摘要： An electronic controller switch (90) is disclosed for authorizing use of controlled devices. The electronic controller switch includes memory (112) for storing a plurality of data strings unique to the particular controlled device with which the electronic controller switch is used. Each data string includes an access code, a validation data bit, and a user time data value. A user provides an input code to the controller via a standard infrared transmitter (134) and an infrared receiver (130) coupled to the controller. In response to the input code provided by the user, a microprocessor (106) searches the memory to determine whether any of the data strings includes a corresponding access code. If a corresponding access code is found and the validation data bit of its data string is not set, then the user has provided a valid input code and will be authorized to use the controlled device (102). If the validation data bit is set, which indicates that the input code provided by the user has been previously used, the user will not be authorized. When the microprocessor determines that a user is authorized, the microprocessor will provide the use time data value of the data string to a timer (116), thereby to control the time period for which the user is authorized. Different data strings are provided with time data values corresponding to different duration time periods.

摘要翻译： 公开了一种用于授权使用受控设备的电子控制器开关（90）。 电子控制器开关包括用于存储使用电子控制器开关的特定受控设备特有的多个数据串的存储器（112）。 每个数据串包括访问代码，验证数据位和用户时间数据值。 用户通过耦合到控制器的标准红外发射器（134）和红外接收器（130）向控制器提供输入代码。 响应于由用户提供的输入代码，微处理器（106）搜索存储器以确定数据串中的任何一个是否包括相应的访​​问代码。 如果找到对应的访问代码并且未设置其数据串的验证数据位，则用户提供了有效的输入代码，并且将被授权使用受控设备（102）。 如果验证数据位被设置，这表示用户提供的输入代码已经被使用，则不会授权用户。 当微处理器确定用户被授权时，微处理器将向定时器（116）提供数据串的使用时间数据值，从而控制用户被授权的时间段。 不同的数据串被提供有对应于不同持续时间的时间数据值。
