20120269307 | PROCESSING A RADIO FREQUENCY SIGNAL - Circuitry and a method for use in a radio frequency receiver for processing a radio frequency signal are provided. The circuitry comprises a mixer arranged to receive the radio frequency signal and down-convert the received radio frequency signal to a lower frequency. The received radio frequency signal has an interference component and the interference component in the down-converted signal is within an interference frequency range. The circuitry also comprises an LC based notch filter arranged to receive the down-converted signal from the mixer, filter the down-converted signal, and output the filtered signal for processing by a baseband processing block. The LC based notch filter has a notch centered within said interference frequency range, such that the LC based notch filter is arranged to attenuate the interference component in the down-converted signal. | 10-25-2012 |

20090216376 | Group Elevator Scheduling With Advanced Traffic Information - A near-optimal scheduling method for a group of elevators uses advanced traffic information. More particularly, advanced traffic information is used to define a snapshot problem in which the objective is to improve performance for customers. To solve the snapshot problem, the objective function is transformed into a form to facilitate the decomposition of the problem into individual car subproblems. The subproblems are independently solved using a two-level formulation, with passenger to car assignment at the higher level, and the dispatching of individual cars at the lower level. Near-optimal passenger selection and individual car routing are obtained. The individual cars are then coordinated through an iterative process to arrive at a group control solution that achieves a near-optimal result for passengers. | 08-27-2009 |

20100024750 | Apparatus to improve the efficiency of internal combustion engines, and method thereof - Method and apparatus for controlling the volume of air or air and non-combusted fuel mixture inside a combustion chamber and cylinder of an internal combustion engine. The apparatus includes an inlet-outlet portal having open and closed states and connected to air or air and non-combusted fuel source(s), and a combustion chamber with reduced volume. The inlet-outlet portal is controlled, when open, to permit air or air and non-combusted fuel mixture to enter or enter and exit the combustion chamber and cylinder and when closed to prevent air or air and non-combusted fuel mixture from entering or exiting the chamber and cylinder, in which the volume of air or air and non-combusted fuel mixture located inside the chamber and cylinder when the inlet-outlet portal closes, is less than the volume of the combustion chamber and cylinder defined when the piston is at the bottom dead centre position inside the cylinder when the inlet-outlet portal is closed. | 02-04-2010 |

20140220228 | EXTRACTION OF PHYTOCHEMICALS AND IMPROVED ANIMAL FEED - Disclosed are methods and systems for a first stage of fractionating a lignocellulosic material or lignocellulosic-containing biomass to extract phytochemicals and low molecular weight lignins and lignans, collectively identified as extractives, by treating lignocellulosic material or biomass with an alkali in an exemplary alcohol/water co-solvent system. The extractives are species specific and can later be separated and isolated individually. The system has the added advantage that it renders the residual polymeric biomass, sometimes referred to as bagasse, as an enhanced digestibility animal feed or more accessible for enzymatic or chemical modification. The extractives separated in the methods of the invention are in a form closer to their native state than any form that can be obtained from other biomass pretreatment processes. | 08-07-2014 |
