Abstract: Novel lipid-nucleic acid particulate complexes which are useful for in vitro or in vivo gene transfer are described. The particles can be formed using either detergent dialysis methods or methods which utilize organic solvents. Upon removal of a solubilizing component (i.e., detergent or an organic solvent) the lipid-nucleic acid complexes form particles wherein the nucleic acid is serum-stable and is protected from degradation. The particles thus formed have access to extravascular sites and target cell populations and are suitable for the therapeutic delivery of nucleic acids.

Abstract: The invention provides a method for dynamically changing the loop bandwidth of a closed loop control system. At least one loop bandwidth parameter controls the loop bandwidth of the closed loop control system. An error signal reflecting the convergence status of the output signal of the closed loop control system is first detected. The at least one loop bandwidth parameter is then dynamically adjusted according to the error signal to change the loop bandwidth of the closed loop control system. A feedback signal of the closed loop control system is then generated according to the loop bandwidth. Finally, an input signal of the closed loop control system is compensated with the feedback signal to generate the output signal.

Abstract: A brake mechanism (10) for an elevator (2) is activated in response to an electronic control signal to prevent movement of an elevator car (16) under predetermined conditions. The brake mechanism is preferably a safety mechanism (10) and does not require a governor sheave, a governor rope, or a tension sheave. The safety mechanism in one disclosed example utilizes a solenoid actuator (22b) and an electric motor (40) and gear box assembly (42) to move safety wedges (18) into engagement with a guide rail (20) to stop the elevator car (16). The safety wedges (18) are held in a non-deployed position during normal elevator operation. If there is a power loss or if elevator car speed exceeds a predetermined threshold, an electronic control signal activates the safety mechanism (10) causing the solenoid to release, which causes the safety wedges (18) move in a direction opposite to that of a safety housing (12) mounted for movement with the elevator car (16).
