Many of us are familiar with navigation using Global Positioning System (GPS), however GPS does not work indoors. On the other hand, bluetooth technology provides an alternative means for indoor positioning and indoor navigation.

Heat exchangers are used to improve the efficiency of heating and cooling systems in domestic and industrial applications and can be found in heating, ventilation, air conditioning and refrigeration (HVAC) equipment, as well as chemical, oil and gas, and power plants, among others. Depending on the device and application, different types of heat exchanges are used. For example, heat sinks in laptops prevent overheating, heat pumps keep refrigerators cool and heat pipes of different size and configurations are used from laptops to commercial centralised air-conditioning systems.

More than two billion people lack access to clean and safe drinking water. Factors like water scarcity, urbanisation and climate change also continue to add pressures on the demand for water which is expected to grow.

Real-Time Location Systems (RTLS) are positioning technologies that identify and track the location of assets or people at any given time. These automated solutions reduce the need for manual tracking and make daily operations, such as inventory management and personnel tracking, more efficient. However, depending on the technologies deployed, there may be different requirements with regard to accuracy and range.

Enterprises around the world are progressively integrating automation and robotics in their processes. The same disruptive technologies are also developing and converging. One such growth trend is the combination of machine vision with robotics to add new capabilities and enable smart manufacturing.

One of the most common ways to harness solar energy is to install photovoltaic (PV) panels on residential or commercial building rooftops, or solar farms which can supply power on a larger scale. However, with limited land especially in dense urban cities, an alternative approach is to turn vertical building facades into solar producing panels, also known as building-integrated photovoltaics (BIPVs).

Customer insights are a way of uncovering new opportunities for businesses. Based on its customers’ feedback, Allalloy Dynaweld Pte Ltd (Allalloy), a Singapore SME providing welding solutions and consultancy services had identified a market need for better performance monitoring of its welding machines and welders. It was keen to work with suitable technology partners to co-develop an efficiency monitoring system to track the energy consumption of the welding machines as well as welders’ productivity.

Percutaneous Nephrolithotomy (PCNL) is a complicated process of removing large or complex kidney stones and typically carried out by senior surgeons. With the Percutaneous Access to Kidney Assist Device (PAKAD), an innovation developed by the team at the Institute of Technical Education (ITE), the surgery is set to become simpler, safer and shorter. The device uses precision engineering mechanisms to align the needle with the target, ensuring higher accuracy and reducing the risk of surgery complications and recovery periods.

There is a growing demand for point-of-care testing or bedside testing in the last few decades. It provides convenience to the patient and quicker results to the healthcare providers for faster clinical management decisions. The challenge is to keep it affordable and accessible.

The gold standard for perishable food: an unbroken cold chain

If you’re in Punggol and happen to be hungry, there’s a vending machine you can head to. But forget about snacks like candy bars and potato chips, this machine dispenses ready-to-eat, piping hot chili crab from restaurant chain, House of Seafood.

While some may worry about the texture and taste of the vacuum-sealed crabs, others are more concerned with how safe the meals are for consumption.
