Taiwan has the highest rate of dialysis in the world! Keeping dialysis machines functioning properly is the top priority for reducing risks

According to the latest annual report released by the US Renal Data System (USRDS), Taiwan has the highest dialysis rate in the world. In 2018, acute and chronic kidney disease patients spent NT$51.378 billion on health insurance, and the number of dialysis patients in the country surged past 90,000!

When kidneys function no longer, replacing kidney function either through transplantation or dialysis is necessary, with about 90% of patients choosing hemodialysis (commonly referred to as 'dialysis'); Patients generally require treatment three times a week for 4-5 hours per session at specific medical facilities (hemodialysis centers, commonly known as 'dialysis centers'), which is a high-risk medical procedure.

During hemodialysis at the centers, unexpected events directly affect patient medical safety and quality of treatment, consuming medical resources and manpower to resolve or correct. Reducing these incidents during hemodialysis is a major requirement for these centers. The two most common incidents involve dialysis equipment problems and patient complications, with most technical issues attributed to the hemodialysis machines.

Hemodialysis machines are structurally complex and prone to safety hazards

The design of a hemodialysis machine is intricate and precise, featuring an integration of fluid mechanics, electronics, mechanics, and optics in its extracorporeal circulation system. Due to long operating hours, the machine is susceptible to thermal and chemical corrosion, causing wear and tear and potentially impairing the entire dialysis system's operational performance, with multiple risks and safety hazards.

When a hemodialysis machine experiences an 'event,' whether minor or major, reactive maintenance is triggered. Not only do patients have to switch to an alternate bed, but during the approximately 2 to 3 days of maintenance downtime, the affected beds become unavailable, thereby reducing the number of available beds and causing scheduling issues for already booked patients.

Any 'event' involving hemodialysis machines is a significant concern for centers, thus improving the equipment utilization rate of these machines is a pressing issue!

Using AI for Predictive Maintenance to Improve Utilization Rates of Hemodialysis Machines

Development Workflow

By utilizing big data and AI predictive framework to adopt a proactive 'predictive maintenance' approach instead of a reactive 'fix-on-failure' approach, it helps reduce the occurrence of irregular incidents, improving the availability of hemodialysis machines and thereby hoping to handle their malfunctions better, conserving medical resources, manpower, and time, while improving treatment quality and protecting patient life safety.

Through AI predictions, maintenance of hemodialysis machines can be categorized as 'Predictive Maintenance' and 'Real-Time Fault Diagnosis.' 'Predictive Maintenance' refers to regular checks of the machine's status using big data and an AI prediction model during the daily pre-heating of the machines, delivering health status alerts if unhealthy trends in parameters are detected. 'Real-Time Fault Diagnosis' involves analyzing data and equipment status during dialysis using the AI model to ascertain if predictive maintenance is necessary; when an issue arises, it can be diagnosed and non-major events immediately resolved.

With an innovative service mode, promoted across dialysis centers in Taiwan or the Asia region

The AI predictive maintenance model can reduce abnormal events during dialysis, optimize on-site resources, increase available hemodialysis bed numbers, and consequently provide further safety for patients. For 'patients,' it reduces the incidence of mishaps causing harm and discomfort; for 'medical staff,' it enhances the ability to handle such events easily, improving job satisfaction and quality; and for 'hospitals,' it fosters improved medical quality, patient satisfaction, and cost savings, while minimizing medical disputes.

'Increasing the Availability of Hemodialysis Equipment' is crucial for dialysis centers. AI predictive maintenance as an innovative service model can be promoted extensively among dialysis centers with large patient volumes across Taiwan or Asia, also integrating individual dialysis statuses, including backend maintenance, dispatching, and parts inventories, planning a new cloud service operation model.

properly allocate and distribute it to needy households, thus aiding local vulnerable families55Food banks at various locations collect daily donations from wholesale stores, intermediaries, retailers, manufacturers, and even benevolent individuals from all over Taiwan These places also rescue about-to-be-discarded edible materials, properly sort them, and distribute to needy households, assisting local vulnerable populations However, each location requires significant human and volunteer resources to manage daily operations using traditional methods of communication with non-profit organizations and donors After receiving donations, these resources are then allocated to needy families or individuals There is a potential issue of uneven distribution of resources due to a lack of digitalization and integrated information management in these processes Warehouse and Transportation Centers and Mini Food Banks Distributing Resources to the Disadvantaged The location under

