The paper presents an analysis and assessment of recorded accelerations acting on Hybrid III dummy during emergency braking of a passenger lift. The dummy was equipped with a system of three-axis accelerometers. The type of progressive safety gear that has the shortest time of reaction and the shortest effective braking distance in its group, was chosen for tests. The tests were carried out on an emplacement, which simulated the movement of passenger lift. Tests of emergency braking were performed at variable load of a cabin corresponding to the mass of different passengers number. The cabin was dispelled by the gravity force using its free-fall. During the braking, the values of accelerations effected on individual parts of dummy, were measured. Based on them and using HIC and Nij indexes, the impact of temporary accelerations on passenger's health was determined.

This paper presents a calculation algorithm for a thermoelectric generator fitted in the exhaust system of a combustion engine. The viability of the presented calculation method was verified on an actual combustion engine. The calculations were performed for a BMW engine, and the generator design was based on a prototype from the same manufacturer. The paper includes calculations of the thermal cycle and of the parameters of exhaust gases from the engine. Subsequent calculations cover heat transfer from exhaust gases to the thermoelectric module and the amount of electric energy obtained from a series of modules. In the last part, the focus is on the influence of engine speed on the performance of the thermoelectric generator.
