| 20090232686 | Integrated Catalyst - The invention relates to an air compressor having a catalyst that is disposed in a reception block. The reception block is interposed between a valve block and a cylinder cover, comprises an inlet port in the region of a valve block outlet port, and an outlet port in the region of a cylinder head inlet port, so the compressed air exiting the valve block outlet port flows through said catalyst and through the outlet port into the cylinder cover. | 09-17-2009 |

| 20100327488 | Method of Making Hollow Concrete Elements - A method of making an open ended hollow concrete element includes arranging a mold about a substantially horizontal roller shaft, the mold having a sleeve-shaped mold wall defining the outer peripheral shape of the concrete element and first and second end rims, each with an inner periphery smaller than the inner periphery of the mold wall at the respective end and defining the end surfaces of the concrete element. The mold is rotatably supported by the roller shaft by abutment at the inner peripheries of the first and second end rims so that the roller shaft upon rotation defines the inner peripheral shape of the concrete elements. The method further includes rotating the shaft to rotate the mold; feeding curable concrete to the rotating mold; stopping the rotation of the mold; and removing the cured concrete element from the mold. The inner perimeter of the mold wall defines an exterior shape of the concrete element that varies along and/or radially to the direction of the rotational axis. There is further provided an arrangement for making such concrete elements. | 12-30-2010 |

| 20120027274 | NONLINEAR RECURSIVE FILTER FOR MEDICAL IMAGE PROCESSING - A new system and method for medical image processing using a nonlinear recursive filter are disclosed. An input signal including two or more pulses received from a medical imaging system is sampled at a predetermined sampling rate. The maximum magnitude, i.e., peak, and/or the occurrence time of the maximum magnitude of the first pulse of the input signal is/are determined using a nonlinear recursive filter. Predicted magnitude values of the tail of the first pulse can be determined and subtracted from the input signal to correct for pileup before determining the maximum magnitude and/or occurrence time of the next pulses. A medical image can be reconstructed using the determined maximum magnitudes and/or the occurrence times of the maximum magnitudes of the pulses of the input signal. The nonlinear recursive filter can be implemented using one or more look-up tables. | 02-02-2012 |

| 20090176144 | FUEL CELL MODULE - The present invention provides a fuel cell, including a composite bipolar plate and gasket connecting bipolar plate. A sub-channel is assembled at a concave side of the gasket corresponding with bipolar plate. Main channels of gas running through both sides of the bipolar plate are arranged at separation positions between the bipolar plate and gas sub-channel. The main channels of gas and the gas sub-channel are connected through the channel. The airtight layer is assembled between the bipolar plate and gasket. With the airtight layer, the bipolar plate and gasket can be locked and fixed together steadily and tightly, so that the spaces of flow channels for different fuels can be definitely separated, without any leakage and mistaken mixture. | 07-09-2009 |

| 20110080512 | ANALOG-TO-DIGITAL CONVERTER FOR IMAGE SENSORS - An analog-to-digital (ADC) converter is disclosed that uses aspects of a single-slope ramp ADC, but with jump steps in the ramp voltage to increase speed. A look-ahead controller can cause a ramped voltage level to jump step and detect the number of analog input signals impacted due to the jump step. If the detected number is below a predetermined threshold, the ramp can be maintained from the new voltage level after the jump. If the detected number is above the predetermined threshold, the ramped voltage level can be returned to its original voltage level and trajectory. Thus, jump steps can be used to increase speed, but dynamic testing can be performed to ensure that error rates due to the jump step are minimized. | 04-07-2011 |

| 20090073297 | TWISTED INPUT PAIR OF FIRST GAIN STAGE FOR HIGH SIGNAL INTEGRITY IN CMOS IMAGE SENSOR - Methods for forming conductors and global bus configurations for reducing an interference signal from electromagnetic interference (EMI) source are provided. First and second conductor lines are formed on an integrated circuit in a twisted pair configuration. A differential amplifier is formed on the integrated circuit and coupled to each of the first and second conductor lines. The first and second signals are respectively transmitted through the first and second conductor lines and are modified by the interference signal. The modified first and second signals are differentially amplified by the differential amplifier so that the interference signal is substantially cancelled. | 03-19-2009 |
