An enclosed receptacle comprising: a receptacle portion defining a reservoir; a lid mounted relative to the receptacle and configured to pivotally move between opened and closed positions; a power supply; a lifting mechanism configured to move the lid between the opened and closed positions; at least one light emitter located at an upper end of the receptacle configured to transmit an encrypted, pulsed light signal; a controller configured to control operation of the lid; characterized in that the receptacle further comprises: at least one light receiver located at the upper end of the receptacle configured to receive the encrypted, pulsed light signal; and in that the controller comprises: at least one lid movement trigger module configured to detect whether the at least one light receiver has received the encrypted, pulsed light signal a predetermined number of times and to issue a command to the controller to open the lid; an increased sensitivity module configured to increase the sensitivity of the at least one light receiver by increasing frequency and/or amperage of the encrypted, pulsed light signal. a receptacle portion defining a reservoir; a lid mounted relative to the receptacle and configured to pivotally move between opened and closed positions; a power supply; a lifting mechanism configured to move the lid between the opened and closed positions; at least one light emitter located at an upper end of the receptacle configured to transmit an encrypted, pulsed light signal; a controller configured to control operation of the lid; characterized in that the receptacle further comprises: at least one light receiver located at the upper end of the receptacle configured to receive the encrypted, pulsed light signal; and in that the controller comprises: at least one lid movement trigger module configured to detect whether the at least one light receiver has received the encrypted, pulsed light signal a predetermined number of times and to issue a command to the controller to open the lid; an increased sensitivity module configured to increase the sensitivity of the at least one light receiver by increasing frequency and/or amperage of the encrypted, pulsed light signal. at least one light receiver located at the upper end of the receptacle configured to receive the encrypted, pulsed light signal; and in that the controller comprises: at least one lid movement trigger module configured to detect whether the at least one light receiver has received the encrypted, pulsed light signal a predetermined number of times and to issue a command to the controller to open the lid; an increased sensitivity module configured to increase the sensitivity of the at least one light receiver by increasing frequency and/or amperage of the encrypted, pulsed light signal. at least one lid movement trigger module configured to detect whether the at least one light receiver has received the encrypted, pulsed light signal a predetermined number of times and to issue a command to the controller to open the lid; an increased sensitivity module configured to increase the sensitivity of the at least one light receiver by increasing frequency and/or amperage of the encrypted, pulsed light signal.
