Title: Switching power supply
IPC: H05B39/04
Filed: 1989-03-02
Abstract: A switched-mode power supply for a light source whose brightness is controlled, having a rectifier which produces a half-wave rectified voltage at first terminals, having a smoothing circuit which produces a smoothed DC voltage at second terminals, having two push-pull semiconductor switches, associated with a high-frequency generator, whose control inputs are each coupled to a transformer winding, and having a first switching element, which is coupled to the DC voltage input and is voltage-dependent, for triggering a semiconductor switch. The technical problem is producing a switched-mode power supply which permits brightness control by controlling the high-frequency generator without the high switching loads of phase chopping. A control input is fed via a first switching stage (81). A capacitor (44) with an adjustable load resistor (46) is connected to the second terminals (54, 55) of the DC voltage. The charging voltage of the capacitor (44) is applied to the input of a second switching stage (43) whose output switches off the first switching stage (81) and the voltage-dependent first switching element (15). A zero-voltage identifying circuit (56) is connected to the first terminals (5, 6) of the half-wave rectified voltage. The output of the zero-voltage identifying circuit (56) controls a discharge stage (57) for the charging capacitor (44). <IMAGE>

Title: Circuit for synchronizing transitions of bits in a digital code
IPC: H03M1/14
Filed: 1989-02-06
Abstract: An electronic circuit contains a main stage (10 
and 12) that produces a digital code consisting of a plurali­
ty of bits (B₀ - B M-1 ) that make binary transitions as a 
function of an input parameter (V I ). A synchronization 
stage (14 and 16) synchronizes transitions of bits 
(B₀ - B K-1 ) in one part of the code with corresponding 
transitions of bits (B K  - B M-1 ) in another part. When the 
input parameter is in transition regions where bits in the 
first-mentioned part of the code could go to wrong values, 
the synchronization stage suitably replaces the values of 
bits in the first part with information based on bits in 
the other part.

Title: Anti-aliased font translation
IPC: G09G5/24
Filed: 1990-05-31
Abstract: A method of generating a second, substantially anti-aliased, 
representation of a character from a first representation is disclosed. 
The second representation is comprised of horizontal lines of dots that 
are shifted horizontally relative to dots of the first representation, 
each dot of the first representation having a value DOT1 associated 
therewith. The method include a step of, for each horizontal line (1-m) 
within the first representation of a character and for each dot (1-j) 
within a horizontal line, determining a modifying value (DOT1k) 
associated with a dot(k) of the first representation, DOT1k being a 
function of DOT1 of the dot(k). The value (DOT2k) of a corresponding 
dot for the second representation is generated, the value of the 
corresponding dot being determined in accordance with the expression 
DOT2k = (( DOT1 - DOT1k ) + DOT1(k-1) ), where DOT1(k-1) is a modifying 
value of an adjacent dot on the horizontal line. The modifying value is 
preferably determined by a table look-up procedure within a table of 
previously generated values.
