Patent CA-2446115-A1 (CA)
Inventor: CAMERON JOHN ALASDAIR MACDONAL
IPC: E21B17/02
Filed: 2002-09-24
Abstract: The present invention provides a recess (10) within an expandable downhole tubular (20), such as an expandable sand screen. The recess resides within the wall, such as the outer shroud (26) of an expandable sand screen (20). The recess serves as a housing for instrumentation lines, fibre optics, control lines, or downhole instrumentation (62). By placing the lines and instrumentation within a wall of the expandable downhole tool, the tool can be expanded into the wall of a wellbore (48) without leaving a channel outside of the tool through which formation fluids might vertically migrate. The recess is useful in both cased hole and open hole completions. In one embodiment, the recess serves as a housing for an encapsulation (10') which itself may house instrumentation lines, control lines, and downhole instrumentation.

Abstract: A packet data service node (202) is formed to establish an "always on"  connection with a mobile terminal (210,212) by way of a packet control function card (206B-C) or device with the ability to determine when a mobile terminal (210,212) no longer requires a previously established point-to-point protocol communication link. More specifically, the PDSN formed according to one embodiment of the present invention, includes an inactivity timer and corresponding logic to prompt it to generate an LCP Echo Request (326-330) to the mobile terminal after expiration of the inactivity timer. Each time data or control signals are received from the mobile terminal, the inactivity timer is reset. In one embodiment of the invention, the LCP Echo Request (326-330) is generated at least once and a total of three times prior to the release of network resources responsive to not receiving an LCP Echo Reply from the mobile terminal. Logic defined by the PDSN and its corresponding method of operation facilities the release of resources being wasted by a mobile terminal that no longer needs resources.

IPC: C01B3/00
Filed: 2002-08-16
Abstract: An intense ultraviolet radiation source is disclosed that may be operated in substantially any arbitrary gas environment, without regard to a containment envelope for the ultraviolet radiation source. The intense ultraviolet radiation source can be generated by applying a pulsed or continuous electrical discharge to a partially ionized combustion flame via two electrodes. The combustion flame and electrical discharge can be focused, contained, or confined by gas pressure, electric fields, and/or magnetic fields. Optionally, the thermal energy in the flame and the electrical discharge power input may be augmented with an electromagnetic radiation source, such as a radio-frequency induction heater, a laser, or a microwave generator. Impurities may be placed in contact with or added to the fuel and/or the oxidizer to further alter the emitted ultraviolet radiation spectral brightness as needed. The ultraviolet source may be applied to the molecular dissociation of pollutants in exhaust gas streams of combustion systems. The efficient dissociation of such pollutants requires UV in the wavelength ranges of the vacuum ultraviolet band (100 nm - 180 nm) and the UV-C band (180 nm - 280 nm).

Filed: 2003-03-28
Abstract: Power circuit for starting and operating a gas discharge lamp. An input dc-voltage, usually obtained from an AC-mains voltage through a pre-connected rectifier and Power Factor Corrector, is converted by a series connection of two power transistors to an ac-voltage, which, via an LC section is presented to a gas discharge lamp. For starting the lamp, the power transistors are switched with a frequency which is slightly higher than approximately one-third or one-fifth of the resonance frequency of the LC section. Circuits have been provided for limiting the output voltage, for limiting the lamp current and for stabilizing the lamp output. Safety circuits switch the power circuit off if the lamp does not ignite or if the lamp exhibits rectifying effect.

For data transmitted with a spreading factor other than the uniform spreading factor, the estimated symbols of that data is converted to symbols of the code of that data. Another aspect of the invention receives a spread spectrum communication signal having data spread using a plurality of spreading factors. The data of the communication is estimated as estimated symbols using codes of a uniform spreading factor. The estimated symbols are parsed into parcels, where the estimated symbols correspond to data transmitted with a same spreading factor. For parcels not of the uniform spreading factor, the estimated symbols are converted into symbols of the same spreading factor of that parcel.
