CNets has sponsored a master thesis analyzing a new method to create a health indicator for machines. The master thesis was handed in and evaluated by KTHs School of Electrical Engineering and Computer Sciences (EECS).
The work is based on distance measurements transformed into a vector space through a feed-forward neural network. The neural network is trained using a multi-objective optimization algorithm to optimize criteria that are desired in a health indicator. The constructed health indicator is used as input to a gated recurrent unit (a neural network that handles sequential data) to predict the remaining life of a system in question.
The Master thesis Machinery Health Indicator Construction using Multi-objective Genetic Algorithm Optimization of a Feed-forward Neural Network based on Distance was carried out by Jacob Nyman in the field of machine learning:
CNets has sponsored a bachelor thesis targeting the integration of the Keto-Mojo glucose meter into the LinkWatch eHealth platform. The thesis was handed in and evaluated at KTHs School of Engineering Sciences in Chemistry, Biotechnology and Health (CBH).
As different medical products send data to their own platforms, it becomes challenging for both patient and care provider to take and keep track of all available vital parameters. This lack of a universal platform connecting to devices of different manufacturers, combining all available data has been the initial motivation to develop LinkWatch. It provides a platform where all the patient’s medical measurements can be collected and visualized. The mobile application, developed both for iOS and Android have been programmed in Kotlin and Swift to provide a secure and efficient data transfer between the blood glucose meter and LinkWatch’s web server. The mobile application can connect to the blood glucose meter with Bluetooth and transfer its measurements to the LinkWatch’s web server. When the records are stored in the LinkWatch system, the patient can see their glucose levels along with other vital parameters.

The work was submitted to the KTH, School of Engineering Sciences in Chemistry, Biotechnology and Health (CBH), Biomedical Engineering and Health Systems in 2021 in Swedish:
Air pollution induced respiratory diseases are rapidly increasing in large cities. Treatment of diseases caused by air pollution is estimated to cost approximately 2% of GDP in developed countries and 5% in developing countries. AsthmaWatch, developed in the GOEASY project incorporates a Galileo based secure mobile air quality monitoring platform into a mobile smartphone app that enables users to identify places and pollutants that they can avoid. Every day outdoor air quality changes on a street-by-street basis. By crowdsourcing air quality information from mobile sensors, the app helps citizens proactively avoid unhealthy environments.
Pollution varies in location and distribution strongly related to the weather and people suffering from Asthma or from pollen allergies can use detailed forecast data to avoid highly polluted areas to avoid negative impacts on their health. AsthmaWatch visualizes measured pollution for the Stockholm area providing detailed forecasts and rout recommendations based on pollution data:

Övervakning av broar i dag och i framtiden; Tony Janhunen, Department Manager, Ramboll.
CNet has developed a Sensor field kit to monitor air pollutants within urban areas. The field kits can measure different pollutants and transmit their location where the measurement is taken to visualize the current level of different pollutants within the area. The data is stored and the GoEasy App can visualize historical readings at different points-of-interest. The new generation of field kits can measure small and larger particles as well as NO2 and are can be used walking, cycling or motorized modes of transportation. The field kits run on an external batteries which enables measuring and transmitting data for several days. The new generation of field kits will be deployed in a Pilot in Stockholm collecting data to generate a pollution map of the city.
African countries face the need to meet a fast-growing energy demand but its nations can pick from a portfolio rich in renewable energy sources, including water, sun and wind, among others. Building on experience gathered around the globe Africa can design it’s energy sector for the future.
Half of the continent has solar radiation intensities of more than 7000 kWh/m2/day, the perfect premise for utilizing solar power. Renewable energy sources offer additionally more independence from fossil material, improved resilience and sustainability.
CheckWatt, one of CNets subsidiaries, offers configurable energy related solutions for different needs. In the last year CheckWatt has extended their business to Europe. The companies expertise and experience is leading in the Swedish market and internationally competitive. CheckWatt is proud to announce that they have entered their first contract in Kenya, which entails the deployment of a new solar energy installation in Kenya. Dan-Eric Archer, VD of the company, supervised delivery and installation of solar meters, real-time measuring at the connection point to the electrical grid, Plug and play production demo on screen himself:
CNets spin-off company CheckWatt is expanding services with solutions to store energy and manage usage intelligently.
The fast growing market of private solar installations and electrical vehicles are followed by extended needs regarding the electrical infrastructure but also offer new possibilities for utilization. In 2019, the market for electric grid ancillary services was approximately 1.5 billion SEK. Svenska Kraftnät forecasts that it will double twice by 2023, driven by the growing share of intermittent power production (solar and wind) within the electricity mix and an increased integration within Europe (regulating power as an export product). Meanwhile the fees for the electrical network infrastructure grow significantly without smarter network solutions, so smart solutions that avoid unnecessarily future costs are needed, a conclusion that the European trade association has come to: “Smart storage and control before cable!”
With already more than 200.000 electrical vehicles registered in Sweden, each about 10 kW on average, these have already the same peak power as 2 nuclear power plants. Electric cars are fundamentally changing the energy system, and they are rather an asset than a burden. The advantage of electric cars is that they do not have to be fully charged all the time. The effect can be adapted to the needs of the electricity network, cushioning peaks through utilizing off times.
EMS (Energy Management System) is a service for energy-related data and smart control for hybrid inverters (photovoltaic systems with connected battery storage for example) and electric car chargers that can minimize power-related costs locally in the building and perform frequency regulation for Svenska Kraftnät, which generates revenue for the owner.
CNets spin-off company CheckWatt is expanding its product portfolio to meet the growing popularity and needs of electrical vehicles (EVs). Sweden is ranking among the world’s top ten market for best-selling plug-ins since 2015.
In December 2020 a total of 217,704 plug-in vehicles have been registered, 148,889 plug-in hybrids, 62,870 all electric cars and 5,945 all electric vans have been registered in Sweden since 2011. As EVs are actively supported by the government with financial grants and charging at home is cheaper than petrol, diesel or public charging more home owners are looking for smart solutions. CheckWatt does not only want to offer homeowners a solution to charge their cars, but also to manage their electrical home installations, solar installations and to maximize savings reducing power-related costs. Solutions enable users to visualize charging together with other energy-related data. For starters CheckWatt initiated a collaboration with EpSpot and Zaptec, further collaborations are being negotiated.
The IoTBridge team, a subsidiary of CNet, is now monitoring Västerbron, one of Stockholms main bridges. Inaugurated 1935 the bridge has an overall length of 600m, of which 340m stretch over water. About 50.000 vehicles pass this bridge per day, making it an integral part of Stockholms infrastructure.
The team has installed sensors for monitoring the health status of Västerbron. Acceleromters and strain gauges will continuously measure vibrations, stress and strains on the bridge. Raw data is sent to IoTBridge Cloud where it is transformed and synchronized with a digital twin of the bridge. Machine learning and advanced mathematical algorithms are applied to assess the structural health of the bridge. The ongoing monitoring and the analytical results are visualized in an easy-to-use app.
The European project SDK4ED finished a full success. A great team of 11 partners, including CNet, in 7 countries worked hard together for three years. A cooperation that created a software development toolkit for energy optimization and technical dept elimination. Work that resulted in 59 publications, to say the least.
