A new method and apparatus for providing microwave stimulation to a heating cavity was designed to improve the time required and quality of food preparation, and reduce energy consumption. The new method and apparatus are using semiconductor heating technology to supply energy into a heating cavity based on hardware accelerated algorithm to drive time dependent frequency sweep of microwave radiation within the useful frequency range. Hardware accelerated algorithm measures the food state within the heating cavity based on capability to absorb microwave radiation according to individually frequencies and supplies microwave energy into frequency regions capable of absorption using time warping. Hardware accelerated algorithm consists of the analog part and digital part. The analog part controls the ratio between absorbed and rejected energy in real time to improve the energy efficiency, while the digital part performs time warped frequency control and accelerates energy supply into frequency regions capable of absorption to fasten the food preparation. In comparison to conventional methods of supplying microwave radiation higher energy efficiency, faster food preparation and more spatially equal heat distribution is achieved. Furthermore, the new method provides capability to detect the state of food preparation. The result is important for industry of heating techniques and heating appliances, and was introduced to interested public in scope of the project New generation intelligent home.

COBISS.SI-ID: 22029078A new method and apparatus for broadband microwave stimulation to a heating cavity was designed to improve the time required and quality of food preparation, and reduce energy consumption. The new method and apparatus are using semiconductor heating technology to supply energy into a heating cavity, where simultaneously in real time the broadband frequency response is defined within the available frequency range and consequential broadband frequency distribution of microwave radiation energy. The broadband frequency response of the heating cavity is directly defining the capability of microwave radiation absorption within the available frequency range and is determined in real time based on broadband impulse response. The determined broadband frequency response is used for hardware accelerated computation of the inverted value in real time as a basis for broadband frequency distribution of microwave radiation energy in the next moment. New method and apparatus assure at the moment the most efficient microwave heating of cavity in measures of time, distribution of applied heat and energy required. The result is important for industry of heating techniques and heating appliances, and was introduced to interested public in scope of the project New generation intelligent home based on smart devices and wood

COBISS.SI-ID: 22485014The Program IQDom RRP21 and RRP22 projects were focused on the development of advanced ICT services in ambient assisted living environments and smart homes. The emphasis was on data capture, integration of information from different sources and their inclusion in the natural interaction model. Such solutions can significantly improve the daily communication of the user in an intelligent environment.
D.01 Chairing over/coordinating (international and national) projects
COBISS.SI-ID: 22423574This paper presents a proposed system for acoustic monitoring and classification of bee activity, based on audio modality. Beekeeping is one of the agriculture sectors, where ICT solutions provide great benefit for production and animal welfare. The presented system is a general classifier, which can classify normal and swarm bee activity. The activity classification is carried out in a form of recognition architecture, based on principles applied to speech modality. The acoustic models were trained in a two-stage approach using the open audio data provided by the Open Source Beehives Project. The highest classification accuracy of 80.89% was achieved with the proposed general classification approach.

COBISS.SI-ID: 21510678This paper outlines a novel framework that has been designed to create a repository of “gestures” for embodied conversational agents. By utilizing it, the virtual agents can sculpt conversational expressions incorporating both verbal and non-verbal cues. The 3D representations of gestures are captured in EVA Corpus, and then stored as a repository of motor skills in the form of expressively tunable templates.
