Abstract
Abstract A method for the production of inserts or the like is shown, with a patient or also a healthy person standing/walking/sitting/lying/biting in a defined position and/or movement with the body part to be fitted (foot, buttocks/back, teeth) on/over an electronic measuring arrangement for two- or three-dimensional measurement of the forces (pressures) acting on the measuring arrangement. The output signals of the measuring arrangement corresponding to the pressure-force distribution under the body part in the two- or three-dimensional pattern of the pressure-force distribution are relayed to a computer and compared with a stored set of desired values (wanted or ideal data). The differences between the distribution patterns are transformed into control signals for controlling an apparatus for the manufacture of the inserts or seating furniture surfaces, lounging furniture surfaces, dental prostheses, in such a way that upon addition of the (virtual) pressure force compensation distribution in accordance with the form (height) and/or rigidity of the inserts or the like to be manufactured to the actual pressure force distribution pattern, the desired pressure force distribution pattern essentially results.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
110 words
A method for the production of inserts and the like for a person, comprising the steps of: electronically measuring a spatial pattern of forces applied by the person to a measuring arrangement; producing output signals in correspondence with said measured forces; supplying said output signals to a computer; comparing said supplied output signals in the computer with stored signals corresponding to a stored set of desired values of a force distribution pattern; producing control signals in response to differences between said output signals and said stored signals; controlling apparatus for making the inserts and the like in response to said control signals such that a desired force distribution pattern results.
Claim 2
Independent Claim
110 words
A method for the production of inserts and the like for a person, comprising the steps of: electronically measuring a spatial pattern of forces applied by the person to a measuring arrangement; producing output signals in correspondence with said measured forces; supplying said output signals to a computer; comparing said supplied output signals in the computer with stored signals corresponding to a stored set of desired values of a force distribution pattern; producing control signals in response to differences between said output signals and said stored signals; controlling apparatus for making the inserts and the like in response to said control signals such that a desired force distribution pattern results.
Claim 3
Dependent Claim
129 words
A method according to claim 1; further including the step of applying said forces to a portion of said measuring arrangement by contact of the person with a surface of the measuring arrangement in which a portion of said surface is not contacted by the person; and said step of electronically measuring includes the step of 3-dimensionally scanning distances between said person and portions of said surface of the measuring arrangement that are not contacted by the person by means of distance sensors; said step of producing output signals includes the step of producing output signals by said sensors such that the output signals correspond to a distance pattern between the person and the measuring arrangement and said stored set of desired values correspond to a desired distance pattern.
Claim 4
Dependent Claim
