Information Processing Consultants Ltd

Proactive Individual Caring System(PICS) is an award-wining software solution designed for elderly Homes and Homes for under-privileged individuals who need special cares in their daily lives. PICS is developed since 2016 by IPc and has been implemented in many Homes in Hong Kong and Macao since its launch in subsequent year. PICS was awarded silver medal in ICT2018. It composes of two main modules, namely, Homes Administration and Drug Administration. These two modules are seamlessly integrated to form a comprehensive Individual Caring System for Homes aiming at proactively avoiding occurrence of adverse incidence.  Before resident admits the Home, pre-assessment is administered so that preparatory work is ready. Home administration includes creating resident personal and clinical profiles, and establishing individual caring plan (ICP) for each resident. The ICP records vital signs, wound positions, dentition, and caring schedule. This schedule serves as reminder of events to be alarmed in carrying out the daily routines such as taking drugs, measuring vital signs like blood pressure, blood sugar level, blood oxygen level, and pulse. These vital signs can be transmitted to PICS via Bluetooth provided these instruments are verified by IPc technical team.  Drug administration includes inventory of drug dispensary. This in-house pharmacy dispenses drug to resident according the prescription of medical officer (MO). PICS alerts adverse drug reactions (if any) that may occur when drugs are dispensed to resident. Nurses and care takers use Android tablet PC while they are administering drugs to residents. The tablet PC displays the photo of the resident along with the one-to-one photo of each drug as part of the three-verification-five-check paradigm in drug dispensing. The drugs dispensed are recorded at spot as electronic medical administration records (eMAR). MAR is mandated by Government of Hong Kong and Macao.  PICS also includes a module for in-house/visiting MOs to record diagnosis and prescribe at spot the drugs for residents. These prescriptions immediately appear in the in-house pharmacy. This process accelerates the dispensing time and ease the work of MOs. Drug administration module can be extended to drug packaging which greatly relieves the burden of nurses in Homes as drugs are packed per each in-taking of drug. Currently, PICS seamlessly interfaces with JVM and Yuyama drug packaging machines.  IPc wholly-owns the intellectual property of PICS. Should customisation, such as community drug centre, be mandated, IPc has the rights and capability in customizing new features for Homes.   To promote PICS so that total cost of ownership is kept to the minimal, PICS is available as Software as a Service (SaaS) approach in implementation. Homes just pay a monthly subscription fee instead of paying huge one-time license fee which has included computer servers and software and saved expenses of in-house IT staff.

Wenzhou Lynns Design Co. Limited

At JLX EYEWEAR, we've redefined what's possible in 3D printed eyewear finishing. Our proprietary post-processing technology transforms raw printed frames into luxurious wearable art, achieving a matte-shiny surface quality that sets new industry standards. These eight detailed close-ups reveal the meticulous craftsmanship behind every JLX EYEWEAR private label piece - notice how light dances across the perfectly balanced matte base while subtle luminous highlights accentuate each curve and contour.  Our multi-stage finishing process begins with precision mechanical polishing to eliminate all visible layer lines, followed by specialized chemical treatments that create the perfect matte foundation. The frames then undergo our signature coating application, where nano-level particles are carefully layered to build depth and dimension into the surface. The final hand-finishing stage ensures every millimeter meets our exacting standards, resulting in a tactile experience that feels as premium as traditional luxury materials.      What makes our finishing truly revolutionary is how it maintains structural integrity while achieving visual perfection. The matte surface provides sophisticated understatement, while the controlled shine adds dynamic energy that changes with movement and lighting. This proprietary technique allows for unprecedented consistency across entire collections - whether producing fifty or five hundred frames, each piece maintains identical surface characteristics.    For brands partnering with JLX EYEWEAR, this finishing technology opens new creative possibilities. Our process works seamlessly with complex geometric designs that would be impossible to finish conventionally, while offering customizable sheen levels from soft satin to high-contrast matte/gloss combinations. The result is eyewear that feels substantial yet lightweight, looks handcrafted yet technologically advanced.   Explore the future of 3D printed eyewear finishing at www.jeffreyleungeyeweardesign.com and discover how our surface technology can elevate your private label collection.  #JLXFinishing #MattePerfection#3DPrintedLuxury#EyewearInnovation#SurfaceTechnology#LuxuryFinishes#PrivateLabelExcellence#FutureOfEyewear
