    Abstract: A speed control method of a vehicle including the steps of obtaining a steering angle, a velocity error and a distance error. The velocity and the distance error being determined by mathematical combinations of a GPS position, a required path and speed set points. The steering angle, velocity errors and distance error are applied to fuzzy logic membership functions to produce an output that is applied to a velocity rule base. An output from the velocity rule base is defuzzified to produce a speed signal.

    Abstract: A flow control valve for selectively routing a coolant in a dual-zone heater system is provided. The flow control valve includes a housing and a flow control device. The housing includes an inlet port, a bypass outlet, a front heater outlet, and a rear heater outlet communicating through an internal cavity. The flow control device, which can be a cylinder, sphere, etc., is rotatably positioned in the internal cavity. The flow control device has an axial channel and generally radial aperture. The axial channel transports the coolant received from the inlet port through the flow control device, and the aperture delivers the coolant to one or more of the bypass outlet, the front heater outlet, and the rear heater outlet as the flow control device is rotated. In this way the circuit is not deadheaded.

    Abstract: An elevating scraper adapted to be towed by a tractor to perform earth-grading operations and the like including a vehicle frame, towing means on the frame, and a forwardly open scraper bowl located on the frame and terminating in a lower, forwardly extending scraper edge. An upwardly and rearwardly extending elevating conveyor assembly is mounted on the frame forwardly of the scraper bowl and spaced from the scraper edge, and a support surface is situated closely adjacent the conveyor assembly and cooperates therewith so that material may be elevated by the conveyor assembly and supported during such elevation by the support surface and moved into the scraper bowl. The support surface is perforate so that material of large size will be directed to the scraper bowl while smaller sized material will pass through the support surface to the underlying terrain.

    Abstract: An approach that smoothes a cryptographic function's timing footprint is presented. A processor includes a “function timing smoother” that smoothes out spikes in the amount of time that a particular cryptographic function requires to execute. When a cryptographic function executes, the function timing smoother tracks the amount of time that the cryptographic function executes (current execution time) and compares the time with the amount of time that the same cryptographic function took for a previous execution (previous execution time). When the current execution time is less than the previous execution time, the function timing smoother adds instructions or varies an execution unit's clock speed in order to increase the cryptographic function's current execution time. Using this approach, a malicious user is not able to decipher sensitive information from the cryptographic function's timing footprint.
