Apparatus for analyzing a sleep structure according to non-constrained weight detection

An apparatus for analyzing a sleep structure according to non-restrictive weight detection, the apparatus comprising:

• one or more weight detection sensors installed in equipment, which can be slept in, and configured to detect a weight of a target person in a non-restrictive manner;
• amplifiers for amplifying signals measured by the weight detection sensors;
• low-pass filters for outputting low-pass filtered signals that belong to signals amplified by the amplifiers;
• high-pass filters for outputting high-pass filtered signals that belong to the signals amplified by the amplifiers;
• a multiplexer for selecting any one from among the outputs of the low-pass filters and the high-pass filters;
• a controller configured to detect information about the target person's sleep from the low-pass filtered signals and the high-pass filtered signals, which belong to outputs of the high-pass filters and the low-pass filters, respectively, and are input through the multiplexer, and determine the target person's sleeping pattern;
• and
• a display unit for displaying determination results of the controller.
