摘要： In order to prevent a catalyst for an internal combustion engine from decreasing efficiency by deterioration after long time use of the catalyst, the decreased efficiency of the catalyst is determined, and the internal engine is controlled based on results of the determination so as to maintain high efficiency of the catalyst. The catalyst is installed in an exhaust pipe of the engine. Sensors for detecting conditions of exhaust gas both at upstream side and downstream side of the catalyst are provided, respectively. As for the sensor, for example, an oxygen sensor of which output varies stepwise at &lgr;=1, or a sensor of which output varies in proportion to air-fuel ratio can be used. Detected values of the sensors are taken into a control unit, eliminating efficiency and deteriorating degree of the catalyst are estimated by comparison of the detected values, and the engine is controlled so that the eliminating efficiency becomes maximum. In accordance with the present invention, a preferable exhaust gas cleaning characteristics of the catalyst can be maintained because the decreased efficiency of the catalyst is determined exactly and the engine is controlled so as to prevent the catalyst from decreasing efficiency.
摘要翻译：为了防止内燃机的催化剂长时间使用催化剂后的劣化而降低效率，确定催化剂的效率降低，并且根据测定结果来控制内部发动机以保持高催化剂的效率。催化剂安装在发动机的排气管中。分别提供用于检测催化剂的上游侧和下游侧的废气条件的传感器。对于传感器，例如，可以使用其输出在λ= 1处逐步变化的氧传感器，或者其输出与空燃比成比例地变化的传感器。传感器的检测值被带入控制单元，通过比较检测值来估计催化剂的效率和劣化程度，并且控制发动机以使消除效率变得最大。根据本发明，由于精确地确定催化剂的效率降低并且控制发动机以防止催化剂效率降低，因此可以保持催化剂的优选废气清洁特性。

摘要： A sensor component that may be used in conjunction with a filter module may include a plurality of sensor packages. The latter, in turn, may incorporate one or more micro-electromechanical systems (MEMS) sensors to measure various characteristics of fluid flow and filtration. A single sensor component may be adapted to measure the pressure, temperature, flow rate, differential pressure, conductivity, viscosity, pH level, etc. of the fluid at an upstream and a downstream location. Sensor measurements may be obtained continuously in order to monitor and indicate fluid conditions, including the use of a warning mechanism to indicate an out-of-range condition when the measurements fall outside of pre-set limits. Depending on the application and the fluid being filtered, data, including measurement data, may be transmitted through electrical connections or wirelessly. In wireless configurations, a sleep-mode may be included to maximize the life of local power supplies.

摘要： The test system provides conventional analog outputs that allowing application of power system conditions simulation to a device under test. The test device has a communication interface which sends and receives digital communication to and from protection relays, control devices, and meters, known as intelligent electronic devices (IEDs). The test device interacts with the devices under test over a direct communication link or a substation local area network. The communication protocol includes digital communication to send and receive messages which simulate virtual switching and control equipment status and other intelligent electronic device (IED) data and status. The test system monitors the operation of the IED device under test based on the IED digital communication data received and the contained control signal status utilizing the digital communication interface as a substitute for the conventional hard-wiring of IED binary inputs and outputs.

摘要： An exhaust gas recirculation (EGR) valve coil temperature is estimated non-intrusively using only existing sensors. In one embodiment an EGR valve coil temperature estimator running on a powertrain control module estimates the EGR valve coil temperature as a linear function of estimated charge temperature, inlet air temperature, coolant temperature, and vehicle speed. Coefficients of the mathematical function, which describe the degree of association between the inputs and EGR valve coil temperature, are calculated by measuring the actual EGR valve coil temperature over wide operating conditions. The powertrain control module uses the EGR valve temperature estimated in this manner to vary the drive signal to the EGR valve coil to open the EGR valve a desired amount.

摘要： A semiconductor manufacturing automation method for analyzing a patterned feature formed on a semiconductor layer is disclosed. At least one patterned feature is scanned to generate an amplitude modulated waveform signal of the line and neighboring space characteristics. Signal processing is automatically performed on this waveform by an in-line computational source to extract known patterned features based on the profile of the amplitude modulated waveform signal. The extracted waveform segments are subjected to known geometric shapes to determine if the waveform indicates a normal or abnormal patterned feature on a semiconductor layer.

摘要： Embodiments of the present invention are directed to preventing calibration of a device to exceed the full design travel, for instance, during aggressive operation or play. A limiter is coupled to the rotational sensor to limit the full travel output signal to a fixed and repeatable maximum value no matter how aggressive the operation or play becomes. The limit is desirably set at such a point as normal operation or play will always reach. In this way, the automatic calibration of the device will not exceed the full design travel. In one embodiment, an input device comprises a user manipulable object configured to rotate around a rotational axis relative to a base. A rotational sensor includes a sensor body coupled with a sensor shaft which is rotatable relative to the sensor body around the rotational axis. The sensor shaft is connected with the user manipulable object to rotate with the user manipulable object around the rotational axis. An actuator is coupled with the user manipulable object to rotate with the user manipulable object. The actuator is configured to be coupled with the sensor body, after the user manipulable object has rotated to reach a preset limit, to rotate the sensor body with the sensor shaft and the user manipulable object beyond the preset limit.

摘要： A system and method for testing an airbag proximity suppression system that includes a positioning system that controls movement of an occupant model and toward a suppression zone. A proximity sensor provides a first output signal indicative of when the occupant model actually enters the suppression zone by monitoring movement of a position marker. The airbag suppression system, the device under test, provides a second output signal indicative of when the airbag suppression system detects that the occupant model has entered the suppression zone. The timing difference between the first and second output signals is indicative of a performance factor of the airing suppression system.
