Abstract

The present invention relates to a smart diaper changing pad for weighing an infant or toddler and communicating the recorded information wirelessly to a mobile computer. The diaper changing pad incorporates force or mass sensors for measuring weight. The changing and cleaning pad and a separate computing system are wirelessly connected, either directly or through a network capable of both internal and external communication. An application installed on the mobile computer can track measurements from the diaper changing pad and keep a historical record, which may provide peace of mind and insight into a baby'"'"'s health and development. The key components of the product are a soft pad, a rigid platform, one or more sensors capable of measuring force or weight, a power source, a memory, a processor, and a wireless communication method. The invention can optionally include a display and a number of user inputs such as buttons or switches.

Claims

1. A smart scale system comprising:

a scale comprising;

an ovular weighing platform comprising two elevated sidewalls connected to and curving up from opposite sides of a cushioned surface, the weighing platform comprising a rigid lower element beneath a foam upper element with a waterproof or water resistant outer surface;

four slip-resistant feet extending from the bottom side of the rigid lower element, each foot including a sensor configured to measure force or mass;

a processor configured to convert the readings from the four sensors to determine a weight reading;

a memory connected to the processor and configured to store the weight readings;

a Bluetooth or Bluetooth Low Energy communication module configured to wirelessly transmit the weight readings to an electronic mobile device; and

a power source; and

an application running on the electronic mobile device that, when executed, causes one or more processors in the external computing device to;

wirelessly receive the weight reading from the wireless communication module of the smart scale system;

record the weight reading in a weight log associating the weight reading with a user profile;

display the weight reading on a screen of the electronic mobile device;

chart the weight readings in the weight log for the user profile over time; and

transmit the weight reading to a cloud data storage.

2. The smart scale system of claim 1 wherein the smart scale system includes a nursing function that comprises:

determining a first weight reading before nursing an infant;

determining a second weight reading after nursing the infant;

calculating the difference to determine the feed weight of liquid consumed by the infant; and

displaying the feed weight on the screen of the electronic mobile device.

3. The smart scale system of claim 1 wherein the smart scale system includes a changing function that comprises:

determining a first weight reading before changing an infant'"'"'s diaper;

determining a second weight reading after changing the infant'"'"'s diaper;

calculating the difference to determine the waste weight in the diaper; and

displaying the waste weight on the screen of the electronic mobile device.

4. A smart scale system comprising:

a scale comprising;

a weighing platform comprising two elevated sidewalls connected to opposite sides of a cushioned surface, the weighing platform comprising a rigid lower element beneath a cushioned upper element;

a plurality of slip-resistant feet extending from the bottom side of the rigid lower element, each foot including a sensor configured to measure force or mass;

a processor configured to convert the readings from the plurality of sensors to determine a weight reading;

a memory connected to the processor and configured to store the weight readings;

a wireless communication module configured to wirelessly transmit the weight readings to an electronic mobile device; and

a power source; and

an application running on the electronic mobile device that, when executed, causes one or more processors in the external computing device to;

wirelessly receive the weight reading from the wireless communication module of the smart scale system;

record the weight reading in a weight log associating the weight reading with a user profile; and

display the weight reading on a screen of the electronic mobile device.

5. The smart scale system of claim 4 wherein the wireless communication module comprises a Bluetooth or Bluetooth Low Energy communication module.

6. The smart scale system of claim 5 wherein the weighing platform is ovular and the two elevated sidewalls curve up from the cushioned surface.

7. The smart scale system of claim 6 wherein the cushioned upper element comprises foam and a waterproof or water resistant outer surface.

8. The smart scale system of claim 6 further comprising a safety restraint to secure a load atop the weighing platform.

9. The smart scale system of claim 5 wherein the application further causes the one or more processors to chart the weight readings in the weight log for the user profile over time.

10. The smart scale system of claim 5 wherein the application further causes the one or more processors to transmit the weight reading to a cloud data storage.

11. The smart scale system of claim 5 wherein the application further causes the one or more processors to trigger an alert message to a second electronic mobile device.

12. The smart scale system of claim 5 wherein the smart scale system includes a nursing function that comprises:

determining a first weight reading before nursing an infant;

determining a second weight reading after nursing the infant;

calculating the difference to determine the feed weight of liquid consumed by the infant; and

displaying the feed weight on the screen of the electronic mobile device.

13. The smart scale system of claim 12 wherein the application further causes the one or more processors to calculate the liquid volume consumed by the infant and to display the liquid volume consumed on the screen of the electronic mobile device.

14. The smart scale system of claim 12 wherein the application further causes the one or more processors to trigger an alert message including the feed weight to a second electronic mobile device.

15. The smart scale system of claim 5 wherein the smart scale system includes a changing function that comprises:

determining a first weight reading before changing an infant'"'"'s diaper;

determining a second weight reading after changing the infant'"'"'s diaper;

calculating the difference to determine the waste weight in the diaper; and

displaying the waste weight on the screen of the electronic mobile device.

16. The smart scale system of claim 14 wherein the application further causes the one or more processors to enable a user to note if the diaper associated with the waste weight included urine, feces, or both.

17. The smart scale system of claim 4, wherein the smart scale system further comprises a tare function to zero out the weight on the scale.

18. The smart scale system of claim 4, wherein the application further comprises displaying a historical graph showing the weight readings over time.

19. The smart scale system of claim 4, wherein the application further comprises associating a length log with the user profile and recording length entries over time in the length log.

20. The smart scale system of claim 4, wherein the smart scale system further comprises enabling a user to associate a photo of the baby with the user profile.
