Abstract: A system, method and computer program for managing resources within an integrated development environment for multiple users. The resources include both content resources and people resources. The method comprises: managing a plurality of nodes representing resources, said nodes including content nodes and person nodes, wherein the node contains a resource reference for referencing the resource; managing one or more links representing one or more relationships between the resources, said links including links between content nodes, between person nodes and between content and person nodes, each link comprising node references to identify the nodes in the relationships and an importance value to identify the importance of the relationship; providing an interface for selecting one of the plurality of content nodes or person nodes; adapting, in response to the user selected node, one or more importance values of certain links.

Abstract: The present invention provides a touch sensitive input device that uses vibrations due to touch impacts and/or frictional movement of a touch implement across a surface to determine information related to the touch, such as touch position. The present invention also provides for detecting lift-off events in such vibration sensing input devices. Lift-off detection can be accomplished by monitoring for a signal that indicates a sustained touch on the touch plate, and correlating a change in such a signal with a lift-off event. Signals indicating a sustained touch can include low frequency rumbles coupled into the touch plate via the touch implement, touch plate bending under the force of a sustained touch, and touch plate displacement under the force of a sustained touch.

Abstract: A touch sensitive apparatus includes a touch plate and a number of sensors coupled to the touch plate. Each of the sensors is configured to sense bending waves in the touch plate and, in response to a touch to the touch plate, generate sensor signals. A controller is coupled to the sensors. The controller corrects for dispersion in the sensor signals and determines a location of the touch using the dispersion corrected signals. The controller performs impulse reconstruction, by which impulses representative of impulses generated by the touch to the touch sensitive device are produced. Using the reconstructed impulses, the controller confirms the location of the touch.

Abstract: A touch sensitive apparatus includes a touch plate to which several pickup sensors and at least one excitation transducer are coupled. Each of the sensors is configured to sense bending waves in the touch plate, and the excitation transducer is configured to induce bending waves in the touch plate. The apparatus may further include active buffer circuits, wherein each of the active buffer circuits is coupled to one of the sensors. A controller is coupled to the sensors via the active buffer circuits and to the excitation transducer via a non-actively buffered connection. The controller is configured to compute a location of a contact on the touch plate responsive to sense signals received from the sensors. The apparatus may be used to perform a variety of calibrations, including touch plate and sensor calibrations. Changes in touch sensing apparatus calibration and performance may be detected and tracked over time.

Abstract: A touch sensing device includes a plurality of sensors and an emitting transducer coupled to a touch panel. The transducer induces bending waves in the touch panel. The sensors sense bending waves in the touch panel and generate a bending wave signal responsive to the sensed bending waves. A controller identifies an untouched condition signal responsive to the induced bending waves. The controller compares the untouched condition signal to the bending wave signal, and detects a touch on the touch panel based on the comparison.

Abstract: The present invention provides a piezoelectric transducer that includes at least two poled piezoelectric regions disposed in a side-by-side arrangement and connected in series with the poling directions reversed through the series connection, meaning that the “north pole” of one region is connected to the “south pole” of an adjacent region. The at least two regions can be within the same piece of piezoelectric material, or can be separate pieces of piezoelectric material. Transducers of the present invention may be particularly suited to detecting vibrations such as bending waves in a plate. For example, transducers of the present invention may be affixed to a surface of a plate and used to detect vibrations caused by or affected by touches to the plate to determine information related to the touches, such a touch position.

Abstract: A privacy management system is disclosed for when a calling party has a private telephone number. Privacy screening services allow a subscriber to manage and monitor incoming telephone calls, such that unwanted calls are not terminated to the subscriber. When a calling party calls the subscriber to this privacy screening service, the privacy management system manages the call according to whether the calling party number is known and public, known and private, or unknown. If the calling party number is known and public, the call is routed to the subscriber. If, however, the calling party is known and private, an announcement is played to the calling party, asking the calling party for permission to override his or her privacy. If the calling party is unknown, the calling party is asked to record his/her name.

Abstract: A resonant bending wave loudspeaker comprising a panel-form acoustic radiator in the form of a beam and a vibration transducer mounted to the beam at a position to apply bending wave energy thereto to enable low frequency modes to be excited in the radiator both lengthwise of the radiator and crosswise of the radiator, and means mounting the radiator to permit the excitation of low frequency lengthwise and crosswise modes therein.

Abstract: Active acoustic device comprises a panel member (11) having distribution of resonant modes of bending wave action determining acoustic performance in conjunction with transducer means (31-34). The transducer means (31-34) is coupled to the panel member (11) at a marginal position. The arrangement is such as to result in acoustically acceptable action dependent on said distribution of active said resonant modes. Methods of selecting the transducer location, or improvement by location of localised marginal clamping, rely on assessing best or better operative interaction of said transducer means (31-34) and the panel members (11) according to parameters of acoustic output for the device as an acoustic radiator.

Abstract: An Audio Signal Processing system in which gain values are calculated for a plurality of output channels so that, from a notional listening position, a notional sound source may be perceived as being positioned anywhere within a notional listening space. First gain contributions arranged to make a predominant contribution when the perceived position is close to the notional listening position are calculated. Second gain contributions arranged to make a predominant contribution when the perceived positions are not close to the notional listening position are calculated. The first gain contributions and the second gain contributions are combined to produce combined gain values for each output channel.
