Title: A self-aligning patterning method for use in the manufacture of a plurality of thin film transistors
Inventor: LI SHUNPU
IPC: H01L21/336
Filed: 2004-12-09
Abstract: The method comprises firstly forming a patterned mask 20 on the surface of a sacrificial layer 18 which is part of a multi-layer structure 10 which comprises a substrate 12, a conductive layer 14, an insulating layer 16 and the sacrificial layer 18. Unpatterned areas are then etched to remove the corresponding areas of the sacrificial layer, the insulating layer 16 and the conductive layer 14 thereby leaving voids. A layer of dielectric 22 is then deposited over the etched multi-layer structure to at least substantially fill the voids. The deposited dielectric is then etched in order to at least partially expose the sides of the remaining areas (28) of the sacrificial layer. Conductive material (30) is then deposited on the surface of the etched dielectric. Finally, the remaining areas (28) of the sacrificial layer are removed together with any overlying material leaving parts of the conductive material to form drain and source electrodes 32, 34. A layer of semiconductor material 36 is then added. The resulting plurality of multi-layer thin film transistors is preferably in the form of an array which may in turn be formed into a display device by coupling each transistor in the array to a light-emitting cell, e.g an organic LED. The method is suitable for use in a roll-to-roll fabrication method using a flexible substrate. Instead of forming bottom-gate transistors, or an alternative embodiment is used to make top-gate transistors.

Title: Simulating a hard disk
Inventor: CHANG AN-SHENG
IPC: G06F12/08
Filed: 2005-09-19
Abstract: A device and a method for simulating a hard disk are disclosed. The device has a core logic chip, a main memory module and a setting module. The setting module is used to set the main memory module to have a memory access area and a hard disk access area. The core logic chip has a memory controller and a conversion interface controller for controlling data reading of the memory access area and the hard disk access area, respectively. When the core logic chip receives a read/write signal sent to the main memory module from a computer system, it determines whether this read/write signal is a memory read/write signal or a hard disk read/write signal. If the read/write signal is for memory, it is sent to the memory controller; if the read/write signal is for hard disk, it is sent to the conversion interface controller.

Title: Multiuser transmitted-reference UWB communications system
Inventor: WITRISAL KLAUS
IPC: H04B1/69
Filed: 2005-10-27
Abstract: An impulse radio (IR) ultra-wideband (UWB) communication system supports multiple users by combining transmitted reference (TR) data coding with three spread spectrum codes: an amplitude spreading code (12, fig. 1), a delay hopping (DH) code (13, fig. 1) and time hopping (TH) code applied by a timing generator (14, fig. 1). The spreading code (33) and delay hopping code (32) reduces narrowband interference, and pulse bursts (34) and idle times (35) are time hopped (36) to avoid collisions (37) with pulse bursts from other transmitters. The receiver (fig. 2) then "tunes" to the desired signal by synchronising (25a, fig. 4) to the three codes by correlation of the received signal with the known code sequences, and applies Forward Error Correction (FEC).
Patent GB-2419755-A (GB)
Title: Correcting sampling errors
Inventor: MOORE GEORGE S
IPC: H03M1/66
Filed: 2005-10-28
Abstract: Scaling factors and delay values associated with respective analog-to-digital converters (ADCs) of an interleaved ADC 100 are stored in memory and, as a digital sample from the interleaved ADC is received, a respective amplitude scaling factor A is retrieved from memory and applied to the digital sample 151. A first order correction is then applied to the amplitude corrected-sample. The first order correction estimates the derivative 153 using the current amplitude corrected sample and at least one additional amplitude corrected sample. The derivative is multiplied 154 by an estimate of the respective timing delay associated with the particular sample. The corrected amplitude value is added 157 to the multiple of the derivative and the timing delay to form the fully corrected digital sample. The input to a digital to analog converter may be corrected in a similar way.

Title: Mobility management of mobile nodes in IP networks
Inventor: CHEN XIAOBAO X
IPC: H04L29/06
Filed: 2006-01-18
Abstract: A telecommunications system is arranged to provide a mobile communications session to a mobile node using an internet protocol. The telecommunications system comprises a home packet data network which includes a home agent of the mobile node and a visited packet data network. One of the home packet data network or the visited packet data network includes a packet data gateway for controlling the communication of the internet packets to and from the home packet data network from and to the visited packet data network. The mobile node is arranged to communicate a correspondent node binding update internet packet to the correspondent node via the packet date gateway, when the mobile node changes affiliation from the home packet data network to the visited packet data network. The correspondent node binding update internet packet provides a care of address of the mobile node within the visited packet data network and a home address of the mobile node. The packet data network is arranged to store the home address of the mobile node in association with the care of address of the mobile node, to adapt the correspondent node binding update internet packet by replacing the care of address in the received correspondent binding update packet with the address of the packet data gateway, and to communicate the adapted correspondent binding update packet to the correspondent node. The correspondent node therefore receives a correspondent binding update with the packet data gateway as the care of address. Thus, when the correspondent node communicates with the mobile node using the care of address of the packet data gateway, the packet data gateway can adapt the received internet packets, replacing the packet data gateway's address as the destination address with the care of address of the mobile node. Therefore, although a route optimisation process has taken place the internet packets are still routed via the packet data gateway.
