摘要:
A system and method for utilizing corner-cube reflector technology for irradiation control in direct radiant heating systems is described. The system and method has application in many types of direct irradiation heating systems and is applicable to both narrowband or broadband directed irradiation heating systems. The purpose and result of the implementation is to improve the overall system efficiency through the redirection of photons back to a targeted item which is being heated or treated with the irradiation energy.

A system for identification and confirmation of legitimate deposit refund containers on which a monetary deposit has been collected. The containers include a marking indicating eligibility for collection of the monetary deposit upon return of the containers. The system includes at least one emitter operative to emit radiation positioned to direct the radiation toward a container, at least one sensor operative to sense the radiation reflected back from the container and a control system operative to drive the at least one emitter, receive information from the at least one sensor, and process the information to determine eligibility for the container for the refund of the monetary deposit.
摘要:
A system for direct injection of selected thermal-infrared (IR) wavelength radiation or energy into articles for a wide range of processing purposes is provided. These purposes may include heating, raising or maintaining the temperature of articles, or stimulating a target item in a range of different industrial, medical, consumer, or commercial circumstances. 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.

A stretch blow molding system that condition preforms such that the temperature distribution within the cross-section of each preform is optimized prior to blow molding operations is provided. The system has a temperature measurement and control system capable of directly monitoring both the outside as well as inside surface temperature of preforms at different stages of transport throughout the thermal conditioning section of the system.

This invention relates to an apparatus and method for inspecting multi-layer plastic containers (10). More particularly, the invention relates to such an apparatus and method whereby optical energy absorbing compounds are added to the materials comprising the layer(s) of the container (10) to facilitate inspection thereof. Apparatus comprises a sensor unit (40), an illumination unit (30) for illuminating a portion of electromagnetic spectrum at a near IR wavelength to an inspection zone (20) which is located between the sensor unit (40) and the illumination unit (30). A processing unit (50) which receives an output of the sensor unit (40) and determines the attributes of the multilayer plastic containers (10).
摘要:
A video inspection system is provided wherein light from a light source is directed through a field lens. The field lens directs the incident light first in the direction of an object under inspection and then, after reflecting from said object, redirecting the reflected light toward the aperture of an imaging lens/camera assembly. This redirection technique results in magnification of selected regions of the object.

A system for detecting a side wall perforation in containers operates non-invasively and at line speeds. A stream of similar containers are communicated to an inspection area. An exterior of each container is illuminated while the container is in the inspection area. Light from an interior of the container is focused, via a lens, to a video camera. Any perforate flaw in the container walls results in a point source of light in the container interior. Since the perforations are relatively small, the point source is created due to diffractive properties of the slit perforation. These diffractive properties facilitate obtaining an image of the flaw from the camera disposed to the interior of the container when the camera is mounted orthogonally to the perforation or parallel to the wall being inspected. In an other embodiment, the relative positions of the light source and camera are interchanged. A method for container inspection is also provided in connection with the afore-noted structure.
摘要:
A video inspection system includes first and second video cameras mounted along parallel axes. A lighting array is pulsed, and resultant light is reflected from a specimen to both cameras. Orientation of the specimen is determined in accordance with an image generated from a first camera. This data is used to isolate a selected portion of the specimen for analysis by an image generated from the second camera.
