Reconfigurable Hardware for Compressing Hyperspectral Image Data
Read More >>
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 ...Read More >>
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
Read More >>
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 ...Read More >>
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
Read More >>
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 ...Read More >>
