Abstract: While a transmission range selector is in a Park position, a controller engages multiple transmission shift elements to place the transmission in a tie-up state. In the tie-up state, both the transmission output shaft and the turbine shaft are held against rotation by the shift elements. To transition from Park to Drive, the controller releases one of the shift elements to place the transmission in a 1st gear state. To transition from Park to Reverse, the controller releases a different one of the shift elements to place the transmission in a reverse state. The controller may wait until the driver releases the brake pedal to release the shift element.

To energize the bus, the precharge contactor is closed and then the main contactor is closed. Upon completion of precharging, the main contactor is opened and energization of the bus is complete.

Abstract: A vehicle seating assembly includes a vehicle seat having a body. The body includes a center portion and four corner portions. A breathable coverstock covers a seating surface of the body. A plenum chamber is disposed below the body and is configured to receive and store a fluid. A cupped nozzle is disposed at each of the center portion and four corner portions. Each cupped nozzle includes a tapered base and a wide mouth proximate the coverstock. Fluid passageways extend through the body and connect the plenum chamber with the tapered base of each of the cupped nozzles. Pressurized fluid from the plenum chamber flows through the passageways to the cupped nozzles to deliver targeted airflow to a seated passenger.

Abstract: A park assist system may, in response to receiving a signal indicating that a remote inductive charge source is within a vicinity of a vehicle, transition from a park assist mode to a wireless charging mode. During the wireless charging mode, the park assist system generates instructions to assist a driver in positioning the vehicle relative to the inductive charge source.

The processor is also configured to scan a finger positioned on a vehicle fingerprint scanner for a fingerprint. The processor is further configured to verify that the fingerprint corresponds to an authorized driver and engage a vehicle ignition when the fingerprint corresponds to an authorized driver.

Abstract: A homodyne radar system includes a mixer that outputs a signal having a mixer output frequency that is a frequency difference between two input signals. When the frequency difference is small, low frequency noise may mask the actual signal. A variable phase shifter is added to one of the mixer inputs to change the phase at a predetermined rate of change. The phase shifter shifts the frequency of the input signal so that the mixer output frequency is offset by the predetermined rate. The low frequencies are mapped to frequencies that are above the noise frequencies. The phase shift may be achieved by adding a constant phase at predetermined time intervals. The sampling frequency for the resulting signal may need to be increased to accommodate the higher frequencies.

Abstract: The present invention appreciates that compounds comprising nitrogen-containing moieties that are at least divalent (e.g., urea, urethane, amide, etc.) can be reacted with azides using at least radiation energy to initiate the reaction between at least a portion of the compounds and the azides to form membranes that have surprisingly high selectivities for acid gases relative to nonpolar gases such as hydrocarbons. The membranes are also resistant to CO2 plasticization and have high acid gas flux characteristics. The resultant membranes can be extremely thin (e.g., 10 micrometers or less), which promotes high permeability for the acid gas and can translate into high productivity on a scaled-up, industrial level.
