Abstract: The invention relates to a compound of formula (I), wherein R1 is C1-C8alkyl, phenyl or phenyl substituted by from 1 to 3 C1-C4alkyl or C1-C4alkoxy substituents; R2 and R3 are each independently of the other hydrogen or C1-C12alkyl; and Hal is F, Cl, Br or I. Compounds of formula (I) are valuable intermediates for compounds of formula (III) which are also a subject of this invention, wherein R1, R2, R3 and Hal are as defined above; R10 and R11 are identical or different and are C1-C12alkyl, C5-C12cycloalkyl, phenyl, C5-C12cycloalkyl substituted by C1-C4alkyl or by C1-C4alkoxy, or phenyl substituted by from one to three C1-C4alkyl, C1-C4alkoxy, -SiR4R5R6, halogen, -SO3M, -CO2M, -PO3M, -NR7R8, -[+NR7R8R9]X- or C1-C5fluoroalkyl substituents;  or the group -PR10R11 is a radical of formula (IV, IVa, IVb or IVc); R4, R5 and R6 are each independently of the others C1-C12alkyl or phenyl; R7 and R8 are H, C1-C12alkyl or phenyl or R7 and R8 together are tetramethylene, pentamethylene or 3-oxa-1,5-pentylene; R9 is H  or C1-C4alkyl; M is H or an alkali metal; X- is the anion of a monobasic acid. The compounds of formula (III) are themselves important intermediates for silylated ferrocenyldiphosphines and their metal complexes. Ferrocenyldiphosphines that contain an organic radical bonded via a silylene group to a cyclopentadienyl ring can be immobilised in a simple manner both on inorganic and on polymeric organic carriers or, after the introduction of a polymerisable group, can be immobilised also by copolymerisation. With rhodium and iridium the immobilised ferrocenyldiphosphine ligands form complexes that can be used as highly active catalysts in the enantioselective hydrogenation of carbon-carbon, carbon-nitrogen or carbon-oxygen double bonds.

Abstract: A telecommunication network establishes a telephone call from a first location that generates compressed voice packets to a second location.  The telecommunication network includes a plurality of switches, a first interworking function ("IWF") coupled to the first location and coupled to a first switch of the plurality of switches, a second IWF coupled to the second location and coupled to a second switch of the plurality of switches, and a network database coupled to said first switch.  When a telephone call is initiated from the first location, the first switch receives signaling information from the first location.  The first switch then queries the network database based on the signaling information and determines whether the second location uses compressed voice packets based on the query.  Finally, the first switch establishes a connection between the first IWF and the second IWF if it is determined that the second location uses compressed voice packets.  The connection bypasses the plurality of switches, and therefore reduces tandeming in the network.

Abstract: Diverse communication terminals attach via broadband radio to a communications network at any of typically three hierarchical cell sizes increasing from, typically, a single building to a city to a region.  Almost all telecommunications traffic transpires, however, within lowest-level "picocells 1" to and from low cost ''base stations 11" that have typically one radio transceiver (111), four optical transceivers (112), an ATM switch (113) and an ATM controller (114). Each local 'base station (11)" is interconnected to a regional "end office switch (12)", where is realized connection to a worldwide wire/fiber line communications backbone (4), upon a multi-hop mesh network (100) via short highly-focused free-sace broadband directional optical links (10).  By this free-space wireless broadband access the need for new broadband access cabling the "last mile" to subscriber/users is totally surmounted. Subscriber service is of the order of 20 Mb/s peak rate, and 10 Mb/s average rate.

Title: A linear amplifier arrangement
Inventor: MCNICOL JOHN D
IPC: H03G5/16
Filed: 1999-12-07
Granted: 2006-11-14
Abstract: This invention relates to high power linear amplifiers. A high power linear amplifier is disclosed for communications such as CDMA communication systems. In accordance with the invention, there is provided a linear power amplifier comprising a power amplifier, a feedback circuit and a control element; wherein the architecture proposed uses an envelope detector to generate a baseband signal representing the amplitude envelope of the system input RF signal. This is digitised and used to generate phase and gain correction signals. The correction signals modulate the input signal to create a pre-distorted signal: which is applied to the power amplifier for amplification. The pre-distortion is such as to cancel the AM-AM and AM-PM distortion of the power amplifier thus resulting in an amplified output of improved spectral purity. In order to achieve the very high levels of spectral purity required by 3G cellular and multi-carrier 2G cellular systems, the correction coefficients in the lookup table need to be very precisely set. The method proposed incorporates an adaptation system whereby the pre-distorter can 'learn' the contents of the lookup table as it operates.
