Abstract: Systems and methods for a WEC controller that uses a self-tuning proportional-integral control law prescribing motor torques to maximize electrical power generation and automatically tune the controller to maximize power absorption. In an embodiment, the controller may be part of any resonant WEC system. The control law relies upon an identified model of device intrinsic impedance to generate a frequency-domain estimate of the wave-induced excitation force and measurements of device velocities. The control law was tested in irregular sea-states that evolved over hours (a rapid, but realistic time-scale) and that changed instantly (an unrealistic scenario to evaluate controller response).

Abstract: A cargo organizer is constructed from one or more bi-stable strips with at least one shape memory alloy (SMA) actuator per bi-stable strip. The cargo organizer can reside in the bi-stable strips elongated (flat) stable state and require little or no volume of the cargo compartment that it resides. Upon actuating a SMA actuator, the rapid conversion to the curved stable state can occur with the formation of a barrier to partition the cargo compartment into at least to portions. The transformation into the flat stable state removes the partition where the transformation can be via a second SMA actuator or manually. The cargo organizer can be incorporated into the cargo compartment in a manner that it translates from one site and orientation to one or more other sites or orientations by activation an actuator that can be an additional SMA actuator.

Abstract: Apparatus and associated methods relate to an airfoil configured to be disposed at a distal end of a tank. In an illustrative example, the airfoil may be configured such that, when the tank travels at a predetermined minimum speed in a proximal direction substantially parallel to a longitudinal axis of the tank, the airfoil coalesces off-coming air from the tank and distally repositions a low-pressure region downstream of the tank below a plane horizontal to the longitudinal axis. The region may be distally displaced, for example, by at least one of a length scale of the tank. A cross-section of the tank may, for example, define a substantially conic section. A span of the wing may, for example, be orthogonal to the longitudinal axis. The wing may, for example, be below an upper surface of the tank. Various embodiments may advantageously reduce turbulence in the wake of the tank.

Abstract: Embodiments of the present disclosure provide a method for control-flow integrity protection, including: changing preset bits of all legal target addresses of a current indirect branch instruction in a control flow of a program to be protected to be same; and rewriting preset bits of a current target address of the current indirect branch instruction to be same as the preset bits of the legal target addresses, so that the program to be protected terminates when the current target address is tampered with. By changing the preset bits of all the legal target addresses of the current indirect branch instruction to be same and rewriting the preset bits of the current target address to be consistent with the preset bits of the legal target addresses, traditional label comparison is replaced by the preset bit overlap operation, reducing performance overhead and improving attack defense efficiency.
