A hybrid approach to improve handwriting recognition and voice recognition in data process systems is disclosed. In one embodiment, a front end is used to recognize strokes, characters and / or phonemes. The front end returns candidates with relative or absolute probabilities of matching to the input. Based on linguistic characteristics of the language, e.g. alphabetical or ideographic language for the words being entered, e.g. frequency of words and phrases being used, likely part of speech of the word entered, the morphology of the language, or the context in which the word is entered), a back end combines the candidates determined by the front end from inputs for words to match with known words and the probabilities of the use of such words in the current context.

Domains (multiple collaborating service providers) create service offerings between pairs of edge nodes that interconnect with other domains in the network. The service offerings may specify the available bandwidth, quality of service, reliability, available security, price, subscriber and service contextual specific and other SLA information. When a new service is to be created, the service definition is used along with information about the available service offerings to determine a set of networks to implement the service. Information associated with the service offerings may be flooded to all other networks. Alternatively, the service offering information may be provided to a trusted third party (SLA broker) which may provide SLA services on the network to select sets of domains to implement inter-domain services, and may also proxy to set up the service for the SLA requesting party. A hybrid approach may also be used wherein some SLA information is flooded and other information is retained in secret and provided only to the SLA broker.

A method for three-dimensional shape measurement may include (a) projecting a plurality of binary patterns onto at least one object; (b) projecting three phase-shifted fringe patterns onto the at least one object; (c) capturing images of the at least one object with the binary patterns and the phase-shifted fringe patterns; (d) obtaining codewords from the binary patterns; (e) calculating a wrapped phase map from the phase-shifted fringe patterns; (f) applying the codewords to the wrapped phase map to produce an unwrapped phase map; and (g) computing coordinates using the unwrapped phase map for use in the three-dimensional shape measurement of the at least one object. A system for performing the method is also provided. The high-speed real-time 3D shape measurement may be used in numerous applications including medical science, biometrics, and entertainment.

A dual LED and incandescent security lighting system uses a hybrid approach to LED illumination. It combines an ambient LED illuminator with a standard incandescent lamp on a motion control sensor. The LED illuminator will activate with the onset of darkness (daylight control) and typically remain on during the course of the night (“always on”). The LED illumination, typically amber, is sufficient to provide low to moderate level lighting coverage to the wall and ground area adjacent to and under the fixture. The incandescent lamp is integrated with a motion control circuit and sensor. When movement in the field of view is detected (after darkness), the incandescent lamp is switched on, providing an increased level of illumination to the area. Instead of an “always on” LED illuminator, the LEDs may also be switched off when the incandescent lamp is switched on.

Method and apparatus for combining a plurality of overlapping policy-based controllers. System also applicable to policy-based process servers. System combines controllers by combining the respective policy information. System combines a plurality of policy-based sub-controllers by combining the associated distributional information contained in the associated sub-policies. An iterative mixture mechanism with temporal persistence regulates the relative contribution of the sub-policies smoothly over time thereby allowing smooth transition of control from one control regime to another. The system provides for modular detection and resolution of conflicts that may arise as a result of combining otherwise incompatible sub-policies. Preferred embodiment performs mixture method in policy space. Another embodiment applies mixture method to value functions associated with each sub-server.

A scalable packet forwarding approach to speed up unicast and multicast routing-table lookups in the Internet which we refer to as "Cluster-based Aggregation Switching Technique" or "CAST". CAST integrates the use of two mechanisms: (i) organizing table entries into clusters and (ii) using cluster-label swapping so that packets can refer to specific clusters within which the routing-table lookup should take place. The motivation for introducing CAST is the escalating rate of improvement of Internet bandwidth available at backbone routers, which continues to exceed the maximum rate of packet processing power of high-speed routers. Simulations show that the hybrid approach used in CAST to expedite routing table lookups is more attractive for unicast routing than all prior approaches in terms of its lookup power and total memory size. Furthermore, CAST applies equally well to multicast routing, while many prior schemes do not.

