Abstract: A method and device for roll stabilization of a motor vehicle are provided. On the basis of a measured transverse acceleration or a calculated transverse acceleration of the motor vehicle, actuating signals are generated for actuators which are associated with a front axle and a rear axle of the motor vehicle and which provide support torques on the front axle and/or on the rear axle for roll stabilization. To ensure a satisfactory self-steering effect of the motor vehicle, a torque distribution between the support torque provided on the front axle and the support torque provided on the rear axle is modified on the basis of a first signal which allows conclusions to be drawn concerning the actuation of a gas pedal, and/or on the basis of a second signal which allows conclusions to be drawn concerning the actuation of a brake pedal.

Abstract: A process of monitoring a drive direction of an automatic or automated vehicle transmission at near-zero vehicle speed via an engaged gear. A desired direction of drive of the transmission is determined from an engaged gear at the time the vehicle begins motion. An actual direction of drive is determined from the transmission and, if different from the desired direction of drive, an error signal is produced. The process includes determining the actual drive either from a sensed rotational direction of a transmission input shaft and a sensed rotational direction of a transmission output shaft or a sensed valve setting, a sensed pressure in an transmission electro-hydraulic control system or on a transmission shifting element or from a sensed direction of rotation of a transmission gearset element or from axial movement or force of a transmission constructional element.

Abstract: An optical sensing device includes a shell, at least one light emitting member, a rotating type shading assembly and at least one optical sensing member. The shell is formed with a black-body condition space having a light emitting chamber, a shading chamber and at least one optical sensing chamber. The light emitting member projects a light beam. The rotating type shading assembly includes a pivot and a shading member. The shading member is pivotally connected to the pivot in the shading chamber, and has a weight center offset from the pivot center. When the optical sensing device is tilted, the shading member is rotated to make the weight center located in a lowering azimuth with respect to the pivot. The optical sensing member is arranged in the optical sensing chamber, and senses the light beam to accordingly send out a sensing signal.

Abstract: A GNSS enabled mobile device selects an associated local GNSS clock or host clock as a clock source to operate a GNSS radio and one or more non-GNSS radios within the GNSS enabled mobile device. When the GNSS radio is in a GNSS active mode, the local GNSS clock is turned ON and selected to be shared with the host. The host operates the GNSS radio and the non-GNSS radios only using the local GNSS clock instead of the host clock. The host clock is turned OFF to save power. When the GNSS radio is in a GNSS inactive mode, the host clock is turned ON and selected to operate the non-GNSS radios. The local GNSS clock is turned OFF to save power. The non-GNSS radios comprise a Bluetooth radio, a WiFi radio, a FM radio, a cellular radio and/or a WiMAX radio.

Abstract: An antenna assembly for receiving the GPS signals in a global positioning system (GPS) receiver module automatically orients the antenna to better receive the GPS signals. The antenna is oriented by a positioner (e.g., a counterweight) that automatically rotates a frame on which the antenna is mounted. The GPS receiver module may also include multiple antennas oriented in different directions to maintain good reception of the GPS signals in any position. The multiple antennas are oriented in a manner so that the poor reception range an antenna is covered by other antennas. Signals from multiple antennas may be combined or chosen for processing by a GPS processor. Also, multiple GPS receiver modules may be deployed in close proximity so that wireless communication between the GPS receiver modules may be established.

Abstract: Noise discrimination in signals from a plurality of sensors is conducted by enhancing the phase difference in the signals such that off-axis pick-up is suppressed while on-axis pick-up is enhanced. Alternatively, attenuation/expansion are applied to the signals in a phase difference dependent manner, consistent with suppression of off-axis pick-up and on-axis enhancement. Nulls between sensitivity lobes are widened, effectively narrowing the sensitivity lobes and improving directionality and noise discrimination.
