Devices for aiding resynchronization of body clocks
First Claim
1. A device for aiding resynchronisation of a personal body clock of a traveller, said device comprising a first data series representing the personal body time of the traveller and a second data series representing local time at the destination of the traveller, both said data series having representations of twenty-four hours and being displaceable with respect to each other, the mutual displacement of the data series being carried out with reference to the time of the departure of the traveller and the duration of the journey of the traveller, a readable display for indicating a procedure to resynchronise the personal body clock of the traveller upon said mutual displacement, said procedure comprising controlling exposure of the body of the traveller to daylight.

Abstract
A device for aiding resynchronization of a personal body clock of a traveller, said device comprising a first data series representing the personal body time of the traveller and a second data series representing a local time at the destination of the traveller. Both said data series include representations of twenty-four hours and are displaceable with respect to each other. The mutual displacement of the data series is carried out with reference to the time of the departure of the traveller and the duration of the journey of the traveller to give a readable display of a procedure to resynchronize the personal body clock of the traveller, the procedure comprising controlling exposure of the body of the traveller to daylight.
Certain embodiments of the device are electronic, and are in the form of a calculator or in the form of a program for a calculator or for a wrist watch.

- 13. A method of aiding resynchronisation of a personal body clock of a traveller to assist the re-normalisation of the biorhythm of the traveller when said traveller has completed a relatively long journey including substantial longitudinal displacement, said method comprising the steps of calculating the journey time, amending said journey time to coincide with the arrival time at the journey destination according to local time at the destination, and calculating the difference in exposure to daylight at the destination to prevent the traveller'"'"'s body clock being altered while at said destination.
