Protects James Bond from Eavesdropping and Ordinary People against Burglary
The piezo elements can also be used to sense manipulation of a window, feeding the acoustic signal into an alarm system while the piezo elements installed inside the room can scare off the perpetrator with a shrieking sound. Software that evaluates the vibration spectrum of the windows prevents false alarms by recognizing rattling, wind buffeting etc.
If programmed accordingly, the piezo elements in windows can also be used to actively cancel out street noise and if you are a double–zero agent, you’ll appreciate the anti-eavesdropping option, keeping your secrets from the hands of the enemy.
HST srl is an Italian start-up company founded by Ph.D. researchers trained at Politecnico di Milano, now at the head of Soluzioni Ingegneria s.r.l, and local industrialists. It concentrates on structural vibration acoustics, where receptors are built into existing architectural structures, such as doors, windows or furniture. Passive structures are then transformed into active systems for sound generation as well as sound and vibration recording, for speech recognition systems, prediction of seismic events, and for active noise cancellation. HST obtained an international patent in 2012 and presented its market products for the first time in 2013.
