Dispelling Light Sources

Philips is offering an innovative technology to dispel humans (and animals) from an area where they are unwanted. The new and patented dispelling light source (DLS) concept is based on disturbance of humans and/or animals using photosensitive stimuli. When switching a DLS system to the specifically programmed flickering mode, it directly induces negative psychological and/or physiological effects such as aversion, discomfort, dazzling, disorientation, fear, or malaise. As a direct result, humans and/or animals will be dispelled from the site. Proper selection of the flicker frequency avoids triggering of photosensitive epilepsy.

DLS-suitable lighting systems comprise high-pressure gas discharge lamps, where the high-pressure sodium lamp exhibits a particular provocative effect. A strong feature of DLS systems is its dual-mode operation: the system operates in the normal application-dependent illumination mode until the system driver is externally triggered by a proximity detector. Once humans and/or animals have been dispelled, the system switches back to normal lamp operation.

Gripping Hand or Chuck Technology for Automated Applications

A company is seeking unique technologies for automated hand, chuck, and grip product assembly applications (not CNC machining). Multiple sizes of gripping device are acceptable for different sized parts. The chuck or hand technology should be general purpose in nature, and show versatility in its ability to grip or manipulate parts of various forms and shapes in order to be applicable to a wide range of assembly processes.

Natural Technology for Food Preservation

Technologies are sought that will provide a natural method for extending shelf life, the prevention of food deterioration (oxidation and/or spoilage), and growth of pathogenic micro-organisms along the full chain of fresh or processed food. The solution could be effective at any stage, from feedstock to point of processing, through to consumer use. It could be a new natural preservative (plant extract, food-grade cultures), natural process/additive for enhancing the activity of existing known natural preservatives, or antimicrobial films or coatings.

Getting Real-Time Performance From A Full-Featured OS

Spend a few minutes at your local electronics store and it’s obvious — the mobile phone is a device that far surpasses its original intent. With respect to functionality, today’s mobile phone goes well beyond the ability to make calls and store phone numbers. It also synchs up with your desktop’s calendar and address book, it can take pictures, play and store music, and receive emails.

Selecting the Optimal Vision Equipment to Meet Automation Needs

Solving a machine vision application, whether it involves quality inspection, part verification or any number of additional tasks, requires taking several factors into consideration. The most important part of this process is analyzing the target object and its inspection environment, and then specifying the tolerance between “good” parts and “bad” parts. From this information, one can choose the optimal lighting, vision sensor and lens for the application at hand.

IDS Camera Automates Inspection

Until now, machine-based surface inspection methods have checked visual quality by means of direct or transmitted light in conjunction with a camera system. When it comes to the automated inspection of reflective and smooth surfaces, however, these methods involve problems. The resulting reflections need to be either eliminated or included in the measuring process. Consequently, complex lighting conditions using polarized light or fringed projection in a darkroom are required, or the objects need to be positioned with high precision and completely shock-free. Whichever solution is employed, neither permits an automated 100% in-process inspection.
