    • A limited-use appliance is disclosed which has at least one input device for generating an input signal and a controller associated with the input device and receiving the input signal. The controller initiates at least one limited-use function of the appliance upon receipt of the input signal. A test device is maintained by the controller, and has a predetermined criteria which determines whether the input signal should be sent on to the controller or not. A method for pre-installing an appliance is also disclosed and includes the steps of pre-installing an appliance with a controller, wherein the controller operates the appliance in a limited manner. An input device from a group of input devices is associated with the controller, wherein the input device generates an input signal to operate the appliance. And the pre-determined criteria maintained by the controller is tested such that the input signal from the controller is blocked when the pre-determined criteria is met. The appliance is most likely a garage door operator, but it could be any large appliance that is installed prior to the purchase of a home or facility.
    • 公开了一种使用有限的设备,其具有用于产生输入信号的至少一个输入设备和与输入设备相关联并接收输入信号的控制器。 控制器在接收到输入信号时启动设备的至少一个有限使用功能。 测试装置由控制器维护,并且具有确定输入信号是否应发送到控制器的预定标准。 还公开了用于预安装设备的方法,并且包括以下步骤:用控制器预安装设备,其中控制器以有限的方式操作设备。 来自一组输入设备的输入设备与控制器相关联,其中输入设备产生用于操作设备的输入信号。 并且测试由控制器保持的预定标准,使得当满足预定标准时来自控制器的输入信号被阻止。 该设备最有可能是车库门操作员,但它可以是在购买家庭或设施之前安装的任何大型设备。

    • An operator system and related methods (10) for sensing forces on a movable barrier (12) includes a motor (52), a trolley (30), and a trolley arm (34) having a first end slidably supported by the trolley (38) and a second end coupled to the movable barrier. The motor moves the trolley arm which in turn moves the movable barrier. A force detection mechanism (68) is coupled to the motor to determine a first component force value applied by the motor. A controller (54) receives the first component force value and determines a detected force value by scaling the first component force value with a second component force value derived from an angular position of the trolley arm's first end with respect to the trolley. The angular position of the trolley arm may be fixed or variable. An angle potentiometer (72) is coupled to the trolley arm to generate an angle signal for use as the second component force value when the trolley arm's angular position is allowed to vary.
    • 用于感测可移动屏障(12)上的力的操作者系统和相关方法(10)包括电动机(52),手推车(30)和手推车臂(34),其具有由手推车(38)可滑动地支撑的第一端 )和耦合到可移动屏障的第二端。 电动机移动手推车臂,继而移动可动挡板。 力检测机构(68)联接到电动机以确定由电动机施加的第一分量力值。 控制器(54)接收第一分量力值并且通过使用从滑架臂的第一端相对于台车的角位置导出的第二分力来缩放第一分力。 手推车臂的角度位置可以是固定的或可变的。 角电位计(72)被连接到台车臂上以产生一个角度信号,用于当滑车臂的角位置被允许变化时用作第二分力。
