Title: Distance measuring method and apparatus therefor
IPC: G01S13/28
Filed: 1989-08-07
Abstract: A distance measuring method and apparatus in which first 
and second pseudo random signals which are the same in pattern 
but slightly different in period are generated to obtain 
a correlation output of the first and second pseudo random 
signals before transmission thereof as a reference correlation 
output, and the first pseudo random signal is directly 
transmitted toward a target or alternatively a carrier wave 
is modulated by the first pseudo random signal and transmitted 
toward the target. A correlation output of the signal reflect­
ed and received from the target and the second pseudo random 
signal is detected and the distance to the target is measured 
from the time interval between the reference correlation 
output and the received correlation output. Alternatively, 
the modulated carrier wave reflected and received from the 
target and the second pseudo random signal are subjected to 
correlation processing to detect a correlative modulated 
carrier wave and the correlative modulated carrier wave is 
subjected to orthogonal detection by a reference carrier wave 
thereby obtaining a target detection output. Then, the 
distance to the target is measured from the time interval 
between the reference correlation output and the target 
detection output.

On receipt via the matching stage and amplifier 24 it is sampled by capacitor array 25 and detected in detector 29. Amplitude information from array 25 is made available to the microcontroller to compute time of signal travel and hence flow rates.
Patent EP-0389399-A3 (EP)
Title: Directory structure for worm optical media
IPC: G06F12/00
Filed: 1990-02-20
Abstract: A directory structure for WORM optical media which 
supports a multi-level tree structure containing several 
paths is disclosed. When a user defines the first path on 
the WORM volume, a first file directory group (140) is 
created for that path. A path directory entry pointing to 
this file directory group is written to the path directory 
group (130). Files having this path name are initially 
written into the first data file area (150) next to this 
file directory group. The first data file area grows as 
data is written into it. When a second path is defined, 
the first data file area is closed and a second file 
directory group (160) is created on the WORM volume next 
to the first data file area, thereby wasting little if any 
space. The path directory group is updated with a new 
path directory entry that points to this new file directo­
ry group. Files having this second path name are written 
into a growing second data area. If the user now wants a 
file having the first path name to be written to the disk, 
a file directory entry is placed in the first file direc­
tory group, but the file itself is written into the grow­
ing second data file area. In this manner, files are 
associated with directory entries by a common path name, 
not necessarily physical location on the disk, although 
files tend to be relatively close to their associated 
directory entry.

Patent EP-0548951-A3 (EP)
IPC: G06K7/10
Filed: 1992-12-23
Abstract: A scanning arrangement located within a scanning device which is operative for repetitively scanning indicia having parts of different light reflectivity, for example, bar code symbols, and more particularly, pertains to a novel scanning motor of the arrangement for enabling a scan element which is supported by a holder structure mounted on a mylar motor to implement angular oscillatory movements in a linear scan direction between a pair of scan end positions. Hereby, pursuant to the structure of the scanning device, the scanning arrangement is preferably mounted on a single printed circuit board located within a lightweight scanning device of a hand-held housing of gun-shaped configuration which may be readily held and manipulated by a user of the scanning device. The structure of the scanning motor and of the scanning arrangement which are mounted on a printed circuit board is considerably simplified through the construction of the various components being essentially of molded plastic material, and through the utilization of a mylar leaf spring which limits the end scan positions of a scan element or mirror which is oscillated by a read-start device including a permanent magnet mounted on an arm of the holder for the scan mirror.
