Abstract: A processor-implemented method for simultaneously tracking one or more objects includes receiving, via a dynamical system with a set of sensors, a first set of unlabeled measurements from one or more objects. Each of the measurements is a function of time. A set of candidate tracks is determined for the one or more objects. Probabilities of each of the first set of unlabeled measurements being assigned to each of the set of candidate tracks are computed. A track from the set of candidate tracks is determined for each of the one or more objects based on a joint probability distribution of track attributes and the probabilistic assignment of each of the first set of unlabeled measurements to each of the set of candidate tracks.

Abstract: In an apparatus for determining the state of a system in which several system components undergo respective changes simultaneously, sensor measurements obtained from the components and candidate paths representing the individual states of the different components are analyzed. In this analysis, the system state is modeled in terms of likelihoods that certain paths correspond to true parameterized paths representing individual states of the system components and likelihoods that certain observations are associated with certain components. An optimization of the model provides accurate values of each type of likelihood, which then indicate the likely state of the system.

Abstract: A technique for measuring properties of a material includes measuring the electromagnetic radiation scattered by one or more scattering points associated with the material, and adjusting the radiation according to the respective sensitivities of the scattering points to changes in material properties at that scattering point for several pairs of radiation sources and receivers. The material properties are determined using the updated measurements and corresponding simulated measurements.

Abstract: A workflow system includes a workflow database. The workflow database may convert proposals or bids into a workflow process. The workflow process may involve one or more tasks which are performed by resources. The workflow database may have access to systems, or provide a system to interface with resources, contractors, vendors, billing departments, and generate reports of workflow process.

Abstract: A technology for wavelength division multiplexing light of a plurality of different wavelengths into one or more optical fibers is disclosed. In a first main embodiment, the light is multiplexed and turned by a designated angle using two lens arrays and a flat surface that functions as a mirror. In a second embodiment, a waveguide-based combiner structure multiplexes and turns a plurality of light beams of different wavelengths.
