Abstract: A parcel detection system (A) works in connection with a stream of parcels (B), such as might be encountered in connection with bulk mail sorting apparatus. A presence of multiple parcels traveling adjacent one another is detected with a line scan charge coupled device (34). A transducer array is disposed perpendicularly to the stream flow. Specular illumination of edges of the parcels is completed to facilitate capturing an image in the CCD array (34). An analog signal, obtained from the array, includes information representative of a number of adjacent parcels. This information is processed to provide a signal representative of a number of parcels traveling adjacent to one another in the stream.

Abstract: Un système d'éclairage mis au point pour l'inspection vidéo à vitesse rapide comprend un réseau de diodes électroluminescentes utilisé dans l'inspection par intégration à temporisation (TDI) de matières en bande. Les diodes électroluminescentes du réseau peuvent être commandées sélectivement afin de produire un éclairage séquentiel et une image minutieusement régulable d'une section spécifiée d'un échantillon ou de plusieurs échantillons se déplaçant de manière continue. Le système comprend également un réseau d'éléments d'éclairage de fond optionnel contribuant à l'éclairage d'échantillons semi-opaques afin d'inspecter ces derniers.

Abstract: A method and/or system for forming a plastic bottle from a preform without the use of a mold or a complete mold are provided. The technique includes selectively injecting heat into the preform using narrowband irradiation devices emitting irradiation in a narrow wavelength band matching desired absorptive characteristics of selective portions of the preform according to a predetermined heat signature to achieve a three- dimensional heat profile in the preform. The heat profile corresponds to a desired shape of a finished bottle and facilitates self-limiting stretching of the selected portions of the preform to achieve the desired shape. Using the technique, air is selectively injected into the preform to form in free air the finished bottle having the desired shape.

Abstract: This invention relates to a method and apparatus for handling parts ejected from an injection molding machine (10). More particularly, in one aspect, the invention is directed to a system (20) whereby data molded into the ejected part is used to provide useful feedback for the molding process. In another aspect, molded parts formed in a multiple molding die (12) are ejected from the die in a manner to maintain the relative sequential or matrix organization so that useful feedback information can be generated. This system is particularly useful with subsequent machine vision and inspection applications.

Abstract: This application relates to an apparatus (Fig. 3) and method for providing patterned illumination fields for use within process control and article inspection applications. More specifically, it pertains to the use of patterned illuminators (90, 110) to enable visual surface inspection of polished objects (30)such as ball bearings. The use of patterned illuminators properly disposed in relation to a polished part under inspection allows small surface imperfections such as scratches and pits to become visible against the normal surface background. The use of carefully engineered illuminators facilitates advantageous defect-site scattering from generally dark field sources. The patterned nature of the illuminators defined by this invention allows the complete surface (55) of three-dimensional parts to be effectively highlighted using dark field illumination fields.

Abstract: A method and apparatus for on-line quality control of PET containers. An infrared or ultraviolet sensor (10) detects the intensity of electromagnetic radiation transmitted through the wall of a container. A processor (30) uses this signal to calculate density or volume of the external wall of the container.

Abstract: An inspection system is provided comprising at least one detection element (60) sensitive to electromagnetic radiation (20) at a wavelength wherein the object (10) to be inspected is rendered opaque by naturally occurring material molecular absorptions. As such, material defects such as cracks and voids can be detected.

Abstract: A system for direct injection of selected thermal-infrared (IR) wavelength radiation or energy into food items for a wide range of processing purposes is provided. These purposes may include heating, raising or maintaining the temperature of the food articles. The system is especially applicable to operations that require or benefit from the ability to irradiate at specifically selected wavelengths or to pulse or inject the radiation. The system is particularly advantageous when functioning at higher speeds and in a non-contact environment with the target.
