Patent CA-2355256-A1 (CA)
Inventor: GOOSEN ADRIAAN JOHANNES
IPC: C06C7/00
Filed: 1999-12-09
Abstract: This invention provides a detonation initiating device for a detonator, the device including two spaced electrical conductors; a resistive substance extending between the electrical conductors, for releasing energy upon application of an electrical current to the resistive substance; and an explosive composition including diazodinitrophenol (DDNP), covering the resistive substance. The explosive composition includes DDNP in fine particulate form as well as in a relatively larger particulate form. The detonation initiating device according to the invention, is not only very stable and resistant to accidental explosion, but also very reliable due to the presence of the fine particulate DDNP. Furthermore, the explosive composition of the detonation initiating device can be initiated even at the  low energy levels at which electronic initiating devices usually operate.</S DOAB>

Title: Electron beam multistage accelerator driven probe device
Inventor: DINSMORE MARK
IPC: G21K5/02
Filed: 1999-11-30
Abstract: A modular multistage accelerator (102) for use in an X-ray treatment system includes a first 10kV acceleration stage (150) which houses an electron beam  gun supplied with -50kV of voltage. The modular multi-stage accelerator includes four additional 10kV stages (112, 114, 116, 118) placed in series with the first stage to achieve a 50kV accelerator overall. Each stage is shielded (190) to prevent stray electrons from being propagated along the length of the drift tube. The triple point within each modular stage is recessed to significantly reduce the emission of stray electrons within each  stage. Additionally, the beam current at the X-ray emitting probe of the X-r ay source is measured by isolating the beam current to a beam current measuring  circuit (220) in electrical connection with a nulling junction node, wherein  other currents within the circuit are nulled at the nulling junction node an d the beam current flows to the beam current measuring circuit.

Title: Optical communications networks utilizing frequency division multiplexing
Inventor: UPHAM DAVID B
IPC: H04B10/2581
Filed: 2000-01-13
Abstract: A frenquency division multiplexing (FDM) node used in optical communications networks provides add-drop multiplexing (ADM) functionality between optical high-speed channels and electrical low-speed channels. The FDM node includes a high-speed system and an ADM crosspoint. The high-speed system converts between an optical high-speed channel and its constituent electrical low-speed channels through the use of frequency division multiplexing and preferably also QAM modulation. The ADM crosspoint couples incoming low-speed channels to outgoing low-speed channels, thus implementing the ADM functionality for the FDM node.

Abstract: A method and a wireless telecommunication system of performing network-assisted handover of calls between a serving network and another wireless network that employs communication protocols different from those of the serving network. A message is sent from a mobile station of a user to the serving wireless network, which includes an indication that the mobile station is capable of communicating with the neighboring wireless network. Information relating to the communication characteristics of the neighboring wireless network is also sent from the serving wireless network to the mobile station. Using the information relating to the communication characteristics of the neighboring wireless network, the mobile station receives radio signals from the neighboring wireless network. The quality of the radio signals between the mobile station and the neighboring wireless network is measured. The serving wireless network sends a message to the neighboring wireless network to request a handover of the communication transaction when the quality of the radio signals between the neighboring wireless network and the mobile station meets a predetermined minimum threshold. Then a handover of the communication transaction from the serving wireless network to the neighboring wireless network is executed after the neighboring wireless network has established a communication channel for the mobile station pursuant to the handover request.
