    • An improved alarm system for monitoring movement through a passageway defined by opposing sidewalls. The alarm system has a lower passage indicator disposed toward the lower ends of the sidewalls, an upper passage indicator disposed toward the upper ends of the sidewalls and a control mechanism configured to sound an alarm if the lower passage indicator indicates passage through the passageway and the upper passage indicator does not. In one embodiment, each of the passage indicator comprises transducers that are configured to direct and receive sound waves, such as ultrasound waves, and provide lower and upper ultrasound waves that act as lower and upper barriers. If only the lower barrier is interrupted, indicating a child passing through the passageway, the control mechanism will generate an alarm signal. If both barriers are interrupted, indicating an adult passing through the passageway, the control mechanism will not generate the alarm signal.
    • 一种改进的报警系统,用于监测通过相对侧壁限定的通道的运动。 警报系统具有朝向侧壁的下端设置的下通道指示器,朝向侧壁的上端设置的上通道指示器以及如果下通道指示器指示通过通道而发出报警的控制机构,以及 上通道指示器不。 在一个实施例中,每个通道指示器包括被配置为引导和接收声波(例如超声波)的换能器,并且提供用作下部和上部屏障的较低和较高超声波。 如果只有下障碍物中断,指示孩子通过通道,则控制机构将产生报警信号。 如果两个障碍都中断,表示成年人通过通道,则控制机构不会产生报警信号。

    • An improved alarm system for monitoring movement through a passageway defined by opposing sidewalls comprises a lower passage indicator disposed toward the lower ends of the sidewalls, an upper passage indicator disposed toward the upper ends of the sidewalls and a control mechanism configured to sound an alarm if one of the passage indicators indicates passage through the passageway and the other passage indicator does not. In a preferred embodiment, the alarm system is configured as a pool alarm and each passage indicator comprises an emitter/receiver that emits an infrared beam toward an opposing reflector to provide a lower beam and an upper beam. If only the lower beam is interrupted, indicating a child passing through the passageway, the control mechanism will generate an alarm signal. If both beams are interrupted, indicating an adult passing through the passageway, the control mechanism will not generate the alarm signal.
    • 用于监测通过由相对侧壁限定的通道的运动的改进的报警系统包括朝向侧壁的下端设置的下通道指示器,朝向侧壁的上端设置的上通道指示器,以及配置成发出报警的控制机构 一个通道指示器表示通过通道,另一个通道指示器不通过。 在优选实施例中,警报系统被配置为池警报器,并且每个通道指示器包括发射器/接收器,其向相对的反射器发射红外线束以提供下部光束和上部光束。 如果只有下梁被中断,指示孩子通过通道,则控制机构将产生报警信号。 如果两束都被中断,表示成年人通过通道,则控制机构不会产生报警信号。
