Abstract: A linear regulator for outputting a regulated voltage with improved rejection of high frequency components in the power supply. The linear regulator includes an op-amp connected in a linear feedback loop to drive first and second current legs based on a voltage reference. An output driver includes a load capacitance across which the regulated voltage is output, and further includes a ratio-driven current mirror having a mirror ratio defined by relative sizes of active devices in the first and second current legs, as compared with relative sizes of active devices in the output driver. Because the output driver and its load capacitance are provided outside the linear feedback loop, large values for the load capacitance can be selected without destabilization of the feedback loop. Thus, the value of the load capacitance can be chosen at any value according to frequency rejection requirements.

Abstract: A buffer for the input to an A/D converter operates in two stages. During the first stage, the input is not provided directly to the A/D converter; rather, a buffered output which corresponds to the input is provided to the A/D converter so as to pre-charge the sampling capacitor of the A/D converter to a value that is substantially close to the input. In the second stage, the input is provided directly to the A/D converter, which charges its sampling capacitor to the value of the input. Because the sampling capacitor is pre-charged to a value that is substantially close to the input, and because the sampling capacitor is charged to this value through a buffer, reflections back into the input which otherwise might have been caused by a difference between the value stored on the sampling capacitor and the input are largely avoided.

Abstract: A radar system is described for use in vehicular applications. The radar system is particularly suited to backup warning systems and side-object warning systems. The radar minimizes many of the problems found in the prior art by providing programmable delays and programmable gain. The radar uses a range search algorithm to detect and sort targets at various ranges within the field of view of the radar. Each target range corresponds to a particular delay and gain setting. The radar searches for targets at the various ranges by running a target search algorithm. For each target range, the search algorithm causes the proper time delay and gain setting. Targets within the selected range are detected and catalogued. A display is used to warn the driver of the vehicle of the presence of targets at the various ranges. The warning may be visual and/or audible.

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.

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.
