Abstract: An air/fuel ratio control system and method for correcting the air/fuel ratio for each of N cylinders in an internal combustion engine (12) having electronically actuated fuel injectors (31,32,33,34) coupled to each cylinder. first air/fuel controller (16) provides a desired fuel command for maintaining an average air/fuel ratio among the cylinders in response to an exhaust gas oxygen sensor and a measurement of inducted air flow. A second air/fuel controller (18) generates N trim signals by sampling the exhaust gas oxygen sensor once each combustion period, synchronising the samples to generate N nonperiodic samples, correlating the samples with the corresponding combustion event and integrating. The fuel command to each fuel injector (31,32,33,34) is then trimmed for operating each cylinder at a desired air/fuel ratio.

Abstract: So that the distance between workpiece and nozzle in laser cutting machines can be detected in a contactless manner, the change in the capacitance is measured. To this end, it is necessary to arrange the electrically conductive metallic nozzle (1) in a receptacle (10) designed as an insulating body, an electrically conductive connection (13, 14) being provided between the nozzle (1) and the measuring device. In order to provide a receptacle (10) which is simple to produce and ensures an easy-running thread and good contact transmission between nozzle (1) and receptacle (10), an insert (4) made of an electrically conductive material, in particular metal, and having the internal thread (6) for the nozzle (1) is inserted into the recess (9).

Abstract: An external cavity laser is formed by feeding back light from a laser (102, 150, 202) through two or more acoustooptic tuneable filters (AOTF#1, AOTF#2, 210) back to the laser. The Doppler shifts introduced by the filters do not entirely cancel. The net Doppler shift caused by the filters is continuously tuned to cause the bandpass of the filter to follow the shifting resonating frequency of the laser to prevent mode hopping.

Abstract: Strands (24) on which metal parts (22) to be coated are divided off by preformed separating points (26) are guided only loosely in a section (44) upstream of a mould cavity (20), are advanced as far as a stop (60) in the mould cavity (20) and subjected to a pushing force, by which they are bent in the form of a sinuous line to form a length in reserve in the section upstream of the mould cavity (20). Then, the forwardmost metal part (22) of each strand (24) is fixed in the injection mould (18). Only after fixing of the respectively forwardmost metal part (22) is the pushing force interrupted; when this occurs, the strands (24) are released for their length in reserve to move back. Subsequently, the strands (24) are clamped in place again and broken off at their forwardmost separating point (26). In this way, spacing tolerances between the separating points (26) are prevented from accumulating to become errors which would prevent a severing of the strands (24) at the respectively forwardmost preformed separating point (26). <IMAGE>

Abstract: A system is proposed for bidirectional electromagnetic transmission of data signals between at least two fixed stations and one mobile station. The fixed stations transmit the data signals to the mobile station synchronously in downlink mode, their carrier frequencies being different. The data signals are transmitted in uplink mode according to the semi-passive transponder principle from the mobile station to the fixed stations. The data signals of the mobile station are frequency-modulated at the different carrier frequencies of the fixed stations. This arrangement achieves an improvement in the reliability of the bidirectional data transmission. A preferred use is for data exchange for systems controlling traffic between fixed beacon devices and moving vehicles. <IMAGE>
