20100214088 | TIRE POSITION IDENTIFICATION SYSTEM AND METHOD - A tire position identification system and method include a transmitter that is configured to send an initiation signal. A receiver is configured to receive the initiation signal and attenuate the initiation signal until the initiation signal is within a first predetermined range of a reference signal. A controller identifies the position of a tire in response to the attenuation. In some embodiments, the reference signal is adjusted until the attenuated initiation signal is within a second predetermined range of the adjusted reference signal, and the position of the tire is identified further in response to the amount of adjustment of the reference signal. | 08-26-2010 |

20120136591 | PRESSURE MONITORING CIRCUITS AND METHODS - In order to provide better resolution over a wider pressure range the previously available, the techniques disclosed herein set an output precision of an analog-to-digital converter (ADC) based on a control signal provided by a control element. The control signal sets the output precision of the ADC to a first level to measure an ambient pressure within a first pressure range; and signal sets the output precision of the ADC to a second level to measure an ambient pressure within a second pressure range. | 05-31-2012 |
20120200408 | SYSTEMS AND METHODS FOR LOCALIZATION OF TIRE PRESSURE MONITORING SYSTEM WHEEL MODULES - Embodiments relate to unidirectional TPMS utilizing information from a corresponding vehicle system in order to correlate with vehicle speed information to be used in a tire localization methodology. In an embodiment, the vehicle system is an anti-lock brake system (ABS), and the vehicle speed can be used in a localization scheme that reconstructs a +/−1 g ripple with waveform, amplitude, frequency and phase parameters. Because the waveform is known to be sinusoidal (due to the wheel rotation), the amplitude is known to be 2 g peak-to-peak (due to the gravitational +/−1 g), the frequency depends on vehicle speed (which can be estimated from centrifugal force measurements), and an algorithm is discussed herein for determining the phase by correlation, the +/−1 g ripple can be reconstructed and the wheels localized therefrom. | 08-09-2012 |
20140129871 | FAIL SAFE CODE FUNCTIONALITY - Some aspects of the present disclosure provide for a system and method for fault mitigation of a non-volatile memory (NVM) store subject to error correction code (ECC) checking. A simple and robust means to test the integrity of failsafe code stored within the non-volatile memory prior to execution are disclosed. In some embodiments, the failsafe code comprises program elements to communicate the memory failure to other parts of the system, or to execute an orderly shutdown. In the event that an ECC error occurs, the failsafe code can be verified, and upon successful verification, executed. | 05-08-2014 |
