In recent years, research in the field of controlled chaos is very active and new ideas about the possible application of chaos in cryptosystems have arisen. The proof of innovative concept performed through the following activities determined to which extent this kind of encryption satisfies the market needs:

1. Market potential study
2. Analysis of the properties of different chaotic systems
3. Purchase and installation of laboratory equipment
4. Development and testing of various prototypes
5. Evaluation of the results with respect to the specified requirements
6. Developing a commercialization plan

The project has resulted in an encryption device based on chaos theory. The device is realized in the form of software and hardware encryption systems in order to exploit advantages inherent to chaos. In the software encryption system the chaotic signal is generated using a computer algorithm, while in the hardware encryption system the chaotic system is generated using electronic/electric circuits. Built systems have been analyzed in detail and evaluated with regard to market requirements. Furthermore, directions for future development and commercialization have been defined, e.g. upgrade of the system for the implementation in the existing TCP/IP network, contacting firms with a view to cooperating in commercialization, etc.

3. Capacitive Passive Identification System – CapsID
Project ID: PoC5_12_1
Lead beneficiary: Faculty of Electrical Engineering Osijek
Project leader: Dr. Davor Vinko, Assistant Professor
Total project budget: 351,195.20 kn
Approved budget: 294,161.37 kn
Project duration: 1st January 2014 – 31st December 2014
Recognised centre: Business Incubator BIOS, Osijek

The capacitive passive identification system (capsID) is an electronic system for monitoring and security identification of products, movable and immovable objects and living beings. The proposed system is based on the concept used by the existing identification systems and it consists of two separate devices: a tag and a tag reader. The tag can be active or passive. Active tags have their own power supply (usually a battery), while passive tags have no on-board power supply, but instead are wirelessly powered by the reader device.

A key technical feature of the proposed system is capacitive wireless energy transfer from the reader device to the passive tag. Capacitive powering enables integration of the passive tag within an object, inside of a product, and implantation in living beings. In addition, the major advantage of capacitive powering is the ability to operate within an electrically conductive object. Such feature is not available in inductively powered ID systems which are dominant nowadays.

The expected final project result is a functional system prototype which consists of an active reader and a passive tag which uses capacitive energy transfer from the reader to the passive tag, and enables data transmission from the passive tag to the reader, with an emphasis on the ability to work inside an electrically conductive object.


4. Multifunctional Wireless Access Control System – mWAC
Project ID: PoC5_12_2
Lead beneficiary: Faculty of Electrical Engineering Osijek
Project leader: Dr. Drago Žagar, Full Professor
Total project budget: 201,611.37 kn
Approved budget: 113,934.76 kn
Project duration:  1st January 2014 – 31st December 2014
Recognised centre: Business Incubator BIOS, Osijek

An Electronic Access Control System is a selective restriction of access to a place or other resources and has been used for a long time. The concept itself is composed of an access control mechanism to allow or deny access to places and resources with electronic identity authentication. The electronic identity is mainly enforced by using magnetic and radio cards or specialized devices. Tracking objects and people through the spatio-temporal domain as well as one card per object provides personalized identity allowing simplicity of use.

The proposed project encompasses Wireless Sensor Network (WSN) implementation in conjunction with embedded computer systems. The goal is to implement a hybrid solution that would be fault tolerant, price competitive, data distributed and free of large infrastructure, complex setup and usage. Low priced access points (a wireless reader and an electromagnetic lock) will provide a more effective solution than the existing systems. The aim of the project is to prove technical implementation of a large number of access points in ACS using WSN which is not suited for real-time communication. Furthermore, a reliability validation of the system speed of communication is an important factor that will be tested throughout the project.

Main project activities include: simulation of the proposed system solution and implementation of the functional prototype installed and used at the Faculty of Electrical Engineering in Osijek financed by PoC (30 access points). Testing the system reliability from access points to coordinator devices will be conducted using WSN which will lead to enhanced modeling of real-time communication. The main administration Web application will be developed as a standard cloud-based solution using shared services and infrastructure. The desired goals will be reached by PoC financial support for communication systems, using resources of the Faculty of Electrical Engineering, project associates and a newly employed engineer. The final project result is an enhanced system model by means of which efficiency and commercialization solutions will be determined.


5. Chaotic PLC Modem
Project ID: PoC5_12_14
Lead beneficiary: Faculty of Electrical Engineering Osijek
Project leader: Dr. Marijan Herceg, Assistant Professor
Total project budget: 399,288.59 kn
Approved budget: 264,138.27 kn
Project duration:  1st January 2014 – 31st December 2014
Recognised centre: Business Incubator BIOS, Osijek 

In this proof of innovative concept a new chaos-based communication system for data transmission using power line (Power Line Communication - PLC) is proposed.  Advantages of chaos-based transmission of information are, first of all, a simple hardware implementation (simple way of chaos signal generation, demodulation in time domain, non-coherent receiver), robustness  to  multipath propagation, a very wide frequency spectrum with low amplitudes that allows coexistence with other communication systems, high level of data security due to the aperiodic nature of chaotic signals.

The project aims to demonstrate the technical feasibility and to construct a chaotic PLC modem prototype for digital signals based on:

- one of the existing modulations („On-off“ modulation, modulation using discrete change of a chaotic signal, etc.); 

- a completely new modulation method, in respect of which the team members have been recommended by the registered European patent agent to protect their intellectual property rights.

Therefore, in parallel with the process of demonstration of the technical feasibility, the process for the protection of intellectual property rights would be initiated.

The realization concept and expected results:

In the first phase, the focus would be on the demonstration of technical feasibility of the proposed solution and on activities related to the protection of intellectual property rights. If the technical feasibility were confirmed, the second phase of the project would start, which would consist of creating a chaotic PLC modem functional prototype based on one of the existing modulations. In the third phase, the prototype would be tested in laboratory conditions and compared with PLC modems based on the existing standards. After evaluating the results, the commercialization plan would determine both the market potential and direction for the commercialization of the proposed solution.    

The expected project results include the intellectual property rights protection for the new modulation, demonstration of the chaotic PLC modem technical feasibility, which includes the transmission of a digital signal over PLC with a chaotic signal carrier and the construction of a chaotic PLC modem functional prototype based on some of the existing modulations as well as on a completely new modulation method.

PowerSurface is wireless charging technology for mobile devices (smartphones and tablets).  Technology enables wireless charging on a surface which is significantly larger than the surface of the mobile device. Mobile device can be wirelessly charged on arbitrary section of active surface. Two or more devices can be charged simultaneously. The project includes development of a functional prototype that will demonstrate the technical feasibility and potential for implementation of the proposed technology.

The goal of project proposal is to prove a concept, i.e. proposed PowerSurface technology, by developing and making a functional prototype of a wireless charging system. Project activities cover analysis of wireless energy transfer, optimization and laboratory testing, followed by prototype development. At the same time, the electromagnetic compatibility and impact on human health will be continuously evaluated in concordance with legislation of the Republic of Croatia. Results of the evaluation during each project activity will be used to define guidelines leading to the development of a functional prototype.

Proof of concept is needed to demonstrate technical feasibility of functional prototype which satisfies the conditions prescribed by the legislation of the Republic of Croatia, the necessary technical specifications and customer requirements which will be defined through a market research study.

Expected results of the project proposal are prototype of wireless charging system for mobile devices which uses PowerSurface technology and conducted analysis, i.e. measurement of electromagnetic compatibility and impact on human health. System prototype will be implemented in home and business inventory.
