A spoken language interface comprises an automatic speech recognition system and a text to speech system controlled by a voice controller. The ASR and TTS are connected to a telephony system which receives user speech via a communications link. A dialogue manager is connected to the voice controller and provides control of dialogue generated in response to user speech. The dialogue manager is connected to application managers each of which provide an interface to an application with which the user can converse. Dialogue and grammars are stored in a database as data and are retrieved under the control of the dialogue manager and a personalisation and adaptive learning module. A session and notification manager records session details and enables re-connection of a broken conversation at the point at which the conversation was broken.

An apparatus for needle biopsy with real time tissue differentiation using one dimensional interferometric ranging imaging, comprising a biopsy device having a barrel and a needle, an optical fiber inserted in the needle, and a fiber optic imaging system connected to the optical fiber. The imaging system obtains images and compares the optical properties and patterns to a database of normalized tissue sample images to determine different tissue types. The physician performing the biopsy obtains feedback via a feedback unit associated with the biopsy device and which is connected to the imaging system. The feedback unit can provide visual, audible or vibratory feedback as to tissue type encountered when the needle is inserted toward the target tissue. The feedback unit can be programmed for different biopsy procedures so that the user can actuate a button to select a display or other feedback mechanism for the desired procedure and anticipated tissue to be encountered.

A system and method of determining and reporting on the position of a wireless device relative to a group of other wireless devices dispersed within a specified geographic area. The system includes at least one Query Unit, three or more Responding Units disposed at determinable locations within the specified geographic area, and one or more Mobile Units, which may correspond to additional Responding Units or units that function only as receivers. The Query Unit sequentially queries the Responding Units, and, responsive to the respective query messages, the Responding Units transmit corresponding response messages. One or more of the Mobile Units receive the query and response messages, and generate, for each query-response message pair, a set of time-difference-of-arrival (TDOA) measurements, which are used by the Mobile Units to determine their positions relative to the Responding Units. The Mobile Units record the times-of-arrival (TOAs) of the query message and the response messages at their respective receivers, and calculate the TDOAs based on the recorded TOAs. The TDOAs are then analyzed to determine the time differences due to the differences in lengths of the respective message propagation paths. The position of each Mobile Unit can then be computed using computation techniques typically employed in Long Range Navigation (LORAN) receivers, or any other suitable computation technique.

A touchscreen controller system determines the actual locations of multiple simultaneous touches by eliminating mutual capacitance between adjacent rows and columns during self-capacitance measurements and selectively enabling mutual capacitance during mutual capacitance measurements. During the self-capacitance measurements, the controller system generates a set of candidate touch locations, which includes the locations of real and ghost touches. During the mutual capacitance measurements, only the locations in the candidate set are measured and, from these measurements, the actual touch locations are determined. By limiting the mutual capacitive measurements to only a small subset of the locations over the entire touch panel, real touch locations are determined on a linear order. Also, by using on-chip integration capacitors, embodiments of the invention are able to perform each measurement in a single cycle.

An adaptive pre-equalizer is disclosed to compensate amplitude ripples in a low cost transmitter pass-band filter. A filtered-x LMS algorithm is proposed to calculate the equalizer coefficients. To this purpose, the modulated RF signal is demodulated at the transmitter and subtracted from a filtered version of the original base band signal. The impulse response of the low-cost transmit filter is approximated by a delay. The disclosure may be applied to direct conversion or heterodyne transmitters using OFDM.

A system and method for facilitating increased graphics processing without deadlock. Embodiments of the present invention provide storage for execution unit pipeline results (e.g., texture pipeline results). The storage allows increased processing of multiple threads as a texture unit may be used to store information while corresponding locations of the register file are available for reallocation to other threads. Embodiments further provide for preventing deadlock by limiting the number of requests and ensuring that a set of requests is not issued unless there are resources available to complete each request of the set of requests. Embodiments of the present invention thus provide for deadlock free increased performance.

The disclosure describes a method of progressively decoding a digital watermark on a distributed computing platform. A client device equipped with a digital camera, such as a PDA or cell phone, captures a digital image of a watermarked object, and pre-filters the image to isolate a portion of the image data suspected of containing a digital watermark. The pre-filter de-correlates a portion of the image data suspected of containing a digital watermark from the remaining host image signal using a predictive filter. The client then quantizes the filtered data and progressively transmits the quantized data to a watermark decoder. The progressive transmitter sends image data as necessary to achieve a valid decoding operation. To reduce bandwidth requirements, the transmitter starts with the most highly quantized version of the filtered image, and sends lesser quantized versions until the watermark decoder completes a successful decoding operation.

A system and method for establishing a pairwise temporal key (PTK) between two devices based on a shared master key and using a single message authentication codes (MAC) algorithm is disclosed. The devices use the shared master key to independently compute four MACs representing the desired PTK, a KCK, and a first and a second KMAC. The Responder sends its first KMAC to the Initiator, which retains the computed PTK only if it verifies that the received first KMAC equals its computed first KMAC and hence that the Responder indeed possesses the purportedly shared master key. The Initiator sends a third message including the second KMAC to the Responder. The Responder retains the computed PTK only if it has verified that the received second KMAC equals its computed second KMAC and hence that the Initiator indeed possesses the purportedly shared master key.

Data communication in network traffic is modeled in real time and is analyzed using a 2-state Markov modified Poissen process (MMPP). The traffic inter-arrival times for bursty and idle states define a transition window [λ1max, λ2min] represented by the boundary values λ1max max for the inter-arrival time for bursty traffic, and λ2min for the inter-arrival time for idle traffic. Changes in the values of λ1max and λ2min are tracked over time, and the size of the transition window is enlarged or decreased based upon relative changes in these values. If the inter-rival times for the bursty state and the idle state become approximately equal, the model defaults to a single state model. The modeling is applicable to the synchronization of polling and blocking in a low-latency network system. This permits the adoptive selection of poll or block to maximize CPU utilization and interrupt latency.
