An automobile seat includes a seat cushion and a seat back tiltably mounted on the seat cushion. The automobile seat also includes a seat cushion frame, a side frame mounted on the seat cushion frame, a seat back frame mounted on the side frame so as to be rotatable within a limited angle, and a fastening member mounted on the seat back frame. The side frame has an insertion hole defined therein in which the fastening member is inserted and also has an impact absorbing structure. Where a load greater than a predetermined value is inputted to the seat from behind, a lower portion of the seat back frame is pushed upon a rearward movement of a seat occupant to thereby cause the fastening member to move rearwards while deforming the impact absorbing structure. As a result, the seat back frame rotates with respect to the side frame, and an impact is absorbed by the deformation of the impact absorbing structure.

The mirror mechanism is operative to either turn freely about the ball on a horizontal plane or turn about the ball on a vertical plane in a limited angle.

The invention relates to a stabilizer for a motor vehicle. Known one-piece stabilizers are designed either solely for operation in road traffic or solely for off-road operation. Two-piece stabilizers that comprise an engaging and disengaging clutch have disadvantages regarding quality and safety. The invention provides a clutch, drivers (14, 17) of which form at least two adjustable gaps in the peripheral direction. The gaps can be filled by at least two locking elements (25) that can be displaced to a certain extent. The locking elements (25) and said drivers (14, 17) are constantly in positive engagement with one another in the peripheral direction and are adjusted to one another in such a manner that the locking elements (25) and the drivers (14, 17) are interlocked without play in the locked final position and that they can be rotated towards one another across a limited angle in the unlocked final position.

A display screen support device includes a base unit providing an upright shaft and a stop member at the upright shaft, a first support arm including a first pivot-connection device coupled to the upright shaft and supported on the stop member and a first extension device transversely extended from the first pivot-connection device for supporting a display screen, and a second support arm including a second pivot-connection device coupled to the first pivot-connection device and a second extension device transversely extended from the second pivot-connection for supporting another display screen. The second pivot-connection device of the second support arm relative can be biased relative to the first pivot-connection device of the first support arm within a limited angle for allowing adjustment of the relative angular position between the two supported display screens.

Disclosed is an emergency feathering control method for a wind generating set. After emergency stopping of the wind generating set, variable rate stopping strategies are adopted. When emergency stopping is just started, feathering is conducted fast so as to reduce the forward load, and after the blade pitch angle reaches the limited angle or time reaches the limited time, the feathering speed needs to be decreased so as to reduce the negative direction load. The emergency feathering control method comprises the following steps that (1) the variable rate stopping demarcation point of the wind generating set is determined; (2) the system state of the wind generating set is monitored; (3) a variable blade execution system mode of the wind generating set is determined; and (4) the wind generating set conducts variable blade operation according to the variable rate stopping mode adopted by a variable blade execution mechanism.

An automobile seat includes a seat cushion frame, a side frame mounted on the seat cushion frame, and a seat back frame mounted on the side frame so as to be rotatable within a limited angle. An elastic member is mounted on one of the side frame and the seat back frame, while a guide portion having a holding portion for holding the elastic member is formed on the other of the side frame and the seat back frame, the guide portion. The seat back frame is fixed to the side frame in a normal sitting condition in which the elastic member is held in the holding portion. In the case where a load greater than a predetermined value is inputted from behind, a lower portion of the seat back frame is pushed by a lumbar part of a seat occupant upon a rearward movement of the seat occupant to thereby deform the elastic member, which in turn leaves the holding portion and moves rearwards along the guide portion, thus causing the seat back frame to rotate with respect to the side frame and causing the headrest to move forwards.

The invention discloses a channel information feedback method and a system. The channel information feedback method comprises the following steps: a pre-coding matrix required to be fed back can be decomposed into the product of a plurality of Givens rotating matrixes, wherein each rotating matrix is only related to a rotating angle; and the corresponding rotating angle of the rotating matrix after being decomposed is fed back. The method and the system provided by the invention are a channel compression quantized feedback solution based on the Givens transformation, wherein the pre-coding matrix required to be fed back can be transformed into a limited angle value through continuous Givens rotation, and a base station can rebuild a channel matrix by using the fed-back quantitative angles so as to calculate a pre-coding vector, so that the feedback cost can be effectively reduced. Compared with the traditional scalar quantization, the channel information feedback method can effectively reduce the number of the quantitative elements, thereby decreasing the feedback quantity. With respect to the vector quantization, the only requirement is to carry out the operation of decomposition and quantization, so that the system complexity can be effectively lowered under the condition of ensuring the system performance.
