Vital signs monitoring system
First Claim
1. A system for determining one or more physiological signals of a user, the system comprising:
- one or more first electrodes configured to;
measure one or more electrical signals of the user;
one or more second electrodes configured to capacitively couple to the one or more first electrodes; and
logic configured to;
generate one or more first signals indicative of a first plurality of changes in capacitive coupling, the first plurality of changes in capacitive coupling being between the one or more first electrodes and the one or more second electrodes;
determine one or more locations of the user based on the one or more first signals;
select a subset of the one or more first electrodes based on the determined one or more locations of the user;
generate one or more second signals indicative of a second plurality of changes in capacitive coupling, the second plurality of changes in capacitive coupling being between the subset of the one or more first electrodes and the one or more second electrodes;
detect the one or more electrical signals of the user using the subset of the one or more first electrodes;
generate one or more third signals indicative of the detected one or more electrical signals of the user; and
determine one or more physiological signals based at least in part on the one or more second signals and the one or more third signals.

Abstract
This relates to a monitoring system capable of measuring a plurality of vital signs. The monitoring system can include a plurality of sensors including, but not limited to, electrodes, piezoelectric sensors, temperature sensors, and accelerometers. The monitoring system can be capable of operating in one or more operation modes such as, for example: capacitance measurement mode, electrical measurement mode, piezoelectric measurement mode, temperature measurement mode, acceleration measurement mode, impedance measurement mode, and standby mode. Based on the measured values, the monitoring system can analyze the user'"'"'s sleep, provide feedback and suggestions to the user, and/or can adjust or control the environmental conditions to improve the user'"'"'s sleep. The monitoring system can further be capable of analyzing the sleep of the user(s) without directly contacting or attaching uncomfortable probes to the user(s) and without having to analyze the sleep in an unknown environment (e.g., a medical facility).
