This invention relates to measuring health statistics, particularly relating to a connected surface with sensors. In particular, the invention relates to the measurement of health statistics when the user is standing on the connected surface.
A person spends a significant amount of time each day just preparing for the day. Currently, this time provides little advantage beyond hygiene and cosmetic purposes. Often, a person spends much of this time positioned standing in front of a bathroom sink or other item such that an opportunity to measure health statistics is provided since the user is standing still for an amount of time. Current methods for collecting health statistics as part of the daily routine are largely nonexistent or require the user to deliberately step on a scale to obtain weight and possible body fat percentage. Current methods are limiting in both the health statistics that are measured and the passive nature of data collection.
The invention aims to provide a connected surface with sensors. The connected surface allows a user to stand on the surface to collect data related to health statistics. The user stands on the surface and the various sensors act to measure health statistics about the user. The sensors communicate with the data processing unit, which transmits the data using the transmitter. The data is transmitted to the cloud and/or a data transfer medium. Additionally, the connected surface is comprised in a capacitive coupling user identification system to easily identify the user to the connected surface allowing for use by multiple users.
The health statistics that can be measured are heart rate, blood oxygen saturation, respiration rate, blood pressure, bone density, weight, balance, percent body fat, skin ulcers, stress level, pressure points, electrical heart activity, thermal imaging, and any combination thereof.
Accordingly several advantages are to provide a connected surface, to provide sensors to measure various health statistics, to provide data communication with the cloud and data transfer mediums, and to provide user identification to allow for multiple users. Still further advantages will become apparent from a study of the following descriptions and the accompanying drawings.
The connected surface with sensors is encompassed in a plurality of embodiments that shall be discussed in the present section.

The transmissive pulse oximeter comprises two distinct sides that are parallel with a space separating the two sides creating a measuring site such that a portion of the human body may be inserted between the two sides. The portion of the human body most often inserted in the measuring site is chosen from the group index finger, middle finger, ring finger, pinky finger, thumb, toe, ear lobe, and nose. Two light-emitting diodes (LED) are at least partially contained on the first parallel side creating an emitter. In some embodiments, the two LEDs produce beams of light at different frequencies, which include the range of about 600-750 nanometers (nm) and the range of about 850-1000 nm such that the frequencies produce red and infrared light, respectively. Additionally, the second parallel side comprises a photo detector positioned to be opposite of the emitter such that the photo detector receives the emitted light that passes through the measuring site. The photo detector determines the amount of red and infrared light received, thus determining the amount of red and infrared light absorbed. Accordingly, the amounts of red and infrared light are transmitted to the data processing unit 216 of the connected surface.
Optionally, the data processing unit 216 of the connected surface calculates the ratio of red light to infrared light after the emitted light passes through the measuring site and is received by the photo detector. The calculated ratio is compared to a data bank that relates the calculated ratio to blood oxygen saturation values. The heart rate is further determined by the amount of light absorption of the volume of arterial blood. As the heart pumps blood, the volume of arterial blood increases thus creating a pulsatile change in light absorption. The heart rate is determined by the frequency of pulsatile changes representing heart beats.
Optionally, the reflective pulse oximeter comprises one distinct side, referred to as the contact surface that comprises both the light emitter and the photo detector such that the emitted light travels into the measuring site and is reflected back to the photo detector. The reflective pulse oximeter allows the user to contact only one surface on the connected surface. Accordingly, the reflective pulse oximeter may be contacted by the user during the normal use of the connected surface.
Accordingly, the reflective pulse oximeter transmits the amounts of red and infrared light received by the photo detector via the transmitter to the data processing unit. Similarly, the ratio of red light to infrared light is calculated and compared to a data bank to correlate the ratio to a blood oxygen saturation value. Additionally, the heart rate of the user is determined in the same manner as described for the transmissive pulse oximeter.

Accordingly, the combined embodiment of the piezoelectric transducer and the piezoelectric detector is a piezoelectric transceiver, which performs the functions of both the piezoelectric transducer and the piezoelectric detector comprised in one singular body of piezoelectric material. Conversely, the piezoelectric transducer and the piezoelectric detector utilize separate bodies of piezoelectric material.

