  • Patent number: 9711928
    Abstract: Single heterogeneous crystals are described that contain multiple regimes, adjacent regimes varying from one another with regard to function. Also disclosed is a hydrothermal epitaxial growth process that can be utilized to form the single heterogeneous crystals. The single heterogeneous crystals can exhibit enhanced performance when used as a laser gain medium as compared to previously known single crystals and multi-crystal constructs. The heterogeneous single crystal can be utilized for thin disk lasers and can minimize the thermal distortion effects at high powers. The heterogeneous crystal can also serve as an embedded waveguide.

  • Patent number: 9693867
    Abstract: Total knee replacements for hinged knee implants include a tibial member, a femoral member, a hinge assembly having a laterally extending axle configured to hingedly attach the femoral member to the tibial member, and a lock mechanism in communication with the hinge assembly. The lock mechanism is configured to (i) lock the femoral member in alignment with the tibial member for a full extension or other defined stabile walking configuration to thereby allow an arthrodesis or stiff knee gait and (ii) unlock to allow the femoral and tibial members to pivot relative to each other for flexion or bending when not ambulating.

  • Patent number: 9507367
    Abstract: A dynamic stochastic optimal power flow (DSOPF) control system is described for performing multi-objective optimal control capability in complex electrical power systems. The DSOPF system and method replaces the traditional adaptive critic designs (ACDs) and secondary voltage control, and provides a coordinated AC power flow control solution to the smart grid operation in an environment with high short-term uncertainty and variability. The DSOPF system and method is used to provide nonlinear optimal control, where the control objective is explicitly formulated to incorporate power system economy, stability and security considerations. The system and method dynamically drives a power system to its optimal operating point by continuously adjusting the steady-state set points sent by a traditional optimal power flow algorithm.
