Liquid Instruments Lança Moku:Pro – Uma Plataforma de Instrumentação de Alto Desempenho Definida por Software para Engenheiros e Cientistas

Nova arquitetura proporciona nove instrumentos com capacidades de medição em tempo real para laboratórios de pesquisa

CANBERRA, Austrália e SAN DIEGO, June 23, 2021 (GLOBE NEWSWIRE) — A Liquid Instruments, empresa inovadora em instrumentação definida por software de precisão, anunciou hoje o lançamento do Moku:Pro, uma plataforma de alto desempenho para laboratórios de engenharia e pesquisa.

O Moku:Pro acelera a transição do hardware tradicional de teste e medição de função fixa para uma abordagem flexível com base em field-programmable gate array (matriz de portas programáveis em campo – FPGA), tornando os instrumentos de alta qualidade acessíveis em uma plataforma integrada e atualizável por software.MokuPro-Digital

“Os pesquisadores em engenharia e física enfrentam exigências em constante evolução – com mudanças ocorrendo em um tempo muito menor do que a vida útil do equipamento de teste”, disse Daniel Shaddock, CEO da Liquid Instruments. “A arquitetura de hardware habilitado por software do Moku:Pro permite que ele evolua juntamente com suas aplicações, o que não é possível com equipamentos de teste convencionais.”

O Moku:Pro hospeda nove instrumentos potentes, incluindo osciloscópio, amplificador de bloqueio, controlador PID, fasímetro, gerador de forma de onda arbitrária, registrador de dados, analisador de espectro, analisador de resposta de frequência e gerador de forma de onda para garantir que os pesquisadores tenham a instrumentação necessária para caracterizar rapidamente sua configuração e dimensionar seus experimentos. A plataforma foi projetada para atender às necessidades dos pesquisadores em uma variedade de campos, do aeroespacial ao semicondutor. O conjunto de instrumentos do Moku:Pro é particularmente adequado para aplicações fotônicas, incluindo espectroscopia, microscopia, metrologia, detecção de ondas gravitacionais, estabilização a laser ativa e computação quântica.

“A computação quântica aumenta os limites do desempenho da eletrônica, óptica e processamento flexível de sinais em tempo real. A instrumentação definida por software é o futuro dos sistemas de teste e medição para computação quântica”, disse Andrew Horsley, CEO e cofundador da Quantum Brilliance, uma empresa de computação quântica completa que trabalha com tecnologia de diamante em temperatura ambiente.  “O Moku:Pro é a base de um laboratório e uma das ferramentas fotônicas mais versáteis que já vimos.”

Instrumentação na Era Moderna
O Moku:Pro leva o teste e a medição para a era moderna, permitindo que engenheiros e pesquisadores alternem dinamicamente entre os instrumentos em vez de precisarem de vários dispositivos autônomos.  A tecnologia avançada de mistura de ADC garante que cada instrumento possa funcionar com sensibilidade ideal desde a FR até as frequências acústicas sem comprometer o desempenho da flexibilidade. A conectividade total via Wi-Fi, Ethernet e USB-C garante a configuração sem problemas padrão da indústria.MokuPro-Digital 2

Um benefício fundamental da instrumentação definida por software é que ela melhora ao longo do tempo. O Moku:Pro pode ser atualizado aereamente, podendo fornecer especificações melhoradas, novos instrumentos ou recursos totalmente novos. Esses benefícios devem estar disponíveis para os usuários em setembro, quando a Liquid Instruments pretende lançar um recurso que dará ao Moku:Pro a capacidade de executar vários instrumentos em conjunto e trocar automaticamente os instrumentos. Neste modo multi-instrumento, os instrumentos podem ser combinados e conectados para formar dutos sofisticados de processamento de sinal. Em setembro também estamos planejando lançar nova ferramenta com base na nuvem que permitirá que os usuários programem diretamente o FPGA do Moku:Pro. Com essa capacidade, os usuários poderão implementar algoritmos de processamento de sinal exclusivos e criar seus próprios instrumentos personalizados, ampliando ainda mais a lacuna com o hardware convencional.

