The invention relates to a method for monitoring thermal runaway of a lithium ion battery of an electric vehicle. A voltage changing rate parameter when thermal runaway occurs in the lithium ion battery is monitored, and a battery voltage can be reduced abruptly, is maintained at a low voltage for 40-60 seconds and then is gradually raised to an initial voltage when the thermal runway occurs in the lithium ion battery; the fact that thermal runaway occurs in the battery can be judged by taking the battery voltage changing rate parameter as a monitoring object and is a first judgment method; abattery temperature rising rate changing parameter is monitored, the fact that thermal runaway occurs in the battery also can be judged when the battery temperature rising rate is larger than or equalto 10 DEG C per minute and is a second judgment method; and a battery management system (BMS) is used for monitoring, analyzing and judging the battery voltage changing parameter and the battery temperature rising rate parameter, the two methods are used as an independent condition or a logic combination condition and used as a technological basis for judgment on thermal runaway of the battery, and an early-warning signal can be given out in advance when thermal runaway occurs. By the method, the battery thermal runaway judgment time is greatly increased, and enough handling time is providedfor a person to escape and timely take a measure to prevent battery thermal runaway from being generated, propagating and being expanded.

The method is suitable for complex scenes with coexistence of multiple kinds of jamming, such as chaff jamming, noise jamming, range gate pulling off jamming and outboard dragging; the method has the advantages of low calculation complexity, great instantaneity and rapid and effective jamming identification; radar signal processing system hardware does not need extra circuit modules, and algorithms are simple; the method can be applied to engineering practices conveniently.

A transfer circuit includes a plurality of cascaded latch circuits. Two consecutive latch circuits in the transfer circuit complementarily enter a latching state and a transparent state in response to the applied clock signal, and data/a signal is transferred through the transfer circuit in response to the clock signal. A clock control circuit is provided for controlling an operation of each of the latch circuits. The clock control circuit detects that the latch circuit in a next stage of the corresponding latch circuit enters the latching state to permits transfer of the signal/data of the corresponding latch circuit to the subsequent stage in accordance with the corresponding clock signal. It is possible to prevent the data/signal from being transferred while the latch circuit at the next stage is in the transparent state to accurately transfer the data/signal. A clock synchronous data transfer and processing device reliably preventing racing is implemented with a simple circuit configuration.

The present invention provides providing predictable scheduling of programs using repeating precomputed schedules on discretely scheduled and/or multiprocessor operating systems. In one embodiment, a scheduler accesses an activity scheduling graph. The activity scheduling graph is comprised of nodes each representing a recurring execution interval, and has one root, one or more leaves, and at least one path from the root to each leaf. Each node is on at least one path from the root to a leaf, and the number of times the execution interval represented by each node occurs during the traversal of the graph is equal to the number of paths from the root to a leaf that the node is on. Each node has associated with it an execution interval length, and is adapted to being dedicated to executing the threads of a single activity. There may be one scheduling graph for each processor, or a scheduling graph may traverse multiple processors. Start and end times for reservations and constraints are adjusted to compensate for the granularity of the clock of the system. Furthermore, the scheduler may use an existing priority-based scheduler in order to cause scheduling decisions it has made to be acted upon.

In a method for determining at least one physical parameter, a sensor unit which is activated by at least one periodic excitation (1.4) is provided, wherein the sensor unit has at least one detection region in which changes of the parameter in the surroundings of the sensor unit lead to output signal (1.7) from the sensor unit. The sensor unit is wired such that if there are no changes of the parameter in the detection region the output signal (1.7) is a zero signal or virtually a zero signal at the output of the sensor unit, whereas if there are changes of the parameter in the detection region the output signal (1.7) is a signal that is not zero and has a specific amplitude and phase. In a closed control loop, the non-zero signal in the receive path is adjusted to zero using a control signal to achieve an adjusted state even in the presence of changes of the parameter in the detection region. The control signal is evaluated in order to determine the physical parameter. The output signal (1.7) from the sensor unit is reduced substantially to the fundamental wave of the excitation (1.4) and the output signal (1.7) is controlled to zero in the entire phase space by means of at least one pulse width modulation. A temperature-stable, fully digital measuring system is provided as a result of the fact that the at least one pulse width modulation itself generates a correction signal with a variable pulse width and possibly a variable phase which is then added to the output signal (1.7) from the sensor unit and the output signal is thereby controlled to zero in the entire phase space, wherein the pulse width of the correction signal and/or the phase of the correction signal is/are determined by the deviations of the output signal (1.7) from zero.
