Abstract: Techniques are described that can solve the problem of being low power while running a device on battery and alternatively running on the output of a switching regulator. In a low power mode, a voltage regulator circuit can be powered down and a switch can connect an input voltage of the regulator, e.g., a battery, to the CPU. In addition, internal and/or external loads, such as voltage feedback resistors, can be disconnected in order to further reduce the power consumption. If the device is going into operation, the CPU can be disconnected from the input voltage of the regulator, e.g., the battery, and switched to the output of the regulator. This can ensure that the circuit consumes very little power consumption in standby mode.

Abstract: A measuring system for registering the absolute rotation angle of a rotating, measured object, wherein a first gear is associated with a shaft of the measured object, wherein the first gear directly or indirectly engages at least a second gear and a third gear and wherein tooth counts the individual gears differ from one another.

Abstract: A coating device (10) for coating a metal strip (12) in a metal melt (14) includes a shaft (16,18) that is rotatable in the metal melt (14) for guiding the metal strip (12), and a slide bearing (261, 262) for supporting the shaft (16,18). The slide bearing (261, 262) is formed by a bearing housing (32) and a bearing bushing (34) that has several pairs (361–364) of bearing surfaces and is configured so as to be circumferentially closed. The bearing bushing (34) is adapted to be set in selected rotational positions in circumferential direction in the bearing housing (32). A releasable bearing bushing fixing element (40) locks the bushing in each of the selected rotational positions with respect to the bearing housing (32). Thereby, a worn pair (361–364) of bearing surfaces can be simply replaced by a non-worn pair (361–364) of bearing surfaces by a rotation of the bearing bushing.
