Patent DE-19912832-A1 (DE)
Title: Engine air-fuel ratio control unit inputting NOx and oxygen signals for quantitative regeneration of NOx absorption catalyst
Inventor: YAMASHITA YUKIHIRO
IPC: G01N27/407
Filed: 1999-03-22
Abstract: The exhaust sensor (26) signals exhaust NOx concentration (first signal) and exhaust air/fuel ratio (second signal). The signal analyzer (33) selects one signal for output, to control engine air/fuel ratio using an air fuel/ratio controller (31). PREFERRED FEATURES:- The controller (31) outputs the first or second signal, during lean and rich engine operation respectively. Further variants are described, with key features as follows. Continuous monitoring by a transition detector (33) determines transition from lean-to-rich ratio, from the first signal. The reverse transition is detected from the second signal. Based on the results, the controller adjusts the air-fuel ratio. The controller includes lean and rich controllers maintaining air/fuel ratio under rich control, to displace NOx absorbed by the NOx storage catalyst (13) during lean burn operation. The controller assesses the NOx stored during lean burn; it then controls fuel injection during rich operation, in correspondence with NOx absorbed, to precisely displace it. The sensor is a composite type, giving both NOx and oxygen concentration as first and second signals respectively.

Patent EP-1128546-A1 (EP)
Inventor: IPEK MEHMET
IPC: H03D7/14
Filed: 2000-02-28
Abstract: The upconverter mixer circuit comprises a Gilbert cell with
an LC-resonator (L1, C1) tuned to the output frequency of
the upconverter mixer circuit, and an output buffer. In a
preferred embodiment the output buffer comprises a
differential amplifier being emitter degenerated with
inductances (L2, L3) for a low-pass characteristic. The LC-resonator
of the Gilbert cell as well as the inductances of
the output amplifier are integrated in an integrated circuit
together with the other parts of the upconverter mixer
circuit and provide a first selection within the integrated
circuit for the subsequent stages, for example an
intermediate frequency filter of a double conversion TV
tuner. When the upconverter mixer circuit is operated with a
strong DC-current and hard switching, which is necessary for
achieving low noise, strong high frequency parasitic
currents are also generated. These are mainly harmonics of
the local oscillator frequency, which can be observed on the
supply lines and input and output lines of the integrated
circuit. The two stages of the upconverter mixer, the
Gilbert cell followed by the output buffer, provide
therefore a first intermediate filter to suppress parasitic
currents within the upconverter mixer circuit. This enables
to design a receiver with a large dynamic range and a high
linearity, and having a low noise, by using a strong DC
current and a hard mixer switching.
