摘要： Systems and methods for reducing erroneous weighing of items such as by detecting items extending beyond a periphery of a weigh platter whereby in one configuration, the system employs a light guide for routing a light beam to a detector operative to detect interruption of the beam due to an item encroaching upon or overhanging an edge of the platter. In another configuration, the scale includes a perimeter gap between the platter outer edge and scanner housing frame or checkout counter, a light beam directed angularly upward through the gap is partially obstructed by the frame and platter whereby light exits the gap forming a light plane, wherein an object placed on the platter extending across the gap intersects the light plane thus scattering light rays, some of which are sensed by a detector. Various indicators for alerting the operator of off-scale detection are also described.

摘要： A compact scan module including a resonantly driven dithering assembly employing feedback and/or travel stops for scanning an illumination beam of a barcode scanner. In one construction the dithering assembly includes one or more travel stops to limit the motion of the mirror assembly with the two travel stop(s) fabricated from damped resilient material to absorb excess energy imparted on the dithering assembly. A first preferred feedback embodiment employs a Hall effect sensor wherein a feedback magnet is connected to the dithering assembly with a Hall effect sensor positioned to sense the varying magnetic field resulting from the varying position of the feedback magnet. A second feedback embodiment incorporates piezoelectric feedback wherein one or more piezoelectric strain sensors are attached to the bending member to provide the position sensing.

摘要： Systems and methods are provided for reducing erroneous weighing of items by detecting items extending beyond a peripheral edge of a weigh platter associated with a data reader. For example, in response to a weigh request a scale guard module acquires data indicative of whether an item extends between the weigh platter and another surface, compares the acquired data to reference data, and based on the comparison, determines whether an item extends off the weigh platter and thus on to another surface. The scale guard module may utilize non-electromagnetic compression waves, radio waves, a portion of a data reader's scan field to scan a set of patterns extending along at least one edge of the weigh platter, an imaging based scanner to capture an image of at least one edge of the weigh platter, light beams extending along at least one edge of the weigh platter, or any combination thereof.

摘要： A system and method for improving the accuracy of edge detection under high Inter-Symbol Interference, or ISI, conditions is disclosed. The amplified and filtered first derivative signal is offset by equal amounts in both directions to generate positive and negative offsets which serve as inputs to negative and positive peak detectors, respectively. The offset is determined by a fast adaptive peak detector provided by attenuating and AC-coupling the first derivative signal to the positive supply to drive a peak detector with a fairly short attack time, such that its output is nearly settled on the first peak of the first derivative signal, but having a decay time long enough to keep the threshold level approximately constant across the label. Peaks are qualified if the peak in question differs in amplitude from the previously qualified peak by the offset amount. Thus, peaks are qualified if their modulation depth exceeds a threshold, regardless of the absolute level of the peaks (such qualification strategy is referred to as modulation depth gating).
摘要翻译：公开了一种用于在高符号间干扰或ISI条件下提高边缘检测精度的系统和方法。放大和滤波的一阶导数信号在两个方向上偏移相等的量，以产生分别用作负峰值检测器和正峰值检测器的正和负偏移量。该偏移由快速自适应峰值检测器确定，该快速自适应峰值检测器通过将一阶导数信号衰减和AC耦合到正电源来提供，以驱动具有相当短的发射时间的峰值检测器，使得其输出几乎在一阶导数信号，但具有足够长的衰减时间，以使标签上的阈值水平保持不变。如果所讨论的峰值与先前合格的峰值相差偏移量，则峰值是合格的。因此，无论峰值的绝对电平如何（这种限定策略称为调制深度选通），如果峰值的调制深度超过阈值，则它们是合格的。
