Abstract: A biasing device can supply a bias voltage to bias-able element by coupling a bias circuit to the bias-able element, coupling a state adjusting device to the biasing circuit, configuring the state adjusting device to 1) increase an initial biasing voltage by a first amount when an intermediate voltage threshold exceeds a voltage drop across the bias-able element and 2) increment the increased initial bias voltage by a second amount, where the second amount is a fraction of the first amount, until the voltage drop across the bias-able element substantially equals a predetermined bias voltage. The bias circuit of the biasing device can include a variable resistance, which is controlled by the state adjusting device and configured to vary the biasing voltage, in series with the bias-able element. The variable resistance can include a first variable resistance coupled in series to a first terminal of the bias-able element and a second variable resistance coupled in series to a second terminal of the bias-able element.

Abstract: A system is provided to adjust a separation distance between a read/write sensing head and a data storage medium surface in a hard disk. The thermal expansion of the sensing head based on heat generated by power dissipated through the sensing head is precisely controlled. When electrical resistance is not accurately known, a calibration is performed in which a specific input value is matched to a predetermined reference electrical power. The matching is done through a reference voltage source, that remains at a fixed value, and a calibration factor is successively adjusted through a feedback loop until an optimum value of the calibration factor is obtained. At the conclusion of the calibration process, the feedback loop is disabled and the optimally attained value of the calibration constant is frozen. The electronic circuit to implement the proposed system is based on cost effective CMOS technology.

Abstract: 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.

Abstract: A system and method are provided for detecting extraneous material, often referred to as scarf, in the interior of a tubular steel product. The system is arranged to illuminate one end of the tube as it passes through the field of view of an imaging system, preferably a Smart Camera. The camera obtains images and processes the images to determine if scarf is present in the interior of the tube. Preferably a processor determines the percentage of dark pixels in the interior of the tube as detected in the image and if a predetermined threshold is met or exceeded, the tube fails. A blob sensor is also preferably used to avoid false positives where the dark pixels do not have a certain amount of connectivity.

Abstract: An RMR is biased with constant power. Voltages are applied across at least two variable resistors, which are coupled on opposing ends of the RMR, to establish a current to the RMR, wherein the current is based on the voltages and on resistance values of the at least two variable resistors. A voltage corresponding to the established current of the RMR is amplified. The amplified voltage is compared to a reference voltage, wherein the reference voltage is based on a target power for the RMR. The resistance values of the at least two variable resistors are modified so that the amplified voltage approaches the reference voltage. Modifying the resistance values of the at least two variable resistors in this manner is seen to bias the RMR with constant power, since the reference voltage is based on a target power for the RMR.
