Abstract: A threshold safety sensor for a sliding door system employs 
infrared transmitters and a photo diode for detecting traffic at 
or near the threshold of a sliding door system. The transmitters 
are pulsed in a time spaced sequence. An input signal derived from 
the operate initiating signal of the automatic door operator is 
employed for enabling a latch. The latch sets a relay to a state 
for maintaining the doors in an open position when traffic is 
detected in the sensor detection zone.

Patent EP-0327004-A3 (EP)
IPC: F16H61/08
Filed: 1989-01-30
Abstract: Disclosed is a shift control for an automatic transmission 
adapted to shift speed ranges by coupling or decoupling 
of the friction coupling elements (20-27) mounted on the 
transmission mechanism (10).  
     The coupling force of the friction coupling elements (20-27) 
is subjected to feed-forward control during a preset period 
after a signal of instruction for shifting was given. 
A control value for the feed-forward control is determined 
in accordance with control value characteristics which 
vary from a given initial value at a constant change rate.  
     After the preset period, coupling force of the friction 
coupling element is feedback controlled by actual revo­
lutions of an input shaft (1) of the transmission mechanism 
(10). A final control value for the feedback control is 
determined by determining a target change rate in the 
feedback control by an amount of change in revolutions 
number of the input shaft (1) of the transmission mechanism 
(10) estimated by shifting and a set time for the feed-­
back control. With the target change rate, a target number 
of revolutions for each of plural control cycles obtainable 
by dividing the set time into portions is determined. 
For each of the control cycles, the final control value 
is determined by comparing the actual number of revolutions 
of the input shaft (1) and the target number of revolutions.

Title: Sawblade segments containing fine diamond or cubic boron nitride particles
IPC: B24D5/12
Filed: 1989-07-25
Abstract: The object of the invention is to provide saw blades having 
abrasive cutter segments which will wear non-uniformly so as to provide 
a concave wear surface and to thereby minimize blade path deviation, 
i.e. lateral vibration of the saw blade.  
     Figure 2 illustrates a preferred embodiment of a cutting segment for 
use on saw blades for cutting granite, marble, filled concrete and other 
hard materials. As can be seen, the concentration of diamond cutting 
elements (1) in the centre section (2) is preferably about the same as 
the concentration of diamond cutting elements (1) in the side sections 
or matrices (3). It should be appreciated, however, that a larger or 
smaller concentration of diamond cutting elements (1) can be employed in 
the centre section (2) without departing from the spirit or intended 
scope of the invention. For example, it is expected that in some 
applications it may be desirable that the concentration of diamond 
cutting elements (1) in the centre section (2) be greater than the 
concentration of diamond cutting elements (1) in the side sections (3). 
The most important consideration in the practice of the invention is 
that a non-uniform cutting rate be achieved by including an effective 
amount of abrasion-resistant particles (4) in side sections (3). Saw 
blade segments manufactured with abrasion resistant particles (4) in 
side sections (3) will exhibit concave wear and will form a ridge on 
stone workpiece (5) as shown in Figure 2. It is the presence of this 
ridge which minimize the ability of the saw blade to deviate from its 
cutting path.  
     Any suitable particles may be utilized as the abrasion-resistant 
particles (4). However, it has been found that diamond, CBN and tungsten 
carbide particles are particularly effective.  
     In general, the abrasion-resistant particles (4) should be less 
than about 80 mesh. Of course, the optimum mesh size for a particular 
application can be determined without undue experimentation. The 
concentration of abrasion-resistant particles can also vary depending 
upon the particular application, but a concentration of from about 0.10 
to about 0.35 carats per cubic centimeter has been found to be 
effective.

Title: Power transfer circuit including a sympathetic resonator
IPC: B42D15/10
Filed: 1989-03-10
Abstract: A power transfer circuit includes first and second windings (L1,L2) 
sharing a common magnetic core (101). Each winding (L1,L2) has associated with it 
a parallel capacitor (C1,C2) to thus form a pair of "tank" circuits. The first winding 
(L1) is connected at one end to a voltage supply and, at the other end, to ground 
through an FET switch (100,200). The switch (100,200) is turned on and off at a 
predetermined frequency and at a 50% duty cycle. The second winding (L2) and 
associated capacitor (C2) achieves parallel resonance at the predetermined frequency. 
Similarly the combined first and second windings (L1,L2) and associated capacitors 
(C1,C2) achieve parallel resonance at said predetermined frequency. The second 
winding (L2) need not be electrically connected to the first winding (L1) which 
transfers energy to it through the magnetic core (101). The transfer circuit efficiently 
couples power across a dielectric interface to a pickup coil (L3). One particularly 
good application of the power taansfer circuit is in connection with a contactless 
Smart Card.

them in end-to-end relationship in a tube (10, 61, 71). 
Tinted epoxy is inserted into the bore (12, 64, 74). 
One fiber is inserted into the bore until its endface 
reaches the center thereof. As the second fiber is 
inserted into the other end of the bore, the length of 
the epoxy column in the bore is observed to diminish as 
epoxy is displaced into venting means (14, 78) 
associated with the bore. When the second fiber 
begins to buckle, movement thereof is stopped. The 
central region of the tube is inspected to ascertain 
the disappearance of the epoxy column (54). This 
indicates that the endfaces are in abutment. The tube 
may contain an integral lens (65, 75) for viewing the 
fibers in the bore. A stripe of appropriate color

Title: Apparatus and method for documenting faults in computing modules
IPC: G06F11/20

Abstract: Method and apparatus for testing the operation of modules for use in a fault tolerant computing system that consists of two distinct computing zones. Diagnostic testing is performed when the system is powered on, the modules being subjected to module, zone and, if both zones are available, system diagnostic tests. Indications of faults detected during diagnostic testing are stored in an EEPROM on each module. Such fault indications can be cleared in the field by correcting the fault condition and successfully rerunning the diagnostic test during which the fault was detected. Indications of operating system detected faults are also stored in each module EEPROM. However, such fault indications are not field clearable.
