Abstract: To simplify the printing of medical forms, provision is made for a reader of chip cards and a set of chip cards comprising doctor chip cards and patient chip cards. According to the principle of the system, it is provided that the doctor's card will be inserted into the reader as soon as the working day begins, and that this card will set the reader. Subsequently, by introducing patient cards, it is possible to prompt the printing of forms having, at the appropriate places, indications pertaining to the doctor who has issued the prescription and the patient who has received it.

Abstract: A vehicle and vehicle bumper provide protection against other vehicles underriding the vehicle. The bumper uses breakable links which break at a predetermined force. The bumper structure has a pivoting arrangement such that, upon breakage of the breakable links, the pivoting of the bumper tends to lift the rear of the vehicle which is being hit and tends to smash downward on the front end of the impinging vehicle, which might otherwise underride the vehicle having the present bumper. A method of using the bumper to prevent underride includes the smashing down and lifting up features.
