  • Method and system for diagnostics of a particulate matter sensor
    Patent number: 8230716
    Abstract: A diagnostic method and system is described for diagnosing an operating condition of a conductive particulate matter sensor. The sensor has a substrate and two electrodes on the substrate adapted to collect particulate matter between the electrodes, thereby establishing an electrically conductive path through collected particulate matter between the electrodes that can be detected by measuring electrical resistance between the electrodes, Relect. The diagnosis is performed by detecting whether water vapor condensate may be present between the electrodes and if it is, then measuring resistance between the electrodes while subjecting the sensor to conditions sufficient to evaporate any water vapor condensate and diagnosing a validation that the sensor is in proper operating condition if resistance increases in a manner consistent with evaporation of condensate.

  • Method to determine a quality acceptance criterion using force signatures
    Patent number: 8224623
    Abstract: A method is provided to determine a quality acceptance criterion using force signatures measured on a first and a second set of elements. The first set has no quality defect and the second set has a deliberate quality defect. Selection of an initial subset of time points is based on statistical analysis of the force data on the force signatures in the two sets. The quality acceptance criterion includes a quality threshold established using Mahalanobis Distance (MD) values and the MD values are produced from force data at a selected initial subset of time points for each element in the two sets. An output of the determined quality acceptance criterion is using the defined quality threshold to separate an element having a force signature into a group of elements having no quality defect or into a group of elements having a quality defect like the deliberate quality defect.

  • Compact switchable hydraulic lash adjuster with hydraulic lost motion assist
    Patent number: 8215276
    Abstract: An improved deactivation hydraulic lash adjuster wherein the prior art lost motion spring or springs formerly located within the body of the DHLA and below the pin housing are either omitted completely or are reduced in length, spring force, and/or number and are augmented hydraulically, allowing a shorter, more compact lifter body and reduced overall lifter length. The prior art lost motion spring chamber becomes a hydraulic chamber connected to a new pressurized oil supply gallery containing an accumulator in the engine. An embodiment having no lost motion spring and solely hydraulic lost motion return can be even shorter than a spring-hydraulic hybrid because the potential hydraulic pressure to be brought against the pin housing is not a function of the length of the lost motion chamber, which length is limited only by the required displacement of the pin housing.

The cathode sides of the OLEDs are interconnected by a light transmitting layer overlaying the cathode side that is electrical conductive. On the side of the substrate opposite the OLEDs is an array of anode contacts configured to form an electrical contact with a driver circuit.

  • SYSTEM AND METHOD FOR ASSISTING A VEHICLE OPERATOR TO PARALLEL PARK A VEHICLE
    Publication number: 20120173080
    Abstract: A method and a system for assisting a vehicle operator to parallel park a vehicle. The method and system use only a single proximity sensor to detect a suitable parallel parking space and monitor the position of the vehicle when backing into the parallel parking space. Assistance to parallel park the vehicle may be as little as providing indications or warning to a vehicle operator while the vehicle operator backs the vehicle into the parallel parking space, or may be as much as taking complete control of the vehicle away from the vehicle operator, and autonomously parallel parking the vehicle.
