Sleep-posture sensing and monitoring system

摘要

In a system for protecting a user from injury sustained during sleep, a sensing device is operated to automatically monitor orientation or posture of a user during sleep of the user. A signal is transmitted from the sensing device to a control unit, which is operated to activate an appliance so that the appliance generates an alert signal upon detection by the sensing device and control unit of an undesirable orientation or posture of the user.

主权项

1. A sleep-posture sensing system comprising: at least one position or orientation sensor configured to produce a signal encoding information pertaining to an orientation or posture of a user during sleep; and a control unit operatively connected to said at least one position or orientation sensor and operatively connectable to an appliance for changing an operative state of said appliance in response to a signal from said sensor indicating assumption of an undesirable sleeping orientation or posture of the user, said control unit being configured with a time base or clock so as to change the operative state of said appliance only after a predetermined period of time has elapsed after detection of the undesirable sleeping orientation or posture of the user, whereby the user is permitted to sleep for said period of time after the assumption of the undesirable sleeping orientation or posture.