Especificações do Moku:Pro

  • 4 entradas e saídas analógicas
  • Entrada ADC combinada (10 bits+18 bits) para aplicações de baixo ruído e alta largura de banda
  • Taxa de amostragem de 5 GSa/s (1 canal), 1,25 GSa/s (4 canais)
  • 9 instrumentos integrados, incluindo um amplificador de bloqueio DC-600 MHz
  • SSD de 120 GB para armazenamento a bordo de alta velocidade

Liquid Instruments lance Moku:Pro, une plateforme d’instrumentation définie par logiciel à hautes performances destinée aux ingénieurs et aux scientifiques

La nouvelle architecture fournit neuf instruments avec des capacités de mesure en temps réel aux laboratoires de recherche

CANBERRA, Australie et SAN DIEGO, 23 juin 2021 (GLOBE NEWSWIRE) — Liquid Instruments, un innovateur spécialisé dans les instruments de précision définis par logiciel, a présenté aujourd’hui Moku:Pro, une plateforme de haute performance pour les laboratoires d’ingénierie et de recherche.

Moku:Pro accélère la transition du matériel de mesure et de test à fonction fixe traditionnel vers une approche flexible basée sur les FPGA (Field Programmable Gate Arrays ou réseaux logiques programmables) en rendant les instruments de haute qualité accessibles au sein d’une plateforme intégrée évolutive par logiciel.

« Les chercheurs en ingénierie et physique font face à des exigences en constante évolution, avec des changements survenant selon des délais beaucoup plus courts que la durée de vie des équipements de test », a déclaré Daniel Shaddock, PDG de Liquid Instruments. « L’architecture matérielle compatible logiciel de Moku:Pro lui permet d’évoluer en même temps que vos applications, ce qui est tout simplement impossible avec les équipements de test conventionnels. »MokuPro-Digital

Moku:Pro contient neuf instruments puissants, dont un oscilloscope, un amplificateur à détection synchrone, un régulateur PID, un phasemètre, un générateur de forme d’onde arbitraire, un enregistreur de données, un analyseur de spectre, un analyseur de courbes de fréquence et un générateur d’onde pour s’assurer que les chercheurs disposent des instruments dont ils ont besoin pour caractériser et adapter rapidement leurs expériences. La plateforme a été conçue pour répondre aux besoins des chercheurs dans divers domaines, de l’aéronautique aux semi-conducteurs. La suite d’instruments de Moku:Pro est particulièrement adaptée aux applications photoniques, y compris la spectroscopie, la microscopie, la métrologie, la détection des ondes gravitationnelles, la stabilisation laser active et l’informatique quantique.

« L’informatique quantique repousse les limites de performance de l’électronique, de l’optique et du traitement flexible des signaux en temps réel. Nous considérons l’instrumentation définie par logiciel comme l’avenir des systèmes de test et de mesure pour l’informatique quantique », a déclaré Andrew Horsley, PDG et cofondateur de Quantum Brilliance, une société spécialisée dans l’informatique quantique full-stack travaillant sur la technologie des diamants à température ambiante.« Moku:Pro est un cheval de bataille du laboratoire et l’un des outils photoniques les plus polyvalents que nous ayons vus. »

Intégrer l’instrumentation à l’ère moderne
Moku:Pro fait entrer les tests et les mesures dans l’ère moderne, permettant aux ingénieurs et aux chercheurs de basculer dynamiquement entre les instruments plutôt que d’avoir besoin de plusieurs appareils autonomes. La technologie avancée de mélange ADC garantit que chaque instrument peut fonctionner avec une sensibilité optimale des fréquences RF aux fréquences acoustiques sans compromettre les performances de flexibilité. La connectivité complète via Wi-Fi, Ethernet et USB-C garantit une configuration standard et sans tracas.MokuPro-Digital 2

L’un des principaux avantages de l’instrumentation définie par logiciel est qu’elle s’améliore au fil du temps. Moku:Pro peut recevoir des mises à jour par liaison radio pour fournir des spécifications améliorées, de nouveaux instruments ou des capacités entièrement nouvelles. Les utilisateurs peuvent s’attendre à voir ces avantages dès le mois de septembre lorsque Liquid Instruments prévoit de lancer une fonctionnalité qui donnera à Moku:Pro la possibilité d’exécuter plusieurs instruments conjointement les uns avec les autres et les instruments échangeables à chaud à l’intérieur et à l’extérieur. Dans ce mode multi-instruments, les instruments peuvent être combinés et connectés pour former des pipelines sophistiqués de traitement des signaux. En septembre, la sortie d’un nouvel outil basé sur le cloud qui permettra aux utilisateurs de programmer directement le FPGA de Moku:Pro est également prévue. Grâce à cette capacité, les utilisateurs peuvent mettre en œuvre des algorithmes de traitement de signal uniques et créer leurs propres instruments personnalisés, ce qui permettra d’élargir davantage l’écart avec le matériel conventionnel.

