IPC: F02P19/02

Abstract: In a method for controlling the temperature of a spark plug, reference is made to a reference operating point. For this, a basic power value is determined which corresponds to the value of that power which is to be supplied to the spark plug so that the latter just reaches a desired temperature. If an actual operating point deviates from the reference operating point, the value of the difference of the current value with respect to the associated reference value as was present at the reference operating point is determined in each case for selected operating parameters. With the aid of this difference, a power change component is calculated for each operating parameter taken into consideration, by multiplying the associated difference value by an associated constant. The basic power value is modified by the calculated power change components. Preferably, an additional correction occurs taking into account the deviation of the actual speed of rotation from the speed of rotation at the reference operating point. This method has the advantage that, if an internal combustion engine reaches the reference operating point during practical operation, the spark plug temperature is set to the desired value with a high degree of accuracy. In the case of deviations from the reference operating point, only small errors occur with respect to the desired temperature and the temperature actually reached. <IMAGE>

Patent EP-0400755-A1 (EP)

IPC: H04B1/66
Filed: 1990-05-30
Abstract: A digital transmission system is disclosed having a transmitter (3,6,9) and a receiver (13,16,19) for transmitting a digital signal, such as a digital audio signal, having a given sampling rate F S . The digital signal is subband coded into M subbands with sampling rate reduction. To that purpose the transmitter includes a first unit (3) for splitting up the digital signal into M signals having a sampling rate F S /M. These signals are available at the outputs (4.1 to 4.M) of the first unit (3), and are applied to M analysis filters (6.1 to 6.M), each filter (6.m) having one input (5.m) and two outputs (7.ma and 7.mb). The 2M filter outputs are coupled to 2M inputs (8.1 to 8.2M) of a signal processing unit 9 which has M outputs (10.1 to 10.M) for supplying the M subband signals (S₁ to S M ) Each filter (6.m) is adapted to apply two different filterings on the signal applied to its input and to supply the two different filtered versions of the input signal to its two outputs. The signal processing unit 9 is adapted to supply output signals on each of the M outputs, an output signal being a combination of at least a number of input signals applied to its 2M inputs. On the receiver side a signal processing is carried out which is largely inverse to the signal processing on the transmitter side, in order to realize a signal at the output (21) that is a nearly perfect reconstruction of the input signal.