Although self-driving vehicles excel under “normal” driving conditions, they sometimes struggle with new situations that often would not be overly difficult for a person. Several embodiments described herein enable a hybrid approach that leverages the exceptional abilities of self-driving vehicles while soliciting human interaction in select situations. The resulting combination of machine intelligence and human intelligence significantly enlarges the potential of self-driving vehicles in a manner that will enable self-driving vehicles to become widespread much faster than would otherwise be the case.

A hybrid method of predicting the occurrence of future critical events in a computer cluster having a series of nodes records system performance parameters and the occurrence of past critical events. A data filter filters the logged to data to eliminate redundancies and decrease the data storage requirements of the system. Time-series models and rule based classification schemes are used to associate various system parameters with the past occurrence of critical events and predict the occurrence of future critical events. Ongoing processing jobs are migrated to nodes for which no critical events are predicted and future jobs are routed to more robust nodes.

A hybrid approach for capturing meta data about Business Processing Monitoring (BPM) artifacts is based on a combination of a relational meta data model and a semantic net. Meta data about metrics and situations and their dimensional context are first captured. Then, relational meta data are used to describe a generic data schema for metrics, situations and their dimensional context. The meta data from semantic nets are used to extend the meta data definitions. Data from a data warehouse are searched and managed with the schema described and managed with the relational and semantic net meta data.

A system and method are provided for XML query cursor implementation through the steps of query translation and processing, query result navigation, and positioned update. An XML query cursor implemented in Interface Definition Language (IDL) as well as an extension to XQuery, an XML query language, is described. These steps are addressed by one of three approaches: multi-cursor, outer union, or hybrid. In each approach, XML data is assumed to be stored in a relational database with a mapping that maps each element to a row in a relational database table. In each approach, a system and method provide for cursor movements and positioned updates in increments of a node, sub-tree, or entire document. Given a user's navigation patterns, a system and method is provided to select either a multi-cursor, outer union, or hybrid approach as an optimal implementation for an XML query cursor.

An audio spatial environment engine is provided for converting between different formats of audio data. The audio spatial environment engine (100) allows for flexible conversion between N-channel data and M-channel data and conversion from M-channel data back to N′-channel data, where N, M, and N′ are integers and where N is not necessarily equal to N′. For example, such systems could be used for the transmission or storage of surround sound data across a network or infrastructure designed for stereo sound data. The audio spatial environment engine provides improved and flexible conversions between different spatial environments due to an advanced dynamic down-mixing unit (102) and a high-resolution frequency band up-mixing unit (104). The dynamic down-mixing unit includes an intelligent: analysis and correction loop (108, 110) capable of correcting for spectral, temporal, and spatial inaccuracies common to many down-mixing methods. The up-mixing unit utilizes the extraction and analysis of important inter-channel spatial cues across high-resolution frequency bands to derive the spatial placement of different frequency elements. The down-mixing and up-mixing units, when used individually or as a system, provide improved sound quality and spatial distinction.

Systems and methods for implementing hybrid, closed-loop control that generates control values for processes defined by a limited number of function evaluations and large amounts of process and measurement noise. The described control system is applied to a stencil printing process for applying solder paste to an electronic medium such as a printed circuit board or semiconductor wafer. The control system is defined by a hybrid approach. A first, coarse algorithm is used to rapidly produce the value of a stencil printer control value resulting in a solder paste deposit having a volume within predetermined acceptable limits. After the coarse algorithm no longer produces solder paste deposits closer to a desired volume, a second, more refined estimator is used to fine tune the process. An additional transitional algorithm may be added between the coarse algorithm and refined estimator. The coarse algorithm may be implemented with a constrained-conjugated gradient search, and the refined search may be a implemented using a least-squares affine estimator or a quadratic estimator. The transitional algorithm may be implemented using a block version of a least-squares affine estimator.

