Many observers believe that the urban canyon and indoor problem will be progressed, maybe even fixed, over the next few years. The candidate technologies are already in place and significant progress is already being made. This revolution has already started with assisted-GPS, where the

GSS5700

almanac and ephemeris (precise satellite location) data is uploaded to reduce the search window, resulting in quicker Time To First Fix (TTFF) and the ability to acquire lower power signals, including limited ability to navigate indoors. At the user level, we are seeing new applications, falling prices and better performance. GNSS is appearing everywhere.

Wi-Fi positioning is, however, rapidly gaining acceptance as a complement and supplement to GNSS positioning for indoor environments. Wi-Fi hotspots are prevalent in the very areas where GNSS starts to struggle and many 'smart' devices are already equipped with Wi-Fi technology that can support positioning applications. Numerous service providers are offering the essential databases that enable the overall positioning capability. learn more

Luna Technologies' Optical Distributed Sensor Interrogator (ODiSI) instrument saves time and cost while adding a new dimension to sensing measurements with its unprecedented

spatial resolution. Using swept-wavelength interferometry, the ODiSI interrogates thousands of sensing locations on a single optical fiber

simultaneously.

Reduce cost and better characterize your system by instrumenting many sensing locations with a single, inexpensive optical fiber.

With sensors suitable for surface bonding or embedding in composites, this technology can accomplish your objectives either by direct integration during manufacturing or later installation.

Structural monitoring for naval, aerospace and civil structures:

Luna's fully distributed sensing technology yields dynamic capture of the entire strain field.

• Conformal deformation
• Composite damage assessment
• Bonded joint integrity monitoring

• Fuel cells
• Concrete cure temperature monitoring in large structures
• Industrial chemical process monitoring
• High temperature capabilities - up to 300°C

Introduction 

Ask any manufacturer that deals with production line electrical safety testing and they will tell you that the two most commonly performed tests are the Hipot test and some form of ground integrity test (usually referred to as a Ground Continuity test or a Ground Bond test). This is because most standards require these tests to be performed as 100% production line tests on every product before shipment. While traditional safety testers perform only one type of test, more advanced testers are capable of performing different types of tests in sequence, increasing efficiency on the production line. Associated Research offers electrical safety testing options for a variety of requirements and budgets.

The FixTreme is designed to provide a cost effective, high performance thermal enclosure for your device under test (DUT).

Available in 2 designs (hood or clamshell), FixTreme thermal enclosures come in a

variety of footprints to fit your requirements. All units are lightweight, portable enclosures ideal for "at temperature" functional testing, burn-in, or as a standalone thermal functional tester.

The enclosures are configured to accommodate testing over a wide    temperature range. The FixTreme Series provides a moisture and static free thermal test environment with precise DUT temperature control using thermocouples or RTDs.
