  • Publication number: 20200340282
    Abstract: A power closure actuator for powering a movable closure includes an output member configured to drive movement of the movable closure, a motor coupled through a gear reduction to drive the output member, and an integrated brake-clutch unit having an input configured to receive drive power from the electric motor. The brake-clutch unit provides independent braking and clutching between the electric motor and the output member via an electric brake actuator and an electric clutch actuator, respectively. Brake and clutch portions of the brake-clutch unit act on a rotor, and brake force can be maintained on the rotor without powering the brake actuator. A clutch disc is biased disengaged from the rotor. The integrated brake-clutch unit provides a drive state between the electric motor and the output member when the brake portion is released concurrently with the clutch portion establishing a power coupling between the clutch disc and the rotor.

  • Patent number: 7574306
    Abstract: One embodiment of the present invention is directed to a method and system for designing the monomer sequence of a polymer to produce a particular polymer that adopts an initially specified, 3-dimensional conformation in a specified chemical environment. In one specific embodiment, the method and system produces amino-acid sequences for polypeptides in order to generate polypeptides that adopt initially specified, 3-dimensional conformations. Additional embodiments determine sequences for various other types of biopolymers in order to produce biopolymers that adopt specific conformations in specified chemical environments. For example, these method embodiments may be used to design sequences for polysaccharides, polynucleotides, and hybrid biopolymers.
