Abstract: The present application relates to an electronic wetness-sensing absorbent article and related methods. The electronic wetness-sensing absorbent article includes a flexible waterproof thin film; at least two mutually separated and insulated flexible electrodes disposed on one surface of the flexible waterproof thin film; a water-permeable braided fabric layer; and an absorbent layer disposed on the other surface of the flexible waterproof thin film, located between the flexible waterproof thin film and the water-permeable braided fabric layer, and adapted to absorb a liquid entering from the water-permeable braided fabric layer. The flexible waterproof thin film, the flexible electrodes, and the liquid contained in the absorbent layer form a non-polar variable electrolytic capacitor. The wetness state of the electronic wetness-sensing absorbent article is obtained by detecting the capacitance value of the variable electrolytic capacitor and change thereof.

Abstract: A method and system for conducting interactive classroom learning that can utilize a plurality of electronic audio and video equipment, mobile computing devices, and processing servers, interconnected via a first network infrastructure in a classroom or presentation hall to deliver seamlessly interactive multimedia contents to each of one or more participants in classroom or presentation hall; wherein the participants comprises one or more lecturers or presenters, and one or more students or audiences.

Abstract: A blood glucose calibration system has a noninvasive sensor that attaches to a person's tissue site so as to generate multi-stream physiological data responsive to that person's blood constituents. Composite parameters, each in the form of a mathematical combination of invasive blood panel parameters, are derived from a general population and are responsive to the multi-stream physiological data. A population-based, blood glucose estimate for that person is derived from a weighted and scaled combination of these composite parameters. An individualized blood glucose estimate is then derived from the population-based blood glucose estimate and intermittent invasive test strip measurements of that particular individual.

Abstract: A method for execution by at least one server within a domain of a service provider. The method comprises receiving a first request from a communication device registered with the service provider. A response including a token is sent to the communication device. Then a second request is received, this one from an application server over a communication channel at least partly not within the domain of the service provider. The second request contains the token, which causes the at least one server to send a response to the application server, which response includes information about the communication device obtained based on the token. Use of the token facilitates customer access to data services and applications, while making the token anonymous safeguards the privacy of customer data.
