摘要:
The present disclosure relates to a diesel exhaust treatment device including a catalytic converter positioned upstream from a diesel particulate filter. An electric heater is positioned between the catalytic converter and the diesel particulate filter. A shore station can be used to provide power and combustion air to the diesel exhaust treatment device during regeneration of the diesel particulate filter.

摘要:
An amplifier applies a self-adapting voltage to an output terminal. A bias circuit provides a greater bias current in a first external connection condition, in the absence of a pull-up resistance connected to the output terminal, than when such a pull-up resistance is present. The amplifier applies a different voltage to the output terminal in the absence of a pull-up resistance than when such a pull-up resistance is present. The circuit can be used in a portable device for receiving charging current from a battery charger through a connector having a D+ pin for connection to the battery charger and connected to the amplifier output terminal for battery charger detection. The portable device can meet the USB battery charger specification rev. 1.2.

A method and apparatus for allocating subcarriers in an orthogonal frequency division multiple access (OFDMA) system is described. In one embodiment, the method comprises allocating at least one diversity cluster of subcarriers to a first subscriber and allocating at least one coherence cluster to a second subscriber.

摘要:
Error correction techniques based on a modified chase combining (MCC) in data retransmission in communication systems such as wired and wireless communication systems. The described MCC may be implemented in wireless communication systems that use hybrid automatic repeat request (H-ARQ) in data transmission. In wireless systems, the mobile communications devices and base stations may be designed with the present MCC.
