Bruxism Detection System With Chin-Mounted Accelerometer Sensor
First Claim
1. A bruxism detection system, comprising:
- a. a detection module that includes a single accelerometer and a local processor that includes a recording and processing system, the recording and processing system including (i) a sensor interface, (ii) a processor with memory, (iii) non-volatile storage, (iv) a communication interface, and (v) a power source; and
b. an adjoint processor in communication with the recording and processing system of the detection module,wherein at least one of the local processor and the adjoint processor is programmed to detect bruxism from multi-axis motion data collected by the single accelerometer by calculating motion signature parameters that include one or more of mean, variance and frequency components of motion, and comparing the calculated motion signature parameters with preconfigured motion signature parameters that correspond to bruxism.

Abstract
A bruxism detection system is provided that includes a chin-mounted acceleration sensor for detection of teeth grinding and teeth tapping. The system generally includes an acceleration sensor that is adapted to be removably and externally mounted with respect to an individual'"'"'s chin, a bruxism recording and processing system operable on a local processor, and bruxism analysis software that is operable on the local processor or an adjoint processor (or a combination thereof). The system is designed to be used in any convenient location, including an individual'"'"'s home, and is generally reusable by multiple people, thus reducing the cost of bruxism diagnosis and bringing a reliable and effective diagnosis tool to the general public.

13. A method for detecting bruxism, comprising:
-
a. detachably mounting a detection module with respect to a chin of an individual, the detection module including a single accelerometer and a local processor that includes a recording and processing system, wherein the recording and processing system includes (i) a sensor interface, (ii) a processor with memory, (iii) non-volatile storage, (iv) a communication interface, and (v) a power source; b. collecting multi-axis motion data with the accelerometer included in the detection module; c. pre-filtering the multi-axis motion data to exclude data that is not relevant to bruxism detection; and d. transmitting the filtered motion data to an adjoint processor; and e. processing the filtered motion data at the local processor, the adjoint processor or a combination of the local processor and the adjoint processor to detect bruxism, the processing including calculation of motion signature parameters that include one or more of mean, variance and frequency components of motion, and comparison of the calculated motion signature parameters with preconfigured motion signature parameters that correspond to bruxism.
