Bluetooth® beacons enable proximity-based, contextual awareness using simply a smartphone with applications. Wireless proximity detection technology is not new, but with Bluetooth Low Energy's features, beacons can be designed for retail customers, business loyalty programs, industrial asset monitoring, and more.   Beacon Basics In general terms, a beacon is a small, battery-powered, wireless device that uses Bluetooth low energy technology (Bluetooth Smart) to advertise its presence ...
Bio-patch solutions are sensors worn on the body to enable continuous and semi-continuous monitoring of physiological and psychological parameters without tethering the patient or athlete to a wired hub. Bio-patch sensor data is transmitted wirelessly to a gateway to enable patients to self-monitor or healthcare professionals to remotely monitor vital information. The disposable nature of bio-patches also helps meet patient safety requirements in hospitals due to the limitation of onetime-use. T ...
The Internet of Thing (IoT) is supposed to mean the convenient interconnectivity of our devices to the internet. But the security infrastructure for our smart devices has not yet caught up. We are becoming ever more vulnerable to the malicious intentions of black hatters.   It’s no secret security has long been a concern regarding Internet of Things (IoT) technology. Back during its early emergence, a study conducted by HP researchers found 70 percent of IoT devices were vulnerable ...
Acceleration, vibration, shock, tilt, and rotation—all except rotation are actually different manifestations of acceleration over different periods of time. However, as humans we don’t intuitively relate to these motion senses as variations on acceleration/deceleration. Considering each mode separately helps in envisioning more possibilities.   Acceleration (including translational movement) measures the change in velocity in a unit of time. Velocity is expressed in meters per ...
DARPA’s new AI radio Grant Challenge seeks to develop wireless communication that makes better use of the congested electromagnetic spectrum. The result could mean no more buffering, even if you are watching the new Star Trek film on your very old smartphone. (via DARPA)   DARPA just released the details of its 2017 Grand Challenge, which will facilitate the development of a machine-learning radio system that finds a creative way to work around congested wireless airways. On its webs ...
