Title: Hierarchical data storage systems
IPC: G06F17/30
Filed: 1989-04-20
Abstract: A peripheral data storage hierarchy includes three storage levels. The 
top storage level is a fast accessing direct access storage device(s), 
such as magnetic disk drives. The intermediate level is an automatic 
warehouse type library, storing a large plurality of optical disks, 
which are automatically transferred between storage cells of the 
library and optical disk drives operatively connected to the host 
processor. The bottom level of the storage hierarchy includes one or 
more stand-alone optical disk drives and a shelf unit. Personnel 
manually carry the the optical disks between the stand-alone drives and 
the shelf unit upon mount and demount commands received from a host 
processor. The intermediate library level uses the same type of 
optical disk as used in the bottom level of the data storage hierarchy. 
An IO station in each of the automatic libraries enable manual access 
to the optical disk for transferring same between the intermediate and 
bottom levels. Preferably, the transfer is only from the intermediate 
level to the bottom level. Access to named storage objects in disks 
stored in the bottom level are through the stand-alone drives. A host 
processor has an independent access path to each level of the data 
storage hierarchy. A directory and other data structures indicate the 
number of copies made of each named data object and the location of 
such copies, such that the host processor 10 can independently access a 
copy from any level of the data storage hierarchy.

Patent EP-0711082-A3 (EP)
Inventor: HARUKI TOSHINOBU
IPC: H04N9/73
Filed: 1990-11-16
Abstract: 64 regions are set on an image sensed picture of a
video camera, where evaluating values r ij , b ij , and y ij  are
obtained by averaging color difference signals R-Y and B-Y
and luminance signal Y obtained from an image sensing
signal for over 1 field period by each region. When
determination is made that the difference in the
evaluating values between two continuing regions do not
exceed a predetermined value according to the obtained
evaluating values, that is, when determination is made
that continuing regions have the same color, the weighing
amount of the color evaluating values of a corresponding
region is reduced in producing gain control signals
regarding the color difference signals. As a result, the
effect of objects of the same color towards white balance
adjustment is reduced.

Abstract: Die Erfindung betrifft ein Verfahren zum bidirektionalen
Übertragen von hochratigen Digitalsignalen zwischen
wenigstens einer Basisstation und wenigstens einer
Kundeneinrichtung über eine Funkverbindung sowie eine
Basisstation zur Durchführung des Verfahrens und ein
digitales Funknetz. 
Die Erfindung löst das Problem, das bei der Übertragung von

zeitvariante Funkkanäle Übertragungsverfahren notwendig
sind, die mit möglichst geringem Aufwand die durch die
Eigenschaften des Funkkanals verursachten Beeinträchtigungen
der digitalen Signalübertragung minimieren. Dieses Problem
wird erfindungsgemäß dadurch gelöst, daß das von der
Kundeneinrichtung abgestrahlte Digitalsignal an wenigstens
zwei räumlich getrennt angeordneten Diversity-Antennen einer
Empfangseinrichtung der Basisstation empfangen wird. Das
Empfangssignal jeder Diversity-Antenne wird zunächst in den
Frequenzbereich transformiert und anschließend einer
Diversity-Kombination unterworfen. Das kombinierte Signal
wird danach im Frequenzbereich entzerrt und nach einer
Rücktransformation in den Zeitbereich einem Demodulator
