| 20080236302 | COMPOUND STORAGE VESSEL HANDLING APPARATUS - Apparatus for handling compound storage vessels such as microtubes having a least one cavity for receiving a compound storage vessel. Each cavity is associated with a respective detector operative to detect the presence of a storage vessel in the cavity. The detector may comprise a spring form extending in the cavity and arranged to be deformed by a storage vessel when introduced into the cavity, and further arranged so that on deformation it closes an electrical switch indicating the presence of the microtube in the cavity. The presence of the spring form also increases friction between the storage vessel and the cavity retaining the storage vessel within the cavity. | 10-02-2008 |

| 20100224780 | BEAM DEVICE SYSTEM COMPRISING A PARTICLE BEAM DEVICE AND AN OPTICAL MICROSCOPE - A beam device, in particular a particle beam device, for analyzing an object is provided, as well as a system comprising a particle beam device and an optical microscope for optically analyzing an object. The beam device simplifies the exchange and reduces the time of the exchange of objects to be examined. The beam device includes at least one beam generator that generates a beam, at least one objective lens that focuses the beam on an object arranged in a holding element. The objective lens comprises at least one connecting element. The holding element may be connected to the connecting element so that the holding element is removable from the connecting element for modification of the object. Alternatively, the holding element may be mounted to a beam column. | 09-09-2010 |

| 20090027117 | Low-Noise, Low-Distortion Digital PWM Amplifier - Systems and methods for performance improvements in digital switching amplifiers using low-pass filtering to reduce noise and distortion. In one embodiment, a digital pulse width modulation (PWM) amplifier includes a signal processing plant configured to receive and process an input audio signal. The amplifier also includes a low-pass filter configured to filter audio signals output by the plant. The filtered output of the plant is added to the input audio signal as feedback. The plant may consist of a modulator and power switch, a noise shaper, or any other type of plant. An analog-to-digital converter (ADC) may be provided to convert the output audio signal to a digital signal. Filtering may be implemented before or after the ADC, and a decimator may be placed after the ADC if it is an oversampling ADC. | 01-29-2009 |
| 20090027118 | Digital PWM Amplifier Having a Low Delay Corrector - Systems and methods for performance improvements in digital switching amplifiers using a low delay corrector. In one embodiment, a digital pulse width modulation (PWM) amplifier includes a signal processing plant configured to receive and process an input audio signal. The amplifier also includes a low delay corrector configured to receive signals output by the plant. The output of the low delay corrector is added to the input audio signal as feedback. The plant may consist of a modulator and power switch, a noise shaper, or any other type of plant. An analog-to-digital converter (ADC) may be provided to convert the output audio signal to a digital signal.

| 20090302938 | LOW DELAY CORRECTOR - A low delay corrector (LDC) unit includes a non-linear function generator and a filter. The nonlinear function generator receives a first signal and outputs a second signal in dependence on the first signal and a transfer function of the nonlinear function generator. The filter is fed in dependence on the second signal output by the nonlinear function generator. The first signal received by the nonlinear function generator is derived in dependence on an input signal provided to an input of the LDC unit and an output of the filter. An output of the LDC unit is derived in dependence on the first signal received by the nonlinear function generator and the second signal output by the nonlinear function generator. | 12-10-2009 |

| 20110179338 | LOSSY CODING OF SIGNALS - A method is described for packing variable-length entropy coded data into a fixed rate data stream along with resolution enhancement data, the method providing tightly constrained propagation of transmission channel errors and graceful degradation of signal resolution as entropy-coded data rate increases. An application to a multiband ADPCM audio codec is also described. | 07-21-2011 |
