  • Digital antiskid control system
    Patent number: 4773013
    Abstract: A digital antiskid system for utilization with the braking system of an aircraft. Analog wheel speed signals are digitized and manipulated by a digital processor, under program control, to generate a control signal as a function of the deceleration activity of the wheels. The digital control signal is converted to an analog signal for application to a brake valve to effect application or release of brake pressure.

  • Antiskid system monitoring circuit
    Patent number: 4709223
    Abstract: An efficiency monitor circuit for an antiskid system is provided. The efficiency of the antiskid system is determined by monitoring the antiskid signal as to peak positive and peak negative moves thereof. The difference in these two signals corresponds to the efficiency of the antiskid system. This difference signal is compared to a threshold signal for comparison of the efficiency to a signal corresponding to an acceptable minimum value. Should the efficiency of the antiskid system fail to meet the minimum value, an alarm is activated.
