Abstract: A sensor device for sensing wetness in an absorbent article worn by a subject includes one or more sensing elements; and a coupling for communicating sensor signals between the one or more sensing elements and a receiver. A change in environmental parameter causes a change in electrical behavior of at least one of the sensing elements, which behavior can be analyzed to determine occurrence of a wetness event in the absorbent article. The changes in electrical behavior are communicated in the sensor signals to the receiver. The analysis may be by the receiver or a processor in communication with the receiver. Ideally, the sensing elements include capacitive elements and preferably, resonance circuits.

Abstract: A system for distribution of digital content includes at least one interactive terminal with a display, at least one battery, electronics for enabling digital image creation on the display, a communication module, and means for controlling an interactive touchless user interface in order to display selected content on the interactive terminal. In addition, a method for digital distribution of digital content with content pages c=1, 2, . . . , h to be displayed with at least one interactive terminal at at least one location j=1, 2, . . . , m, includes locating at least one i=1, 2, . . . , n interactive terminals at a defined location j=1, 2, . . . , m for displaying the digital content, providing means for interaction with a user via the touchless user interface, based on user input, and communicating with a server infrastructure to display selected content on the interactive terminal.
