Abstract: An apparatus and method for measuring dynamic movement of a vehicle (10) by employing multiple GPS satellites and determining velocity based change in the carrier frequency of multiple satellite signals. The apparatus includes at least two GPS receiving antennas (12a and 12b) installed on a vehicle (10) at known locations and a controller (20) for processing received GPS signals (16a-16c) and monitoring a carrier frequency associated with the GPS signals. The controller (20) determines a change in the carrier frequency of the GPS signals due to Doppler effect. The controller (20) further determines a first inertial velocity vector of each of the receiving antennas (12a and 12b) based on the change in carrier frequency, and determines angular rate of the vehicle based on the inertial velocity vectors. The controller (20) further determines vehicle longitudinal and lateral velocity and acceleration as a function of the inertial velocity vectors.

Abstract: A system and method are provided for selectively setting one or more variable vehicle operating parameters or features by storing information representative of user/driver preferences on a portable information storage device, and later recalled to automatically adjust the same or other system or device to the same setting(s). Examples of such systems or devices includes seat position, mirrors, radio presets, climate control settings, Web sites, bookmarks, and mobile telephone presets. The personalized “settings” are thus available to be transported and transferred where desired by the possessor of the device.

Abstract: A hair conditioner-scalp stimulator solution made of liquid extracts from coconut, lemon and lime fruit.

Abstract: In a shifting mechanism housed in a case a first relatively rotating member rotates about an axis. A second relatively rotating member is selectively coupled and decoupled with the first member. A selector is moveable for actuating the coupling to mutually connect and disconnect the members. A resilient connection is provided between the coupling and selector. A method for shifting multi-speed axles without significant driver interaction by automatic synchronization is also provided.

Abstract: GPS sensors (14, 16; 30, 32, 34, 36) arranged in certain geometries in an automotive vehicle (10) to provide information that is processed by an on-board processor (18; 40) to derive parameters useful for warning, control, and/or documentation

Abstract: A vehicle traction control system is controlled in-part by a signal value indicative of estimated wheel torque. The estimated wheel torque value is produced within the vehicle's electronic engine control (EEC) module by summing a first value which indicated the estimated torque attributable to engine combustion and a second value which is proportional to engine acceleration/deceleration which indicates the amount of torque attributable to the inertial movement of engine and drive train masses. Before summing the two signal components, the signal which indicates combustion torque is delayed with respect to the signal indicating inertial torque by a delay interval whose duration varies with engine speed to take into account the delay between intake fuel rate changes and combustion forces as well as delays attributable to the timing of the calculations themselves.

Abstract: A vehicle traction controller includes engine control and brake control routines to improve vehicle traction. The engine control routine reduces average slip of driven wheels of the vehicle by retarding spark timing and by reducing air flow into the engine via an electronically controlled throttle. The engine control routine is entered if the average wheel speed of the driven wheels is above a predetermined threshold speed. Control of spark timing is performed by a Proportional-Differential (PD) control technique. The electronically controlled throttle is controlled by a Proportional-Integral-Differential (PID) control technique. The brake control routine operates to reduce the rotational speed of the driven wheel which has the highest rotational speed. The brake control routine is entered if one of the driven wheels has a rotational speed which is greater than a maximum desired speed and if the difference in speed between the driven wheels is greater than a maximum difference value.
