“…For example, during flooding or heavy rain, wires may become wet and thus provide poor signals, while wireless communication can be made to be more immune to water damage. As presented in Figure 8, the wireless communication hardware development can leverage our previous R&D works in which we have demonstrated a wideband cognitive radio transceiver and wireless channel emulator through a National Science Foundation (NSF)-funded project [10], a radiation-hard 6-12 GHz 00.37pS RMS jitter wideband LC-VCO phase-locked loop (PLL) [11], and radiationtolerant application specific integrated circuits (ASICs) for CERN's large hadron collider (LHC) detectors [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27]. In developing the wireless transceiver, commercial off-the-shelf (COTS) radiationhardened components based on Silicon-on-Sapphire (SOS) and Silicon on Insulator (SOI) technology should be utilized.…”

Natural disasters (earthquakes, hurricanes, tornadoes. and floods) or man-made disasters or accidents (missile/aircraft impacts, fires. and explosions) lead to substantial damage on critical infrastructures and communities and have social, economic, and environmental consequences. As the safety of civil infrastructures is critically important, effective structural health monitoring (SHM) systems of infrastructures should be developed to avoid and mitigate the risks caused by various types of hazards. Carbon Nanofiber Aggregates (CNFAs) developed at the University of Houston are piezoelectric aggregates that can respond uniquely to different multi-hazards. This unique response makes this a sensor capable of being used in the Structural Health Monitoring (SHM) of civil infrastructures in each of the multi-hazards. This paper explains how CNFAs can be used for multi-hazard monitoring and discusses the ultra-low noise, high sensitivity of CNFA sensor electrical interfaces, radiation-tolerant wired and wireless communication capabilities of the CNFA sensor which leads to the very possible development of the wireless CNFAs' real-time SHM system for sustaining resilience of civil infrastructures to multi-hazards.

This paper presents several component prototypes towards a low-latency, small-form-factor optical link designed for the ATLAS Liquid Argon Calorimeter Phase-I trigger upgrade. A prototype of the custom-made dual-channel optical transmitter module, the Miniature optical Transmitter (MTx), with separate transmitter optical sub-assemblies (TOSAs) has been demonstrated at data rates up to 8 Gbps per channel. A Vertical-Cavity Surface-Emitting Laser (VCSEL) driver ASIC has been developed and is used in the current MTx prototypes. A serializer ASIC prototype, operating at up to 8 Gbps per channel, has been designed and tested. A low-latency, low-overhead encoder ASIC prototype has been designed and tested. The latency of the whole link, including the transmitter latency and the receiver latency but not the latency of the fiber, is estimated to be less than 57.9 ns. The size of the MTx is 45 mm × 15 mm × 6 mm. I.

“…Post-layout simulations show that the power consumption of the ASIC is about 200 mW. In the future, the encoder will be integrated in an ASIC together with an 8:1 serializer [5].…”

“…For a line code used in LHC experiments, the encoder is typically implemented in a radiation-tolerant Application-Specific Integrated Circuit (ASIC), whereas the decoder can be implemented in a commercial Field-Programmable Gate Array (FPGA). We have designed and tested two serializer ASIC prototypes [4][5] in a commercial 0.25-µm Silicon-on-Sapphire (SoS) CMOS technology for the ATLAS Liquid Argon Calorimeter Phase-I trigger upgrade [6]. The SoS CMOS technology is chosen because it is immune to the single event latchup and has smaller single event upset cross section than equivalent bulk technologies.…”

We propose a line code that has fast resynchronization capability and low latency. Both the encoder and decoder have been implemented in FPGAs. The encoder has also been implemented in an ASIC. The latency of the whole optical link (not including the optical fiber) is estimated to be less than 73.9 ns. In the case of radiation-induced link synchronization loss, the decoder can recover the synchronization in 25 ns. The line code will be used in the ATLAS liquid argon calorimeter Phase-I trigger upgrade and can also be potentially used in other LHC experiments.
