关于客户
罗斯·麦克法兰手和上肢中心 (HULC) 是一家备受尊敬的世界知名卓越中心，致力于教育、研究以及诊断、护理和治疗手部、手腕、肘部和肩部复杂疾病的患者。除此之外，该中心还专门从事乳房重建、复杂伤口护理以及许多其他需要专门护理的疾病。该中心位于安大略省伦敦，在 Louis Ferreira 博士的指导下，采用先进的技术和方法为患者提供最好的护理。
挑战
位于安大略省伦敦的罗斯麦克法兰手和上肢中心 (HULC) 在评估骨应力的生物力学方面面临着重大挑战。该中心在 Louis Ferreira 博士的指导下，使用高分辨率扫描仪进行 CT 扫描的人体骨骼标本。这个过程保留了大部分内部骨小梁的微观结构几何形状。然而，挑战在于，实验模型的许多测量要么是禁止的，要么不可能直接在样本上进行测量。这对于肩关节炎患者尤其重要，他们通常通过用植入物替换患病关节进行手术治疗。该中心需要一种方法来模拟不同植入物类型如何影响骨应力，从而影响手术的寿命。
解决方案
该解决方案以 Altair SimSolid™ 的形式出现，这是一款仿真软件，可以进行与物理模型相匹配的模拟机械测试。将人体骨骼标本模型导入 SimSolid 进行测试。该软件使 HULC 能够增强其实验模型的测量结果，否则这些测量结果将无法或无法直接在样本上进行测量。例如，在肩关节植入物的情况下，SimSolid 允许通过 60 微米分辨率 CT 扫描测试高分辨率骨模型。同样，对于人类头骨，实验模型使用 3D 打印的活塞支架来重建人体头部的肌肉活动线。该实验在 SimSolid 中重新创建，以便测量无法在样本上放置应变计的区域的骨应变。

IoT platform Enables Safety Solutions for U.S. School Districts
Designed to alert drivers when schoolchildren are present, especially in low-visibility conditions, school-zone flasher signals are typically updated manually at each school. The switching is based on the school calendar and manually changed when an unexpected early dismissal occurs, as in the case of a weather-event altering the normal schedule. The process to reprogram the flashers requires a significant effort by school district personnel to implement due to the large number of warning flashers installed across an entire school district.

Revolutionizing Medical Training in India: GSL Smart Lab and the LAP Mentor
The GSL SMART Lab, a collective effort of the GSL College of Medicine and the GSL College of Nursing and Health Science, was facing a challenge in providing superior training to healthcare professionals. As clinical medicine was becoming more focused on patient safety and quality of care, the need for medical simulation to bridge the educational gap between the classroom and the clinical environment was becoming increasingly apparent. Dr. Sandeep Ganni, the director of the GSL SMART Lab, envisioned a world-class surgical and medical training center where physicians and healthcare professionals could learn skills through simulation training. He was looking for different simulators for different specialties to provide both basic and advanced simulation training. For laparoscopic surgery, he was interested in a high fidelity simulator that could provide basic surgical and suturing skills training for international accreditation as well as specific hands-on training in complex laparoscopic procedures for practicing physicians in India.

Implementing Robotic Surgery Training Simulator for Enhanced Surgical Proficiency
Fundacio Puigvert, a leading European medical center specializing in Urology, Nephrology, and Andrology, faced a significant challenge in training its surgical residents. The institution recognized the need for a more standardized and comprehensive training curriculum, particularly in the area of robotic surgery. The challenge was underscored by two independent studies showing that less than 5% of residents in Italian and German residency programs could perform major or complex procedures by the end of their residency. The institution sought to establish a virtual reality simulation lab that would include endourological, laparoscopic, and robotic platforms. However, they needed a simulator that could replicate both the hardware and software of the robotic Da Vinci console used in the operating room, without being connected to the actual physical console. They also required a system that could provide both basic and advanced simulation training, and a metrics system to assess the proficiency of the trainees before they performed surgical procedures in the operating theater.

Edinburgh Napier University streamlines long-distance learning with Cisco WebEX
• Geographically dispersed campus made in-person meetings costly and inconvenient.• Distance-learning programs in Malaysia, India, and China required dependable, user-friendly online tools to maximize interaction in collaborative workspaces.• Virtual learning environment required a separate sign-in process, resulting in a significant administrative burden for IT staff and limited adoption of collaboration technology.

8x increased productivity with VKS
Before VKS, a teacher would spend a lot of time showing a group of 22 students how to build a set of stairs within a semester of 120 hours. Along with not leaving the teacher much time to provide one-on-one support for each student to properly learn carpentry, it also left a considerable amount of room for error. Key information would be misinterpreted or lost as the class was taught in the typical show-and-tell way.

Scalable IoT Empowering GreenFlex's Sustainable Growth
GreenFlex, a company that supports sustainable development, decarbonization, and energy efficiency, faced several challenges in its quest to expand its business. The company needed to deploy a robust and sustainable IoT technology to support its growth. It was crucial for them to monitor and control devices at customer sites in a safe and reliable manner. They also needed to integrate devices across a range of communication protocols and gather and act on data to meet efficiency targets. GreenFlex had previously built IoT capabilities into its digital platform, GreenFlexIQ, to monitor and manage customer sites remotely. However, they soon realized that they needed a new platform to support their ambitions. They needed a platform that could scale to connect more devices for production management and make it easier for the operations team to manage devices in the field.
