Material Sensing & Instrumentation
MSI Time-Domain-Reflectometry (TDR) Structural-Health Monitoring probes the structural health of a composite part by propagating a fast electrical pulse along a distributed linear sensor which has been fabricated directly in the laminate. The sensor is formed from the native graphite fibers already used in composite manufacture, and constitutes zero defect. Fibers are patterned into a microwave waveguide geometry, or transmission line, and interrogated by a rapid pulse as shown below. Structural faults along the line cause distortions in waveguide geometry, producing reflected pulses similar to radar. Cracking, delamination, disbonds, moisture penetration, marcelling, and strain are all detected by propagation delay, for sensor lengths up to several meters.

SHF Communication Technologies AG
SHF’s microwave components are broadband devices suitable up to 110 GHz. Our SHF BIAS TEES are well known but perhaps a slight variation does suit your application even better. DIPLEXERS are bias tees with a certain bandwidth in the low frequency path to combine or separate high frequency and low frequency signals into or out of a single line. DC-FEEDERS are bias tees without the capacitor. Therefore, it provides slightly lower insertion loss in case it is connected to an AC-coupled device which already has a capacitor on its input. Based on our air line construction, these passive components provide resonance-free transmission over the entire operating range.

Acces I/O Products, Inc.
Many types of external computer equipment have a serial ports to communicate with host PCs. ACCES I/O has Communication Cards for all of the popular protocols you may find on this type of equipment (RS-232, RS-422 and RS-485), ranging from a single port to eight ports on a single card. There are also optically isolated versions of some of these cards to ensure effective data transmission on long communication lines, even in electrically noisy environments. Having optical isolation is like having data insurance.

Pickering Interfaces Ltd.
Each channel can support up to 0.3A and is rated to handle up to 100V between the wire pairs. The wire pairs have controlled transmission line impedance suited to most differential pair signaling systems, including fast CAN Bus interfaces and RS232. Each fault bus is capable of carrying 2A allowing multiple channels to be connected to the same fault condition. Additionally, each fault bus features a changeover relay to allow the user to connect alternative fault conditions to the fault buses.

60-984-001 -
Pickering Interfaces Ltd.
The 60-894 provides a simple an effective method of joining two LXI WTB bus cables together to extend the length of available cables. It is an ideal solution for cable extension where users need to experiment with different cabling solutions without having to totally replace the cables in the system. The 60-894 provides mating connectors for the WTB on each end connected together by a set of accurate differential transmission lines to avoid additional reflections on the cable. The 60-894 is entirely passive and is compatible with the LXI specification.

Since the rise time of IGBTs are in the range of a few tens of nanoseconds (between 50ns-200ns), even short cables between PWM motor drives and motors cause voltage doubling at the motor terminals due to Travelling Wave Phenomenon as in transmission lines. The insulation of motor windings are prone to failure due to high voltage spikes if necessary precautions are not sufficiently taken. RC Type Output Filter Modules reduce these high voltage spikes to protect motors by connecting to stator terminals.
