Abstract:
Described herein are flexible implantable occluding devices that can, for example, navigate the tortuous vessels of the neurovasculature. The occluding devices can also conform to the shape of the tortuous vessels of the vasculature. In some embodiments, the occluding devices can direct blood flow within a vessel away from an aneurysm or limit blood flow to the aneurysm. Some embodiments describe methods and apparatus for adjusting, along a length of the device, the porosity of the occluding device. In some embodiments, the occluding devices allows adequate blood flow to be provided to adjacent structures such that those structures, whether they are branch vessels or oxygen-demanding tissues, are not deprived of the necessary blood flow.

Abstract:
Methods and apparatus are disclosed for erasing memory cells in a virtual ground memory core, wherein a row decoder apparatus employs a protective voltage to wordlines of a sector of cells while concurrently providing an erase voltage to selected wordlines of the same physical sector. Decoder circuitry and methods are disclosed for selecting a memory cell sector to be erased and adjacent sectors to be protected, which may be used in single bit and dual bit memory devices, and which enable column decoder circuitry to reduce the number of sector select circuits.

Abstract:
First topics related to a content page, such as a web page, are identified. Thereafter, second topics related to a first content element, such as advertisements, and a second content element, such as media files, are identified based on the first topics. Common topics are identified that are common to the first and second topics. Based on the common topics, first and second content elements are identified and combined in a bundle that is transmitted to a user requesting the content page.
Abstract:
A system providing three-dimensional visual navigation for a mobile unit includes a location calculation unit for calculating an instantaneous position of the mobile unit, a viewpoint control unit for determining a viewing frustum from the instantaneous position, a scenegraph manager in communication with at least one geo-database to obtain geographic object data associated with the viewing frustum and generating a scenegraph organizing the geographic object data, and a scenegraph renderer which graphically renders the scenegraph in real time. To enhance depiction, a method for blending images of different resolutions in the scenegraph reduces abrupt changes as the mobile unit moves relative to the depicted geographic objects. Data structures for storage and run-time access of information regarding the geographic object data permit on-demand loading of the data based on the viewing frustum and allow the navigational system to dynamically load, on-demand, only those objects that are visible to the user.
Abstract:
A system to provide automated services to heterogeneous devices in a network environment, which includes a device agent residing on each of the heterogeneous devices, a device communicator to register and synchronize the devices via each of the device agents, and a portal server to interface multiple content sources on behalf of the devices, wherein the devices communicate with the portal server via each of the device agents and the device communicator.
Abstract:
Disclosed are a method and/or a system for real-time analysis and marking of a target surface using a digital camera coupled marking device. In one embodiment, a master controller receives a real-time digital camera signal from the digital camera of a marking device communicatively coupled to the master controller. The master controller analyzes the digital camera signal using an image recognition algorithm, a machine vision algorithm, and a database and archives a visual state and an object design parameter of an object. The master controller compares the visual state of an object with a library of known visual states in the database to extract an associated marking pattern and a desired marking location of the object. The master controller generates and sends a marking command to a pin marker of the marking device. The pin marker engraves the marking pattern onto the object in real time.
