Abstract: A windbreaker for a motorcycle prevents airflow between the front wheel assembly and the fairing connected to the handlebars, by flexibly connecting to the handlebars and the crash bars. An indentation allows airflow to cool the engine. Releasable connectors allow proper turning of the front wheel, even if mis-mounted.

Abstract: A hardware modeling system 10 simulates portions of electrical circuits 16, 18 utilizing actual hardware components in the simulation. Access to these hardware modeling elements 16, 18 is provided on a shared basis to plural workstations 14. Simulation vectors for plural users may be stored discontiguously in a first memory 26 and a single user's vectors are transferred to a second memory 28 for streaming to the elements 16, 18. An optional timing analyzer and memory circuit 34 periodically samples outputs from pins of the hardware modeling elements to provide timing information on the response of such elements. High impedance testing and bus contention detection is performed on the pins of the hardware modeling elements. Clocking signals applied to the hardware modeling elements are adjustable and may be set at extremely high frequencies. A special gating circuit 292 accesses each pin of the hardware modeling elements and incorporates one or more of the above features.

Abstract: A cable winch control having means for sensing the magnitude of the load in elation to the torque being delivered by the power means to the winding drum. The sensed signal is fed back to a manual controller for the drum winding means, to alert the operator to dangerous load situations that could damage the equipment or break the cable. The feedback signal exerts a restraining force on the controller opposing movement thereof, from a neutral "low-load" position to either the "wind-in" or "wind-out" condition. Therefore, the feedback signal has a fail-safe characteristic that prevents runaway movement of the controller in either direction.
