UDOO
UDOO is a single-board computer with an integrated Arduino Due compatible microcontroller, designed for computer science education, the world of Makers and the Internet of Things. The product was launched on Kickstarter in April 2013, reaching wide consensus. "The product line involves three single board computers – UDOO QUAD/DUAL (2013), UDOO NEO (2015), UDOO X86 (2016) – that differ over various aspects, plus the UDOO BLU and the set of UDOO BRICKS."

Zero Energy Buildings Concept-Definition Review for Latin America
In recent decades, European countries have developed concepts, definitions, and construction technologies for Zero Energy Building (ZEB) that are effective and correspond to their specific climates. Latin American countries are still trying to find adequate solutions which respond to the local climatic, cultural, social, technical, and economic context. As such, this paper aims to establish the basis of the minimum energy efficiency and the renewable threshold for the definition of ZEB in order to better understand the application in Panama, based on assessing the energy regulations implemented in Panama. To achieve this aim, a review concentrated on the concept-definition and implementation adopted by Latin American countries is presented first before the paper converges into defining a framework for application in Panama. Finally, a case-study-based theoretical framework proposing a ZEB definition for Panama is discussed. The results of this study showed a net primary energy balance, of which the range falls into a plus energy building definition, indicating that all of the cases studied could supply their electricity needs using Photovoltaic generation. All dwellings studied have the potential to become a plus energy building, depending on the available roof surface area. Finally, a strengths, weaknesses, opportunities and threats analysis is presented in order to assess and support the introduction of such a ZEB definition and framework.

Bluetooth Low Energy Beacon
Bluetooth beacons are hardware transmitters - a class of Bluetooth low energy (LE) devices that broadcast their identifier to nearby portable electronic devices. The technology enables smartphones, tablets and other devices to perform actions when in close proximity to a beacon. Bluetooth beacons use Bluetooth low energy proximity sensing to transmit a universally unique identifier picked up by a compatible app or operating system. The identifier and several bytes sent with it can be used to determine the device's physical location, track customers, or trigger a location-based action on the device such as a check-in on social media or a push notification. One application is distributing messages at a specific Point of Interest, for example a store, a bus stop, a room or a more specific location like a piece of furniture or a vending machine. This is similar to previously used geopush technology based on GPS, but with a much reduced impact on battery life and much extended precision. Another application is an indoor positioning system, which helps smartphones determine their approximate location or context. With the help of a Bluetooth beacon, a smartphone's software can approximately find its relative location to a Bluetooth beacon in a store. Brick and mortar retail stores use the beacons for mobile commerce, offering customers special deals through mobile marketing, and can enable mobile payments through point of sale systems. Bluetooth beacons differ from some other location-based technologies as the broadcasting device (beacon) is only a 1-way transmitter to the receiving smartphone or receiving device, and necessitates a specific app installed on the device to interact with the beacons. This ensures that only the installed app (not the Bluetooth beacon transmitter) can track users, potentially against their will, as they passively walk around the transmitters. Bluetooth beacon transmitters come in a variety of form factors, including small coin cell devices, USB sticks, and generic Bluetooth 4.0 capable USB dongles.

Liquid Metal Droplets
Droplets exist widely in nature and play an extremely important role in a broad variety of industrial processes. Typical droplets, including water and oil droplets, have received extensive attention and research, however their single properties still cannot meet diverse needs. Fortunately, liquid metal droplets emerging possess outstanding properties, including large surface tension, excellent electrical and thermal conductivity, convenient chemical processing, easy transition between liquid and solid phase state, and large-scale deformability and so on. More interestingly, liquid metal droplets with unique features can respond to external factors including electronic field, magnetic field, acoustic field, chemical field, temperature and light, exhibiting extraordinary intelligent response characteristics.

Navy Mark IV
The Mercury space suit (or Navy Mark IV) was a full-body, high-altitude pressure suit originally developed by the B.F. Goodrich Company and the U.S. Navy for pilots of high-altitude fighter aircraft. It is best known for its role as the spacesuit worn for all manned Project Mercury spaceflights. The MK IV Full Pressure Suit ensemble was also used extensively by the US Navy from about 1959 through the early 1970s in aircraft such as the F-4 Phantom, A-3/A-5/RA-5C Vigilante, and F-8 Crusader.

Eryx (Missile)
Eryx is a short-range portable SACLOS-based wire-guided anti-tank missile (ATGM) produced by European company MBDA. It is used by several countries, including the Canadian Army, French, and Norwegian armies. The weapon can also be used against bunkers and pillboxes. It also has some capability in the anti aircraft role to bring down low flying helicopters, due to its wire-guided system. An agreement was reached in 1989 between the French and Canadian governments to co-produce the Eryx missile system. It entered service in 1994.

Field-emission Display
A field-emission display (FED) is a flat panel display technology that uses large-area field electron emission sources to provide electrons that strike colored phosphor to produce a color image. In a general sense, an FED consists of a matrix of cathode ray tubes, each tube producing a single sub-pixel, grouped in threes to form red-green-blue (RGB) pixels. FEDs combine the advantages of CRTs, namely their high contrast levels and very fast response times, with the packaging advantages of LCD and other flat-panel technologies. They also offer the possibility of requiring less power, about half that of an LCD system. Sony was the major proponent of the FED design and put considerable research and development effort into the system during the 2000s, planning mass production in 2009. Sony's FED efforts started winding down in 2009, as LCD became the dominant flat-panel technology. In January 2010, AU Optronics announced that it acquired essential FED assets from Sony and intends to continue development of the technology. (As of 2016), no large-scale commercial FED production has been undertaken. FEDs can also be made transparent. FEDs are closely related to another developing display technology, the surface-conduction electron-emitter display (SED), differing primarily in details of the electron-emission system.

Collaborative Learning
Collaborative learning is an exchange of ideas that enables and improves the interaction between two students (student–student) coping with the learning material on a network. When somebody imagine individuals seemingly completely focused on the screens and keyboards of their devices, people most frequently have a preconception that they are using those learning devices by themselves. However, such images of individual learning accompanied by electronic tools frequently do not reflect the hidden reality. In reality, students often use their computers to interact with others, and it is frequently their peers whom they interact with. These ideas arise from learning technology known as collaborative learning. Collaborative learning principles arise from a well-established approach to education, have a specific meaning and are specifically applied in practice.
