Abstract

A sensor device includes a signal transmitting component configured to transmit a signal into a container engaged by the sensor device, wherein a frequency of the signal is selected to allow the signal to at least in part pass through a content fouling at least a portion of the signal transmitting component. The sensor device includes a processor configured to process a received reflected version of the transmitted signal to determine an identifier associated with an amount of content in the container engaged by the sensor device. The sensor device includes a wireless transmitter configured to transmit the identifier associated with the amount of content in the container.

Claims (37)

1. A sensor device, comprising:

a signal transmitting component configured to transmit signals into a container engaged by the sensor device, wherein each signals' parameters are selected to allow the signals to at least in part pass through a content fouling at least a portion of the signal transmitting component;

a processor configured to process each received reflected version of each of the transmitted signals to determine an identifier associated with an amount of content in the container engaged by the sensor device;

a lens configured to shape the transmitted signals and wick away the content fouling to reduce fouling over a time; and

a wireless transmitter configured to transmit the identifier associated with the amount of content in the container

wherein the processor compares a first received reflected version of a first transmitted signal with a second reflected version of a second transmitted signal, which second transmitted signal was transmitted after the first transmitted signal, to determine if measured amount of content in the container is reliable and determine adjustments that need to be made to parameters of future signals transmitted into the container.

2. The device of claim 1 , wherein the signal transmitting component is a transceiver configured to receive the reflected version of each of the transmitted signals.

3. The device of claim 1 , wherein the signal transmitting component is a transmitter and the device further includes a receiver configured to receive the reflected version of each of the transmitted signals.

4. The device of claim 1 , wherein the frequency of the transmitted signals is equal to or above 80 kHz.

5. The device of claim 1 , further comprising a measuring chamber configured to indicate an amount of content in the measuring chamber.

6. The device of claim 5 , wherein an indication of the amount of content in the measuring chamber includes a physical marker on a wall of the measuring chamber.

7. The device of claim 5 , further comprising an electronic sensor configured to detect the amount of content in the measuring chamber.

8. The device of claim 7 , wherein the electronic sensor includes a capacitive sensor.

9. The device of claim 7 , wherein the electronic sensor includes a force, pressure, resistive or weight sensor.

10. The device of claim 5 , wherein the identifier associated with the amount of content in the container is determined based at least in part on the amount of content in the measuring chamber.

11. The device of claim 5 , further comprising one or more of the following: a light indicator configured to indicate a light associated with the amount of content in the measuring chamber, a sound generator configured to indicate a sound associated with the amount of content in the measuring chamber, or a vibration generator configured to indicate a vibration associated with the amount of content in the measuring chamber.

12. The device of claim 1 , wherein the transmitted identifier associated with the amount of content in the container is based on a determination that the amount of content in the container is below a threshold.

13. The device of claim 1 , wherein the wireless transmitter is a Wi-Fi transmitter or a personal area network transmitter.

14. The device of claim 1 , wherein the identifier associated with the amount of content in the container is used to track an inventory of the content in the container.

15. The device of claim 1 , wherein the identifier associated with the amount of content in the container is used to determine that the sensor device has been coupled to a new container.

16. The device of claim 1 , wherein the identifier associated with the amount of content in the container triggers an automatic reordering of a product of the container.

17. The device of claim 1 , wherein the container is a laundry detergent container.

18. The device of claim 1 , further comprising one or more of the following: an actuated shutter, an actuated wiper, an actuated hatch, a blower, or a vacuum pump.

19. A system, comprising:

a processor; and

a communication receiver configured to receive an identifier associated with an amount of content in a container, wherein the identifier is provided by a sensor device that includes:

a signal transmitting component configured to transmit signals into the container, wherein each signals' parameters are selected to allow the signals to at least in part pass through a content fouling at least a portion of the signal transmitting component;

a processor configured to process each received reflected version of each of the transmitted signals to determine the identifier associated with the amount of content in the container engaged by the sensor device;

a lens configured to shape the transmitted signals and wick away the content fouling to reduce fouling over a time; and

a wireless transmitter configured to transmit the identifier associated with the amount of content in the container,

wherein the processor compares a first received reflected version of a first transmitted signal with a second reflected version of a second transmitted signal, which second transmitted signal was transmitted after the first transmitted signal, to determine if measured amount of content in the container is reliable and determine adjustments that need to be made to at least one parameter selected from the parameters of future signals transmitted into the container.

20. A sensor device, comprising:

a measuring chamber configured to indicate an amount of content in the measuring chamber in a first orientation of the sensor device;

a signal transmitting component configured to transmit signals in a second orientation of the sensor device different from the first orientation of the sensor device;

a processor configured to process each received reflected version of the transmitted signals to determine an identifier associated with an amount of content in a container engaged by the sensor device, wherein the processor compares a first received reflected version of a first transmitted signal with a second reflected version of a second transmitted signal, which second transmitted signal was transmitted after the first transmitted signal, to determine if measured amount of content in the container is reliable and determine adjustments that need to be made to at least one parameter selected from the parameters of future signals transmitted into the container; and

a wireless transmitter configured to transmit the identifier associated with the amount of content in the container if the measured amount is reliable.

21. The device of claim 20 , further comprising a lens surrounding at least a portion of the signal transmitting component for shaping transmitted signals and wicking away the content over a time.
