Abstract: A system and method for monitoring pH of an intraoral device involves receiving the oral pH data from at least one pH sensor embedded within the intraoral device. The oral pH data is then correlated with one or more user related data to classify the oral pH data into one or more pre-defined categories indicative of a health condition. Further, the machine learning module generates feedback and/or recommendations for the user based on the classification of the oral pH data into one or more pre-defined categories. The oral pH data and/or feedback and/or recommendations are then communicated to the user and/or external device.

Abstract: A masseter muscle monitoring apparatus comprises a sensor unit comprising an optical sensor connected to a transmitter, both of which are mounted on a support having means for attachment to molars on a jaw within a buccal cavity of a patient. The support is positioned within the buccal cavity adjacent a masseter muscle in the check of the patient, with the sensor unit facing the masseter muscle so the sensor unit can monitor the activity of the masseter muscle without interfering with the masseter muscle. Monitoring information collected by the sensor unit on the support is transmitted wirelessly by the associated transmitter on the support to a remote receiver unit such as a mobile phone. Masseter muscle activity is shown in a graphical indication on a screen of the remote receiver unit to show events such as a grind event or a clench event.

Abstract: An intraoral monitoring device includes a flexible substrate, a plurality of sensors, a rechargeable battery, a device module and a communication module. The plurality of sensors senses a plurality of health parameters from an associated user, in real time, to generate a plurality of sensed signals. The device module includes a memory, a controller and a segregation module. The memory stores various health parameters and their respective ranges, various health reports of the user, and basic details of all users. A controller is configured to generate sensed data and the segregation module is configured to segregate the data corresponding to the plurality of health parameters associated with the users. A communication module is configured to enable data communication to and from the intraoral device.

Abstract: An intraoral monitoring device includes a plurality of sensors integrated on a flexible substrate. The plurality of sensors includes first and second photoplethysmography (PPG) sensors. The first PPG sensor is coupled along an anterior portion of the flexible substrate and adapted to be located intraorally along a first anatomical location defined along a mid-line of a maxilla, facing the labial mucosa, directly at a septal branch of a superior labial artery in a front lip to consistently provide a plurality of first PPG signal, relating to a plurality of cardiorespiratory parameters. Further, the second PPG sensor is coupled to a rear portion of the flexible substrate, adapted to be located intraorally along a second anatomical location defined along the interior part of an oral cavity facing outward toward the labial mucosa to consistently provide a plurality of second PPG signals, relating to a plurality of muscular parameters.

Abstract: Articles such as compact discs are traded among a plurality of members who are registered in a common community. Each member has an account including a trading credit balance and a mailing address. A user interface is provided that allows a member to enter articles that the member owns and is willing to trade and articles that the member wants to own. The user interface also receives article trading instruction messages. An administration computer hosts the plurality of members and facilitates article trades among the members. The administration computer identifies matches between owned and wanted articles. For each identified match, an article trading instruction message is sent to the article owner requesting that the article owner mail the owned article to the mailing address of the member who wants to own the article.
