Reconfigurable Hardware for Compressing Hyperspectral Image Data
Multiple hardware cores can be combined to increase throughput.
High-speed, low-power, reconfigurable
electronic hardware has been developed
to implement ICER-3D, an algorithm for
compressing hyperspectral-image data.
The algorithm and parts thereof have
been the topics of several NASA Tech Briefs
articles, including “Context Modeler for
Wavelet Compression ...

High-Speed Ring Bus
The high-speed ring bus at the Jet
Propulsion Laboratory (JPL) allows for
future growth trends in spacecraft seen
with future scientific missions. This innovation
constitutes an enhancement of the
1393 bus as documented in the Institute of
Electrical and Electronics Engineers
(IEEE) 1393-1999 standard for a spaceborne
fiber-optic data bus. It ...

Spatio-Temporal Equalizer for a Receiving-Antenna Feed Array
Suppression of multipath effects and robust pointing would be achieved.
A spatio-temporal equalizer has been
conceived as an improved means of
suppressing multipath effects in the
reception of aeronautical telemetry signals,
and may be adaptable to radar
and aeronautical communication
applications as well. This equalizer
would be an ...

Lunar Dust-Tolerant Electrical Connector
An electrical connector was developed
that is tolerant of the presence of
lunar dust. Novel features of the connector
include the use of a permeable
membrane to act both as a dust barrier
and as a wiper to limit the amount of
dust that makes its way into the internal
...

Nanoionics-Based Switches for Radio-Frequency Applications
These switches might supplant semiconductor and MEMS switches in some applications.
Nanoionics-based devices have shown
promise as alternatives to microelectro-mechanical
systems (MEMS) and semiconductor
diode devices for switching
radio-frequency (RF) signals in diverse
systems. Examples of systems that utilize
RF switches include phase shifters for
electronically steerable phased-array
