Abstract: A microaccelerometer package is provided for housing a microaccelerometer and its associated signal conditioning circuitry. The microaccelerometer package is constructed to be suitably rugged for use in on-board automotive safety control and navigational systems, so as to be capable of isolating the microaccelerometer from extraneous vibrations and package-induced stresses, yet also be small, lightweight, and amenable to mass production techniques. To achieve the above, the microaccelerometer package employs a leadframe which is initially a one-piece strip frame that is integrally molded with a plastic housing to form the primary structure of the package. The leadframe enhances the rigidity of the package so as to result in a high natural frequency of the package, thereby enabling the microaccelerometer to properly respond to the frequency range of interest, while also minimizing the influence of extraneous road and vehicle vibrations on the microaccelerometer.

Abstract: A resilient bumper for protecting vehicles and stationary objects against collisions comprising a plurality of spaced, adjacent fins of flexible resilient material which are so spaced that the fins abut against each other progressively as the result of an impact and thus offer progressively higher resistance as each fin contacts an adjacent fin. The fins are preferably of tough rubber or plastic material having high ultimate elongation at low temperatures, high tear strength over a wide temperature range, and high abrasion resistance.The fins may be disposed on corners of a vehicle or other objects to be protected or may be on flat, circular or other shapes. The fins may be of various shapes and may be offset or staggered relative to each other.
