Abstract: A safety device is provided. The safety device (100) is for securing an individual to a concrete element (2) of a structure during construction work. The concrete element (2) is of the type comprising a concrete body (4) having one or more lifting pins (6) embedded in respective lifting pin holes (8) in said body.

Abstract: A tracking device is configured to estimate a track for at least one possible target and is configured to receive incoming measurements and to process measurements and tracks. The tracking device includes a storage and a computational device. The tracking device is also configured to divide all measurements into a set of considered measurements and a set of unconsidered measurements for each passive track.

Abstract: A lifting system for lifting a separate pallet with a heavy load is disclosed, the lifting system including two or more carrier elements and a suspension device in the form of a chain sling or a strap sling with double as many fastening ends as the number of carrier elements, wherein each of the carrier elements includes a stiff supporting beam and a distance element and is arranged so that two of the fastening ends of the suspension device can be fastened to the supporting beam in opposite ends thereof, and wherein the distance element is dimensioned and mounted onto the supporting beam in such a way that it prevents displacement of the carrier element relative to a pallet in the longitudinal direction thereof, when the carrier element is mounted transversely through the pallet. Furthermore, a carrier element for such a lifting system is disclosed.

Abstract: A tracking device estimates a track for at least one possible target and is configured to receive incoming measurements and process measurements and tracks. The device has a storage device and a computational device and an association module to calculate an association between a measurement and a track. The device further has an output module to output a sequence of track updates from an assignment module maintaining a set of active tracks using the association module as a function of active tracks and the incoming measurements to calculate associations, containing possible track updates and deciding which track updates to keep in the active tracks set and which to add to a passive tracks set. Computations on the passive tracks may be deferred until at least one passive track handling criterion is fulfilled. The computational device may activate and transfer a passive track from the passive set to the active set.

Abstract: A lifting system (1) for lifting a pallet (5) with a heavy load (6) is disclosed, said lifting system comprising two or more carrier elements (4) and a suspension device in the form of a chain sling (2) or a strap sling with double as many fastening ends as the number of carrier elements, wherein each of the carrier elements comprises a stiff supporting beam (7) and a distance element and is arranged so that two of the fastening ends of the suspension device can be fastened to the supporting beam in opposite ends thereof, and wherein the distance element is dimensioned and mounted onto the supporting beam in such a way that it prevents displacement of the carrier element relative to a pallet in the longitudinal direction thereof, when the carrier element is mounted transversely through the pallet.
