Air Cushion Table with Inkjet Pucks

The air cushion platform is made of matt black aluminium W/ a stabilising honeycombed interior structure. It is equipped W/ profile rails on both sides for the attachment of accessories. The feet which can be adjusted for height allow the platform to be aligned such that it is precisely horizontal. The surface of the platform has rubber edging W/ four holders at the corners to keep it stretched in place. Inside the inkjet pucks there is a micropump motor which generates compressed air. This emerges from the underside of the pucks so that they float across the recording paper on a cushion of air. Power is supplied to the pucks from built-in, but replaceable NiMH replaceable batteries rated at 9 V, 300 mAh. A display of the charge status & the connectors for the charging cable are located on the top of the pucks. The motion of the pucks is recorded by an inkjet onto standard DIN A1 paper lying on a table top. The pucks also contain a conventional print cartridge. Motions recorded for the two pucks can be distinguished by selecting two different colours, red or black. There is also an option to follow the motion W/ the help of a high-speed camera (not included). For this purpose the pucks are equipped W/ bi-coloured LEDs whereby the colours are selectable. Recording is stopped & started by means of an infra-red remote control. The time difference between pulses can be set to between 20 & 100 ms in steps of 5 ms. Two special boards W/ moistening pads provide storage for the pucks after use & prevent the ink from drying out. A lockable, airtight storage box allows the print cartridges to be stored separately from the pucks for longer periods when they are out of use.
