Abstract: Methods and systems are provided for controlling coolant flow through parallel branches of a coolant circuit including an AC condenser and a charge air cooler. Flow is apportioned through each of an air-conditioning condenser, a charge air cooler (CAC), and a transmission oil cooler (TOC) of the coolant circuit to maintain an estimated transmission oil temperature (TOT) below a threshold. The TOT is estimated from a torque converter slip ratio.

Abstract: Methods and systems are provided for controlling coolant flow through parallel branches of a coolant circuit including an AC condenser and a charge air cooler. Flow is apportioned responsive to an AC head pressure and a CAC temperature to reduce parasitic losses and improve fuel economy. The flow is apportioned via adjustments to a coolant pump output and a proportioning valve.

Abstract: Techniques for transferring printable content from a remote device to an eBook reader include exposing a network printer interface that represents the eBook reader as a physical network printer. The remote device can be configured with a printer driver corresponding to the network printer interface, and a user may print documents from the remote device in order to transfer them to the eBook reader.

Abstract: Methods are provided for engine coolant system diagnostics. In one example, engine coolant system malfunction is indicated based on an engine coolant temperature inference model, whereas in another example engine coolant system malfunction is indicated based on a time-based monitor, where the inference model is enabled at ambient temperatures above a predetermined threshold, and where the time-based monitor is enabled at ambient temperatures below the predetermined threshold. In this way, accurate engine coolant system diagnosis may be accomplished under ambient temperature conditions wherein the engine coolant temperature inference model may be compromised.

Abstract: One example method includes varying oil injection by an oil injector onto a piston of an engine to accommodate different operating conditions. For example, by adjusting oil injection, suitable cooling effects can be provided without providing additional oil that increases the amount of oil deposits in the engine. In this way, the risk of pre-ignition can be reduced.

Abstract: A system and method for producing solid pellets from a slurry HDC pitch is disclosed which utilizes a polymer additive that is mixed with the pitch to increase the softening point of the solid pellets.

Abstract: Methods and systems are provided for diagnosing an intake air temperature sensor in a hybrid electric vehicle. An engine temperature is compared to each of an intake air temperature sensed before an engine start but after sufficient engine soak, as well as an intake air temperature sensed after selected vehicle operating conditions have elapsed since the engine start. Based on discrepancies between the air temperature and the engine temperature, degradation of the sensor is determined.

Abstract: Methods and systems are provided for diagnosing each of a plurality of engine cooling system components including various valves and grill shutters. Each valve may be individually closed and opened for a specified duration, and corresponding changes in coolant temperature may be monitored. If all the components are functional, the various valves may be adjusted to stagnate coolant at the engine and expedite engine warm-up during a cold-start.

Abstract: Embodiments for indicating degradation of a piston-cooling jet system are provided. In one example, an engine method comprises indicating degradation of a piston-cooling jet system in response to a relationship between engine speed and oil pressure at maximum oil pump displacement conditions. In this way, engine operation may be adjusted in response to an indicated degradation.

Abstract: A system and method for demonstrating or testing operation of on-board diagnostics in a vehicle include imitating performance degradation of a vehicle hardware component and/or associated vehicle system by dynamically modifying at least one control system parameter value associated with the hardware component in response to a request to demonstrate operation of a selected diagnostic function or a specified performance degradation. Embodiments modify at least one control system parameter value associated with the input/output signal of a sensor/actuator to imitate a specified performance degradation. The diagnostics independently monitor operation of various vehicle control systems and operate to detect the degraded performance without knowledge of, or distinguishing between, whether the performance degradation was caused by an actual hardware component, or by the requested modification to the control system parameter value(s) associated with a particular hardware component.

Abstract: The invention is a matrix for preparing a tissue sample made of saline, albumin, gelatin, formaldehyde, a detergent, sucrose, lysine, and glutaraldehyde. The matrix is formed by first preparing a solution of saline, albumin, and gelatin, and then mixing the solution with formaldehyde, a detergent, and sucrose. Immediately prior to fixation of the tissue, a separately prepared lysine-glutaraldehyde mixture is added. The resulting matrix will harden rapidly and may be used to fix tissue samples for histological processing. In particular, a layer of the matrix may be poured into a mold and allowed to harden to form a base. One or more tissue samples may then be pinned to the base of matrix in the mold and then covered with the matrix. Once the matrix hardens, the pins and mold may be removed, and the tissue sample or samples embedded in the matrix are ready for sectioning.