Magnetostrictive transducers utilize the magnetostrictive property of the magnetostrictive material to convert the magnetic energy of a magnetic field to ultrasound, which is sound waves above the normal audible range of human hearing, typically with a frequency of 20 MHz or greater. The magnetostrictive property is a material property, common to ferromagnetic materials, where the material is divided into uniform magnetic polarization domains, such that when a magnetic field is applied said domains shift and rotate causing the magnetostrictive material to change size at a high frequency, thus generating high frequency sound waves or ultrasound. In a magnetostrictive transducer, the magnetic field is provided by the magnetizing coil wrapped around the magnetostrictive material. The magnetic field of the magnetizing coil is produced by the input of electrical energy into the coil.
In some embodiments, the ultrasonic detector is a magnetostrictive detector comprising a magnetostrictive material, magnetizing coil, and magnetic enclosure, wherein the combination of the three elements completes a magnetic circuit. In the same manner as the magnetostrictive transducer, the magnetostrictive detector utilizes the magnetostrictive property of the magnetostrictive material to convert ultrasound to magnetic energy, which alters the magnetic field of the magnetizing coil, thus altering the electrical energy output of the magnetostrictive detector.
The magnetostrictive material is chosen from the group Cobalt, Terfenol-D, and Metglas 2605SC. In some embodiments, the magnetizing coil is manufactured from an electrically conductive material. Additionally, in some embodiments, the magnetostrictive transducer and the magnetostrictive detector utilize the same magnetostrictive material, magnetizing coil, and magnetic enclosure, consequently embodied as a magnetostrictive transceiver. Optionally, the magnetostrictive transducer and the magnetostrictive detector have separate magnetostrictive materials, magnetizing coils, and magnetic enclosures.
Optionally, the ultrasonic transducer is a capacitive actuator comprising two conductive plates on either side of a dielectric material, wherein electrical energy is passed from one conductive plate through the dielectric material to the second conductive plate. The passing of electrical energy across the conductive plates causes the conductive plates to acquire opposite charges, which further causes an attractive force to exist between the conductive plates. Electrical energy in the form of alternating current provides high frequency oscillation of the capacitive actuator, thus converting electrical energy into ultrasound.
In some embodiments, the ultrasonic detector is a capacitive actuator having the same properties as stated above. The process is reversed in the instance of the ultrasonic detector, such that ultrasound is received that affects the oscillation of the capacitive actuator, and the electrical energy passed between the two conductive plates through the dielectric material is altered as a result.
In some embodiments, the ultrasonic sensor is a microelectromechanical system (MEMS). A microelectromechanical system is characterized as a system comprising miniaturized mechanical and electro-mechanical elements that are fabricated using the techniques of microfabrication. A microelectromechanical system is further characterized as comprising miniaturized structures, referred to as microstructures; miniaturized sensors, referred to as microsensors; miniaturized actuators, referred to as microactuators; and microelectronics. Microsensors and microactuators are commonly referred to as microtransducers, which are miniaturized devices that convert energy from one medium to another, such as mechanical to electrical.
Accordingly, the ultrasonic transducer transmits ultrasound through the heel of the user into the user's bones and the ultrasound is reflected. The reflected ultrasound is received by the ultrasonic detector. The time between transmission and detection of ultrasound, essentially the speed of sound, is correlated to reference bone density data stored by the data processing unit.

A strain gage is comprised of an insulating flexible backing with a metallic foil pattern affixed and is attached to the connected surface in a proper place with an adhesive, such as cyanoacrylate. As a load is applied to the connected surface, the connected surface deforms causing the foil of the strain gage to deform that results in an electrical resistance change, which is typically measured using a Wheatstone bridge. The resistance change is converted into a strain value using a gage factor and the strain value is used to calculate the load on the connected surface, which provides the weight of the user providing the load.
An electronic analytical scale measures the load on the connected surface by countering the load applied using an electromagnet to generate a force. The measurement of the counter force applied by the electromagnet and the electromagnet itself are often comprised in an electromagnetic force restoration sensor.
A capacitive scale comprises a capacitive sensor that is constructed from two parallel conductive plates separated by an insulator such that, in the active portion of the sensor, the insulator allows for an air gap between the parallel plates. Forces acting perpendicular to the plane of the parallel plates in the active region deform one or both conductors. Accordingly, the parallel plates move closer together or farther apart due to deformation, thus, changing the capacitance of the sensor. The change in capacitance is scaled by a reference factor that provides the weight of the item causing the capacitance change.

Optionally, the body fat sensor 782 utilizes the method of near-infrared interactance comprising at least one infrared emitter and at least one photo detector. A beam of infrared light is transmitted into the user's body, often through the foot. The infrared light is reflected by non-fatty tissue and absorbed by fat tissue. The photo detector captures the reflected infrared light.

The impedance is correlated to body fat percentage of the user based on the user's gender, age, weight, and reference values. In general, fat is anhydrous and a poor conductor of electric current. Conversely, non-fatty tissue, water, and electrolytes are good conductors of electric current. Consequently, the percent body fat increases with increased impedance, thus providing a method of measuring percent body fat.
