    Abstract: A method is presented for diagnosing a particulate matter sensing system, where the system includes a sensing element having two electrodes spaced from one another. The method determining at a first time during a cool-down event a first sensing element temperature and a resistance of the sensing element, and determining at a later second time during the cool-down event a second sensing element temperature and the resistance of the sensing element. The method further includes calculating a predicted sensing element resistance at the second sensing element temperature, based on the first sensing element temperature, the resistance of the sensing element determined at the first time, and a predetermined model of the resistance vs. temperature characteristics of the sensing element. A fault condition for the system may be indicated based on a comparison of the predicted sensing element resistance at the second sensing element temperature and a measured sensing element resistance.

    Abstract: A camshaft phaser includes an input member and an output member defining an advance chamber and a retard chamber; a valve spool moveable along an axis between an advance position and a retard position and having a valve spool bore with a phasing volume and a venting volume defined therein such that the phasing volume is fluidly segregated from the venting volume, the valve spool having a first spool recirculation passage and a second spool recirculation passage which is diametrically opposed to the first spool recirculation passage. The first spool recirculation passage and the second spool recirculation passage provide paths for oil to flow from the advance chamber or the retard chamber to the phasing volume depending on the position of the valve spool.

    Abstract: A USB hub module which is configured to enable a vehicle's embedded USB host to connect to multiple mobile devices through a USB hub, regardless of whether the mobile devices are configured to act as USB hosts or USB devices, without providing USB OTG controllers or additional vehicle wiring or inhibiting functionality of consumer devices connected the module while one consumer device connected to the module operates in USB host mode. Preferably, the module is configured so that no additional cabling or hardware changes are required to the head unit. The module can be employed between the embedded USB host, USB hub and at least one consumer accessible USB port. When the consumer device is acting as a USB host, signals between the consumer device and the vehicle's embedded USB host are processed through a bridge, thereby rendering the consumer device compatible with the embedded USB host.

    Abstract: A method for calibrating a mounting-device used for automatically mounting a contact-part attached to an electrical line with a connector-housing includes the steps of providing the mounting-device, marking a plurality of marking-points, capturing an image of the plurality of marking-points, and determining the positions of the plurality of marking-points. The mounting-device comprises a holder for the connector-housing, a positioning-device that includes a moveable-gripper that includes a marking-device, a camera configured to capture an image of a portion of the holder, and a control unit in communication with the positioning-device, the camera, and the moveable-gripper. The control unit determines the positions of the marking-points based on the image. The positions are indicative of an actual insertion-position of the contact-part into the connector-housing by the moveable-gripper. The control unit stores the positions of the marking-points in a memory of the control unit.
