Abstract: A processing system (10) and a corresponding method are provided for processing work products (WP), including food items, to locate and quantify voids, undercuts and similar anomalies in the work products. The work products are conveyed past an X-ray scanner (14) by a conveyance device (12). Data from the X-ray scanning is transmitted to control system (18). Simultaneously with the X-ray scanning of the work product, the work product is optically scanned at the same location on the work product where X-ray scanning is occurring. The data from the optical scanner is also transmitted to the control system. Such data is analyzed to develop or generate the thickness profile of the work product. From the differences in the thickness profiles generated from the X-ray scanning data versus the optical scanning data, the location of voids, undercuts and similar anomalies can be determined by the control system.

Abstract: A method and system are provided for automatically portioning workpieces, such as food products, by simulating portioning the workpieces in accordance with the one or more desired shapes of the final piece(s) as a directly controlled physical characteristic (parameter/specification) as well as one or more resulting indirectly controlled physical characteristics (parameters/specifications). The desired shape(s) of the final piece(s) are defined by a plurality of manipulatable reference coordinates. A workpiece is scanned to obtain scanning information, then portioning of the workpiece is simulated in accordance with the desired shape(s) of the final piece(s) defined by the directly controlled reference coordinates, thereby to determine the one or more indirectly controlled physical characteristics of the one or more final pieces to be portioned from the workpiece.

Abstract: A method and system are provided for automatically portioning workpieces, such as food products, into both shape and other user-defined specification(s). Workpieces are portioned both to shape and weight, such as to a weight-specific uniform shape, by adjusting (e.g., scaling up and down or slightly modifying) a desired template shape until the desired weight is achieved depending on the varying thickness of each workpiece. For example, from a thicker workpiece, a smaller-sized piece having a predefined shape and weight is portioned, while from a thinner workpiece, a larger-sized piece having the same predefined shape and weight is portioned. The system permits a user to scan in and edit a desired (reference) shape to be used as a template in the portioning process.

Abstract: Sprockets (22) and (42) are engaged with a conveyor belt (18) itself or a chain (28) coupled to the belt. An encoder is used to determine the differential of the rotation of the sprockets. From that information, the instantaneous pitch of the conveyor belt located between the first and second rotational axes can be determined, and from that information the speed of the belt can be determined. This information can be used to control work tools or other devices that act on work products being carried by the conveyor belt.

Abstract: A method is provided for classifying incoming products (e.g., chicken butterflies) to be portioned into two or more types of end products (e.g., sandwich portions, strips, nuggets, etc.) to meet production goals. The method includes generally five steps. First, information on incoming products is received. Second, for each incoming product, a parameter value (e.g., the weight of an end product to be produced from the incoming product) is calculated for each of the two or more types of end products that may be produced from the incoming product. Third, the calculated parameter values for the incoming products for the two or more types of end products, respectively, are normalized so as to meet the production goals while at the same time achieving optimum parameter values. Fourth, for each incoming product, the end product with the best (e.g., largest) normalized parameter value is selected as the end product to be produced from the incoming product.

Abstract: A portioning system (10) for cutting a work product (13) into a diced pattern as the work product is being carried by a conveyor (12). A cutter actuator (17) moves at least one cutter (18) parallel and transverse to the conveyor (12) either singularly or simultaneously at a speed significantly faster than the travel speed of the conveyor. A control system (220) is capable of controlling the direction and speed of movement of the cutter (18) and the conveyor (12) according to one or more directly controlled parameters including cutter pattern width, belt speed, cutter movement speed, cutter direction of movement, shape of desired end product(s), weight of desired end product(s), size of desired end product(s).

Abstract: A conveyor (12) moves a workpiece (WP) past an x-ray source (14) to detect existence and location of any undesirable material included in the workpiece, such as bones, fat, metal, etc. Thereafter, the conveyor carries the workpiece further, wherein a cutter (22) segments the detected undesirable material from the workpiece into a segmented portion (SP) having a visually distinguishable shape, such as square, round, triangular, etc. A worker stationed downstream of the cutter along the conveyor may then easily spot the segmented portion (SP) in a distinguishable shape and offload the segmented portion from the conveyor, while leaving the rest of the workpiece (WP) on the conveyor for further processing. Alternatively, a pickup device (24) may be used to automatically offload the segmented portion from the conveyor. A computer (18) keeps track of the locations of the workpiece and the segmented portion at all times.

Abstract: A computer controlled method and apparatus for meat slabbing according to updated information from the meat product and/or the slab cut from the meat product. Such information may include the weight and fat content of the cut slab. This information may be used to reoptimize the slabbing of the meat product and also may be used to further process the cut slab. Such processing might include marking the location of fat to be trimmed, trimming the fat from the slab, portioning the slab and sorting the slab in accordance with preselected parameters.

Abstract: Disclosed is a digital micromirror device (DMD) based projector in which the position of a stylus with respect to a projected image can be determined automatically. In one embodiment, the stylus includes a detector capable of detecting illumination from a single pixel and the plurality of pixels in the DMD array are sequentially energized until a pixel reflects light to the stylus detector. Since the location of that pixel is known, the position of the stylus adjacent that pixel on the image is also known. In another embodiment, light is emitted from the stylus and the DMD array is sequenced in order to reflect light from the array to a photodetector. Again, when a pixel is sequenced so as to reflect light to the detector, the position of the stylus with respect to the image is related to the image of the pixel with respect to the pixel's location in the array.

Abstract: A method and system for weighing an object as it is carried on a conveyor past an x-ray source. X-rays from the x-ray source pass through the object, are attenuated in proportion to the mass of the object through which they pass, and impinge upon an x-ray detector array. X-ray detector array includes a layer of scintillating material that produces light in response to the intensity of the x-rays and a plurality of photodiodes to detect the light. The intensity of the x-rays received at the x-ray detector array is indicated by signals produced by the photodiodes, which are periodically scanned by a processor. The photodiode signals are each converted to a value representing the average areal density for a volume element extending above the photodiode into the object. Using the average areal density for each volume element and the size of each volume element, the processor determines the mass of the volume element.
