20140260367 | CONTROL SYSTEM AND METHOD FOR A LIQUID DESICCANT AIR DELIVERY SYSTEM - An air delivery system may include a housing, a first liquid-to-air membrane energy exchanger (LAMEE), and a desiccant storage tank. The housing includes a supply air channel and an exhaust air channel. The first LAMEE may be an exhaust LAMEE disposed within an exhaust air channel of the housing. The exhaust LAMEE is configured to receive the outside air during a desiccant regeneration mode in order to regenerate desiccant within the exhaust LAMEE. The desiccant storage tank is in communication with the exhaust LAMEE. The exhaust LAMEE is configured to store regenerated desiccant within the desiccant storage tank. The regenerated desiccant within the desiccant storage tank is configured to be tapped during a normal operation mode. | 09-18-2014 |

20140301622 | METHOD AND APPARATUS TO GENERATE IMAGE DATA - In a method and apparatus for the generation of image data of a moving subject inside a body, raw data are initially acquired for a region encompassing the subject at different measurement points in time, and position overview data for the different measurement points in time are generated on the basis of at least a portion of the raw data. A scattering of the position overview data is then determined, which scattering is dependent on the measurement point in time. Spatial test regions within the position overview data are selected depending on the scattering. Trust parameter values are determined for the individual test regions, and a reconstruction of image data then takes place on the basis of the raw data under consideration of the trust parameter values of the different test regions. | 10-09-2014 |
20150015691 | METHOD AND APPARATUS TO GENERATE IMAGE DATA - In a method and apparatus for the generation of image data of a moving subject, raw data are initially acquired for a region comprising the subject at different measurement points in time in different movement phases of the subject. A reconstruction then takes place of multiple interim image data sets of the subject from the raw data that are respectively associated with different movement phases of the subject. Deviation data are then determined between the interim image data sets of the different movement phases of the subject, and the reconstruction of image data from raw data of different movement phases then takes place under consideration of the deviation data. | 01-15-2015 |

20120121124 | Method for optical pose detection - The tracking and compensation of patient motion during a magnetic resonance imaging (MRI) acquisition is an unsolved problem. A self-encoded marker where each feature on the pattern is augmented with a 2-D barcode is provided. Hence, the marker can be tracked even if it is not completely visible in the camera image. Furthermore, it offers considerable advantages over a simple checkerboard marker in terms of processing speed, since it makes the correspondence search of feature points and marker-model coordinates, which are required for the pose estimation, redundant. Significantly improved accuracy relative to a planar checkerboard pattern is obtained for both phantom experiments and in-vivo experiments with substantial patient motion. In an alternative aspect, a marker having non-coplanar features can be employed to provide improved motion tracking. Such a marker provides depth cues that can be exploited to improve motion tracking. The aspects of non-coplanar patterns and self-encoded patterns can be practiced independently or in combination. | 05-17-2012 |

20120245901 | Finite Impulse Response Filter For Producing Outputs Having Different Phases - A method and system for designing and implementing a finite impulse response (FIR) filter to create a plurality of output signals, each output signal having the same frequency but at a different phase shift from the other output(s), is described. Values are determined for the resistors, or other elements having impedance values, in a FIR filter having a plurality of outputs, such that each output has the same frequency response but a different phase than the other output(s). This is accomplished by the inclusion of a phase factor in the time domain calculation of the resistor values that does not change the response in the frequency domain. The phase shift is constant and independent of the frequency of the output signal. | 09-27-2012 |
20120300888 | VIRTUAL WEAVER ARCHITECTURE FILTER - A virtual Weaver architecture filter is implemented using a sampling mixer that successively processes samples of the input signal in round-robin fashion and provides a sum of the samples as multiplied by coefficients emulating quadrature sinusoidal waveforms. A virtual rather than actual local oscillator is reliably implemented without mismatch. Filtering between the Weaver mixers is eliminated in favour of filtering at the sampling input and effective time division multiplexing is achieved by selecting between resistor combinations that implement different scaling coefficients, resulting in an efficient analog implementation of a virtual Weaver architecture. | 11-29-2012 |

20130115906 | Down-Conversion of Multiple RF Channels - A method and system is disclosed for designing a radio for down-converting RF signals to IF signals by sampling the signals in a round-robin sampling circuit and multiplying the samples by coefficients that are changed at a fixed rate equal to the rate of operation of each of the sampling circuits. The circuit is able to down-convert multiple channels simultaneously to adjacent positions in the IF band, while rejecting unwanted image signals. The method and system avoids the difficulty and cost of directly digitizing the RF signal, allowing each component to operate at a greatly reduced speed. The coefficients are selected to provide the desired transfer function while keeping the output signal centered at a desired frequency. | 05-09-2013 |
20130241647 | Distortion Correction in Class-D Amplifiers - The present application describes an apparatus and method for reducing distortion in a class-D amplifier. The power output section of the amplifier is driven by an adjusted PWM signal, rather than by a PWM signal created directly from the input analog signal. A reference output, designed to closely track the input analog signal, is compared to the amplifier output. The resulting difference is an error signal which is inverted and summed with a second analog signal corresponding to the directly created PWM signal and changes the timing of the voltage transitions of the second analog signal. The changed voltage transitions are used to create the adjusted PWM signal. The inversion of the error signal causes negative feedback which results in the adjustment of the PWM signal being in a direction which reduces the error signal and thus the distortion of the amplifier. | 09-19-2013 |
20140103977 | Use of Frequency Addition in a PLL Control Loop - A method and system is disclosed in which the phase detector in a phase-locked loop is able to run at the fastest speed appropriate for a reference signal. A frequency offset is added, to the output frequency of the phase-locked loop, to alter the frequency fed to the frequency divider which would receive the output frequency in a conventional PLL to an intermediate frequency. The frequency offset is selected so that the ratio of the intermediate frequency to the reference frequency is a simple fraction, and preferably an integer, i.e., the intermediate frequency is a multiple of the reference frequency. In cases where the relationship between the output frequency and the reference frequency is largely relatively prime, the phase detector is thus able to receive signals at the frequency of the reference signal and operate at the fastest speed appropriate for the reference signal. | 04-17-2014 |
