摘要:
The use of a control module having at least one housing part and a multi-layer printed circuit board as the electrical connection between the inner space of the housing and components that are situated outside of the housing part is described. The multi-layer printed circuit board is the carrier for the electrical components of an electronic circuit, and is at the same time the thermal contacting to a housing part and/or a cooling element, particularly a hydraulic plate of the transmission, for a transmission control installed in an automatic transmission.

An electrical control unit has a printed circuit board substrate, on which an electronic circuit is situated, which circuit includes multiple electrical components which are interconnected via printed conductors of the printed circuit board substrate, as well as housing parts for covering the electrical components on the printed circuit board substrate, and at least one device plug connector part situated on the printed circuit board substrate outside the section of the printed circuit board substrate covered by the housing parts. Outside the section covered by the at least one housing part and outside the section of the printed circuit board substrate provided with the device plug connector part, at least one contact point for an additional electrical component is situated on the printed circuit board substrate.

A method and a device are for predicting a life expectancy of a product, which includes at least two components. The life expectancy is ascertained as a function of an assumed field loading of the product. The components of the product are acted upon by different loadings and are operated, in each instance, at the different loadings until they fail. An end-of-life curve of the component is recorded on the basis of the load-dependent failure times of a component. An EOL curve of the product is ascertained such that at the different loadings, it includes the EOL curve of the components which has, in each instance, the shortest failure time at the corresponding loading. The anticipated service life of the product is determined as a functional value of the EOL curve of the product as a function of the predefined loading of the product.

摘要:
A yarn traverse-winding apparatus of a textile machine producing cross-wound bobbins has a given traversing width and an endless yarn traversing belt. The belt has a belt body, yarn drivers spaced apart along the belt body, and inlays spaced apart within the belt body at intervals smaller than the given traversing width. The inlays are individually detectable by a sensor aimed at the yarn traversing belt.
摘要:
A quick-change picture frame, which for changing the picture has to be opened only at one corner and wherein miter cut elastic moldings are connected by a loosenable corner connecting piece at one corner and by firmly attached corner pieces at all other corners. Within the molding grooves are provided into which the edges of the corner pieces are fitted. The loosenable corner piece comprises a plate which is pivotably attached to the end section of one of the moldings, which form the openable corner, and has a guiding groove, which cooperates with a guide projection on the second molding of this corner in order to lock the corner piece when the frame is closed.
摘要:
A system with a transmitter for transmitting digital data via an interface to a receiver. The interface has at least one data line and a clock line. A clock generator supplies a clock signal to the clock line. The receiver uses the clock signal received from the clock line for deriving timing information for processing received digital data. The clock signal may have an amplitude that is lower than the power supply voltage VDD, typically less than half of the power supply voltage, and less stringent requirements can be applied to the waveform of the clock signal than traditionally applied to data and clock signals. The clock signals are hereby less power consuming and cause significantly less electromagnetic interference.
摘要:
Described is an ABS for vehicles in which all wheels are driven. Of particular concern is the forming of a final reference speed for the slip control. From the speeds of wheels with different speeds, an auxiliary reference speed, and a reference speed and a final reference speed for the slip control is formed . In the event of instability, however, the increase of the auxiliary reference speed determines the reference speed.
摘要:
Antilock control system generates an instability criterion from at least one of slip and deceleration of the wheels and produces control signals for reducing brake pressure at the wheels when the criterion exceeds an instability threshold. The system delays the criterion reaching the threshold, for example by increasing the threshold, when vehicle deceleration increases and when downhill travel is determined. The instability criterion S may be calculated according to S=aV+bL+c.intg.Ldt, where V is the wheel deceleration, L is the wheel slip, and a, b, and c are constants.
