Abstract: This invention relates to an indoor lighting and climate system, comprising a plurality of lighting units (1) arranged in a dispersed manner in a room (2) and a control unit (3) arranged to control the operation of the lighting units (1) in relation to pre-set climate settings and input signals from at least one temperature sensor (4), wherein each of said 5 lighting units (1) include a cup shaped housing (100) with an opening (101), a lamp attachment (102) for a lamp (103), an open inside space (105) between said lamp (103) and said cup shaped housing (100), and a fan (104) arranged to produce a forced air flow (2) in said space (105), characterized in that a circumferentially extending inner dividing wall member (107) is arranged within said cup shaped housing (100), which 10 circumferentially extending dividing wall (107) separates said open inside space (105) from a heat flow channel (106) arranged within said cup shaped housing (100).

Abstract: This invention relates to a valve arrangement (8, 18) arrangeable to be used in a rebreathing system (1), said rebreathing system (1) comprising an oxygen supplying member (5, 15), a breathing mask (4, 14), a gas reconditioning unit (3, 13) where carbon dioxide in the exhaled gas is absorbed, a counter lung (2, 12) and a breathing passage (42, 142), wherein said valve arrangement (8, 18) is arrangeable to be used in a back and forth (two way?) breathing passage (42, 142) between said counter lung (2, 12) and said breathing mask (4, 14) of said rebreathing system (1), said valve arrangement (8, 18) containing an oxygen supply arrangement arranged to supply oxygen to the breathing passage (42, 142) provided that a predetermined level of oxygen pressure is exerted on said supply arrangement from said oxygen supplying member (5) and arranged to close the breathing passage when said oxygen supply pressure is below a predetermined level.

Abstract: The present invention relates to a safety method in connection with SCUBA diving to control a diver's buoyancy, in which method the diver (11) is equipped with diving equipment comprising at least one air pressure tank (1), a valve device (2) connected to the pressure tank (1) and arranged to supply air from said pressure tank via first supply means (5) to a breathing regulator (4) and via second supply means (7, 9, 12) to an inflatable diving jacket (6) in order to control the diver's buoyancy, an actuator (8) being able to automatically initiate inflation of the diving jacket (6) when the diver has not affected the air flow through the breathing regulator (4) for a certain time period, said actuator (8) being controlled by an actuation mechanism (20) that automatically sets the actuator in active mode when the diver is within an actuation zone (A), wherein in order additionally to improve the diver's buoyancy the actuator (8) is also arranged to automatically initiate dumping of a weight (11) carried by the
