Cushion Module

A special module design that is a hybrid between a plate and a spiral-wound module has been developed by the research institute GKSS in Germany. Here, two membrane sheets are welded together (by heat or ultrasonic welding) to a sandwich structure with a permeate spacer between the two membranes. A multitude of these sandwiches, each with a central hole, is arranged on a central perforated tube that removes the permeate. Each membrane sandwich is sealed from the feed to the permeate side at the central perforated permeate

The automotive industry favours sets of parts assembled by the plastic furnisher and including non-plastic elements such as metal components, electronics. .. This simplifies purchasing and on-line operations. For example, a seat module includes the frame, cushioning, slide system, position control device. .. 

SIT ISIT. Pin cushion distortion (see above) results in a variation of the modulation transfer function across the target of the detector with a maximum distortion present in the periphery. 

Many new robotic designs are being created. Vehicles looking like the lunar excursion module are common in bomb disposal units. Robotic backhoes and other devices are now in use. However, the concept of robotics can be as simple as placing an explosive ordnance item on a 3-in. foam rubber cushion atop a child s plastic basin-shaped sled and pulling it via a 200-ft nylon rope to a sandbagged detonation area. 

Commercially acceptable airbag systems should comprise an inflatable cushion, impact sensors, an ignition system, and an inflating propellant housed within an appropriate container or module with electronic connectivity. Table 11.6 lists the key features that the airbag itself should possess, apart from acceptable cost of course.
