  • Patent number: 9802293
    Abstract: The present invention provides methods for making a pre-conditioned chemical mechanical (CMP) polishing pad having a pad surface microtexture effective for polishing comprising grinding the surface of the CMP polishing pad having a radius with a rotary grinder while it is held in place on a flat bed platen surface, the rotary grinder having a grinding surface disposed parallel to or substantially parallel to the surface of the flat bed platen and made of a porous abrasive material, wherein the resulting CMP polishing pad has a surface roughness of from 0.01 ?m to 25 ?m, Sq. The present invention also provides a CMP polishing pad having a series of visibly intersecting arcs on the polishing layer surface, the intersecting arcs having a radius of curvature equal to or greater than half of the radius of curvature of the pad and extending all the way around the surface of the pad in radial symmetry around the center point of the pad.

  • Patent number: 9567920
    Abstract: Rev-matching techniques that do not require a gear position sensor or a clutch position sensor are provided for a manual transmission of a vehicle. The techniques include predicting an intent of a driver to shift gears of the manual transmission based on whether the vehicle is accelerating or decelerating; predicting a shift of the manual transmission from a current gear to a different target gear based on the predicted driver intent; and detecting a trigger condition indicative of the predicted shift of the manual transmission based on a position of a clutch pedal configured to control engagement/disengagement of a clutch of the manual transmission. In response to detecting the trigger condition, a torque request for the torque generating system is modified to obtain a modified torque request, and the torque generating system is controlled based on the modified torque request.

  • Publication number: 20160305358
    Abstract: A first computer-implemented diagnostic method can run in response to an imminent deceleration fuel cutoff (DFCO) event. A second computer-implemented diagnostic method can run on engine shutdown. Both diagnostic methods involve controlling fuel injectors and a fuel pump to make the fuel rail pressure change from a desired minimum to a desired maximum. Measurements from the fuel rail pressure sensor at these endpoints can then be used to detect a fault of the fuel rail pressure sensor. One or both diagnostic methods can be implemented.

  • Publication number: 20160138527
    Abstract: Rationality diagnostic techniques for an intake oxygen sensor are utilized to detect sensor malfunction. A non-intrusive diagnostic technique includes passively detecting when an exhaust gas recirculation (EGR) valve position crosses low/high position thresholds, whereas an intrusive diagnostic technique includes actively commanding the EGR valve to predetermined low/high positions. During a period after the EGR valve position reaches/crosses at least one of the low/high positions/position thresholds, respectively, maximum and minimum intake oxygen concentration is monitored. When the EGR valve position has crossed both the low/high positions/position thresholds and a difference between the maximum and minimum oxygen concentrations is less than a respective difference threshold, a malfunction of the intake oxygen sensor is detected. A malfunction indicator lamp (MIL) could be set to indicate the malfunction.

  • Patent number: 9224252
    Abstract: A method of diagnosing rationality of a humidity sensor output signal determines that the humidity sensor output signal has passed a rationality diagnostic if the output signal is changing sufficiently. If the output signal is not changing sufficiently, the method determines whether it should be changing sufficiently by whether a humidity capacity index determined based on temperature and pressure local to the humidity sensor is changing sufficiently. If the humidity capacity index is changing sufficiently and the humidity sensor output signal is not, the method determines that the humidity sensor output signal has failed a diagnostic check. Upon determining that the humidity sensor output signal has failed the diagnostic check a predetermined number of times, the method determines that the humidity sensor output signal has failed the rationality diagnostic.

  • Publication number: 20060072520
    Abstract: Improved throughput is provided in a spacecraft TDMA cellular communications system by introducing a standby state, in addition to the idle and transfer states, of the medium access control (MAC) protocol, which controls the transfer of data over the radio interface between the network and the user terminals. The terrestrial locations include mobile user terminals and gateways which provide connections to the land line telephone system and/or the land packet data network i.e. Internet service provider. Each of the terrestrial terminals and gateways include a MAC to control the transmitting and receiving of data between the gateway and user terminals. Since packet data is bursty, multiple transitions occur between the idle and transfer states during data transfers. The new standby state maintains synchronization, reducing the transition time to the data transfer state by comparison with the transition time from an idle state where the network does not maintain user synchronization.

  • Publication number: 20050209034
    Abstract: Tension within a power transfer system is measured by tension evaluator that includes an actuator, a first sensor, and a second sensor. The actuator applies a first load and a second load to a chain. The chain is moved a first amount of deflection in response to the first load and the chain is moved a second amount of deflection in response to the second load. The first sensor senses an event. A third amount of deflection is associated with the event. The second sensor senses an amount of travel of the chain between the second amount of deflection and the third amount of deflection.
