Three-wavelength SPAD-based photoplethysmography
2022 17th Conference on Ph.D Research in Microelectronics and Electronics (PRIME), 2022Continuous and real-time monitoring of cardiorespiratory signals by portable and accurate instrumentation is very important for the early diagnosis of cardiovascular diseases. We aim to present a novel photoplethysmography device to assess changes in blood oxygen saturation and beat-bybeat pulse waves of finger blood volumes not affected by possibly ...

On the Information Transfer Rate of SPAD Arrays
2020 IEEE Wireless Communications and Networking Conference (WCNC), 2020In this paper the information transfer rate of a single-photon avalanche diode (SPAD) array is investigated. The SPAD array is modelled as a discrete-time Gaussian channel with signal-dependent mean and variance. The SPAD dead time is a parameter which affects the extent of this signal dependency.

2014 IEEE International Symposium on Circuits and Systems (ISCAS), 2014
We present a low-light vision system platform that enables the testing and implementation of optic flow algorithms and kernel operations for micro-air vehicle navigation and obstacle avoidance capabilities. The system includes a 7×7 array of actively-quenched large-area single photon avalanche diodes, each having a compact 9-bit analog counter, and ...

The number of patients admitted to toxicological units due to acute liver failure (ALF) and acute-on-chronic liver failure (AoChLF) has been increasing in recent years. Various methods of extracorporeal liver support have been described in this paper, with particular emphasis on modified single pass albumin dialysis (SPAD).1.

SPADS: Publisher Anonymization for DHT Storage
2010 IEEE Tenth International Conference on Peer-to-Peer Computing (P2P), 2010Many distributed applications, such as collaborative Web mapping, collaborative feedback and ranking, or bug reporting systems, rely on the aggregation of privacy-sensitive information gathered from human users. This information is typically aggregated at servers and later used as the basis for some collaborative service.

Crosstalk mapping in CMOS SPAD arrays
2016 46th European Solid-State Device Research Conference (ESSDERC), 2016Optical crosstalk is one of the main factors limiting the performance of Single-Photon Avalanche Diode (SPAD) arrays and Silicon Photomultipliers (SiPMs). In this paper, a set of crosstalk measurements on a CMOS SPAD pixel array with 50µm × 75µm pitch and 51.6% Fill Factor, designed for direct particle detection, is reported.

The antibacterial effect of SPAD.
Egyptian dental journal, 1992The antibacterial effect of SPAD, a root canal obturation paste containing paraformaldehyde, was examined and compared with that of calcium hydroxide apexification paste (Pulpdent). Both materials were either immediately placed in cultures containing streptococci group D, isolated from infected root canals, stored in an incubator for 3, 7 and 15 days ...
