pixels is resolved by determining the edge of 
intersection between the planes of such polygons and 
testing the signs of certain values in accordance with 
predetermined criteria. Subpixel priority is treated 
for similar resolution to provide improved antialiased 
images.

Title: Improved method and apparatus for coin sorting and counting
IPC: G07D3/14
Filed: 1989-08-15
Abstract: This is a coin sorting and counting apparatus 
for providing very accurate high throughput processing of 
heterogeneous coin mixtures. A rotating drum having 
parallel annular channels, each of which has equally spaced 
counterbores located around it is rotated within a vacuum 
plenum. A novel sensor coil constructed as a balanced 
transformer of four coils having rectangular geometries is 
used, in conjunction with a dual frequency excitation signal, 
to detect at least three electronic signatures for each coin, 
the signatures are detected by separating the frequency 
components in the output of the sensor coil and obtaining a 
peak value for the excursion of the high frequency response 
caused by passage of the coin, and width values 
corresponding to the time the excursion of the signal was 
above a predetermined threshold for both the high and low 
frequency responsive channels. Based on the denomination 
determined, appropriate signals are inserted into a coin 
ejection memory queue which is shifted in synchronism 
with rotation of the drum. The memory queue is 
constructed so that an appropriate air valve will be activated 
when the detected coin is over an appropriate one of a 
plurality of coin receiving stations. A set of lag sensors are 
used downstream from the coin ejecting air valves to 
confirm proper ejection of the coins. Separate calibration 
values for the signature signals are acquired and saved for 
each counterbore location to offset the effects of variations 
in circuitry on a channel-by-channel basis and slight 
mechanical irregularities in movement of the counterbores 
past the sensor array.

Title: Weighing apparatus
IPC: G01G19/12
Filed: 1989-09-08
Abstract: A weighing apparatus for a vehicle (15) 
having tines (16) in which a ramp (60) is mounted on 
each tine (16) in front of and in spaced relation to 
a weighing load bearing plates (40). The ramp (60) 
and the confronting weighing load bearing plates (40) 
are not mechanically joined. Below each weighing 
load bearing plates (40) are load cells (21) for 
emitting changes in signals representative of the 
weight of a load on the weighing load bearing 
plates (40). As the load advances toward the 
weighing load bearing plates (40), the ramps (60) 
attenuate excessive forces and shock resulting from 
the load advancing onto the weighing load bearing 
plates (40). As a consequence thereof, the load 
cells (21) are not subject to the excessive shocks or 
forces of an advancing load.

between the base value and the new detected signal 
latched in a latch circuit (5).
Patent EP-0381901-A3 (EP)
IPC: H01L21/331
Filed: 1989-12-29
Abstract: A bipolar transistor (200) exhibits improved function due 
to its emitter structure. A single layer of conductive 
material (240) forms both the emitter contact (210) and the base contact 
(236) in the transistor (200) structure, which structure has particularly 
shallow emitter and base junctions (about 0.15 micrometer or less). The 
self-aligned emitter contact (210), isolated from the base contact (236) 
by a dielectric-filled trench (234), permits overall size reduction of the 
device, whereby junction area and accompanying leakage across junctions 
is reduced. In addition, when the structure of the bipolar transistor 
(200) is such that the dielectric-filled trench (234) isolates the emitter 
(212) area from both the base contact (236) and the extrinsic base (224), 
it is possible to provide improved base conductivity without generating 
peripheral transistor effects. The bipolar transistor (200) can be either 
N-P-N type or P-N-P type depending on the materials of fabrication, 
although high speed devices are typically of the N-P-N type.
Patent EP-0336821-A3 (EP)
Title: Cache memory system for computer use
IPC: G06F12/0842
Filed: 1989-03-30
Abstract: Associated for use with central processors 
(e.g. several function units) and a main memory, a 
cache memory system holds information units available 
to the processor more quickly than from the main 
memory. The cache is accessed directly with virtual 
addresses and includes an additional field for a key 
designation for distinctly identifying the pertinent 
program involving associated units of information. The 
difficulty of virtual addresses is that two virtual 
addresses in two different contexts may be the same but 
do not correspond to the same physical location. Thus, 
the additional field in the cache indicates whether the 
virtual address found is the one looked for. Structure 
is provided for purging the cache in a timely fashion 
to accommodate newly assigned keys.
