  • Patent number: 5875419
    Abstract: A computer-controlled device for determining relative yarn hairiness. Yarn is moved past a light source to create a yarn shadow, and an imaging device captures the yarn shadow. The imaging device includes a number of separate, closely-spaced light sensing elements, each with an output level related to the amount of light shining on the element. A selected sensing element output level is established as indicative that an element is blocked by the yarn. The width of a number of closely-spaced portions of the yarn is determined, at two different selected sensing elements output levels, to distinguish the yarn hairs from the yarn core.

  • Patent number: 5748505
    Abstract: The sensor array is positioned at a vantage point to detect and calibrate its reference frame to the external reference frame demarcated by light-emitting reference indicia. The sensor array encompasses a wide view calibration field and provides data indicating the spatial position of light sources placed within the calibration field. A tetrahedron framework with light-emitting diodes at the vertices serves as a portable reference target that is placed in front of the feature sensor to be calibrated. The sensor array reads and calibrates the position of the light-emitting diodes at the vertices while the structured light of the feature sensor is projected onto the framework of the reference target. The structured light intersects with and reflects from the reference target, providing the feature sensor with positional and orientation data. These data are correlated to map the coordinate system of the feature sensor to the coordinate system of the external reference frame.

  • Patent number: 5721694
    Abstract: A method and system for filtering a noisy input comprised of an information signal and a noise signal. No prior time domain value information or frequency domain parameter information on the information signal or noise signal is available. A whitening filter renders the noise part of a noise signal into a substantially white noise signal. A fourier transform system provides an amplitude spectrum output and a phase output. A multiplier squares the amplitude spectrum output thus providing a power spectrum output. A zero mean sub-system generates a zero mean power spectrum output from the power spectrum output. A square root sub-system squares the zero mean power spectrum output thus providing a resultant output. An inverse Fourier transform sub-system inversely transforms the resultant output to provide a time domain resultant output. An inverse whitening filter provides a substantially noise free output from the time domain resultant output.

  • Patent number: 5638295
    Abstract: A transfer switch system includes a controller which sends separately timed restart signals over a communications network to an addressable relay associated with each load in order to sequentially restart the loads following a transfer. When the loads are elevators, the controller sends a prepare to transfer signal to each elevator through the associated addressable relay directing the elevator to park at a floor with its doors open and delays making a discretionary transfer until all elevators send a reply message over the network that they are appropriately parked. A message from the utility directing a reduction in use of their power can be sent to the controller over the communications network through an additional remote station. The controller can then transfer to the alternate power source and/or send messages to selected loads to shut down.

  • Patent number: 5586065
    Abstract: Aircraft cabin noise and engine vibration are monitored at selected cabin and engine locations (51a/51b), respectively. An optimizing equation uses aircraft cabin noise information to separately determine for each engine a balance solution (60) that minimizes aircraft cabin noise at the selected cabin locations over the engine RPM range of interest. Next, the balance solutions are used to predict the engine vibration levels (63) that will be produced if the balanced solution is implemented. Then a test (65) is made to determine if the predicted engine vibration levels are acceptable, i.e., below a predetermined level. If acceptable, the balance solutions are used to select balance weights suitable for the engines being balanced (66) and the result displayed (67) for implementation by engine maintenance personnel. If the predicted vibration level is unacceptable, a new balance solution is determined for each engine (68) using the optimizing equation constrained by the allowable vibration level.
