  • Patent number: 4539754
    Abstract: An auxological measuring apparatus in which there is provided a flat surface which is preferably horizontal, having on it a plate arranged for contact by the feet of a person with his back against the surface and on the case of a horizontal surface lying supine on it, there being a carriage linearly moveable on the surface which can be brought into contact with the person's head. An electronic transducer is associated with the carriage and is arranged to produce an electric signal indicative of the distance between the carriage and the surface and it is associated with electronic circuitry arranged to process the signal and to provide a visible indication of the distance and thus of the height of the person on the surface. A side table may be provided for attachment to the surface so that a person may lie on the surface and the side table with arms outstretched on the table so that an arm span mesurement can be made.

  • Patent number: 4138817
    Abstract: A navigation aid consists of only three, namely first, second, and third indicia bearing members, the latter being respectively a transparent ground speed member bearing a ground speed scale having an origin, a transparent true air speed member bearing a true air speed scale having an origin, and a transparent wind speed and direction member bearing a wind speed scale and a wind direction indicator and having an origin, one of the first and second members bearing above the origin of its scale a compass rose which carries a drift scale which measures the angle between the ground speed scale and the true air speed scale, the three members lying in parallel juxtaposed planes, and only two connections being provided, one of the connections connecting two of the above members together at the origins of their scales by a connection having one rotational degree of freedom, and the other of the connections connecting the remaining member to one of the other two members at the origin of its scale by a connection havin
