Filed:

Sep 28, 2001

Appl. No.:

09/967043

Inventors:

Robert E. Meier - Dallas TX
James D. Huffman - Richardson TX

Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

G02B 2600

US Classification:

359291, 359290

Abstract:

An improved DMD type spatial light modulator having an array of pixels ( ). The pixels ( ) are of the âhidden hingeâ design, each pixel having a mirror ( ) supported over a hinged yoke ( ). Addressing electrodes ( ) on an underlying metallization layer and addressing electrodes ( ) at the yoke level provide electrostatic forces that cause the mirrors to tilt and then to return to their flat state. The pixels ( ) are designed to provide increased clearance between the leading edge of the yoke ( ) and the underlying metallization layer when the mirrors ( ) are tilted. Various features of the improved pixel ( ) also improve the contrast ratio of images generated by the DMD.

International Classification:

H04Q 7/24
H04L 12/413

US Classification:

370338, 370445

Abstract:

Systems and methods for improving throughput in point-to-point wireless communication links are provided. In one particular implementation, a media access control (MAC) layer of the IEEE 802. 11 standard is enhanced for use in point-to-point links to take advantage of the limited number of nodes participating in the link. In one embodiment, a master/slave type protocol provides contention free operation between two wireless nodes. Multiple priority levels and voice traffic may be accommodated with guaranteed Quality of Service.

Cisco Technology, Inc. - San Jose CA

International Classification:

H04L 12/28

US Classification:

370256

Abstract:

In one embodiment, each network interface of a network device in a computer network may be classified as either a low-speed interface (e. g. , wireless) or a high-speed interface (e. g. , wired). Illustratively, then, low-speed interfaces may be configured (identified) as external interfaces to external links and high-speed interfaces may be configured (identified) as internal interfaces to internal links. By executing a multiple spanning tree (MST) protocol at the network device with other network devices in the computer network, network devices interconnected with internal links are in a same MST region and internal links within an MST region are preferred over external links between MST regions.

International Classification:

G06F007/00

US Classification:

707010000

Abstract:

A technique for network planning that includes an interface for guiding a network user through the network allocation process, such as defining groups of clients based on their capabilities. Portions of the wireless local area network infrastructure, e.g., access points, are allocated among the groups. When a client attempts to associate with an access point, the access point determines the client capabilities. If the client is supported by the access point, the access point allows the client to associate and sends the client a message that contains a prioritized list of other nearby access points allocated to service that client, otherwise the access point sends a prioritized roaming list of nearby access points to the client that are allocated to serve that type of client. Feedback is provided by the network infrastructure enabling a network user or the network to automatically reallocate resources based on the feedback.

International Classification:

H04Q 7/24

US Classification:

370338000, 726003000

Abstract:

A method for protecting a wireless network against spoofed MAC address attacks. A database is used for storing MAC address and user identity bindings. When a new request to access the network is received, the MAC address and user identity of the request is compared to the stored MAC address and user identity bindings. If a new request has an existing MAC address, but not the corresponding user identity, then the request will be denied. The bindings database contains the MAC Address, User identity bindings for wireless nodes and/or, for wired nodes. The MAC address, User identity bindings contained in the bindings database may be automatically learned or statically configured.

Inventors:

Robert E. Meier - Dallas TX

Richard L. Knipe - McKinney TX

Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

G02B 2600

US Classification:

359291

Abstract:

An improved micromechanical device comprising a substrate (104), a deflectable member (102) suspended over the substrate (104), at least one spring-ring (124) supported above the substrate (104); and at least one address electrode (110) spaced apart from substrate (104). The spring-ring (124) resists deflection of the deflectable member (102) when the deflectable member (102) deflects to contact the spring-ring (124). By moving the address electrode (110) off the substrate level, the micromirror is much more immune to particle-caused short circuits, and a planer surface on which to fabricate the mirror (102) is provided without the need to utilize an inverse spacer layer.