Health Officials: Blast Kills Dozens in Tigray Market

A bomb blast killed dozens of people Tuesday at a market in Ethiopia’s Tigray region, as new fighting flared up in areas outside the regional capital, Mekelle.

The bomb went off in the town of Togoga west of Mekelle at about 1 p.m. local time. There were conflicting reports on whether the blast was the result of a plane dropping a bomb or artillery shells hitting the market.

Local medical officials that at least 43 people were killed, with dozens of others wounded.

Berhan Ghebrehiwet, who sells coffee for a living, said her hand was wounded during the attack.

“First they bombed the market and later they continue bombing the houses. My hand was injured from the bombing. I am suffering a lot and it is causing me great pain,” she told a reporter for VOA’s Horn of Africa Service at Hyder Hospital in Mekelle.

Health workers said Ethiopian soldiers blocked ambulances from reaching the scene of the attack.

Negasi Berhane, a Mekelle resident who suffered leg injuries in the attack, said he saw three people die in front of him, with many others left to suffer.

Ambulance driver Kahsu Tsegay told VOA he unsuccessfully tried five times to transport injured civilians to the hospital. The driver said he was barred from transporting wounded people on the grounds they had tried to help Tigray People's Liberation Front (TPLF) fighters.

Reuters news agency says an Ethiopian military spokesman, Colonel Getnet Adane, denied the military was blocking ambulances.

Later Wednesday, the International Committee of the Red Cross (ICRC) said it helped the Ethiopian Red Cross Society and other parties evacuate wounded people from Togoga and transport them to a hospital in Mekelle.

"We cannot stress enough how vital it is for the medical mission to be respected and protected at all times," ICRC official Nicolas von Arx said in a statement.

The U.S. State Department released a statement Wednesday, saying, “We strongly condemn this reprehensible act.” It said it was "gravely concerned" by the reports of the airstrike on the market.

State Department spokesman Ned Price urged Ethiopian authorities to "ensure full and unhindered medical access to the victims immediately."

Ethiopian defense forces commander General Berhanu Jula denied the military attacked the market. The general said the attack was targeting an armed group, not civilians.

Asked if he saw armed people during the bombing, Mekelle resident Negasi said he only saw civilians.

On Tuesday, residents said new fighting had erupted elsewhere in Tigray. Residents said TPLF fighters had entered towns north of the capital, only to withdraw within hours.

Tigray has been embroiled in conflict since November, when the Ethiopian military launched an offensive to oust the ruling TPLF. Eritrea’s military has been helping Ethiopian troops battle the TPLF in the ongoing dispute.

Thousands of people have been killed and some 2 million others have fled their homes to escape the violence since fighting erupted.

After Cameroon Government Ban from Western Regions, MSF Says Thousands Lack Healthcare

Medical aid group Doctors Without Borders says tens of thousands of people in Cameroon's western regions have been deprived of lifesaving healthcare since December, when authorities stopped their services. Cameroon accused the aid group of being too close to anglophone separatists, which the group denies.

Doctors Without Borders says over 1.4 million people in Cameroon’s restive western regions need humanitarian support, with access to healthcare extremely limited.

The coordinator for the group’s operations in Central Africa, Emmanuel Lampaert, said that’s due to insecurity, lockdowns, and the targeting of health facilities.

He said mortality among vulnerable groups, such as women and children, has increased, and the government’s suspension of their support since December has made the situation even worse.

"Humanitarian and health needs have surges due to the armed violence and notably for the population and several hundreds of thousands of them who have to flee their houses, and who have barriers to access health care. Concretely speaking, this means suffering from malaria or diarrhea for children in the bush, women in labor who are unable to reach health facilities, people suffering from acute respiratory infections, women victims of sexual violence and so on," said Lampaert.

