Abstract: A system and method for providing prepaid wireless services. One embodiment includes a mobile unit configured to maintain an amount of time units for which the mobile unit is authorized to utilize wireless services. The amount of time units is preferably prepaid for by the customer. The mobile unit prevents utilization of wireless services upon the expiration of the amount of prepaid time units. Furthermore, it is preferred that a prepaid application server receive notification from the wireless service provider of the use of time units by the mobile unit. In this manner, the prepaid application server may monitor the availability of time units and prevent fraudulent use when the amount of prepaid time units expire.

Abstract: The present invention provides a mobile unit (e.g., phone) for wireless communication that includes an antenna for detecting wireless fidelity (Wi-Fi) signals from a local area network and logic for switching the unit's operation from conventional cellular transmissions to Wi-Fi transmissions (i.e. 802.11) upon detection of Wi-Fi signals. The handheld device can communicate with a Public Switched Telephone Network (PSTN) using Voice Over Internet Protocol VOIP. In one embodiment, the logic for performing the switch to Wi-Fi transmission is programmed into a subscriber identity module (SIM) card in the device and can perform the switch automatically or in response to manual input after prompting the user. Memory and code in the mobile unit measure and store the duration of both cellular and Wi-Fi transmissions by the mobile unit.

Abstract: The present invention provides new amino lipids and a convenient method for synthesizing these compounds. These (cationic) amino lipids have good properties as transfection agents. The method is an economic versatile two step synthesis allowing the preparation of various amino lipids thus leading to the assembly of a combinatorial library of transfection agents. Moreover, the present invention provides lipid particles (liposomes) containing said amino lipids and their use for delivering bioactive agents into cells. The invention encompasses also the use of lipid particles containing the cationic amino lipids as medicament.
