Abstract

Provided is a pillow having an apparatus for determining a sleeping state under an unrestricted non-self-awareness condition. The apparatus includes a sensor for detecting analog bio-information on a pulse, breathing, body movement, snore. bruxism for a user putting his/her head on the pillow, a signal processing unit for filtering off and amplifying the analog bio-information detected by the sensor, and a control unit for converting the analog bio-information output from the signal processing unit into a digital signal, storing the digital signal therein, extracting parameters from the detected bio-information to provide a sleeping status as a quantitative indicator. The sensor is installed in the pillow. The sensor is inserted into a pad type housing so that the sensor does not directly contact an interior material of the pillow. The housing is provided on an upper portion of the pillow so that minute vibration and movement of the user'"'"'s head, which are incurred by the user'"'"'s breathing, pulse, body movement, and snore, is effectively transferred to the sensor.

Claims

1. A pillow having an apparatus for determining a sleeping state under an unrestricted non-self-awareness condition, the apparatus comprising:

a sensor for detecting analog bio-information on a pulse, breathing, body movement, snore, bruxism for a user putting his/her head on the pillow;

a signal processing unit for filtering off and amplifying the analog bio-information detected by the sensor; and

a control unit for converting the analog bio-information output from the signal processing unit into a digital signal, storing the digital signal therein, extracting parameters from the detected bio-information to provide a sleeping status as a quantitative indicator,

wherein the sensor is installed in the pillow;

the sensor is inserted into a pad type housing so that the sensor does not directly contact an interior material of the pillow; and

the housing is provided on an upper portion of the pillow so that minute vibration and movement of the user'"'"'s head, which are incurred by the user'"'"'s breathing, pulse, body movement, and snore, is effectively transferred to the sensor.

2. The pillow of claim 1, wherein the sensor is fixed on a central portion of the pad type housing and is selected from the group consisting of a piezoelectric ceramic, a piezoelectric film, a piezoelectric cable, a resistive pressure sensor, a load cell, and an acceleration sensor.

3. The pillow of claim 1, wherein the housing comprises upper and lower pads for protecting the sensor and a fixing support for fixing the upper and lower pads, wherein the housing is formed of aluminum or plastic so that minute vibration and pressure variation signals during the user'"'"'s sleep is efficiently transferred to the sensor and the sensor is fixed at the central portion of the housing.

4. The pillow of claim 3, wherein an elastic member is provided between the sensor and the upper pad so that minute vibration and pressure variations are efficiently transferred from the upper pad to the sensor, wherein the elastic member is formed of rubber.
