The invention discloses a seat angle adjusting device comprising a ratchet wheel, a stop plate, a locking slider and a pawl. A driving device can optionally drive the locking slider to a locking position or a retracting position and drive the pawl to a stretching position or a retracting position. The stop plate is provided with a first stop limit portion and a second stop limit portion. When the first stop limit portion is stressed by rotation torque in rotation direction, the locking slider at the locking position is abutted against the circumference of the first stop limit portion. When the rotation torque is larger than a first preset torque value, the first stop limit portion can deform circumferentially under the action of the locking slider, and the pawl at the extending position can be driven to rotate by the ratchet wheel to a toothed portion on one side of the pawl to mesh with the ratchet wheel completely. When the rotation torque is larger than a second preset torque value, the second stop limit portion can be abutted against the pawl, and the second preset torque value is larger than the first preset torque value. The invention further provides a seat utilizing the seat angle adjusting device on the basis of the above structure.

InactiveUS20080234912A1Reduce roll momentPeak lateral friction be reduceDigital data processing detailsAutomatic initiationsBrake torqueRoll moment
A method is provided for counteracting a roll moment in a vehicle rollover event. A potential occurrence of the rollover event is detected over an outside wheel. The potential rollover occurrence event is detected when a tire lateral force is greater than a lateral acceleration force. A braking torque is applied to at least one outside wheel (rear outside, front outside or both outside wheels) for producing a longitudinal wheel slip on the at least one outside wheel wherein the longitudinal wheel slip increases a longitudinal force acting on the at least one outside wheel, cooperatively producing a vehicle yaw for off setting an oversteering condition. The peak lateral friction is reduced between a tire coupled to the at least one outside wheel and an underlying road surface in order to reduce the peak lateral friction and the roll moment.

Low friction linear tracking tone arm

This invention is provides a means of playing LP records with minimal distortion. Low distortion is achieved by eliminating tracking error normally associated with pickup cartridges mounted to pivoting tone arms. This invention discloses a tone arm that constrains the motion of the stylus to straight radial path, mimicking the cutting path of the record lathe, supported on parallel rails by free rolling spherical bearings. Unlike many previous linear tracking tone arms, this invention does not rely on air pressure or servo motor mechanisms. The use of free rolling bearings or axles between parallel tracks fashioned from rails, rods or tubes, eliminates all sources of lateral friction other than pure static and rolling friction of the balls on the rails, rods or tubes. In the preferred embodiment, the fixed rods or tubes are driven synchronously, thereby eliminating static friction of the supporting rolling balls. Friction is further reduced using magnetic or buoyant support of the tone arm to reduce bearing load to that amount minimally sufficient to maintain full contact between the rolling balls and the upper and lower rods.
