摘要:
A method and device for monitoring and controlling the regeneration of a particle filter in an exhaust gas duct of an internal combustion engine which has a three-way catalytic converter downstream of the particle filter, wherein the particle filter is regenerated by oxidative burning of the particles during a regeneration phase, wherein oxygen consumption is balanced, directly or indirectly, during the regeneration phase via the temporal variation of a first signal of a first lambda probe, which is arranged upstream of the particle filter, in comparison to the temporal variation of a second signal of a second lambda probe, which is arranged downstream of the particle filter. A lambda value of λ=1 is set downstream of the three-way catalytic converter during the regeneration of the particle filter by means of lambda control and the second lambda probe which is arranged downstream of the three-way catalytic converter.

An apparatus and a method for cooling a super conducting machine are disclosed, in which at least two condenser areas each make thermal contact with a cold head, and in which the at least two condenser areas each have a connecting line, via which the at least two condenser areas are connected fluidically to an evaporator area. A liquid cooling fluid can be moved or pumped from at least one condenser area into the evaporator area by way of a temperature difference, and a pressure difference associated therewith, in the at least two condenser areas.

A method for generating a trigger signal for a magnetic resonance measurement by an R wave of an EKG signal is proposed. The EKG signal is captured by an algorithm manager. The algorithm manager includes at least a first trigger instance having a trigger algorithm. EKG signals from at least two different EKG channels are processed by the trigger algorithm. The algorithm manager includes at least a further trigger instance for capturing the EKG signal. The further trigger instance has at least one further trigger algorithm for processing EKG signals from at least two different EKG channels. The trigger signal is generated by selecting a trigger instance from the different trigger instances.

In a method for functional testing of a mechanical vibration sensor, a vibration signal is generated on the vibration component of the vibration sensor with the aid of a periodic excitation signal, the frequency of which excitation signal is varied, and a post-vibration process of the vibration component of the vibration sensor is analyzed once the excitation signal has been switched off.

Techniques are disclosed relating to prefetching data from memory. In one embodiment, an integrated circuit may include a processor containing an execution core and a data cache. The execution core may be configured to receive an instance of a prefetch instruction that specifies a memory address from which to retrieve data. In response to the instance of the instruction, the execution core retrieves data from the memory address and stores it in the data in the data cache, regardless of whether the data corresponding to that particular memory address is already stored in the data cache. In this manner, the data cache may be used as a prefetch buffer for data in memory buffers where coherence has not been maintained.

The present invention relates to a method for improving the corrosion-protecting pre-treatment of metal surfaces and using rinse water in a manner to conserve resources in such a corrosion-protecting pre-treatment, comprising a conversion treatment step using an aqueous composition comprising at least 50 ppm of the elements B, Si, Ti, Zr and/or Hf in the form of water-soluble compounds at a pH value of 3 to 5.5, wherein a minimum fraction of 10 ppm of the elements B, Si, Ti, Zr and/or Hf in the form of water-soluble compounds is present in the last pre-rinse step and a portion of the aqueous composition of the conversion treatment step is contained in the first post-rinse step. The resource-conserving use of the rinse water is accomplished according to the invention by way of a cascaded return of rinse water from the last rinse step to the first rinse step. The present invention also relates to a metallic component treated using the method according to the invention and to the use thereof in a process for applying a multi-coating system, in particular a paint system containing an organic binder, in industrial manufacturing.

摘要:
Monitoring aging information for multiple devices. Aging information of the devices may be received. Statistics regarding the multiple devices may be determined based on the aging information. For at least some of the devices, update information may be determined based on the respective aging information. The update information may include modifications to operating parameters of the devices. For example, the devices may operate according to initial parameters that are above sustainable parameters and the update information may lower the operating parameters based on the aging information.
摘要:
Adjusting a phase locked loop (PLL) clock source to reduce wireless communication (e.g., radio frequency (RF)) interference within a device. The PLL may be included in a high speed serial interface, e.g., coupled to a display, and may be initially driven by a first clock. Later, when a second clock is available and aligned with the first clock, the PLL may be driven by the second clock. The second clock may be configured to change its frequency over time such that the PLL does not lose lock and also does not interfere (or reduces interference) with wireless communication of the device. For example, the second clock may be programmable or may dynamically vary its operating frequency, thereby reducing its interference with the wireless communication of the device.

A superconducting machine for supporting a coolant feed line for superconducting machines includes a hollow shaft that can be connected to the superconducting machine in a first region, the coolant feed line being disposed in the interior thereof for feeding the coolant from the refrigeration unit to the superconducting machine. A magnetic support is disposed in the first region of the hollow shaft so that a radial and thus motion-damping, centering force is exerted on the coolant feed line. The magnetic support has a first and a second magnetic cylinder, wherein the first magnetic cylinder is disposed on the outer jacket of the coolant feed line and the second magnetic cylinder is disposed on the inner face of the hollow shaft. The first magnetic cylinder is a cylinder made of highly electrically conductive material having ohmic resistance.