Kaohsiung Charitable Organizations Association Challenges in Labor and Food Resource Management Facing the needs of a large number of economically disadvantaged families, the management of the 'Food Bank-Warehouse and Transportation Center' is particularly critical During procurement, tasks such as sorting, purging, and bookkeeping must be performed, while during shipment, food resource needs suggested by social workers must be followed These activities rely on manual judgment and accumulated experience Many volunteers involved are elderly and have limited physical strength, making warehouse tasks physically demanding and recruitment challenging If a large batch of food resources arrives, space and manpower are consumed in sorting and inventory management, raising concerns about the effective use of resources and turnover rate This highlights the challenge of scaling up food bank services while lacking corresponding labor and material management systems At the same time, food bank resources come from various donations, thus they vary greatly in type, shelf life, standards, and quantity Volunteers at mini food banks, mostly also elderly, must handle multiple responsibilities such as case services, food resource management,resource allocation, and resource development Sometimes they must also explain and accept immediate, large quantities of specific

HRT Technology Improves Production Efficiency by 20% Through AOI Detection of Defects in VCSEL Packaging

In 2017, the launch of the iPhone X made 3D sensor technology used in Face ID highly popular, which drove the development of VCSEL, a core component in the 3D sensor module In the detection of defects in incoming packaged VCSEL, the use of AI inference models can solve the industry's issue with low yield and improve reliability to 95 VCSEL technology currently can be used in many applications and various end consumer markets, including robots, mobile devices, surveillance, drones, and ARVR VCSELs are a good solution in applications that require high-speed modulation capabilities, such as cameras and biometrics VCSEL technology has a wide range ofnbsp applications, including in drones Pictured Zoyi Technology's Agricultural Drone VCSEL technology has a wide range of applications, AI technology assists in defect detection HRT Technology stated that the packaged VCSEL market is also facing strong price competition from competitors, and needs to further reduce costs and enhance product competitiveness One of the key problems is the replacement of glass lens with epoxy resin lens The production of traditional glass lenses has high yield, but the cost is higher than that of epoxy resin lenses Due to the cutting process of epoxy resin, the side wall of cutting lines can easily have rough edges, causing it to be oversized The release of stress caused by heat during the mounting process will directly cause the optical lens to break HRT Technology pointed out that the incoming inspection of VCSEL epoxy resin lenses is very important Under the constraints of packaging space, the space for fitting the package and optical lens is limited Moreover, the optical lenses will be confined to a metal frame If the dimensional tolerances are properly controlled, stress release due to heat during mounting can easily cause the optical lens to break, resulting in a yield loss of up to 10 in the VCSEL package reliability verification, resulting in an increase in production costs In order to solve the problems above, HRT Technology hopes to use AI to monitor the size and appearance defects of epoxy resin components in the VCSEL epoxy resin lens incoming stage, verifying whether their dimensions meet specifications, whether the cutting edges are smooth, and whether there are any defects in their appearance Since traditional incoming material inspection requires a rough visual inspection by humans to distinguish the quality The problem of image collection needs to be solved first to successfully collect image data Therefore, HRT Technology first developed an Automated Optical Inspection AOI device, which includes X, Y, Z three-axis motion, high-resolution cameras, and related control software to automatically record images After collecting the image data, opencv aligns the test image and a normal image to determine differences between the two images, and then pixel mapping is used to compare the pixel area to complete initial screening Manual labeling is carried out according to the image classification above, including samples that are normal, have defects in appearance, or have different shape characteristics, and then algorithm training and verification is carried out Residual neural network ResNet or other related algorithms are used for deep learning to identify the quality of lenses Implementation of AOI inspection improves production efficiency by 20 and above Comparing the differences before and after the implementation of AI image inspection, the incoming VCSEL lens inspection before implementation only involved manual inspection of the appearance The lens is packaged on the VCSEL package that has completed die bonding After passing the general light up test, the final reliability test high temperature reflow is performed Failed samples go into the rework process However, after the implementation of AOI inspection, it can screen defective lenses sooner and reduce the cost of subsequent materials input, it can also reduce the need for rework due to failure, improving yield to 95 and above in the reliability verification This is expected to help companies reduce production costs by 10 and increase production efficiency by 20 and above The difference before and after implementing AI image detection HRT Technology pointed out that this technology is an AI application developed based on tiny images It uses deep learning algorithms to identify defects in the images The trained network automatically classifies image data to predetermined categories Defect categories can be determined through reference images, so cumbersome programming is not required In the industrial machine vision environment, deep learning is mainly used for classification tasks in applications, such as inspection of industrial products or identification of parts In the future, with the development of IoT wearable devices and the trend of energy saving, the size of optoelectronic components will continue to shrink This technology can be applied to the detection of defects in the appearance of other tiny optoelectronic components in the future
