Four engineering students at MIT have developed a thermoelectric bracelet designed to help wearers maintain a comfortable body temperature. Resembling a wristwatch, the invention, known as Wristify, monitors air and skin temperature and sends pulses of hot or cold waveforms to the wrist when needed to help the wearer maintain thermal comfort. A custom copper-alloy-based heat … [Read more...]
Waterproof Tablet Computer Features Cooling Fan
Electronics manufacturer Fujitsu has released a unique new tablet computer capable of operating underwater while using a cooling fan to pump heat away from sensitive internal circuitry. The Arrows Tab QH77/M is 2-in-1 computer that can be used both as a clamshell notebook computer and as a tablet computer when the display unit is detached. The casing houses an Intel Core … [Read more...]
Thermal Connectors Improve PCB Assembly Heat Dissipation
TEM Products Inc., a manufacturer of mechanical components for electro-mechanical assembly, has released its new patent-pending PowerPeg thermal connectors. Designed for attachment to an external dissipater, the new PowerPeg thermal connectors offer significantly improved thermal conductivity compared to traditional PCB heat spreading methods by allowing heat to dissipate more … [Read more...]
