Oil Pipeline Fault Detection System Determines Material Permittivity at Microwave Frequencies

Researching fault location techniques for the oil industry requires data on the complex permittivity of the polyamide Rilsan at microwave frequencies. Rilsan is a vital material used in oil pipe construction. Currently there is no published data for the complex permittivity of Rilsan. The task for this project was to develop an accurate method to measure the complex permittivity of Rilsan to gain an understanding of the dielectric relaxations that occur within it. A fast, accurate method was developed using a vector network analyzer (VNA) and rectangular waveguide.

From VME to VPX

Sequestration, defense reform and cost constraints are driving a new paradigm in the defense industry, where leveraging existing technologies is no longer optional, but required. This is especially true as we migrate from VME to VPX-based embedded computing.

MicroTCA Ecosystem

VadaTech (Henderson, NV) has released a complete ecosystem of boards and chassis in the MicroTCA architecture that is conduction-cooled. Designed for rugged applications, the products include air transport racks (ATR), MicroTCA carrier hubs (MCH), power modules, and advanced mezzanine cards. Compliant to MicroTCA.3 (Hardened Conduction-Cooled MicroTCA) specification, the boards and chassis come in various sizes and formats.

The MCH, which acts as a shelf controller, features a 400 MHz RISC CPU for high performance and low latency. The power modules provide true hot- swappability in a dual 10-36V input and outputs of up to 800W. They also have dual Intelligent Platform Management Interface (IPMI) and two banks of 256K flash for redundancy. Several of VadaTech’s advanced mezzanine cards (AMCs) are in the conduction-cooled format. The company is also able to modify standard AMCs to ruggedized versions with wedge locks.

XMC Controller/Adapter

Technobox, Inc. (West Berlin, NJ) has introduced a new SATA-based storage solution in its 6183 Dual CFast XMC Adapter. The 6183 accommodates two CFast devices – either the Type 1 or 2 – with one affixed to an on-board site and the other removable via the front panel port. Data movement between each CFast device and the internal 1X PCIe bus is controlled by a Silicon Image Sil3132 bridge. The bridge supports two SATA Gen2 interfaces at 3.0 GBytes/s.

On-board BIOS, loaded in flash memory, provides boot up configuration for the Sil3132. The bridge retrieves the stored configuration data via an I2C interface. Two LEDs on the front panel provide activity status for the front panel and onboard CFast cards. Another four LEDs on the card give an indication of activity for each device.

A retention mechanism is included to prevent accidental removal of the front panel device. The retainer also functions as an interlock for the 6183 hot swap feature. .

DDS Function Generator

Saelig Company, Inc. (Fairport, NY) has introduced the TG1006 - a DDS-based 1mHz to 10MHz function generator that, unlike other digital generators, can be operated over any frequency range using analog control in addition to numeric or spin-wheel frequency entry. The quasi-analog frequency control can rapidly sweep the frequency between preset limits, which is difficult to do with most digital function generators.

The TG1006 Function Generator can produce waveforms between 0.001Hz and 10MHz with a resolution of six digits, and with a one-year stability of better than 10ppm. Up to ten frequencies can also be stored in memory for preset test procedures. The output amplitude is variable between 5mV and 20V pk-pk from a source impedance of 50 ohms or 600 ohms. The LCD display shows frequency and amplitude or offset simultaneously. For accurate frequency selection, precise frequencies can be entered directly from the numeric keypad in Hz, kHz or MHz.
