Abstract:
An apparatus and method are disclosed for preventing components in an inserter machine from causing the inserter machine to stop or function less than optimally due to lack of proper attention from an operator. Accordingly, various component conditions are categorized based upon two or more levels of urgency, and each component having such a condition signals the category of urgency to an operator.
Abstract:
A stationary optical scanning system for the decoding of a plurality of optically readable information bearing symbols encoded using at least first and second different optical codes, and for the detection of a plurality of optical targets having at least first and second different target configurations and target data signals representative of the differing target configurations, includes a single optical sensor for optically sensing the different target configurations and optical codes as objects affixed with the information bearing symbols continuously pass within a field of view and for generating the target data signals from the sensed field of view. A first target processor receives the target data signals and detects the first target configuration in accordance with the target data signals to provide a first processor detection signal, and a second target processor separate from the first target processor receives the target data signals and detects the second target configuration in accordance with the target data signals to provide a second processor detection signal. A decoder receives the first and second target processor detection signals and selectively decodes the information bearing symbols in accordance with the received detection signals, wherein the first and second target processors and the decoder are coupled to the single optical sensor.

Abstract:
An improved inserter input system and method for transversely cutting a web of printed material into separate sheets, the web including a plurality of separated side-by-side sheets. A set of sheets on the web is transported to the cutting device. One or more of the sheets in the set belongs to a new collation for which sheets have not previously been cut. The system determines whether sufficient collation parking spots exist to accommodate a new collation. If there are no available collation parking spots, and if all of the sheets in the set belong to the new collation, then transverse cutting is delayed until an open collation parking spot becomes available. If there are no available collation parking spots, and if a subset of sheets belong to a prior collation, then the web is partially cut to separate only the sheet, or sheets, that belong to the prior collation. The cutting of the other sheet(s) is delayed until the open collation parking spot becomes available. If there is an available collation parking spot, then the cutting device transversely cuts the entire set of side-by-side sheets.
Abstract:
A flexible buffer transport system for staging accumulated documents for transfer to a synchronous downstream transport. Control of movement of accumulations in the buffer being independent of the length of the documents. The system includes a plurality of roller nips in series. The roller nips are spaced a uniform distance apart. Each of the roller nips are driven by an independently controllable motor in communication with a controller. Position sensors also communicate with the controller. The sensors sense positions of lead and trail edges of accumulations of documents within the buffer transport system. For each sampling period in the operating cycle and for each roller nip, the controller determines motion control. First, the controller determines which nips should be slaved together based on which are needed to control a particular accumulation of documents under its control. The motion of the roller nips are also controlled in accordance with a predetermined algorithm to bring a lead edge of an accumulation within a predetermined gap distance from a trail edge of a downstream accumulation.

Abstract:
A concentric ring target detector receives input pixel data from an optical scanning device. The pixel data represents images on a conveyor belt and moving objects bearing information-encoded labels which are advanced by the conveyor belt. Input pixel data is alternately applied to a pair of FIFO blocks, one of such blocks receiving odd and even pixels from scan line N, the other of the blocks receiving pixels from scan line N-1. Pixels from the FIFO blocks are coupled through a pixel switch to a multi-tap first-in first-out block. Each FIFO block applies data to the pixel switch at one-half the rate at which it was received by the FIFO block to maintain constant throughput without the FIFO's overflowing or emptying. The pixel switch ensures that the pixels from scan lines N and N-1 remain in serial order. Pixels from scan line N and N-1 are shifted through a multi-tap FIFO. The multi-tap FIFO has a plurality of taps that enable reading of each pixel written to the multi-tap FIFO as the pixels are shifted through the FIFO. Various one of the tap outputs are coupled to a pair of template correlators. The image frame represented by the pixels applied to the template correlators are compared to templates in the correlators. The templates represent an image of a concentric ring acquisition target disposed on an information-encoded label. If either template correlator recognizes a predetermined correlation threshold, a detection signal is applied to a detection gate causing a detection signal line to activate at a point where the coordinates of the center of the concentric rings disposed on the information encoded label can be determined.
Abstract:
The system has an optical scanning device formed of a plurality of pixel elements for providing a scan output signal representative of a scanned region of an object. The system has a reflector, an illumination source, a light compensator, and an object positioner. The reflector defines an ellipse. The object positioner disposes the object substantially near the major axis of the ellipse. The illumination source emits and applies light energy to the object disposed at a first focus of the ellipse. The light compensator, which varies the light energy emitted from the illumination source, has one or more dedicated pixels of the optical scanning device. The light compensator also has fiber optical transmitters that receive light transmitted from the illumination source and couple to the dedicated pixels, which are unavailable for receiving reflected light from the scanned region of the object.
Abstract:
The camera system of the present invention simultaneously searches for a number of differing optical acquisition targets. This system may decode, for example, both bar codes and concentric rings. The scan signal is constantly adjusted according to both a dark reference for correcting offset and a white reference for correcting gain. The gain is also corrected according to the scanning rate as well as the amount of illumination present. A measure of this illumination may be applied directly to the optical scanning device by way of a fiber optic cable which transmits light from the illumination source. Optical calibration is eliminated by fixed optics wherein all optical elements are rigidly mounted at very close tolerances. The illumination source is disposed on one focus of an ellipse wherein the other focus is disposed at the maximum scanning distance and the reflector is formed to define the illumination ellipse to maximize the light applied to the object. The various heat producing elements are disposed in sealed compartments which are cooled by forced air which is circulated through a heat exchanger. A real time focusing system is provided wherein the distance from the scanning device to an opposing surface is constantly monitored and the system is constantly focused according to the distance.
