Abstract: A vehicle brake system, includes a brake fluid control assembly and a brake master cylinder assembly. The brake fluid control assembly a manifold block, and a pressure buildup device mounted at the manifold block. The brake master cylinder assembly is in communication with the manifold block. The brake master cylinder assembly and the pressure buildup device drive brake fluid to be output via the manifold block. A central axis of the brake master cylinder assembly is non-perpendicular to a first axis along a movement direction of a piston of the pressure buildup device.

Abstract: A brake system includes a brake master cylinder assembly that is configured to connect to a brake pedal, and includes a master cylinder housing and a master cylinder piston being moveable inside the master cylinder housing and defining a compression chamber inside the master cylinder housing. A displacement sensor is mounted on the brake master cylinder assembly. An electro-hydraulic assembly is disposed separately from the brake master cylinder assembly, the electro-hydraulic assembly and the brake master cylinder assembly are connected by a connecting oil pipe and are in communication by a brake fluid in the connecting oil pipe, and the electro-hydraulic assembly is configured to connect to a wheel brake. A controller is connected to the displacement sensor and the electro-hydraulic assembly, and controls, according to an action of the brake pedal or a brake command, the electro-hydraulic assembly to output the brake fluid to the wheel brake.

Abstract: A portable rapid detection device for heavy metal ions includes a card electrode and a thin-layer flow cell, wherein a three-electrode system of the card electrode is inserted in a micro-channel of the thin-layer flow cell; and heavy metal ions are detected by using an anodic stripping voltammetry (ASV), a solution to be detected flows by the surface of a working electrode in the micro-channel, and heavy metals are enriched and stripped on the surface thereof.
