An apparatus for an exercise task includes a pneumatic arrangement, which includes a pressure source, a pneumatic controller, pneumatic transfer channels, and at least one pneumatic resistor element, which includes a pneumatic cylinder with its piston. The apparatus additionally includes a mechanical lever arm structure or another mechanical connecting structure, which is for a user's limb contact and which is at a second end connected to the pneumatic resistor element. The apparatus additionally includes a sensor structure, a calculation arrangement and a display. The sensor structure is arranged to measure at least one measurement quantity of the exercise task and, based on the measurement, the calculation arrangement is arranged to form information on the display of the apparatus, regarding the power and/or force and/or range of motion of the exercise task. In the invention, regardless of the number of pneumatic resistor elements, the sensor structure includes one pressure sensor only, and to compensate for the small number of sensors, the calculation arrangement includes a correlation-taught calculation unit, which comprises a correlation algorithm taught with a larger number of sensors than the number of sensors in the apparatus, concerning the correlation between power and/or force and/or range of motion of the exercise task and the measured information.

Exercise apparatus

A collector element for collecting solar energy. The collector element is made of metal and comprises at least one elongated central ridge comprising at least one internal flow channel for a heat transfer medium, first and second elongated side ridges at opposite sides of the at least one central ridge and an elongated depression between each two adjacent ridges. At least one side ridge comprises at least one fastening element by means of which at least one substantially solar radiation permeable covering element is to be fastened to the collector element for covering at least the at least one elongated central ridge of the collector element.

Collector element for collecting solar energy

The invention relates to a solar collector () comprising a collector element plane comprising a set of parallel metallic collector elements () for collecting solar energy. The collector element plane, on its side to be arranged to face the sun, comprises a set of parallel, elongated ridges (R, r) formed by the metallic collector elements (), and elongated depressions (v) between the ridges (R, r), and that at least some of the ridges (R, r) comprise therein a channel () for a heat transfer medium. The invention also relates to a collector element. The invention further relates to a building roof, a building, and a solar energy recovery system comprising said solar collector ().
