Title: Communication system and method therein
Inventor: LINDBERG NICLAS
IPC: H04M7/00
Filed: 2000-12-22
Abstract: A communication system comprises user end points, a network, and an intermediate end point, the user end points being connected to the network via different link-layers. A session is invitated by a first user with a second user by means of an invitation signal from the first user over the network. The invitation is received by an intermediate point in the network, which allocates an invitation identity to the invitation. The intermediate point then forwards the invitation together with the invitation identity to the second user over the network. The second user receives the information about the invitation together with the invitation identity, and selects end point and/or access configuration for responding to the session invitation. The second user then responds to the request with the selected end point and/or access configuration by appending the invitation identity. The intermediate point associates the response with said invitation signal and establishes the session.

Title: A dual mode access point using different wireless LAN standards
Inventor: MORETON MICHAEL JOHN VIDION
IPC: H04L12/413
Filed: 2003-04-08
Abstract: A single multi-mode Access Point (AP, 110 fig. 2) supports both 802.11a and 802.11b Wireless Local Area Network (WLAN) standards simultaneously by use of Contention Free Periods (CFP), wherein the Carrier Sense Multiple Access Collision Avoidance (CSMA/CA) mechanism is suspended for a given time period while each station waits for a request ("poll") from the Access Point before transmitting a frame. Frames are not transmitted, unless a poll is received, if a network allocation vector (NAV) has a value above zero. Those frames not transmitted by the transceiver commanded to stay silent are stored in a queue for later retrieval. Access to both 2.4 GHz and 5 GHz band stations at the same time via two respective antennae (502, 504, fig.3) and two physical layers (405, 415) is thus provided without the need for separate Media Access Control (MAC) interfaces in the Access Point.

Title: Receiver for a quantum cryptography communication system
Inventor: YUAN ZHILIANG
IPC: H04B10/70
Filed: 2003-08-18
Abstract: In a quantum communications system a bright clock signal is transmitted to a receiver 303 in order to assist with the detection of encoded photons carrying bit values. It is believed that the intense clock pulses interact with the fibre 305 along which they pass generating unwanted photons at other wavelengths. To address this problem a band pass filter 325 is placed before the photon detector 329 in the receiver to block all photons except for the encoded photons. The filter may be placed after a divider 321 which separates the clock pulses and the encoded photons, and may be placed before the decoder 327 (e.g. an interferometer), or between the decoder and detector. In another embodiment, a polarising element is provided in the path of the encoded photons and is configured to pass only photons of a predetermined polarisation to the detector. Preferably the polarising element is placed between the decoder and detector. Application is to Quantum Key Distribution (QKD).

Title: Soft MIMO Demodulation using Sequential Monte Carlo Techniques in both Stochastic and Deterministic Settings
Inventor: WANG XIAODONG
IPC: H04B7/12
Filed: 2004-02-26
Abstract: A class of soft-input soft-output demodulation schemes for multiple-input multiple-output (MIMO) channels, based on to sequential Monte Carlo (SMC) framework under both stochastic and deterministic settings. The stochastic SMC sampler generates MIMO symbol samples based on importance sampling and resampling techniques, while the deterministic SMC approach recursively performs exploration and selection steps in a greedy manner. By exploiting the artificial sequential structure of the existing simple Bell Labs Layered Space Time (BLAST) detection method based on nulling and cancellation, the proposed algorithms achieve an error probability performance that is orders of magnitude better than the traditional BLAST detection schemes while maintaining a low computational complexity. Performance is comparable with that of the sphere decoding algorithm, with a much lower complexity. Both the stochastic and deterministic SMC detectors can be employed as the first-stage demodulator in an iterative or turbo receiver in coded MIMO systems.

Title: I.c. engine fuel system having pressure pulsation damping
Inventor: TREUSCH CHRISTOPHER JOHN
IPC: F02M69/46
Filed: 2004-07-30
Abstract: The invention relates to a fuel system 100 having pressure pulsation damping. The invention specifically locates restrictors 138 in relation to identified critical elements 134 of the system to control the maximum operating system pulse magnitude, as well as damping the overall pulsations of the system. A restrictor 138 is located at a distance D from an end of a critical element 134, resulting in less efficient damping than locating the restrictor within the critical element but useful when optimum restrictor location is not possible or practical because of packaging or other constraints. Compliance damping is also provided, whether by a dedicated compliance damper or by the inherent compliance of the fuel system.

Title: Controlling interference from a terminal at a base station during compressed mode
Inventor: BOOKER PHILIP
IPC: H04B7/005
Filed: 2004-11-12
Abstract: A method of controlling interference from a terminal at a base station (node B) comprises determining that the terminal has entered compressed mode and adapting the transmit power or data rate of the terminal such that interference at the base station stays below a predetermined level. In compressed mode, the time taken to transmit data is shortened in order to provide transmission gaps in which a terminal can make handover measurements. However, transmitting the data in a shorter time can increase the transmit power and cause interference peaks. In the invention, interference control may involve keeping the power or data rate below a maximum level set by the base station, having a reduced power or data rate set by the base station or having the network set a reduction in transmit power or data rate to be applied during the compressed mode.
