Samsung Patents Fat-Measuring Phone

  • PDF

Will health-related functionality be the killer app in the next generation of mobile devices? Samsung certainly hopes that will be the case as it patents a means of measuring body fat through smartphone sensors.

Samsung fat sensorThe patent, named "Method and Apparatus for Measuring Body Fat Using Mobile Device," describes a number of different sensors the company can integrate in devices. One is similar to the heart rate sensors already found in a number of Samsung smartphones (one simply holds a finger over the sensor to get a reading), while another involves gripping the device with both hands and moving one's arms up and down.

Mobile Processors Reach 10 Cores

  • PDF

MediaTek announces an industry first with the Helio X20, a system-on-a-chip (SoC) for smartphone and tablet use packing 10 cores on a single die, all connected with the so-called MediaTek Coherent System Interconnect (MCSI).

Helio X20The 10 cores are arranged in 3 clusters-- two Cortex-A725 cores clocked at 2.5GHz, four Cortex-A53s clocked at 2GHz and four Cortex-A53s clocked at 1.4GHz. The arrangement is compared to a car with 3 gears allowing for fuel efficiency across different terrains, since the low-power cores can handle non-demanding tasks while the 2.5GHz cluster takes care of bigger jobs.

The company also says the grouping allows for power savings of up to 30% off a standard ARM "big.little" implementation.

Butterfly Wings: The Key to Glare-Free Displays?

  • PDF

They say the flap of a butterfly's wings can cause a hurricane on the other side of the world, but the wings of a particular species of butterfly might actually be key to the glare-free displays of the future.

Glasswing butterflyThe butterfly in question is the glasswing butterfly, a Central American species famous for having transparent, glass-like (thus the name) wings. Karlsruhe Institute of Technology (KIT) researchers say these wings have very low reflection (around 2-5%) of visible, infrared and ultraviolet light-- a survival adaptation for the insect, but an inspiration for the creation of low-reflection surfaces.

For the curious, a flat glass plane has a reflection of anything from 8% to 100%.
