Abstract: In some embodiments, a rapid-response active suspension system controls suspension force and position for improving vehicle safety and drivability. The system may interface with various sensors that detect safety critical vehicle states and adjust the suspension of each wheel to improve safety. Pre-crash and collision sensors may notify the active suspension controller of a collision and the stance may be adjusted to improve occupant safety during an impact while maintaining active control of the wheels. Wheel forces may also be controlled to improve the effectiveness of vehicle safety systems such as ABS and ESP in order to improve traction. Also, bi-directional information may be communicated between the active suspension system and other vehicle safety systems such that each system may respond to information provided to the other.

Abstract: Integrated multiple actuator electro-hydraulic systems as well as their methods of use are described. Depending on the particular application, the integrated electro-hydraulic systems may exhibit different frequency responses and/or may be integrated into a single combined unit.

Abstract: A dental impression tray that can be reinforced after the patient bites into the tray. In this particular embodiment, a joint in the tray's posterior is reinforced prior to intraoral placement by a removable wire running through hooks in the tray's rim. Removing the wire after the patient bites imparts flexibility to the joint, and then the tray's frame becomes rigid intraorally when an uncured immobilizing agent previously applied to the joint is cured or is self-cured. The tray's initial rigidity facilitates handling; its subsequent flexibility reduces the frame's plastic memory; and its subsequent rigidity durably locks the tray into a pressure-relieved position, reducing springback distortion.

Abstract: A dental impression tray which can be made flexible after insertion in the patient's mouth. A joint or area of flexibility in the tray's posterior is reinforced prior to intraoral placement by a removable wire running through hooks in the tray's rim. Removing the wire after the patient bites imparts flexibility to the joint, and then the tray's frame becomes less flexible once the impression material cures. The tray's initial rigidity facilitates handling, and its subsequent flexibility reduces the frame's plastic memory, thereby reducing springback distortions.
