摘要:
A hybrid powertrain includes an electrically variable transmission and an internal combustion engine. The transmission is operable to provide a continuously variable mode of operation. The engine is capable of variable displacement in that at least half of the cylinders contained therein are deactivatable. Additionally the internal combustion engine operates with a late intake valve closing strategy to increase the peak efficiency of the internal combustion engine.

The invention relates to an exhaust-gas thermal conductor, comprising a tube array with exhaust gas flowing therethrough and cooling medium flowing around the same. The tube array is welded to a tube base, connected to the housing. As a result of varying temperature effects on the tubes and on the housing whilst operating the exhaust gas thermal conductor, thermal stresses, as a result of differing expansion of the tubes and the housing, occur. According to the invention, said stresses may be avoided, whereby slots are arranged in the housing sleeve, which are externally sealed by means of a bellows.

The invention relates to a magnetic arrangement for transmitting torque from an input shaft (1) to an output shaft (2), of for example a pump, whereby at least one magnet arrangement (3, 4) is assigned to the input shaft (1) and to the output shaft (2). A containment shell (5) comprising at least one inner sleeve (3) and at least one outer sleeve (4) extends between the magnet arrangements. According to the invention, the inner sleeve (3) is formed from at least one profile element (7) that extends approximately in the manner of a coil, whereby the outer sleeve (4) is provided for axially fastening the profile element.

A one-mode, input-split electrically variable transmission is provided with two motor/generators and a torque-transmitting mechanism that is operatively connected to a second member of a first differential gear set and selectively engageable to connect the second member of the first differential gear set with the stationary member, thereby establishing a fixed speed ratio between the input member and the output member of the transmission. Preferably, another torque-transmitting mechanism is also provided to lock any two members of the differential gear set to one another, thereby establishing a second fixed speed ratio between the input member and the output member.
摘要:
A phase error correction technique in data communication receivers such as WLAN (Wireless Local Area Network) receivers is provided. A signal having a phase error is received, and a phase error correction mechanism having a loop structure is operated on the input signal to correct the phase error. The corrected signal still has a residual phase error. The residual phase error is then compensated taking into account a loop time delay of the loop structure. Further, a phase change rate may be taken into account, and a smoothing process may additionally be performed.

The invention relates to an exhaust-gas thermal conductor (1), comprising a tube array with exhaust gas flowing therethrough and cooling medium flowing around the same. The tube array is welded to a tube base (5), connected to the housing (2). As a result of varying temperature effects on the tubes and on the housing (2) whilst operating the exhaust gas thermal conductor (1), thermal stresses, as a result of differing expansion of the tubes and the housing (2), occur. According to the invention, said stresses may be avoided, whereby slots (8-10) are arranged in the housing sleeve (2), which are externally sealed by means of a bellows.

The invention relates to a steering system (1) for a vehicle, comprising a shaft (4) that is rotatably mounted on a frame (3) in a bearing (2), said shaft being functionally linked with a steered wheel for adjusting the steering angle thereof, and a means (5) for axially positioning the shaft (4) in the frame (3). In order to allow for the shaft (4) of the steering system (1) to be free of backlash in an inexpensive and simple manner, the means (5) for axially positioning the shaft (4) is configured as a pressure pad (6) which is axially supported on the frame (3) and on the bearing (2) sitting on the shaft (4) without play and which retains the bearing (2) on the frame (3).

A wireless local area network receiver is provided that has an interference reduction unit for reducing interchip interference in a received signal that is modulated using a complementary code keying technique such as CCK-11. The interference reduction unit comprises a decision feedback equalizer that has a feedforward filter for reducing precursor interference and a feedback filter for reducing postcursor interference in the received signal. The receiver may perform channel estimation to optimize the filter coefficients during the preambles of the incoming sequence.
