  • Publication number: 20180327640
    Abstract: Presently described are methods of preparing a pressure sensitive adhesive composition comprising providing a non-aqueous pressure sensitive adhesive comprising a (meth)acrylic copolymer comprising epoxy-functional groups; adding a chlorinated triazine crosslinker to the pressure sensitive adhesive; and coating the pressure sensitive adhesive onto a substrate. In some embodiments, the method may further comprise contacting the pressure sensitive adhesive to a second substrate. The method further comprises exposing the pressure sensitive adhesive to actinic radiation to crosslink the epoxy-functional groups by means of the triazine crosslinker. The step of exposing can occur at the time of manufacture (e.g. of a pressure sensitive adhesive coated articles such as a tape) or at the time of use. Also described are non-aqueous pressure sensitive adhesive compositions and adhesive-coated articles.

  • Patent number: 10071721
    Abstract: A control method and apparatus of a hybrid vehicle are provided. The control method includes determining whether the speed of a motor exceeds a first threshold value, when supply of power to a battery is cut off and thus the hybrid vehicle is driven by an engine. The speed is then adjusted to be the first threshold value or less, when the speed exceeds the first threshold value.

  • Patent number: 10011266
    Abstract: A method for preventing over discharge of a battery includes steps of: detecting a gradient of a road on which a vehicle is running by a controller, when a battery is discharged under a state that an engine of the running vehicle is operated, detecting a clutch driving state of an engine clutch, which connects or disconnects the engine and an electric motor, after detecting the road gradient, detecting a SOC (State of Charge) of the battery after detecting the clutch driving state of the engine clutch, and carrying out a torque reserve control allowing more torque to be reserved in the engine, using a combination of the road gradient, the clutch driving state, and the battery SOC, such that the battery SOC is not lowered below a certain amount.

  • Patent number: 9991076
    Abstract: Electromechanical devices described herein may employ tunneling phenomena to function as low-voltage switches. Opposing electrodes may be separated by an elastically deformable layer which, in some cases, may be made up of a non-electrically conductive material. In some embodiments, the elastically deformable layer is substantially free of electrically conductive material. When a sufficient actuation voltage and/or force is applied, the electrodes are brought toward one another and, accordingly, the elastically deformable layer is compressed. Though, the elastically deformable layer prevents the electrodes from making direct contact with one another. Rather, when the electrodes are close enough to one another, a tunneling current arises therebetween. The elastically deformable layer may exhibit spring-like behavior such that, upon release of the actuation voltage and/or force, the separation distance between electrodes is restored.