Cameroon’s government in 2020 accused Doctors Without Borders of being too close to separatists who are fighting to create an independent English-speaking state in the majority French speaking country.

Lampaert denied the accusation and said their only goal is to save lives.

"Responding to urgent health needs is our mere and only concern. Viruses, bullets, and infections do not care which side of the crisis one is on and neither do the Doctors Without Borders. That is our DNA and that is the DNA of principled humanitarian medical action," he said.

When contacted by a reporter, Cameroon officials would not say when the aid group, known by its French initials MSF, might be allowed to resume work in the western regions.

Cameroon’s health ministry last week reported about 30 percent of hospitals in the regions are no longer functioning due to separatist attacks.

The health ministry said several hundred health care workers have fled the separatist conflict areas in the past month alone.

Philip Ambe is a government health worker who fled flighting in the northwest town of Bafut last Sunday.

Speaking from the town of Dschang, he said MSF’s work was professional and authorities should allow them to resume saving lives.

"The government does not need to stay mute on this issue [over asking MSF to resume work] again. The situation is very pathetic. People can no longer live in the comfort of their bedrooms. People were kidnapped. Some are in the bush. It is moving from bad to worse. The only way out is dialogue so that things should come back to normal."

MSF was one of the few groups offering free emergency care to Cameroon’s northwest and southwest populations since 2018.

MSF says community health workers it supported last year conducted over to 150,000 consultations for communities in both regions.

And a free ambulance service it initiated transported over a thousand women in labor to hospitals.

Violence erupted in Cameroon’s English-speaking regions in 2017 when teachers and lawyers protested alleged discrimination at the hands of the French-speaking majority.

The military reacted with a crackdown and separatist groups took up arms, claiming that they were protecting civilians.

The U.N. says 3,000 people have since been killed and more than 750,000 displaced both internally and to neighboring Nigeria.

Cameroon Widows Accuse Women of Enforcing Harmful Traditional Rituals

Several hundred Cameroonian widows gathered in the capital, Yaounde, to observe International Widows Day by protesting traditional practices that wives are expected to undergo when they lose their husbands.

Cameroon's minister of women's empowerment and the family, Marie Therese Abena Ondoua, says traditional practices that violate the rights of widows are still practiced in parts of the country.

Fifty-eight-year-old Njoukou Yebom is from Noun, a western administrative unit in Cameroon. Yebom says he regrets that he attempted to force his late younger brother's 15-year-old wife marry him.

Yebom says that in 2018, elders in the town of Foumban where Noun is located asked him to marry his 30-year-old late brother's wife. He was told that if he refused to marry the woman, a stranger to their family would inherit his younger brother's property and leave with his only son. Yebom says he threatened to kill her if she refused.

Yebom's sister-in-law reported him to the Ministry of Women's Empowerment. He says he was arrested by the police and held in custody for attempting to steal property and threatening the girl's life.

Other rites include forcing women to sleep with the corpses of their late husbands and to drink water used in bathing the bodies as a sign they did not kill their spouses.

Amy Banda, chair of Target Peace, an NGO that protects rights of widows, says her group wants women to stop enforcing harsh widowhood rites on peers who have lost their husbands.

"An older widow who had shared her very painful experience with us and we were feeling very sorry for her, was inflicting the same pain on her late son's wife," Banda said. "You do not feel better when you inflict pain on another person because you suffered from that pain. It does not make you feel much better."

Francisca Moto, an officer in charge of the promotion and protection of the family at the women's empowerment ministry, says harmful widowhood rites still persist in Cameroon because of illiteracy and the influence of men.

"Those repugnant practices are attached to witchcraft and so people are afraid to part from them, that they may lose their children and that is why action has to continue," Moto said. "The first thing in case of distress is psychosocial assistance. You need to talk with her so that she can regain her strength to face life. And then one of the most important things that the ministry does is to empower widows economically because most of them are poor."

The United Nations says it observes June 23 as International Widows Day, to draw attention to the voices and experiences of widows and to galvanize the unique support that they need.

The U.N. says the loss of a partner is devastating and magnified by a long-term struggle for basic needs, human rights and dignity.
