Abstract: A medical balloon includes at least one internal wall dividing the balloon into a plurality of separate chambers which may be separately inflatable and deflatable. The at least one internal wall is impregnated with heat conductive particles. The heat conductive particles enable heat produced during the balloon blowing process to pass through the polymer material of the balloon and specifically into the internal wall or walls, enabling these to soften and stretch during the process. This improves the integrity of the balloon and also balloon flexibility. The radiopaque particles embedded in the internal wall or walls of the balloon can also, in preferred embodiments, be of radiopaque material, providing the balloon with imaging visibility during deployment thereof in a patient.

Abstract: An adaptor is shaped for allowing use of a micro SIM card in a mini SIM card implemented device. An adaptor body is shaped like a micro SIM card and may include a cutout region for receiving a micro SIM card therein.

Abstract: A data networking system includes a physical interface module of a first type, configured to transfer data traffic that meets a first requirement, a physical interface module of a second type, configured to transfer data traffic that meets a second requirement, the second requirement being different from the first requirement, a packet switch, and a hybrid switching module configured to transfer data between the first physical interface module and the packet switch, and to transfer data between the second physical interface module and the packet switch.

Abstract: A virtual private network service provider is used to transfer data over a data network to a final destination, with third-party billing. The method comprises the steps of: prompting the user at a data terminal to select a destination, password, and call type; sending a set-up message to the data network; selecting a virtual private network provider through the data network; the virtual private network provider giving an encryption key to the user, and then prompting the user for a password and a user identification; encrypting the password, and sending the user identification and the encrypted password to the virtual private network provider; the virtual private network provider decrypting the encrypted password, and verifying the password; the virtual private network provider providing an authorization code; and the data terminal transferring the data through the data network to the final destination, using the authorization code.

Abstract: A system comprises a first asynchronous transfer mode switch, a second asynchronous transfer mode switch, and a system control module. The first asynchronous transfer mode switch and the second asynchronous transfer mode switch are interconnected with one another via a physical interface. The first asynchronous transfer mode switch is in communication with the with the second asynchronous transfer mode switch via a virtual connection on the physical interface. The virtual connection has a corresponding bandwidth. The system control module is in communication with the first asynchronous transfer mode switch. The system control module is in communication with the second asynchronous transfer mode switch via the first asynchronous transfer mode switch and the physical interface. The system control module dynamically controls the corresponding bandwidth of the virtual connection over time.
