Method for processing information in a tire pressure monitoring system
InactiveUS6868358B2Improve utilizationAccurate detectionInflated body pressure measurementRegistering/indicating working of vehiclesEngineeringTire-pressure monitoring system
A method of processing information in a tire pressure monitoring system includes the steps of: establishing a reference temperature; determining a pressure warning threshold at the reference temperature; measuring gauge pressure and gauge temperature within a tire cavity; correcting the gauge pressure to a filtered pressure value at the reference temperature using the Ideal Gas Law; and comparing the filtered pressure value against the pressure warning threshold to determine the necessity for a warning signal. In an advanced form of the invention, the method includes determining a pressure leak rate; predicting the time interval that the filtered pressure value will cross the pressure warning threshold at the leak rate and generating progressive warnings to the driver over the time interval. Fuzzy logic is used to quantify the probability of a warning state for each data point, allow for measurement error; and report the state of maximum probability to minimize the occurrence of false warning. A warning utility function is derived based upon a combination of the filtered pressure and leak rate.

Arterial blood pressure monitoring devices, systems and methods using cardiogenic impedance signal
Provided herein are implantable systems, and methods for use therewith, for monitoring a patient's arterial blood pressure. Electrode(s) implanting within and / or on the patient's heart are used to obtain a cardiogenic impedance (CI) signal indicative of cardiac contractile activity. Additionally, a signal (e.g., PPG or IPG signal) indicative of changes in arterial blood volume remote from the patient's heart is obtained using a sensor or electrodes that are implanted remote from the patient's heart. One or more metrics indicative of pulse arrival time (PAT) are determined, where each metric can be determined by determining a time from one of the detected features of the CI signal to one of the detected features of the signal indicative of changes in arterial blood volume. Based on at least one of the metric(s) indicative of PAT, arterial blood pressure is estimated, which can include determining values indicative of systolic blood pressure, diastolic blood pressure, pulse pressure and / or mean arterial blood pressure, and / or changes in such values.

Diagnostic method and apparatus for a pressurized gas supply system
ActiveUS7568507B2Prevent excessive pressure risePreventing a potentially dangerous overheating problemLiquid fillingGas handling applicationsLine tubingEngineering
A diagnostic method for a gas supply system includes: determining a desired ramp rate for filling a vessel from a supply of compressed gas; monitoring the actual pressure of gas entering the vessel; and discontinuing the flow of gas into the vessel when the actual pressure deviates from the intended pressure at the desired ramp rate by an undesired amount. A system for carrying out the method includes a flow controller for controlling operation of the supply system to deliver compressed gas from a source to a vessel through a supply line at a desired ramp rate. The system employs a pressure monitor downstream of a control valve for measuring the pressure of gas directed into the vessel and transmitting pressure-related data to the flow controller, which closes the control valve to discontinue filling of the vessel if the actual pressure exceeds a permissible deviation from the intended pressure.

Surgical device with pressure monitoring ability
A device with a functional tip containing at least one active electrode capable of creating a controlled perforation in body tissue through the application of Radio Frequency (RF) energy is described. The position of the tip of the device can be determined in response to pressure sensed at the tip and determined by a monitor. The device is useful to remove or perforate unwanted tissue in a controlled manner in any location in the body, particularly in the atrial septum for controlled transseptal puncture. In this application, the device is introduced into the right atrium, and the functional tip is then positioned against the atrial septum. Energy is applied to create the perforation and pressure is monitored to determine if the perforation was created in a desired location. Other possible applications include the removal of plaque or thrombotic occlusions from diseased vessels.
