Where Greece had one of the least Covid cases per million citizens at the beginning of july, the number of cases is rocketing since the end of July/beginning of August. From the 5,623 cases, “1,438 are considered to be related to travel from abroad and 2,705 are related to an already known case. Greece recorded 203 new cases of COVID-19 in 24 hours, the single largest daily number of cases since the pandemic began.” (Greek City Times, 10th August).

Covid cases Greece

Initially, Greece had a large success fighting the coronavirus by an early lockdown in March. Since half June, some lockdown measures have been lifted. The daily cases have steeply increased. ““We must say that the increase in cases is mainly due to the relaxation of compliance to the measures within our country in July. And I believe we all have a responsibility for it. Only 10% of cases are imported, most cases at the moment are domestic,” he (Prime Minister Kyriakos Mitsotakis) continued.” (Greek City Times) “Authorities sealed a popular beach bar on Mykonos island after seven employees tested positive for the virus, Skai tv reported, while officials on Ikaria island intervened in a village celebration with dozens of people.” (Anadoulu Agency). Further, the Covid probably spread from travel to and from Balkan countries, which have a high number of cases.

Travel, tests and measures

Out of the 124 cases Saturday, 29 cases where noticed at one of the country’s entrance gates. Because Covid cases were low at the time, Greece began to consider how Greece could be re-opened in May. That meant lifting the non-travel and quarantine regulations. Instead, persons entering Greece are tested on Covid.

Since August 1, the Police have fined 2,042 persons for violating the Covid regulations, 57 shops were shut. “Parties at Chersonissos: ‘We’ve been drinking and cramming on each other every night’” headlines the AD, a newspaper in the Netherlands.

Some measures have already been taken: on Thursday, restrictive measures were imposed on the island of Poros in the Saronic Gulf. At Amplelonas (in Central Greece) measures were taken following the infections on a wedding. These measures included the suspension of events, religious processions and open markets. (Neokosmos)

Last Friday, Nikos Hardalias (Deputy Minister for Civil Protection & Crisis Management) announced the following measures:

  • As of August 12, visitors coming from Malta are required to show proof of a Covid-19 negative molecular test (PCR) taken up to 72 hours prior to arriving in Greece.
  • Following a relevant recommendation of the Holy Synod of the Church of Greece, all processions are suspended indefinitely, as are all rural trade fairs.
  • The measure of banning standing customers in all nightclubs, bars, restaurants and live music venues, currently in effect, is extended until August 31

Earlier that week, Prime Minister Kyriakos Mitsotakis stressed the importance of the ‘national vaccine’: “which is nothing more than our ‘philotimo’ and together we must follow the measures indicated by the experts and I am sure that if we do we will emerge victorious from this difficult battle as well.”

ASN Smart algorithms and technology offer the IoT approach and results you need.

Since 2006, ASN has successfully helped many international organisations. With data analysis, algorithms, security and successful implementations for their embedded IoT applications.

  • 62 Tried & tested IP blocks that are used worldwide
  • Combability with Arm Cortex-M technology, used in over 80% of IoT devices
  • Biomedical ECG, EMG, Lab-on-chip and vital life signs algorithmic solutions
  • High precision gas and flow rate measurement solutions
  • Human/object radar based motion tracking
  • Sensor signal processing

62 application IP Blocks

Our tried and tested application IP blocks are tried and tested worldwide for variety of IIoT/IoT applications, including:

  • Biomedical (EMG, ECG, vital life signs, lab-on-chip)
  • Smart Grids
  • Machine and motor maintenance
  • Oil and gas
  • ADAS (automotive driver assistance)
  • Smart street lighting
  • Noise cancellation
  • Industrial sensors

Compatibility with Arm Cortex-M technology

The ASN Filter Designer has an automatic code generator for Arm Cortex-M cores. This means that we support virtually every Arm based demo-board: ST, Cypress, NXP, Analog Devices, TI, Microchip/Atmel. And over 200+ other manufacturers. Our compatibility with Arm’s industry standard CMSIS-DSP software framework removes the frustration of implementing complicated digital filters in your IoT application. As a result, you get code that is optimal for Cortex-M devices and that works 100% of the time.

From algorithmic concept to NPD

Our NPD (product development process) provides a systematic and efficient way of productising a developed IoT algorithmic concept. This allows you to get your IoT application to market based on first time right principles.

Biomedical ECG, EMG, Lab-on-chip and vital life signs

One of our specialised sectors is the one of biomedical. For this sector, our ASN Filter Designer is very suitable for data filtering of ECG and EMG. After data filtering, you can export your cleaned data to Matlab. Or immediately export it to an Arm microcontroller for deployment. In parallel to the ASN Filter Designer, we have developed algorithms for a Lab-on-chip and Vital Life Signs measurement.

High precision gas and flow rate measurement solutions

One of our other specalisms are high precision gas and flow rate measurement solutions. Our comprehensive collection of application IP blocks has allowed many international companies to obtain outstanding measurement performance for their IoT applications!

And we can do much more for you… just ask us!
