  • Patent number: 6826593
    Abstract: A method of fulfilling a request for information content with a user-selectable version of a file containing that information content. Selection of a hyperlink to information content results in generation of a menu of versions of files containing that information content. The menu displays options for versions which are derivable therefrom by a computer program for converting files from one version to another version. Selection of an option for a materialized version results in transmission of the materialized version. Selection of an option for a version which is not materialized results in derivation of the user-selected version from either a materialized version or any other version from which the user-selected version may be derived. Apparatuses for carrying out the inventive method are also provided.

  • Publication number: 20040234192
    Abstract: A new filter architecture uses subband division and a reflector structure. A de-multiplexer/multiplexer combination creates N subband branches comprising dispersive elements, phase control elements, and/or delay elements. The new structure yields high spectral accuracy across the filter's overall free spectral range (FSR). In one embodiment of the inventive filter, the overall filter has a free spectral range (FSR) of F, and the first multiband filter (MBF) has a FSR of 1 F fmbf = F N .

  • Publication number: 20040235470
    Abstract: A method for controlling the flow of information between a UE and a Node B is provided. The UE transmits over a control channel to the Node B a signal requesting to transmit information to the Node B. The UE then receives over a shared channel from the Node B a signal identifying a time at which the UE is permitted to transmit information. Thereafter, the UE transmits at the identified time over a data channel to the Node B a signal containing the information.

  • Patent number: 6823191
    Abstract: Latency in receiving and detecting paging messages at a wireless terminal is reduced by employing a unique “super” paging time slot format. A paging super time slot includes a plurality of prescribed time slots. Each wireless terminal is associated with cyclically recurring super time slots. A super slot is associated with one or more wireless terminals. A base station always selects the first available time slot in a super time slot to transmit a paging message to a wireless terminal that is associated with the super time slot. Each wireless terminal monitors every time slot in the associated super time slot until either detecting reception of its associated paging message or detecting an empty time slot. In another embodiment of the invention, a unique partially overlapping super time slot format is employed in which a super time slot has at least one time slot common to its adjacent super time slots.

  • Patent number: 6823096
    Abstract: A switching apparatus provides 1×2 and 2×2 switching functions having significantly reduced crosstalk levels using an imaging arrangement of three arms combined with two star couplers. In another 1×2 switching element embodiment, the input star coupler is replaced with an optical signal splitter. Application of the 1×2 and 2×2 switching elements include the realization of a variety of dilated N×N broadband switches with negligible crosstalk over very wide wavelength stopband characterized by two or more equally spaced zeros. The very wide crosstalk stopband enables the N×N broadband switch to switch a broadband wavelength division multiplexed input signal to the desired output port with very low crosstalk at the other output ports.
