Filed: 1989-10-06
Abstract: An antenna system (100) for an array antenna includes 
an array of radiators (102, 104) formed as patch antenna 
elements on a dielectric substrate (106), there being a shield­
ing metallic sheet (110) on a side of the substrate (106)

the feed system provides phase quadrature signals for develop­
ment of circularly polarized radiation. The crossover (74B, 
74T) provides only a linearly polarized wave, and is formed 
of two coplanar waveguides, one in the shielding sheet (110) 
and one in the bottom sheet (112). Each of the coplanar 
waveguides includes a pair of coupling pads, the pads of one 
waveguide being in registration with the pads of the other 
waveguide

Abstract: An improved valve assembly is provided for the distal end of a catheter (12), and particularly a central venous catheter for controlling fluid passage from the catheter to the blood flow passage in which it is inserted, and flow in the opposite direction. A relatively thin sheath wall (14) covers the distal fluid opening (25) of the catheter, and includes a slit (16) for responding rapidly to pressure differentials on either side of the slit opening to allow fluid passage, as required. In addition, the distal end of the catheter, and the side walls thereof adjacent the end, are covered by a thin sheath which serves to impart a small degree of thickness or "body" to the end of the catheter except at the opening thereof. More importantly, with the arrangement here the integrity of the catheter wall is far less compromised.

Title: Apparatus and method for extracting edges and lines
IPC: G06T5/00
Filed: 1990-03-22
Abstract: An apparatus and method for processing image data 
to derive edges and line segments. Image intensity 
data is processed in one dimension along a series of 
scan lines to produce an intensity curve (10). Pairs 
of points along a scan line curve (10) representing 
curvature extrema (20) are checked to determine if the 
intensity difference between the curvature extrema (20) 
are characteristic of edges. Edge points are then 
determined between pairs of curvature extrema. Edge 
points found between curvature extrema (20) are then 
correlated with other edge points in previous scan 
lines to determine if they fall within a range of 
predicted line segments. Line segment data may then be 
processed at higher levels to identify objects in the 
data.

roller and a return roller and gear train constantly 
driven by the rearward flywheel and pivotable 
thereabout between operative and inoperative 
positions. The driver is shiftable between a 
retracted position and an extended position A driver 
trigger (10) released locking means maintains the driver 
in its normal position. A driver actuator introduces 
the released driver between the flywheels. The tool 
has a safety (92) which controls the driver trigger, the 
driver actuator and the positions of the forward 
flywheel and the return roller.
