Abstract: A process for determining a setpoint rotational speed of a work machine engine, having a continuously variable transmission, based on operation of power hydraulics. The setpoint rotational speed for highly productive operation is determined, without knowledge current operation of the power hydraulics, by a basic engine speed setting. With knowledge of the current operating state, the setpoint rotational speed is determined by the basic speed settings and low or high engine speed settings. The low speed setting alone determines setpoint rotational speeds that are lower than the basic speed setting or a combination of the low and basic speed settings. The high speed setting alone determines setpoint rotational speeds that are higher than the basic speed setting or a combination of the basic and high speed settings. The speed settings can comprise a setpoint rotational speed range of above a reciprocal transmission range of the variable transmission.

The method further includes ascertaining, when the load function is activated, a setpoint value for a lift position, a setpoint value for a tilt position, and a setpoint value for an accelerator pedal actuation as a function of a pressure measurement value on a hydrostat side of a power split transmission of the work machine, and ascertaining actuating signals for the automated or automatic loading as a function of a comparison of the ascertained setpoint values with corresponding actual values.

Abstract: A method of controlling a continuously variable transmission for a vehicle. The continuously variable transmission has a hydrostat with a position-regulating valve and is designed to co-operate in driving connection with a drive input shaft and a drive output shaft such that when the position-regulating valve is energized, the hydrostat is adjusted to accelerate the vehicle. The method includes monitoring the energization of the position-regulating valve cyclically by a safety function. The safety function is provided in order to recognize undesired energization of the position-regulating valve that leads to unwanted acceleration of the vehicle, and then to separate the transmission at least from the drive output shaft so as to prevent unwanted acceleration of the vehicle. The safety function is triggered at least when a limit value for the energization of the position-regulating valve is exceeded.

Abstract: A receiver or preamplifier for differential signals, in particular electrocardiogram signals, includes n electrodes to provide at least one signal at an acceptable common mode rejection ratio, even if the subject to which the electrodes are applied has a different ground potential than the assigned monitor. This is achieved by two current sources which are controlled by a sum signal representing a sum of the electrode signals, said current sources injecting a corresponding current into the electrodes.

Abstract: In a four element modified bridge circuit for measurement purposes at least one impedance element is variable according to a magnitude to be measured. Via a first operational amplifier a DC supply voltage is connected across two bridge nodes facing each other, and at the other two nodes facing each other an output signal is delivered corresponding to the magnitude to be measured. By means of a second operational amplifier one of the output nodes is virtually drawn to ground so that the signal at the second output bridge node is referenced to ground. Thus, the signal at the second output node corresponds to the desired measured magnitude without a superimposed power supply voltage and may be amplified by a third standard operational amplifier without the need of a differential amplifier circuit.
