  • Patent number: 9055905
    Abstract: A method of, and apparatus for, determining if a person operating equipment is experiencing an elevated cognitive load, wherein the person's use of a device at a first time is monitored so as to set a baseline signature. Then, at a later time, the person's use of the device is monitored to determine the person's performance at the second time, as represented by a performance signature. This performance signature can then be compared against the baseline signature to predict whether the person is experiencing an elevated cognitive load.

  • Patent number: 4015703
    Abstract: A transport system or conveyor for flexible items comprises at least two successive groups of three rollers. Each group has a larger diameter roller with which two smaller driven rollers provide nips which are angled to another. The entry nip of a following group is angled with respect to the exit nip of the preceding group such that an item is conveyed through successive nips along a wavy or zig-path. At least one of the two smaller rollers of a group is adjustable to set the entry or exit angle. The system is used in apparatus including a treatment station located between two successive roller groups, the treatment itself inducing a bend in the flexible items which is allowed for by the relative angling of the nips. A particular application is to the moving of photographic papers through a drying station in photographic developing machine.
