Title: End turn layout in an alternator stator assembly.
Inventor: NEET KIRK E
IPC: H02K3/12
Filed: 2003-12-22
Abstract: A slotted stator core assembly having straight slot winding portions and end loops (turns) with varying axial heights or extents, has layers comprising a first electrical conductor and a second continuous electrical conductor inserted circumferentially around the stator core, each layer being defined as one substantially complete circumferential pass of the conductors. The lengths of the straight portions and end loop portions vary between the layers based upon the radial location of the particular layer within the stator core and a pre-determined axial height of the end loop portions. The end loops may have varying apex angles so as to allow the axial extent of the loops to be that same or increase outwardly or inwardly. Alternatively axial variation may be produced by offsetting the layers. Improved cooling, ease of asembly and increased power density may be achieved by different configurations.

Filed: 2001-01-04
Abstract: CMOS integrated circuit devices include an electrically insulating layer and an unstrained silicon active layer on the electrically insulating layer. An insulated gate electrode is also provided on a surface of the unstrained silicon active layer. A Si1-xGex layer is also disposed between the electrically insulating layer and the unstrained silicon active layer. The Si1-xGex layer forms a first junction with the unstrained silicon active layer and has a graded concentration of Ge therein that decreases monotonically in a first direction extending from a peak level towards the surface of the unstrained silicon active layer. The peak Ge concentration level is greater than x=0.15 and the concentration of Ge in the Si1-xGex layer varies from the peak level to a level Less than about x=0.1 at the first junction. The concentration of Ge at the first junction may be abrupt. More preferably, the concentration of Ge in the Si1-xGex layer varies from the peak level where 0.2<x<0.4 to a level where x=0 at the first junction. The Si1-xGex layer also has a retrograded arsenic doping profile therein relative to the surface. This retrograded profile may result in the Si1-xGex layer having a greater concentration of first conductivity type dopants therein relative to the concentration of first conductivity type dopants in a channel region within the unstrained silicon active layer. The total amount of dopants in the channel region and underlying Si1-xGex layer can also be carefully controlled to achieve a desired threshold voltage.

Title: Blind modulation scheme detection using training sequences
Inventor: RAYNE MARK WENTWORTH
IPC: H04L1/00
Filed: 2004-10-28
Abstract: A receiver uses training sequences included in a transmission to determine the modulation scheme being used for the transmission by carrying out a correlation between the expected, known training sequence used for a given modulation type and the training sequence in the received signal, to see which training sequence produces the best correlation signal. The modulation scheme of the training sequence that produces the best correlation signal is the taken to be the modulation scheme being used for the transmission. The same method can also be used to detect a change in the modulation scheme used in a system which employs adaptive modulation. In a preferred embodiment training sequences with good auto correlation properties are selected to represent the different potential modulation schemes used. In a further embodiment, the receiver analyses the phase shifts (or amplitude or frequency shifts) present in the received signal to determine the modulation scheme used. In a further embodiment (claim 15) the use of a particular training sequence with a particular phase shift sequence for /8-D8PSK modulated transmissions is disclosed. In a further embodiment (claim 16) the use of a particular training sequence with a particular bit sequence for /8-D8PSK modulated transmissions is disclosed. In a further embodiment selection of a particular training sequence to use to represent a first modulation scheme (e.g. /8-D8PSK) is performed on the basis of the correlation properties of the training sequence with the first modulation scheme and with a second alternative modulation scheme (e.g. /4-DQPSK) that the system may use.

Title: Establishing network connections
Inventor: FRISKNEY ROBERT
IPC: H04L45/74
Filed: 2005-04-06
Abstract: The invention relates to enabling differential forwarding in address-based carrier networks such as Ethernet networks. There is described a method of and connection controller for establishing connections (76, 77) in a frame-based communications network comprising nodes (71-75 and 78) such as Ethernet switches. The connections are established by configuring, in various of the nodes, mappings for forwarding data frames, such as Ethernet frames. The mappings are from a combination of a) a destination (or source) address corresponding to a destination (or source) node (73) of the connection and b) an identifier, such as a VLAN tag. The mappings are to selected output ports of the various nodes. By using the combination of destination (or source) address AND identifier, the mappings enable data frames belonging to different connections (76, 77) to be forwarded differentially (ie forwarded on different output ports) at a node (75) despite the different connections having the same destination node. This enables flexibility in routing connections and the ability to perform traffic engineering.
