New form BorgCo for the Winter season, a pair of warm, comfortable snow boots with a calibrated microwave or ultrasonic measuring system integrated into the sole or heel.
They are activated and adjusted by a handheld wireless remote control.
The wearer inputs their mass. Based on the current temperature,
the mass value, and the known strength of sheet ice, plus a "factor of safety", the system sounds an alert when the wearer first steps onto ice with liquid water beneath it, and an alarm when the thickness diminishes to the point where its strength is less than the preset safety margin.

Why should the wearer have to input their mass? Just incorporate a load plate to weigh in use. |
|
| |
With the microwave or ultrasound it's going to be ridiculously expensive already anyways, won't add much cost. |

I love this and would bun twice if allowed. (++) |
|
| |
Is the sensor really limited to detecting the thickness directly beneath the boot? Can't it interpolate from the oblique signals, so as to infer the thinning of the ice? |
|
| |
Can it be fitted with ejection rockets in case of the ice cracking? |

"It's OK. I have these special boots that send powerful
microwaves into the ice to measure its thickness. The
display says it's seven inches thick. No...wait....six
inches....no, hang on....five..." |

// warns you before you step on weak ice // |
|

Hence the "safety margin" calculation ... |
