An onboard miniature data recorder from Diversified Technical Systems can be used to help flight test engineers capture physical signals in rugged conditions, including those involving unmanned vehicles.

DTS offers a Slice IP68 data acquisition system that works in IP68 conditions for dust and water, down to 20 meters for 10 hours. Slice modules (60 x 60 mm in size) stack to create the exact features and channels needed for testing, according to a July press release from DTS.

The modules can be embedded in or on testing locations, including the rotors on aircraft near the sensors. DTS said they are ideal for testing in non-pressurized environments, inclement weather or when quick altitude changes may create condensation on instruments.

Infosys positioned as a Leader in Gartner Magic Quadrant for IT Services for Communications Service Providers, Worldwide 2020

The Gartner Magic Quadrant evaluated 12 vendors and Infosys was recognized for its completeness of vision and ability to execute.
Infosys leverages its global partner ecosystem, CSP-dedicated studio, design tools, and 5G Living Labs to boost service delivery. Innovative solutions such as the ‘Infosys Cortex2’ are driving business value for CSPs.

Slice supports various sensors including bridge and IEPE transducers for measurements such as acceleration, displacement, strain, pressure, temperature, voltage and others. Three axis acclerometers are included in an Accel Slice. All the data is stored directly on 16GB internal flash memory.

According to a data sheet, primary power can be provided externally or with a PowerPack. The base slice of the system includes a microprocessor, memory and control circuits. Two software options are available to track sensor information. Communication is via USB.

While flight engineers may benefit, DTS says the Slice product can be used for testing in auto safety, amusement rides, biomechanics, parachute deployment, sports and safety equipment and acoustic measurements.
