Patent attributes
A tire pressure gauge for attachment to a valve stem includes a wall defining a chamber having a first port adapted to sealingly engage a valve stem, a probe being mounted in the first port so as to open a valve of a valve stem sealingly engaged by the first port, a pressure sensor in the chamber, a memory, a display physically supported on the device, a processor being operatively coupled to said display, pressure sensor and memory; and code being stored in the memory and operable by the processor to: retrieve at least one value indicative of a first threshold tire pressure from the memory, determine a pressure sensed by the pressure sensor, and, cause the display to present information indicative of a relative value of the sensed value to the first threshold tire pressure.
