    The automation and robotization of industrial production processes goes hand in hand with the use of similar technological solutions, such as wearable robots, to support workers. The most technologically advanced example of a wearable robot, i.e. a full-body active exoskeleton, is only one of many possible application of various types of exoskeletons. They can also be used to support workers training, remote control of robots and support the process of physiotherapy and rehabilitation.

    Evaluation of the comprehension level of lean management by production and assembly line workers
    dr hab. inż. DOROTA KLIMECKA-TATAR, prof. PCz

    Shaping the working environment in the production space is a very important aspect both from the point of view of occupational health and safety, as well as efficiency and production processes continuity. Modeling conditions at the workplace relates primarily to compliance with legal provisions and minimizing the impact of various factors on the employee. In the light of modern management techniques, the full package of solutions for improving the work environment includes the concept of lean management supported by tools, methods and concepts, such as the 5S method, kaizen, continuous improvement. This paper presents the results of research aimed at determining the level of the lean management basic principles understanding by employees from manufacturing companies.

    Proposals for signal filtering solutions in electronic sound transmission systems
    dr inż. RAFAŁ MŁYŃSKI, dr inż. EMIL KOZŁOWSKI, dr inż. LESZEK MORZYŃSKI, inż. ADAM SWIDZIŃSKI

    Proper perception of sounds in the work environment, most often auditory danger signals, but also verbal warnings from co-workers, increases the degree of safe stay in the workplace. Hence, it is important that the properties of the sound transmitted to an employee with the use of electronic systems are as best as possible adapted to the possibility of its perception by that employee, taking into account the acoustic conditions in the place of use of such systems. Adjusting the sound properties can be realized by influencing the frequency response of the signal, i.e. its filtering. The aim of the article is to propose solutions that could potentially be used in an electronic system of transmitting sound to an employee, enabling filtering  of the signal in frequency bands. The requirements for the properties of measurement octave-wide band filters were analysed. The implementation of filters with a centre frequency ranging from 125 Hz to 8 kHz with the use of digital filters in the sound processor was carried out. The high degree  of compliance of the characteristics obtained in the implemented solution with the standardized measurement characteristics indicates the suitability of the proposed solution for use in sound transmission systems to an employee.
