| 20090055245 | SURVEY FRAUD DETECTION SYSTEM AND METHOD - A method of filtering fraudulent responses from survey data including responses to survey questions received from survey takers and a response time for each response. For each question, any responses to the question having a response time less than a minimum time required to provide a thoughtful response are filtered from the survey data. Optionally, for each survey taker, a number of responses filtered from the survey data is determined. If this number exceeds a threshold, all responses provided by the survey taker are filtered from the survey data. The method may determine whether responses provided by each survey taker to attributes of a matrix question include a pattern. If a survey taker's responses include the pattern and were provided in less than the minimum time required to provide a thoughtful response to the matrix question, all responses provided by the survey taker are filtered from the survey data. | 02-26-2009 |

| 20100095967 | FLAT-FOLDED PERSONAL RESPIRATORY PROTECTION DEVICES - A personal respiratory protection device includes a multi-layered structure and first and second means for attaching a headband to hold the device in position on a wearer's face. The multilayered structure includes a filter medium and is divided into a flat upper panel having an upper peripheral edge, a flat non-rectangular central panel and a lower panel having a lower peripheral edge. The central panel is separated from each of the upper and lower panels by first and second lines of demarcation. The first and second lines of demarcation converge towards the first and second means for attaching a headband. The multi-layered structure is capable of being folded at the respective lines of demarcation so that the device can be folded flat for storage and can be opened to form a cup-shaped off the face air chamber over the nose and mouth of the wearer while the upper peripheral edge and the lower peripheral edge contact the wearer's face when the device is in use. | 04-22-2010 |

| 20100220159 | FLUSH PUMP FOR INK SUPPLY SYSTEM - An ink supply system for an ink jet printer has an ink circuit including a plurality of circuit components and fluid paths for conveying fluid between components. A manifold defines the fluid paths and a plurality of ports in fluid communication with the paths. One of the fluid paths is a solvent supply path for connection to a source of solvent. A second of the fluid paths being a solvent flush path for delivering solvent to an outlet for connection to a print head of the printer. A flush pump is disposed at the manifold between the first and second paths and in fluid communication therewith, the pump being configured to pump the solvent into the solvent flush path. | 09-02-2010 |

| 20090147977 | HEARING AID SYSTEM COMPRISING A MATCHED FILTER AND A MEASUREMENT METHOD - The invention relates to a hearing aid system comprising an input transducer for converting an input sound signal comprising an information signal part of a known waveform and a background noise part to an electrical analogue input signal, optionally an A/D converter for converting the electrical input signal to a digital input signal. The invention further relates to a method of making a critical gain measurement. The object of the present invention is to improve the signal-to-noise ratio of a signal to be measured or detected in a hearing instrument compared to prior art solutions. The problem is solved in that a matched filter receiving said analogue or digital input signal and optimized to improve the identification of the information signal part from the noisy input signal. An advantage of the invention is that it provides an alternative scheme for improving signal to noise ratio of a hearing aid. The invention may e.g. be used for the customization of hearing aid parameters in cooperation with fitting software and/or for improving signal to noise ratio of a detected or measured signal. | 06-11-2009 |
| 20110026725 | METHOD FOR MONITORING THE INFLUENCE OF AMBIENT NOISE ON STOCHASTIC GRADIENT ALGORITHMS DURING IDENTIFICATION OF LINEAR TIME-INVARIANT SYSTEMS - A hearing aid system and a method of estimating ambient noise in a listening device includes an input transducer and an output transducer, an electrical forward path between the input transducer and the output transducer providing a forward gain, an electrical feedback path comprising an adaptive filter for estimating the acoustic feedback gain from the output transducer to the input transducer. A method determines the quality of a critical gain measurement for a listening device. The method comprises a) monitoring the energy of the first-difference of the filter coefficients of the adaptive filter over time and b) applying a predefined threshold criterion to the change in energy content from one time instance to another to determine an acceptable impact of the ambient noise. This technique may e.g. be used for the fitting of hearing instruments where background noise is variable. | 02-03-2011 |
