Patent CA-2528199-A1 (CA)
Inventor: MCNICOL JOHN D
IPC: H04J14/02
Filed: 2004-05-25
Abstract: A method of conveying a WDM optical signal through a WDM system includes demultiplexing the received WDM optical signal into two or more spectral bands. Each spectral band has a respective predetermined center frequency and bandwidth, which encompasses a respective portion of the transmission window of a communications link. Each spectral band is then independently conveyed through the WDM system. This arrangement provides a flexible banded MUX/DEMUX  architecture that enables multiple different channel plans (spectral grids) to co-exist within a common optical communications network. Legacy equipment can therefore continue in service, as traffic is gradually migrated onto new, higher capacity systems. This provides a convenient migration path for network service providers to progressively upgrade the information carrying capacity of network links, without stranding legacy equipment.

Abstract: A fixed phase power controller that converts a line voltage to an RMS load voltage includes an analog control block with a capacitor that receives an input that is independent of a change in magnitude of the line voltage and that charges and discharges to provide a trigger signal at a first frequency, a reset circuit that periodically resets an initial condition of the analog control block, a synchronization connection that provides a sync signal that synchronizes the trigger signal with a waveform of the line voltage, and a control circuit that clips a load voltage based on the synchronized trigger signal to define the RMS load voltage. The controller finds application in a lamp where it reduces the line voltage to an RMS load voltage suitable for a light emitting element.

Abstract: A method is provided for preparing luminescent semiconductor nanoparticles composed of a first component X, a second component A, and a third component B, wherein X, A, and B are different, by combining B with X and A in an amount such that the molar ratio B:(A+B) is in the range of approximately 0.001 to 0.20 and the molar ratio X:(A+B) is in the range of approximately 0.5:1.0 to 2:1. The characteristics of the thus-prepared nanoparticles can be substantially similar to those of nanoparticles containing only X and B while maintaining many useful properties characteristic of nanoparticles containing only X and A. The nanoparticles so prepared can additionally exhibit emergent properties such as a peak emission energy less than that characteristic of a particle composed of XA or XB alone; this method is particularly applicable to the preparation of stable, bright nanoparticles that emit in the red to infrared regions of the electromagnetic spectrum. Luminescent semiconductor nanoparticles having exemplary properties are also divided.

Title: Methods and apparatus for efficiently establishing and maintaining a data connection between a mobile station and a wireless network
Inventor: LIANG KENNETH J
IPC: H04W76/02
Filed: 2005-07-14
Abstract: A method for efficiently establishing a data connection, such as a Packet Data Protocol (PDP) Context, between a mobile station and a wireless communication network. The method includes transmitting a data connection request to the wireless network to attempt to establish a data connection between the mobile station and the wireless network; setting a delay timer to an initial value and running the delay timer. If the data connection has not been established in response to the data connection request, a subsequent data connection request is transmitted after expiration of the delay timer, and the delay timer is set to a subsequent initial value greater than the initial value. If the data connection has not been established in response to the subsequent data connection request, another subsequent data connection request is transmitted after expiration of the delay timer. This technique continues until the data connection is established with the wireless network, if at all.  If a new wireless network is selected during the process, the process is reset to the first initial value. Preferably, the technique works in combination with relatively quicker retries implemented in lower radio layer(s) (i.e. the physical, data link, or network layer). Thus, each data connection request may be a plurality of data connection retries which are performed closer together in time than other retry attempts.

Power control may be implemented per antenna basis or per sub-carrier basis. In performing power control, a subset of transmit antennas may be selected and waterpouring may be applied only to the selected antennas. Waterpouring may be based on SNR instead of channel response.

Inventor: MALHOTRA SANJIV
IPC: H01M8/24
Filed: 2004-09-20
Abstract: A compact direct methanol fuel cell (DMFC) system based on modules is provided. The system addresses issues related to the critical functions of water recovery from the cathode exhaust, carbon dioxide separation from the anode output stream, dilution of incoming concentrated methanol and thermal management in a DMFC system. The system is based on a more natural solution and avoids bulky and power-consuming devices; hence increasing DMFC system's efficiency by at least 25%, reducing DMFC system's cost and increasing DMFC  system's reliability compared to traditional condensor-based DMFC systems. In addition, the system is relatively small in size compared to these condensor-based DMFC systems mainly due to the use of modules based on plates that are nicely integrated as a DMFC system. The individual size of the system is typically reduced by about 35% or more compared to traditional condensor-based DMFC systems.

Filed: 2004-09-30
Abstract: Systems and methods for announcing and locating services that are shared in a distributed manner within a peer-to-peer packet-based network are provided by embodiments of the invention. As opposed to every network device of the network requiring a copy of every desired service, one or more network devices maintain a copy of a particular service and the service is shared by any network device in the network that requires the service. Available services at a particular network device are registered with that network device and then service availability is announced to all other network devices on the network.  Network devices maintain lists of what services are available on the network as well as where the services are located. When a particular service is desired, the network device consults the lists and is able to request acquisition of the service from any network device known to host the service, either locally or on a remote network device. Service location functionality is also capable of allocating resources and/or services in the network based on statistical information gathered and maintained regarding service use in the network.

Title: Communication apparatus, method and computer readable medium for adjusting the number of connection identification
Inventor: HSU HENG-IANG
IPC: H04L69/14
Filed: 2007-03-19
Abstract: A communication apparatus, a method, and a computer readable medium for adjusting the number of communication identifications (CID) are provided. The communication apparatus comprises a database, a quality of service (QoS) scheduler, and a CID  adjustment engine. The database stores first service information and second service information which respectively comprise a corresponding CID. The QoS scheduler determines whether an operating load thereof reaches to a threshold value. If yes, the CID adjustment engine unifies the CIDs of the first service information and the second service information. The QoS  scheduler schedules the first service information and the second service information in response to the unified CID.
