Patent number: 6999601Abstract: A target in a sequence of measurements is tracked by modeling the target with a switching linear dynamic system (SLDS) having a plurality of dynamic models. Each dynamic model is associated with a switching state such that a model is selected when its associated switching state is true. A set of continuous state estimates is determined for a given measurement, and for each possible switching state. A state transition record is then determined by determining and recording, for a given measurement and for each possible switching state, an optimal previous switching state, based on the measurement sequence, where the optimal previous switching state optimizes a transition probability based on the set of continuous state estimates. A measurement model of the target is fitted to the measurement sequence. The measurement model is the description of the influence of the state on the measurement. It couples what is observed to the estimated target.Type: GrantFiled: September 12, 2003Date of Patent: February 14, 2006Assignee: Hewlett-Packard Development Company, LPInventors: Vladimir Pavlovic, James Matthew Rehg

Publication number: 20040236518Abstract: Computer based apparatus and method automates gene prediction in a subject genomic sequence. A plurality of expert systems provide preliminary or intermediate gene predictions. A Bayesian network combiner combines the intermediate gene predictions and forms a final gene prediction. The final gene prediction accounts for dependencies between individual expert systems and dependencies between adjacent parts of the subject genomic sequence.Type: ApplicationFiled: June 30, 2004Publication date: November 25, 2004Applicant: Hewlett-Packard Development Company, L.P.Inventors: Vladimir Pavlovic, Simon Kasif, Ashutosh Garg

Publication number: 20040042639Abstract: Portions of an input measurement sequence are classified into a plurality of regimes by associating each of a plurality of dynamic models with one a switching state such that a model is selected when its associated switching state is true. In a Viterbi-based method, a state transition record is determined, based on the input sequence. A switching state sequence is determined by backtracking through the state transition record. Finally, portions of the input sequence are classified into different regimes, responsive to the switching state sequence. In a variational-based method, the switching state at a particular instance is also determined by a switching model. The dynamic model is then decoupled from the switching model. Parameters of the decoupled dynamic model are determined responsive to a switching state probability estimate. A state of the decoupled dynamic model corresponding to a measurement at the particular instance is estimated, responsive to the input sequence.Type: ApplicationFiled: September 16, 2003Publication date: March 4, 2004Inventors: Vladimir Pavlovic, James Matthew Rehg

Patent number: 5923712Abstract: A system for linearly transmitting an amplified output signal using predistortion whereby a straight inverse modeling scheme is used to more easily and accurately determine the inverse of the distortion caused by a power amplifier of a RF transmitter. The "inverse" of the power amplifier is directly modeled by considering the power amplifier as a signal processing block with the input and output ports reversed. As a result, the computationally intensive inversion required by conventional schemes is avoided. The predistorter system stores complex coefficients in a predistorter LUT, which are then used as the tap weights of a digital filter implementing the predistorter. The predistortion is done by a non-linear filter which incorporates both instantaneous and average envelope power or magnitude effects. The predistortion LUT is addressed as a function of the instantaneous envelope power or magnitude and past power or magnitude envelopes.Type: GrantFiled: May 5, 1997Date of Patent: July 13, 1999Assignee: Glenayre Electronics, Inc.Inventors: Robert Richard Leyendecker, Jay Jui-Chieh Chen, Armando Cova Garrido, Yan Guo, Vladimir Pavlovic, Claudio Gustavo Rey, Desmond Wai Ming Yan

Patent number: 5732333Abstract: A linear transmitter (101) using predistortion includes a modulator (103), a predistorter (107), a digital quadrature modulator (111), an upconverter (113), a power amplifier (115), and an antenna (117). In addition, the transmitter (101) has a feedback loop including a coupler (119), a downconverter (123), a digital quadrature demodulator (125), and a trainer (131). The digital data to be transmitted is provided into the modulator (103), which converts the digital data into in-phase and quadrature component signals. The in-phase and quadrature component signals are then provided to the predistorter (107), which "predistorts" the component signals prior to amplification. The digital quadrature modulator (111) converts the component signals into a single analog signal. The upconverter (113) upconverts this signal from the predistorter (107) into the desired frequency of transmission, which is provided to the power amplifier (115) and the antenna (117) for amplification and broadcast.Type: GrantFiled: February 14, 1996Date of Patent: March 24, 1998Assignee: Glenayre Electronics, Inc.Inventors: Charles Brian Cox, David Kent Bonds, Jay Jui-Chieh Chen, Flaviu C.
