Mobilephone advisor system

The system supports the sale process of mobile phones by providing easy to use user interfaces to the customers and detailed informations about the available phones and related subscriptions. The main components are a mini PC, a touchscreen, a web camera and a special lifting sensor device to which the phones are attached. The user interface is implemented by a web client, with which the customers can filter the phones by detailed options and select the most appropriate product. The lifting sensor detects which phone is lifted and the client displays the details of the phone. Using the attached camera the system determines the gender and age of the customers and based on these informations plays the demo video that is suitable to the customer.

The system is currently used in the stores of Media-Saturn-Holding Ltd. in several countries, including:

• Austria
• Azerbaijan
• Germany
• Hungary
• Italy
• Netherlands
• Poland
• Russia
• Spain

White good product advisor system

Provides up to date information about the electrical household products available in the stores to the customers. Consists of a web client that supports wide renge of browsers, several data updater modules and a central data source. The web client includes an advisor module, which asks questions from the customers and filters the products based on the provided answers. The selected products can be compared based on their specifications and energy costs, and the customers can send the result in e-mail to themselves or can print it.
The system was introduced in the stores of Media-Saturn-Holding at the end of summer 2014.

Network management

The system has several independent modules which communicate with each other through the network and database. This structure provides expandability, scalability and fault tolerance. The system is implements the supervision and control of the complete infrastructure.
It treats the elements of the infrastructure as objects, from which any hierarchy can be formed, e.g.: sites, subsites, equipments. Specified attributes can be given to the equipments and these store the data of the equipments. The system processes the events related to infrastructure, and turns them into data, which can be retrieved later. It generates alarms which are based on editable rules of the equipments and their attributes.
The desktop client provides the user interface. It displays the components in tree hierarchies and also in map-form for the users. It provides surfaces to view, modify and query the elements of infrastructure related data. It indicates the network alarms in different ways depending on their level. It is possible to issue commands to the equipments in automated way as well.

Building management

The distributed building management system performs point-based measurement of different attributes (e.g.: energy consumption, temperature), records data and control tasks for flats, houses and industrial buildings. It consists of meter devices placed at specific locations, several processing units and a web client. The web interface displays real time and historical data in tabular and graphical ways and it also records user interventions for auditing purposes. The individual processing units can send the data to each other through the network and database, so the load can be distributed optimally between them which makes the system scalable.
