A Q-Chip MEMS magnetic device comprises a thin-film electronic circuit for implantation in the Track-2 area of a magnetic stripe on the back of a credit card. The Q-Chip MEMS magnetic device periodically self-generates new sub-sets of magnetic data that are to be read in combination with other magnetic data that is permanently recorded in the surrounding surface of the magnetic stripe. A collocated battery and microcontroller provide operating power and new data for magnetic bit updates. A swipe sensor triggers such updates by sensing electrical contact with a legacy card reader. Several thin-film coils of wire are wound end-to-end around a common, flat, ferrous core. These are driven by the microcontroller. In one instance, such core comprises “hard” magnetic material with a coercivity of 200-300 Oersteds. Magnetic data written from the corresponding adjacent coils will persist for later readings by a legacy card reader. In another instance, the core comprises “soft” magnetic material with a coercivity of about one Oersted. A media stripe of “hard” magnetic film material overlays respective coils to receive magnetic data transfers. Magnetic data written from the corresponding adjacent coils will persist in the overlaying hard media for later readings by a legacy card reader. In a data input mode, the thin-film coils can be used as readers to provide updates and new programming to the microcontroller.

The present invention provides a single shell-pass shell-and-tube heat exchanger with helical baffles, where within a single pitch, the helical baffles are separated into inner and outer parts along the radial direction of the shell. In the central portion of the inner space of the shell, an inner non-continuous helical form is employed; in other portion outside the central portion, doughnut shaped helical baffles with continuous curved surfaces are arranged to form an outer continuous helical baffle, and the outer helical baffles are arranged to surround the inner helical baffles. Furthermore, the present invention relates to a multiple shell-pass shell-and-tube heat exchanger with helical baffles, in which complete continuous helical baffles are provided in shell-sides other than the inner shell-pass, while non-continuous helical baffles or other flow guide means are employed in the inner shell-pass.

A method for purifying the exhaust gas from an internal combustion engine, which is operated under lambda-based closed loop control and which has an exhaust gas tract in which is located a catalytic converter, is provided. According to this method, a pre-converter lambda value for the exhaust gas is continuously sensed upstream of the catalytic converter, from which a pre-converter lambda signal is generated, and this pre-converter lambda signal is used as the reference variable for the lambda control loop. A post-converter lambda value for the exhaust gas is continuously sensed downstream from the converter, from which a post-converter lambda signal is generated, this being a monotonically decreasing function of the lambda value for the exhaust gas downstream from the catalytic converter. The post-converter lambda signal is used in a trimming control loop to apply a correction to the lambda control loop, whereby a measurement signal is generated which, at least below a certain value of lambda close to lambda=1, is a strictly monotonically increasing or monotonically decreasing function of the lambda value for the exhaust gas downstream from the catalytic converter. For levels of the post-converter lambda signal which are above a threshold value, this supplementary measurement signal is used for trimming control. For levels of the post-converter lambda signal which are below the threshold value, the post-converter lambda signal itself is used for trimming control.
