Abstract: An electrically tunable coupler device is disposed on a substrate comprising a first and a second waveguide, for guiding optical signals. The coupler device comprises a heater element disposed adjacent the first waveguide for thermo-optically shifting the phase of the optical signal in the first waveguide in response to a control voltage applied to the heater element. The heater element is disposed in an interaction region of the optical signals, such that, within the interaction region, a temperature gradient across the first and the second waveguide is generated in dependence on the applied control voltage. A heat sink element can be disposed adjacent the second waveguide to absorb thermal energy from the heater element. This device can be fabricated at reduced cost and in increased packing density and is usable e.g. in directional couplers, Mach-Zehnder interferometers, optical ring resonators, IIR filters, or optical modulators.

Abstract: Disclosed is a method for linguistic pattern recognition of information. Initially, textual information is retrieved from a data source utilizing a network. The textual information is then segmented into a plurality of phrases, which are then scanned for patterns of interest. For each pattern of interest found a corresponding event structure is built. Event structures that provide information about essentially the same incident are then merged.

Abstract: A system, method, and article of manufacture are provided for navigating an electronic data source by means of spoken language. When a spoken input request is received from a user, it is interpreted. Additional input is solicited from the user in a modality different than the original request and used to refine the navigation query. The resulting interpretation of the request is thereupon used to automatically construct an operational navigation query to retrieve the desired information from one or more electronic network data sources.

Abstract: A system, method and computer program product are provided for providing a content exchange system. A request is received from a user utilizing a local system. A determination is made as to whether the user request can be fulfilled from information stored by the local system. The request is fulfilled from a local data source if the request can be fulfilled locally. If the request cannot be fulfilled locally, the request is fulfilled at a network site. A content directory connected to the network site is examined for selecting one or more network data sites having content potentially satisfying the request. The request is sent to the data site(s). Content pertaining to the request is received from the data site(s) and sent to the user.

Abstract: A system, method and computer program product are provided for giving feedback in an educational environment using networked devices. Initially, an image stimulus is displayed to a plurality of individual group members regarding material being presented by a group leader utilizing a plurality of networked devices operated by the group members. Thereafter, feedback is received from the individual group members in response to the image stimulus utilizing the networked devices. The feedback is then aggregated after which the aggregated feedback is transmitted to the networked device operated by the group leader. Such aggregated feedback reflects the feedback received from each of the individual group members for allowing the group leader to view the aggregated feedback.

Abstract: An apparatus and concomitant method of reducing the number of synchronization pulses transmitted to the alarm units for increasing the reliability of the overall alarm system is disclosed. The synchronization signal is implemented as a reference or reset signal from which the alarm units derive a reference time to begin activation of the alarm units. Thus, when an alarm unit receives a reference synchronization pulse, the alarm unit applies the reference synchronization pulse as a reference point in time to trigger a series of flashes or audio tones.
