Abstract: An electronic controller applies a braking force to selected wheels when sudden tire rupture is detected. A tire rupture signal indicative of whether a tire on the vehicle has ruptured is generated. Signals corresponding to a desired trajectory of the and the actual trajectory of the vehicle are calculated. Corresponding brake actuator signals are generated and applied to appropriate brakes of the vehicle, controlling the actual trajectory of the vehicle.

Abstract: A technique for estimating a traction characteristic of a surface under a moving vehicle, such as the coefficient of friction of the surface. The traction characteristic can be estimated by generating a torque signal representative of at least an estimate of the amount of torque applied to the driven wheels of the vehicle. A load signal representative of at least an estimate of the load or weight applied to the driven wheels also is generated. The value of the torque signal is divided by the value of the load signal in order to generate a characteristic signal. Depending on the amount of slippage between the driven and non-driven wheels of the vehicle, the characteristic signal can be stored in order to provide an estimate of the traction characteristic of the surface in real time.

Abstract: A device for assisting in the toilet training. The device includes a bowl for receiving human waste as well as an electrical assembly. The electrical assembly includes two pins extending through the bowl, an elastomeric buffer, two contacts interconnected to a resistance sensor, and a melody generator. The buffer provides a solderless electrical connection between the corresponding pins and contacts. When the electrical resistance between the pins decreases, the resistance sensor detects the decrease in resistance between the two pins and contacts and delivers an activation signal to the melody generator.

Abstract: Techniques for controlling the spin of driven wheels of a vehicle also including non-driven wheels and an engine controlled by a spark angle and/or throttle position. The spark angle is controlled by a signal responsive to a slip error signal and a slip error derivative signal in order to alter the spark angle in a manner that controls the spin of the driven wheels. The throttle position is controlled by a throttle position control signal that is responsive to a slip error signal, a slip error derivative signal, and a slip error integration signal, in order to adjust the throttle position in a manner that controls the spin of the driven wheels. Wheel spin also can be controlled by the combination of a spark angle control signal and a throttle position control signal.

Abstract: Techniques for controlling the spin of driven wheels of a vehicle being driven over a surface, the vehicle also including nondriven wheels and an engine having a fuel system for varying engine torque. A characteristic signal representative of at least an estimate of the value of a traction characteristic of a surface under the vehicle is generated. A drive signal having a value dependent on the value of the characteristic signal is then generated. The engine torque is varied in response to the drive signal in order to control the spin of the driven wheels of the vehicle.
