Title: Supersaturated rare earth doped semiconductor layers by cvd
Inventor: BEACH DAVID BRUCE
IPC: H01L21/205
Filed: 1993-07-30
Abstract: A CVD process for producing a rare earth-doped, epitaxial semiconductor layer on a substrate is disclosed. The equipment is a 7.6 cm diameter ultra high vacuum chemical vapor deposition (UHVCVD) reactor wherein pumping and wafer loading are done using the same end of the reactor. This modification allows the installation of a heated precursor reservoir (1) on the opposite end of the reactor. The reservoir is connected to the reactor end flange using a short diameter stainless steel tubing (12). The reactor is heated by external resistive heating (4). The reactor is pumped both before and during deposition by a 150 L/sec turbomolecular pump (8) backed by a two-stage oil pump (9). The load lock chamber is also pumped by a turbomolecular pump (10) to prevent contamination from pump oil.The process utilizes a silane or germane and a rare earth compound in the gas phase. By this method single phase, rare earth-doped semiconductor layers, supersaturated in the rare earth, are produced. The preferred rare earth is erbium and the preferred precursors for depositing erbium by CVD are erbium hexafluoroacetylacetonate, acetylacetonate, tetramethylheptanedionate and flurooctanedionate. The process may be used to produce optoelectronic devices comprising a silicon substrate and an erbium-doped epitaxial silicon film. <IMAGE>

Abstract: A point-to-multipoint communication system is presented to
enable a reliable, high quality communication using multiplexed
optical signals between a central office equipment (100) and a
plurality of subscriber's equipment (300,400,600). The system is provided
with a plurality of office transceivers (110,120) in the central office equipment
(100), and the each of the subscribers is provided with at least one subscriber
transceiver (310,320; 410,420; 620). The system is designed so
that a redundancy system is built-in by providing one of either
the office transceivers, a plurality of subscriber's
transceivers or the optical connection device, to connect the
two sets of transceivers at all times. One of these redundancy
systems provides an operating connection between each of the
office transmitters which are connected to the office
transceivers and each of the subscriber transmitters which are
connected to the subscriber transceivers. Therefore, when a
malfunction occurs somewhere in the optical network, the least
number of the malfunctioning components need to be switched over
the the normally functioning system to maintain continued
communication services. The present communication system is
designed with the least number of active components, therefore,
the failure probability is significantly decreased, and repairs
if necessary can be preformed quickly. The overall effect of
the present system is that interactive point-to-multipoint
communication services of high quality and reliability are
provided at reasonable cost.

IPC: H04J3/06
Filed: 1996-06-28
Abstract: A frequency error occurring in a repeater station (5) and
a receiving side radio station (4, 6-8) is determined by using
a dummy signal received from the repeater station, and is stored
as frequency control data corresponding to the frequency error
into a memory (209). By controlling a reception frequency based
on the stored frequency control data, a data signal received from
the repeater station is compensated for the frequency error. A
relatively large frequency error such as the common frequency
error occurring in the satellite (5) and the downconverter (7)
of the receiving side can be eliminated effectively.

Title: Verfahren und Vorrichtung zum Reduzieren des Energieverbrauchs bei einem durch einen Spannungswandler versorgten Elektrogerät
Inventor: DREUTH HANS JUERGEN
IPC: H02M5/257
Filed: 1996-08-06
Abstract: Bei dem Verfahren zur Reduzierung des Energieverbrauchs in durch Spannungswandler
versorgten Elektrogeräten wird der Spannungswandler über einen elektronischen oder
elektromechanischen Schalter von seiner Stromversorgung getrennt, um während der
Zeit der Trennung die Verluste im Spannungswandler zu vermeiden. 
"Spannungswandler" bezeichnet hier jedes Gerät, das die Betriebsspannung für das zu
versorgende Gerät anpaßt, insbesondere an das Netz angeschlossene Transformatoren
und sonstige Netzteile, sowie Versorgungsschaltungen wie z. B. DC-DC-Wandler, die
an sonstige elektrische Versorgungen (z.B. Akkumulatoren) angeschlossen sind. 
Während der Spannungswandler von seiner Stromversorgung getrennt ist, übernimmt
ein Energiespeicher die Versorgung des Verbrauchers. Der Zeitpunkt des
Wiedereinschaltens des Spannungswandlers wird vom Ladezustand des Energiespeichers
bestimmt bzw. vom aktuellen Energiebedarf des Gerätes. 
Da der Gesamtenergieverbrauch zahlreicher Geräte, wie Standby- oder anderer
Kleinverbraucher oft maßgeblich von den Verlusten im Spannungswandler bestimmt
werden, können durch das Verfahren (bzw. die entsprechende Vorrichtung) der
Gesamtenergiebedarf derartiger Geräte und damit Betriebskosten und
Umweltbelastungen reduziert werden.

determine whether the composite-repaired area is damaged or
undamaged. The baseline reference signal is obtained at
the time of the composite repair of the structure.
Patent EP-0738100-A3 (EP)
IPC: H05B37/02
Filed: 1996-04-01
Abstract: A timing device (11,12,16) which is associated with 
a light level sensor (10) and which is arranged to 
provide a time-out signal to a relay (13) after a 
predetermined time has elapsed following detection of a 
low light condition and initial energisation of the 
relay. The device provides for synchronisation of an 
initiation time T 1  and, hence, a time-out signal 
generating time T 2  with respect to a periodically 
occurring event time T 3  (for example, sunset time) in 
order that the desired time of generating the time-out 
signal might be re-established following interruption of 
power to the device. Should loss of power occur, the 
last entered event time T 3  is employed to synchronise the 
initiation time T 1  and, hence, the signal generating time 
T 2 , when detection of a predetermined light level next 
occurs following re-establishment of power to the device.

IPC: H04N7/50
Filed: 1997-01-14
Abstract: A method and apparatus for coding an image comprising (at least) two regions
( e.g.,  a facial region and a background region) which are to be coded with different
quantization error parameters ( e.g.,  quantizer step sizes), wherein the respective
quantization error parameters are determined with use of a feed-forward rate control
technique. Initial quantization error parameters are assigned to each region, and the overall
bit rate which would result for the coding of the given frame is computed based on these
assigned quantization error parameters. The computed bit rate is compared to a given bit
rate constraint which may, for example, represent a limitation of a transmission channel.
Based on the result of this comparison, one or both of the assigned quantization error
parameters are adjusted, thereby resulting in different quantization error parameters for the
two regions. For example, if the computed bit rate exceeds the given bit rate constraint,
at least one of the quantization error parameters is advantageously adjusted in a direction
which results in the use of fewer coding bits ( e.g.,  a coarser quantization). If the given bit
rate constraint exceeds the computed bit rate, at least one of the quantization error
parameters is advantageously adjusted in a direction which results in the use of more
coding bits ( e.g.,  a finer quantization resulting in a higher coding quality). Finally, each
of the regions is coded based on the correspondingly assigned quantization error
parameters.
