Wireless transfer technology has become an effective and reliable option to replace the conventional wire transfer technology. The topology involves a power transmitter connected to the grid, and a power receiver attached to the battery. A wireless power transfer system should satisfy three conditions, namely high efficiency, large air gaps and high power. Recent studies have provided wireless mid-range charging technology to transfer power through resonant inductive coupling.

The theory of resonant inductive coupling has therefore been used as the main technology in the design and implementation of a wireless charging system that was successfully implemented on an Automated Guided Vehicle (AGV). The intention was to wirelessly transform and transfer an alternating oscillating waveform into a DC voltage, to demonstrate instantaneous power transfer.

Radio and newspaper advertisements are used by small and medium enterprises (SMEs) to create awareness about the existence of businesses, their products and services, as well as to communicate with potential consumers. The present study, localised in the city of Welkom, Free State province, focuses on the effectiveness of radio and newspaper advertisements as promotional tools to enhance the profitability of SMEs. The main objective of the study was to investigate the influence of radio and newspaper advertising on consumer buying decisions. It also investigated in particular the effect of radio and newspaper advertisements on the decision making of consumers regarding products or services. The relationships between consumer age and gender and decision making were also examined. Study findings revealed that radio advertisements do not appear to influence the buying decisions of consumers as most consumers are passive listeners and do not concentrate on such advertisements. Contrastingly, there is wide agreement that newspaper advertisements do influence buying decisions. One implication from the study is that SMEs might increasingly consider using newspaper advertising for more effective consumer communication.
