Abstract: A wireless payment system allows high speed operation without user intervention with the convenience that cellular phones provide. The system being described uses a wireless stored value module attached to an ordinary cellular phone or embedded in the cellphone's Subscriber Identity Module (SIM) card. A Reader is installed in points of transaction that communicates with the module and deducts the balance stored in the module for effecting the payment. The transaction is sent by the Reader to a central database to update a copy of the module's balance and perform settlement functions at the end of the day. After every transaction, a SMS or text confirmation is received by the cellphone user which indicates the amount paid and remaining balance in the module. Re-loading of values in the module can be accomplished solely by sending text messages using a cellular phone from anywhere, any time.

Abstract: A flight recorder designed for small aircraft captures various onboard flight data in real-time and stores it in non-volatile memory. Recorded data includes aircraft's instantaneous position, altitude, attitude, engine RPM, G forces, flap position, cockpit voice and others. These data are obtained from various sensors which are integrated into the recorder. At the end of a flight the recorded data is downloaded into a computer using a wireless communications data transceiver also integrated into the recorder. It does not require removal or attaching any equipment to be able to download data. In addition to accident investigation, applications include training, preventive maintenance and asset monitoring.

These data are obtained from various sensors which are integrated into the recorder. At the end of a flight the recorded data is downloaded into a computer using a wireless communications data transceiver also integrated into the recorder. It is an inexpensive system that does not require interfacing to any of the aircraft's instruments. It does not require removal or attaching any equipment to be able to download data. In addition to accident investigation, applications include training, preventive maintenance and asset monitoring.
