Title: Method and apparatus for determining the distances between surface-patches of a three-dimensional spatial scene and a camera system
IPC: G01C3/08
Filed: 1988-11-11
Abstract: The present invention concerns a method of 
determining the distance between a surface patch of a 3-D 
spatial scene and a camera system (1). The distance of the 
surface patch is determined on the basis of at least a pair 
of images, each image formed using a camera system (1) with 
either a finite or infinitesimal change in the value of at 
least one camera parameter. A first and second image of 
the 3-D scene are formed using the camera system which is 
characterized by a first and second set of camera 
parameters, and a point spread function, respectively, 
where the first and second set of camera parameters have at 
least one dissimilar camera parameter value. A first and 
second subimage is selected from the first and second 
images so formed, where the subimages correspond to the 
surface patch of the 3-D scene, the distance from which to 
the camera system, is to be determined. On the basis of 
the first and second subimages, a first constraint is 
derived between the spread parameters of the point spread 
function which corresponds to the first and second 
subimages. On the basis of the values of the camera 
parameters, a second constraint is derived between the 
spread parameters of the point spread function which 
corresponds to the first and second subimages. Using the 
first and second constraints, the spread parameters are 
then determined. On the basis of at least one of the 
spread parameters and the first and second sets of camera 
parameters, the distance between the camera system and the 
 
 
surface patch in the 3-D scene is determined. Using the 
distance finding method of the present invention, depth-­
maps of the scene are provided in real-time and in a 
computationally efficient manner. In addition, the present 
method is used to automatically focus the camera system and 
to generate improved-focus images.

Title: Apparatus and method utilizing lcd for printing
IPC: H04N1/40
Filed: 1990-06-29
Abstract: Method and apparatus which utilize an LCD modulator array for printing and/or enlarging an image recorded in a color film negative, a positive transparency or a color print, which LCD modulator array has pixels whose "closing time" (the time it takes to convert a pixel from a condition wherein it transmits radiation to a condition wherein it blocks radiation) is substantially longer than their "opening time" (the time it takes to convert a pixel from a condition wherein it blocks radiation to a condition wherein it transmits radiation). In accordance with the present invention, each pixel of the LCD modulator array is opened and closed in a rapid sequence, one after the other, at intervals which are much shorter than the closing time of the pixels of the LCD modulator array. The amount of radiation transmitted by each rapidly opened pixel is determined by detecting a spike of radiation which is transmitted through the rapidly opened pixel and by detecting and subtracting a background amount produced by radiation which is transmitted through other, slowly closing pixels.

Title: Iron with an electric heated soleplate
IPC: D06F75/26
Filed: 1990-11-02
Abstract: The iron comprises an electrically heated soleplate (3), the desired temperature of which is controlled by a thermostat (5) by the said thermostat periodically interrupting and restoring the power supply. The thermostat (5) can be set by means of an adjusting element (19). The iron is provided with a first and a second indicating element (23, 25), with in each case two indicating states (activated/non-activated). The indicating elements (23, 25) provide information on the actual temperature reached with respect to the desired temperature set. After turning the adjusting element (19), according to the invention the indicating state of the indicating elements (23, 25) is obtained from the turning direction of the adjusting element (19), from the operating state of the thermostat (5) before and after adjustment of the adjusting element (19) and from the old indicating state of the indicating elements (23, 25) before turning the adjusting element (19). As a result, an otherwise complex thermocouple, required in addition to the conventional thermostat (5), is not needed. <IMAGE>

Title: Signature analysis in physical modeling
IPC: G06F11/22
Filed: 1990-04-25
Abstract: In performing a series of device evaluation cycles relative to pins 
of a physical electronic model, a signature associated with an 
immediately preceding device evaluation cycle is compared to the 
corresponding signature that exists just prior to the last pattern for 
the current device evaluation cycle. If the signatures compare, the new 
pattern of the current evaluation cycle is completed. If the signatures 
do not compare, an error has occurred and the operator is notified so 
that this series of device evaluation cycles will not be considered 
valid. Computer simulation information is employed to determine the 
optimal times to clock signatures with each signal pin having its own 
programmable clocking circuit. These optimally generated signatures are 
used to verify the consistent operation of the physical model.
Patent EP-0398719-A3 (EP)
Title: Improvements in apparatus for particle determination in liquid metals
IPC: G01N27/00
Filed: 1990-05-17
Abstract: In apparatus for on-line particle determination in 
molten metals a sample of molten metal is drawn through a 
calibrated passage (22) while a steady current is established 
through the passage between two electrodes (12, 14) on opposite 
sides thereof. Particles moving through the passage produce 
voltage pulses whose magnitude and rate indicate respectively 
their size and number per unit volume. The wanted test signal 
can be obtained between the two current carrying electrodes (12, 
14), or between two other electrodes (15, 54) disposed on 
opposite sides of the passage. The electrodes (12, 14 or 15, 
48) form an interference-receiving antenna so that the wanted 
low signal/noise ratio test signal is overlaid with interference 
from neighbouring sources. This interference is reduced by a 
cancellation signal produced by a cancellation antenna 
constituted by a similar pair of electrodes (12, 15 or 48, 54), 
either separate from the main current-carrying electrodes or 
having one of them in common. A four electrode configuration 
permits the diameter of the passage to be monitored 
continuously. A five electrode configuration has three 
electrodes (15, 48, 54) separate from the current-carrying 
electrodes (12, 14) forming the two antennae and connected 
differentially. A further electrode (60) if provided is used to 
minimize ground loops in the signal path. A head member (70) 
carrying the tube (16) and electrode cluster (12, 14, 15, 48, 
54, 60) is mounted to move between operative and storage 
positions relative to a main body (72) member carrying the power 
supply (66); these are made symmetrical about a longitudinal 
axis so that interference signals are in anti-phase and cancel.
