Patent EP-0403055-A3 (EP)
IPC: G01P3/48
Filed: 1990-04-18
Abstract: A process for maximizing the instruction 
processing efficiency of a digital computer for the 
purpose of calculating rotational speed wherein the 
calculation of speed is based upon speed signals 
generated by a tachometer. By (1) counting the 
quantity of the speed signals received during a fixed 
sampling period, and (2) recording the occurrence 
time of these speed signals only as necessary for 
the calculation of rotational speed, the invention 
improves over known methods in that it does not 
record the occurrence time of all speed signals, but 
rather records the occurrence time of only those 
speed signals necessary for the calculation. The 
invention accomplishes this by a) anticipating when 
the speed signals necessary for the speed calculation 
will be generated (and subsequently received by the 
digital computer) and b) recording the occurrence 
times only when it is anticipated that these 
necessary edges will be received by the digital 
computer.

Title: Combined range laser scanner
IPC: G02B26/10
Filed: 1991-12-30
Abstract: A combined range laser scanner and method for 
electro-optically reading indicia such as bar codes having 
parts of different light reflectivity which utilizes two 
laser diode optical illumination systems optimally focused 
for different working ranges. A first laser illumination 
system is optimized for contact operation and has a range 
extending to approximately two feet. The second laser 
illumination system is optimized for longer range scanning 
from approximately two to seventeen feet, and the two laser 
scanning systems are integrated into one combined range 
laser scanner. The combined range laser scanner 
incorporates therein logic circuitry which enables either 
laser illumination system as required fro the particular 
scanning application. Depending upon which laser 
illumination system is selected, the laser spot speed (e.g. 
amplitude of the drive signal for the scanning motor) is 
controlled to limit the frequency of received light signals 
to that of standard signal processing and decoding circuits. 
Scanning is achieved with a common oscillating mirror 
element driven by a scanning motor, and the amplitude of the 
applied scanning motor driving signal is greater for the 
first laser illumination system optimized for contact or 
short range operation and less for the second laser 
illumination system for longer range scanning.
