Abstract: An angle measuring device used for measuring the pendulum angle of a cable of a lifting device comprising connection components which utilize measurement value pick-ups and are connected via a cardanic-type joint to axles which are arranged at right angles to one another. To attain high precision of discrimination in measurement, the measurement value pick-ups each comprises a Hall sensor and an associated magnetic element to create a magnetic field detectable by the Hall sensor. An angle of measurement can be attained if the lower connection component is swung and causes a shift in the joint ball around the axle. This results in a change in the position of the magnets relative to the Hall sensors. This change in position results in a change in the detected Hall voltage which after appropriate adjustment can be transformed into an angle measurement.

Abstract: A device that is simply pulled down to touch the head of a child to quickly and accurately determine their height, employs a special extendable and retractable measuring tape that is wall mounted at a specific height over the floor and stays up and out of the normal reach of a small child when not in use. Reading is direct from the tape pulled from a holder. The numbering system of the tape of this device is reversed from tapes conventionally used to measure length, by having the highest number of measurement located at the outer end and decreasing incrementally toward a zero reading nearest the end secured within the holder. The device is properly mounted by extending the tape to the zero reading and securing it at a height on the wall that allows the device, with the tape so extended, to touch the floor directly below it.
