Just when you thought you’d heard, read and seen absolutely everything there is to about QR codes, along comes this little story to make you sputter in your corn flakes. Earlier this month, the craft-store chain Michael’s was hit with a lawsuit for the use of QR codes in its circulars by QR code company Neomedia, according to 2DCode.com. Um…and …

A method for measuring substantially spherical particles, such as dust. Two signals are formed, one of which is an approximately linear function of the particle concentration independently of the particle diameter and the second one is an approximately linear function of the particle diameter independently of the particle concentration. In order to obtain these signals the particles are illuminated with light in a direction different from their direction of flow. At least two detectors are arranged in such a way that the light in the beam path from the light source (3) to the first detector (6) is substantially only influenced by scattering and by light absorption of the particles and that the light in the beam path from the light source to the second detector (7) passes substantially only via reflections against the particles. The two signals are formed by definite relations between the d.c. voltage components of the output signals of the detectors and the average value of the squared R.M.S. value of the a.c. voltage component of the output signal from one of the detectors.

A wireless electronic scale essentially comprises a pair of wirelessly connected modules, a weight sensor pad and a display that would function like a bathroom scale. The weight sensor pad is placed on the floor and measures the user's weight and the display is wall mounted to display the information.

electronic tile implements variable colour and/or brightness and/or temperature. This tile is inserted in a system of several identical tiles which covers a surface. A special tile controls the system parameters such as colour, brightness, temperature, thus colouring and conditioning the surface and/or the environment at will. Every single tile and each sub-part of it can be indipendently controlled. The tile implements the above mentioned functionalities without any wiring. At least one tile has to be connected to the electrical supply.
