  • Publication number: 20150184707
    Abstract: A disk brake device has a rotor, a carrier, a caliper, an inner pad, and a braking operation mechanism. The braking operation mechanism includes a base plate, a wedge plate, and a slide member movement mechanism which moves the wedge plate in a direction perpendicular to a braking surface while moving the wedge plate to slide in a rotating direction of the rotor. The carrier includes an inner-side rotating-direction movement restricting portion which faces the base plate in the rotating direction of the rotor and abuts against the base plate in the rotating direction of the rotor to restrict movement of the base plate in the rotating direction. The base plate is held by the caliper to be movable in the direction perpendicular to the braking surface with movement of the base plate in the rotating direction of the rotor kept restricted by the inner-side rotating-direction movement restricting portion.

  • Patent number: 8918873
    Abstract: The instant disclosure describes various exemplary systems and methods for exonerating an untrusted software component based solely on a trusted software component's non-optional or “hard” dependency on the untrusted software component. In one example, a method for exonerating untrusted software components in this manner may include: 1) identifying a dependent software component, 2) determining that the dependent software component is a non-optional dependent component of at least one trusted software component, and then 3) classifying the dependent software component as a trusted software component. As detailed herein, such a method may enable security software to quickly and efficiently exonerate untrusted components by association without having to scan or perform other intrusive and/or resource-intensive security operations on such untrusted software components.
