Patent EP-0288421-A3 (EP)
Title: Symmetrisation of currents switched by gate-controlled semiconductors
IPC: H03K17/12
Filed: 1988-04-18
Abstract: For balancing the currents to be switched off of parallel-connected gate-controlled semiconductors having different turn-off or turn-off delay times, the actual turn-off or turn-off delay times of the semiconductors (V1, V2) are first determined at low currents. Then the delivery of the turn-off signals for the individual semiconductor (V1, V2) is in each case delayed, with currents increased up to the full operating current, by the time difference, determined during the preceding turn-off process, of its turn-off or turn-off delay time to the longest-lasting turn-off or turn-off delay time of one of the parallel-connected semiconductors (V1, V2). This delay can be additionally corrected in dependence on load current. <IMAGE>

Title: Cold-start engine priming and air purging system
IPC: F02M17/04
Filed: 1989-03-15
Abstract: A fuel delivery system for purging air from the reservoir (22) 
of a diaphragm carburetor (18) on an internal combustion engine and for 
supplying priming fuel to the carburetor air intake (26). An manual pump 
(12) has an inlet coupled by a fuel line (16) through the carburetor 
reservoir to a fuel supply (20), and an outlet connected by the fuel 
line to a constant flow rate nozzle orifice (24) positioned at the 
carburetor air intake. A pressure switch (36) is connected in the fuel 
line between the pump and orifice and provides a signal, in the form 
of a switch closure, to priming control circuitry (46) whenever fuel, as 
distinguished from air, is pumped through the orifice to the carburetor 
air intake. 
The control circuitry receives battery power through the pressure 
switch contacts, and includes an integrator (50) for accumulating total 
time of fuel flow and thereby indirectly indicating the total quantity 
of priming fuel supplied through the constant-flow orifice. When 
the integrated time duration exceeds a selected threshold, an LED (58) 
is driven by an oscillator (56) to advise the operator to terminate the 
manual priming operation. Most preferably, the time-duration 
threshold is varied as a function of engine temperature.

Title: A method and circuitry for automatic control, according to the counter principle, of the frequency of a radio telephone
IPC: H03J7/06
Filed: 1989-06-20
Abstract: The invention relates to a method and circuitry for auto­
matic control of the frequency of a radio telephone, ac­
cording to the counter principle and on the basis of the 
reception frequency, in which case the reception frequency 
(fin) is mixed with the output frequency of a phase-locked 
loop (7) in a first mixer (1), the output frequency (if1) 
of the first mixer (1) is mixed in a second mixer (2) with 
the frequency derived from a local oscillator (5), and the 
frequency of the phase-locked loop (7) is controlled on the 
basis of the frequency deviation of the output frequency 
(if2) of the second mixer (2). Whereas in prior-art cir­
cuitries at least two oscillators are needed, one of which 
must additionally be very precise, in the present invention 
one local oscillator (5) suffices, which is an oscillator 
having a controllable frequency and is controlled on the 
basis of the said frequency deviation, the reference fre­
quency (fr) of the phase-locked loop (7) being derived from 
the frequency (f) of the local oscillator (5). The frequen­
cy deviation of the second mixer (2) can be determined, for 
example, by counting pulses within a certain time interval, 
the time interval being determined by counting a certain 
number of pulses of the local oscillator (5).

Filed: 1990-10-19
Abstract: The contrast or absolute brightness of a multiplexed LCD is maintained at its preselected value using a feedback arrangement which includes an LCD element functioning as a reference element. The reference element is not used to display information but is continually driven ON and OFF. The average transmissivity of the ON and OFF states is determined and compared with a reference value, the result of the comparison being used to control the voltage levels of the drive waveforms applied to the LCD. By selecting appropriate ratios between the ON and OFF times of the reference element, the LCD can be operated to give optimum contrast, or may have its absolute brightness varied. Control may be effected remotely by reprogramming the microprocessor which determines the timing of the drive waveforms.

Title: Method for filing and retrieving data sets in a subscriber database
IPC: H04Q7/38
Filed: 1991-06-14
Abstract: Subscriber databases having a high fluctuation in subscriber data require special strategies to ensure, on the one hand, the greatest possible utilisation of the existing storage space but, on the other hand, also to keep the access times as short as possible. According to the invention, it is proposed to map an arbitrary subset of an arbitrarily large set of subscriber data to virtual control elements to which storage areas of the database are allocated via logical control elements. These storage areas allocated in this manner are, in turn, subdivided into smaller sub-areas, so-called pages. Using a small configuration table, it is possible to find the storage space allocated to a subscriber identification with only a few search steps. The average number of search steps is 4 to 6 with a memory utilisation of 80%. <IMAGE>
