Provided is a computer-implemented method for preforming negative pressure testing, also known as an inflow test. In the method, a non-transitive computer readable medium storing a pressure analysis program for analysis of pressure data is provided that when executed, causes an information processing apparatus connected to an image display screen, to receive at least one of a plurality of inputs from a user, receive a plurality of pressure values from a sensor filter at least a subset of the plurality of pressure values, select one of a plurality of negative pressure testing models; run the filtered subset of pressure values through the selected negative pressure testing model; and store the values generated by the negative pressure testing model.

A pressure sensing device includes a pressure signal receiver configured to receive an analog pressure signal from a pressure sensor, a converter configured to convert the analog pressure signal to a digital pressure signal, and a processor configured to convert a pressure value of the digital pressure signal to a bit value corresponding to the pressure value and output the bit value. The processor is configured to convert the pressure value to a first bit value by a first bit resolution in response to the pressure value being included in a first pressure interval, and convert the pressure value to a second bit value by a second bit resolution in response to the pressure value being included in a second pressure interval. The second pressure interval is a pressure interval greater than the first pressure interval, and the first bit resolution is greater than the second bit resolution.

A method of determining the health of a tire on a vehicle includes determining a total number of tire inflation events that have occurred due to a loss of tire pressure. A rate in which the tire inflation events have occurred is determined based on the total number of tire inflation events over a predetermined period of time. The health of a tire is determined by comparing the rate in which tire inflation events have occurred to a threshold rate.
