Abstract: A system and method for improving speech recognition accuracy in the presence of noise is provided. The speech recognition training unit is modified to store digitized speech samples into a speech database that can be accessed at recognition time. The improved recognition unit comprises a noise analysis, modeling, and synthesis unit which continually analyzes the noise characteristics present in the audio environment and produces an estimated noise signal with similar characteristics. The recognition unit then constructs a noise-compensated template database by adding the estimated noise signal to each of the speech samples in the speech database and performing parameter determination on the resulting sums. This procedure accounts for the presence of noise in the recognition phase by retraining all the templates using an estimated noise signal with similar characteristics as the actual noise signal that corrupted the word to be recognized.

Abstract: A pharmacy drug management system provides pharmacy drug management software for patient-specific drug dosing, drug interaction analysis, order generation, and patient data matching. When a drug is added for a patient, the system detects if the drug is a doser drug requiring precise therapeutic dosing and also detects if the drug will cause any drug interaction problems for the patient, reducing the likelihood of clinical misjudgments. The system checks for drug interaction problems resulting from drugs, food allergies, and the medical condition of the patient. An on-screen order may then be generated. A doctor or pharmacist thus is aware of any drug interaction problems before writing an order for the patient. If a selected drug is a doser drug, the system uses phannacokinetic equations specific to the patient data to calculate the appropriate therapeutic dosing parameters.

Abstract: Power industry boiler tube failures are a major cause of utility forced outages in the United States, with approximately 41,000 tube failures occurring every year at a cost of $5 billion a year. Accordingly, early tube leak detection and isolation is highly desirable. Early detection allows scheduling of a repair rather than suffering a forced outage, and significantly increases the chance of preventing damage to adjacent tubes. The instant detection scheme starts with identification of boiler tube leak process variables which are divided into universal sensitive variables, local leak sensitive variables, group leak sensitive variables, and subgroup leak sensitive variables, and which may be automatically be obtained using a data driven approach and a leak sensitivity function. One embodiment uses artificial neural networks (ANN) to learn the map between appropriate leak sensitive variables and the leak behavior.

Abstract: An electronic system interconnect. The interconnect comprises a first node and a second node coupled to the first node. The interconnect is initially configured to include the first and second nodes. A third node is added to the interconnect after the interconnect is initially configured, and the first node responds to the addition of the third node by initiating a new connect handshake with the third node. The first node begins by transmitting a first signal to the third node. The first node signals that the third node has been added to the interconnect if the third node responds to the first signal by transmitting a second signal. The first node causes the interconnect to be reconfigured if the third node transmits a third signal in response to receiving the first signal.

Abstract: Public key security control (PKSC) is provided for a cryptographic module by means of digitally signed communications between the module and one or authorities with whom it interacts. Authorities interact with the crypto module by means of unsigned queries seeking nonsecret information or signed commands for performing specified operations. Each command signed by an authority also contains a transaction sequence number (TSN), which must match a corresponding number stored by the crypto module for the authority. The TSN for each authority is initially generated randomly and is incremented for each command accepted from that authority. A signature requirement array (SRA) controls the number of signatures required to validate each command type. Upon receiving a signed command from one or more authorities, the SRA is examined to determine whether a required number of authorities permitted to sign the command have signed the command for each signature requirement specification defined for that command type.

Abstract: A system is provided for filtering out potentially objectionable content from a video. The system is preferably implemented with user equipment such as a set-top box, a dedicated stand-alone box, a videocassette recorder, or circuitry in other television equipment. Videos to be filtered have embedded information that identifies potentially objectionable substitution events. The system determines which substitution events are to be filtered out based on selectable ratings settings. If desired, filtered video images may be replaced with blank video images and filtered audio signals may by replaced with silence or a tone. Filtering may also be accomplished by disrupting the event to be filtered (e.g., by garbling the event). Filtering may involve making substitutions of audio or video information. For example, audio information in a substitution event may be replaced by appropriate audio segments. Video information in a substitution event may be replaced by a video still or by a video clip.

Abstract: An interactive entertainment system enables presentation of supplemental interactive content along side traditional broadcast video programs, such as television shows and movies. The programs are broadcast in a conventional manner. The supplemental content is supplied as part of the same program signal over the broadcast network, or separately over another distribution network. A viewer computing unit is located at the viewer's home to present the program and supplemental content to a viewer. When the viewer tunes to a particular channel, the viewer computing unit consults an electronic programming guide (EPG) to determine if the present program carried on the channel is interactive. If it is, the viewer computing unit launches a browser. The browser uses a target specification stored in the EPG to activate a target resource containing the supplemental content for enhancing the broadcast program.
