  • Patent number: 6788771
    Abstract: A method of operating a telecommunications device wherein the telecommunications device is used to detect an outgoing call from a calling party to a called number. The calling number is used to determine whether or not the calling party is a universal service user. If it is determined that the called number is among a class of numbers exempt from charges, the call is connected. A determination on the sufficiency of funds in a pre-paid account is made. If it is determined that there are insufficient funds in a pre-paid account to cover charges associated with the outgoing call, a message is generated and sent to the calling party or a third party requesting authorization to charge an additional fee for connecting the calling party with the called party and providing related information or application services. User input is received from the calling party, indicating the calling party's authorization of such charge. The connection between the calling party and the called party is made.

  • Patent number: 6772267
    Abstract: Split IEEE 1394 bridges utilize individual portals or bundles of portals to communicate over a non-full-featured IEEE 1394 network such as a local or wide area network in combination with IEEE 1394 multi-portal bridges. Multi-portal bridges may be formed through the connection of several split bridges each with one or more IEEE 1394 portals over a core net. The core net is invisible to the IEEE 1394 nodes with respect to traffic originating from an IEEE 1394 bus for a destination in an IEEE 1394 bus, and the network elements allow for increased network scalability in both terms of physical size and levels of hierarchy. Useful properties of a core net such as availability of high-performance switches or increased reach are incorporated into an IEEE 1394 network.

  • Patent number: 6756781
    Abstract: Described are improved transmissive magneto-optical sensors that may be used to determine the magnitude and phase of a magnetic field surrounding a conductor, and when in contact with the conductor, the surface temperature of the conductor. The magneto-optical sensor may be made to be symmetric around the direction of propagation of the internal light, enabling ease of manufacturing as well as automated assembly and calibration. The magneto-optical sensor may also be made to be symmetric about the plane determined by the Faraday rotator material, thus enabling reciprocating optical paths for increased vibration and birefringence immunity. The disclosed sensors preferably include cylindrically symmetrical components, thereby making the sensor readily mass-producible.

  • Patent number: 6534977
    Abstract: Described are the design of a rare earth iron garnet sensor element, optical methods of interrogating the sensor element, methods of coupling the optical sensor element to a waveguide, and an optical and electrical processing system for monitoring the polarization rotation of a linearly polarized wavefront undergoing external modulation due to magnetic field or electrical current fluctuation. The sensor element uses the Faraday effect, an intrinsic property of certain rare-earth iron garnet materials, to rotate the polarization state of light in the presence of a magnetic field. The sensor element may be coated with a thin-film mirror to effectively double the optical path length, providing twice the sensitivity for a given field strength or temperature change. A semiconductor sensor system using a rare earth iron garnet sensor element is described.
