DISINFECTION OF HIGH TOUCH/TRAFFIC AREAS


S


teriLumen’s goal is to help hospitals combat healthcare associated infections with its patented UVC-based


disinfection solutions. For disinfecting high-touch surfaces, SteriLumen launched its Lumicide Ribbon. The


system is designed to always be on, providing maximum germicidal irradiation to the surface it is disinfecting. Since UVC light is harmful to people, the Lumicide system has a dual, redundant motion sensor integrated into it ensuring that the system is switched off when someone approaches. SteriLumen relies on the ILT2400 UVGI Light Measurement System, available from


Quantum Design UK & Ireland, as a critical verification and validation tool. Prior to purchasing the ILT2400, SteriLumen had been relying on software modelling to predict where the UV light was going, and at what threshold a person would be exposed to UV hazard when the device was on. It was also relying on outside testing services to validate that its system was emitting the proper amount of light, or dose, to effectively inactivate germs. The ILT2400 enabled the company to pull that capability in-house, saving time and resources in outside testing services.

3D PRINTED DEADWEIGHT TEST MACHINE


The process involves applying weights to a load cell in evenly spaced increments. This allows a technician to determine the load cell’s characteristics, such as hysteresis and linearity, as well as attributing the mV/V values produced by the load cell at each increment to a known load. At Interface, we decided to build a 10N deadweight tension and


A


compression machine as a working scale model and part of the design process for a larger deadweight machine. Our aim is to achieve an uncertainty of applied force of +/-0.02% offering the ability to work to a Class 0.5 per ISO-376. Using CAD and 3D printing, we built a 70cm tall machine.


Featuring 10x 1N weights and nearly 70 individual parts, the machine has motorised lead screw is used to lift two moving mechanisms that hold the load cell.

ISMART RESEARCH GROUP AND WOOLLAM IR-VASE II


led by Dr. Nikolaos Kalfagiannis, focuses on the optical and electronic properties of materials and thin films for nano-photonic and electronic applications, specifically metal-oxides. iSMART is equipped with a J. A. Woollam


C


Infrared Variable Angle Spectroscopic Ellipsometer (IR VASE II), capable of providing the optical constants of materials in the extended spectral range from 1.6 – 40 microns. Supplied by Quantum Design UK and Ireland (QDUKI), the IR VASE II is located at the Medical Technologies Innovation Facility (MTIF). QDUKI and MTIF have entered into a partnership to provide access to the IR VASE II on an ad hoc contract basis. QDUKI and MTIF are co-hosting a free Spectroscopic Ellipsometry Workshop in September, where Dr. Kalfagiannis will give several talks.

SICK SWITCHES UP TO SMART VERSATILITY WITH NEXT- GENERATION SLG-2 LIGHT GRIDS


S


ICK has developed its next-generation SLG-2 light grids to combine higher levels of optical performance with smart sensor capability in an ultra-slim housing. The SICK


SLG-2 extends integration versatility beyond switched outputs to incorporate measurement, classification, and Smart Tasks, while also providing data for diagnostic evaluation. The SICK SLG-2 family offers a choice of resolutions and includes a crossbeam version


for detection of very thin or flat objects. The addition of an IO-link interface adds extra value for machine-builders and end users, opening up new opportunities to automate factory and materials handling applications. Just 12mm x 24mm in size, the SICK SLG-2 light grids come in Slim or Flat variants, so


they can be configured horizontally or vertically to fit snugly into machines or conveyors. They enable versatile machine and robotic integration with rapid response times that ensure completely reliable performance even at high production speeds. The SICK SLG-2 can also be integrated neatly into mechanical doors, gates and lifts. The SICK SLG-2 is therefore ideal for duties such as overhang or leading-edge


detection, classifying products of multiple heights, or loop and sagging control of sheet materials. The addition of IO-Link extends the SICK SLG-2’s capabilities to include height, width,


and length measurement. It enables individual beams to be controlled or blanked, as well as the feedback of diagnostic information for condition monitoring. A Smart Task is available to set zones to solve product classification and quality applications. Zoning also avoids the costly cabling needed to configure multiple photocells, an advantage for example in entry and exit applications such as industrial doors and gates. “Whether you are designing a new machine or want to replace an existing light grid


to take advantage of IO-Link functionality, the SICK SLG-2 offers exceptional versatility at this price/performance level,” says David Hannaby, SICK’s UK Product Manager for Presence Detection. “With IO-Link, the SLG-2 can not only provide height, length and width values, it can


also detect an object’s position in the light grid. It can output information on the status of every single beam and offers all the benefits of real-time diagnostics to monitor operational status and quality of run.” The SICK SLG-2 Slim and Flat come with 10mm, 25mm or 50mm beam spacing and can


detect objects with a height of between 100mm and 2400mm. SICK’s patented new optical technology ensures the SLG’s operation is immune to interference from cross talk, reflections, or ambient light conditions. The SLG-2 achieves response times as fast as 2.1ms depending on the number of beams. The compact SICK SLG-2 Slim and Flat make mounting simple, using either sliding nuts


or quick-mounting accessories, with options for M8 or M12 4-pin cable connections. Set up is easy via with the option to use an external teach-in button on the device.
