Title: Shifting phase of a clock signal, in particular for clock recovery of a digital data signal
Inventor: HEDBERG MATS
IPC: H03K5/13
Filed: 1992-11-25
Granted: 2002-03-05
Abstract: The invention relates to clock recovery for a digital data signal. A phase detector receives the data signal and transmits it after clock recovery. A phase correcting means creates and transmits, by means of a number of auxiliary clock signals phase shifted with respect to each other and originating from an incoming clock signal a recovered clock signal for the data signal. The recovered clock signal is fed to the phase detector, which detects a phase position error, if any, between the data signal and its recovered cloak signal and emits information regarding this to the phase correcting means. The phase correcting means includes a phase variation circuit arranged, if the phase position error deviates from zero and the phase position of the recovered clock signal is located between the phase positions of two of the auxiliary clock signals, to mix these two auxiliary clock signals with each other for forming an adjusted recovered clock signal with the same phase position as the data signal. The invention allows shifting of the phase of a clock signal continuously an arbitrary number of turns forwards or backwards without interruptions or discontinuities in the recovered clock signal. This implies that the invention can also be applied in the case of a difference occurring between the bit frequency of incoming data and the clock reference frequency.

Abstract: There disclosed a gas producing apparatus for producing a glass formation gas required in an FHD method, a VAD method or an OVD method. A glass formation material is supplied intact in the form of a liquid to a vaporizer, and the supply quantity of this liquid material is controlled directly by a liquid flow rate control means while the material is kept in the form of a liquid. In addition, at the same time the liquid material is vaporized by the vaporizer, a fixed amount supply means supplies an inert gas or a combustion gas at a fixed flow rate to the vaporizer. Since this prevents a pressure rise in the vaporizer, the liquid material is stably supplied to the vaporizer. Therefore, a fixed amount of vaporization of the liquid material is constantly performed in the vaporizer without being influenced by variations in the atmospheric pressure.      Furthermore, since the vaporized material is supplied to a burner together with the inert gas or the combustion gas supplied at a fixed flow rate from the fixed amount supply means, the burner injects a fixed amount of the material gas at any instant.

Abstract: A system for managing a telemarketing complex is disclosed  wherein  the  probability  of  meeting  a  given performance objective by the agents servicing an automatic call distributor (ACD) within the complex is computed for each subinterval of a predetermined service interval.  This probability is then compared with threshold levels in order to determine whether the ACD requires that calls be shifted to meet the performance objective or whether calls can be accepted by that ACD.   A record is maintained for each subinterval  of  the  probabilities  computed  for  that subinterval and as to whether the system succeeded or failed in achieving the performance objective at the end of the service  interval.   This record is used to compute  the threshold levels used in future comparisons.  In addition, the system computes a line-estimation factor which when multiplied by the number of agents working can be used to estimate the call load for an ACD.

Title: A process and apparatus for treating waste water
Inventor: DESJARDINS GAETAN
IPC: C02F3/28
Filed: 1995-09-15
Granted: 2009-07-21
Abstract: The process for treating waste water uses the combination of a septic tank operating in series with a biological reactor such as a sequencing batch reactor. In this process, waste water is supplied and accumulated in a septic tank. In the septic tank, the waste water and the settling sludge are biologically treated under anaerobic conditions. A given amount of treated waste water is then transferred from the septic tank into a biological reactor such as a sequencing batch reactor, where it is mixed and aerated. Such a mixing and aerating causes activation of the sludge and clarification of the waste water. The activated sludge in suspension in the liquor is then allowed to settle and an upper layer of clarified water formed above the mixed liquor after the settling period is decanted. The excess activated sludge in the biological reactor may then be removed therefrom and supplied into the septic tank so that the excess sludge be treated by digestion therein. The apparatus used to carry out the above-mentioned process comprises a septic tank provided with a baffle wall defining a first chamber where the sludge may settle and accumulate and where anaerobic fermentation is occurring, and a second treatment chamber where the solids are anaerobically digested. In operation, the waste water may flow from the first chamber to the second chamber by passing through the baffle wall. The apparatus also comprises a biological reactor for further treating the waste water under aerobic condition. A pump is provided for transferring the treated waste water in the septic tank to the biological reactor. This process allows a total treatment of waste water and all sludge for an extended period of time, from 5 to 15 years, without having to remove any byproducts for immediate treatment.

