Embodiment Construction

[0035] figure 1 is a block diagram of the system 100 in the present invention. System 100 includes circadian rhythm engine 102 , sensor subsystem 104 , memory 106 , data processor 108 , and user interface (UI) subsystem 110 .

[0036] The circadian rhythm engine 102 is a module with known functions implemented by hardware, software, or a combination of hardware and software. The circadian rhythm engine 102 runs a model of a person's circadian rhythm. Such circadian rhythm models include, for example, "Addition of a Non-Photic Component to a Light-Based Mathematical Model of the Human Circadian Pacemaker" (Journal of Theoretical Biology 247 , pp. 583-599) with, for example, a digital integrator. Circadian engine 102 receives input from sensor subsystem 104 .

[0037] Sensor subsystem 104 includes one or more light sensors for sensing light incident on the sensor subsystem. Sensor subsystem 104 provides light samples to circadian engine 102 . Each respective light sample o...

Abstract

Information about a person's circadian rhythm is generated in terms of a difference between a reference and a specific circadian time for a specific wall-clock time or in terms of a difference between a special and a specific wall-clock time for a specific circadian time event.

Description

technical field [0001] The present invention relates to a method of generating information about a person's circadian rhythm time cycle for presentation into a graphical user interface. The invention also relates to a system configured to generate information about a person's circadian time cycle for presentation into a graphical user interface. The invention also relates to control software provided as recorded on a computer-readable medium or as an electronic file downloadable on the Internet for configuring a computer to generate Information about a person's circadian time cycle in . Background technique [0002] In humans, a mismatch between the person's internal circadian rhythm and the external night / day rhythm can lead to insomnia, delayed sleep stage disorder (DSPD), (seasonal) affective disorder, etc. Circadian rhythms are controlled by an autonomous rhythmic biological clock in the brain. This biological clock is often referred to as the circadian clock. The ci...
