Device for waking up a driver and an operator
First Claim
1. An arrangement to awaken a sleeping operator of a vehicle that is controlled by a person, comprising:
- a detection part that is configured to measure movements of a steering control device that belongs to the vehicle to which the driver is to have hand contact for controlling steerage of the vehicle, the detection part comprising a movement detector in or on the control device;
a calculation circuit configured to compare movements of the control device over time; and
an alarm part configured to produce vibrations in surfaces of the control device that are configured for contact with hands of the operator,wherein the calculation circuit is configured to activate the alarm part when no movement of the control device has occurred during a pre-determined period sufficient to indicate that the driver has fallen asleep,wherein all of said detection part, said calculation circuit, and said alarm part are mounted on or are integrated with the control device,wherein the calculation circuit is configured to deactivate the alarm arrangement upon detection of a movement of the control device while the alarm system is activated, andwherein the alarm part is configured to produce vibrations in a direction that is perpendicular to an outer surface of the control device upon which hands of the operator rest during operation.

Abstract
An arrangement to awaken a sleeping driver or operator of a vehicle, a vessel, an aeroplane or any other system that is controlled by a person, includes a detection part that is arranged to measure movements of a control element that belongs to the vehicle with which control element the driver has hand contact, a calculation circuit arranged to compare movements of the control element over time, and an alarm part arranged to produce vibrations in the control element. The calculation circuit is arranged to activate the alarm part when no movement of the control element has occurred during a pre-determined period, which pre-determined period indicates that the driver has fallen asleep, and in that all the parts are mounted on or are integrated with the control element.
