Title: Subassembly electrical isolation connector for drill rod
Inventor: CAMWELL PAUL L
IPC: E21B47/12
Filed: 1998-03-16
Abstract: A subassembly electrical isolation connector for interconnecting adjacent tubular drill rods of a drilling system used in drilling bore holes in earth formations electrically isolates the inner connection of the drill rods.  The connector comprises a housing, a mandrel, a connector for connecting the housing to a first tubular drill rod, a connector for connecting a mandrel to a second tubular drill rod and a device for interconnecting the housing and the mandrel in a manner to electrically isolate the housing from the mandrel with the housing overlapping at least a portion of the mandrel. The housing has an isolated end which is electrically isolated from the mandrel and the connector for connecting the mandrel to a second tubular drill rod. The mandrel has a conical tapered body portion which is located within the housing and the housing has a corresponding conical tapered inner surface. The conical taper for the housing and the mandrel converge inwardly away from the housing isolated end. Such arrangement provides enhanced strength to resist bending moments along the connector and resisting drilling forces. The tapered surfaces provide for a connector retrieval in the event of connector break-up due to excessive drilling forces. The subassembly is particularly useful in applications involving directional drilling in earth formations, particularly oil well drilling, the drilling of bore holes under river beds and other obstacles and earth formations, bore hole inspection systems, directional drilling in respect of geothermal wells, ventilation shaft drilling in mineral mining formation and the like.

Patent CA-2250537-A1 (CA)
Inventor: DAHANAYAKE BANDULA
IPC: H04L25/02
Filed: 1998-10-23
Abstract: In transmitting information, Modulator-Demodulators (Modems) and digital communication systems in general employ adaptive equalizers in order to eliminate or minimize Inter Symbol Interference (ISI). Equalizers are indispensable part of a digital communication system. Adaptive equalizers used in practice require a training signal. To initialize Modems or digital communication systems, a signal that is known to the receiver has to be transmitted at the beginning.      In this invention, we introduce a new approach to eliminate the need for a training signal in initializing Modems or digital communication systems. We introduce a new, fast learning Adaptive Blind Equalizer that does not require a training signal. Hence, the Adaptive Blind equalizer is a self learning algorithm. The Adaptive Blind Equalizer can estimate channels and symbols irrespective of the phase properties of the channels. In other words, the Adaptive Blind Equalizer works with channels that are minimum phase, maximum phase, or mixed phase. This invention also includes a methodology for estimating the model order of a channel.      The learning characteristic of the Adaptive Blind Equalizer is independent of the signal to noise ratio (snr). The fast decaying characteristic of the learning curves indicates that the Adaptive Blind Equalizer learns fast. In the case of binary signals, the Adaptive Blind Equalizer learns in as few as twenty symbols. At higher signal to noise ratios, the variance of the channel parameter estimates of the Adaptive Blind Equalizer is negligibly small. In addition, the Adaptive Blind Equalizer achieves zero probability of error at high signal to noise ratios.

Patent CA-2270564-A1 (CA)
Inventor: HAYWARD C MICHAEL
IPC: H01R13/658
Filed: 1998-07-29
Abstract: In an improved connector assembly, a male pin (112) is inserted into a proximal end of a female contact which (110) conductively engages the pin at a distal end, providing a folded signal path geometry. As a signal propagates in a first direction along the male pin (112), it generates a first magnetic field of a first orientation about the male pin (112). At the contact point, the signal reverses direction and generates a second magnetic field of a second orientation opposite the first orientation about the female contact (110). Their respective opposed orientations cause the magnetic fields to substantially cancel in the region of magnetic interaction. Any remaining electric fields are contained by grounded shielding in the female contact (110) cavities. This configuration mitigates the effect of crosstalk between adjacent signals in the connector, and reduces the effective path length of the signal.
