Abstract: A cooling system (500) for an electric drive system includes a cooling duct (502) extending between a first component and a second component. A motor (336) driven fan (510) creates an airflow within the duct. A first temperature sensor measures a first temperature of the first component and a second temperature sensor measures a second temperature of the second component. An electronic controller (540) receives the first temperature and calculates a first temperature difference between the first temperature and the first temperature limit (802) to generate a first command (836) for the motor (336). A second temperature difference between the second temperature and the second temperature limit (802) generates a second command (836) for the motor (336). The controller (540) then selects the greater of the first command (836) and the second command (836) to yield the maximum command (836), and controls the motor (336) based on the maximum command (836).
Abstract: A method and system for monitoring the health of a networked client computer node include health service agent software that scans the client computer node upon which the agent is installed. The health service agent software transmits data to a health service data manager identifying the type of client node upon which the agent is installed to permit retrieval by the manager of a health service task list specifying rules and executables applied by the health service agent to an associated client node.

Abstract: A sliding panel arrangement for a vehicle wherein a panel is adapted to be coupled to a vehicle body, at least two linear bearings or at least one longitudinal member being disposed on the panel, the other of the at least two linear bearings or at least one longitudinal member being adapted to be coupled to the vehicle body. The longitudinal member is sized and disposed to slide within the linear bearings, the panel sliding between closed and open positions over a vehicle compartment.
Abstract: A control system for controlling one or more actuators in a machine in response to installation of a tool to the machine detects the installation of a tool to the machine and prompts a user of the machine to configure the operation of the controller with respect to at least one of the one or more actuators.
Abstract: A method and system for viewing interface description documents, such as Web pages, performs a transition between a first graphic element and a second graphic element which are displayed according to the interface description document being viewed. To allow proper display of the graphic elements over a background, a transparency mask for each of the first and second graphic elements is generated and used in the image transition process. A display image, which is drawn on a video display for viewing, is initialized to contain the first graphic element. During the transition, selected pixels of the display image are replaced by corresponding pixels of the second graphic element over multiple frames until the display image has changed to contain the complete second graphic element.
