Title: Channel state information reconstruction from sparse feedback data
Inventor: CHENG JUNG-FU
IPC: H04B7/04
Filed: 2010-04-23
Abstract: Accurate downlink channel estimates are calculated based on infrequently transmitted Channel State Information (CSI) feedback data from a UE 20. A plurality of non-uniformly spaced digital CSI feedback samples, representing the frequency response of a downlink communication channel, is received from the UE. The received CSI feedback samples are demodulated and inverse quantized. A time domain tap delay channel model is generated from the inverse quantized CSI feedback samples. The time domain tap delay channel model may be frequency-transformed to obtain a reconstructed frequency response of the downlink communication channel in the frequency domain. Alternatively, channel delays may be estimated based on prior delays and/or known references signals transmitted on the uplink. Channel estimates between CSI reporting instances may be predicted, such as by a sample & hold or a linear predictor. The delays may be presumed fixed, and Kalman filter coefficients evolved over time.

Title: Method for preparing a leavened, mechanically developed bread dough
Inventor: BERTOLAZZI ROBERTO
IPC: A21C1/00
Filed: 2010-05-10
Abstract: The present invention relates to a method of preparing a leavened bread dough, said method comprising the following sequence of processing steps: .cndot. combining flour, water, yeast and/or leavening agent, and optionally one or more additional bakery ingredients to produce a dough-type mix; .cndot. mixing and working the dough-type mix in a mixer to produce an underdeveloped dough with a density of 0.9-1.5 g/ml, the total energy input from the mixer into the underdeveloped dough during said mixing and working of the dough-type mix being at least 1 W.h/kg; .cndot.  further working a batch of at least 15 kg of the underdeveloped dough by subjecting it to deformation shear, thereby producing a developed dough; .cndot. dividing the developed dough into two or more developed dough pieces having an individual mass of 30-3000 g; and .cndot. leavening the developed dough pieces to yield leavened dough pieces having a specific volume of at least 2.0 ml/g; wherein the aforementioned sequence of processing steps is completed within 3 hours. The present process employs high energy working to produce an underdeveloped dough, followed by low energy working to further develop the dough. By employing a combination of high energy working and low energy working the total working energy needed for preparation of a fully developed dough can be reduced substantially. At the same time, this combination of working conditions produces a dough that after baking yields a very soft crumb with an extremely regular crumb structure. The invention further provides a loaf of tin bread having a unique cellular structure that can be obtained by the aforementioned method as well as an apparatus for operating the above mentioned method.
Patent CA-2763434-A1 (CA)
Title: Heat treatment of thin polymer films
Inventor: PLANETA MIROSLAV
IPC: C08J7/00
Filed: 2009-08-12
Abstract: Stretch film is treated by passing a web of tackifier-containing, unbloomed thin polymer film through a heater so that the web is heated to a temperature sufficient to cause tackifier bloom prior to the web reaching a next stage in an in-line process.  Also, a pattern can be applied to a thin polymer film. An oriented web of thin polymer film is passed across at least one heated roller having the pattern engraved thereon to define face regions and relief regions collectively conforming to the pattern. As the web contacts each roller surface, portions of the web positioned over the relief regions receive less heat than portions of the web positioned over the face regions, thereby causing the respective portions of the web to undergo differential, heat-induced shrinkage which imparts the pattern to the thin polymer film.

Title: Method for the treatment of wastewater containing ammonia
Inventor: NYHUIS GEERT
IPC: C02F3/34
Filed: 2009-08-07
Abstract: The invention relates to a method for treating wastewater (3) containing ammonia in a de-ammonifying activated sludge system. In said method, ammonia is first reacted to nitrite by means of aerobically oxidizing bacteria (AOB), whereupon ammonia and nitrite are reacted to elemental nitrogen by means of anaerobically oxidizing bacteria (AMOX), especially planctomycetes. Excess sludge obtained in said method is withdrawn and separated into a heavy phase primarily containing the bacteria (AMOX) anaerobically oxidizing ammonia and a light phase. The heavy phase is redirected into the system (1) or the tank (2) and/or is trapped and fed to another system, and the light phase is disposed of. The percentage of bacteria (AMOX) anaerobically oxidizing ammonia that amounts to less than 10 percent of the biomass in a single-sludge nitrogen elimination system in which excess sludge is not specifically withdrawn can be increased to more than 30 percent by means of the disclosed method. This allows the reaction volume of the tank (2) to be reduced accordingly and the process stability of the system (1) to be increased.

IPC: F25J3/06
Filed: 2012-05-11
Abstract: A method to recover olefins and C2+ fractions from refineries gas streams. The traditional recovery methods employed at refineries are absorption with solvents and cryogenic technology using compression and expansion aided by external refrigeration systems. In contrast to known methods, there is provided first a pre-cooling heat exchanger on a feed line feeding the gas stream to a in-line mixer, secondly by injecting and mixing a stream of LNG to condense the C2+ fractions upstream of the fractionator. The temperature of the gas stream entering the fractionator is monitored downstream of the in-line mixer. A  LNG stream is temperature controlled to flow through the injection inlet and mix with the feed gas at a temperature which results in the condensation of the C2+  fractions before entering the fractionator. A LNG reflux stream is temperature controlled to maintain fractionator overhead temperature. The fractionator bottoms temperature is controlled by a circulating reboiler stream.

Abstract: Systems and methods for authenticating users based on their gait. A sensor module with multiple sensors is placed inside a user' s shoe and biometric data is gathered from the sensors when the user takes a step. The data gathered from each of the sensors is then received by a data processing module. The data is processed and compared with a stored signature from an authenticated user. If the processed data does not match the stored signature within predetermined limits, then the user using the system is not authenticated. An alarm may then be generated. If, on the other hand, there is a match, the user is authenticated and this authenticated result can be used to give the user access to restricted resources.

Abstract: Skimmers, barges and related methods recover heavy oil or bitumen from contaminated water environments such as tailings ponds. The skimmer has an articulated mesh-like conveyor driven around a drum by a drive sprocket. A pusher mechanism discharges bitumen or heavy oil from cavities in the conveyor. In one embodiment, the skimmer includes an automatic depth control system. In other embodiments, knife--edged shear plates remove heavy oil or bitumen adhering to the conveyor and drum. A barge may incorporate multiple parallel skimmers. The barge may include a bitumen-transfer pump having an annular fluid-injection flange that generates an annulus of lubricating fluid inside a discharge hose. A  method of skimming heavy oil or bitumen involves using a skimmer that automatically adjusts its elevation or depth based on a control signal generated by a depth sensor.  Another method recovers and transfers bitumen by lubricating the discharge hose using the annular fluid-injection flange.

IPC: F16K5/20
Filed: 2012-10-16
Abstract: A self piloted check valve which utilizes closure of a piloting flapper valve to permit development of closure forces for a ball valve. The normally open ball valve has a central flow passage and simultaneously rotates and translates as it traverses between its fully open and fully closed positions. An opening bias system utilizes a combination of a first less stiff spring and a second stiffer spring. Reversible decoupling means disconnects and reconnects the second spring at a short travel distance from the normally open position of the ball, while the first spring always provides opening bias forces to the ball. The pressure induced force required to fully close the ball valve following decoupling of the second spring is more than the force required to overcome the combination of the first and second springs.
