VIEW). LabVIEW can perform not only data acquisition and logging but also processing (e.g., digital filtering, identification-classification, compression, etc.) and communication. If the PDA has also "SmartPhone" capabilities, it can also transfer the data via mobile communications (e.g., toward a central server). If not, a cheap alternative (that was integrated by the authors) is the connection to the owner's mobile phone that can be controlled, for instance, via AT commands (for dial-up, GPRS and/or SMS transmissions). Local data-logging can be used for data acquisition and detailed diagnosis (human and/or automated) while mobile tele-transmission can be used mainly for updates and alarms. As demonstrated, tele-monitoring is the basis of remote management technol- ogy and can be enhanced with two-way communications that allow better person- alization of support. Personal means of communication, like mobile phones and SmartPhones or PDA-based "communicators" are more and more involved in dif- ferent ways of monitoring (direct physiologic feedback), logging, tracing but also messaging (including alarms when threshold values are reached) and notifications of decisions-all these in a way that should be tailored to the patient's capability and needs. For remote monitoring, many portable devices were developed for acquisition, logging, processing, and transmission of acquired data. Digital signal processing (DSP) enable complex analysis and allow real-time decisions. The authors developed different tele-monitoring systems in the last years. A "twin-microcontroller" solution had one microcontroller allocated to the control of data acquisition and processing, and another one to the management of communica- tions (interfacing and control of a GSM modem). Such dual-processor solutions are Tele-Measurement Services for m-Learning common even to SmartPhones (only recently DSP and general purpose processing were brought to a common core). 12.3.1.2.1 System's Architecture The most recent system implemented by the authors, wi
