Title: Sampled servo motion control system
IPC: H02P25/06
Filed: 1989-03-28
Abstract: In a servo controlled device such as a disk drive actuator or a robot 
that is driven by a DC motor and must seek from one position to another 
position and settle at the target position in a minimum time, a deadbeat 
control response can effect settling in a minimum number of servo sample 
times with no steady state error and no ripple between sampling instants. 
The device design, initial conditions entering the deadbeat controlled 
mode and the frequency of servo samples can be used to enable deadbeat 
control by limiting the control current to a value that will not saturate 
the motor coil or exceed the linear operating range of the controlled 
device.

Title: Method and system for decompressing colour video encoded data
IPC: H04N11/04
Filed: 1989-04-26
Abstract: The method and system of decompressing color 
video data for use in a video information communication 
system utilizes digitized run length and color informa­
tion to represent the pixels in the scan lines of a video 
picture frame. The digitized signals are of a first 
digital word size, the run length portion of the digit­
ized signal is of a second digital word size and the 
color portion of the digitized signal is of a third 
digital word size. The run length portion and the three 
digital color components data are stored in an array in a 
memory to represent the pixels in the scan lines of the 
video picture frame; and the color portion of the 
digitized signal is converted into three digital color 
components of fourth, fifth, and sixth digital word 
sizes. The memory consists of a pingpong A buffer memory 
and a pingpong B buffer memory, from which the run length 
and color information is transferred to a display drawing 
engine which generates a series of converted digital 
color components representing individual pixels, which is 
then converted to analog form for display on a monitor.

Patent EP-0370679-A3 (EP)
IPC: G03G21/00
Filed: 1989-11-14
Abstract: An image forming apparatus comprises a memory (25) 
containing code data, code data input keys (12) and a 
preheat changeover key (11) for selectively switching 
a fixing device (81) to a preheat mode or an operation 
ready mode, whereby the apparatus is permitted to 
operate when a code data manually entered through the 
code data input keys (12) is identical with one of the 
code data already stored in the memory. The image 
forming apparatus further comprises entered code data 
release means adapted to be associated with the 
operation of the preheat changeover key (11) for 
switching the fixing device (81) to the preheat mode, 
so that the apparatus is brought to the state which 
prevailed before the code data is entered and where 
the apparatus is inhibited from operating. When the 
preheat key (11) is pressed, the apparatus is switched 
to the preheat mode and, at the same time, the entered 
code data is released. Accordingly, the apparatus 
requires no dedicated button or key for releasing the 
entered code data, and may put to practical use the 
preheat changeover means (11) which has been 
conventionally provided.
Patent EP-0371717-A3 (EP)
Title: Apparatus for reproducing digital audio and video data
IPC: G11B20/10
Filed: 1989-11-27
Abstract: Digital audio and video signal are recorded on 
successive oblique tracks formed on a video tape, and 
reproduced therefrom by reproducing heads which can be 
movable in a direction transverse to the tracks by means of 
a bimorph device so that at least a plurality of tracks 
including one field of video and audio signals are skipped 
in a variable tape speed mode. Track portions provided for 
the audio signal are arranged at both ends of the video 
tracks. In a mode in which the read head ships a field the 
signal level of the audio signal reproduced from one end 
portion of the audio tracks is gradually reduced at an end 
of tracking by the head, while the signal level of the audio 
signal reproduced from other end portion of a new field 
track portion is gradually increased so that a cross-fade 
function can be performed.

switching transistors (40, 48) is provided with output loading 
transistors (76, 78) to drive the two transistors (40, 48) into 
saturation in the event of a metastable condition causing input 
is present. By driving the switching transistors (40, 48) into 
saturation they become inactive and background noise cannot cause 
propagation of the metastable condition to subsequent flip-flop 
stages.

formed component to another tire building location .
Patent EP-0389811-A3 (EP)
Title: Image data processing system with adaptive binary quantization
IPC: H04N1/40
Filed: 1990-02-27
Abstract: An extractor (1, 21 to 23, 25) extracts, from image 
data to be binarized, a feature amount of a target pixel 
including at least a maximum density difference among 
pixels in a local region including the target pixel. 
A predictor (24) predicts an image type of the target 
pixel in accordance with a minimum density value among 
the pixels in the local region. A selector (24) selects 
one of the feature amount of the target pixel from the 
extractor (1, 21 to 23, 25) and a feature amount ob­
tained by adding the feature amount of the target pixel 
to feature data of neighboring pixels in accordance with 
the image type predicted by the predictor (24). A 
discriminator (24) discriminates the image type of the 
target pixel in accordance with the feature amount 
selected by the selector (24). A weighting section (28) 
weights the discrimination result from the discriminator 
(24) with respect to the neighboring pixels of a prede­
termined range preceding the target pixel in accordance 
with distances from the target pixel to the neighboring 
pixels so as to generate feature data of the neighboring 
pixels selectively used by the selector (24). A deter­
minator (3) adaptively determines a threshold value 
for binarizing the image data in accordance with the 
discrimination result. A binarizing section (7) 
binarizes the image data in units of target pixels by 
using the threshold value determined by the determinator 
(3).

Abstract: In a rectangular composting bed installation (1, 2) the material is spread in transversely extending heaps. A device (11-13) for spreading the material is arranged on a bridge (10) which extends transversely across the composting bed (2). A device (20, 21) to receive the material so that it can be shovelled into continuously new heaps is arranged on a second bridge (19) which extends transversely across the composting bed (2), the device (20, 21) being displaceable along the bridge (19). Both bridges can travel in the longitudinal direction of the composting bed (2), the first bridge (10) travelling beyond the second bridge (19). The former device (11-13) is supplied by a conveyor belt (4) which extends along the composting bed (2) and onto which the device (20, 21) for receiving the material delivers the said material via a conveyor belt (20) which extends along the second bridge (19). To spread the subsequent heaps after the first one, the former device (11-13) is arranged behind the device (20, 21) for receiving the material in the conveying direction of the first conveyor belt (4). This composting bed installation can operate in a variable, and therefore more efficient, fashion. <IMAGE>

Patent EP-0675657-A3 (EP)
Inventor: KLINK KRISTOPHER ALLYN
IPC: H04N5/46
Filed: 1995-03-18
Abstract: A composite video input signal is delayed by a delay
element (60) and the delayed composite signal is applied to
luminance and chrominance inputs (40,50) of a picture processor
(10) for received signals of an NTSC format. For received signals of a
PAL format, the delayed composite signal is applied only to the
luminance input of the picture processor and the chrominance
component of the received signal is transcoded (80) to the NTSC
format and applied, without passing through the composite signal
delay element, to the chrominance input of the picture processor. The
delay of the delay element for the composite video signal is selected
to be equal to the transcoding delay whereby luminance and
chrominance components of received signals of either NTSC or PAL
format are delay compensated. Advantageously, the delay applied to
the luminance component is constant and of the same value for
signals of either format and so there is no need for switching of delay
elements in the luminance path when changing from one format to
the other and so undesirable switching artifacts (e.g., DC offset or
transient effects) are avoided.
