Radio frequency identification (RFID) tags provide a superior level of inventory management, asset tracking and supply chain management over barcode technology, which requires barcodes to be within sight of the reader. RFID technology can be more broadly applied and becomes increasingly accurate by boosting the range at which tags can be read. Engineers at Honeywell leveraged ANSYS HFSS electromagnetic field simulation software to improve upon current RFID systems. Using HFSS, they were able to virtually evaluate new concepts in less time, significantly reducing product development lead time.
The dramatic rise of smart, connected products requires a rapidly increasing communications bandwidth, but the radio frequency spectrum available is growing at a much slower pace than what is needed. One way the fifth generation of cellular wireless technology, 5G, can address this problem is by leveraging beamforming antennas to send different signals to different areas of the cellular network, enabling multiple simultaneous transmissions at the same time on the same frequency. Pivotal Commware is designing the next generation of these beamforming antennas or cellular base stations and other applications, at a fraction of the cost of existing methods. The company’s engineers use ANSYS HFSS to create antenna designs that meet design requirements on the first or second pass, substantially reducing the time required to bring new antennas to market in this highly competitive industry.
Rosenberger leverages mechanical and electrical simulation to provide a superior alternative to traditional spring pins for semiconductor testing.
Keeping a smartphone from overheating is becoming more challenging as increasing numbers of transistors and devices are made to fit into a small, sleek design. Qualcomm engineers have developed a way to use simulation to create a smaller model of the power sources in a smartphone. This model can be solved in a fraction of the time of a full thermal analysis, so that they can look at more operating scenarios. The goal is to create a dynamic power management strategy to selectively direct power where it is needed and keep temperatures down.
Networking experts predict that, by 2021, 66 percent of all internet traffic will be used for high throughput services such as wireless docking, video streaming, cloud backup and virtual reality. Peraso Technologies enables users to cut the cord and go wireless by providing chipsets based on the emerging 802.11ad (WiGig) standard that delivers high-speed wireless throughput in a USB 3.0 stick form factor. Peraso engineers used ANSYS simulation software to solve thermal problems associated with packing high power transmitters into a tiny enclosure.
To provide effective treatment for brain aneurysms, a pioneering healthcare company has developed a digital twin to help physicians place implant devices during surgery. Incorporating ANSYS structural mechanics solutions, the surgeon can simulate the deployment of the implant and determine its optimal sizing and positioning to decrease the risk of failure and reduce operating times.
