Patent CA-2236954-C (CA)
Title: Data detector and method using the same
Inventor: JEON JIN-KYU
IPC: H03M13/41
Filed: 1998-05-06
Granted: 2002-07-16
Abstract: A data detector and a data detection method. The data detector includes: a converter for converting a received signal into digital data according to a sampling clock signal; a maximum likelihood decoder for performing maximum likelihood decoding of the digital data; and a generator for measuring a phase difference between sampling points of the digital data and optimal detection points of the received signal, and for generating a control signal for changing the phase of the sampling clock signal according to the measured phase difference. The phase of the sampling points as the data detection points matches that of the optimal detection points, so that error caused by difference in phase is minimized, thereby enhancing the performance of the maximum likelihood decoder, and the overall performance in detection of reproduced data.

Abstract: A closure for a container and a method of producing the same is set forth. The closure is a single integrally-molded spout, cap and hinge assembly joining the spout and the cap. The closure may also have a membrane and pull-ring, also integrally molded as one piece. The cap may have at least one prop for preventing interference from the cap with the pouring of the contents of the container. Additionally the spout may have a step for assisting in the prevention of interference from the cap during pouring, and for providing a predetermined sound every time that the cap is opened. Further, the closure may have a tamper-evident member to indicate that the closure has been opened. Still further, the closure may have an orienting peg for properly orienting the closure on a container.

Abstract: A sprue bar assembly for a melt transfer system for stack molds comprises a sprue bar and a sprue bar sleeve, a sprue bar and drool restrictor and sleeve or a sprue bar and drool restrictor.   For the assemblies with the sleeve, when the stack mold is opened, the sprue bar slides inside the sprue bar sleeve which captures any leakage therefrom. When the mold is closed, the sprue bar sweeps captured leakage out of the sleeve to an area outside the mold. As the bushing at the end of the sprue bar can contact the nozzle of the injection machine at a point very close to the edge of the fixed platen, the resulting minimum length of the sprue bar is reduced, reducing pressure losses through the sprue bar and reducing the cost of the sprue bar. The sprue bar sleeve can be fabricated from an insulating material to enhance the thermal characteristics of the sprue bar assembly and a scraper can be provided on the sprue bar to improve removal of captured material from the sprue bar sleeve. If a drool restrictor is provided within the bushing, the amount of drool from the sprue bar when the bushing is not in engagement with the nozzle of the injection machine can also be reduced and, in some circumstances, can eliminate the need for the sleeve.

Abstract: A flush toilet for a recreational vehicle has a flush mechanism including a pair of foot pedals, one for opening the bowl outlet closure of the toilet, and the other for opening the flush water valve. Depression of the first foot pedal also depresses the water valve foot pedal, though that pedal can also be operated separately. An actuating cable for the water valve extends through the arm of the bowl closure foot pedal so that, if the water valve foot pedal breaks or is damaged, the water valve can still be opened for rinsing the bowl.

Title: Method and apparatus for mud pulse telemetry in underbalanced drilling systems
Inventor: HARRELL JOHN
IPC: E21B47/18
Filed: 1999-01-18
Granted: 2006-12-05
Abstract: A mud pulse telemetry system uses a downhole pulser to produce sequences of positive and/or negative pulses according to a selected pattern. Positive pulses, negative pulses, and combinations thereof may be produced. A flow rate sensor at the surface measures changes in the flow rate at the top of the wellbore instead of or in addition to changes in the pressure. The flow rate changes are detectable even though the pressure pulses themselves may have a poor signal to noise ratio. This enables the invention to function effectively in underbalanced drilling wherein the use of light muds with a high gas content is required. One embodiment of the invention uses a conventional downhole pulser with the main valve closed and the pilot valve operating in a direct pulse mode.

Abstract: A Time-Of-Flight mass analyzer includes a multipole ion guide (16) located in the ion flight path between the ion source (1) and the flight tube (42) of the Time-Of-Flight mass analyzer.  In one preferred embodiment, a Time-Of-Flight (TOF) mass analyzer is configured such that a multipole ion guide is positioned in the ion path between the ion source and the ion pulsing region (30) of the TOF mass analyzer.  The multiple ion guide electronics and the ion guide entrance and exit electrostatic lenses (26, 27 and 28) are configured to enable the trapping or passing through of ions delivered from an atmospheric pressure ion source. The ion guide electronics can be set to select the mass to charge (m/z) range of ions which can be successfully transmitted or trapped in the ion guide. All or a portion of the ions with stable ion guide trajectories in transmission or trapping mode can then undergo Collisional Induced Dissociation (CID) using one of at least three techniques.  The multipole ion guide is used for ion transmission, trapping and fragmentation can reside in one vacuum pumping stage (138) or can extend continuously into more than one vacuum pumping stage (18, 19).

Abstract: A high-capacity optical fiber network [100, 200] includes wavelength-division multiplexing (WDM) within the 1.4 micron (µm) wavelength region (i.e., 1335-nm). Such a system includes optical fiber [130] whose peak loss in the 1.4 µm region is less than its loss at 1310 nm. The optical fiber has a zero dispersion wavelength (.lambda.0) at about 1310 nm, and linear dispersion between about 1.5 and 8.0 ps/nm-km within the 1.4 µm region. At least three WDM channels operate at 10 Gb/s in the 1.4 µm wavelength region and have a channel separation of 100 GHz. In one illustrative embodiment of the invention, a broadcast television channel, having amplitude modulated vestigial sideband modulation, simultaneously operates in the 1.3 µm region (i.e., 1285-1335 nm) and/or the 1.55 µm region (i.e., 1500-1600 nm).  In another embodiment of the invention, 16 digital data channels are multiplexed together in the 1.55 µm region, each channel operating at about 2.5 Gb/s.  Raman amplifiers [103, 113] are used for amplification in the 1.3 µm and the 1.4 µm wavelength regions, whereas an Erbium amplifier [123] is used for amplification in the 1.55 µm wavelength region.
