Abstract: Computer-implemented methods and apparatus, including computer program products, implement techniques for validating and correcting structured electronic documents. The techniques include identifying a structural aspect of a structured electronic document that fails to conform to rules of a markup language format. One or more changes are suggested that would correct the identified structural aspect. User input is received selecting a change of the suggested changes. The selected change is applied to the structured electronic document. The rules are associated with the structured electronic document.

Abstract: An adjustable dumbbell assembly of the type including two sets of weights, each including a radial opening extending from a central area to a peripheral area and at least one transversely extending opening in the central area communicating with said radial opening, and a weight supporting assembly operable to selectively connect and disconnect the two sets of weights thereto on opposite sides of a centrally located handle. The weight supporting assembly on each side includes a fixed weight supporting structure, movable weight selector structure, and manually turnable actuating structure. The structures are interrelated with respect to one another, so that when the fixed structure is in an operative position with respect to the weights, manually turning the actuating structure in one direction moves the selector structure in one direction and manually turning the actuating structure in an opposite direction moves the selector structure in the opposite direction.

Abstract: A vehicle stability enhancement system that is adapted for an estimated driver workload. The system includes a driver workload estimation processor that estimates the driver workload based on certain factors, such as the vehicle speed or driver-behavior factors. The driver workload estimation is used to adjust the damping ratio and natural frequency in dynamic filters in a command interpreter to adjust a desired yaw rate signal and a desired side-slip signal. The driver workload estimation is also used to generate a yaw rate multiplication factor and a side-slip multiplication factor that modify a yaw rate stability signal and a side-slip stability signal in a feedback control processor that generates a stability control signal.
