Abstract: A DDR DRAM having a test mode and an operational mode and a method for testing the DDR DRAM. The method includes in the order recited: (a) placing the DDR DRAM in test mode; (b) issuing a bank activate command to select and bring up a wordline selected for write of the DDR DRAM; (c) writing with auto-precharge, a test pattern to cells of the DDR DRAM; (d) repeating steps (b) and (c) until all wordlines for write have been selected; (e) issuing a bank activate command to select and bring up a wordline selected for read of the DDR DRAM; (f) reading with auto-precharge, the stored test pattern from cells of the DDR DRAM; and (g) repeating steps (e) and (f) until all wordlines for read have been selected.

Abstract: A DDR DRAM having a test mode and an operational mode and a method for testing the DDR DRAM. The method includes in the order recited: (a) placing the DDR DRAM in test mode; (b) issuing a band activate command to select and bring up a wordline selected for write of the DDR DRAM; (c) writing with auto-precharge, a test pattern to cells of the DDR DRAM; (d) repeating steps (b) and (c) until all wordlines for write have been selected; (e) issuing a bank activate command to select and bring up a wordline selected for read of the DDR DRAM; (f) reading with auto-precharge, the stored test pattern from cells of the DDR DRAM; and (g) repeating steps (c) and (f) until all wordlines for read have been selected.

Abstract: In a throttle valve actuator unit having a throttle valve neck that contains a pivotable throttle valve and having a drive chamber for receiving an electric drive mechanism for the throttle valve and for receiving an electric connection plug for a plug connection to a control unit, in order to reduce the production costs while maintaining the many customer-specific characteristics, the drive chamber is enclosed by a housing module, and the throttle valve neck is attached as a separate part to the housing module and secured thereto.

Abstract: In a throttle valve actuator unit having a throttle valve neck (11) that contains a pivotable throttle valve and having a drive chamber for receiving an electric drive mechanism for the throttle valve (13) and for receiving an electric connection plug (20) for a plug connection to a control unit, in order to reduce the production costs while maintaining the many customer-specific characteristics, the drive chamber is enclosed by a housing module (12), and the throttle valve neck (11) is attached as a separate part to the housing module (12) and secured thereto.

Abstract: A measuring device for contactless detection of a rotational angle (&agr;) comprises a carrier plate (12), made of soft-magnetic material, which acts as a rotor. Two segments (15, 16) separated by a slit (17) are disposed in a plane parallel to the carrier plate (12). Disposed on one of the segments (16) is a short-circuit piece (20), and all these parts are of soft-magnetic material. The short-circuit piece (20) and the segments (15, 16) serve to guide the magnetic flux that is generated by a permanent magnet (13) disposed on the carrier plate (12). Since the short-circuit piece (20) protrudes past the carrier plate (12), or in a further feature the carrier plate (12) protrudes past the short-circuit piece (20), insensitivity to axial or radial play is possible. Furthermore, the measuring device is relatively simple and space-saving in design.
