摘要： A system for calibrating a magneto-resistive (MR) head includes a biasing circuit and a calibration module. The biasing circuit generates a first current to bias a first head during a calibration mode and a calibrated current to bias the MR head during an operating mode. The calibration module calibrates the first current during the calibration mode by adjusting the first current using nonlinear steps to determine the calibrated current.

摘要： Method determining lookup table (“LUT”) for embedding watermark. For each quantization cell, calculating probabilities that signal point falls into cell. Selecting cell by probabilities. Setting LUT value to watermark value with largest probability, subject to run constraint. For remaining cells, repeating selecting and setting steps. Other method determining quantization ensemble by calculating probability density function for signal points where the watermark value to be embedded. Distortion and robustness functions are formulated. Given robustness or distortion is selected. Functions optimized, and ensemble of quantizers determined with parameters that comply. Other method quantizing in association with lossy compression. Strength of compression determined. Adapting strength of watermark with strength of compression by a mapping. Other method selecting points for embedding watermark. Determine threshold between large and small signal points using statistical method. Select signal points for embedding according to threshold. Also, processors, computer programs, and systems.

摘要： In general terms, the present invention provides a method of automatically scanning an inventory field to allow the selection of a desired item for retrieval. A camera is positioned in the crane trolley located above the field. The camera continuously performs a scan of the field displaying an image to the operator of the items being scanned. This real-time image allows the operator to distinguish between items scanned in the field. The operator can subsequently choose the desired item triggering the camera system to automatically capture desired information from the item which is in turn communicated to an inventory control system. The camera system mitigates the requirement of a second individual to communicate information between the field and the operator.

摘要： An over-power detector for detecting an over-power condition of an electronic apparatus powered by power from an AC power source. The over-power detector includes an over-current detector for detecting whether current used by the apparatus exceeds a settable current threshold. The current threshold is set based on a detection of peak voltage on the AC power source, such that the output of the over-current detector is representative of an over-power condition.
