Teledyne Defense Electronics
Teledyne e2v HiRel Microdosimeter is a compact hybrid microcircuit which directly measures total ionizing dose (TID) absorbed by an internal silicon test mass. The test mass simulates silicon die of integrated circuits on-board a host spacecraft in critical mission payloads and subsystems. By accurately measuring the energy absorbed from electrons, protons, and gamma rays, an estimate of the dose absorbed by other electronic devices on the same vehicle can be made. The Microdosimeter can operate from a wide range of input voltages. The accumulated dose is presented to three dc linear outputs and one pseudo-logarithmic output giving a dose resolution of 14 µrads and a measurement range up to 40 krads. These outputs are intended to be directly connected to most analog-to-digital converters (ADCs) or spacecraft housekeeping analog inputs (0-5 V range), which makes minimal demands on the host vehicle. The Microdosimeter incorporates a test function to allow electrical testing of the hybrid without the need for a radiation source.

ERAVANT
In radio communication, an omnidirectional antenna is a class of antenna which radiates equal radio power in all directions perpendicular to an axis (azimuthal directions), with power varying with angle to the axis (elevation angle), declining to zero on the axis.[1][2] When graphed in three dimensions (see graph) this radiation pattern is often described as doughnut-shaped. Note that this is different from an isotropic antenna, which radiates equal power in all directions, having a spherical radiation pattern. Omnidirectional antennas oriented vertically are widely used for nondirectional antennas on the surface of the Earth because they radiate equally in all horizontal directions, while the power radiated drops off with elevation angle so little radio energy is aimed into the sky or down toward the earth and wasted. Omnidirectional antennas are widely used for radio broadcasting antennas, and in mobile devices that use radio such as cell phones, FM radios, walkie-talkies, wireless computer networks, cordless phones, GPS, as well as for base stations that communicate with mobile radios, such as police and taxi dispatchers and aircraft communications.

Measurements International Ltd.
The measurement of electric power and energy at high voltages and currents at low power factors is becoming increasingly important economically as a way to reduce costs in an ever-growing industrial economy. Today the transformer purchaser subjects the transformer manufacturer to an economic penalty for losses that occur in load and no-load conditions. To keep these penalties as low as possible, it is important that the manufacturer accurately measure these losses. Failure to do so can result in the manufacturer losing important contract awards to their competitors who may be utilizing a more accurate system. Using “State of the Art” proven two-stage-currentcomparator technology, the AccuLoss™ Series of transformer loss measurement systems is designed to meet the needs of today’s transformer manufacturer by providing the most accurate power loss measurement system in the world. Designed for power frequency testing and calibration, the AccuLoss™ system can be used for testing small, medium and large power transformers as well as motors and turbines up to 400 Hz. The system is also ideal for R&D facilities. The AccuLoss™ system can also be used to measure losses in single and three phase reactors.

Infinite Industrial Informatics Lt
Sigfox is a communication protocol that is used to read data from sensors through a fixed network of base stations. It works like a low cost “SMS” service. As an end-user, you only need to buy a subscription to connect to the data network operated by SIGFOX. Sigfox employs a proprietary Ultra Narrow Band (UNB) radio technology that enables communication using the Industrial, Scientific and Medical ISM radio band, which uses 868MHz in Europe and 902MHz in the US. It has the advantage of covering larger areas than other fixed local systems.The overall Sigfox network topology has been designed to provide a scalable, high-capacity network, with very low energy consumption, while maintaining a simple and easy to rollout star-based cell infrastructure. The density of the cells in the Sigfox network is based on an average range of about 30-50km in rural areas and in urban areas, where there are usually more obstructions and noise is greater, the range may be reduced to between 3 and 10km.According to the latest numbers, Sigfox has a nationwide live coverage in 6 countries and in 14 other countries it is deploying and rolling out ts network. By end 2018, the ambition is to cover 60 markets.

ADLINK Technology Inc.
The SMARC ("Smart Mobility ARChitecture") is a versatile small form factor computer Module definition targeting applications that require low power, low costs, and high performance. The Modules will typically use ARM SOCs similar or the same as those used in many familiar devices such as tablet computers and smart phones. Alternative low power SOCs and CPUs, such as tablet oriented X86 devices and other RISC CPUs may be used as well. The Module power envelope is typically under 6W. The Modules are used as building blocks for portable and stationary embedded systems. The core CPU and support circuits, including DRAM, boot flash, power sequencing, CPU power supplies, GBE and a single channel LVDS display transmitter are concentrated on the Module. The Modules are used with application specific Carrier Boards that implement other features such as audio CODECs, touch controllers, wireless devices, etc. The modular approach allows scalability, fast time to market and upgradability while still maintaining low costs, low power and small physical size. To stress on its low power consumption feature, ADLINK has named SMARC products as LEC (Low Energy Computer on module) series.

Thales SESO, SAS
For more than 40 years, Thales has delivered high accuracy optics for ground-based Astronomy all around the world. These optics range from single, but challenging, unmounted optical components up to fully integrated opto-mechanical systems. Our design heritage and past experience in this field cover the design, manufacture and AIT activities of many optics and sub-assemblies used in Telescope instrumentation, such as focal plane assemblies as well as the direct production of telescope mirrors themselves. Several major achievements of Thales ground-based Astronomy products were the Optical wide field corrector for the Dark Energy Survey (lien), the Reference Body for future Deformable Secondary Mirror of the VLT (lien) and different challenging spectrograph optics (Collimator and Cameras) for different Observatories (lien). One advantage Thales has with this activity is that most part of the manufacturing steps involved (i.e. opto-mechanical design, milling/grinding, lightening, polishing and coating) are directly under our control in our own facility. Our current capabilities for the production of optics for ground-based Astronomy are from a few centimeters size up to 2 meters. Thanks to the continuous efforts in R& D and investments into new production machines, Thales is now ready for future industrial challenges including the optical production of some key elements of the E-ELT, GMT and TMT programs.

RMO-TW Series -
IBEKO Power AB
RMO-TW series is perfect for winding resistance measurements of inductive objects. It is ideal for testing transformer windings (power transformers, distribution, autotransformers) and for on-load tap changer verification. In addition, any RMO-TW transformer ohmmeter & tap changer analyzer can also perform transformer demagnetization.The series contains 4 models, with maximal test currents from 10 A (RMO10TW) to 50 A (RMO50TW). They are fitted in a portable and lightweight metal housing.All transformer ohmmeters from RMO-TW series generate a true DC ripple-free current with automatically regulated measurement and discharging circuit. The injection of current and discharge of energy from the test object are automatically regulated.Three independent channels enable testing of three windings in series. Consequently, this enables measurements of winding resistance in every tap position of an on-load tap changer without discharging between the tests.DV-Win software enables control and observation of the test process, as well as saving and analyzing the results on a PC. It provides a test report, arranged in a selectable form as an Excel spreadsheet, PDF, Word, or ASCII format. Additionally, DV-Win measures and calculates the OLTC transition time, the ripple and the winding resistance for each tap changing operation. The software can also perform the calculations necessary for the “Heat Run” test. Finally, a user can export all results in the form of a report.
