1. A tire pressure and temperature measuring device comprising:
- a housing comprising a first portion and a second portion, the second portion of the housing defining a handle configured to be held by a hand of a user for supporting the first portion of the housing;
a nozzle arranged on a first outer surface of the first portion of the housing;
a pressure sensor within the first portion of the housing and associated with the nozzle;
a temperature sensor, for measuring a temperature of a surface of a tire, within the first portion of the housing, the temperature sensor aligned with a first opening on the first outer surface of the first portion of the housing;
an optical pointer, aligned with a second opening on the first outer surface of the first portion of the housing, and arranged to illuminate a portion of the surface of the tire during measurement of the temperature of the surface of the tire by the temperature sensor;
a display arranged on a second outer surface of the first portion of the housing for viewing by the user while holding the handle during measurement of the temperature of the surface of the tire by the temperature sensor; and
a processor arranged within the housing and responsive to outputs of the pressure sensor and the temperature sensor, the processor configured to output a value indicative of a measured tire pressure and a value indicative of a measured tire temperature to the display.

Abstract
A system for measuring tire pressure and temperature including a pressure sensor, a temperature sensor, a processor responsive to an output of the pressure sensor and the temperature sensor, and a display. The processor is configured to output a value on the display indicative of a measured tire pressure and an indication of measured tire temperature, wherein the indication of measured tire temperature comprises an indication of the result of a comparison between the measured tire temperature and a predetermined temperature value.

12. A method of detecting and displaying tire temperature and pressure with a hand-held measuring device, comprising:
-
illuminating an area of a tire with an optical pointer radiating from a first outer surface of the measuring device; measuring the temperature of the tire proximate the illuminated area with a temperature sensor having a sensing axis extending from the first outer surface of the measuring device; receiving by a processor of the measuring device data indicative of the measured tire temperature from the temperature sensor; measuring tire pressure by providing, via a nozzle arranged on the first outer surface of the measuring device and engaged with a valve of the tire, air from the tire to a pressure sensor of the measuring device; receiving by the processor data indicative of the measured tire pressure from the pressure sensor; and outputting from the processor to a display a value indicative of a measured tire pressure and a value indicative of a measured tire temperature. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
