Abstract
Abstract A controlled device is disclosed for allowing a parent to control the use of an appliance by a child. The system includes a plurality of user cards, one of which is assigned to each child. A control device is interconnected with the circuitry of the appliance for actuating and deactuating the controlled appliance. The amount of time allotted to each child can be stored in the memory of the control device. The control device is responsive to input from the children's user cards and actuates the controlled appliance when the time allotted to such user is greater than zero. Once the controlled appliance is actuated, the time allotted to the then current user is decremented until the appliance is deactuated. When the time alloted to the then current user reaches zero, the control device will automatically deactuate the controlled appliance and that child cannot use the appliance until more time is allotted to him or her. The parent is given a master card which allows him to manually increment or decrement the time allotted to each child user. Thus, the device may be used to positively reinforce desired behavior and to discourage undesired behavior.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
196 words
A device for allowing a parent to control the use of an appliance by one or more children comprising: (a) a plurality of child user cards, each encoded with a different user identification code; (b) control means responsive to input of a user identification code from a valid user card for actuating the controlled appliance, the control means including: 1) a memory device for storing the amount of actual user time allotted individually to each user; 2) card reading means for allowing a user to input his user identification code; 3) means for actuating the controlled appliance when amount of actual user time allotted to such user is greater than zero; 4) tabulating means for automatically decrementing the amount of actual user time allotted to the then current user once the controlled appliance is actuated until the appliance is deactuated; 5) means for deactuating the controlled appliance when the amount of actual user time allotted to the then current user reaches zero; and 6) programming means for allowing an administrator to manually increment or decrement the amount of actual user time previously allotted to any user to positively reinforce desired behavior and to discourage undesired behavior.
Claim 2
Independent Claim
196 words
A device for allowing a parent to control the use of an appliance by one or more children comprising: (a) a plurality of child user cards, each encoded with a different user identification code; (b) control means responsive to input of a user identification code from a valid user card for actuating the controlled appliance, the control means including: 1) a memory device for storing the amount of actual user time allotted individually to each user; 2) card reading means for allowing a user to input his user identification code; 3) means for actuating the controlled appliance when amount of actual user time allotted to such user is greater than zero; 4) tabulating means for automatically decrementing the amount of actual user time allotted to the then current user once the controlled appliance is actuated until the appliance is deactuated; 5) means for deactuating the controlled appliance when the amount of actual user time allotted to the then current user reaches zero; and 6) programming means for allowing an administrator to manually increment or decrement the amount of actual user time previously allotted to any user to positively reinforce desired behavior and to discourage undesired behavior.
Claim 3
Dependent Claim
41 words
The control device of claim 1 wherein the control means further includes disabling means for enabling and disabling the controlled appliance at predetermined times, which disabling means overrides the actuating means and renders all user cards invalid during the disabled periods.
Claim 4
Dependent Claim
25 words
The control device of claim 1 wherein the control means further includes means for automatically incrementing the time allotted to each user at predetermined times.
Claim 5
Independent Claim
304 words
A device for allowing one person, and administrator, to control the use of an appliance by a plurality of users comprising: (a) plurality of user cards, each encoded with a discrete user identification code; (b) control means responsive to input of a user identification code from a valid user card for actuating the controlled appliance, the control means including: (1) memory means for storing the amount of time allotted to each user; (2) a control flag register having a plurality of control flags, one corresponding to each of the users, which flags are set to indicate that the corresponding user has time allotted and which flags are cleared to indicate that the corresponding user has no time allotted; (3) a user flag register having a plurality of user flags, one corresponding to each of the users, which user flags are set to indicate that the corresponding user is currently using the appliance, and which flags are cleared to indicate that the corresponding user is not currently using the appliance; (4) card reading means for allowing a user to input his user identification code into the control means; (5) processing means including: (a) means responsive to input of a user identification code for scanning the control flag register and, when the corresponding control flag is set, for actuating the controlled appliance and setting the corresponding user flag; (b) means for scanning the user flag register at predetermined intervals and for decrementing time equal to the predetermined interval from each user whose corresponding user flag is set; (c) means for deactuating the controlled appliance and for clearing the corresponding control flag and all of the user flags when the time allotted to the then current users reaches zero; and (6) programming means for allowing the administrator to program the amount of time allotted to each user.
Claim 6
Independent Claim
304 words
A device for allowing one person, and administrator, to control the use of an appliance by a plurality of users comprising: (a) plurality of user cards, each encoded with a discrete user identification code; (b) control means responsive to input of a user identification code from a valid user card for actuating the controlled appliance, the control means including: (1) memory means for storing the amount of time allotted to each user; (2) a control flag register having a plurality of control flags, one corresponding to each of the users, which flags are set to indicate that the corresponding user has time allotted and which flags are cleared to indicate that the corresponding user has no time allotted; (3) a user flag register having a plurality of user flags, one corresponding to each of the users, which user flags are set to indicate that the corresponding user is currently using the appliance, and which flags are cleared to indicate that the corresponding user is not currently using the appliance; (4) card reading means for allowing a user to input his user identification code into the control means; (5) processing means including: (a) means responsive to input of a user identification code for scanning the control flag register and, when the corresponding control flag is set, for actuating the controlled appliance and setting the corresponding user flag; (b) means for scanning the user flag register at predetermined intervals and for decrementing time equal to the predetermined interval from each user whose corresponding user flag is set; (c) means for deactuating the controlled appliance and for clearing the corresponding control flag and all of the user flags when the time allotted to the then current users reaches zero; and (6) programming means for allowing the administrator to program the amount of time allotted to each user.
