  • Patent number: 4745564
    Abstract: An apparatus for measuring and recording accelerations or other physical quantities experienced by easily damaged items of commerce such as fruit and electronic computers. A triaxial accelerometer or other suitable sensor produces signals which are sampled by a microprocessor operating according to a program stored in a read-only memory. When the sampled accelerations or other physical quantities exceed a predetermined threshold, samples are stored in a random access memory, along with their times of occurrence. The apparatus provides a serial port for reading out the recorded acceleration data. The data may then be subjected to further processing externally.
