摘要： This invention provides a solution to the problem of determining how long the peak value detected for the first pulse be kept, and when should it be updated. In infrared communication, the communication distance may vary over time during the transmission. For instance in a mobile infrared telephone the users generally are moving with respect to each other. The signal amplitude changes within a very large range over time and the receiver expected to operate in this environment must also handle a large number of different communication protocols. It uses the instant signal as a basis for adjusting the threshold. The present invention is capable of accepting a wide input dynamic range of signals up to and beyond five orders of magnitude (50 dB). This is accomplished while overcoming the difficulties presented by many communications protocols, by providing a technique in which the output pulse width of an amplified photo detector input is not strongly dependent upon the input signal amplitude.
摘要翻译：本发明提供了确定保持第一脉冲检测到的峰值的时间以及何时需要更新的问题的解决方案。在红外通信中，通信距离可以在传输期间随着时间而变化。例如，在移动红外线电话中，用户通常相对于彼此移动。信号幅度随时间在非常大的范围内变化，并且期望在该环境中操作的接收器也必须处理大量不同的通信协议。它使用即时信号作为调整阈值的基础。本发明能够接受高达五个数量级（50dB）的信号的宽输入动态范围。这是通过提供一种放大的光检测器输入的输出脉冲宽度不依赖于输入信号幅度的技术来克服许多通信协议所呈现的困难而实现的。
