    Abstract: A system and method process for imaging DPM codes by a handheld barcode reader may include outputting a polarized light beam from an exit window of the handheld barcode reader to illuminate a direct part marking (DPM) code positioned on an object over a first time period. A non-polarized light beam may be output via from the exit window of the handheld barcode reader over a second time period. Reflected light from the object including polarized light from the DPM code received via a partially polarized receiving window may be sensed.

  • Patent number: 8461514
    Abstract: A high resolution fiber optic position sensor system including a remote sensor head connected by a pair of optical fibers to an electronic controller unit. The sensor is an electronically passive device that utilizes optical signals only that senses the angular absolute position over the full 360° rotation with a sensing resolution of 13 bit (8196). The sensor modulates the optical signal based on the exact position of the sensor disk. This modulated optical signal is analyzed in the controller and translated into the position signal. Because the sensor head is electrically passive it can be deployed in an EMI/RFI intense environment. Further, it is immune to lightening strikes and can also be located many hundred meters away from the control unit without creating undesirable ground loops.

    Abstract: This application generally relates to methods and systems for detecting spectrophotometer misalignment. In particular, the application may characterize the noise of a spectral measurement relative to a reference substrate known to exhibit a generally linear (flat) spectral output over a known spectrum. From the spectral measurement, a linear regression may be performed on a portion of the spectral output to determine a best fit line and a correlation of determination (“R-squared value”) may be determined correlated the measured data to the best fit line. Finally, the R squared value may be compared to a predetermined threshold R squared value to determine if the sensor is misaligned beyond an acceptable amount. If so, an alert may be generated.

  • Publication number: 20080237504
    Abstract: A position detecting devices includes a scale, a sensor, and a control section. The scale has a plurality of light emitting elements located at spacings along a direction in which a movable member is moved. Mounted on the member, the sensor detects light from at least one of the elements within a predetermined detection range longer than a largest one of the spacings, and outputs a light reception signal according to a position where the light is received within the range. The control section drives the elements individually, receives the signal from the sensor, and has a storage section for storing information on positions of the elements in the scale. Upon receipt of the signal, the control section retrieves from the storage section information on a located position of one of the light emitting elements that is being driven, and calculates a position of the member based on the retrieved information and the received signal.
