Abstract
Abstract A parking control system includes a central parking meter having coin slots and a binary electronic unit cooperating with a number of indicating members representative respectively of a number of parking spaces. The indicating members are adapted to be activated by the electronic unit depending upon the value of the coin inserted and are arranged to continuously indicate the remaining unexpended parking period for each parking space.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
121 words
A parking control system comprising at least one parking meter having a plurality of coin slots; a plurality of indicating members each arranged for one of a plurality of parking spaces, said indicating members comprising a number of visible signal means arranged to be initially activated in dependence of the magnitude of the parking charge paid for each said parking place and arranged to be successively inactivated as the parking period for which payment has been made expires; and a binary electronic control unit operatively connected with said coin slots and with said indicating members for activating and inactivating same in accordance with the prepaid parking charge as represented by the coins inserted in one or more of said coin slots.
Claim 2
Dependent Claim
121 words
A parking control system comprising at least one parking meter having a plurality of coin slots; a plurality of indicating members each arranged for one of a plurality of parking spaces, said indicating members comprising a number of visible signal means arranged to be initially activated in dependence of the magnitude of the parking charge paid for each said parking place and arranged to be successively inactivated as the parking period for which payment has been made expires; and a binary electronic control unit operatively connected with said coin slots and with said indicating members for activating and inactivating same in accordance with the prepaid parking charge as represented by the coins inserted in one or more of said coin slots.
Claim 3
Dependent Claim
16 words
The parking control system according to claim 1, wherein said visible signal means comprise visible lamps.
Claim 4
Dependent Claim
41 words
The parking control system according to claim 1, wherein said indicating members comprise a plurality of indicating lamps, said indicating lamps being arranged in a row one after the other and arranged to be sequentially deactivated after predetermined periods of time.
Claim 5
Dependent Claim
33 words
The parking control system according to claim 3, including a special indicating lamp arranged to be activated a certain predetermined time after expiration of the parking period for which payment has been made.
Claim 6
Dependent Claim
20 words
The parking control system according to claim 1, wherein a single additional signal means is provided for each parking space.
Claim 7
Dependent Claim
91 words
A parking control centro-meter system including a main unit, n-parking place units and lamp panels, wherein the main unit comprises a coin slot indicator, a converter for coin value conversion to digital impulses, an impulse register M, an impulse comparator and a time base unit controlled by a pacemaker wherein down-counting is performed in the time base unit to given suitable number of impulses in relation to the charge rate to be used in the system and the appearance of the lamp panel determines the programming of the time base unit.
Claim 8
Dependent Claim
91 words
A parking control centro-meter system including a main unit, n-parking place units and lamp panels, wherein the main unit comprises a coin slot indicator, a converter for coin value conversion to digital impulses, an impulse register M, an impulse comparator and a time base unit controlled by a pacemaker wherein down-counting is performed in the time base unit to given suitable number of impulses in relation to the charge rate to be used in the system and the appearance of the lamp panel determines the programming of the time base unit.
Claim 9
Dependent Claim
32 words
A parking control centro-meter system according to claim 6 including a main unit, n-parking place units and lamp panels, wherein each said parking place unit comprises a counter and a register T.
Claim 10
Dependent Claim
97 words
The process of controlling parking with a binary electronic coin operated parking control centro-meter system which includes a main unit and n-parking place units cooperable with an illuminatable control panel which comprises: converting coin value to digital impulse, recording said digital impulses in a binary counter, register M, passing the recorded information from register M to a comparator, distributing the information to a selected parking place unit register T, and comparing impulses from register M and register T and lighting selected control lights when the information in register T is less than the information in register M.
Claim 11
Dependent Claim
97 words
