Abstract
A method for detecting the location of a gas leak 22 in buried utility gas pipes 12 by measuring the presence of a gas 18 below or above the ground surface 14 above the pipe 12 is improved by injecting a tracer gas 18 which is lighter than air into the utility gas 26 within the pipe 12 and by using a gas detector 28 having a higher sensitivity to the tracer gas 18 than to the utility gas 26 for pin-pointing the leak position 22.
Claims45
A computer-implemented method for evaluating the risk of a patient's tardy arrival for a scheduled appointment at a time at a health service center, the method comprising:
- obtaining at least a first tardiness risk factor and a second tardiness risk factor for the patient for the scheduled appointment;
- obtaining, from a computer memory device and with the aid of a processor, a first quantified tardiness risk value for the first tardiness risk factor and a second quantified tardiness risk value for the second tardiness risk factor;
- and
- combining, according to an algorithm and with the aid of a processor, the first quantified tardiness risk value and the second quantified tardiness risk value, to generate a total tardiness risk value.
A method of managing a patient's arrival at a health service center, the method comprising receiving by a health service center computer system information indicating that a patient has brought an NFC-enabled device into close proximity with an NFC tag in a display in the health service center.
A method of managing a patient's arrival at a health service center, the method comprising receiving by a health service center computer system information indicating that a computing device maintained by the patient is within a selected distance of the health service center.
