Symmetrical/asymmetrical bidirectional S-shaped I-V characteristics with trigger voltages ranging from 10 V to over 40 V and relatively high holding current are obtained for advanced sub-micron silicided CMOS (Complementary Metal Oxide Semiconductor)/BiCMOS (Bipolar CMOS) technologies by custom implementation of P₁-N₂-P₂-N₁//N₁-P₃-N₃-P₁ lateral structures with embedded ballast resistance 58, 58A, 56, 56A and periphery guard-ring isolation 88-86. The bidirectional protection devices render a high level of electrostatic discharge (ESD) immunity for advanced CMOS/BiCMOS processes with no latchup problems. Novel design-adapted multifinger 354/interdigitated 336 layout schemes of the ESD protection cells allow for scaling-up the ESD performance of the protection structure and custom integration, while the I-V characteristics 480 are adjustable to the operating conditions of the integrated circuit (IC). The ESD protection cells are tested using the TLP (Transmission Line Pulse) technique, and ESD standards including HBM (Human Body Model), MM (Machine Model), and IEC (International Electrotechnical Commission) IEC 1000-4-2 standard for ESD immunity. ESD protection performance is demonstrated also at high temperature (140° C.). The unique high ratio of dual-polarity ESD protection level per unit area, allows for integration of fast-response and compact protection cells optimized for the current tendency of the semiconductor industry toward low cost and high density-oriented IC design. Symmetric/asymmetric dual polarity ESD protection performance is demonstrated for over 15 kV HBM, 2 kV MM, and 16.5 kV IEC for sub-micron technology.

An MRI-compatible electronic medical therapy system is provided for temporarily preventing current flow through an implanted lead wire in the presence of an induced radio frequency, magnetic, or static field. One or more normally closed switches are disposed in series between the AIMD and the one or more distal electrodes. The switch may be incorporated in the AIMD, lead wire, or within or adjacent to the electrode. The switch remains closed during normal AIMD-related therapy, but temporarily opens in the presence of an induced radio frequency, magnetic, or static field so as to prevent current flow through the electrode and lead wire. The switches prevent current from circulating that could be induced by a medical therapeutic diagnostic device, which can cause overheating of lead wires, excessive currents or temperatures and tissue damage.

A device for controlling a steer-by-wire steering system in a vehicle is described. The redundantly generated sensor signals (deltav1, deltav2, deltaH1, deltaH2) for regulating a steering motor (LM) and for a feedback actuator (LRM) that transfers the restoring torques from the road to the driver via the steering wheel are received by a control device having the form of a microcomputer (RM) and plausibility checks of the sensor signals are performed therein and in an operatively associated monitoring module (ÜM).

Processors that encrypt frames of data representing images and sounds, for example, use a first encryption process to encrypt control data that includes selected data from the data frames and use a second encryption process to encrypt non-selected data from the data frames. The first encryption process is responsive to a key, which may be associated with an intended recipient of the data frames. The second encryption process is responsive to a key that is obtained or derived from the control data. The encrypted control data and the encrypted non-selected data may be delivered to a receiver using separate media. The receiver recovers the data frames using decryption processes that are inverse to the first and second encryption processes. Efficient implementations of the second encryption process are disclosed.

A silicon-on-insulator (SOI) gated diode and non-gated junction diode are provided. The SOI gated diode has a PN junction at the middle region under the gate, which has more junction area than a normal diode. The SOI non-gated junction diode has a PN junction at the middle region thereof, and also has more junction area than a normal diode. The SOI diodes of the present invention improve the protection level offered for electrical overstress (EOS)/electrostatic discharge (ESD) due to the low power density and heating for providing more junction area than normal ones. The I/O ESD protection circuits, which comprise primary diodes, a first plurality of diodes, and a second plurality of diodes, all of which are formed of the present SOI diodes, could effectively discharge the current when there is an ESD event. And the ESD protection circuits, which comprise more primary diodes, could effectively reduce the parasitic input capacitance, so that they can be used in the RF circuits or HF circuits. The proposed gated diode and non-gated diode can be fully process-compatiable to general partially-depleted or fully-depleted silicon-on-insulator CMOS processes.

A compressor casing with a volute-shaped flow duct is fastened by means of a rigid fixing arrangement to the bearing casing of the turbomachine, with simple and low-cost means in such a way that the emergence of fragments of a burst compressor impeller from the compressor casing can be prevented. The compressor casing has an outer spiral casing, which surrounds a duct section of the flow duct deflected towards the outside into the radial direction (B), and an inner casing insert piece, which is provided in the radial direction (B) between the spiral casing and the compressor impeller and whose inner contour, together with the outer contour of the hub of the compressor impeller, forms the duct section of the flow duct extending essentially in the axial direction (A). The spiral casing is configured with an inner cylinder at least partially surrounding the casing insert piece, on which inner cylinder the casing insert piece is attached by means of a fixing arrangement, which is flexible in the axial direction (A), to form a hollow space. The flexible fixing arrangement of the casing insert is less secure against fracture than the rigid fixing arrangement of the compressor casing on the bearing casing.
