A trademark - Friendyno registered within a project

October 29, 2020

Currently there is a global trend towards using environmentally friendly alternative energy sources for autonomous low capacity loads. As a result, there has been an increased interest in devices capable of converting small mechanical energy into electricity. At the same time, new types of hybrid permanent magnet devices of the type vernier have emerged, based on the principle of variable magnetic resistance. Design using this principle allows the setting up of a compact direct-powered power generator for low-speed and low-load applications. 

Friendyno - environmentally friendly small power generator with the rotor linear motion - now is a trademark that belongs to Ventspils University of Applied Sciences.



Its authors offer a similar solution to the use of variable magnetic resistance. The generator consists of a fixed inducer with a permanent magnet and winding, an a moving part with magnetic flow switching elements from silicone steel placed on it. The nature of the structure is that the moving part of the generator can be both a linear cyclically moving strip and a strip created in the form a rotating disc. The movable part is made of non-magnetic material such as glass fibres in which silicone steel switching elements are incorporated.       

                                                     

Using mathematical 3D modeling techniques together with experimental studies, the typical performance of such a generator prototype was tested. As a result, Ventspils University of Applied Sciences researchers in cooperation with Joint Stock Company "LATVO" have developed an original technical solution which has improved and simplified the production process of such generators.                               

The novelty of the proposed technology is an inducer design that uses a UNICORE strip [1] technology that allows it to switch to environmentally friendly magnetic core production without waste.                           

The use of the new technology creates new opportunities to create stator teeth for knots that cause linear and rotating movements of magnetic flux. In this case, the magnetic flow generated by permanent magnets is perpendicular to the flow in the inducer magnetic circuit. The use of this technology together with the new design of the generator makes it possible to significantly reduce material and operating costs in the manufacture of the device.                                     

                                                                                                                 

The intellectual property and novelty of the solutions developed are recognised in ten patents. Generators with a capacity of 1-10 W are designed to operate portable electronic devices or to charge their batteries. Potential users are bicycle owners who need to charge portable electronic devices. This may also create hand-operated generators for outdoor use.                                               

                                                                                                               

The proposed solution aims to create a competitive energy source that would meet the growing demand for cyclists' smart electronic devices.

By Rota Rulle • February 5, 2026
On January 16 within the framework of the State Research Programme of Ventspils University of Applied Sciences, Professor Una Libkovska, within the framework of the State Research Programme project "Development of evidence-based solutions for the effective improvement of professional competence of adults and assessment of the transfer of its results to practice in Latvia" (VPP-IZM-Education-2023/4-0001), participated in a meeting with entrepreneurs organized by the State Education Development Agency and the Ventspils State City Education Board on opportunities and challenges for adult learning. During the meeting, the opportunities offered by the skills management platform STARS for adult continuing education and professional upskilling were discussed, with a particular focus on the European Union projects "Training for Workers" and "Digital Skills for Experts". The discussions emphasize the importance of employers in providing support to employees in the process of starting training, as well as the need to establish purposeful cooperation between entrepreneurs, local government and educational institutions. VIAA's Department of Adult Education presented the learning opportunities offered by the STARS platform, as well as the necessary support for employed adults to start their studies and the role of the municipality in providing this support. In the second part of the event, meetings were held with municipal specialists and adult education organizers, representatives of youth and cultural work and other interested parties. The discussion discussed ways to strengthen cooperation in adult education, as well as identifying the necessary support from VIAA in reaching out to adults and motivating them to engage in learning. The event brought together more than 20 representatives of business and institutions of Ventspils municipality, who actively participated in discussions, shared their experience and expressed proposals for improving the adult education offer. The meeting reaffirmed that coordinated and targeted cooperation between state institutions, local governments, educational institutions and employers is an essential prerequisite for the effective development of adult skills, strengthening competitiveness and sustainable employment.

Defense of Sanita Lasmane’s Doctoral Thesis: “Analysis and Improvement of Labor Market Assessment Approaches: A Case Study of Latvia”

By Rota Rulle • February 3, 2026
Ventspils University of Applied Sciences invites you to the public defense of Sanita Lasmane’s doctoral thesis, “Analysis and Improvement of Labor Market Assessment Approaches: A Case Study of Latvia,” for the acquisition of a Doctor of Science degree (Ph.D.) in Social Sciences. Scientific Supervisor: Professor Sergejs Hiļķevičs, Dr. phys. The author, S. Lasmane, will present innovative research aimed at adapting labor market assessment approaches specifically to the socio-economic situation in Latvia. The thesis was developed within the joint doctoral study program “Economics and Business” offered by three higher education institutions: Ventspils University of Applied Sciences, Vidzeme University of Applied Sciences, and the RTU Rēzekne Academy. Research Relevance: S. Lasmane’s research offers solutions in two directions of national importance: - A New Human Capital Assessment Approach: A new approach has been developed for the quantitative assessment of human capital at national and regional levels using regularly available data. - Estimation of Cobb-Douglas Production Function Parameters for Latvia: The Cobb-Douglas production function has been adapted to Latvian parameters, assuming that the sum of the coefficients α and β is not equal to 1. This was achieved by using traditional resources—capital and labor—as well as replacing them with potential "invisible agents" in the economy: banks and enterprises. Scientific Reviewers Associate 1.Professor Aija van der Steina, Dr. oec., Vidzeme University of Applied Sciences, Latvia; 2.Professor Sandra Jēkabsone, Dr. oec., University of Latvia, Latvia; 3.Associate Professor Ramutė Narkūnienė, Ph.D., Utena University of Applied Sciences, Lithuania.

New Window into the birth of massive stars: The IVARS Project Demonstrates High-Cadence Radio Monitoring of Massive Protostars

By Rota Rulle • January 26, 2026
An international team of astronomers has successfully completed the IVARS (Interferometer for Variable Astrophysical Radio Sources) project, delivering a new observational capability for studying the formation of massive stars through time-variable radio emission. By combining two radio telescopes at the Irbene Radio Observatory in Latvia into a dedicated single-baseline interferometer, the project has enabled the first sustained, high-cadence monitoring of radio continuum variability in high-mass protostars, carried out simultaneously with maser monitoring.
