Patent EP-0400607-A3 (EP)
IPC: G06T1/00
Filed: 1990-05-30
Abstract: An infrared monitoring system includes a 
histogram calculation circuit (30) which detects an 
alarm area having a plurality of pixels more than a 
threshold number (Nth) of pixels and having a 
temperature higher than a threshold temperature (Tth) 
and which generates a first alarm signal when detecting 
the alarm area. The infrared monitoring system also 
includes a shape recognition circuit (31) which 
determines whether or not a shape of the temperature 
change area corresponds to a predetermined shape and 
which generates a second alarm signal when determining 
that the shape of the temperature change area 
corresponds to the predetermined shape. An alarm 
device (33) included in the infrared monitoring 
system generates an alarm such as a siren when both the 
first and second alarm signals are generated. In place 
of or in addition to the shape recognition circuit, a 
temperature profile circuit (32) is used which 
determines whether or not a relative position of a 
pixel having a highest temperature contained in the 
temperature change area to a vertical width of the 
temperature change area is in a predetermined range and 
which generates an alarm signal when determining that 
the relative position of the pixel is in the 
predetermined range. The alarm device generates the 
alarm when the alarm signal from the histogram 
calculation circuit and at least one of the alarm 
signals from the shape recognition circuit and the 
temperature profile calculation circuits are 
generated.

Title: Method and device for determining surface structures
IPC: G01N29/04
Filed: 1990-06-08
Abstract: The methods known in optics for determining surface structures permit only a determination of the surface characteristic, but not the determination of the structures located closely underneath the surface. The subject matter of this application is to overcome this disadvantage of the known determination capabilities to the extent that not only can just the surface characteristic be determined by the method but also, at the same time, the structure underneath the surface to the depth of approximately one wavelength. Devices for carrying out the method are likewise proposed. To carry out this method, it is proposed that the object to be determined, which is resting on a flat or domed surface, be subjected to ultrasonic waves through a solid body or through a body filled with fluid and thus the waves which are scattered back and reflected as a result of the sound striking the object be recorded by a receiver, the wavelengths of the ultrasonic waves being matched to the structure of the respective object. Conclusions on the characteristics of the surface and of the deep structure can be drawn from the intensity of the waves which are scattered back and reflected. <IMAGE>

Title: System and method of load sharing control for automobile
IPC: F02D41/04
Filed: 1990-02-15
Abstract: A system and method for load sharing processing operations between 
a vehicle mounted station (105) and a stationary base station (25) having 
a large capacity host computer (18) is 
described. The vehicle mounted station (105) 
has detectors for determining operating conditions of a vehicle and 
controllers (3,4,501) for varying the operating conditions. The 
controllers (3,4,501) are connected to a 
transmitter-receiver (5) which is arranged 
to communicate over a path (10) with a transmitter-receiver (11) of the 
base station (25). The base station (25) has 
a host computer (18) having a large 
memory capacity. At predetermined intervals, for example, distance of 
travel or at engine stop, the vehicle transmitter (5) transmits operating 
conditions to the base receiver (11) for data processing and the base 
transmitter (11) then transmits processed data back to the receiver 
vehicle (5), whereupon the controllers (3, 4, 501) modify the vehicle 
operating conditons. The vehicle operating conditions may be an 
indication of life expectancy of fuel injectors or sensors, updating data 
processing maps. The presence of abnormal operating conditions may be 
detected by the vehicle mounted station (105), 
evaluated by the base station (25) 
and an emergency warning indication provided back to the vehicle mounted 
station (105), or if the abnormal condition 
is not of an emergency nature then 
counter measures are transmitted from 
the base station (25) to the vehicle mounted station (105).

Title: Hologram construction
IPC: G03H1/04
Filed: 1990-05-16
Abstract: The method involves directing first (B1) and second (B2) 
separate illuminating beams towards a photosensitive film (HP) from 
separate fixed apparent beam source positions (S1 and S2) 
respectively in such a manner that the beams are caused to overlap 
at the point of incidence at the photosensitive film (HP). 
Stationary interference fringes are generated and the beams are 
caused to scan in a raster type pattern over the photosensitive 
film in such a manner whereby overlapping of the beams (B1 and B2) 
is maintained throughout the exposure of the film. The apparatus 
in one embodiment involves the generation of a third illuminating 
beam (B3) which is used to control means (SC2) to control an 
associated scanner to effect synchronised movement of the second 
beam (B2) with the first beam (B1). A further embodiment involves 
memorising the scanning movement of beam (B1) in a memory (CM) and 
using the memorised scanning pattern to control the scanner (S2) to 
maintain beam overlap.

