Abstract

Hair grooming device, system and method for measuring interaction with hair of a person during a hair grooming event, including a processor readable storage medium, storing executable instructions and a processor in communication with the processor readable storage medium.

First claim

What is claimed is:

1. A method for measuring interaction of a hair grooming device with hair of a person during a hair grooming event, the method comprising:
(a) collecting data from at least one sensor integrated with the hair grooming device during the hair grooming event, wherein the at least one sensor measures interaction of the hair grooming device with the hair and collects a respective first data value for each of a series of discrete time periods;
(b) concurrent with collecting the data, determining at least one value indicative of a proximity of the hair grooming device to the hair of the person using a proximity sensor integrated with the hair grooming device, wherein determining the at least one value indicative of a proximity of the hair grooming device to the hair of the person comprises determining a respective second data value corresponding to each of the discrete time periods;
(c) based on the at least one value indicative of the proximity of the hair grooming device to the hair, filtering the data collected from the at least one sensor, wherein filtering the data collected from the at least one sensor comprises:
i) determining a respective weighting value for each of the discrete time periods based on the respective second data value corresponding to each discrete time period, and
ii) calculating a respective adjusted data value for each discrete time period based on the respective first data value and the respective weighting value corresponding to each discrete time period, wherein the filtered data comprises the respective adjusted values; and

(d) storing the filtered data.

2. The method of claim 1 , wherein the hair grooming device comprises a brush, a comb or other device including a structural feature configured to contact the hair of the person when in use.

3. The method of claim 2 , wherein the at least one value indicative of the proximity of the hair grooming device to the hair of the person is indicative of the proximity of the structural feature to the hair of the person.

4. The method of claim 1 , wherein filtering the data comprises:
determining a weighting amount based on the at least one value indicative of the proximity of the hair grooming device to the hair; and
adjusting the collected data based on the weighting amount.

5. The method of claim 1 , wherein the proximity sensor comprises a light-dependent resistor.

6. The method of claim 1 , wherein the at least one sensor comprises one or more of a pressure sensor, a load cell, an accelerometer, or a gyroscope.

7. The method of claim 1 , wherein storing the filtered data comprises storing the filtered data in memory circuitry integrated with the hair grooming device or transmitting the filtered data to an apparatus external to the hair grooming device, the apparatus comprising memory circuitry configured to store the filtered data.

8. The method of claim 1 , comprising:
transmitting the collected data to an apparatus external to the hair grooming device;
transmitting, to the apparatus, the at least one value indicative of the proximity of the hair grooming device to the hair of the person; and
wherein the filtering of the data collected from the at least one sensor comprises filtering, by the apparatus, the transmitted collected data based on the transmitted at least one value indicative of the proximity of the hair grooming device to the hair of the person.

9. The method of claim 1 , wherein filtering the collected data comprises discarding the collected data when the at least one value indicative of the proximity of the hair grooming device to the hair of the person indicates that the hair grooming device is not proximate to the hair of the person.

10. The method of claim 1 , wherein the step of collecting data includes collecting first data from the at least one sensor integrated with the device during a first hair grooming event;
the step of determining at least one value indicative of a proximity of the hair grooming device to the hair of the person using a proximity sensor integrated with the hair grooming device determines at least one first value indicative of a proximity of the device to the hair of the person;
and based on the at least one first value indicative of the proximity, the first data collected from the at least one sensor is filtered; and the method further comprises:
collecting second data from the at least one sensor integrated with the device during a second hair grooming event;
concurrent with collecting the second data, determining at least one second value indicative of the proximity of the device to the hair of the person using the proximity sensor integrated with the device;
based on the at least one second value indicative of the proximity, filtering the second data collected from the at least one sensor; and
comparing the filtered first data to the filtered second data.

11. A system for measuring interaction of a hair grooming device with hair of a person during a hair grooming event, the system comprising:
the hair grooming device;
a sensor integrated with the hair grooming device, wherein the sensor measures interaction of the hair grooming device with the hair;
a processor in communication with a processor readable storage medium with executable instructions stored thereon, wherein the processor, when executing the executable instructions:
(a) collects data from the at least one sensor by collecting a respective first data value for each of a series of discrete time periods, and
(b) concurrent with collecting the data, determines, using a proximity sensor integrated with the hair grooming device, at least one value indicative of a proximity of the hair grooming device to the hair of the person, wherein determining the at least one value indicative of a proximity of the hair grooming device to the hair of the person comprises determining a respective second data value corresponding to each of the discrete time periods;

a filter applied to the data collected from the at least one sensor, wherein the filter is based on the at least one value indicative of the proximity of the hair grooming device to the hair, and wherein applying the filter to the data collected from the at least one sensor comprises:
(a) determining a respective weighting value for each of the discrete time periods based on the respective second data value corresponding to each discrete time period; and
(b) calculating a respective adjusted data value for each discrete time period based on the respective first data value and the respective weighting value corresponding to each discrete time period, wherein the filtered data comprises the respective adjusted values; and

a storage device in communication with the filter and configured to store the filtered data.

12. The system of claim 11 , wherein the hair grooming device comprises a brush, comb or other device including a structural feature configured to contact the hair of the person when in use.

13. The system of claim 11 , wherein applying the filter to the data collected from the at least one sensor comprises:
determining a weighting amount based on the at least one value indicative of the proximity of the hair grooming device to the hair; and
adjusting the collected data based on the weighting amount.

14. The system of claim 11 , wherein the proximity sensor comprises a light-dependent resistor.

15. The system of claim 11 , wherein the at least one sensor comprises one or more of a pressure sensor, a load cell, an accelerometer, or a gyroscope.

16. The system of claim 11 , wherein the processor when executing the executabl
