H.324

From Wikipedia, the free encyclopedia
 
H.324 is an ITU-T recommendation for voice, video and data transmission over regular analog phone lines. It uses a regular 33,600 bit/s modem for transmission, the H.263 codec for video encoding and G.723.1 for audio.
H.324 standard is formally known as Terminal for low bit-rate multimedia communication. H.324 covers the technical requirements for very low bit-rate multimedia telephone terminals operating over the General Switched Telephone Network (GSTN). H.324 terminals provide real-time video, audio, or data, or any combination, between two multimedia telephone terminals over a GSTN voice band network connection.
H.324 terminals offering audio communication shall support the G.723.1 audio codec. H.324 terminals offering video communication shall support the H.263 and H.261 video codecs. G.722.1 may be used for wideband audio applications. Annex G of H.324 specification defines usage of ISO/IEC 14496-1 (MPEG-4 Systems) generic capabilities in H.324 terminals. H.324/I terminals shall support interoperation with voice telephones using G.711 speech coding, if the connected network supports transmission and reception of G.711. Other modes such as G.722 audio may optionally be supported as well.[1]
H.324 was adapted by 3GPP to form 3G-324M.
It is for example used in the Vialta Beamer BM-80 Phone Video Station, the MINX system from Datapoint Corporation, and in several other videophones.

Airbus innovative payload to launch on Faraday-1 satellite & SDR in-orbit proving of disruptive technology

Airbus developed next generation retaskable software defined radio payload to be proven in space

Airbus’ newspace initiative Prometheus will see rapid in-orbit proving of disruptive technology


Stevenage, 01 July 2020 - An Airbus developed next generation retaskable software defined radio payload, Prometheus 1, will be launched on the Faraday-1 cubesat from New Zealand on 3 July. The Faraday-1 mission is part of In Space Missions Ltd’s in-orbit demonstration programme.

Prometheus 1 is a software defined radio, connected to a 400 MHz UHF antenna that can be reprogrammed in orbit. It will be able to survey radio spectrum usage across the world from orbit, detect radar tracking of the Faraday-1 satellite, and identify and locate search and rescue beacons. Airbus is working with the UK’s Defence Science and Technology Laboratory (DSTL) to foster greater partnerships between SMEs, government and Airbus on space.

Airbus Defence and Space in the UK created the self funded Prometheus programme to enable the rapid development of agile and innovative payloads using disruptive technology to offer significant capability to customers. Building on Airbus’ proven track record of working with SMEs to create novel capability and prove concepts, the Prometheus programme developed the payload for Faraday-1 in under three months.

Richard Franklin, Managing Director of Airbus Defence and Space UK said: “By working with SMEs we are able to take advantage of their specialist capabilities and agility to develop new technologies and services for customers. Once Prometheus 1 is proven in orbit we will use it to de-risk future services and in life support solutions, working hand in hand with our SME partners. Future UK Government defence needs can be best served by the partnership approach we have pioneered at Airbus on Skynet 5, actively engaging with SMEs and developing new technologies and service solutions to prove concepts before delivering them to customers.”

Prometheus 1 will prove passive radio frequency sensing in orbit, enabling the technology to be incorporated on future missions where hostile tracking of sovereign spacecraft is likely or possible.

The Airbus newspace team is championing the Prometheus programme and a second mission is already in development, which will be cubesats with RF and optical sensors, and features inter satellite links. Prometheus 2 is due for launch in the second half of 2021.

Airbus is working with In Space Missions to offer ‘Space as a Service’ access to capability for DSTL to get involved in experiments with assets in orbit.

RIO FLEX Software Defined Radio SIGINT SYSTEM / Autonomously System / Drone System

RIO FLEX SIGINT SYSTEM

Shared Link: https://www2.l3t.com/mid/pdf/data_sheets/Rio_Flex_SIGINT_System.pdf

Rio Flex is a modular, scalable signals intelligence (SIGINT) processing system designed for a variety of manned, unmanned airborne or ground collection platforms.





OVERVIEW

Rio Flex is the latest generation of Rio technology, leveraging over 50 years of investment in advanced SIGINT software-defined radio (SDR) systems to build solutions using readily available modular COTS components. It is scalable in size, weight, and power (SWaP) and it can be fitted to platforms of various sizes and shapes. Rio Flex uses the same modular SIGINT software as other Rio systems to provide proven capabilities for a wide variety of platforms and combines it with the flexibility of modular hardware. This approach enables faster time-to-market for putting cutting-edge SIGINT capabilities in the hands of the warfighters. Rio software modules for search, detection, classification, recording, and precision geolocation are available, along with an internet browser-based real-time operator interface. Rio Flex can also operate autonomously using Rio Virtual Op.





RIO FLEX WORKSTATION DISPLAYS

Rio Flex uses a thin client graphical user interface — any workstation can run Rio Flex using a web browser.

Machine learning assistive rapid, label-free molecular phenotyping of blood with two-dimensional NMR correlational spectroscopy using open source code software-defined-radio

Shared Link: https://www.biorxiv.org/content/10.1101/2020.06.20.162974v1.full


Abstract

Translation of the findings in basic science and clinical research into routine practice is hampered by large variations in human phenotype. Developments in genotyping and phenotyping, such as proteomics and lipidomics, are beginning to address these limitations. In this work, we developed a new methodology for rapid, label-free molecular phenotyping of biological fluids (e.g., blood) by exploiting the recent advances in fast and highly efficient multidimensional inverse Laplace decomposition technique. We demonstrated that using two-dimensional T1-T2 correlational spectroscopy on a single drop of blood (<5 μL), highly time– and patient–specific ‘molecular fingerprint’ can be obtained in minutes. Machine learning techniques were introduced to transform the NMR correlational map into user-friendly information for point-of-care disease diagnostic. The clinical utilities of this technique were demonstrated through the direct analysis of human whole blood in various physiological (e.g., oxygenated/deoxygenated states) and pathological (e.g., blood oxidation, hemoglobinopathies) conditions.
