A rheostat includes a connection port, a variable resistor, a controller and a display. The connection port is electrically connected to a computer and configured for receiving a control signal of the computer. The variable resistor is electrically connected to a circuit board. The controller is electrically connected to the connection port and the variable resistor and is configured for changing a resistance value of the variable resistor according to the control signal. The display is electrically connected to the controller and displaying the resistance value.

Embodiments provide systems, methods, and integrated circuits having a calibration structure with a calibration component and a measurement structure coupled to the calibration component. The measurement structure is configured to vary a current through the calibration component until a voltage of the calibration component equals an operation voltage. The variable current is a function of at least the operation voltage and a resistance of a resistor external to the measurement structure.
摘要:
A device for activating a control unit is proposed. It includes at least one operating element operable by a user as well as analog encoding means assigned to the operating element. To generate an activation signal for a control unit, deactivation means are provided that deactivate at least one analog encoding means in order to digitally encode the operating element.

The device for compensating a weak cooling/overcooling for a cooling chamber of a refrigerator has a plurality of resistances connected in series between the power and ground and a plurality of switches connected in parallel to the plurality of resistances. A microprocessor receives a voltage divided according to an open/close state of the plurality of switches through a single input terminal. The device performs a weak cooling/overcooling compensation operation.

A device for activating a control unit is proposed. It includes at least one operating element (31 through 34) operable by a user as well as analog encoding means (21 through 24) assigned to the operating element (31 through 34). To generate an activation signal for a control unit (20), deactivation means (41 through 44, 51 through 54) are provided that deactivate at least one analog encoding means (21 through 24) in order to digitally encode the operating element (31 through 34).
摘要:
Automotive vehicle electronic devices are diagnosed through communication with a flexible diagnostic tool which automatically switches between a wide variety of communications protocols as required for diagnostic communication tasks presented to the tool. Simultaneous communication with a plurality of devices under a plurality of communications protocols is supported by the tool wherein communication hardware is available for parallel communications under the various protocols via various communication channels and is apportioned for each active diagnostic communication task for the duration of that task.
