  • Patent number: 4178871
    Abstract: A control system for hydrofoil craft is one in which control surfaces are moved automatically in response to signals derived from the motion of the craft to stabilize and control the craft. In such systems, a potentially dangerous condition can occur in case of a failure or malfunction in the roll control system. In order to prevent such conditions, two redundant roll sensing devices are provided which normally generate identical signals to actuate the control surfaces to stabilize the rolling motion. In case of a failure or malfunction, the signals provided by the two sensing devices become different. When this occurs, all normal control signals to the control surfaces are terminated; and secondary feedback loops act to position all control surfaces to smoothly land the craft.

  • Patent number: 4038640
    Abstract: A control system for an electronic data processing system minimizes hardwiring and specialized components and circuits and provides bidirectional communication between a data processor within the data processing system and an operator via intermediary binary digital input and output words. A separate aspect is the provision of a master control panel configuration including means for receiving input and output elements having generalized identities, in conjunction with encoder and decoder means interposed in the circuitry and reducing the interconnections between the panel and the data processing system. The control system converts the status of selector switches and momentary switches to signals representing an intermediary input word. The data processor processs and interprets the signals representing the input word and generates appropriate system responses.
