  • Patent number: 7848404
    Abstract: A system and method are provided for feed-forward equalization (FFE) in a transmission system. The method accepts a serial stream of input digital data signals. For each input data signal, a temporal sequence of signals is generated. Each of the signals in the temporal sequence is selectively shaped. Shaping map include varying the degree of amplification, modifying the slew rate, or varying the time delay. The contributions of the selectively shaped signals in the temporal sequence are then selectively weighted, and a summed output signal is transmitted.
    Type: Grant

  • Patent number: 7252623
    Abstract: A method is provided wherein when an auxiliary device is being powered by the PTO driveline the PTO clutch is periodically slowly ramped down in pressure until slippage is detected in the clutch. Slippage is determined by monitoring the shaft speed into the clutch as well as the shaft speed downstream of the clutch. By determining the commanded pressure where slippage occurred, the equivalent engine power that is going to the auxiliary function is calculated. With this information, the proportion of the engine load signal that is going to the auxiliary function versus the drive wheels is determined. After slip is detected in the PTO clutch, pressure is ramped back up in the clutch so as to minimize the amount of slippage.