A hybrid method for dental implant treatment planning and a corresponding approach to make a surgical guide. After digital treatment planning is performed with CT scan data, a master model is created, which embodies the patient anatomy and entire treatment plan. Jaw bone, tooth surfaces, soft tissues and nerves are all contained by the master model. The plan details including implant sizes and positions, surgical guide drill options, as well as the choice of a surgical kit, are all conveyed by the master model. Meanwhile, models of specially designed “implant inserts (or replicas)” are also generated, which have one end that fits into the implant holes on the master model and another end to make the surgical guide. The master model and inserts are manufactured with rapid prototyping technology. A surgical guide is later on made from them with conventional lab processes. A main characteristic of this approach is that the master model and the inserts are the physical embodiment of a virtual treatment plan. With them, the surgeons can continue the treatment planning for operations like tooth extractions and bone modifications before making the surgical guides. Therefore the treatment planning workflow is a combination of digital treatment planning and a physical model based planning, in other words, a hybrid approach. A differentiator in this invention is the generation of a closed solid model of the soft tissue, as part of the master model, from the scan data. This approach can be applied to create both bone-borne and tissue-borne surgical guides with low cost process, which is a big advantage over other approaches.

The present disclosure concerns a hybrid content-based 3D model search and retrieval method for queries in generic 3D model datasets. The hybrid nature of the method is two-fold. First, a combination of 2D and 3D features is used as the shape descriptor of a 3D model and second, two alternative alignment techniques, CPCA and NPCA, are employed for rotation normalization. The 2D features are Fourier coefficients extracted from three pairs of depth buffers which are computed for each Cartesian plane capturing the model's thickness along each axis. The 3D features are spherical harmonic coefficients extracted from a spherical function based representation that captures the model's surface as well as volume information.

Method for simultaneous full-wavefield inversion of gathers of source (or receiver) encoded geophysical data to determine a physical properties model for a subsurface region, especially suitable for surveys where fixed receiver geometry conditions were not satisfied in the data acquisition. First, a shallow time window of the data (202) where the fixed receiver condition is satisfied is inverted by simultaneous encoded (203) source inversion (205). Then, the deeper time window of the data (208) is inverted by sparse sequential source inversion (209), using the physical properties model from the shallow time window (206) as a starting model (207). Alternatively, the shallow time window model is used to simulate missing far offset data (211) producing a data set satisfying the stationary receiver assumption, after which this data set is source encoded (212) and inverted by simultaneous source inversion (214).

Mobile nodes communicate with each other to transfer packets between a source and a destination using a multi-hop network strategy for communicating packets in the forward direction and using a mobile infostation network strategy, alone or in combination with a multi-hop network strategy, for communicating packets in the reverse direction, thereby exploiting a controlled flooding communication scheme that balances the tradeoffs between capacity improvement and random packet delay. The system may be used in a variety of applications, including an intelligent highway information system.

The present invention relates to a system and method for positioning and navigation using hybrid spectral compression and cross correlation signal processing of signals of opportunity, which may include Global Navigation Satellite System (GNSS) as well as other wideband energy emissions in GNSS obstructed environments. Examples of these signals of opportunity include but are not limited to GPS, GLONASS, cellular Code Division Multiple Access (CDMA) communications signals, and 802.11 Wi-Fi. Combining spectral compression with spread spectrum cross correlation enables extraction of code and carrier observables without the need to implement the tracking loops (e.g. Costas tracking loop) commonly used in conventional GNSS receivers. For applications where dynamics and transmission medium may make it difficult to continuously track carrier phase, the hybrid approach of the present invention has significant utility.

New articles can be applied against the trained model, and classified.

A hybrid approach is provided to the formatting of signals for transmission in a high-data-rate wireless system. We retain the format and timing of an HRPD frame, but the data portions of selected slots within the frame are given over to OFDMA transmission instead of CDMA transmission. Because OFDMA is robust against self-interference, high throughput can be achieved in a greater number of slots, including at least some in which a low signal-to-interference-noise ratio (SINR) might limit a pure CDMA data rate.
