UnLoc Tehcnology Uses Invisible Landmarks to Improve Indoor GPS Accuracy

Engineers have been searching for a successful indoor GPS application. Illustration by Archana Gowda.

GPS has been a very useful technology for positioning users in an outdoor environment. However, telecommunication researchers have not been able to attain GPS-like accuracy indoors. In the last few years,companies like Google, Microsoft, Qualcomm and Apple have focused on indoor localization. Research teams at universities also have attacked the problem. Practical solutions are converging, and a localization application is expected to be in the market soon.

Big Surprise: Smartphone Owners Want Bigger Screens

According to research by Strategy Analytics, smartphone owners in the US and UK prefer device screens in the 4″ to 4.5″ range, as long as the device is also thin. Almost 90% of existing smartphone owners surveyed chose a prototype smartphone with a display larger than their current device. This trend is driven by increased mobile web browsing capability, and engaging video and gaming experiences. However, in order for smartphone owners to adopt larger devices, it is important for handset manufacturers to ensure that mobile devices are not too heavy and that the devices remain thin enough for purses and pockets.

Imec, Holst Centre, TASS Develop Electrocardiogram App for Android

Imec and Holst Centre, together with TASS software professionals have developed a mobile heart monitoring system that allows to view your electrocardiogram on an Android mobile phone. The innovation is a low-power interface that transmits signals from a wireless ECG (electrocardiogram or heart monitoring)-sensor system to an Android mobile phone. With this interface, imec, Holst Centre and TASS are the first to demonstrate a complete Body Area Network (BAN) connected to a mobile phone enabling reliable long-term ambulatory monitoring of various health parameters such as cardiac performance (ECG), brain activity (EEG), muscle activity (EMG), etc. The system will be demonstrated at the Wireless Health Conference in San Diego (US, October 5-7).
