Abstract: Pressure transducer means for sensing system pressure and providing a signal proportional thereto is connected to an electrical differentiator which provides an electrical signal which is proportional to the rate of change of system pressure. The rate of change of system pressure electrical signal is then compared to a predetermined reference signal to provide an output electrical signal only when the rate of change signal equals or exceeds the reference signal for a predetermined period of time. The output signal is utilized to actuate a device or sound a warning as may be required.

Abstract: A single analog multiplier is used to obtain the products of many pairs of analog signals. The many pairs of analog signals are connected to the multiplier on a time-sharing basis by cyclically sampling the analog signals and applying them in repetitive sequence to the analog multiplier. Conventional multiplexing techniques are used for this purpose. The successive output signals of the multiplier are then demultiplexed and the amplitudes of the product signals are separately stored to provide the system output. The accuracy of the multiplication is constrained to be very high by repetitively correcting the output of the multiplier according to the product obtained from one or more pairs of analog signals whose products should be fixed and are known references. By suitably operating upon the multiplier outputs, many additional functions such as scaling, filtering, square root extraction, division, etc. may be obtained.

Abstract: A suspension system for the front running skis of a snowmobile. Each ski is yieldingly mounted by leaf springs to a steering rod on a snowmobile, and is capable of guiding the vehicle as well as compensating for terrain irregularities. A piston-cylinder shock absorber is pivotally connected at its lower end to the ski, and the upper end is connected to the snowmobile body by means of a ball and socket coupling to dampen oscillatory movement of the ski.

Abstract: A control system having a plurality of control channels, each of which includes a servo control means having a valve which moves responsively to the application of control signals so as to control the flow of fluid from a source thereof to an output member connected for positioning a load. Electrical transducer means is connected to the control valve to produce an electrical signal which is characteristic of the servo control means. An electrical model which produces an output electrical signal which is characteristic of that signal desired for the servo control valve is provided. The output electrical signals are connected to a comparator for detecting disparity between the signals thus generated and then for providing an output signal which deactivates the particular servo control means wherein the failure has occurred which causes the disparity in the signals being compared.

Abstract: A low pressure fuel injection system for a two cycle internal combustion engine. Fuel is introduced into the combustion chamber during the intake cycle from a cavity in the wall of the combustion chamber supplied with fuel by metering apparatus that controls the flow of fuel in accordance with engine demand. The fuel is compressibly accumulated when the cavity is covered by the piston during the compression and combustion cycles. As the piston moves into the fuel intake cycle, the cavity is opened and the fuel charge is discharged therefrom and swept out by the flow of intake air for subsequent vaporization and combustion.
