- 2015-06-30 A Closer Look: Secure your phone without passcodes
- Passcodes are outdated. They're a pain to use, and they aren't secure when they are based on easy-to-guess digits, such as a birth date or street address. Many people don't bother using them on phones, even though that means any thief can get instant access to email, banking apps and more. Fortunately, phone makers have started to come up with alternatives to passcodes.

- 2015-06-30 Dynamic calibration of pressure sensors using shock tube
- Scientists at NPL's Dynamic Pressure Sensor Facility have published a paper, Towards a shock tube method for the dynamic calibration of pressure sensors, in Philosophical Transactions of the Royal Society A.
The paper outlines the development of a plastic shock tube, working at 14 times the pressure of the atmosphere (1.4 MPa). The tube is made from PVC-U tubing and provides a low-cost, light and easily modifiable basis for research into the dynamic characterisation of pressure sensors. It provides pressure readings within a nanosecond- exceptionally quick for a mechanical process. - See Details

- 2015-06-29 Ultra-compact implantable image sensor using body channel communication
- An ultra-compact implantable image sensor using body channel communication has been demonstrated in Japan. The body channel approach allows the sensor-transmitter device to be much smaller and use less power than an RF wireless unit.
Fundamental limits
Interest in implantable medical sensors is on the rise as developments in established technologies and new concepts are making more and more applications feasible. One thing that all such sensors share is the need to be able to get the information they gather within the body, out of the body. - See Details

- 2015-06-29 Augmented reality helps in industrial troubleshooting
- At a "smart" factory, machines reveal a number of data about themselves. Sensors measuring temperature, rotating speed or vibrations provide valuable information on the state of a machine. On this basis, worn parts can be exchanged in due time. A software developed by the Institute of Telematics of Karlsruhe Institute of Technology (KIT) helps the maintenance staff allocate the information transmitted by the sensor in a wireless manner to the point of measurement in the camera image. The sensor data are imported into the latest camera shot of the real machine.
