Abstract

An improved system for the recording and display of barometric pressure information, comprising a timekeeper, barometric sensor, memory system, and display, integrated to form an instrument or horological complication for the display of the current barometric pressure and past pressure history by use of an animated display.

IPC Classes  ?

• G01L 7/20 - Measuring the steady or quasi-steady pressure of a fluid or a fluent solid material by mechanical or fluid pressure-sensitive elements using liquid as the pressure-sensitive medium, e.g. liquid-column gauges involving a closed chamber above the liquid level, the chamber being exhausted or housing low-pressure gas; Liquid barometers
• G01W 1/02 - Instruments for indicating weather conditions by measuring two or more variables, e.g. humidity, pressure, temperature, cloud cover or wind speed
• G01L 19/10 - Means for indicating or recording, e.g. for remote indication mechanical
