Abstract
The invention comprises a system that monitors heart activity through embedded ECG sensors in a desk, and desk-related amenities such as a chair, a computer keyboard, a mouse, and a floor mat. The invention also comprises pressure sensors for monitoring a user's presence at the desk. Signals measured from the ECG or pressure sensors are transmitted (in a wired, or wireless fashion) to a computer processing device which applies algorithms to refine the collected signals, and passively estimate the user's ECG.
Claims3
A system for the measurement of heart electrical activity, the system comprising:
- a desk having:
- a. one or more electrically conductive sheets embedded in a top surface of the desk and exposed at the top surface;
- b. one or more interface junctions and a first system of wires that routes electrical activity measured at the one or more conductive sheets to a computer processing device;
- c. an electrical outlet,
- a plurality of secondary sensing devices external to the desk, each having a corresponding secondary system of wires that routes electrical activity to the computer processing device,
- wherein a set of sensing devices comprises the desk and the plurality of secondary sensing devices;
- wherein the computer processing device comprises:
- a. an amplifier;
- b. a central processing unit;
- c. random access memory;
- d. disk storage;
- e. a wireless receiver;
- f. an optocoupler,
- wherein the computer processing device;
- identifies a first subset of the set of sensing devices from which a first plurality of discrete signal components each representing and ECG measurement are retrieved during a first time period;
- retrieves the first plurality of discrete signal components;
- analyzes the first plurality of discrete signal components retrieved from the first subset to determine which of the first plurality of discrete signal components best represents an ECG of a user,
- identifies a second subset of the set of sensing devices from which a second plurality of discrete signal components each representing an ECG measurement are retrieved during a second time period,
- retrieves the second plurality of discrete signal components;
- analyzes the second plurality of discrete signal components retrieved from the second subset to determine which of the second plurality of discrete signal components best represents an ECG of the user;
- and
- outputs ECG data based on the signal components of each of the first plurality and the second plurality of discrete signal components determined to best represent the ECG of the user,
- wherein the first plurality of discrete signal components each correspond to the first time period such that the signal components are generated simultaneously.
