Vicinity manufacturing9/3/2023 The wavelengths of these devices correspond to a spatial resolution of a few centimeters. ![]() Even Bluetooth and cell phone signals can be used. Using holographic data processing, the very small bandwidths of typical household Wi-Fi transmitters operating in the 2.4 and 5 gigahertz bands were sufficient for the researchers. Hitherto, generating images from microwave radiation required special-purpose transmitters with large bandwidths. For that, you would need to go around the building with a large antenna, which would hardly go unnoticed. “However, it is rather unlikely that this process will be used for the view into foreign bedrooms in the near future. After all, to a certain degree even encrypted signals transmit an image of their surroundings to the outside world,” said the project leader, Friedemann Reinhard. ![]() “Of course, this raises privacy questions. The novelty is that an entire space can be imaged via holographic processing of Wi-Fi or cell phone signals. Processes that allow the localization of microwave radiation, even through walls, or in which changes in a signal pattern signify the presence of a person already exist. The researchers envision fields of deployment especially in the domain of industry 4.0 - automated industrial facilities, in which localizing parts and devices is often difficult. “Using this technology, we can generate a three-dimensional image of the space around the Wi-Fi transmitter, as if our eyes could see microwave radiation,” said Friedemann Reinhard, director of the Emmy Noether Research Group for Quantum Sensors at the Walter Schottky Institute of the TU Munich. Friedenmann Reinhard and Philipp Holl report in the current issue of the renowned scientific journal Physical Review Letters. While optical holograms require elaborate laser technology, generating holograms with the microwave radiation of a Wi-Fi transmitter requires merely one fixed and one movable antenna, as Dr. Just like peering through a window, holograms project a seemingly three-dimensional image. Industrial facility operators could use this to track objects as they move through the production hall. This process takes less than a handful of minutes and companies can now easily perform accurate and quick lot trace recalls whether it be for a regulatory audit or a real time scenario.– Scientists at the Technical University of Munich (TUM) have developed a holographic imaging process that depicts the radiation of a Wi-Fi transmitter to generate three-dimensional images of the surrounding environment. This report, which can be customized, currently shows what production batch tickets consumed the Item/Lot combination, but also take that a step further showing the sales information for items that consumed our tainted lot. While this data is great, as the user generates the lot trace report, they can then view more information. Once we select the trace direction, we can see the path of this item/lot combination. The first line, CH-002184 is the lot number for FL-1001 that consumed FL-RM1005…Incidentally, FL-1001 lot CH-002184 was subsequently used in another batch to product lot 11 for item FL-7001-25…Īgain, the idea is that any item that came in contact with item FL-RM1005 lot 002-002 needs to be identified. We see the list of Item Lot Numbers that consumed that lot. We can see the first level of batches that consumed this item. In this example, we’re selecting lot 002-002 for component ID FL-RM1005 The upward trace will take a specific component/lot and track every production ticket that consumed that lot OR any production ticket that may have used a product that contains that lot. ![]() The downward trace would take a specific lot for an item and show the components/lots that went into that particular item. ![]() Here we have the option to trace an item upward or downward. Using Vicinity Manufacturing with Microsoft Dynamics, companies can perform their mock recalls within minutes. Furthermore, to meet the requirements of many compliance agencies, companies will be asked to perform mock recalls where they are graded based on both accuracy and timeliness.įor many companies, this can be quite a lengthy process having to sort through stacks of handwritten documents for each production ticket…That mock recall needs to be a quick and accurate process. In the event of tainted material, manufacturers need to be able to quickly determine who and what has been affected by this item. Products need to be safe for consumers, which is why companies go through rigorous quality testing upon receipt of materials and prior to releasing finished product to the public.
