Abstract: An automatic activation device for a parachute has a pressure input for inputting a pressure value and is provided for operating in selectable working configurations according to which a reference pressure is determined either on the basis of the input pressure value or on the basis of a QNH value. Preferably the device can also operate in another selectable working configuration, where a preset time and a reference fall down speed are used.

Abstract: An automatic activation device for a parachute. The device comprises pressure input means for inputting a pressure value. The device is provided for operating in selectable working configurations according to which a reference pressure is determined either on the basis of the input pressure value or on the basis of a QNH value. Preferably the device can also operate in another selectable working configuration, where a preset time and a reference fall down speed are use.

Abstract: The present invention is to improve the mechanical characteristics of a pyrotechnical parachute line cutting device. By enforcing the mechanical traction on the electrical connection wire by Kevlar reinforcement cords. The flexible electrical wire will be connected straight to the propellant detonator to avoid wire connections and fix the detonator trigger straight on the flexible wire. The reefing line will be cut by the blade but also, to secure the cutting action, be melt in the head of the cutter blade after explosion due to the use of special knife material size and an adapted pyrotechnical charge.

Abstract: The present invention relates to a parachute release device provided to be mounted on a parachute, which parachute is provided to be attached to an object. The device has a data processing system having a release signal output and a memory provided for storing data. The data processing system is provided for generating a release signal for opening a parachute. The device further has altitude determining device connected to said data processing system and provided for determining altitude values; and time determination means provided for determining the free fall duration as from the start of the dive. The memory is provided for storing a plurality of series of theoretical dive data, said theoretical dive data indicating for each distance value a corresponding theoretical time. The data processing system is further provided for selecting a series of theoretical dive data in function of the determined altitude values and the determined free fall duration.

Abstract: An electric coil arrangement comprising a coil spool which includes at each end a flange, a coil casing and an outer connection device which comprises terminal connectors anchored within the flange and a connection socket including outer connection plugs, the connecting socket being mounted in fixed relationship on the outer surface of the coil casing at the flange for anchoring the pins whereas the socket and the outer connection pins are shaped so that the pins engage the socket when positioning the casing so as to form said connecting plugs.
