AOI inspectionAutomated optical inspection (AOI) is an automated visual inspection of printed circuit board (PCB) manufacture where a camera autonomously scans the device under test for both catastrophic failure (e.g. missing component) and quality defects (e.g. fillet size or shape or component skew). It is commonly used because it is a non-contact test method.

This is a smart bio-disc system for performing low-cost nucleic acid screening of tuberculosis (TB) from sputum samples. Low-cost point-of-care genotyping devices offering rapid screening of infectious disease such as TB, hence minimizing the chance of transmission, will lead to drastic cost savings on treatment. An important technological breakthrough of our &quot;Intelligent Bio-disc Platform&quot; (IBP) comes from the delivery of electrical power to the bio-disc.
 
  This has overcome a major bottleneck in existing lab-on-a-disc designs because many previously impossible yet necessary functionalities such as flow metering, sample heating and real-time signal detection, may now be realized with the supply of electricity. 
  The use of centrifugal actuation offers many advantages including low device complexity, limitless parallelization and availability of actuation force anywhere on the disc.

Skin Firming &amp; Lifting Scientifically Proven: Multi-Dimensional Aesthetic Enhancement Smoother Texture &amp; Touch: Clinical studies show that after 12 systematic sessions, participants experienced up to 93%* visible improvement in the smoothness of cellulite (orange-peel skin).Restored Skin Density: Through natural activation of fibroblasts, after 12 sessions, 92%* of participants reported significant improvement in skin firmness, effectively tightening and optimising loose contours.Immediate Decompression &amp; Lightness: Participants reported an average 50%* reduction in leg fatigue and heaviness sensation after the first session.Refined Local Contours: Combined with overall metabolic optimisation, after 12 sessions, participants observed a localised circumference reduction of up to 5.8 cm* (e.g., waist circumference).*Note: All data cited from the 2024 BeScored clinical study report. The figures demonstrate the physiological responses of the technology. Individual results may vary depending on constitution, age, and lifestyle habits. Non-Invasive Cellular Activation Aesthetics Why does skin lose its elasticity? Skin aging is not only due to natural factors but is also closely related to photoaging, life stress, and slowed circulation. The key cells responsible for maintaining elasticity — fibroblasts — produce less collagen and elastin over time, leading to sagging and visible texture changes.BTO’s “Natural Activation” Philosophy: Our patented physical stimulation technology does not rely on external fillers. Instead, it uses unique mechanical energy to perform “cellular fitness” on deep tissues. This naturally activates fibroblast activity, encouraging the production of endogenous collagen and hyaluronic acid.This approach is traceless, requires no downtime, and aims to reboot the skin’s self-healing cycle, helping maintain long-lasting youthful texture and firmness.
