20120182835 | Systems and Methods for Acquiring and Characterizing Time Varying Signals of Interest - Methods or systems for identifying seismic or acoustic signals of interest originating with moving motorized vehicles or footstep movement or stationary or moving machinery. A related system for monitoring an area includes a plurality of sensing devices each comprising a frame and a piezo-electric sensor element. A monitoring device is coupled to receive information from each of the sensing devices. One method includes providing a processing chain coupled to receive signal data from a sensor device which receives the signals, including a detection stage, a Joint Time Frequency (JTF) domain stage, and a classification stage. The detection stage identifies presence of signals that emerge from the background. The JTF domain stage estimates the state of the signals of interest over time. The classification stage assesses the previously derived information to form a decision about source identity. In one embodiment, the detector stage performs detections on a single cycle basis. | 07-19-2012 |

20090234292 | Seal for Trocar - A seal for use in a trocar, particularly for a trocar for eye surgery, having a seal element, with a seal opening, and an instrument opening. The instrument opening extends along a centre axis on both sides of the seal element all the way through the seal. The seal also has a clamp element for establishing a form-fit connection to an instrument that is inserted at least partially into the instrument opening and through the seal opening. | 09-17-2009 |

20120174676 | Systems and Methods for Acquiring and Characterizing Time Varying Signals of Interest - A sensor system responsive to acoustic or seismic signals. One system includes a frame and a piezo-electric sensor element. The sensor element, responsive to a wavefield of seismic or acoustic energy, is positioned about the frame. Coupling between the sensor element and the frame is so limited as to render direct coupling of the sensor element with the wavefield the predominant means for stimulating the sensor element with seismic energy. Another system includes a frame and a cable element, responsive to a seismic or acoustic wavefield, extending about the frame. Coupling between the cable element and frame is so limited as to render direct coupling of the sensor element with the wavefield the predominant means for stimulating the sensor element with acoustic or seismic energy. The element may be coaxial cable or have piezo-electric properties to generate a charge differential measurable as a voltage between conductors. | 07-12-2012 |
20120323528 | Systems and Methods for Acquiring and Characterizing Time Varying Signals of Interest - Methods of making classifications. One method acquires groups of data, derives features of potential interest in a first data group, and analyzes features using a classification tree and a statistically based classification process to draw a classification conclusion on identity with an associated level of confidence. Features associated with a signal of potential interest may be derived with at least a second group of data. A statistical algorithm may perform linear discrimination analysis, or a quadratic discrimination analysis or a logistic regression classification analysis. A related method includes acquiring signal data with a sensor device comprising piezo-electric material and detecting a signal by performing detections on signal data from the sensor device. Determinations are provided when detections surpass defined thresholds of confidence. | 12-20-2012 |
