A monolithic ferrule / endcap / optical fiber structure is provided wherein an optical fiber is terminated in a ferrule and bonded by fusion to form a monolithic unit which minimizes optical loss and is typically capable of transmitting high power laser radiation, preferably on the order of 500 W and higher, without damage to the optical fiber and ferrule. Ferrule, endcap, optical fiber and fusible powder are composed of material of substantially the same physical characteristics such that, when all are fused together, the structure so formed is monolithic and the optical path is transparent.

A system for measuring flow rate with at least a first and a second flow meter provides a flow-rate measurement system which easily allows self-monitoring. This result is achieved by the system in that the first flow meter and the second flow meter differ from one another and / or have different orientations for the flow rate measurement, and each have an evaluation unit which produces data from the flow rate measurement. Furthermore, there is a monitoring device which is connected to the evaluation units such that the monitoring device acquires data produced by the evaluation units, and which is made such that it produces at least one comparison result from a comparison of the data produced by the evaluation units and signals at least the occurrence of a fault state which is associated with at least one comparison result.

The invention relates to a compact, flexible CSP installation (1,101,201,301,401) for endless, semi-endless and batch operation with a casting machine, a roughing stand group (7,111,211) and a finishing stand group (12,118,218), wherein for the batch operation or the semi-endless operation, a coil store (8,113,213,501) is integrated into the roll table, which stores the pre-strip or slab coming from the roughing stand, with the coil store being deactivated in the case of endless operation. The coil store (8,113,213,501) is designed for an increased holding quantity of pre-strips or slabs such that two, three or more pre-strips or slabs can be wound to jumbo coils on a coil.

A pouch-type rechargeable battery and its method of manufacture includes: an electrode assembly having a resin layer attached to the outer surface of an electrode tap, and a pouch having a sealing part formed on the ends of the top and bottom thereof, housing the electrode assembly. The resin layer is positioned inside the sealing part and sealed by heat and pressure for preventing it from being exposed outside the sealing part. Thus, the pouch-type rechargeable battery is adapted to seal the resin layer in the sealing part, instead of exposing it outside the sealing part so as to reduce the longitudinal length of the battery, thereby improving the capacity of the battery.

The invention discloses a chassis with a four-wheel steering function. The chassis comprises a rear steering axle. The rear steering axle comprises a rear wheel steering drive axle and a rear wheel steering reversal mechanism. The rear wheel steering drive axle comprises an axle body, a left steering knuckle, a right steering knuckle, two steering knuckle arms, two trapezoid arms and a rear steering tie rod. The left steering knuckle and the right steering knuckle are arranged at the two ends of the axle body respectively. The two steering knuckle arms are fixed to the left steering knuckle and the right steering knuckle respectively. The two trapezoid arms are fixed to the left steering knuckle and the right steering knuckle respectively. The rear steering tie rod is connected with the two trapezoid arms. The left steering knuckle and the right steering knuckle are fixedly connected with hubs of two rear wheels respectively. The rear wheel steering reversal mechanism comprises a hydraulic reversal cylinder, a motor, a rear wheel steering machine, a steering rocker arm and a rear wheel steering pull rod. The motor, the rear wheel steering machine, the steering rocker arm and the rear wheel steering pull rod are sequentially connected. The steering knuckle arm connected with the rear wheel steering pull rod moves to drive the rear wheels to steer, and the other steering knuckle arm is connected with a piston rod of the hydraulic reversal cylinder. The chassis achieves the four-wheel steering function of a commercial vehicle and meanwhile is simple in structure and small in control difficulty.

The invention provides a multi-monomer directly equalizing device and method of a series battery pack, and relates to a monometer equalizing circuit of the series battery pack. The multi-monomer directly equalizing device and method of the series battery pack solve the problems that direct energy transfer between any two energy storage monomers can not be achieved, the energy equalizing path is long and the energy equalizing efficiency is low according to an existing energy equalizing device between the energy storage monomers. The series battery pack is formed by series connection of m+n monomer batteries. The multi-monomer directly equalizing device comprises a transformer and m+n bilateral switches, wherein the transformer is provided with m+n windings, the first m energy storage monomers in the series battery pack are used as the first group, and the last n energy storage monomers in the series battery pack are used as the second group; m coils in the m+n windings of the transformer are in one-to-one correspondence with the m energy storage monomers in the first group respectively, and the rest of the n coils are in one-to-one correspondence with the n energy storage monomers in the second group respectively; the m+n windings share one magnetic core, and the number of turns of the m+n windings is equal, so the energy direct transfer between any two energy storage monomers can be achieved. The multi-monomer directly equalizing device and method can be applied to the field of energy equilibrium of the series energy storage monomers.

The invention discloses a calibration method and system applying a camera and scene association of intelligent driving. The method comprises steps of monitoring a single or multiple target objects in the camera view field in advance through a camera which is arranged on an automobile windshield and has an adjusted view angle; when each target object walks in the camera view field, carrying out imaging through the camera, and using the position and height information, detected by a detector, of each target object in an image coordinate as calibration data; and according to the calibration data, through offline calculation or online learning, updating a calibration model used for representing the position and height relations of the target objects. According to the invention, by calibrating the target objects appearing in the camera view field through the camera installed on the automobile, structure distribution properness of pictures and targets in the imaging pictures are mainly calibrated; and the calibration method is advantageous in that the calibration method is simple, rapid, accurate and free of environment limitations.
