Patent EP-0380033-A3 (EP)
Title: Circuit arrangement for a freely oscillating flyback switching power supply
IPC: H02M3/335
Filed: 1990-01-22
Abstract: The invention relates to a circuit arrangement for a freely oscillating isolating transformer switched-mode power supply having a control device (IC) for the pulse-width-modulated triggering of an electrical switching element (T1). As control information, this control device (IC) receives, inter alia, on an input terminal (8) a zero passage detector signal (Uzero) and, on a further input terminal (1), a control voltage (UR), which is dependent on the output voltage (UA) of the switched-mode power supply. In order to ensure reliable operation of the circuit arrangement, even in the event of low power consumption and especially in the standby mode with only a few watts no-load power, it is proposed to provide, in addition to a capacitive coupling of the two input terminals (1, 8), a detector device (DE) with whose aid an internal reference voltage (Uref) of the control device (IC) can be reduced in the standby mode. By this means, the increase in the output voltage, which is undesired in the standby mode and is increased even further by the capacitive coupling, can effectively be avoided.

IPC: G06F3/048
Filed: 1990-04-24
Abstract: An instrument ("INSTR") hardkey facilitates a change 
in settings of any instrument displayed in any of the 
windows that appears on a display. The user merely 
depresses the "INSTR" key and selects the instrument 
whose settings are to be changed by means of a softkey 
menu that is displayed when the "INSTR" hardkey is 
depressed. A color editor is preferably resident in the 
display and provides a superimposed window and softkey 
menu for enabling the user to adjust colors. An "Adjust 
Color" softkey allows the user to adjust one or all of 
six factors: red, green, blue, hue (tint), saturation 
(color or color level), and luminosity (brightness). The 
window preferably displays red, green, and blue bars in 
a bar graph format, which change in height as the user 
changes the red, green, and/or blue settings by means of 
a rotary pulse generator or a numeric keyboard. The 
window also shows readouts for hue, saturation, and 
luminosity which change as the user adjusts the values 
with the rotary pulse generator or the numeric keyboard. 
The ability to adjust any or all of the six attributes 
(red, green, blue, hue, saturation, and/or luminosity) 
enables the user to select any desired color. A method 
implemented in software, instead of hardware, also 
provides pixel stretching to the entire display to 
provide clearer, more refined images.

Filed: 1991-04-14
Abstract: The invention relates to a device for mounting and adjusting traffic installations and/or the lighting means thereof on traffic areas, for example in order to secure construction sites and hazard points in public traffic. Traffic installations of this type, in particular warning lights, are frequently carried by the police or other services in motor vehicles, usually cars. They have to be compact and, when used, are erected on the traffic area for securing purposes. In order to make the height of the light spot adjustable, when the traffic installation is erected on the traffic area, in such a manner that the emitted light signals or other information can be best seen by the road users, a moveable and adjustable connecting device is provided between the functional part (1), which supplies the information, and the supporting base part (3), which may contain the power supply device and the switch gear, this connecting device making it possible, after the erection of the base part (3) on the traffic area, to adjust the functional part (1) to a desired position. This connecting device is preferably designed as a telescopic rod (5) which carries the functional part (1) at the upper end as a provider of information. This telescopic rod (5) makes it possible to adjust the functional part (1) to a desired position, for example at approximately head height for a person sitting in a car. The information emitted by the functional part (1), for example optical signals, can thus be seen even at a relatively long distance in a queue of vehicles. <IMAGE>

Title: Auxiliary battery operation detection circuit
IPC: H02J7/00
Filed: 1991-10-04
Abstract: A power supply which senses whether a primary battery is discharging to below a predetermined dead battery level or the primary battery has been removed and the system is operating from an auxiliary battery, which has a lower voltage. When the battery voltage goes below the dead voltage level, the system is in a low power mode and the power supply output voltages are satisfactory, a timer may be started. If the battery voltage does not drop to the auxiliary battery voltage level within a predetermined time, a shutdown signal is generated and the power supply ceases providing output voltage levels. In this manner the primary battery can be removed and the system can continue running on the auxiliary battery until a charged primary battery is installed and yet the primary battery discharge rate will be greatly slowed when the primary battery voltage is below a given level and the primary battery is still installed in the system. <IMAGE>

Abstract: A method and apparatus for losslessly compressing binary data
using a technique referred to as Double Run-Length Encoding
(DRLE). DRLE has particular application to the compression of
gray-scale data as it is being processed for printing by a laser
printer or other continuous raster scan device. DRLE records
repeating patterns of ones and zeros with little computational
complexity. Compression ratios that may be an order of magnitude
or more are obtained frequently on data that may not compress well
using traditional Run-Length Encoding (RLE). DRLE uses a
sequential history of order-pairs that denote variable-length
patterns of zeros and ones, and then encodes these patterns as
they repeat themselves.