Abstract: A composite mini-extended nozzle is disclosed that is designed to both resist erosion and be strong enough to withstand the shock of a downhole drilling environment. In addition, means are provided to shroud at least a portion of the extended nozzle to further protect a portion of the nozzle nearest the exit plane from downhole obstructions. A combination of materials used to form the nozzle may include a matrix of tungsten carbides with suitable binder joined to an outer metal jacket nozzle body. A third ceramic matrix material may be utilized to line or partially line an interior passage formed by the mini-extended nozzle and a reduced in diameter portion of the nozzle design may include a built-in fracture plane in the unlikely event the end of the nozzle hits an obstruction. The extended portion of the nozzle will shear off along this fracture plane thereby preventing a nozzle washout that likely would result in a trip out of the hole to repair the resultant damage to the rock bit.

Title: Method of automatic database field identification for postal coding
Inventor: GARDNER DAVID P
IPC: G06F17/30
Filed: 1996-10-29
Granted: 2000-12-26
Abstract: The invention is a method of determining the contents of a selected data field.  The steps begin by attaching, from an application program, a database to be mapped.  Once the database is attached, a field identification module (FIM), will scan the contents of the database to determine a data field identifier for each of the data fields to be worked upon.  The FIM will then compare each of the data field identifiers with a list of known identifiers stored in a repository and assess a first score in respect of the comparison wherein the score is representative of a probability that the comparison is an accurate comparison.  When a first probability score has been determined, the FIM will sample the data field according to a pre-selected list of requirements and make a second comparison with the data field.  The FIM will then assess a second score.  After sampling and scoring the data field, the FIM will construct a test case wherein the data field is used in the postal coding or host application and a third comparison is made in respect of the test case.  The FIM will then assess a third score.  The FIM will choose a fieldtype based on the weighted average result of the three scores, and then request that the system operator confirm the selected field type.  Once confirmed, the data field identifier and the data field represented thereby are added to the repository as one of the known identifiers.

Title: Method and apparatus for post-processing images to reduce artifacts
Inventor: JAYANT NUGGEHALLY SAMPATH
IPC: H04N1/41
Filed: 1996-12-03
Granted: 2000-04-18
Abstract: The invention is an image transmitting method and system including receiving encoded images, decoding those images and post-processing the decoded images.  The post-processing reduces visual artifacts, such as blocking artifacts and mosquito noise, through separate detection, mapping and smoothing operations while avoiding many of the complexities associated with existing techniques. In detecting blocking artifacts, the inventive method employs DCT-domain detection rather than edge detection in the pixel domain. Also, the interior of a detected block is updated based on the surrounding blocks without disturbing the surrounding blocks. In reducing mosquito noise, the inventive method smoothes the non-edge pixels within blocks containing edge pixels rather than smoothing the edge pixels. Also, distortion-induced false edge pixels are distinguished from true edge pixels and heavily smoothed. The post-processing method and system is generally applicable to Block DCT based compression systems, either intrinsically or extrinsically.

Granted: 2001-02-13
Abstract: An elongated, pillow shaped prosthetic spinal disc nucleus body (10) for implantation into a human intervertebral spinal disc (32), made of a hydrogel core (12) and a flexible constraining jacket (14) surrounding the hydrogel material core (12) that permits the hydrogel core (12) to expand and contract. The hydrogel core (12) has a length approximating the sagittal diameter of a nucleus of the human disc, a width less than the length, and a height less than the length or width. The hydrogel core will expand (See fig. I) and contract in a desired fashion as it imbibes and expels fluids in response to various loads placed upon the spinal tract. The constraining jacket (14) is porous to allow fluids to pass through to the hydrogel core (12), but prevents the hydrogel (12) from escaping, thus fostering the natural physiology of the human invertebral disc. By implanting two prosthetic spinal disc nucleus bodies (10) side-by-side into a damaged disc (32) of a human spine, both height and motion can be maintained.
