Instrumentation
Sensing, Data Acquisition and Telemetry
Crossfield
is developing wireless instruments and data acquisition
platforms that acquire sensor data in harsh environments
(e.g. high temperature, high acceleration) or under
low-power operational constraints. Emerging technologies
under investigation include power scavenging techniques for
applications where batteries are not feasible and conformal
circuit technologies for space-constrained applications.
Liquid Crystal Polymer (LCP) material is being used to
implement embedded passive RF devices and to serve as a
carrier for surface-mounted semiconductors. Crossfield is
working with MIT to develop Organic Thin Film Transistors
(OTFTs) for ultra-low-cost sensor arrays.
Software-Defined Radios (SDRs) and Digital
Receivers
Crossfield has developed direct-conversion
digital receiver designs that capture data at 2 GSPS with
14 bits of resolution and write the signal data directly
into computer memory. The SDR features novel signal
analysis techniques to extract sub-Hertz resolution signals
using a very-large-N Fast Fourier Transform.
Intelligent Wireless Controllers for Solid State
Lighting (SSL)
Crossfield's green technologies reduce
the amount of energy required to light an area using
Intelligent Wireless Controllers (IWCs) and White LEDs.
IWCs put light where it's needed, when it's needed, to
conserve energy.
