Abstract: A Broadband Intelligent Network employs an ATM fast-packet switch to route signaling cells from a calling party to a switch port directly connected to a Service Control Point (SCP) (61). The signaling cells carry a service request that requires the support of a network resource, and, in the specific case described herein, the support of the Line Information Data Base (LIDB) (150) to facilitate the establishment of a switched virtual connection to a called party (54). The SCP (61) acts on the information in the signaling cells and selects the required resource, i.e., the LIDB (150), and then sends a query cell(s) to the LIDB (150) through a permanent virtual connection in the ATM switch (51). The LIDB (150), in turn, acts on the information in the query cell(s) to assemble a response cell(s) with the requested information. The response cell(s) is sent to the SCP (61) through the permanent virtual connection in the ATM switch (51), thereby enabling the SCP to complete call processing, establish the requested connection, and generate a billing record (65).

Abstract: Our video-conferencing system (10) comprises stations (20, 30) which are remotely located from one another and interconnected by a transmission system (12). Each station includes a camera (23, 33), a projector (21, 31), and a screen (22, 32), which is simultaneously translucent with respect to the projector and transparent with respect to the camera. The projector as well as the camera are placed behind and in line with the screen, thus allowing greater viewing reciprocity and eye-contact and projecting a stronger feeling of reality to the video-conferencing parties. Our screen includes segments which discriminates between projected light and light to be captured by the camera based upon polarization or angle.

Abstract: Lithium intercalation compounds suitable for use in high capacity secondary battery electrodes (44) are prepared by reacting together at a temperature in the range of about 800 to 900 DEG C lithium and manganese compounds in a stoichiometric ratio resulting in an LixMn2O4 compound wherein x is within the range of about 1.00 to 1.10. The resulting compound is annealed at a temperature in excess of about 800 DEG C and cooled to at least about 500 DEG C at a rate of less than about 10 DEG C per hour before being finally cooled to ambient working temperature. Intercalation electrodes (44) comprising these lithiated compounds are used in secondary batteries to yield stable, extended capacities in excess of 110 AHr/Kg. Lithium metal foil (42) used as the negative electrode, an electrolyte separator (43), a positive electrode (44) and electrically conductive contacts (46 and 48) form a complete cell.

Abstract: A cryptographic certificate attesting to the authenticity of the original document elements will lose its validity when the cryptographic function underlying the certifying scheme is compromised. The present invention extends the reliability of such a certificate by subjecting the combination of the original certificate and the digital representation of the document to a scheme based on a less vulnerable function using the steps of: obtaining the original document (11); applying the function to the document to create the original certificate (13); combining the original document and the certificate (15); and, applying another function to the combination to create an extended certificate (17).

Abstract: A method of an apparatus for extracting dielectric constants from ellipsometric data taken during the growth of a semiconductor thin film (10) and using the extracted dielectric constants to control the composition of the growing film by adjusting the growth conditions. An expression is used for the derivative of the pseudo-dielectric function with respect to the thickness of the thin film within a three-phase model, and the expression is exact to first order in thickness of the film. The expression is quadratic with respect to the dielectric function for a homogeneous thin film and additionally depends on the dielectric function of homogeneous substrate (12) underlying the thin film. Values of the measured pseudo-dielectric function are substituted for the dielectric function of the substrate, and the expression is then solved for the dielectric function of the thin film.

Abstract: A method of forming crystalline metal oxide thin films on silicon and the resultant structure. A crystalline buffer layer (10) of yttria-stabilized zirconia is deposited on a silicon substate (12). A thin template layer (14) of an anisotropic perovskite such as bismuth titanate or yttria barium copper oxide is deposited on the buffer layer under conditions favoring (c)-axis oriented growth. A nominally cubic metal-oxide layer (16) is deposited on the template layer which facilitates its singly crystalline growth. The metal oxide, often a nominally cubic perovskite, may be a conductive electrode, a ferroelectric, a non-hysteretic dielectric, a piezoelectric, or other class of material.

Abstract: Methodology, and associated circuitry, for encoding (e.g., 200) and decoding (e.g., 900) an incoming data stream (201) utilize a coordinated code constellation (e.g., Fig. 3) that effects robust signal detection in the presence of channel interference. The encoder (220) partitions the incoming data stream into contiguous data segments in proportion to the number of levels for a given coordinated code. Each data segment is mapped with reference to the coordinated code to signal levels suitable for transmission over a plurality of channels (e.g., 222, 223). The decoder measures (e.g., 900) the received signals on the channels and estimates noise statistics for the channels. A metric relationship engendered by the coordinated code is evaluated with reference to the received signals, estimates to the received signals, and the noise statistics. An output data stream is then generated based on the evaluation of the metric.

Abstract: A methodology and concomitant circuitry (1000) for smoothing delay sensitive traffic utilizes short term traffic forecasts and guarantees meeting a prespecified delay constraint. The pattern of incoming traffic is used to forecast estimates of future incoming data from the present and past incoming data. Corresponding to the estimate is a data rate for propagating stored data to produce a smoothed outgoing data rate, and the interval of time over which such a rate is used so as to satisfy the delay constraint. The estimation procedure is then re-invoked at the end to the time interval, which takes into account data arriving during the time interval, so as to determine the next succeeding data rate and a new time interval for propagating stored data.
