摘要:
The present invention embodies an endovascular graft having an attachment frame connection mechanism that allows placement of the main body component in vasculature in combination with limb components. Various limb component-to-main body component attachment mechanisms are provided which ensure a reliable bond while facilitating a smaller delivery profile.

The present invention provides systems and methods for electronically-capturing a destination address of a package and for using the destination address to automate a package pre-load operation. An embodiment of the invention includes a compression system for compressing the destination address as a compressed MaxiCode symbol, a smart shipping label system for generating a shipping label with a compressed MaxiCode and a pre-load assist system for generating package handling instructions from the electronically-captured destination address.

A lock for a computer device comprises a lever operable to be positioned in a locked position and comprising at least one flange, a locking base slidably coupled to a device housing and attached to the lever, and a spring coupled to the locking base and to the device housing and operated upon by the lever, where in the locked position the at least one flange slides in a first corresponding at least one notch formed on the device housing, and where the locking base slides into a corresponding second notch formed on the device housing.

A missile has fins that rotate about a single axis to deploy from a stowed position to a deployed position. A foil longitudinal axis of each fin is angled relative to a shaft of the fin, such that a single-axis rotation of the shaft moves the foil from the stowed position to a deployed position. A coil spring may provide both torsion and compression forces to rotate the fin into the deployed position and lock it into place. Torsion rotates the shaft until it reaches a seat on a bushing that is around the shaft. Then compression forces from the spring engage a keyed protrusion on the shaft with a corresponding keyway in the bushing, locking the shaft in place. There may be an additional lock once the fin is deployed, such as a spring-loaded pin in the missile body that engages a depression in the shaft.

A variable wing section having an adjustable profile shape extending in the wing-span direction, includes a plurality of torsion boxes, which are positioned in the longitudinal direction, are torsionally stiff about the wing-span direction, and are each constituted of a first wing skin, a second wing skin opposite to it, and at least one spar. The variable wing section includes at least one vertebra, which has a transmission element that is connected to the first wing skin by a pendulum joint in order to compensate for a relative movement between the first wing skin and the at least one vertebra, and which has a vertically spaced-apart point of connection to a drive chord, the length of which may be changed, using a control command. The length of the drive chord is changed as a function of a control signal, and the at least one vertebra is rotated about the wing-span direction, so that the shape of the torsion boxes, and thus the profile shape, are changed in a predetermined manner.
