  • Patent number: 6708163
    Abstract: A system and method for collective data mining from a distributed, vertically partitioned feature space as described. Collective data mining involves a unique approach for finding patterns from a network of databases, each with a distinct feature space. A distributed data mining system from heterogeneous sites is described. The architecture is ideal for accommodating different inductive learning algorithms for data analysis at different sites and includes a scalable approach using a gene expression-based evolutionary algorithm. This approach is used for distributed fault detection in an electrical power distribution network. Further implementations are also described.

  • Patent number: 6519271
    Abstract: A photonic quantum ring (PQR) laser diode with a plurality of laterally extending layers, one on top of another in an axial stack, comprises an active region sandwiched between an n type multi-layer distributed Bragg reflector (DBR) stack and a p type multi-layer DBR stack, wherein, along the circumference of said active region, 3 dimensional radiations are emitted with various wavelengths over a predetermined tuning range, as a function of slanted view angle with respect to the stack axis. The PQR laser shows an ultra-low threshold current of &mgr;A range, T½ dependence of the spectral peak shift and a square law behavior of threshold currents.
