Patent EP-0361968-A3 (EP)
Title: Noise cancellor
IPC: G10K11/178
Filed: 1989-09-29
Abstract: A noise cancellor includes a first sensor (22) for 
detecting a noise generated form a driving device (10) 
and converting the noise to electric signals. A signal 
processor (25) receives the electric signals and forms 
control signals by multiplying the electric signals by a 
predetermined factor series. In response to the control 
signals, a speaker (30) produces sound which interferes 
with the noise so as to cancel the noise at an object 
point (13). A second sensor (26) detects sound at the 
object point and converts them to electric signals which 
are inputted to the signal processor. The signal proc­
essor switches the control mode, in accordance with a 
predetermined condition, to an adapting active control 
wherein the factor series is changed in response to the 
electric signal applied from the second sensor or an 
active control wherein the factor series is fixed.

Title: Fairness algorithm for full-duplex buffer insertion ring
IPC: H04L12/56
Filed: 1990-02-23
Abstract: The invention describes a method for transmitting data on a full-duplex buffer 
insertion ring. Access to the ring by each node is regulated by circulating control 
message around the ring. The message indicated to each node the maximum 
number of packets that it may transmit during the interval from the reception 
of one control message to the forwarding of a subsequent control message. With 
this invention a station need not be in possession of the control message in order 
to transmit a packet. A node will also hold a control message if it has not 
transmitted a predetermined minimum number of packets in its output buffer in 
a given time interval.

Patent EP-0476262-A3 (EP)
Title: Error handling in a vlsi central processor unit employing a pipelined address and execution module
IPC: G06F11/273
Filed: 1991-07-19
Abstract: An error handling facility is disclosed which includes a central processing unit (CPU) incorporating a basic processing unit (BPU) including a pipelined AX unit (as well as a decimal numeric - DN - unit and a floating point - FP - unit) having a plurality of software visible registers and which issues an AX ERROR signal in response, among others, to sensed errors occurring within the AX unit during the processing and execution of instructions. An auxiliary (XRAM) memory receives, via a cache unit, and temporarily stores a record of the contents of the software visible registers concurrently with the availability of the result of each instruction executed by the AX unit. A clock unit is coupled to receive the AX ERROR signal and responds by suspending clock signals to the BPU as well as notifying a service processor (SP) of the error occurrence. The relevant contents of the XRAM are also forwarded to the SP for analysis, and the SP can order a restart by issuing a "resume" signal to the clock unit after the information obtained from the XRAM has been analyzed and the failing CPU reinitialised as necessary. The issuance of an AX ERROR occurring in the pipeline activity signal is delayed until all instructions in the pipe ahead of the faulting instruction have completed execution. Alternatively, the delay can be extended until all instructions in the pipe ahead of and including the faulting instruction have completed execution. <IMAGE>

Patent EP-0716552-A3 (EP)
Inventor: YAMANE KAZUYASU
IPC: H04H20/74
Filed: 1995-12-07
Abstract: A service center (31) has a plurality of controlled
areas. When the service center (31) provides service
information through a radio communication network, the
service center first broadcasts toward all the areas with
outline items of the information with corresponding key
codes attached thereto. Users each receive the outline
items of the information with a user's terminal (2) and
determine as required whether a detail item of the
information should be had immediately (an urgent one) or
can be had later (a regular one). The results of the
determination are reported to the service center (31),
which immediately provides the urgent detail items of the
information for the respective users who made requests for
having those detail items. The service center (31)
broadcasts regular detail items of the information with
attached corresponding key codes other than the requested
urgent ones of the information toward the terminals which
requested the regular detail items of the information at a
predetermined time. Each terminal (2) has stored a key
code attached to the outline item of the information which
the terminal requested in a regular manner, and receives
only a necessary detail item of the information. The
service center (31) may count the number of requests,
determine the priority of provision of the detail items of
the information on the basis of the counted number of
requests, and omit provision of the detail items of the
information to areas which have not requested the detail
items of the information.

Title: Methods for producing coating powders, catalysts and drier water-borne coatings by spraying compositions with compressed fluids
Inventor: NIELSEN KENNETH ANDREW
IPC: B05D1/02
Filed: 1995-11-13
Abstract: This invention relates to methods for spraying liquid compositions containing volatile solvent by using compressed fluids, such as carbon dioxide or ethane, to form solid particulates, coating powders, and catalyst materials, which can be produced with narrow particle size distributions and can be sprayed at higher solids levels, in ambient air or with heated air applied to just the spray instead of a spray chamber. Novel catalyst supports can be produced having a beneficial morphology such as for olefin catalysis. Drier water-borne coatings can be applied to substrates by using compressed fluids to spray water-borne coating compositions having conventional water levels, thereby reducing runs and sags and shortening dry times.
