Abstract
Abstract Validator-controlled apparatus responsive to the inspection and validation of a plaque as genuine cooperating with a timer to control the power supply to and operation of a plurality of electrical components for one or consecutive predetermined periods. In an illustrative application of the apparatus, the validator inspects and authenticates a coded plaque of paper currency or a coded card as a prerequisite to the control and use of a room for a measured period of time equipped with one or more electrical components. One of the controlled components is a lock for the room door or barrier which re-locks after entrance of the patron or patrons and remains locked from its exterior but is manually releasable from the interior at any time. The apparatus includes provision for disabling the plaque validator and the door lock during the decrement of an existing predetermined time period.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
182 words
Mechanism for controlling the use of a facility for a predetermined time period in response to receipt and authentication of a valid encoded plaque comprising: inspection and validator means operable to inspect an encoded plaque of paper currency and to provide an output signal in response to inspection and authentication of a plaque of paper currency; electronic timer means activated by said output signal and operable to measure a plurality of time periods of different preselected duration; a plurality of power operated components; means connecting said timer means, said inspection and validator means and said power operated components in circuit for use for a respective one of said predetermined time periods upon receipt of an output signal from said plaque inspection and validator means; and means for disabling said plaque inspection and validator means to receive another plaque during the decrement of an activated predetermined time period and including means for delaying the operation of said disabling means for a short period thereby to provide time for the insertion and processing of an additional plaque into said plaque inspection and validating means.
Claim 2
Dependent Claim
182 words
Mechanism for controlling the use of a facility for a predetermined time period in response to receipt and authentication of a valid encoded plaque comprising: inspection and validator means operable to inspect an encoded plaque of paper currency and to provide an output signal in response to inspection and authentication of a plaque of paper currency; electronic timer means activated by said output signal and operable to measure a plurality of time periods of different preselected duration; a plurality of power operated components; means connecting said timer means, said inspection and validator means and said power operated components in circuit for use for a respective one of said predetermined time periods upon receipt of an output signal from said plaque inspection and validator means; and means for disabling said plaque inspection and validator means to receive another plaque during the decrement of an activated predetermined time period and including means for delaying the operation of said disabling means for a short period thereby to provide time for the insertion and processing of an additional plaque into said plaque inspection and validating means.
Claim 3
Dependent Claim
43 words
Mechanism as defined in claim 1 characterized in that said power components include means normally disenabling said mechanism for use except during the decrement of a relatively long predetermined time period initiated by at least one output signal from said plaque validator means.
Claim 4
Dependent Claim
54 words
Mechanism as defined in claim 1 characterized in that said validator disenabling means includes means for delaying the operation of said disabling means for successive short periods thereby to permit insertion and processing of successive plaques so long as a plaque insertion occurs during the decrement of the associated one of said short periods.
Claim 5
Dependent Claim
38 words
Mechanism as defined in claim 3 characterized in the provision of means for reenabling said plaque validator means after the complete decrement of a relatively long one of said different predetermined time periods initiated by said output signal.
Claim 6
Dependent Claim
42 words
Mechanism as defined in claim 3 characterized in the provision of means for reenabling said plaque validator means after completion of the decrement of the sum of the relatively long predetermined time period initiated by each of a plurality of valid plaques.
Claim 7
Dependent Claim
17 words
Mechanism as defined in claim 1 characterized in that said power components include electrically operated locking means.
Claim 8
Dependent Claim
21 words
Mechanism as defined in claim 6 characterized in that said locking means is in the locking position thereof when not energized.
Claim 9
Dependent Claim
41 words
Mechanism as defined in claim 6 characterized in that said timer means includes means for maintaining said locking means energized and unlocked during said relatively short predetermined period following receipt of a valid plaque by said plaque inspection and validation means.
Claim 10
Dependent Claim
41 words
Mechanism as defined in claim 8 characterized in that said timer means includes means for limiting the energization of said locking means to a small fraction of the period during which power is supplied to other of said power operated components.
