Abstract: An apparatus is formed from a double active layer silicon on insulator (DSOI) substrate that includes first and second active layers separated by an insulating layer. An electrostatic comb drive is formed from the substrate to include a first comb formed from the first active layer and a second comb formed from the second active layer. The comb drive may be used to impart a tilting motion to a micro-mirror. The method of manufacturing provides comb teeth exhibiting an aspect ratio greater than 1:20, with an offset distance between comb teeth of the first and second combs that is less than about 6 ?m.

Abstract: Methods and corresponding systems for spectrum management featuring advanced frequency-allocation planning and advanced interference avoidance. The invention discloses access points that transmit directionally and assigning a predefined channel in a predefined direction, in order to reduce interference between closely located access-points.

Abstract: A MOEMS apparatus for scanning an optical beam is formed from a double active layer silicon on insulator (DSOI) substrate that includes two active layers separated by an insulating layer. The apparatus includes an electro-static comb drive having a stator formed in a first of the two active layers and a rotor formed in a second of the two active layers. The electro-static comb drive is operative to impart a tilting motion to a micro-mirror formed in the second active layer. The MOEMS apparatus is designed such that: a) at least one of the distances created between a tooth belonging to the rotor and an adjacent tooth belonging to the stator is less than 7 ?m; and the aspect ratio of the apparatus is higher than 1:20.

Abstract: The invention relates to a device to be used in a wireless communication system with CSMA-based MAC, comprising transmitting circuitry for transmitting at least a first and a second RTS message and at least a first and a second data packet on a transmission medium, and a spatially selective antenna. It is further proposed that the device uses a distributed antenna that combines the antenna elements of several devices and that the device observes the transmissions of other devices, analyzes the observed transmissions for transmission patterns and adapts its own transmissions to the detected transmission patterns. The invention further relates to a system, a method and a computer program to be used in a wireless communication system.
