A collision avoidance control system for a vehicle is provided which is designed to determine a target collision avoidance deceleration required for a system vehicle equipped with this system to bring a relative speed between the system vehicle and a target object into agreement with substantially zero without a physical collision with the target object and to determine a possibility of collision with the target object as a function of the target collision avoidance deceleration. When the possibility of collision is higher than a given threshold level, the system starts to decelerate the system vehicle. This enables the avoidance of collision with the target object at a decreased operation load on the system.

Architecture for enhancing the encoding/decoding of information of a channel. A stream of incoming information bits are arranged into a first array of information bits. The first array of information bits are processed into a first code of bits, which bits form a plurality of first code words having a minimum distance to neighboring error events. Selected bits of the first code are rearranged into a second array of bits by intermittent successive rotations of the selected bits of the first code. A second code is then generated from the second array of bits to increase the minimum distance to the neighboring error events.

A distance-measuring device is used for measuring a distance between a vehicle and an obstacle. In so doing, dimensions of additional parts that are to be mounted on the vehicle and that project into a space between a detecting device for the distance measurement and the obstacle are taken into account.

The invention provides a blade type pneumatic motor with a variable expansion ratio. The blade type pneumatic motor comprises a front machine cover, a rear machine cover, a front end cover, a main exhaust hole rotation rear end cover, a rotor, a stator, a blade and a driving mechanism seal housing; a main exhaust hole, an inner ring groove, a top groove and a driven gear are machined on the main exhaust hole rotation rear end cover; the rotor and the stator are eccentrically arranged in an non-internally tangent manner; and a driving mechanism on the rear machine cover is packaged by the driving mechanism seal housing. According to practical requirements, under the driving of the driving mechanism, the volume at the moment of expansion is changed through the change of the position of the main exhaust hole, so that the variable adjustment of the expansion ratio is realized; and simultaneously, the external leakage of a working medium is alleviated through a leakage working medium backflow passage. The system is simple in structure and convenient to process.

An error correction encoding device is provided that combines redundancy data with source data, said device including: at least three encoding stages and at least two permutation stages.

Each encoding module implements a basic code and includes c inputs and c outputs, c being an integer. The permutation stages are inserted between two consecutive encoding stages and each permutation stage implements a c-cyclic permutation.

A method for interactive attentiveness enhancement of a vehicle driver includes steps of determining that a driver assistance function for semiautomatic control of the motor vehicle is active, detecting a stimulus which may be experienced by the vehicle driver upon an observation of the surroundings of the motor vehicle, detecting an input of the vehicle driver in response to the stimulus, determining a game result based on the input and the stimulus, and outputting a notice concerning the game result.

The invention discloses a keyboard. The keyboard is suitable for a handheld terminal and comprises 26 English letter keys, wherein each key is orthohexagonal, and all the keys are arranged alternately. By adoption of the technical scheme provided by the invention, an orthohexagonal design is adopted, so that the minimum distance between a key central point and a key edge is increased, and the probability that a finger presses other keys is reduced; and simultaneously, the keys are arranged alternately, even the finger presses other keys, only the edges of the keys are pressed, and an actual pressing effect cannot be easily achieved, so that on the basis of occupying the same area, the probability of input error is greatly reduced.
