Abstract:
Auxiliary drive for a trailer such as a caravan. Said drive consists of a drive unit with a gearwheel. Through linear movement of the drive unit relative to the chassis, said gearwheel can be brought into engagement with a ring gear fitted either on the brake drum of a wheel of the vehicle or on an auxiliary part such as a covering drum fitted over said brake drum. The ring gear preferably lies in a plane outside the plane bounded by the inside of the wheel.
Abstract:
The invention relates to a system, for monitoring and optimising a performance of at least one human operator, comprising—monitoring means (2) for collecting performance parameters, representative for the status of the performance;—processing means (3) for assessing the operator's performance on the basis of said collected performance parameters and for providing the human operator with guiding instructions for improving said performance; and—communication means (4) for communicating the guiding instructions to the human operator, wherein the performance parameters comprise at least one physiological parameter of the human operator, at least one interactive parameter, representative for any interaction between the human operator and his environment and preferably at least one contextual parameter regarding the human operator's direct environment.
Abstract:
A stretcher is usable as a life raft. The stretcher is provided with an elongate support panel having a U-shaped inflatable tube, which surrounds the support panel on its front and sides. The inflatable tube has a first part, which is attached to the support panel and an adjoining second part, which forms an obtuse angle with the first part. The transition between the first part and second part forms a tilting point for the life raft in order to be able to tilt the life raft in the water between a first position in which the first parts of the inflated tube act as floats and a second position in which the second parts of the inflatable tube act as floats. By stowing away the deaerated inflatable tube in the support panel, the life raft can also be used as a stretcher for rescue operations on ice.
