Patent EP-0364307-A3 (EP)
Title: Method and apparatus for displaying different shades of gray on a liquid crystal display
IPC: G02F1/133
Filed: 1989-10-16
Abstract: A method and apparatus are disclosed which provide a 
means for both spatially and temporally resolving the 
on/off states of a two-state display device such as a 
liquid crystal display to provide apparent shades of 
gray. A particular feature of this method is that the 
cycling between on and off states is not performed in a 
discernible pattern. Rather, a pseudo-random pattern is 
utilized which repeats only after many cycles. 
Additionally, when the method disclosed herein is 
utilized, adjacent pixels, when selected to display the 
same shade of gray, do not cycle on and off in 
synchronization, but rather utilize out-of-phase cycling 
patterns. This spatial resolution reduces perceived 
flicker in the display and provides a more stable image. 
In one embodiment, eight shades of gray are provided. 
The shades are generated by cycling individual pixels 
such that when averaged over time, they are: always off; 
on 20% of the time; 33% of the time; 40% of the time; 60% 
of the time; 67% of the time; 80% of the time; or, on at 
all times.

Patent EP-0384495-A3 (EP)
IPC: G11B33/14
Filed: 1987-02-20
Abstract: A rotary drive device comprises: a magnetic stator 
[26A, 26B]; a rotor structure attached to a drive shaft 
[22] of the device and including at least one 
electrical drive coil winding [25A, 25B]; positional 
detection means [31 to 35], including an encoded member 
movable rotatably with the said drive shaft, for 
providing monitoring signals dependent upon the 
rotational position of the drive shaft with respect to 
the said stator when rotation of that shaft is brought 
about by energization of the said drive coil 
winding(s); and control means operable in dependence 
upon the said monitoring signals to control rotation of 
the said drive shaft within a preset restricted angular 
range.  
     Coil lead wires [125A-1, 125B-1], for supplying 
electrical current to the said drive coil winding(s) 
[25A, 25B], extend from the drive coil winding(s) 
through a substantially radial passageway [22c] in the 
said drive shaft, at a location substantially mid-way 
therealong, to an axial passageway [22b] therein and 
continue along that axial passageway to emerge from one 
end [22d] of the drive shaft. Respective ends of the 
drive coil lead wires [125A-1, 125B-1] that protrude 
from the said one end [22d] of the drive shaft [22] are 
connected to respective terminals [127a, 127b] provided 
on a terminal fixing unit [126] mounted on the said 
drive shaft at the said one end so as to rotate 
therewith.  
     In such a device the main coil lead wires are not 
directly subjected to repeated stress during 
oscillatory motion of the rotor, so that these lead 
wires are significantly less prone to fatigue-related 
failure, thereby improving reliability.

by the bias voltage generating circuit (43). The 
first-level signal generating circuit receives the pre­
determined second-level signal and generates the prede­
termined first-level signal on the basis of the first

Title: Serial data transmission
IPC: G06F13/42
Filed: 1990-09-11
Abstract: A serial data interface communicates data between a control processor (1) and one or more slave processors (2) via a serial bus (3). Typically the control processor (1) may be formed in a hand held or lap top computer and the slave processor (2) in a peripheral device for the computer. The control processor (1) transmits a clock signal over a clock line in the serial bus (3) to the slave processor (2). At the same time, control or data frames are transmitted from the control processor (1) to the slave processor (2) or data frames are transmitted from the slave processor (2) to the control processor (1). Each data frame has a control portion which indentifies the frame as a control frame or as a data frame, and following the control portion a plurality of data bits bounded by idle bits. Both the slave processor (2) and the control processor (1) free the data line for a change in the direction of data transmission during each idle bit. In a preferred example, each control frame includes as one of its data bits a select bit identifying the control frame as a slave select frame or as a slave control frame. Each slave select frame includes as a further one of its data bits a reset bit. When the reset bit takes one pre-determined value the transmission of the slave select frame to the slave processor (2) causes that processor to reset to a pre-determined state. Otherwise, the transmission of the slave select frame to the slave processor selects or de-selects the slave processor. Each slave control frame includes as one or more of its data bits data transmission parameters which set the slave processor (2) to read or write one or more data frames subsequent to the current control frame.

Filed: 1994-06-07
Abstract: A method for updating a system program in a switching equipment. Many known, program-controlled switching equipment have a system program deposited in read-only memories. For modifying the system program, a replacement of the read-only memories is necessary, as known. The method updates the system program without having to undertake interventions in the existing switching equipment. Proceeding from a data processing device, administration and maintenance orders are communicated to the administration and maintenance interface of the existing switching equipment, these administration and maintenance orders being misused for the purpose of transmitting an updated system program stored in the data processing device into the switching equipment and in order to reroute the program processing of the system processor located in the switching equipment onto the newly written system program.

Abstract: A compressed audio/video, A/V, receiver provides
A/V component timing reference signals (208,212,214,220,222)
(PTS's) coincident with reproduction of associated decompressed
component signals. Synchronization apparatus generates a
function of the difference (217-219) of occurring component audio
and video PTS's. This function, which is indicative of relative
audio and video synchronization, is compared with a
predetermined threshold value (225), and a mute control signal is
generated when the threshold is exceeded. Muting circuitry
(229), responsive to the control signal disables audio reproduction
when the reproduced audio and video component signal timing
deviate from mutual synchronization.

Abstract: Concomitant measurement of EtCO 2 , EtN 2  and (FiO 2 - FeO 2 ) concentrations are
used to detect a VAE. In a respiratory gas monitoring system, continuous

average for a predetermined time period. If the following conditions are met,
the device signals the presence of a venous air embolism: 1) a decrease in the
EtCO 2  concentration of 1.5 mm Hg; 2) an increase in the FeN 2  concentration of
0.03 vol%; and 3) a decrease in the difference between the inspired oxygen
