Interesting if true. However, one needs to note that this is a news report
based on a an ex-parte filing (required by the Sunshine Act) of a Philips
meeting with a single Commissioner. Philips is required to report it.
It's the first time I can ever remember a news item about an ex-parte filing.
It is not them 1)actually proving it or even 2)showing the device to the
Commission and most importantly 3) letting the Commission testing the device.
