摘要： A vehicle wheel monitoring device includes a tire pressure monitoring unit, a tire pressure sensor unit disposed at a wheel of the vehicle and a brake pad wear sensor unit disposed at a wheel of the vehicle. The brake pad wear sensor unit includes a brake pad wear sensor and a wireless transmitter configured to receive the signal emitted from the brake pad wear sensor and wirelessly transmit it to the tire pressure monitoring unit. An energy harvesting device is configured to convert energy derived from an external source into electrical power, and to provide the electrical power to the brake pad wear sensor unit and the transmitter. The brake pad wear sensor unit and the tire pressure sensor unit are monitored by the tire pressure monitoring unit.

摘要： An electromechanical brake system capable of conducting a brake pad wear check includes a structure defining a chamber, a member that rotates with a wheel, a motor mounted to the structure, a reciprocating piston, a brake pad, and a controller. The piston is driven by the motor between a variable actuated position and a retracted position. The brake pad is movably supported by the structure, operatively coupled to the piston, and adapted for braking contact with the member when the piston is in the actuated position, and spaced from the member when the piston is in the retracted position. The controller controls reciprocation of the piston between the actuated and retracted positions via energization of the motor, performs a brake pad wear check by calculating a change in a parameter associated with a change in distance between positions, and compares the change in parameter to a threshold value.

摘要： A mount is provided for fastening a contact conductor of a brake pad wear monitoring device of a disc brake, in particular of a commercial vehicle, on a brake caliper. The contact conductor is secured in a cable guide, which bears against a retaining bracket which extends across a mounting opening of the brake caliper. The cable guide is covered by a cover. The cable guide and/or the cover have at least one spacer element which is arranged in an intermediate space accommodating the contact conductor and bounds the height of the latter.

摘要： The present invention relates to a time-temperature indicator for monitoring the quality state of a thermally sensitive article and a monitoring method. The present invention also relates to a preparation method of the time-temperature indicator and a thermally sensitive article using the time-temperature indicator. The time-temperature indicator according to the present invention comprises two laminated layers which are physically separated, i.e. a function indication layer and an adsorption function layer. The two laminated layers are stored and transported separately, and combined together in use. Therefore, the time-temperature indicator of the present invention can be stored and transported at room temperature, which reduces the usage costs of the time-temperature indicator.

摘要： The brake indicator is a cylindrical device, measuring approximately one quarter of an inch in length and three-eighths of an inch in width. This component is a high temperature insulator pressed part with a round rod, as well as a wire configuration with terminal rubber booth protection. The wiring serves as the communication conduit between the brakes and the dashboard panel control inside the vehicle. The brake indicator assembly's sensor rod is positioned flush with each brake pad. Thus, the sensor rod will have contact with the rotor every time the brakes are depressed. As such, the indicator sensor rod will touch the rotor behind the brake pad before the pad wears down enough for a metal-on-metal contact. When the sensor rod touches the rotor, the wiring activates the warning light on the vehicle's dashboard, thereby informing the driver of the potential problem.

摘要翻译： 制动指示器是一个圆柱形装置，长度约为四分之一英寸，宽度为八分之三英寸。 该部件是具有圆棒的高温绝缘体压制部件，以及具有端子橡胶支架保护的导线配置。 该布线用作车辆内的制动器和仪表板面板控制器之间的通信导管。 刹车指示器组件的传感器杆与每个刹车片平齐。 因此，每当制动器被按下时，传感器杆将与转子接触。 因此，指示器传感器杆将在刹车片后面接触转子，然后垫片足够磨损金属接触。 当传感器杆接触转子时，接线会激活车辆仪表板上的警告灯，从而通知驾驶员潜在的问题。
