<description><![CDATA[A system and method for demonstrating or testing operation of on-board diagnostics in a vehicle include imitating performance degradation of a vehicle hardware component and/or associated vehicle system by dynamically modifying at least one control system parameter value associated with the hardware component in response to a request to demonstrate operation of a selected diagnostic function or a specified performance degradation. Embodiments modify at least one control system parameter value associated with the input/output signal of a sensor/actuator to imitate a specified performance degradation. The diagnostics independently monitor operation of various vehicle control systems and operate to detect the degraded performance without knowledge of, or distinguishing between, whether the performance degradation was caused by an actual hardware component, or by the requested modification to the control system parameter value(s) associated with a particular hardware component.]]></description>

<description><![CDATA[First and second acceleration sensor elements for detecting the acceleration of a vehicle in the direction in which the vehicle travels, and the acceleration of the vehicle in the direction transverse to the travel direction of the vehicle are mounted on a sensor substrate which is mounted on a control substrate of a vehicle control device. With the sensor substrate positioned such that the sensing directions of the respective sensor elements are perpendicular to or parallel to the vertical line, the outputs of the respective sensor elements are detected as zero errors or gain errors. The sensor substrate is then mounted on a vehicle and with the vehicle placed on a horizontal surface, a signal is sent to an electronic control unit (ECU) of the vehicle control device so that the ECU can recognize that the vehicle is horizontal. Based on the outputs from the first and second sensor elements at this time, the deviation angles of the sensor elements about the X-axis and Y-axis directions are calculated. The acceleration in the X-axis direction is calculated from signals from wheel speed sensors. Based on the deviation angles and the acceleration in the X-axis direction, the deviation angle of the sensor elements about the Z-axis is calculated. Based on the thus calculated deviation angles and zero errors and/or gain errors, the outputs of the sensor elements are corrected to obtain true accelerations in the X-axis and Y-axis directions.]]></description>

<description><![CDATA[The present invention relates to an electronic controlled suspension apparatus capable of stopping vehicle height control when a vehicle turns and performing the vehicle height control when the vehicle goes straight ahead by using vehicle height sensors instead of a steering angle sensor, and a vehicle height control method of the electronic controlled suspension apparatus. To this end, there is provided an electronic controlled suspension apparatus, including a plurality of vehicle height sensors for measuring a height of a vehicle; a vehicle height adjusting actuator operable to adjust the height of the vehicle; air springs controlled by the vehicle height adjusting actuator; and an electronic controlled unit (ECU) for calculating a height difference value between the left and right sides of the vehicle based on vehicle height signals received from the vehicle height sensors and determining whether to operate or stop the vehicle height adjusting actuator through the comparison of the calculated height difference value between the left and right sides of the vehicle with a predetermined reference value.]]></description>

<description><![CDATA[Each of a portable device and an in-vehicle unit is provided with respective GPS receivers to determine a portable device position and a vehicle position. The portable device transmits a response signal including the portable device position in response to a request signal of the in-vehicle unit. The in-vehicle unit, only in a case where it is determined that the portable device position included in the response signal is within a predetermined area around the vehicle position, performs control of a lock/unlock state of a vehicle door in accordance with the identification result of the ID code included in the response signal. Accordingly, it is surely prevented that the door is remotely controlled by the portable device at far distances from the vehicle.]]></description>

<description><![CDATA[A method and an electronic search system for operating an automatic device, preferably an automatic lawnmower. The system comprises at least one first electrical cable ( 1,4,5,6 ) connected to at least one first signal generator ( 3,7,8 ) and at least one sensing system arranged on said device. Said sensing system detects at least one magnetic field being transmitted via said cable ( 1,4,5,6 ) and propagating through the air, the sensing system transmitting a processed signal to at least one driving element which contributes to the movements of said device in relation to a surface.]]></description>

<link>http://www.freepatentsonline.com/7613551.html</link>
<description><![CDATA[A vehicle remote operation device of optimized fail-safe function is disclosed that directs a vehicle to execute operations in response to a remote operation request made by a user of the vehicle. The vehicle remote operation device has a fail-safe control unit that changes a fail-safe criterion in execution of the remote operation according to a distance between the user and the vehicle. Preferably, the fail-safe criterion is moderated when the distance between the user and the vehicle is short. Alternatively, instead of measuring the distance between the user and the vehicle, a Smart Entry System is used to detect a key carried by the user to determine whether the user is near the vehicle.]]></description>

<link>http://www.freepatentsonline.com/7613258.html</link>
<description><![CDATA[A method for estimating signal quality of a spread spectrum signal is provided. The method includes squaring a plurality of in-phase correlation results and a plurality of quadrature correlation results, summing each squared in-phase correlation result and the corresponding correlation result to obtain a plurality of sum-of-square values, detecting a peak value among the plurality of sum-of-square results, calculating an average of non-peak values among the plurality of sum-of-square results. The peak value is regarded as a signal power value, while the averaged non-peak values are regarded as an average noise power value. A signal-to-noise ratio is then calculated based on the signal power value and the average noise power value. A method for determining the parameters for the tracking loop is also provided. The method includes estimating the signal-to-noise ratio of the spread spectrum signal, and determining the tracking loop parameters based on the signal-to-noise ratio.]]></description>

<description><![CDATA[An exhaust gas purifying apparatus for an internal combustion engine includes a particulate filter for trapping particulates found in the exhaust gases of the engine. The regeneration process for burning the particulates trapped in the particulate filter is executed by performing post injection of fuel. The regeneration process is suppressed according to an amount of fuel injected during post injection.]]></description>
