  • Patent number: 10699834
    Abstract: Electromagnetic locking devices, systems, and methods are provided. The electromagnetic locking devices, systems, and methods are configured to lock an actuating arm of an actuator in any desired position between and including a fully extended position and a fully retracted position with respect to an outer cover of the electromagnetic locking device and/or system. The electromagnetic locking devices, systems, and methods described herein may include an unpowered deformable member that imparts fail-safe functionality thereto.
    Type: Grant

  • Publication number: 20180195563
    Abstract: Motion control systems, devices, and methods are operable for controlling rotary motion of an actuated device. In one aspect, a motion control device is coupled between an external motive input (200) and a rotary output device (300). The motion control device has a brake core (110) configured to produce an electromagnetic field when an electric current is applied. A brake band (130) made of a magnetically responsive material surrounds the brake core (110) and is coupled to the brake core (110) when the electric current is applied. A rotor (120) that is coupled to both the external motive input (200) and the rotary output surrounds at least the perimeter of the brake band (130) and is coupled to the brake band (130) for rotation together. When the electric current is applied, the rotor (120) and the brake core (110) are thus rotatably locked together to control rotary motion generated by actuating forces imparted by the external motive input (200).

  • Patent number: 9206271
    Abstract: Functionalized degradable ROMP (ring-opening metathesis) polymers and methods, starting monomers and synthetic monomeric and polymeric intermediates for preparation of such functionalized polymers. More specifically, monomers having a bicyclic oxazinone structure, a bicyclic urea, or a heteronorbornene core structure, among others, have been found to be substrates for ROMP polymerization. ROMP polymers prepared from these monomers have been found to be both acid and base labile. Additionally, the monomers can be chemically modified at a site distal to the polymerizable moieties and bridgehead carbons. The properties of the resulting polymers and copolymers can be tailored without destabiling the monomer. Polymers and copolymers of the invention are degradable but have a glass temperature of 100° C. or more.
