Physiological and behavioral sensors and methods
First Claim
1. A system for measuring physiological and behavioral signals in a human subject, the system comprising:
- a measurement platform for bearing the subject;
at least one of a substantially stationary support or a chair disposed entirely on the platform such that an entire weight of the support or chair is supported by the platform;
at least one force sensor for measuring vertical force imparted by an entire weight of the subject, the at least one force sensor supporting the measurement platform and disposed between the measurement platform and a support surface; and
a signal processor for deriving at least one physiological or behavioral signal, including a ballistocardiogram, from the measured force.

Abstract
In various embodiments, a physiological or behavioral signal is derived from a vertical force resulting from the entire weight of a subject. A system for measuring physiological and behavioral signals in a human subject may include a measurement platform for bearing the subject, at least one force sensor for measuring vertical force imparted by an entire weight of the subject, and a signal processor for deriving at least one physiological or behavioral signal, such as a ballistocardiogram, from the measured force. The force sensor(s) may support the measurement platform and be disposed between the measurement platform and a support surface.

14. A method for measuring physiological and behavioral signals, the method comprising:
-
measuring a vertical force imparted by an entire weight of a human subject having a substantially vertical thorax and disposed upon a measurement platform, the vertical force measured by at least one force sensor that supports the measurement platform and is disposed between the measurement platform and a support surface, at least one of a substantially stationary support or a chair being disposed entirely on the platform such that an entire weight of the support or chair is supported by the platform; and extracting at least one physiological or behavioral signal, including a ballistocardiogram, from the measured vertical force. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23)
