Abstract: A vehicle brake control system includes a brake booster divided into a constant pressure chamber permanently communicating with a vacuum source, and a variable pressure chamber selectively communicating with the constant pressure chamber. The brake booster includes a first servo mechanism designed to develop a differential pressure between the two chambers, and a second servo mechanism. A master cylinder is operatively connected to the brake booster to create hydraulic pressure in response to the output of the brake booster, and hydraulic lines connect the master cylinder and the wheel cylinders. Pressure charging valves allow and block communication between the master and the wheel cylinders. Pressure relief valves between the pressure charging valves and the wheel cylinders selectively release the hydraulic pressure from the hydraulic lines.

Abstract: The inventive passive damping system features the unique harmonization of: (i) a constrained-layer damping subsystem (wherein an elastomer serves as constrained damping material); (ii) an entrained damping subsystem (wherein a particulate serves as entrained damping material); and, (iii) a tuned damping subsystem (wherein modal properties of certain inventive components have been selectively varied in accordance with anticipated resonance frequencies). The invention's effectiveness is aggregative; the total loss factor for the inventive damping system equals the sum of the individual loss factors for the damping subsystems. Consequently, the invention affords a high loss factor in a broad frequency range. Especially in applications involving control of extremely high vibrations, the inventive damping methodology is more efficient and economical than are common damping methodologies.

Abstract: A spring element is made of a spring material and is formed into a generally elliptical shape. Two mounting pins extend in a normal direction through parallel relatively short segments of said elliptically-shaped spring element. The mounting pins are substantially aligned with the shorter of the two axis of the elliptically-shaped spring element so as to extend both inwardly and outwardly of said elliptically-shaped spring element. An elastomeric coating is applied around substantially all of the spring elements and a pair of blocks, each of which surrounds one of the mounting pins receives one of the mounting pins. A number of spring elements are joined together by two parallel, spaced-apart coupling links which contain cavities therein to receive one of the blocks of each of the spring elements.

Abstract: A safety brake device for a stroller is disclosed. The brake device will automatically preclude the movement of the stroller when the user releases the brake handle. The brake handle is movably mounted to the stroller for being pushed down during manual propulsion of the stroller. A pulling wire connects to the brake handle for operating a brake assembly incorporating with the wheels. The brake handle is movable between a first and a second positions. In the first position without being handled by the user, the brake assembly precludes the rotation of the wheels. In the second position where the brake handle is pushed down by the user, the pulling wire actuates the brake assembly to release the brake and enables rotation of the wheels. When the user leaves the stroller, the brake handle retrieves to the first position, then the wheels are braked and precluded from rotation.
