (LiDAR) systems are enabling new applications in the field of spacecraft navigation, planetary exploration, as well as docking and landing operations. Wide time-of-flight (ToF) range, high speed and spatial resolution, tolerance to background (BG) noise, high dynamic range and radiation hardness represent some of key features to operate in this harsh environment. Among all technologies, direct ToF sensors based on CMOS single-photon avalanche diodes (SPAD) and time-to-digital converter (TDC) pixel arrays have gradually earned their place in 3D imaging due to their performance and system integrability [1]–[4].

Modern big data workflows are characterized by computationally intensive kernels. The simulated results are often combined with knowledge extracted from AI models to ultimately support decision-making. These energy-hungry workflows are increasingly executed in data centers with energy-efficient hardware accelerators since FPGAs are well-suited for this task due to their inherent parallelism. We present the H2020 project EVEREST, which has developed a system development kit (SDK) to simplify the creation of FPGA-accelerated kernels and manage the execution at runtime through a virtualization environment. This paper describes the main components of the EVEREST SDK and the benefits that can be achieved in our use cases.

Smart Structures and Materials 1999 conference

This paper discusses research and development efforts directed at producing a passive, smart bolt for infrastructure applications. The smart bolts are fabricated fi om high-strength TRIP (TRansformation Induced Plasticity) Steels. TRIP steels gradually transform from a non-magnetic, austenitic parent phase to a ferromagnetic, martensitic product phase. The stress-assisted (elastic range) and strain-induced (plastic range) phase transitions that inherently occur in the material provide a magnetic signature by which the damage state of the bolt can be determined. The irreversible nature of the phase transformations means that the bolt can passively retain peak strain (i.e., peak damage information) for later interrogation. Several different smart bolt design concepts were considered and evaluated. Design modeling and smart bolt optimization were achieved with the aid of a series of Pro/Engineer solid model renderings and a Pro/Mechanica finite element model analysis. The smart bolt was developed for high-tension fastener applications in the USAF C-130 Hercules cargo aircraft. Alloy design efforts, testing, and evaluation data are presented and discussed. Full-scale, smart aircraft bolt manufacturing is discussed and field application scheduling/evaluation plans are outlined. Extension of the smart bolt technology for construction industry applications is discussed.

The International solid-state Circuits conference (ISSCC) is the flagship conference of the IEEE solid-state Circuits Society. This year, the theme for ISSCC 2017 is "Intelligent Chips for a Smart World." Advances in solid-state circuits and systems continue to propel the ongoing fusion between the physical and virtual worlds. With the resulting growth in sensor deployment, data traffic, and data-center workloads, future systems must employ "intelligent" chips at all levels of the system stack to improve the efficiency at which we acquire, network, store, and process information. Modern applications centered around the Internet of Everything (IoE) and real-time data analytics are driving circuit and system designers toward new ways of leveraging the immense device density and processing power of modern technology. ISSCC covers a spectrum of design approaches in various technical areas and advances, broadly categorized as analog systems, analog-to-digital data-conversion systems, communication systems, digital systems, and innovative topics such as micromachines and microelectromechanical systems (MEMS), imagers, sensors, and biomedical devices, as well as forward-looking solutions that may be several years away from becoming commercial. The ten ISSCC technical subcommittees annually update their analyses of industry trends for the benefit of the community at large. This article summarizes some of these views in selected technical areas.

We outline the possible applications of newly developed single photon avalanche detectors (SPAD) operating at low voltage and fabricated in silicon planar technology, reporting on tests done with scintillators. We envisage the integration of large arrays of identical sensors, employing a common read-out mode in order to achieve a high resolution and high sensitivity solid state photomultiplier. The applications of such a device would be many, particularly if we consider that we are also working on the production of micro-optical components, perfectly suited for the lossless coupling of these photosensors to several light sources (lasers, ordinary and scintillating fibres, scintillators, optical devices), by exploiting the promising DLI technology (deep lithography with ions). Crossed time-of-flight and amplitude measurements between SPADs and usual photomultipliers, coupled to scintillators, have allowed to compare their relative performance. Specific issues regarding the SPAD and the scintillating fibre readout are presented, also in view of possible applications in the field of particle/radiation tracking systems.

A new Graphical User Interface (GUI) was developed using Laboratory Virtual Instrumentation Engineering Workbench (LabVIEW) for a high-resolution, high-sensitivity solid state X-ray Image Intensifier (SSXII), which is a new x-ray detector for radiographic and fluoroscopic imaging, consisting of an array of Electron-Multiplying CCDs (EMCCDs) each having a variable on-chip electron-multiplication gain of up to 2000x to reduce the effect of readout noise. To enlarge the field-of-view (FOV), each EMCCD sensor is coupled to an x-ray phosphor through a fiberoptic taper. Two EMCCD camera modules are used in our prototype to form a computer-controlled array;however, larger arrays are under development. The new GUI provides patient registration, EMCCD module control, image acquisition, and patient image review. Images from the array are stitched into a 2kx1k pixel image that can be acquired and saved at a rate of 17 Hz (faster with pixel binning). When reviewing the patient's data, the operator can select images from the patient's directory tree listed by the GUI and cycle through the images using a slider bar. Commonly used camera parameters including exposure time, trigger mode, and individual EMCCD gain can be easily adjusted using the GUI. The GUI is designed to accommodate expansion of the EMCCD array to even larger FOVs with more modules. The high-resolution, high-sensitivity EMCCD modular-array SSXII imager with the new user-friendly GUI should enable angiographers and interventionalists to visualize smaller vessels and endovascular devices, helping them to make more accurate diagnoses and to perform more precise image-guided interventions.

Cell-based assays are powerful tools to characterize cell- or tissue-specific physiological behaviors under external biochemical stimuli. External biochemical stimuli trigger endogenous cellular mechanisms that produce a cascade of physiological changes, resulting in easily measurable signals. Cell-based assays are widely used for large-scale drug screening in the pharmaceutical industry, where in vitro cultured cells are used to characterize the potency and toxicity of thousands of chemicals, leading to new drug development. This is particularly relevant in individualized medicine as patient-derived cells can test personalized drug responses. However, most current cell-based assays are conducted on single-modality sensors (electrical or optical only), which cannot capture the complexity of multi-parameter physiological responses. Sequentially transporting cell samples through different sensor platforms results in low throughput and potential abrogation of cell functions, while parallel monitoring of multiple samples with different modalities is subject to cell-to-cell variation even in a homogeneous cell population.
