Abstract
Abstract A method for obtaining an acceleration or deceleration signal from a signal proportional to the speed, consisting of storing the most recently ascertained n changes in a memory, wherein upon ascertainment of a new change to be stored in memory, the change which has been stored the longest is erased, and a deceleration or acceleration signal is formed by addition from the stored n changes, each time at intervals of ΔT. Furthermore, in the method according to the invention, the presence of a deceleration or acceleration exceeding the threshold is recognized earlier.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
124 words
A method for obtaining an acceleration or deceleration signal from a signal sensor proportional to a speed, comprising measuring at successive times, of which adjacent times are at a constant interval of ΔT from one another, the change of the speed signal relative to the particular speed signal present at the foregoing time and the acceleration or deceleration signal obtained by means of addition of a predetermined number of successive changes, storing each measured change is stored in a memory having at least n memory possibilities for these changes, obtaining a signal at intervals of ΔT of the acceleration or deceleration signal from the particular n changes most recently stored and erasing at intervals of ΔT the particular change stored earliest in the memory.
Claim 2
Independent Claim
124 words
A method for obtaining an acceleration or deceleration signal from a signal sensor proportional to a speed, comprising measuring at successive times, of which adjacent times are at a constant interval of ΔT from one another, the change of the speed signal relative to the particular speed signal present at the foregoing time and the acceleration or deceleration signal obtained by means of addition of a predetermined number of successive changes, storing each measured change is stored in a memory having at least n memory possibilities for these changes, obtaining a signal at intervals of ΔT of the acceleration or deceleration signal from the particular n changes most recently stored and erasing at intervals of ΔT the particular change stored earliest in the memory.
Claim 3
Dependent Claim
24 words
A method as defined by claim 1, wherein in order to form the acceleration or deceleration signal the n stored values are added up.
Claim 4
Dependent Claim
43 words
A method as defined by claim 1, wherein in order to form the acceleration or deceleration signal the newly obtained mth change is added and the (m-n)th signal is subtracted from the acceleration or deceleration signal obtained and stored at the foregoing time.
Claim 5
Dependent Claim
100 words
A method as defined by claim 1, wherein at successive times, of which adjacent times are at constant intervals of ΔT from one another, the change of the acceleration or deceleration signal is ascertained relative to the acceleration or deceleration signal present at the foregoing time, that each ascertained change is stored in a further memory having at least n memory possibilities for these changes, that at intervals of ΔT the acceleration or deceleration change signal is obtained from the n changes most recently stored and that at intervals of ΔT the change stored earliest in the memory is erased.
Claim 6
Dependent Claim
25 words
A method as defined by claim 4, wherein in order to form the acceleration or deceleration change signal the n stored values are added up.
Claim 7
Dependent Claim
45 words
A method as defined by claim 4, wherein in order to form the acceleration or deceleration change signal the newly obtained mth change is added and the (m-n)th signal is subtracted from the acceleration or deceleration change signal obtained and stored at the foregoing time.
Claim 8
Dependent Claim
128 words
Apparatus for obtaining an acceleration or deceleration signal from a signal sensor proportional to a speed, comprising means measuring at successive times, of which adjacent times are at a constant interval of ΔT from one another, the change of the speed signal relative to the particular speed signal present at the foregoing time and the acceleration or deceleration signal is obtained by means of addition of a predetermined number of successive changes, means storing each measured change is stored in a memory having at least n memory possibilities for these changes, means obtaining a signal at intervals of ΔT the acceleration or deceleration signal from the particular n changes most recently stored and means erasing at intervals of ΔT of the particular change stored earliest in the memory.
Claim 9
Dependent Claim
128 words
Apparatus for obtaining an acceleration or deceleration signal from a signal sensor proportional to a speed, comprising means measuring at successive times, of which adjacent times are at a constant interval of ΔT from one another, the change of the speed signal relative to the particular speed signal present at the foregoing time and the acceleration or deceleration signal is obtained by means of addition of a predetermined number of successive changes, means storing each measured change is stored in a memory having at least n memory possibilities for these changes, means obtaining a signal at intervals of ΔT the acceleration or deceleration signal from the particular n changes most recently stored and means erasing at intervals of ΔT of the particular change stored earliest in the memory.
Claim 10
Dependent Claim
22 words
Apparatus as defined by claim 7, wherein means storing the n values are added up to derive the acceleration or deceleration signal.
