Tire pressure gauge
First Claim
1. A tire pressure gauge comprising:
- a chuck that is capable of engaging an air valve of a tire to detect tire pressure;
an arithmetic circuit coupled to the chuck and capable of computing a measured tire pressure value;
a display for digitally displaying the measured tire pressure value;
an audio output unit capable of aurally outputting a tire pressure warning voice message, if the measured tire pressure value approaches a limit value stored in the arithmetic circuit.

Abstract
A portable tire pressure gauge measures a value of tire pressure. The gauge may display the measured value digitally and may output the measured value aurally. The tire pressure gauge may also aurally output a verbal message warning the operator if the measured value approaches a limit value, e.g., if the measured value is below a lower limit or above an upper limit. The limit values, or range of acceptable pressure values, may be set by the user and stored in the gauge. Further, a voice selection switch may be used to selectively turn on and off the voice output warning. Further still, in some examples, the voice warning may be provided in one of multiple foreign languages using the voice selection switch.

11. A method of indicating tire pressure, the method comprising:
-
detecting a tire pressure from a chuck engageable with an air valve of a tire; measuring the tire pressure from the detection of the tire pressure; displaying the measured tire pressure; determining if the measured tire pressure is outside a limit value; and aurally outputting a warning voice message, if the measured tire pressure is outside the limit value. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A tire pressure gauge comprising:
-
a chuck that is capable of engaging the air valve of a tire; means for detecting tire pressure through the chuck and measuring that pressure in selected measurement units; a display for digitally displaying the measured tire pressure; an audio output unit for aurally outputting the measured tire pressure in one of multiple different languages; a voice selection switch for selecting a language from the multiple different languages and for switching on or off the aural output, wherein the multiple different languages comprise more than two different languages; and a power supply for measuring and displaying the tire pressure. - View Dependent Claims (20)
