A precision soft-touch gripping mechanism has a mounting plate attached to a robot arm. The plate supports a stepper motor. The output shaft of the stepper motor is connected through a spring to an elongated finger that slides in a central longitudinal slot of the plate and supports a first wafer gripping post, while on the end opposite to the first wafer gripping post the mounting plate pivotally supports two L-shaped fingers with a second and third wafer gripping posts on their respective ends. The mounting plate in combination with the first sliding finger and two pivotal fingers forms the end effector of the robot arm which is thin enough for insertion into a wafer-holding slot of a wafer cassette. The end effector is equipped with a mapping sensor for detecting the presence or absence of the preceding wafer, wafer position sensors for determining positions of the wafer with respect to the end effector, and force sensors for controlling the wafer gripping force. Several embodiments relate to different arrangements of gripping rollers and mechanisms for control of the gripping force and speed of gripping required for gripping the wafer with a soft and reliable touch.

A system and methods for the evaluation of the integrity of a wafer cassette and the disposition thereof are based upon evaluation of wafer measurement data obtained using a wafer sorter cassette mapping system utilized in-line during wafer sorting operations. In one embodiment, wafers are placed into slots in the wafer cassette. A wafer sorter cassette mapping sensor is scanned over the wafers in the wafer cassette. The positions of the wafers are measured while scanning the sensor over the wafers. The wafer position measurements are evaluated using a modeling system to determine slot positions, and a determination of the integrity of the cassette is generated. If the integrity determination indicates that the cassette is deformed beyond a predetermined value, the cassette is replaced. The measurement data may be stored in a data base for further trend analysis or for replacement forecasting.

A real-world vehicle includes: a plurality of data sources that generate sensor data that is spatially mapped to a real-world region; and a data fusion system configured to fuse or integrate (i) the spatially mapped sensor data with (ii) virtual data that has been generated outside the vehicle or has been generated independently of operation of the vehicle and is spatially mapped to a virtual world. This enables a fusion of the real world and the virtual world, enabling a self-driving automobile not only to interact with the physical world, but also to interact with virtual objects introduced into the path of the automobile (e.g., by a test or development engineer) to test how well the automobile and its autonomous driving system handle the virtual objects.

An exhaust gas recirculation control apparatus includes: an EGR valve adjusting a flow rate of EGR gas recirculated from an exhaust manifold to an intake manifold; a manifold absolute pressure (MAP) sensor measuring pressure inside the intake manifold; a throttle valve controlling the amount of inflow air; an igniter spraying fuel; an acceleration pedal angular position sensor; a crank position sensor measuring engine RPM; a vehicle speed sensor measuring a speed of a vehicle; and a control portion receiving a pressure signal from the MAP sensor, calculating a ratio of the EGR gas for a total volume of the intake manifold by using pressure variance inside the intake manifold, calculating pressure of the EGR gas by multiplying the pressure of the intake manifold and the ratio of the EGR gas, and converting the pressure of the EGR gas to a flow rate of the EGR gas.

An exhaust gas recirculation diagnosis device may include an EGR module that supplies an intake manifold with exhaust gas from an exhaust manifold, a MAP (manifold absolute pressure) sensor that measures pressure of the intake manifold, and a control portion that controls the EGR module such that the flow rate of the exhaust gas that is supplied from the exhaust manifold to the intake manifold is controlled by stages and monitors the value of the MAP sensor in a fuel cut off condition to diagnose whether the EGR module is faulty. The exhaust gas recirculation diagnosis device uses MAP sensor to perform exhaust gas recirculation and to diagnose the fault of the exhaust gas recirculation device.

An apparatus for diagnosing a failure of a sensor may include an engine; an intake manifold; a turbocharger including a turbine rotated by exhaust gas of the combustion chamber and a compressor provided at the intake line, rotated in connection with the turbine, and compressing external air; a map sensor measuring a pressure of a front end portion of the compressor; a differential pressure sensor measuring a differential pressure of front and rear end portions of an EGR valve provided at an EGR apparatus; an operation information detecting device measuring operation information including an engine speed and a load; and a controller determining whether an exhaust gas pressure is constant from the operation information and comparing a change amount of the differential pressure sensor signal and a change amount of the map sensor signal in the condition that the exhaust gas pressure is constant to diagnose a failure of the differential pressure sensor.

An airflow management system for an internal combustion engine comprises: an inlet portion to receive ambient air and a mass airflow (MAF) sensor adapted to sense mass flow rate of air passed throughthe inlet portion. The airflow management system comprises a throttle body to selectively restrict airflow and a throttle position sensor (TPS) adapted to sense an opening value of the throttle body.The airflow management system comprises an intake manifold in fluid connection with the throttle body and configured to direct airflow to each of a plurality of combustion cylinders. A manifold air pressure (MAP) sensor is adapted to sense air pressure at the intake manifold. A controller is programmed to monitor signals from each of the MAF sensor, TPS, and the MAP sensor, and generate a residualerror value based on a difference between a model-based value and a corresponding monitored signal. A response action is based on the trend of at least two residual error values.
