Using maritime helicopters innovatively had been one of Canada’s claims to fame in the international military community – Canada had been the first to show that the Sea Kings could be flown off destroyers and frigates involved in antisubmarine warfare by reeling the helicopters in through the use of a Canadian invention – the Helicopter Hauldown and Rapid Securing Device, better known as the Beartrap.[127]

Some 8,000 types of devices are thought to be on the European market, from simple bandages and spectacles, through life-maintaining implantable devices, and screening devices, to the most sophisticated diagnostic imaging and minimal invasive surgery equipment, all directly benefiting citizens.

Other progressive firms like Indal Technologies of Mississauga, Ontario are also building on their expertise and aggressively pursuing foreign markets, sonars for the royal navy, helicopter haul down systems for the U.S. and Japanese navies.

Whereas it is necessary, essentially for the purpose of the conformity assessment procedures, to group the devices into four product classes; whereas the classification rules are based on the vulnerability of the human body taking account of the potential risks associated with the technical design and manufacture of the devices; whereas the conformity assessment procedures for Class I devices can be carried out, as a general rule, under the sole responsibility of the manufacturers in view of the low level of vulnerability associated with these products; whereas, for Class IIa devices, the intervention of a notified body should be compulsory at the production stage; whereas, for devices falling within Classes IIb and III which constitute ...[+++] a high risk potential, inspection by a notified body is required with regard to the design and manufacture of the devices; whereas Class III is set aside for the most critical devices for which explicit prior authorization with regard to conformity is required for them to be placed on the market;

1.3.4.The pendulum block shall be pulled back so that the height of its centre of gravity above that at the point of impact is given by one of the following two formulae, to be chosen according to the reference mass of the tractors subjected to the tests:H = 25 + 0,20 mt for tractors with a reference mass of less than 2 000 kilograms,H = 125 + 0,15 mt for tractors with a reference mass of more than 2 000 kilograms.The pendulum block must then be released so as to strike the protection structure.1.4.Crushing at the rearThe beam shall be positioned over the rear uppermost structural member(s) and the resultant of the crushing forces shall be located in the tractor's median plane.A force, Fv = 20 mt shall be applied.Where the rear part of the ...[+++]protection structure roof will not sustain the full crushing force, the force shall be applied until the roof is deflected to coincide with the plane joining the upper part of the protection structure with that part of the rear of the tractor capable of supporting the vehicle's mass when overturned.The force shall then be removed, and the tractor or loading force repositioned so that the beam is over that point of the protection structure which would then support the tractor when completely overturned.The force Fv shall then be applied.It shall be applied for a minimum of five seconds following the cessation of any visually detectable deflection.1.5.Crushing at the frontThe beam shall be positioned over the front uppermost structural member(s) and the resultant of the crushing forces shall be located in the tractor's median plane.A force, Fv = 20 mt shall be applied.Where the front part of the protection structure roof will not sustain the full crushing force, the force shall be applied until the roof is deflected to coincide with the plane joining the upper part of the protection structure with that part of the front of the tractor capable of supporting the vehicle's mass when overturned.The force shall then be removed, and the t ...
