| 20100000879 | ELECTROCHEMICAL NOISE AS A LOCALIZED CORROSION INDICATOR - Systems and methods are presented for a method for measuring or monitoring localized corrosion in which an electrochemical noise (ECN) signal is sensed and filtered by a high-pass or band-pass filter to remove low frequency components not related to localized corrosion and a standard deviation of the filtered signal is computed and scaled to provide a localized corrosion value. | 01-07-2010 |
| 20090268553 | ULTRASONIC SENSOR SYSTEM AND METHOD FOR SENSING DISTANCE - Methods and ultrasonic sensor systems are presented for sensing distance in which an acoustic output signal is directed toward a target and acoustic input signals are received from the direction of the target, and the received signal is compared with a selected one of a plurality of different receiver threshold curves to identify the acoustic wave travel time to the target and back while differentiating between the target and acoustic waves reflected more than once and waves reflecting off obstructions between the sensor and the target, where the user selectable receiver threshold curves are tailored for different target and/or obstruction conditions. | 10-29-2009 |
| 20090189600 | METAL FACE INDUCTIVE PROXIMITY SENSOR - Metal face inductive proximity sensors and methods are presented for sensing the presence or absence of a target object in a target sensing area in which a coil system is operated to generate a magnetic field extending outward from the sensing face at a frequency in a range that maximizes a relative target effect for the sensing face area, material, and thickness, and a target material from which the target object is made to allow the protective advantages of metal sensing face materials while enhancing sensing distance by optimizing the ratio of the target energy loss to the energy loss in the metal face. | 07-30-2009 |
