International Classification:

H04J 1400

US Classification:

359117, 343753, 370351, 370338, 370389, 370410

Abstract:

A wireless radio communication scheme in which data packets scheduled for transmission to spatially diverse locations are directed by a switched router apparatus capable of switching data packets and transmitting them between network nodes, where the direction and timing of switching is controlled in real time by the information derived from the packets route destination and the networks node spatial topology. The present invention uses a very high speed electronically controlled switched array feed for the microwave frequency range above 1 GHz, coupled to an RF focusing and collimating antenna that enables the wireless transceivers nodes to spatially switch data packets towards other wireless transceivers nodes based on the data packets routing, scheduling and link availability information.

International Classification:

H01Q 142

US Classification:

343872, 343874, 343876, 343911 L

Abstract:

An all-weather housing for outdoor microwave radio nodes arranged in a network, each node capable of directing or receiving a beam of microwave energy in a selected direction, the housing including a shroud enclosing a transceiver, antenna, switches, and utilities. Each shroud has a radome projecting from the shroud in line of sight relation to other radomes in the network. A microwave radio transceiver is disposed within the shroud, operating on a scheduled transmission and reception basis in accordance with a schedule provided in a control channel amidst data. A ball-shaped microwave refractive lens is located adjacent to the radome, inside of the shroud, with a curved array of feed ports and switches, with the feed ports communicating microwave energy between the transceiver and the radome through the lens in multiple selected directions.

International Classification:

H01L 2312

US Classification:

257704, 257678, 257783, 257710

Abstract:

In one embodiment, an integrated circuit packaging structure includes a first metal adhesion layer formed under a lid and a second metal adhesion layer formed over a substrate. The lid includes a free surface that may move a small amount without cracking. The second metal adhesion layer is configured such that its outer end does not extend past the free surface of the lid to minimize crack formation.

Assignee:

Silicon Light Machines Corporation - Sunnyvale CA

International Classification:

G02B 626

US Classification:

385 16, 385 14, 385 30

Abstract:

An optical switch comprises a substrate, first and second optical waveguide, and first and second conducting elements. The first optical waveguide is coupled to the substrate. The first conducting element is coupled to the first optical waveguide. The second optical waveguide is coupled to the substrate. The second conducting element is coupled to the second optical waveguide. In operation, a first electrical bias applied between the first and second conducting elements causes the first optical waveguide to not optically couple to the second optical waveguide. Further in operation, a second electric bias applied between the first and second conducting elements causes the first optical waveguide to optically couple to the second optical waveguide.

Abstract:

A join process is disclosed for a wireless mesh topology network. In the network, nodes have multiple spatial coverage sub-sectors together covering a larger sector angle and a node can establish connection with other nodes located in directions covered by its sub-sectors. The join process adds a joining node to the network and includes having the joining node listen to sub-sectors at a specific receiving frequency for a defined time. Thereafter, the network node changes its sub sectors and its receiving frequencies according to a defined timing and sequence. Active network nodes transmit organized invitation data packets on defined sectors, frequencies and timing, based on relative location and relative angle orientation deduced from sub-sectors already in use for existing internal network communication. This reduces frequency interference in the network and reduces time required for the join process.

International Classification:

H04B010/00

US Classification:

398135, 398136, 398139

Abstract:

A fiber optic transceiver capable of bi-directional communication comprises an incoming optical (downlink) signal, a detector comprising a detecting surface configured to detect a detected portion of the incoming optical signal that strikes the detecting surface, and a light modulator for modulating a reflected (uplink) signal. The reflected signal comprises a reflected portion of the incoming signal. The light modulator comprises a controllable reflection member for modulating the reflected signal, and a controller configured to control the controllable reflection member. The controllable reflection member implements micro-electro-mechanical systems (MEMS) technology wherein micro-reflective surfaces are physically positioned or oriented by the control signal, thereby affecting reflection and diffraction in such a way as to modulate the intensity of light entering an uplink channel.

US Classification:

438 48, 438778

Abstract:

In one embodiment, a method of treating a surface of a Micro-Electromechanical System (MEMS) device reduces or eliminates performance degradation due to charge migration and accumulation. Briefly, the method may include treating a dielectric surface of the MEMS device to replace hydroxyl groups with electrically neutral molecules, thereby converting the dielectric surface from a hydrophilic to a substantially hydrophobic nature. A MEMS device having a surface treated using the aforementioned method is also disclosed.
