Recall mechanism for a pressure gauge
First Claim
Patent Images
1. A pressure gauge comprising:
- a housing having an inlet port for receiving fluid pressure of an object to be measured;
a sensor in communication with said inlet port for providing a value of said fluid pressure present at said inlet port;
a memory for storing said value; and
an actuator capable in response to actuation in a first mode for providing an audible output indicative of a pressure value stored in said memory prior to said actuation.

10. A handheld tire pressure gauge comprising:
-
a housing conforming to the hand of a user;
an inlet port formed on said housing for connecting to an object to receive air pressure of the object for measurement;
a sensor contained within said housing and in communication with said inlet port for determining the air pressure value associated with said object;
a memory for storing said value;
a user activatable area on said housing for generating a signal to a processor to retrieve said stored value from memory, said processor operable for providing an audible output indicative of said retrieved value. - View Dependent Claims (11, 12, 13, 14, 15)

17. A hand-held pressure gauge comprising:
-
a housing conforming to the hand of a user;
an inlet port at a first end of said housing for connecting to an object to receive air pressure of the object for measurement;
a sensor contained within said housing and in communication with said inlet port for determining the air pressure value associated with said object;
means responsive to said sensor for storing a parameter indicative of said measured value in memory and for providing both a visual display and audible utterance of said measured value to a user upon connection with said object;
means formed on said housing and responsive to subsequent user activation for recalling from said memory said last stored value and for outputting said audible utterance of said measured value.
