Abstract: A method for execution by a processing module begins with receiving application requirements and parameters. The method continues by generating application code based on the application requirements, the parameters, and the feedback. For a current implementation of the application code, the method continues by entering a loop that begins by selecting an implementation tool in accordance with implementation constraints and a previous implementation result. The loop continues by generating a current implementation result based on an application of the implementation tool, one or more of the application requirements, one or more of the parameters, and the previous implementation. The loop continues by receiving current feedback regarding the current implementation result. The loop continues by determining whether the current implementation result is at a desired level of correctness based on the current feedback.

Abstract: A water needling device has a housing having an intake side and defining a generally horizontal transport direction extending downstream from the intake side. A support in the housing has an upwardly directed foraminous support face. Upstream and downstream reversible winders in the housing spaced apart in the direction flank a plurality of rollers. A textile web passesin the housing along a path starting at the intake, extending over the support face and the rollers, and then downstream out of the housing. A nozzle beam is directed downward at the surface to consolidate the web as it passes over the foraminous face. A threading-in conveyor strand secured to the winders and having a gripper attachable to the textile web extends over at least some of the rollers. This strand is attached at its ends to reversible winders.

Abstract: In a former known hydrodynamic needling device the material web which is meant to be consolidated or finished shall be drawn-in totally or just partly, thus automatically, by an auxiliary material-web drawing-in device. The auxiliary device can work with a frontrunner which is affixed at the beginning of the material web, and which is retracted into the whole machine, or only one part of the non-accessible, if applicable, rollers are driven round by an auxiliary device and the material web is therewith threaded in the provided material-web track.

Abstract: A pedal simulator utilizing springs to provide a brake pedal with a non-linear, progressively increasing response characteristic for pedal travel versus force exerted on the brake pedal similar to a conventional hydraulic braking system. In a preferred embodiment, the pedal simulator is integrated into the housing of an associated master cylinder.

In second and third embodiments, the non-linear, progressively increasing response characteristic is provided by a plurality of cylindrical coil springs.

Abstract: An electrically actuated hydraulic power cylinder for use in a vehicle braking system. The power cylinder includes an electric motor, a rotary-to-linear actuator for converting rotary motion of the electric motor to a linear motion, and a hydraulic cylinder. In a preferred embodiment, the rotary-to-linear actuator is a roller screw assembly. The roller screw assembly converts rotational motion generated by the motor into axial movement of a piston which is disposed within the hydraulic cylinder. The movement of the piston pressurizes a volume of fluid. The pressurized fluid flows through an outlet port connected to either a single wheel brake cylinder or a plurality of wheel brake cylinders, thereby actuating the associated wheel cylinder. In a specific embodiment of the invention, the roller screw assembly is incorporated into the internal structure of the motor for compactness and weight reduction.

The pedal simulator is coupled to a brake pedal, and includes an electrical actuator operatively coupled to the brake pedal to selectively exert a force on the brake pedal. A position sensor is provided for generating a position signal indicative of the position of the brake pedal. A force sensor is provided for generating a force signal indicative of the force exerted upon the brake pedal by a driver. An electronic control unit is provided which has programmed therein a desired relationship between the position signal and the force signal. The electronic control unit determines an actual relationship between the position signal and the force signal and compares the actual relationship thus determined with the desired relationship.

Abstract: An improved electro-hydraulic brake system having features for improving the pedal feel of the system, while further having design features which contribute to the economy of manufacture of certain components of the system. The system provides for an electrically powered normal source of pressurized hydraulic brake fluid, and a manually powered backup source of pressurized hydraulic brake fluid to the vehicle brakes in the event of failure of the normal source. During normal braking, fluid from the backup source is redirected from the vehicle brakes to a pedal simulator. The pedal simulator preferably includes arrangements of spring loaded pistons, expansion volumes, and damping orifices, together with valves selectively controlling the flow of fluid to and from the pedal simulator which provides for an improved pedal feel during vehicle braking.
