A method for setting up a conference call where the subscribers are not only concentrated in one area but also more widely dispersed. The method allows both groups of subscribers to be contacted for a conference call with individuals close to the point of origination of the conference call being connected to a shared channel call and any members further out being connected to the conference call using individual channels. Members who initially started with an individual channel can move closer to the point of origin and automatically join the shared channel. This is of particular use to the emergency services where they may need to co-ordinate members arriving at the scene or performing related actions further away from the scene of the emergency.

In exemplary embodiments of the present invention, based upon the assigned position of the cursor or icon in 3D, the functionality of a selected tool, and whether and in what sequence any buttons have been pressed on a 2D interface device, a variety of 3D virtual tools and functionalities can be implemented and controlled by a standard 2D computer interface.

A method and apparatus for steering of a flexible needle into tissue using a steering robotic platform for manipulation of the needle shaft, and by use of a semi-active arm for locating and orienting of the steering robot on the patient's body. As opposed to other steering methods, the robot does not hold the base of the needle, which is its proximal region, but rather grips the shaft of the needle by means of a manipulatable needle gripping device, near its distal end. The needle gripper attached to the robotic platform may be equipped with a traction assembly to provide motion to the needle in its longitudinal direction, such that it co-ordinates the entry of the needle with the desired entry angle. The gripping of the needle at its distal end, close to its insertion point, provides the needle manipulator with a low profile, with concomitant advantages.

A first device, such as a PC, is enabled to receive messages from a second device, such as an application server, that does not know the address of the first device, by interaction with an intermediate man-in-the-middle (MITM) server. The first device obtains an ID, provides the ID to a human using the first device, and then the human provides the ID to the second device. The second device sends a message to the MITM server addressed to the ID. Meanwhile, the first device long polls the MITM server, and in response to one of the long polls, the MITM server sends the message from the second device to the first device. The first device is operating according to a script that was received from an external device, in response to a request for the script from the first device. The request for the script is embedded in a web page that the first device received; the script request may be launched automatically by the web page or in response to an action by the human. The human perceives an interaction experience co-ordinated across devices.

Thereby it is possible to create a very compact representation of a model of a geometrical object. The model-prima facia-seems to be constrained very hard, but is in fact a very flexible and easy to access model.

The invention relates to a method for displaying three-dimensional images. In the method light beams (Le) are associated to several different screen points (P) of a screen (20). The light beams (Le) produce different views associated to different emission directions (E). The emission directions (E) are associated to the individual screen points (P). The light beams (Le) are generated by projecting light beams (Ld), according to the angle of the adjacent emitting directions. According to the invention, light beams (Le) without viewing direction information are generated, essentially simultaneously, with pixels (Cd) having different co-ordinates. These pixels (Cd) are pixels of a two-dimension display (50), and they are associated to different emitting directions (E) of the appropriate screen points (P). The light beams (Le) produced by the pixels (Cd) of the display (50) with different co-ordinates are imaged simultaneously in different deflection directions (D), as a function of the co-ordinates of the pixels (Cd) producing the light beams (Le). The subject of the invention is an apparatus implementing the above method.

A debugger is also provided which is operable to control operation of a processing unit associated with the system under verification, the processing unit being operable to execute software routines. A debugger signal interface controller is arranged to interface with the debugger and to perform one or more test actions transferring at least one of one or more stimulus signals and one or more response signals between the debugger and the debugger signal interface controller during performance of the sequence of verification tests. A test manager coupled to the plurality of signal interface controllers and the debugger signal interface controller is operable to transfer test controlling messages to these interface controllers identifying the test actions to be performed. By this approach, the test manager is operable to control the operation of the processing unit via the debugger signal interface controller and the debugger in order to co-ordinate the execution of the software routines with a sequence of verification tests. This has been found to be a particularly efficient technique for performing hardware and software co-verification.

Brain images are processed and analyzed with the aid of a computer for stroke diagnosis or therapeutic decision making, where multiple stroke-related images are superimposed. The superimposed images include brain images that have infarct and penumbra regions, and patient-specific brain atlas images. The infarct and penumbra regions are determined and delineated on the superimposed images. Each patient-specific brain atlas image may be formed by mapping a pre-existing brain atlas to a co-ordinate system in which the brain images are co-registered. A brain atlas may depict brain structures such as anatomy structures, blood supply territories (BST), or cerebral vasculature. The superimposed images may be used to determine any overlap between a particular brain structure and the infarct and penumbra regions.

A computer system is provided including a control module 20 and data collection module 22 which generate user interfaces enabling a user to identify a vocabulary and a number of speakers from whom utterances are to be obtained. The data collection module 22 then co-ordinates the collection of utterance data for the words in the vocabulary from these speakers and stores the data in a speaker database 24. When a satisfactory set of utterances have been collected the utterances are passed to a model generation module 25 which generates a speech model using the utterances. The speech model is stored by the model generation module 25 in a model database 26. The generated model stored within the model database 26 can then be tested using a testing module 27 and other utterances stored within the speaker database 24. If the performance of the model is unsatisfactory further or different utterances can be used to generate new models for storage within the model database 26. When a speech model is determined to be satisfactory the control module 20 can invoke the output module 28 to output a copy of the model.
