  • Patent number: 8352727
    Abstract: A basic idea of this system is to separate ordered delivery data and unordered delivery data in a security protocol running on top of a reliable transport protocol, and perform a first type of security processing for ordered delivery data and a second different type of security processing for unordered delivery data in the security protocol. Preferably, data messages using ordered delivery and data messages using unordered delivery within a secure data stream are separated into two message sequence spaces on the security protocol layer, and data security processing is then performed differently in these two spaces. This system is particularly suitable for a reliable transport protocol such as SCTP (Stream Control Transmission Protocol). The security protocol running on top of the transport protocol is preferably based on the TLS (Transport Layer Security) or a TLS-like protocol with a security processing extension for unordered delivery.

  • Patent number: 8310827
    Abstract: A strap mechanism for drawing an electronic device from a cage in a first direction is disclosed. The strap mechanism includes a first rail. The first rail includes a first locking part for connecting with a lateral surface of the electronic device and disposed inside the cage in a slidable manner, and a first handle part connected to an end of the first locking part. A first slot is formed on the first handle part. The strap mechanism further includes a strap. A first end of the elastic strap is inserted inside the first slot. The strap is for contacting against the first handle part so as to provide a component force in the first direction and in a second direction perpendicular to the first direction to the first handle part when a deformation of the elastic strap is generated by being pulled in the first direction.

  • Patent number: 8308113
    Abstract: A panel positioning mechanism includes a supporting component, and a slot is formed on a side of the supporting component. The panel positioning mechanism further includes a loading component disposed on a side of the supporting component, a rotational spring set connected to the supporting component and the loading component, a fixing component set for fixing the supporting component, the loading component, and the rotational spring set, a contacting component connected to the loading component and disposed inside the slot in a slidable manner so as to constrain rotation of the loading component within a first range, and a releasing component passing through the loading component and fixed on the contacting component for driving a contacting portion of the contacting component to separate from the slot on the supporting component, so that the loading component can rotate outside the first range.

  • Patent number: 8159817
    Abstract: A hard disk device includes a hard disk having two opposite first sides, a second side interconnecting the first sides, and two corner portions defined by the first and second sides, and a slide rail mechanism including two first plates to be disposed slidably in a housing, and a second plate. Each first plate has a first section connected to the second plate, and a second section connected to the first section. The first section is spaced apart from the respective first side and is provided with a first support element for abutting against the corresponding corner portion. The second section abuts against the corresponding first side and is provided with positioning pins for engaging positioning holes in the corresponding first side. The second plate is spaced apart from the second side and is provided with second support elements for abutting against the second side.

  • Patent number: 8159816
    Abstract: A computer component securing device includes a rack and a pair of rail assemblies. The rail assemblies are mounted respectively on two sides of a computer component and are disposed on the rack. Each rail assembly includes a rail and a handle pivoted to a front end of the rail. The handle is disposed to facilitate manipulation by a user. By turning the handle pivotally relative to the rail about an angle, a portion of the rail is urged in a direction away from the computer component to interferingly engage the rack so as to position the computer component in the rack.

  • Patent number: 8040669
    Abstract: An adjustable shifting structure is disclosed. The adjustable shifting structure comprises a base bracket, a movable bracket, a fixture element, and an adjustment element. The movable bracket is movably connected to the base bracket. The fixture element is disposed on the base bracket. The movable bracket is gripped by the fixture element and the base bracket to limit the moving direction of the movable bracket. The adjustment element extends through the base bracket, the movable bracket and the fixture element. The movable bracket may be moved by adjusting the adjustment element to apply force on the fixture element.
