摘要:
An electro-optical storage system based on air-bearing-suspended optical head in a near-field configuration. The optical head effects a lens having front and rear focal planes. The head is spaced from an optical medium by a fraction of a wavelength. An imaging lens is positioned relative to the optical head so that the image of a beam steering element is at a focal plane of the optical head close to the imaging lens to form a telecentric system to minimize beam walk. More preferably, the imaging lens is positioned to deviate the image plane of the beam steering element away from the focal plane of the optical head by a desired spacing to form a pseudo telecentric system to minimize energy asymmetry in the reflected beam.

A method, non-transitory computer readable medium and application management computing device includes receiving at an application management computing device a request from a client computing device which requires authentication. A determination is made by the application management computing device whether user network identification information currently is stored for the requesting client computing device. The stored user network identification information for the authentication is obtained by the application management computing device when the user network identification information is determined to be currently stored for the requesting client computing device. The authentication is completed by the application management computing device with the obtained user network identification information.

A method for forming an array area with a surrounding periphery area, wherein a substrate is disposed under an etch layer, which is disposed under a patterned organic mask defining the array area and covers the entire periphery area is provided. The patterned organic mask is trimmed. An inorganic layer is deposited over the patterned organic mask where a thickness of the inorganic layer over the covered periphery area of the organic mask is greater than a thickness of the inorganic layer over the array area of the organic mask. The inorganic layer is etched back to expose the organic mask and form inorganic spacers in the array area, while leaving the organic mask in the periphery area unexposed. The organic mask exposed in the array area is stripped, while leaving the inorganic spacers in place and protecting the organic mask in the periphery area.

Described are a system and method for clustering wireless devices in a wireless network. The system comprises a wireless access point and a plurality of wireless computing units grouped into a cluster as a function of a predetermined parameter. The cluster includes a cluster head unit and at least one cluster member unit. The at least one cluster member unit utilizes a first power level when wirelessly communicating with the cluster head unit, and the cluster head unit utilizes a second power level when communicating with the AP.

Systems and methods consistent with the present invention enable routing table updates are performed by optimally utilizing the resources of a node without exceeding the resources of the node. Using feedback on the amount of resources available to the nodes, such as in terms of available memory, the node may make new connections before breaking old one where those updates will not exceed available resources. This is referred to as make-before-break. When not enough resources are available, the node will break old connections before making new ones. This is referred to as break-before-make. Unlike the strict make-before-break and break-before-make models, this “loose” make-before-break method considers the amount of available resources in view of the resources required to perform the routing table updates without a node failure. Routes may also be tagged to prioritize the addition of more important routes and the deletion of less significant routes. Methods and systems consistent with the present invention, therefore, provide a routing table update method with which routing table updates are achieved without crashing and at the same time minimizing black hole intervals.

Magneto-optical storage media designed for optical storage systems such as disk drives with optical flying heads. Dielectric layers are designed and implemented to maximize optical coupling between the flying optical head and the media and to reduce variations of signals with flight height of the flying optical head.

A deflection mirror tower (DMT) of a multiple-disk array, optical storage system includes a plurality of prism members, each having an angular mirror surface, arranged along a vertical axis of the DMT and configured at a predetermined angular orientation to deflect a laser beam to a respective disk surface. The DMT is generally fabricated using a two-level partitioning process. Several prepared glass substrates, i.e., one for each mirror type, are initially sliced into bars having predetermined geometries. A bar from each substrate is sequentially aligned to a master reference and bonded to adjacent bars to form an intermediate bar stack. The stack is then segmented into a plurality of DMT components, each having a plurality of prism members.

摘要:
A lens/mirror tower (LMT) of a multiple-disk array, optical storage system includes a plurality of lens and mirror elements integrally formed on a monolithic, optically-clear substrate. There is a specific lens/mirror set for each recording disk surface of the optical storage device; however, the mirror elements are preferably configured as one reflective surface of the substrate. The lenses are molded onto the opposite surface in a single operation that fixes their relative positions. The LMT is generally fabricated using a lens replication process. Initially, a glass substrate is formed with a trapezoidal configuration. A lens array mold is also formed with a plurality of cavities arranged in overlapping pairs. The cavities are filled with optical-quality resin and the mold is applied to the surface of the substrate opposing the reflective angular, e.g., 45.degree., surface. Once cured, the resin serves as an array of lenses that are aligned with the optical paths to the objective lenses of the disk array.
