Claims18
A method of operating a barrier movement actuating receiver to allow barrier movement activation by users of both semipermanent and temporary access codes and to deny activation to users of temporary access codes after the passage of a predetermined amount of time, wherein the barrier movement actuating receiver is located behind the barrier and remote from a remote access code transmitter and wherein movement of the barrier is controlled by receipt of a valid access code, the method comprising:
- storing in the receiver a semipermanent access code which remains valid until invalidated by user access interaction;
- storing in the receiver a temporary access code which remains valid until the passage of a predetermined period of time;
- receiving a transmitted access signal responsive to a user input access code from the remote access code transmitter;
- activating the barrier actuating receiver to send a barrier activation signal to move the barrier when the received access signal matches a stored signal responsive to a valid stored semipermanent access code and when the received access signal matches a stored signal responsive to a valid stored temporary access code;
- and
- invalidating the temporary access code upon the passage of the predetermined period of time.
A method of operating a barrier movement actuating receiver to allow barrier movement activation by users of both semipermanent and temporary access codes and to deny activation to users of temporary access codes after a predetermined number of uses of the temporary codes, wherein the barrier movement actuating receiver is located behind the barrier and remote from a remote access code transmitter and wherein movement of the barrier is controlled by receipt of a valid access code, the method comprising:
- storing in the receiver a semipermanent access code which remains valid until invalidated by user interaction;
- storing in the receiver a temporary access code which remains valid until after a predetermined number of receptions thereof;
- receiving a transmitted access signal responsive to a user input access code from the remote access code transmitter;
- activating the barrier actuating receiver to send a barrier activation signal to move the barrier when the received access signal matches a stored signal responsive to a valid stored semipermanent access code and when the received access signal matches a stored signal responsive to a valid stored temporary access code;
- and
- invalidating the stored temporary access code after a predetermined number of receptions thereof.
A method of operating a barrier movement actuating receiver to allow barrier movement activation by users of both semipermanent and temporary access codes and to deny activation to users of temporary access codes after the passage of a predetermined amount of time and/or a predetermined number of uses of the temporary codes, wherein the barrier movement actuating receiver is located behind the barrier and remote from a remote access code transmitter and wherein movement of the barrier is controlled by receipt of a valid access code, the method comprising:
- storing in the receiver a semipermanent access code which remains valid until invalidated by user access interaction;
- storing in the receiver a temporary access code which remains valid until the passage of a predetermined period of time and/or after a predetermined number of receptions thereof;
- receiving a transmitted access signal responsive to a user input access code from the remote access code transmitter;
- activating the barrier actuating receiver to send a barrier activation signal to move the barrier when the received access signal matches a stored signal responsive to a valid stored semipermanent access code and when the received access signal matches a stored signal responsive to a valid stored temporary access code;
- and
- invalidating the temporary access code upon the passage of a predetermined period of time and/or after a predetermined number of receptions thereof.
A method of operating a barrier movement actuating receiver to allow barrier movement activation by users of both semipermanent and temporary access codes and to deny activation to users of temporary access codes after expiration of the temporary access code, wherein the barrier movement actuating receiver is located behind the barrier and remote from a remote access code transmitter and wherein movement of the barrier is controlled by receipt of a valid access code, the method comprising:
- storing in the receiver a semipermanent access code which remains valid until invalidated by user access interaction;
- storing in the receiver a temporary access code which remains invalid until it expires;
- receiving a transmitted access signal responsive to a rolling code from the remote access code transmitter, wherein the rolling code includes a portion responsive to a user input access code;
- activating the barrier actuating receiver to send a barrier activation signal to move the barrier when the received access signal matches a stored signal responsive to a valid stored semipermanent access code and when the received access signal matches a stored signal responsive to a valid stored temporary access code;
- and
- invalidating the temporary access code upon the expiration of the temporary access code.
