“…Slow (milliseconds and microseconds) Optical Switches: Micro-electrical mechanical switches (MEMS) switches are micrometer-scale devices that rely on mechanical moving micro-mirrors to switch the optical signal from input ports to output ports [69]. An array of N2 micro-mirrors is needed to build a N×N direct switching MEMS switch.…”

Relying on the flexible-access interconnects to the scalable storage and compute resources, data centers deliver critical communications connectivity among numerous servers to support the housed applications and services. To provide the high-speeds and long-distance communications, the data centers have turned to fiber interconnections. With the stringently increased traffic volume, the data centers are then expected to further deploy the optical switches into the systems infrastructure to implement the full optical switching. This paper first summarizes the topologies and traffic characteristics in data centers and analyzes the reasons and importance of moving to optical switching. Recent techniques related to the optical switching, and main challenges limiting the practical deployments of optical switches in data centers are also summarized and reported.

“…Therefore, the inertial switch has the great advantage of acting like an open circuit when not active in the OFF state; it consumes power only when the threshold is exceeded (near zero power consumption). With the emergence of the Internet of Things (IoT), tremendous amounts of inertial sensors are increasingly in demand to meet the market’s needs 6 – 8 . In most cases, inertial switches are designed to have a single threshold which can only provide binary “ON/OFF’ information 9 – 15 .…”

This paper presents a tunable multi-threshold micro-electromechanical inertial switch with adjustable threshold capability. The demonstrated device combines the advantages of accelerometers in providing quantitative acceleration measurements and g-threshold switches in saving power when in the inactive state upon experiencing acceleration below the thresholds. The designed proof-of-concept device with two thresholds consists of a cantilever microbeam and two stationary electrodes placed at different positions in the sensing direction. The adjustable threshold capability and the effect of the shock duration on the threshold acceleration are analytically investigated using a nonlinear beam model. Results are shown for the relationships among the applied bias voltage, the duration of shock impact, and the tunable threshold. The fabricated prototypes are tested using a shock-table system. The analytical results agree with the experimental results. The designed device concept is very promising for the classification of the shock and impact loads in transportation and healthcare applications.

“…With the development of MEMS, researchers have put forward various MEMS inertial switches with high threshold acceleration in fuze, aerospace and other fields over the last decades [5][6][7]. On account of the impact acceleration can be up to ten thousand g, Cao et al [8] proposed a single circular mass for universal sensitivity to guarantee the survivability of high-g inertial switch.…”

Inertial impact switch is a widely used inertial force recognition element in electromechanical trigger fuze of missiles, rockets and artillery shells. In this paper, the impact responses of inertial switch are investigated with abundant acceleration loads through the dynamics analysis. Based on the Machete hammer experiment, the accuracy of the dynamics model is verified with a very small error. The systematic dynamic analysis shows that the contact time of impact proceeding keeps continuously increasing with greater pulse width and acceleration load. On the other hand, the threshold of switch decreases alone with the pulse time. To improve the performance index of the inertial impact switch, a spherical structure model is proposed. Surprisingly, a significant improvement of the contact time is discovered comparing with the cylindrical structural model. The proposed new structure will provide important technical reference for the practical application of devices in fuze technology field.