Title: Clamping device for workpieces destined to be processed on a machine-tool
IPC: B25B5/10
Filed: 1990-06-01
Abstract: A clamping device has a rectangular frame (1), to the longitudinal members (4, 5) of which clamping strips (7, 8; 107, 108) are fastened. Each clamping strip is provided with a plurality of tapped holes (15) which are widened to a predetermined nominal size. Thus bolts (17) pushed through in each hole (15), grub screws (22) screwed into the holes (15), or stop bars of nominal diameter can be used for clamping and positioning the workpieces (16, 19). Owing to the fact that the actual clamping can be effected by means of the clamping strips (7, 8; 107, 108), the frame (1) can be kept very light, since it is freed in particular from clamping forces. <IMAGE>

Title: Internal line up clamp.
Inventor: LEDUC TRUNG
IPC: B23K37/053
Filed: 1994-06-03
Abstract: An improved internal line up clamp (10) is disclosed which has an integral back up ring (12). A first set of pipe clamps (22) move radially outward to engage the inner surface of a first pipe (14). A second set of pipe clamps (62) and a set of back up ring segments (202) are simultaneously moved radially outward into engagement with the inner surface of the pipes. The back up ring segments (202) are spring loaded to exert a relatively constant back up force against the inner surface of the pipes at the weld. In a modification, a fill block (118) can be used to fill the gap between adjacent back up ring segments when engaging the inner surface of the pipe. The back up ring segments support the shoe elements (220). The shoe elements are spring loaded to accommodate diameter mismatch and non-circularity of the pipe ends. The back up ring segments rotate about a radial axis from the pipe centerline. Tapered ends on the back up ring segments provide for the decrease in ring circumference necessary to lower the ring segments. <IMAGE>
Patent EP-0640942-A3 (EP)
IPC: G10L21/10
Filed: 1994-08-30
Abstract: The graphics applications of a 2-D graphics computer system 
provide each object to be rendered on a 2-D raster display with a pair of 
rendering reference coordinates (x and y), and a relative depth value (z). 
Additionally, the computer system is provided with a library of predetermined 2-D 
images and sounds, and a number of graphics toolkit routines. As the user 
"moves", the graphics toolkit routines render selected ones of the 
predetermined images based on x/z and y/z values of recomputed x and y 
rendering coordinates and the relative depth value z of the objects, and actuate 
the sounds if applicable based on their predetermined manners of rendering. 
As a result, the objects that are further away from the user will move slower than 
the objects that are closer to the user, thereby introducing the effect of parallax 
and added realism to the 2-D graphics computer system at a substantially lower 
cost.

The displaying involves displaying the maximum Doppler power intensity of the locations on a spatial basis in a three dimensional presentation.
Patent EP-0732734-A3 (EP)
Inventor: FARB JOSEPH E
IPC: H01L29/80
Filed: 1996-02-12
Abstract: A method (40) of fabricating self-aligned static induction transistors (10) is
disclosed. The method (40) comprises fabricating (41) an silicon substrate (11) having
an active area 14a. A guard ring (15) is formed (43) around the active area. Source
and gate regions are formed, and a self-aligned relatively deep trench in accordance
with the present invention is formed over the gate regions. This is achieved by forming
(45) an oxide layer, and forming (46) a polysilicon layer on the oxide layer. A second
oxide layer is formed (47) on the polysilicon layer which is then masked (48) by a self-aligning
mask. Trenches 21 are etched (49) into the substrate using the self-aligning
mask and gate regions are formed (50) at the bottom of the trenches. The transistors
(10) are then processed to completion by forming gate, source and drain regions. This
portion of the method comprises the steps of forming (51) maskless self-aligned gate
metallization, forming (54) maskless self-aligned contacts to the gate metallization and
filling the trench, forming (55) source metallization, and forming (58) a drain contact
on the substrate. The present method (40) employs a single minimum geometry trench
mask. The key features of the transistors (10) are defined by the trench mask and
related processing parameters. Because of the self-alignment achieved by the present
invention, the number of channels per unit area is higher, which results in higher
transconductance. In addition, some parasitic capacitance is eliminated by the present
invention, resulting in faster operational speed. The variable sidewall trench oxide
thickness allows fabrication of static induction transistors (10) with higher or lower
breakdown voltages according to the thickness that is chosen, and for a more graded
gate junction.
