2015 Create the Future Design Contest: Medical Category Winner

Smart X-ray Source Mark Eaton Stellarray Austin, TX Since the discovery of x-rays 110 years ago, affordable x-ray sources have all been point source x-ray tubes in which x-rays are generated at a single spot on an anode by a single electron beam accelerated at high voltage across a vacuum gap. Generation of x-rays from a single spot, even in rotating anode tubes, limits the flux they can deliver, because most of the e-beam energy will be absorbed in that spot.

2015 Create the Future Design Contest: Sustainable Technologies Category Winner

ECHY: Solar Lighting with Fiber Optics Stephanie Le Beuze ECHY Ile-de-France, France For many, artificial light has completely replaced natural light. Lighting can account for up to 50% of building electricity consumption, and up to 56% of energy bills in offices. Artificial light is not only costly for us and for the environment, but prevents us from using a natural and abundant resource: sunlight.

Thermally Conductive Adhesives Bring Specialized Solutions to Complex Design Challenges

With advances in epoxies, silicones, and other materials, manufacturers can find adhesives able to meet nearly any combination of requirements for thermal, environmental, and structural stability. Thermally conductive adhesives are uniquely qualified to meet the increasingly diverse requirements of advanced electronics systems. From their traditional use as fastening materials, adhesives find wide application in bonding and encapsulation in nearly every application segment, including military/aerospace, medical, automotive, and industrial, among others. In their traditional application in computer and communications systems, thermally conductive adhesives have long played a vital role at the chip level for die attach, at the PCB level for heat sink bonding, and at both the chip and board levels for all types of thermal management methods.

LED Lighting Enables Better Sleep and Wake Cycles

LED technology helps astronauts sleep and keeps gardens growing. Because NASA is planning for future visits to distant locations like Mars, the agency is researching how to grow plants in space. Live plants on space missions provide a nutritious food source and contribute to cleaning air in a spacecraft. When looking at how to best grow plants on space missions, NASA looked at high-intensity halogen lights, special UV bulbs, and light-emitting diodes (LEDs). By incorporating different LEDs on a single circuit board, the light can be changed and controlled to include or omit specific wavelengths of light, and at different times.

Product of the Month: November 2015

Honeywell, Minneapolis, MN, announced the Amplified Basic Pressure (ABP) sensors for small and low-power devices. The ABP sensors feature wet-media compatibility, as well as sleep mode and temperature output options, making them suitable for Internet of Things (IoT) applications. Measuring 8 x 7 millimeters, the sensors’ size enables engineers to save board space. The sensors feature a ±1.5 percent total error band (TEB), and can read pressure ranges from 60 mbar to 10 bar, 6 kPa to 1 MPa, and 1 psi to 150 psi. The sensors minimize the need for additional components, and are available in both analog and digital output I2C or SPI. Moisture sensitivity level of one allows unlimited shelf life when stored at <30 ºC/85% RH. Under most storage conditions, this allows the sensor to be soldered onto the PC board without concerns about solder joint quality due to aging of the sensor terminals.
